Criminal Prohibitions on the Publication of Classified Defense Information

Summary
The recent online publication of classified defense documents and diplomatic cables by the
organization WikiLeaks and subsequent reporting by the New York Times and other news media
have focused attention on whether such publication violates U.S. criminal law. The Attorney
General has reportedly stated that the Justice Department and Department of Defense are
investigating the circumstances to determine whether any prosecutions will be undertaken in
connection with the disclosure.
This report identifies some criminal statutes that may apply, but notes that these have been used
almost exclusively to prosecute individuals with access to classified information (and a
corresponding obligation to protect it) who make it available to foreign agents, or to foreign
agents who obtain classified information unlawfully while present in the United States. Leaks of
classified information to the press have only rarely been punished as crimes, and we are aware of
no case in which a publisher of information obtained through unauthorized disclosure by a
government employee has been prosecuted for publishing it. There may be First Amendment
implications that would make such a prosecution difficult, not to mention political ramifications
based on concerns about government censorship. To the extent that the investigation implicates
any foreign nationals whose conduct occurred entirely overseas, any resulting prosecution may
carry foreign policy implications related to the exercise of extraterritorial jurisdiction and whether
suspected persons may be extradited to the United States under applicable treaty provisions.
This report discusses the statutory prohibitions that may be implicated, including the Espionage
Act; the extraterritorial application of such statutes; and the First Amendment implications related
to such prosecutions against domestic or foreign media organizations and associated individuals.
The report provides a summary of recent legislation relevant to the issue as well as some previous
efforts to criminalize the unauthorized disclosure of classified information.

Criminal Prohibitions on the Publication of Classified Defense Information

he online publication of classified defense documents and diplomatic cables by the
organization WikiLeaks and subsequent reporting by the New York Times, the Guardian
T (UK), and Der Spiegel (Germany), among others, have focused attention on whether such
publication violates U.S. criminal law. The Attorney General has reportedly stated that the Justice
Department and Department of Defense are investigating the circumstances to determine whether
any prosecutions will be undertaken in connection with the disclosure,1 but has not released
sufficient factual findings to permit a full legal analysis. Accordingly, the following discussion
provides a general overview of the relevant law as it may apply to pertinent allegations reported
in the media, assuming them to be true. The discussion should not be interpreted to confirm the
truth of any allegations or establish that a particular statute has been violated.
Background
WikiLeaks.org describes itself as a “public service designed to protect whistle-blowers,
journalists and activists who have sensitive materials to communicate to the public.”2 Arguing
that “[p]rincipled leaking has changed the course of history for the better,” it states that its
purpose is to promote transparency in government and fight corporate fraud by publishing
information governments or corporations would prefer to keep secret, obtained from sources in
person, by means of postal drops, and by using “cutting-edge cryptographic technologies” to
receive material electronically.3 The organization promises contributors that their anonymity will
be protected.
According to press reports, WikiLeaks obtained more than 91,000 secret U.S. military reports
related to the war in Afghanistan and posted the majority of them, unredacted, on its website in
late July 2010, after first alerting the New York Times and two foreign newspapers, the Guardian
(London) and Der Spiegel (Germany), about the pending disclosure.4 Military officials have
reportedly said they suspect an Army private, Bradley Manning, of having leaked the documents
to WikiLeaks.5 Private Manning, a U.S. citizen, was already in military custody under suspicion
of having provided WikiLeaks with video footage of an airstrike that resulted in the deaths of
civilians.6 U.S. officials condemned the leaks, predicting that the information disclosed could lead
to the loss of lives of U.S. soldiers in Afghanistan and Afghan citizens who have provided them

assistance.7 Defense Secretary Robert M. Gates informed members of Congress that a preliminary
review of the disclosed information by the Defense Department found that no sensitive
information related to intelligence sources or methods was made public, but reiterated that the
release of Afghan informants’ names could have “potentially dramatic and grievously harmful
consequences.”8 WikiLeaks subsequently released some 400,000 documents related to the war in
Iraq,9 this time with names of informants apparently redacted.10
In late November 2010, WikiLeaks began publishing what the New York Times calls a “mammoth
cache of a quarter-million confidential American diplomatic cables,” dated for the most part
within the last three years.11 Wikileaks.org posted 220 cables on November 28, 2010, as a first
installment, some of which were redacted to protect diplomatic sources. The most recent
documents in the collection are reportedly dated February 2010.12
The United States government was aware of the impending disclosure, although not apparently
directly informed by the web-based anti-secrecy organization (or given access to the documents
to be released), although WikiLeaks Editor in Chief Julian Assange, in a letter sent to the U.S.
ambassador to the U.K., Louis Susman, offered to consider any U.S. requests to protect specific
information that the government believes could, if published, put any individuals at significant
risk of harm.13 The State Department Legal Adviser responded in a letter to Mr. Assange’s
attorney that the publication of classified materials violates U.S. law, that the United States will
not negotiate with WikiLeaks with respect to the publication of illegally obtained classified
documents, and that WikiLeaks should cease these activities and return all documents, as well as
delete any classified U.S. government material in its possession from its databases.14 Mr. Assange
responded by accusing the United States of adopting a confrontational stance and indicating an
intent to continue publishing the materials, subject to the checks WikiLeaks and its media
partners planned to implement to reduce any risk to individuals.15
After learning the classified cables were to be published, the Defense Department notified the
U.S. Senate and House Armed Services Committees in general terms about what to expect.16

Criminal Prohibitions on the Publication of Classified Defense Information

Assistant Secretary for Legislative Affairs Elizabeth King explained that “State Department
cables by their nature contain everyday analysis and candid assessments that any government
engages in as part of effective foreign relations,” and predicted that the publication of the
classified cables, which she described as intended to “wreak havoc and destabilize global
security,” could potentially jeopardize lives.17 State Department spokesman Philip J. Crowley told
Bloomberg that the State Department is “assessing the possible impact on our on-going
diplomatic activity and notifying both Congress and other governments what may occur.”18 The
White House issued a statement condemning the activities of WikiLeaks19 and ordered all
agencies to conduct reviews of their information security policies and programs.20
As of early January 2011, about 1% of the cables have been published, with WikiLeaks.org
posting only those cables that have already been released by the newspapers, as redacted by the
newspapers.21 The State Department is warning human rights activists, foreign government
officials, and businesspeople who are identified in the diplomatic cables that they may be at risk,
although their names have not been published thus far, and has relocated a few of them for their
safety.22
The publication of the leaked documents by WikiLeaks and the subsequent reporting of
information contained therein raise questions with respect to the possibility of bringing criminal
charges for the dissemination of materials by media organizations following an unauthorized
disclosure, in particular when done by non-U.S. nationals overseas. This report discusses the

19 White House, Statement of the Press Secretary, Nov. 28, 2010, at http://www.whitehouse.gov/the-press-office/2010/
11/28/statement-press-secretary. The statement reads in full:
We anticipate the release of what are claimed to be several hundred thousand classified State
department cables on Sunday night that detail private diplomatic discussions with foreign
governments. By its very nature, field reporting to Washington is candid and often incomplete
information. It is not an expression of policy, nor does it always shape final policy decisions.
Nevertheless, these cables could compromise private discussions with foreign governments and
opposition leaders, and when the substance of private conversations is printed on the front pages of
newspapers across the world, it can deeply impact not only US foreign policy interests, but those of
our allies and friends around the world. To be clear—such disclosures put at risk our diplomats,
intelligence professionals, and people around the world who come to the United States for
assistance in promoting democracy and open government. These documents also may include
named individuals who in many cases live and work under oppressive regimes and who are trying
to create more open and free societies. President Obama supports responsible, accountable, and
open government at home and around the world, but this reckless and dangerous action runs
counter to that goal. By releasing stolen and classified documents, Wikileaks has put at risk not
only the cause of human rights but also the lives and work of these individuals. We condemn in the
strongest terms the unauthorized disclosure of classified documents and sensitive national security
information.

statutory prohibitions that may be implicated; the extraterritorial application of such statutes; and
the First Amendment implications related to such prosecutions against domestic or foreign media
organizations and associated individuals.
Statutory Protection of Classified Information
While there is no one statute that criminalizes the unauthorized disclosure of any classified
information, a patchwork of statutes exists to protect information depending upon its nature, the
identity of the discloser and of those to whom it was disclosed, and the means by which it was
obtained. It seems likely that most of the information disclosed by WikiLeaks that was obtained
from Department of Defense databases falls under the general rubric of information related to the
national defense. The diplomatic cables obtained from State Department channels may also
contain information relating to the national defense and thus be covered under the Espionage Act,
but otherwise their disclosure by persons who are not government employees does not appear to
be directly proscribed.23 It is possible that some of the government information disclosed in any
of the three releases does not fall under the express protection of any statute, despite its classified
status.
The Espionage Act
National defense information in general is protected by the Espionage Act,24 18 U.S.C. §§ 793–
798, while other types of relevant information are covered elsewhere. Some provisions apply only
to government employees or others who have authorized access to sensitive government
information,25 but many apply to all persons. 18 U.S.C. § 793 prohibits the gathering,
transmitting, or receipt of defense information with the intent or reason to believe the information
will be used against the United States or to the benefit of a foreign nation. Violators are subject to
a fine or up to 10 years’ imprisonment, or both,26 as are those who conspire to violate the statute.27

23 See 18 U.S.C. § 952 (prohibiting the disclosure or publication of certain diplomatic material obtained “by virtue of
… employment by the United States”).
24 Act of October 6, 1917, ch. 106, § 10(i), 40 Stat. 422.
25 E.g., 18 U.S.C. §§ 952 (prohibiting disclosure of diplomatic codes and correspondence), 1924 (unauthorized removal
and retention of classified documents or material); 50 U.S.C. § 783 (unauthorized disclosure of classified information
to an agent of a foreign government, unauthorized receipt by foreign government official).
26 18 U.S.C. § 793(a)-(c) provides:
(a) Whoever, for the purpose of obtaining information respecting the national defense with intent or
reason to believe that the information is to be used to the injury of the United States, or to the
advantage of any foreign nation, goes upon, enters, flies over, or otherwise obtains information
concerning any vessel, aircraft, work of defense, [etc.], or any prohibited place so designated by the
President by proclamation in time of war or in case of national emergency in which anything for
the use of the Army, Navy, or Air Force is being prepared or constructed or stored, information as
to which prohibited place the President has determined would be prejudicial to the national defense;
or
(b) Whoever, for the purpose aforesaid, and with like intent or reason to believe, copies, takes,
makes, or obtains, or attempts to copy, take, make, or obtain any sketch, photograph, photographic
negative, blueprint, plan, map, model, instrument, appliance, document, writing, or note of
anything connected with the national defense; or
(c) Whoever, for the purpose aforesaid, receives or obtains or agrees or attempts to receive or
obtain from any person, or from any source whatever, any [protected thing] connected with the
national defense, knowing or having reason to believe ... that it has been or will be obtained, taken,

Criminal Prohibitions on the Publication of Classified Defense Information

Persons who possess defense information that they have reason to know could be used to harm
the national security, whether the access is authorized or unauthorized, and who disclose that
information to any person not entitled to receive it, or who fail to surrender the information to an
officer of the United States, are subject to the same penalty.28 Although it is not necessary that the
information be classified by a government agency, the courts seem to give deference to the
executive determination of what constitutes “defense information.”29 Information that is made
available by the government to the public is not covered under the prohibition, however, because
public availability of such information negates the bad-faith intent requirement.30 On the other
hand, classified documents remain within the ambit of the statute even if information contained
therein is made public by an unauthorized leak.31
18 U.S.C. § 794 (aiding foreign governments or communicating information to an enemy in time
of war) covers “classic spying” cases,32 providing for imprisonment for any term of years or life,
or under certain circumstances, the death penalty.33 The provision penalizes anyone who transmits

(...continued)
made, or disposed of by any person contrary to the provisions of this chapter [18 U.S.C. §§ 792 et
seq
.]....
27 18 U.S.C. § 793(g) provides:
If two or more persons conspire to violate any of the foregoing provisions of this section, and one
or more of such persons do any act to effect the object of the conspiracy, each of the parties to such
conspiracy shall be subject to the punishment provided for the offense which is the object of such
conspiracy.
28 18 U.S.C. § 793(e) provides:
Whoever having unauthorized possession of, access to, or control over any document [or other
protected thing], or information relating to the national defense which information the possessor
has reason to believe could be used to the injury of the United States or to the advantage of any
foreign nation, willfully communicates, delivers, transmits ... to any person not entitled to receive
it, or willfully retains the same and fails to deliver it to the officer or employee of the United States
entitled to receive it; … Shall be fined under this title or imprisoned not more than ten years, or
both.
§ 793(d) is identical to § 794(e), except that it applies to persons with authorized access to the information at
issue, in which case it is only an offense to retain or fail to turn the information over to a government official
if there was a demand for its return.
§ 793(f) likewise applies only to those with authorized access to the covered materials, punishing those who
(1) through gross negligence permits the same to be removed from its proper place of custody or
delivered to anyone in violation of his trust, or to be lost, stolen, abstracted, or destroyed, or
(2) having knowledge that the same has been illegally removed from its proper place of custody or
delivered to anyone in violation of its trust, or lost, or stolen, abstracted, or destroyed, and fails to
make prompt report of such loss, theft, abstraction, or destruction to his superior officer.
29 The government must demonstrate that disclosure of the information is at least “potentially damaging” to the United
States or advantageous to a foreign government. See United States v. Morison, 844 F.2d 1057, 1072 (4th Cir.), cert.
denied
, 488 U.S. (1988)(upholding conviction under 18 U.S.C. § 793 for delivery of classified photographs to
publisher). Whether the information is “related to the national defense” under this meaning is a question of fact for the
jury to decide. Id. at 1073.
30 Gorin v. United States, 312, U.S. 9, 27-28 (1941) (“Where there is no occasion for secrecy, as with reports relating to
national defense, published by authority of Congress or the military departments, there can, of course, in all likelihood
be no reasonable intent to give an advantage to a foreign government.”).
31 United States v. Squillacote, 221 F.3d 542, 578 (4th Cir. 2000).
32 Morison, 844 F.2d at 1064-65 (explaining that critical element distinguishing § 794 from § 793 is the requirement
that disclosure be made to an agent of a foreign government rather than anyone not entitled to receive it).

defense information to a foreign government (or foreign political or military party) with the intent
or reason to believe it will be used against the United States. It also prohibits attempts to elicit
information related to the public defense “which might be useful to the enemy.”34 The death
penalty is available only upon a finding that the offense resulted in the death of a covert agent or
directly concerns nuclear weapons or other particularly sensitive types of information. The death
penalty is also available under § 794 for violators who gather, transmit or publish information
related to military plans or operations and the like during time of war, with the intent that the
information reach the enemy.35 These penalties are available to punish any person who
participates in a conspiracy to violate the statute. Offenders are also subject to forfeiture of any
ill-gotten gains and property used to facilitate the offense.36
The unauthorized creation, publication, sale or transfer of photographs or sketches of vital
defense installations or equipment as designated by the President is prohibited by 18 U.S.C.
§§ 795 and 797.37 Violators are subject to fine or imprisonment for not more than one year, or
both.

(...continued)
(a) Whoever, with intent or reason to believe that it is to be used to the injury of the United States
or to the advantage of a foreign nation, communicates, delivers, or transmits ... to any foreign
government, or to any faction or party or military or naval force within a foreign country, whether
recognized or unrecognized by the United States, or to any representative, officer, agent, employee,
subject, or citizen thereof, either directly or indirectly, any document [or other protected thing], or
information relating to the national defense, shall be punished by death or by imprisonment for any
term of years or for life, except that the sentence of death shall not be imposed unless the jury or ...
the court, further finds that the offense resulted in the identification by a foreign power (as defined
in section 101(a) of the Foreign Intelligence Surveillance Act of 1978 [50 U.C.S. § 1801(a)]) of an
individual acting as an agent of the United States and consequently in the death of that individual,
or directly concerned nuclear weaponry, military spacecraft or satellites, early warning systems, or
other means of defense or retaliation against large-scale attack; war plans; communications
intelligence or cryptographic information; or any other major weapons system or major element of
defense strategy.
34 § 794(b) provides:
(b) Whoever, in time of war, with intent that the same shall be communicated to the enemy,
collects, records, publishes, or communicates, or attempts to elicit any information with respect to
the movement, numbers, description, condition, or disposition of any of the Armed Forces, ships,
aircraft, or war materials of the United States, or with respect to the plans or conduct, or supposed
plans or conduct of any naval or military operations, or with respect to any works or measures
undertaken for or connected with, or intended for the fortification or defense of any place, or any
other information relating to the public defense, which might be useful to the enemy, shall be
punished by death or by imprisonment for any term of years or for life....
35 During time of war, any individual who communicates intelligence or any other information to the enemy may be
prosecuted by the military for aiding the enemy under Article 104 of the Uniform Code of Military Justice (UCMJ),
and if convicted, punished by “death or such other punishment as a court-martial or military commission may direct.”
10 U.S.C. § 904.
36 18 U.S.C. § 794(d). Proceeds go to the Crime Victims Fund.
37 § 795. Photographing and sketching defense installations
(a) Whenever, in the interests of national defense, the President defines certain vital military and
naval installations or equipment as requiring protection against the general dissemination of
information relative thereto, it shall be unlawful to make any photograph, sketch, picture, drawing,
map, or graphical representation of such vital military and naval installations or equipment without
first obtaining permission of the commanding officer of the military or naval post, camp, or station,
or naval vessels, military and naval aircraft, and any separate military or naval command
concerned, or higher authority, and promptly submitting the product obtained to such commanding
officer or higher authority for censorship or such other action as he may deem necessary....

Criminal Prohibitions on the Publication of Classified Defense Information

The knowing and willful disclosure of certain classified information is punishable under 18
U.S.C. § 798 by fine and/or imprisonment for not more than 10 years.38 To incur a penalty, the
disclosure must be prejudicial to the safety or interests of the United States or work to the benefit
of any foreign government and to the detriment of the United States. The provision applies only
to information related to cryptographic systems or communications intelligence that is specially
designated by a U.S. government agency for “limited or restricted dissemination or
distribution.”39
Members of the military40 who commit espionage, defined similarly to the conduct prohibited in
18 U.S.C. § 794, may be tried by court-martial for violating Article 106a of the Uniform Code of
Military Justice (UCMJ),41 and sentenced to death if certain aggravating factors are found by

§ 797. Publication and sale of photographs of defense installations
On and after thirty days from the date upon which the President defines any vital military or naval
installation or equipment as being within the category contemplated under section 795 of this title
[18], whoever reproduces, publishes, sells, or gives away any photograph, sketch, picture, drawing,
map, or graphical representation of the vital military or naval installations or equipment so defined,
without first obtaining permission of the commanding officer ... or higher authority, unless such
photograph, sketch, picture, drawing, map, or graphical representation has clearly indicated thereon
that it has been censored by the proper military or naval authority, shall be fined under this title or
imprisoned not more than one year, or both.
38 § 798. Disclosure of classified information
(a) Whoever knowingly and willfully communicates, furnishes, transmits, or otherwise makes
available to an unauthorized person, or publishes, or uses in any manner prejudicial to the safety or
interest of the United States or for the benefit of any foreign government to the detriment of the
United States any classified information—
(1) concerning the nature, preparation, or use of any code, cipher, or cryptographic system of the
United States or any foreign government; or
(2) concerning the design, construction, use, maintenance, or repair of any device, apparatus, or
appliance used or prepared or planned for use by the United States or any foreign government for
cryptographic or communication intelligence purposes; or
(3) concerning the communication intelligence activities of the United States or any foreign
government; or

unanimous determination of the panel.42 Unlike offenses under § 794, Article 106a offenses need
not have resulted in the death of a covert agent or involve military operations during war to incur
the death penalty. One of the aggravating factors enabling the imposition of the death penalty
under Article 106a is that “[t]he accused has been convicted of another offense involving
espionage or treason for which either a sentence of death or imprisonment for life was authorized
by statute.”
However, the government is not limited to charging the offense of espionage under Article 106a,
discussed above. Members could also be tried by court-martial for violations of Article 92, failure
to obey order or regulation,43 Article 104, aiding the enemy,44 or under the general article, Article
134.45 Article 134 offenses include “all disorders and neglects to the prejudice of good order and

18 U.S.C. § 1030(a)(1) punishes the willful retention, communication, or transmission, etc., of
classified information retrieved by means of knowingly accessing a computer without (or in
excess of) authorization, with reason to believe that such information “could be used to the injury
of the United States, or to the advantage of any foreign nation.” Receipt of information procured
in violation of the statute is not addressed, but depending on the specific facts surrounding the
unauthorized access, criminal culpability might be asserted against persons who did not
themselves access a government computer as conspirators, aiders and abettors, or accessories
after the fact.47 The provision imposes a fine or imprisonment for not more than 10 years, or both,

sentence of up to 20 years.
18 U.S.C. § 641 punishes the theft or conversion of government property or records for one’s own
use or the use of another. While this section does not explicitly prohibit disclosure of classified
information, it has been used to prosecute “leakers.”48 Violators may be fined, imprisoned for not
more than 10 years, or both, unless the value of the property does not exceed the sum of $100, in
which case the maximum prison term is one year. The statute also covers knowing receipt or
retention of stolen or converted property with the intent to convert it to the recipient’s own use. It
does not appear to have been used to prosecute any recipients of classified information even
where the original discloser was charged under the statute.
50 U.S.C. § 421 provides for the protection of information concerning the identity of covert
intelligence agents.49 It generally covers persons authorized to know the identity of such agents or
who learn the identify of covert agents as a result of their general access to classified
information,50 but can also apply to a person who learns of the identity of a covert agent through a
“pattern of activities intended to identify and expose covert agents” and discloses the identity to
any individual not authorized access to classified information, with reason to believe that such
activities would impair U.S. foreign intelligence efforts. This crime is subject to a fine or
imprisonment for a term of not more than three years. To be convicted, a violator must have
knowledge that the information identifies a covert agent whose identity the United States is taking
affirmative measures to conceal. To date, there have been no reported cases interpreting the
statute, but it did result in one conviction pursuant to a guilty plea.51

to include a non-U.S. citizen “whose past or present intelligence relationship to the United States is classified
information and who is a present or former agent of, or a present or former informant or source of operational
assistance to, an intelligence agency.” 50 U.S.C. § 426(4)(c). “Intelligence agency” is defined to include a “foreign
intelligence component of the Department of Defense”; informant means “any individual who furnishes information to
an intelligence agency in the course of a confidential relationship.” 50 U.S.C. § 426(5-6). The definitions suggest that
the act is intended to protect the identities of persons who provide intelligence information directly to a military
counterintelligence unit, but perhaps they can be read to cover those who provide information to military personnel
carrying out other functions who provide situation reports intended to reach an intelligence component. In any event,
the extraterritorial application of the statute is limited to U.S. citizens and permanent resident aliens. 50 U.S.C. § 424.
50 Persons with direct access to information regarding the identities are subject to a prison term of not more than 10
years, while those who learn the identities through general access to classified information are subject to a term not
greater than five years. 50 U.S.C. § 421. Charges of conspiracy, aiding and abetting, or misprision of felony are not
available in connection with the offense, except in the case of a person who engaged in a pattern of activities to disclose
the identities of covert agents or persons with authorized access to classified information. 50 U.S.C. § 422(b).

Criminal Prohibitions on the Publication of Classified Defense Information

18 U.S.C. § 1924 prohibits the unauthorized removal of classified material by government
employees, contractors, and consultants who come into possession of the material by virtue of
their employment by the government.52 The provision imposes a fine of up to $1,000 and a prison
term up to one year for offenders who knowingly remove material classified pursuant to
government regulations concerning the national defense or foreign relations of the United States,
with the intent of retaining the materials at an unauthorized location.53
There appears to be no statute that generally proscribes the acquisition or publication of
diplomatic cables, although government employees who disclose such information without proper
authority may be subject to prosecution. 18 U.S.C. § 952 punishes employees of the United States
who, without authorization, willfully publish or furnish to another any official diplomatic code or
material prepared in such a code, by imposing a fine, a prison sentence (up to 10 years), or both.
The same punishment applies for materials “obtained while in the process of transmission
between any foreign government and its diplomatic mission in the United States,”54 but not,
apparently, materials obtained during transmission from U.S. diplomatic missions abroad to the
State Department or vice versa (unless the material was or purports to have been prepared using
an official diplomatic code – it is unclear whether messages that are encrypted for transmission
are covered). The removal of classified material concerning foreign relations with the intent to
store them at an unauthorized location is a misdemeanor under 18 U.S.C. § 1924, which also
applies only to U.S. government employees.
50 U.S.C. § 783 penalizes government officers or employees who, without proper authority,
communicate classified information to a person whom the employee has reason to suspect is an
agent or representative of a foreign government.55 It is also unlawful for the representative or

52 18 U.C.S. § 1924 provides:

materials containing classified information of the United States, knowingly removes such
documents or materials without authority and with the intent to retain such documents or materials
at an unauthorized location shall be fined not more than $ 1,000, or imprisoned for not more than
one year, or both.
(b) For purposes of this section, the provision of documents and materials to the Congress shall not
constitute an offense under subsection (a).
(c) In this section, the term “classified information of the United States” means information
originated, owned, or possessed by the United States Government concerning the national defense
or foreign relations of the United States that has been determined pursuant to law or Executive
order to require protection against unauthorized disclosure in the interests of national security.

by which this officer or employee is employed, to make such disclosure of such information.

provisions is punishable by a fine of up to $10,000 or imprisonment for not more than 10 years.57
Violators are thereafter prohibited from holding federal public office.58 Violators must forfeit all
property derived directly or indirectly from the offense and any property that was used or
intended to be used to facilitate the violation.59
Analysis
In light of the foregoing, it seems that there is ample statutory authority for prosecuting
individuals who elicit or disseminate many of the documents at issue, as long as the intent
element can be satisfied and potential damage to national security can be demonstrated.60 There is
some authority, however, for interpreting 18 U.S.C. § 793, which prohibits the communication,
transmission, or delivery of protected information to anyone not entitled to possess it, to exclude
the “publication” of material by the media.61 Publication is not expressly proscribed in 18 U.S.C.
§ 794(a), either, although it is possible that publishing covered information in the media could be
construed as an “indirect” transmission of such information to a foreign party, as long as the
intent that the information reach said party can be demonstrated.62 The death penalty is available
under that subsection if the offense results in the identification and subsequent death of “an
individual acting as an agent of the United States,”63 or the disclosure of information relating to

department or agency thereof, any information of a kind which shall have been classified by the
President (or by the head of any such department, agency, or corporation with the approval of the
President) as affecting the security of the United States, unless special authorization for such
communication shall first have been obtained from the head of the department, agency, or
corporation having custody of or control over such information.

believe that the information is to be used [or could be used] to the injury of the United States, or to the advantage of
any foreign nation.” 18 U.S.C. §§ 793 and 794. This has been interpreted to require the prosecution to demonstrate a
“bad purpose.” See United States v. Morison, 844 F.2d 1057, 1071 (“An act is done willfully if it is done voluntarily
and intentionally and with the specific intent to do something that the law forbids. That is to say, with a bad purpose
either to disobey or to disregard the law.”). If any of the disclosed material involves communications intelligence as
described in 18 U.S.C. § 798, the conduct must be undertaken knowingly and willfully to meet the intent threshold.

certain other broadly defined defense matters. The word “publishes” does appear in 18 U.S.C.
§ 794(b), which applies to wartime disclosures of information related to the “public defense” that
“might be useful to the enemy” and is in fact intended to be communicated to the enemy. The
types of information covered seem to be limited to military plans and information about
fortifications and the like, which may exclude data related to purely historical matters.
Moreover, the statutes described in the previous section have been used almost exclusively to
prosecute individuals with access to classified information (and a corresponding obligation to
protect it) who make it available to foreign agents, or to foreign agents who obtain classified
information unlawfully while present in the United States. Leaks of classified information to the
press have only rarely been punished as crimes, and we are aware of no case in which a publisher
of information obtained through unauthorized disclosure by a government employee has been
prosecuted for publishing it. There may be First Amendment implications that would make such a
prosecution difficult, not to mention political ramifications based on concerns about government
censorship. To the extent that the investigation implicates any foreign nationals whose conduct
occurred entirely overseas, any resulting prosecution may carry foreign policy implications
related to the exercise of extraterritorial jurisdiction and whether suspected persons may be
extradited to the United States under applicable treaty provisions.
Jurisdictional Reach of Relevant Statutes
The Espionage Act gives no express indication that it is intended to apply extraterritorially, but
courts have not been reluctant to apply it to overseas conduct of Americans, in particular because
Congress in 1961 eliminated a provision restricting the act to apply only “within the admiralty
and maritime jurisdiction of the United States and on the high seas, as well as within the United
States.”64 This does not answer the question whether the act is intended to apply to foreigners
outside the United States. Because espionage is recognized as a form of treason,65 which
generally applies only to persons who owe allegiance to the United States, it might be supposed
that Congress did not regard it as a crime that could be committed by aliens with no connection to
the United States. However, the only court that appears to have addressed the question concluded
otherwise.66 A district court judge held in 1985 that a citizen of East Germany could be
prosecuted under §§ 793(b), 794(a) and 794(c) for having (1) unlawfully sought and obtained
information regarding the U.S. national defense, (2) delivered that information to his own
government, and (3) conspired to do so with the intent that the information be used to the injury
of the United States or to the advantage of the German Democratic Republic, all of which

offenses were committed within East Germany or in Mexico. The court rejected the defendant’s
contention that construing the act to cover him would permit the prosecution of noncitizens “who
might merely have reviewed defense documents supplied to them by their respective
governments.”67 The court considered the scenario unlikely, stating:
Under the statutorily defined crimes of espionage in §§ 793 and 794, noncitizens would be
subject to prosecution only if they actively sought out and obtained or delivered defense
information to a foreign government or conspired to do so.68
Under this construction, it is possible that noncitizens involved in publishing materials disclosed
to them by another would be subject to prosecution only if it can be demonstrated that they took
an active role in obtaining the information. The case was not appealed. The defendant, Dr. Alfred
Zehe, pleaded guilty in February, 1985 and was sentenced to eight years in prison, but was traded
as part of a “spy swap” with East Germany in June of that year.69
Application of the Espionage Act to persons who do not hold a position of trust with the
government, outside of the classic espionage scenario (in which an agent of a foreign government
delivers damaging information to such hostile government), has been controversial. The only
known case of that type involved two pro-Israel lobbyists in Washington, Steven J. Rosen and
Keith Weissman, associated with the American Israel Public Affairs Committee (AIPAC), who
were indicted in 2005 for conspiracy to disclose national security secrets to unauthorized
individuals, including Israeli officials, other AIPAC personnel, and a reporter for the Washington
Post
.70 Their part in the conspiracy amounted to receiving information from government
employees with knowledge that the employees were not authorized to disclose it.71 The
prosecution was criticized for effectively “criminalizing the exchange of information,”72 based in
part on the government’s theory that the defendants were guilty of solicitation of classified
information because they inquired into matters they knew their government informant was not
permitted to discuss, something that many journalists consider to be an ordinary part of their
job.73 Charges were eventually dropped, reportedly due to a judge’s ruling regarding the

government’s burden of proving the requisite intent and concerns that classified information
would have to be disclosed at trial.74
Extradition Issues75
Assuming that the Espionage Act does apply to foreign nationals for their conduct overseas, there
may be several legal obstacles to the extradition of such a suspect to the United States to face
charges under the statute, including the possibility that the crime constitutes a political offense for
which extradition is unavailable. Extradition to or from the United States is almost exclusively a
creature of treaty. The United States has extradition treaties with more than 100 countries,
although there are many countries with which it does not.76 In addition to providing an explicit
list of crimes for which extradition may be granted, most modern extradition treaties also identify
various classes of offenses and situations for which extradition may or must be denied.
The “political offense” exception has been a common feature of extradition treaties for almost a
century and a half, and the exception appears to be contained in every modern U.S. extradition
treaty.77 A political offense may be characterized as a pure political offense, or one that is directed
singularly at a sovereign entity and does not have the features an ordinary crime (e.g., there is no
violation of the private rights of individuals),78 or as a relative political offense, meaning an
“otherwise common crime[] committed in connection with a political act … or common crimes
… committed for political motives or in a political context.”79
The political offense exception may pose a significant obstacle to the extradition of a foreign
national to the United States to face charges under the Espionage Act. Espionage, along with
treason and sedition, has been recognized as a quintessential example of a purely political

74 See Markon, supra footnote 70 (quoting Dana J. Boente, the acting U.S. attorney in Alexandria, VA, where the trial
was scheduled to take place). The judge found the scienter requirement of 18 U.S.C. § 793 to require that the
defendants must have reason to believe the communication of the information at issue “could be used to the injury of
the United States or to the advantage of any foreign nation.” 445 F. Supp. 2d at 639. Moreover, the judge limited the
definition of “information related to the national defense” to information that is “potentially damaging to the United
States or ... useful to an enemy of the United States.” Id. (citing United States v. Morison, 844 F.2d 1057, 1084 (4th Cir.

offense,80 although this recognition may arguably apply only to the “classic case” of espionage on
behalf of a foreign government by one who owes allegiance to the aggrieved government.81 Even
if the political offense exception applies to the unauthorized disclosure of national defense
information, however, the United States could still seek the extradition of a suspect to face other
criminal charges (though it would likely be unable to try the fugitive for an offense other than the
one for which he was extradited),82 although extradition might be refused if the charged conduct
is deemed to have been committed in furtherance of an act of espionage (or other political
offense).83
Extradition is also generally limited to crimes identified in the relevant treaty. Early extradition
treaties concluded by the United States typically listed specific crimes constituting extraditable
offenses. More recent agreements often adopt a dual criminality approach, in which extradition is
available when each party recognizes a particular form of misconduct as a punishable offense
(subject to other limitations found elsewhere in the applicable extradition treaty).84 No U.S.
extradition treaty currently in force lists espionage as an extraditable offense.85 Assuming for the
sake of argument that certain espionage offenses are not per se political offenses for which
extradition may not be granted, it would appear that the United States could only seek the
extradition of a foreign national for an espionage offense if the applicable treaty authorized
extradition in cases of dual criminality, and the requested state recognized espionage (or perhaps

BASSIOUNI, supra footnote 78, at 604.
81 It might be argued that certain offenses punishable under the Espionage Act do not fall under the traditional
conception of “espionage,” and should therefore not be deemed to be pure political offenses per se. See generally
PIETRO VERRI, DICTIONARY OF THE INTERNATIONAL LAW OF ARMED CONFLICT 47 (1992) (espionage is “commonly
applied to the efforts made in territory under enemy control by a party to the conflict to collect all information on the
enemy that may be useful to the conduct of the war in general and to that of hostilities in particular....The word
espionage is also applied to the collection by States, in peacetime as well as in time of war, of political and military
information regarding each other.”); Lt. Col. Geoffrey B. Demarest, Espionage in International Law, 24 DENV. J. INT'L
L. & POL'Y 321, 324 (1996) (“Throughout history, the terms ‘espionage’ and ‘spying’ have carried varying amounts of
pejorative baggage. Therefore, any attempt at a precise definition is difficult.”). Nonetheless, such an offense might still
be deemed to be sufficiently related to political action or informed by political motivations so as to fall under the
political offense exception.

unauthorized receipt or disclosure of protected government information) as a criminal offense
under its domestic laws.
Whether extradition is available for an offense occurring outside the United States may depend in
part upon whether the applicable treaty covers extraterritorial offenses. As a general rule, crimes
are defined by the laws of the place where they are committed.86 Nations have always been
understood to have authority to outlaw and punish conduct occurring outside the confines of their
own territory under some circumstances, but the United States now claims more sweeping
extraterritorial application for some of its criminal laws than is recognized either in its more
historic treaties or by many of today’s governments.87 This may complicate any extradition efforts
because many U.S. extradition treaties apply only to crimes “committed within the [territorial]
jurisdiction” of the country seeking extradition.88 Some contemporary treaties call for extradition
regardless of where the offense was committed, while perhaps an equal number permit or require
denial of an extradition request that falls within an area where the countries hold conflicting
views on extraterritorial jurisdiction.89
The extradition of a foreign national to the United States to face criminal charges may be
impeded by nationality provisions contained in extradition treaties with many countries, which
recognize the right of a requested party to refuse to extradite its own nationals. U.S. extradition
agreements generally are either silent with respect to nationality, in which case all persons are
subject to extradition without regard to their nationality, or they contain a nationality clause that
specifies that parties are not bound to deliver up their own nationals, in some cases leaving room
for executive discretion.90 Some newer treaties declare that “extradition shall not be refused based
on the nationality of the person sought,” while others limit the nationality exemption to
nonviolent crimes or bar nationality from serving as the basis to deny extradition when the
fugitive is sought in connection with a listed offense.
The ability of the United States to obtain the extradition of a fugitive for a criminal offense may
also be impacted by the existence of competing extradition requests made by other States. The
criteria used by a requested State to determine the precedence given to competing extradition
requests may be established either by its domestic laws or via its extradition treaties with the
requesting countries.91 If the requested State opts to give priority to the extradition request of
another country, it might still be possible for the United States to obtain the extradition of the
fugitive at a later date. Whether a fugitive extradited to one State can thereafter be extradited to a
third country may depend upon the applicable treaties between the relevant States. Some

extradition agreements authorize the requesting State to re-extradite a person to a third country in
certain circumstances. Generally, re-extradition is only permitted when the State from whom
extradition was initially obtained consents to the re-extradition of the fugitive, or the fugitive
voluntarily remains in the State where he was initially extradited for a specified period after
having been released from custody.92
Constitutional Issues
The publication of information pertaining to the national defense or foreign policy may serve the
public interest by providing citizens with information necessary to shed light on the workings of
government, but it seems widely accepted that the public release of at least some of such
information poses a significant enough threat to the security of the nation that the public interest
is better served by keeping it secret. The Constitution protects the public right to access
government information and to express opinions regarding the functioning of the government,
among other things, but it also charges the government with “providing for the common defense.”
Policymakers are faced with the task of balancing these interests.
The First Amendment to the U.S. Constitution provides: “Congress shall make no law ...
abridging the freedom of speech, or of the press....”93 Despite this absolute language, the Supreme
Court has held that “[t]he Government may ... regulate the content of constitutionally protected
speech in order to promote a compelling interest if it chooses the least restrictive means to further
the articulated interest.”94
Where speech is restricted based on its content, the Supreme Court generally applies “strict
scrutiny,” which means that it will uphold a content-based restriction only if it is necessary “to
promote a compelling interest,” and is “the least restrictive means to further the articulated
interest.”95 Protection of the national security from external threat is without doubt a compelling
government interest.96 It has long been accepted that the government has a compelling need to
suppress certain types of speech, particularly during time of war or heightened risk of hostilities.97

92 See, e.g., Swedish Extradition Treaty, art. IX, entered into force Dec. 3, 1963, 14 U.S.T. 1845 (“A person extradited
by virtue of this Convention may not be tried or punished by the requesting State for any offense committed prior to his
extradition, other than that which gave rise to the request, nor may he be re-extradited by the requesting State to a third
country which claims him, unless the surrendering State so agrees or unless the person extradited, having been set at
liberty within the requesting State, remains voluntarily in the requesting State for more than 45 days from the date on
which he was released. Upon such release, he shall be informed of the consequences to which his stay in the territory of
the requesting State might subject him.”); Turkish Extradition Treaty, art. 17, entered into force Jan. 1, 1987, 32 UST
2111 (similar). See also Council of Europe, Convention on Extradition, art. 15, done Dec. 13, 1957 (providing similar

Speech likely to incite immediate violence, for example, may be suppressed.98 Speech that would
give military advantage to a foreign enemy is also susceptible to government regulation.99
Where First Amendment rights are implicated, it is the government’s burden to show that its
interest is sufficiently compelling to justify enforcement. Whether the government has a
compelling need to punish disclosures of classified information turns on whether the disclosure
has the potential of causing damage to the national defense or foreign relations of the United
States.100 Actual damage need not be proved, but potential damage must be more than merely
speculative and incidental.101 On the other hand, the Court has stated that “state action to punish
the publication of truthful information seldom can satisfy constitutional standards.”102 And it has
described the constitutional purpose behind the guarantee of press freedom as the protection of
“the free discussion of governmental affairs.”103
Although information properly classified in accordance with statute or executive order carries by
definition, if disclosed to a person not authorized to receive it, the potential of causing at least
identifiable harm to the national security of the United States,104 it does not necessarily follow

national interest); Elrod v. Burns, 427 U.S. 347, 362 (1976) (“The interest advanced must be paramount, one of vital

103 Mills v. Alabama, 384 U.S. 214, 218 (1966). Because of the First Amendment purpose to protect the public’s ability
to discuss governmental affairs along with court decisions denying that it provides any special rights to journalists, e.g.,
Branzburg v. Hayes, 408 U.S. 665 (1972), it is not likely a plausible argument to posit that it does not apply to the
foreign press. See United States v. 18 Packages of Magazines 238 F. Supp. 846, 847-848 (D.C. Cal. 1964) (“Even if it
be conceded, arguendo, that the ‘foreign press’ is not a direct beneficiary of the Amendment, the concession gains
nought for the Government in this case. The First Amendment does protect the public of this country. … The First
Amendment surely was designed to protect the rights of readers and distributors of publications no less than those of
writers or printers. Indeed, the essence of the First Amendment right to freedom of the press is not so much the right to
print as it is the right to read. The rights of readers are not to be curtailed because of the geographical origin of printed
materials.”). The Supreme Court invalidated, on First Amendment grounds, a statute that required postal authorities to
detain unsealed mail from abroad deemed to contain “communist political propaganda” unless the recipient affirms a
desire to receive it. Lamont v. Postmaster General, 381 U.S. 301 (1965).
Likewise, the fact that WikiLeaks is not a typical newsgathering and publishing organization would likely make little
difference under First Amendment analysis. The Supreme Court has not established clear boundaries between the
protection of speech and that of the press, nor has it sought to develop criteria for identifying what constitutes “the
press” that might qualify its members for privileges not available to anyone else. See generally CONGRESSIONAL

that government classification by itself will be dispositive of the issue in the context of a criminal
trial. However, courts have adopted as an element of the espionage statutes a requirement that the
information at issue must be “closely held.”105 Government classification will likely serve as
strong evidence to support that contention, even if the information seems relatively innocuous or
does not contain much that is not already publicly known.106 Typically, courts have been
unwilling to review decisions of the executive related to national security, or have made a strong
presumption that the material at issue is potentially damaging.107 Still, judges have recognized
that the government must make some showing that the release of specific national defense
information has the potential of harming U.S. interests, lest the Espionage Act become a means to
punish whistle-blowers who reveal information that poses more of a danger of embarrassing
public officials than of endangering national security.108
The Supreme Court seems satisfied that national security is a vital interest sufficient to justify
some intrusion into activities that would otherwise be protected by the First Amendment—at least
with respect to federal employees. Although the Court has not held that government classification
of material is sufficient to show that its release is damaging to the national security,109 it has
seemed to accept without much discussion the government’s assertion that the material in
question is damaging. It is unlikely that a defendant’s bare assertion that information poses no
danger to U.S. national security will be persuasive without some convincing evidence to that
effect, or proof that the information is not closely guarded by the government.110
A challenge to the Espionage Act has reached the Supreme Court for decision in only one
instance. In Gorin v. United States,111 the Court upheld portions of the act now codified as 18
U.S.C. §§ 793 and 794 against assertions of vagueness, but only because jury instructions

properly established the elements of the crimes, including the scienter requirement (proof of
“guilty knowledge”) and a definition of “national defense” that includes potential damage in case
of unauthorized release of protected information and materials. Gorin was a “classic case” of
espionage, and did not involve a challenge based on the First Amendment right to free speech.
The Court agreed with the government that the term “national defense” was not vague; it was
satisfied that the term describes “a generic concept of broad connotations, referring to the military
and naval establishments and the related activities of national preparedness.”112 Whether
information was “related to the national defense” was a question for the jury to decide,113 based
on its determination that the information “may relate or pertain to the usefulness, efficiency or
availability of any of the above places, instrumentalities or things for the defense of the United
States of America. The connection must not be a strained one nor an arbitrary one. The
relationship must be reasonable and direct.”114 As long as the jury was properly instructed that
only information likely to cause damage meets the definition of information “related to the
national defense” for the purpose of the statute, the term was not unconstitutionally vague.
United States v. Morison115 is significant in that it represents the first case in which a person was
convicted for selling classified documents to the media.116 Samuel Loring Morison, charged with
providing classified satellite photographs to the British defense periodical Jane’s Defence Weekly,
argued that the espionage statutes did not apply to his conduct because he could not have had the
requisite intent to commit espionage. The Fourth Circuit rejected his appeal, finding the intent to
sell photographs that he clearly knew to be classified sufficient to satisfy the scienter requirement
under 18 U.S.C. § 793(d) (disclosure by lawful possessor of defense information to one not
entitled to receive it). The definition of “relating to the national defense” was not overbroad
because the jury had been instructed that the government had the burden of showing that the
information was so related.117 His assertedly laudable motive in permitting publication of the
photographs did not negate the element of intent.118
The fact that the Morison prosecution involved a leak to the media with no obvious intent to
transmit sensitive information to hostile intelligence services did not persuade the jury or the
judges involved that he lacked culpability, but the Justice Department did come under some
criticism on the basis that such prosecutions are so rare as to amount to a selective prosecution in
his case, and that it raised concerns about the chilling effect such prosecutions could have on

would-be whistle-blowers who could provide information embarrassing to the government but
vital to public discourse.119 On leaving office, President Clinton pardoned Morison.120
As far as the possible prosecution of the publisher of information leaked by a government
employee is concerned, the most relevant case is likely to be the Pentagon Papers case.121 To be
sure, the case involved an injunction against publication rather than a prosecution for having
published information, but the rationale for protecting such disclosure may nevertheless inform
any decision involving a conviction. In a per curiam opinion accompanied by nine concurring or
dissenting opinions, the U.S. Supreme Court refused to grant the government’s request for an
injunction to prevent the New York Times and the Washington Post from printing a classified
study of the U.S. involvement in Vietnam. The Court explained:
prior restraints are the most serious and least tolerable infringement on First Amendment
rights.... A prior restraint, ... by definition, has an immediate and irreversible sanction. If it
can be said that a threat of criminal or civil sanctions after publication “chills” speech, prior
restraint “freezes” it at least for the time. The damage can be particularly great when the
prior restraint falls upon the communication of news and commentary on current events.122
A majority of the justices suggested in separate dicta that the newspapers—along with the former
government employee who leaked the documents to the press—could be prosecuted under the
Espionage Act.123 Still, in later cases the Court stressed that any prosecution of a publisher for
what has already been printed would have to overcome only slightly less insurmountable
hurdles.124 Moreover, if national security interests were not sufficient to outweigh the First
Amendment principles implicated in the prior restraint of pure speech related to the public
interest, as in the Pentagon Papers case,125 it is difficult to discern an obvious rationale for
finding that punishing that same speech after it has already been disseminated nevertheless tilts
the balance in favor of the government’s interest in protecting sensitive information.

Criminal Prohibitions on the Publication of Classified Defense Information

The publication of truthful information that is lawfully acquired enjoys considerable First
Amendment protection.126 The Court has not resolved the question “whether, in cases where
information has been acquired unlawfully by a newspaper or by a source, government may ever
punish not only the unlawful acquisition, but the ensuing publication as well.”127 (The Pentagon
Papers
Court did not consider whether the newspapers’ receipt of the classified document was in
itself unlawful, although it appeared to accept that the documents had been unlawfully taken from
the government by their source).
The Court has established that “routine newsgathering” is presumptively lawful acquisition, the
fruits of which may be published without fear of government retribution.128 However, what
constitutes “routine newsgathering” has not been further elucidated. In the 2001 case Bartnicki v.
Vopper
, the Court cited the Pentagon Papers case to hold that media organizations cannot be
punished (albeit in the context of civil damages) for divulging information on the basis that it had
been obtained unlawfully by a third party.129 The holding suggests that recipients of unlawfully
disclosed information cannot be considered to have obtained such material unlawfully based
solely on their knowledge (or “reason to know”) that the discloser acted unlawfully. Under such
circumstances, disclosure of the information by the innocent recipient would be covered by the
First Amendment, although a wrongful disclosure by a person in violation of an obligation of trust
would receive no First Amendment protection, regardless of whether the information was
obtained lawfully.130
Bartnicki had to do with the disclosure of illegally intercepted communications in violation of
federal and state wiretap laws, which prohibited disclosure of such information by anyone who
knew or had reason to know that it was the product of an unlawful interception, but did not
prohibit the receipt of such information. The Espionage Act, by contrast, does expressly prohibit
the receipt of any national defense material with knowledge or reason to believe that it “is to be
used to the injury of the United States, or to the advantage of any foreign nation” and that it was
disclosed contrary to the provisions of the Espionage Act.131 This distinction could possibly affect
whether a court would view the information as having been lawfully acquired; although the
Bartnicki opinion seems to establish that knowledge that the information was unlawfully
disclosed by the initial leaker cannot by itself make receipt or subsequent publication unlawful, it
does not directly address whether knowledge of the nature of the information received would
bring about a different result.

Criminal Prohibitions on the Publication of Classified Defense Information

Prior Legislative Efforts
The current laws protecting classified information have been criticized as a patchwork of mostly
outdated provisions that are vague and inconsistent, or that they may not cover all the information
the government legitimately needs to protect.132 Conversely, others argue that they fail to take due
consideration of the value of releasing to the public information that the government would prefer
to keep out of view.133
The Classified Information Protection Act of 2001
In 2000, and again in 2001-2002, Congress sought to create 18 U.S.C. § 798A, subsection (a) of
which would have read:
Whoever, being an officer or employee of the United States, a former or retired officer or
employee of the United States, any other person with authorized access to classified
information, or any other person formerly with authorized access to classified information,
knowingly and willfully discloses, or attempts to disclose, any classified information
acquired as a result of such person’s authorized access to classified information to a person
(other than an officer or employee of the United States) who is not authorized access to such
classified information, knowing that the person is not authorized access to such classified
information, shall be fined under this title, imprisoned not more than 3 years, or both.134
The proposed provision would have penalized the disclosure of any material designated as
classified for any reason related to national security, regardless of whether the violator intended
that the information be delivered to and used by foreign agents (in contrast to 50 U.S.C. § 783). It
would have been the first law to penalize disclosure of information to entities other than foreign
governments or their equivalent solely because it is classified, without a more specific definition
of the type of information covered.135 In short, the provision would have made it a crime to
disclose or attempt to disclose classified information136 to any person who does not have
authorized access to such information, with exceptions covering disclosures to Article III courts,
or to the Senate or House committees or members, and for authorized disclosures to persons

accomplice liability); H.R. 6057, 95th Cong.; H.R. 13602, 94th Cong.
135 18 USCS § 1924 prohibits removal of government-owned or controlled classified information by a government
employee without authorization. 50 U.S.C. § 783 covers only information classified by the President or an executive
agency transmitted by a government employee to a foreign government. 18 U.S.C. §§ 793 and 794 are potentially
broader than these in that they cover information “related to the national defense,” by government employees and
others without regard to the identity of the recipient of the information, but these require intent or knowledge regarding
harm to the national defense.
136 “Classified information” was defined in the proposed measure to mean “information or material designated and
clearly marked or represented, or that the person knows or has reason to believe has been determined by appropriate
authorities, pursuant to the provisions of a statute or Executive Order, as requiring protection against unauthorized
disclosure for reasons of national security.”

acting on behalf of a foreign power (including an international organization). The provision
would have amended the espionage laws in title 18 by expanding the scope of information they
cover. The proposed language was intended to make it easier for the government to prosecute
unauthorized disclosures of classified information, or “leaks” of information that might not
amount to a violation of current statutes. The language was intended to ease the government’s
burden of proof in such cases by eliminating the need “to prove that damage to the national
security has or will result from the unauthorized disclosure,”137 substituting a requirement to
show that the unauthorized disclosure was of information that “is or has been properly classified”
under a statute or executive order.
The 106th Congress passed the measure as part of the Intelligence Authorization Act for Fiscal
Year 2001,138 but President Clinton vetoed it, calling it “well-intentioned” as an effort to deal with
legitimate concerns about the damage caused by unauthorized disclosures, but “badly flawed” in
that it was “overbroad” and posed a risk of “unnecessarily chill[ing] legitimate activities that are
at the heart of a democracy.”139 President Clinton explained his view that:
[a] desire to avoid the risk that their good faith choice of words—their exercise of
judgment—could become the subject of a criminal referral for prosecution might discourage
Government officials from engaging even in appropriate public discussion, press briefings,
or other legitimate official activities. Similarly, the legislation may unduly restrain the ability
of former Government officials to teach, write, or engage in any activity aimed at building
public understanding of complex issues. Incurring such risks is unnecessary and
inappropriate in a society built on freedom of expression and the consent of the governed and
is particularly inadvisable in a context in which the range of classified materials is so
extensive. In such circumstances, this criminal provision would, in my view, create an undue
chilling effect.140
The 107th Congress considered passing an identical provision,141 but instead directed the Attorney
General and heads of other departments to undertake a review of the current protections against
the unauthorized disclosure of classified information, and to issue a report recommending
legislative or administrative actions.142 An identical measure was introduced late in the 109th
Congress, but was not reported out of committee.143
The Attorney General, in his report to the 108th Congress, concluded that:
[a]lthough there is no single statute that provides criminal penalties for all types of
unauthorized disclosures of classified information, unauthorized disclosures of classified
information fall within the scope of various current statutory criminal prohibitions. It must be
acknowledged that there is no comprehensive statute that provides criminal penalties for the
unauthorized disclosure of classified information irrespective of the type of information or
recipient involved. Given the nature of unauthorized disclosures of classified information

that have occurred, however, I conclude that current statutes provide a legal basis to
prosecute those who engage in unauthorized disclosures, if they can be identified. It may be
that carefully drafted legislation specifically tailored to unauthorized disclosures of classified
information generally, rather than to espionage, could enhance our investigative efforts. The
extent to which such a provision would yield any practical additional benefits to the
government in terms of improving our ability to identify those who engage in unauthorized
disclosures of classified information or deterring such activity is unclear, however.144
Post WikiLeaks Measures
Several bills were introduced just prior to the close of the 111th Congress to address disclosures of
classified information of the type at issue in the WikiLeaks publications. The Securing Human
Intelligence and Enforcing Lawful Dissemination Act (“SHIELD Act”), S. 4004, introduced by
Senator Ensign on December 2, 2010, and a companion bill in the House, H.R. 6506, would have
amended 18 U.S.C. § 798 to add coverage for disclosures of classified information related to
human intelligence activities (the provision currently covers only certain information related to
communications intelligence). The bills would have added “transnational threat” to the entities
whose benefit from unlawful disclosures would make such disclosure illegal. The statute as
written prohibits disclosure of classified information for the benefit of any foreign government
(or to the detriment of the United States, which would remain unchanged if the bill is enacted). A
“transnational threat” for purposes of the bills means any ‘‘any transnational activity (including
international terrorism, narcotics trafficking, the proliferation of weapons of mass destruction and
the delivery systems for such weapons, and organized crime) that threatens the national security
of the United States” or any person or group who engages in any of these activities. This change
was likely intended to ensure that disclosures of any covered information that a violator
“publishes, or uses in any manner … for the benefit” of Al Qaeda or any other terrorist group,
international drug cartels, arms dealers who traffic in weapons of mass destruction, and other
international criminals will be subject to prosecution, regardless of whether the group purports to
govern any territory. As is currently the case, it is unclear whether this conduct must be
undertaken “knowingly and willfully” to incur a punishment, or whether those qualifiers apply
only to furnishing covered information to an unauthorized individual.
The bills would have added two types of information to be covered by the prohibition:
“information concerning the human intelligence activities of the United States or any foreign
government”; and “information concerning the identity of a classified source or informant of an
element of the intelligence community of the United States.” “Human intelligence” was defined
under the bill as “all procedures, sources, and methods employed in the collection of intelligence
through human sources.” “Classified information” would have been defined, as in the current
provision, as “information which, at the time of a violation of this section, is, for reasons of
national security, specifically designated by a United States Government Agency for limited or
restricted dissemination or distribution.” In other words, the information need not be classified
information within the meaning of the executive order, so long as it has been specifically
designated as subject to some form of restricted dissemination due to national security concerns.
Because the concept of national security includes foreign affairs as well as national defense, the
information covered may already be broader than that already protected under the preceding
sections of the Espionage Act. However, the proposed limitation on the identity of informants and
sources to those giving information to an element of the intelligence community may be

interpreted to exclude informants and sources who provide information to entities not listed in 50
U.S.C. § 401a(4), such as infantry units or consular offices.
Senator Cardin introduced the Espionage Statutes Modernization Act of 2010, S. 4051 (111th
Cong.) on December 21, 2010. This bill would have broadened the Espionage Act provisions by
extending their coverage to all classified information related to the national security (rather than
merely national defense information) and would have incorporated non-state threats into the
prohibition by substituting “foreign power” (as defined under the Foreign Intelligence
Surveillance Act, at 50 U.S.C. § 1801) for “foreign government” or “foreign nation.” The bill also
included a new provision to be codified at 18 U.S.C. § 1925 to prohibit the intentional
unauthorized disclosure of properly classified information by government employees, contractors,
or consultants in violation of the terms of a nondisclosure agreement. Extraterritorial jurisdiction
would have been available over U.S. nationals, permanent resident aliens, stateless persons
habitually resident in the United States, any offender who is later brought into or found in the
United States, or anyone who aids, abets or conspires with a person over whom jurisdiction
exists.
Conclusion
The Espionage Act on its face applies to the receipt and unauthorized dissemination of national
defense information, which has been interpreted broadly to cover closely held government
materials related to U.S. military operations, facilities, and personnel. It has been interpreted to
cover the activities of foreign nationals overseas, at least when they take an active part in seeking
out information. Although cases involving disclosures of classified information to the press have
been rare, it seems clear that courts have regarded such disclosures by government employees to
be conduct that enjoys no First Amendment protection, regardless of the motives of the divulger
or the value the release of such information might impart to public discourse.145 The Supreme
Court has stated, however, that the question remains open whether the publication of unlawfully
obtained information by the media can be punished consistent with the First Amendment. Thus,
although unlawful acquisition of information might be subject to criminal prosecution with few
First Amendment implications, the publication of that information remains protected. Whether the
publication of national security information can be punished likely turns on the value of the
information to the public weighed against the likelihood of identifiable harm to the national
security, arguably a more difficult case for prosecutors to make.


145 The courts have permitted government agencies to enjoin their employees and former employees from publishing
information they learned on the job, United States v. Marchetti, 466 F.2d 1309 (4th Cir.), cert. denied, 409 U.S. 1063
(1972), and permitted harsh sanctions against employees who publish even unclassified information in violation of an
obligation to obtain pre-publication clearance, Snepp v. United States, 444 U.S. 507 (1980).
