District Court Nominations (1917-Present)
Barry J. McMillion
The blue slip process used by the Senate Judiciary Committee for U.S. circuit and
Analyst in American
district court nominations is of ongoing interest to Congress. Since at least 1917, the
National Government
committee’s use of the blue slip has been a feature of its consideration of such

nominations. After a President selects a nominee for a U.S. circuit or district court
judgeship, the chairman sends a blue-colored form to the two Senators representing the

home state of the nominee. The form seeks the home state Senators’ assessment of the nominee. If a home state
Senator has no objection to a nominee, the blue slip is returned to the chairman with a positive response. If,
however, a home state Senator objects to a nominee, the blue slip is either withheld or returned with a negative
response. For the purposes of this report, any instance of a blue slip being withheld is treated the same as if a blue
slip were returned with a negative response—that is, both instances indicate a nominee lacked the support of at
least one home state Senator.
Since the use of blue slips is not codified or included in the committee’s rules, the chairman of the committee has
the discretion to determine the extent to which a home state Senator’s negative or withheld blue slip stops a
President’s judicial nomination from receiving consideration by the committee and, consequently, whether it
reaches the Senate floor.
During some years, a chairman has required a nominee to receive positive blue slips from both of his or her home
state Senators in order for the committee to consider the nomination. This particular blue slip policy, for example,
was in place during the entirety of the Obama presidency and much of the George W. Bush presidency.
During other years, a chairman’s blue slip policy has allowed for a nomination to proceed in committee—and, at
times, to the Senate floor—even if a nominee did not have the support of one or both home state Senators.
Regardless of the blue slip policy used by a chairman, it was nonetheless relatively rare, at least from 1956 to
2016, for the Senate to confirm a nominee who did not have the support of both home state Senators. For
example, during this 61-year period, CRS has identified three known nominees who were confirmed without such
support.
Historically, the committee’s blue slip policy applied in the same way to both U.S. circuit and district court
nominations. Senators, however, have historically exerted less influence over a President’s selection of circuit
court nominees than over district court nominees. Despite having less influence over the selection of such
nominees, home state Senators often retained certain prerogatives under the committee’s blue slip policy once a
circuit court nominee was selected by a President. For example, from 2005 through 2016, a circuit court
nomination did not proceed in committee unless it received two positive blue slips from a nominee’s home state
Senators.
The blue slip policy for U.S. circuit court nominees that had been in place during the Obama presidency and much
of the George W. Bush presidency was changed in 2017 during the 115th Congress. That policy, which has
remained in effect to the present, no longer requires a circuit court nominee to receive two positive blue slips from
his or her home state Senators in order to be considered by the Senate Judiciary Committee.
The blue slip policy for district court nominees was not changed in 2017 and has not, as of this writing, been
changed from the past practice of requiring such nominees to have the support of his or her home state Senators.

The Blue Slip Process for U.S. Circuit and District Court Nominations (1917-Present)

Introduction
The blue-slip process for U.S. circuit and district court nominations refers to a practice by the
Senate Judiciary Committee for use in the confirmation of federal judges and other positions.1
Specifically, when a President nominates an individual to a U.S. circuit or district court judgeship,
the chairman of the committee sends a blue-colored form to the Senators representing the home
state of the nominee.2 If a home state Senator has no objection to a nominee, he or she returns the
blue slip with a positive response. If, however, a Senator has some objection to the nominee and
wants to prevent confirmation, he or she might decide not to return the blue slip or to return it
with a negative response.3
There have been relatively recent years when a negative (or unreturned) blue slip precluded
Judiciary Committee action on a nomination and, consequently, the nomination was not
considered by the full Senate. This policy, for example, characterizes how blue slips were used
during the entirety of the Obama presidency (2009-2016) and much of the George W. Bush
presidency (2001-2002 and 2005-2008).4 These years during the Obama and Bush presidencies
included both unified and divided party control.5 The policy also characterizes how blue slips
were used for judicial nominations during the chairmanship of Senator James O. Eastland for the
22-year period from 1956 through 1978.
However, there were other years prior to 2017 during which the committee’s blue slip policy did
not preclude committee action on a judicial nomination that did not have the support of both
home state Senators (e.g., 2003-2004 during the Bush presidency).
Regardless of the committee’s blue slip policy during a particular Congress, it was nonetheless
relatively rare, at least from 1956 through 2016, for the Senate to confirm a judicial nominee who
did not have the support of both home state Senators. For example, during this 61-year period,
CRS has identified three known nominees who were confirmed without such support.
The blue slip policy for U.S. circuit court nominees that had been in place during the Obama
presidency and much of the George W. Bush presidency was changed in 2017 during the 115th
Congress. The revised policy, which has remained in effect to the present, no longer requires a
circuit court nominee to receive two positive blue slips from his or her home state Senators in
order to be considered by the Senate Judiciary Committee.

1 These other positions are U.S. attorney and U.S. marshal positions, which are not addressed by this report.
2 Throughout this report, these Senators are referred to as a nominee’s “home state Senators.”
3 Occasionally, a Senator might indicate on the blue slip that he or she has “reserved judgment” on a nomination. The
blue slip policy set by the chairman of the Judiciary Committee determines whether the committee will act on such a
nomination.
4 For the purposes of this report and unless otherwise noted, the date range from a presidency is shown as the period of
time that begins in the calendar year when a President takes the oath of office and concludes during his last full
calendar year in office (to more closely reflect the last year in which a President’s judicial nominees are typically
approved). So, for example and unless otherwise noted, the Obama presidency refers to the period from 2009 to 2016
(rather than the more exact period from January 20, 2009, to January 19, 2017).
5 As discussed in this report, unified party control occurs when the party of the President is the same as the majority
party in the Senate (regardless of the majority party in the House). Divided party control occurs when the party of the
President is different than the majority party in the Senate.

The policy adopted in 2017 by Senator Chuck Grassley has remained in effect to the present,
under the chairmanships of both Senator Lindsey Graham (2019-2021) and Senator Dick Durbin
(2021-present).6
The blue slip policy for district court nominees was not changed in 2017 and has not, as of this
writing, been changed from the past practice of requiring such nominees to have the support of
their home state Senators.
The blue slip process is not codified in the Judiciary Committee’s rules, and is instead a policy set
by the chairman of the committee. At times, a chair’s blue slip policy “may be different in
practice than what is stated [by the chair]. Thus, determining a particular policy at any given time
can be complicated because of the way blue slips are implemented.”7 Along these lines, this
report relies on Senators’ statements and public news accounts as to the blue slip policy that was
in place during a particular year or presidency.
Additionally, because historical data regarding whether home state Senators returned negative or
positive blue slips (or withheld a blue slip) are not often made public, the information and
analysis provided in this report are limited to the information that is publicly available regarding
blue slips returned or withheld by Senators.8
For the purposes of this report, any instance of a blue slip being withheld is treated the same as if
a blue slip were returned with a negative response—that is, both instances indicate a nominee
lacked the support of at least one home state Senator.
Origin of the Blue Slip for Judicial Nominations
Prior CRS research conducted at the National Archives identified the first known use of the blue
slip as having occurred during the 65th Congress (1917-1918).9 At the time, Senator Charles
Culberson of Texas was chairman of the Judiciary Committee, a role he served in from the 63rd
through the 66th Congress. Historical records from this time period suggest that Senator
Culberson himself may have first implemented the blue slip for judicial nominees—from the 65th
Congress onward nearly every judicial nominee’s file includes a blue slip, whereas prior to this
period, the files of judicial nominees reveal no evidence of blue slips.10
Materials at the National Archives do not provide a specific explanation for the creation of the
blue slip. However, the historical and political context in which the blue slip was first used might
help illuminate the rationale for its early use. For instance, in 1917, although the White House
and Senate were both controlled by the Democratic Party, there was periodic tension between the

Durbin’s chairmanship corresponds to the 117th Congress (January 3, 2021, to January 3, 2023) and the 118th Congress
(January 3, 2023, to the present).

the Presidency, vol. 37, 2010, p. 130 (hereinafter cited as Sollenberger, “The Blue Slip”).
8 A recent exception to this generalization occurred during select years of the G.W. Bush presidency. Specifically, from
2001 to 2004, the status of a nominee’s blue slips was posted online by the Department of Justice’s Office of Legal
Policy.

two branches. Consequently, interbranch relations may have been a factor in the blue slip’s
creation.11
The first known example of a Senator using a blue slip to oppose a judicial nomination also
occurred in 1917. Specifically, President Woodrow Wilson had nominated U.V. Whipple to a
judgeship for the Southern District of Georgia. Senator Thomas W. Hardwick returned a negative
blue slip, stating “I object to this appointment—the same is personally offensive and
objectionable to me, and I cannot consent to the confirmation of the nominee.”12 At that time, a
negative blue slip did not necessarily prevent committee action on a nomination. As such,
Whipple’s nomination was reported, albeit adversely, to the full Senate. The nomination was
rejected by the Senate without a recorded vote on April 23, 1917.13
Presidential Consultation with Home State Senators
While the specific blue slip policy used by the Judiciary Committee has varied, a consistent
principle throughout has been the importance of consultation between a President and the Senate
in the judicial selection process. During this process, one of the key considerations of many
Senators, including committee chairmen and Senators in the minority party, is that they have the
opportunity to consult with a President regarding potential nominees for U.S. circuit and district
court vacancies associated with their states. The lack of consultation between a President and
home state Senators has, at times, resulted in nominations not being considered by the Judiciary
Committee.14
Senator Durbin, the current chairman of the Judiciary Committee, recently emphasized the
importance of a President consulting with home state Senators in the blue slip process, stating that
“many of us … believe in what’s known as the blue slip process, which basically says that
senators will have some say in terms of the judges that are chosen in their states.”15
Past committee chairmen, regardless of political party, have also emphasized the need for
consultation and interbranch cooperation between a President and home state Senators in the
consideration of potential U.S. circuit and district court nominees. In 1989, for example, then-
Senator Joe Biden stated that “I have long emphasized the need for consultation, which, in my
view, is part of the ‘advice’ component of the Senate’s advice and consent responsibility under the
Constitution. I believe that the nomination process will function more effectively if consultation
is taken seriously.”16 In 2001, Senator Hatch stated that “the Senate expects genuine good faith
consultation by the administration with home state senators before a judicial nomination is made,
and the administration’s failure to consult in genuine good faith with both home state senators is

14 For example, during several years of the Clinton presidency a number of nominations reportedly did not move
forward because of a lack of support from home state Senators. Specifically, 17 nominations reportedly lacked the
support of home state Senators, in part, because the White House did not consult with Senators regarding the
nominations. Sollenberger, “The Blue Slip,” p. 138.

grounds for a senator’s return of a negative blue slip.”17 Additionally, in 2009, Senator Leahy
noted that requiring “the support of home State Senators is a traditional mechanism to encourage
the White House to engage in meaningful consultation with the Senate.”18
The importance of consultation has also been emphasized, more generally, by other Senators. For
example, in 2009, 41 Republican Senators submitted a letter to President Obama, stating that,
Regretfully, if we are not consulted on, and approve of, a nominee from our states, the
Republican Conference will be unable to support moving forward on that nominee.19
Additionally, during the George W. Bush presidency, the nine Democratic Senators on the
Judiciary Committee submitted a letter to the Administration emphasizing the need for
consultation between the White House and Senators belonging to the minority. The letter stated
that,
As you know, there has been a long history of consultation between the White House and
the Senate on potential nominations. The Senate’s recent practice fully recognized that the
interests of Senators in judicial nominations are not limited to those in the same political
party as the President. With an evenly divided Senate, we think it is of utmost importance
that the Administration coordinate closely with Democrats in the Senate, especially those
from the home state of potential nominees and those on the Judiciary Committee.20
How Consultation, or the Lack of Consultation, Has Been Defined
in the Past
During the Clinton presidency, and a period of divided government, Senator Hatch identified five
circumstances that would “demonstrate an absence of good faith consultation” by the White
House in communicating with home state Senators.21 These circumstances were identified in a
letter to Charles Ruff, counsel to the President, and included the following:
(1) failure to give serious consideration to individuals proposed by home state Senators as
possible nominees;
(2) failure to identify to home state Senators and the Judiciary Committee an individual the
President is considering nominating with enough time to allow the Senator to provide
meaningful feedback before any formal clearance (i.e., by the [American Bar Association]
or [Federal Bureau of Investigation]) on the prospective nominee is initiated;
(3) after having identified the name of an individual the President is considering
nominating, failure to (a) seek a home state Senator’s feedback, including any objections
the Senator may have to the prospective nominee, at least two weeks before any formal
clearances are initiated, and (b) give that feedback serious consideration;
(4) failure to notify a home state Senator, and the Judiciary Committee, that formal
clearance on a prospective nominee is being initiated despite the Senator’s objections; and

17 Sollenberger, Judicial Appointments, p. 103. Note that Sen. Hatch also emphasized that “if any of our colleagues
here want to veto the President’s constitutional prerogative to make his appointments with the advice and consent of the
Senate, that is a different matter, and one which I think diverges from the policy of this Committee from as far back as I
can remember, ... ” Sen. Hatch’s assessment, one scholar notes, was challenged by Democratic Senators at the
committee hearing at which it was made. Sollenberger, “The Blue Slip,” p. 140.

(5) failure to notify home state Senators, and the Judiciary Committee, before a nomination
is actually made, that the President will nominate an individual.22
The letter released by Senator Hatch also included his rationale for identifying the five
circumstances that demonstrated an absence of good faith consultation by the White House. He
stated that “over the past several months, I have received complaints from a number of my
colleagues that they have not had the benefit of any sort of good faith consultation that is
expected with respect to judicial nominees, and I am concerned that this may lead to difficulties
in the confirmation process that could be avoided.”23
At the beginning of the George W. Bush presidency, Senator Leahy, then ranking minority
member of the Judiciary Committee, sent a letter to Alberto Gonzales, counsel to the President,
recommending that “the Administration undertake to incorporate the following consultative
procedures into its selection, vetting and nomination processes.”24 These procedures included the
following:
1. The Administration shall give serious consideration to individuals proposed by home
state Senators as possible nominees;
2. The Administration shall consult with home state Senators and the Judiciary Committee
(both majority and minority) regarding individuals the President is considering nominating
with enough time to allow Senators to consider the potential nominee and provide a
meaningful response to the Administration before any formal clearance (i.e., by the
[Federal Bureau of Investigation]) on the prospective nominee is initiated;
3. Should the Administration choose to begin a formal clearance process of a nominee
despite a home state Senator’s objection, the Administration shall notify the home state
Senators and the Judiciary Committee that this is the case before the clearance process
starts;
4. When the President has made the final decision to nominate an individual, home state
Senators and the Judiciary Committee shall be given at least one week’s notice before the
formal nomination is made;
5. When a nominee is sent to the Senate, supporting documentation for the nomination
shall be simultaneously sent to the Senate in order to expedite the Senate’s evaluation of
the nominee;
6. The nominee shall be directed by the Administration to cooperate fully with Senators
who seek information regarding that nomination.25
When Senator Leahy later became chairman of the Judiciary Committee in 2001, he had “the
opportunity to” require “these consultative procedures through a strengthened blue slip policy.”26
As discussed below, this policy—which required both home state Senators to return positive blue
slips on a nomination in order for it to be considered by the committee—was also utilized during
his time as committee chair during the Obama presidency.
Most recently, in response to opposition by home state Senators to one of President Biden’s
circuit court nominees (a nomination over which the Senators said they were not consulted),
Chairman Durbin has suggested that a rule for consultation might be appropriate following the
next presidential election. Senator Durbin stated “perhaps we can agree that prospectively after

the 2024 presidential election, there will be a rule. We don’t know who’s going to win at this
point, and we might have a standard moving forward from there.”27
Past Blue Slip Policies (1917-2016)
Years When a Negative Blue Slip on a Nomination Did Not Stop
Consideration by the Senate Judiciary Committee
From 1917 through 2016, there were years when the policy of the Judiciary Committee was to
allow, in some instances, committee consideration of a judicial nomination that had received a
negative blue slip from one or both of the nominee’s home state Senators (or had a positive one
withheld).
Consequently, when such a policy was in effect, a Senator’s negative blue slip, or failure to return
a positive slip, did not always foreclose the possibility of the committee reporting the nomination
to the Senate—as, for example, occurred on five occasions during the 108th Congress (2003-
2004).28 It likely did, however, at least draw the committee’s attention to the concerns of the
home state Senator and to the question of what degree of courtesy the members of the committee
owed that Senator’s concerns.29
1917-1955
According to prior CRS research, the blue slip was used from 1917 to 1955 “to merely request the
opinion of senators, regardless of political party, about judicial nominations in their home-
states.... [and] no chair of the Judiciary Committee allowed even one negative blue slip to
automatically veto a nomination.”30
Despite this characterization of the committee’s blue slip policy during this period, CRS has not
identified a nomination, other than U.V. Whipple’s in 1917 (as discussed above), that was acted
upon by the committee if it was opposed by at least one of the nominee’s home state Senators.
1979-1980
The blue slip policy used during the last two years of the Carter presidency, under the
chairmanship of Senator Edward Kennedy,31 no longer prevented committee action on a
nomination that was not supported by a home state Senator. Senator Kennedy altered the blue slip
policy that was used during his predecessor’s tenure (a policy that required a nominee to receive

28 The nominations reported by the Judiciary Committee were each for circuit court judgeships, and include the
nominations of Richard A. Griffin (to the Sixth Circuit), Carolyn B. Kuhl (Ninth Circuit), David McKeague (Sixth
Circuit), Susan B. Neilson (Sixth Circuit), and Henry W. Saad (Sixth Circuit).
29 Additionally, this type of blue slip policy, while occasionally allowing a nomination to advance without the support
of both home state Senators, did not lead to a relatively large number of nominations advancing in the Senate without
the support of both home state Senators.

two positive blue slips) in order to increase the gender and racial diversity among judicial
nominees.32
During the two-year period he served as chairman of the committee, Senator Kennedy moved
forward on one known nomination that had received a negative blue slip.33 The nominee received
a hearing but the committee took no additional action on his nomination. The hearing itself was
the first reported instance, since the early 1950s, where the Judiciary Committee moved forward
on a nomination that had received a negative blue slip from a home state Senator.34
1981-1986
During the first six years of the Reagan presidency, under the chairmanship of Senator Strom
Thurmond,35 judicial nominations that received negative blue slips or had blue slips withheld by
home state Senators were sometimes considered by the Judiciary Committee and, in a few cases,
by the full Senate. As is the case with the George H.W. Bush presidency (discussed below), the
total number of nominees during the Reagan presidency with negative or withheld blue slips is
unknown.
During this period, Senator Thurmond moved forward on three known nominations that had
received one negative blue slip and on one known nomination for which a home state Senator had
not returned a blue slip. Of the four, two were confirmed by the Senate.36
1989-1992
In 1989, at the beginning of the George H.W. Bush presidency—and during a period of divided
party control—Senator Biden issued the first policy letter by a Judiciary Committee chairman
regarding the use of blue slips to process U.S. circuit and district court nominations. He stated
that “The return of a negative blue slip will be a significant factor to be weighed by the committee
in its evaluation of a judicial nominee, but it will not preclude consideration of that nominee

32 Sen. Kennedy stated that he had a “particular concern ... to guarantee that the Federal courts are more representative
of all the people of this Nation.” Sollenberger, “The Blue Slip,” p. 131. Prior to the blue slip policy change in 1979,
there had been 12 women and 34 racial minorities ever appointed to U.S circuit and district court judgeships. During
Sen. Kennedy’s chairmanship, 23 women and 39 racial minorities were appointed to such judgeships.
33 Sen. Harry Byrd Jr., of Virginia, had returned a negative blue slip on the district court nomination of James E.
Sheffield. In another instance, and “the only known example of a nomination dispute between Kennedy and a
Republican Senator,” a positive blue slip on the nomination was eventually returned. Sollenberger, “The Blue Slip,” pp.
132-133.
34 Sollenberger, “The Blue Slip,” p. 132.
35 Specifically, from January 3, 1981, to January 3, 1987.
36 In 1981, Sen. Proxmire of Wisconsin returned a negative blue slip for the district court nomination of John Shabaz to
the Western District of Wisconsin. “Despite the negative blue slip, [Senator] Thurmond moved Shabaz’s nomination
through committee. This action marked the first known instance in more than thirty years in which a blue-slipped
nomination made it to the Senate floor. Once through committee, the Senate confirmed Shabaz.” Sollenberger, “The
Blue Slip,” p. 134. In 1982, Sen. Proxmire also returned a negative blue slip for the nomination of John L. Coffey to the
Seventh Circuit. The negative assessment by Proxmire “was ignored when a hearing and committee vote were held less
than a month after Reagan made the nomination.” Ibid., p. 134. Coffey was subsequently confirmed by the Senate. Also
in 1982, Sen. Thurmond held a hearing for Sam Bell, a district court nominee for the Northern District of Ohio, even
though Sen. Metzenbaum had not yet returned a blue slip on the nomination (he eventually did and Bell was confirmed
by the Senate). Ibid. Finally, in 1985, Democratic Sens. Daniel Inouye and Spark Matsunaga of Hawaii opposed the
district court nomination of Albert Moon. “Even though both Hawaiian senators opposed Moon, Thurmond held a
hearing which marked the first reported instance since the 1950s that the committee acted on a nomination with two
negative blue slips. After the hearing, Thurmond took no further action and Moon’s nomination was returned at the end
of the Congress.” Ibid.

unless the Administration has not consulted with both home state Senators prior to submitting the
nomination to the Senate.”37
While it is not known how many nominees during the George H.W. Bush presidency had blue slip
issues, there are two known examples of Senator Biden moving forward on a judicial nomination
that received a negative blue slip from a nominee’s home state Senator (in both cases from
Senator Alan Cranston). For one circuit court nomination, the committee held hearings and a
vote. The committee rejected the nomination, thereby not reporting it to the full Senate.38 And for
one district court nomination, the committee held hearings and a vote—approving the nomination
and sending it to the full Senate for consideration. The nomination was approved by voice vote.39
2003-2004
During the 2003-2004 period, the blue slip policy of Senator Hatch was to “give great weight to
negative blue slips”40 but, in some instances, to allow a nomination opposed by home state
Senators to receive a committee hearing and committee vote (which could result in the
nomination being reported to the full Senate without the support of one or both home state
Senators). During this two-year period of the George W. Bush presidency, there were 13
nominees with blue slip issues, 5 of whom received a committee hearing and committee vote.41
This particular period reflected unified party control, during which there was a Republican
President and a Republican majority in the Senate.
Years When a Negative Blue Slip on a Nomination Stopped
Consideration by the Senate Judiciary Committee
From 1956 through 2016 there were a number of years when a home state Senator’s opposition to
a judicial nomination through use of a negative or withheld blue slip prevented it from being
reported out of committee (in effect, preventing the nomination from being approved by the full
Senate), unless the Senator could be persuaded to drop his or her opposition to the nomination.
Most recently, this was the case during the entirety of the Obama presidency (2009-2016) and for
much of the G.W. Bush presidency (2001-2002 and 2005-2008).
1956-1978
From 1956 through 1978, under the chairmanship of Senator James O. Eastland of Mississippi, a
nominee was required to receive two positive blue slips from his home state Senators before the
committee would consider the nomination. These years correspond to the second session of the
84th Congress through the 95th Congress and included all or part of the Eisenhower, Kennedy,
Johnson, Nixon, Ford, and Carter presidencies.

Committee approved the Walker nomination by an 11-to-2 vote, sending the nomination to the full Senate (which
confirmed the nomination by voice vote). For more details, see Sollenberger, “The Blue Slip,” p. 136.
40 Sollenberger, “The Blue Slip,” p. 144.
41 Of the five nominees, three were later confirmed during the 109th Congress after home state Senators withdrew their
opposition to the nominations. The nominations of the two other nominees were returned to President Bush (and not
resubmitted for Senate consideration).

The Blue Slip Process for U.S. Circuit and District Court Nominations (1917-Present)

During this period, which encompassed both unified and divided party control of the presidency
and the Senate, if a home state Senator had some objection to the nominee and wanted to stop
committee action, he or she could decide not to return the blue slip or return it with a negative
response. Under such circumstances, the withholding of a blue slip or a single negative response
would halt all further action on a nomination.
1995-2000
The blue slip policy of Senator Hatch, who served as chairman of the Judiciary Committee during
the final six years of the Clinton presidency (1995-2000), enabled a home state Senator to block
committee action on a nomination by returning a negative blue slip.42 This period corresponds to
the 104th, 105th, and 106th Congresses.
During this period, 17 of President Clinton’s judicial nominations lacked the support of one or
both home state Senators.43 Consequently, the committee did not act on the nominations, with
Senator Hatch stating that the lack of support was often the result of the White House failing to
consult with home state Senators about the nominations.44
2001-2002, 2005-2006, and 2007-2008
During the George W. Bush presidency, Senator Patrick Leahy, who served as chairman of the
Judiciary Committee during 2001-2002 and 2007-2008,45 did not permit, during those two
periods, a U.S. circuit or district court nomination to advance in committee without receipt of two
positive blue slips from a nominee’s home state Senators. These years correspond to part of the
107th Congress and the entirety of the 110th Congress.
During the period from 2001 through 2002, there are 7 known nominees for whom a home state
Senator either returned a negative blue slip or withheld a blue slip (thereby stopping committee
action on the nomination).46 Additionally, from 2007 through 2008, there are 16 known nominees
for whom a home state Senator either returned a negative blue slip or withheld a blue slip.47
Additionally, from 2005-2006, when Senator Arlen Specter was chairman of the Judiciary
Committee,48 the committee did not move forward with any nomination that did not receive two
positive blue slips from a nominee’s home state Senators.49 These years correspond to the 109th
Congress.

45 Specifically, from June 6, 2001, to January 15, 2003, and from January 3, 2007, to January 3, 2009.
46 This includes 5 U.S. circuit court nominees and 2 U.S. district court nominees. Sollenberger, “The Blue Slip,” p. 142.
47 This includes 6 U.S. circuit court nominees and 10 U.S. district court nominees. Sollenberger, “The Blue Slip,” p.

48 From January 3, 2005, to January 3, 2007.
49 One senior Republican committee staffer has explained that Sen. Specter, wanting to bypass any nomination that
would experience confirmation problems, “started with the nominees who were easy to move and then just ran out of
time with the others.” The staffer also remarked that Sen. Specter sought to avoid battles over nominees opposed by
their home state Senators because “he was very concerned about moving through some of his legislative priorities,” and
that Sen. Specter “very much sees the Congress, and the Senate in particular, as an equal branch and a check on the
executive.” Additionally, Sen. Specter’s blue slip policy was probably influenced by the compromise agreement drafted
by the bipartisan “Gang of 14” regarding the use of filibusters on lower federal court nominations, as well as the need
of the Judiciary Committee to manage three Supreme Court nominations (thereby diverting resources that would
typically have been used on lower court nominations). Sollenberger, “The Blue Slip,” p. 148.

The Blue Slip Process for U.S. Circuit and District Court Nominations (1917-Present)

During the 2005-2006 period, there are 12 known nominees for whom a home state Senator either
returned a negative blue slip or withheld a blue slip (thereby stopping committee action on the
nomination).50
Of the total 37 known nominees during the Bush presidency who experienced blue slip issues
(including the tenure of Senator Orrin Hatch as committee chair for several months in 2001 and
from 2003 to 2004), 15 were ultimately confirmed after home state Senators withdrew their
opposition to the nominations.51 The remaining 22 nominees with negative or withheld blue slips,
representing approximately 6% of all individuals nominated by President Bush for either a U.S.
circuit or district court judgeship from 2001 through 2008, were subsequently returned to the
President (i.e., not confirmed).
As the chairmanships of Senators Leahy and Specter showed, the committee’s blue slip policy
was not always determined by whether the party that controlled the presidency was also the
majority party in the Senate.
2009-2016
During the eight years of the Obama presidency, the policy of both Senator Leahy (chairman of
the Judiciary Committee from 2009 to 2014) and Senator Chuck Grassley (chairman from 2015 to
2016) was to preclude consideration of a U.S. circuit or district court nomination by the
committee if the nomination did not receive two positive blue slips from the nominee’s home
state Senators.52
This eight-year period encompassed both unified party control (i.e., when Democrats controlled
the presidency and held the majority in the Senate from 2009 through 2014) and divided party
control (i.e., when Republicans held the majority in the Senate, from 2015 through 2016, during
the final two years of the Obama presidency).
From 2009 through 2014, the period of unified party control, there are 11 known nominees for
whom a home state Senator either returned a negative blue slip or withheld a blue slip (thereby
stopping committee consideration of the nomination).53 Additionally, from 2015 through 2016,
the period of divided party control, there are 9 known nominees for whom a home state Senator
either returned a negative blue slip or withheld a blue slip (similarly stopping committee
consideration of the nomination).54
Of the 20 known nominees during the Obama presidency who experienced blue slip issues, 2
were ultimately confirmed after home state Senators withdrew their opposition to the
nominations.55 The remaining 18 nominees with blue slip issues, representing approximately 5%

50 This includes 4 U.S. circuit court nominees and 8 U.S. district court nominees. Sollenberger, “The Blue Slip,” p. 147.
51 Sollenberger, “The Blue Slip,” pp. 142, 144, 147, 150. Sen. Hatch was chairman of the Judiciary Committee from
January 20, 2001, to June 5, 2001, and from January 15, 2003, to January 6, 2005. As discussed in the report, Sen.
Hatch’s blue slip policy during these years did not necessarily stop committee consideration of a nominee who failed to
receive two positive blue slips. His chairmanship is included in this part of the analysis to provide a summary of the
G.W. Bush presidency, and also because there were multiple nominees during the Bush presidency who were
considered by the Judiciary Committee under different chairmanships (i.e., under the chairmanships of Sens. Leahy,
Hatch, and/or Specter).
52 Specifically, Sen. Leahy chaired the committee from January 3, 2009, to January 3, 2015, and Sen. Grassley from
January 3, 2015, to January 3, 2017
53 This includes 3 U.S. circuit court nominees and 8 U.S. district court nominees.
54 This includes 4 U.S. circuit court nominees and 5 U.S. district court nominees.
55 The 20 nominees were identified by CRS through Senators’ statements and public news accounts. See, for example,

of all individuals nominated by President Obama for either a U.S. circuit or district court
judgeship from 2009 through 2016, were subsequently returned to the President (i.e., not
confirmed).
As the discussion about the George W. Bush and Obama presidencies illustrates, recent blue slip
policies that required positive blue slips from a nominee’s home state Senators in order for the
nomination to advance in committee did not always mean that a nominee who initially lacked the
support of one or both home state Senators was not ultimately confirmed by the Senate.56 In total,
of the 57 known nominees with blue slip issues during the Obama and George W. Bush
presidencies, 17 (or 30%) were ultimately confirmed after opposition by one or both home state
Senators was withdrawn.
The nominees who initially experienced blue slip issues during these two presidencies but who
were nonetheless later confirmed by the Senate were sometimes included as part of an agreement
or compromise between the White House and Senators to advance judicial nominations to the full
Senate for consideration.57
Years When It Is Uncertain Whether a Negative Blue Slip on a
Nomination Stopped Consideration by the Senate Judiciary
Committee
1987-1988
For the 1987-1988 period (the final two years of the Reagan presidency, when Senator Biden was
chairman of the Judiciary Committee), CRS has not identified a formal blue slip policy that was
announced by Senator Biden during these particular years. CRS has also not identified any
instances of the committee considering a nomination that was opposed by one or both home state
Senators.
As discussed above, at the beginning of the George H.W. Bush presidency in 1989, Senator Biden
explicitly stated that a negative blue slip would not necessarily stop committee consideration of a
judicial nomination.

become-federal-judge.
56 Under a blue slip policy that requires both home state Senators to return positive blue slips, a President also has the
option of withdrawing an objectionable nomination and resubmitting a new nomination that is acceptable to the White
House and both home state Senators. For example, in 2008, the last year of the G.W. Bush presidency, President Bush
in three instances—each time facing opposition from home state Senators to specific circuit court nominations—
withdrew the nominations and selected new nominees recommended by the Senators. See CRS Report RL34405, Role
of Home State Senators in the Selection of Lower Federal Court Judges, by Barry J. McMillion and Denis Steven
Rutkus, footnote 84, p. 24.

The Blue Slip Process for U.S. Circuit and District Court Nominations (1917-Present)

1993-1994
During the first two years of the Clinton presidency, CRS has not identified a formal statement by
Senator Biden about the blue slip policy he used during this period as committee chairman.
According to one scholar, “blue slips were not an issue during the first two years of Bill Clinton’s
presidency … Biden made no formal announcement changing his blue slip policy [from 1989]
and there were no major disputes over nominations.”58 Additionally, CRS has not identified any
instances of the committee considering a nomination that was opposed by one or both home state
Senators.
The Current Blue Slip Policy (2017-Present)
The blue slip policy for U.S. circuit court nominees that had been in place during the Obama
presidency and much of the George W. Bush presidency was changed in 2017 during the 115th
Congress. Senator Chuck Grassley announced that he would permit confirmation hearings for
circuit court nominees who did not have two positive blue slips from home state Senators, stating
that “circuit courts cover multiple states. There’s less reason to defer to the views of a single
state’s senator for such nominees.”59
The policy adopted in 2017 for circuit court nominations has remained in effect to the present,
under the chairmanships of both Senator Lindsey Graham (2019-2021) and Senator Dick Durbin
(2021-present).60
The policy for district court nominees was not changed in 2017 and has remained the same under
the chairmanships of Senators Graham and Durbin, with a nominee required to have two positive
blue slips from home state Senators in order for the committee to consider his or her
nomination.61
The blue slip policy for circuit and district court nominees that has been in place since 2017 is,
based on publicly available information, the first policy used by the Senate Judiciary Committee
that has explicitly treated circuit and district court nominations differently in terms of whether the
committee would consider nominations in light of opposition by one or both home state Senators.

60 This period follows, by several years, the earlier reinterpretation of Senate Rule XXII during the 113th Congress to
allow cloture to be invoked on most nominations by a majority of Senators voting (a quorum being present). See

Known Instances When a Negative Blue Slip Did
Not Stop Senate Confirmation of a Judicial
Nomination
1956-2016
From 1956 through 2016, there were over 2,500 individuals confirmed by the Senate to U.S.
circuit and district court judgeships. Despite the different blue slip policies used by chairmen of
the Judiciary Committee during this period, there are three known nominees among this group
who were confirmed by the Senate after having received a negative blue slip by one, but not both,
home state Senators. These nominees are listed in Table 1.
Based on available information, CRS has not identified any instances, from 1956 through 2016,
of a nominee who was confirmed by the Senate after having received negative blue slips from
both of his or her home state Senators.62
Similarly, CRS has not identified any instances from 1956 through 2016 when a nominee was
confirmed by the Senate after having received one negative blue slip while another blue slip was
withheld (or when both blue slips were withheld).

2017-Present
Since the blue slip policy was changed in 2017, and as of July 1, 2023, there have been a total of
21 circuit court nominees with at least one negative (or withheld) blue slip whose nominations
were considered by the Senate Judiciary Committee. Of the 21 nominees, 20 (95%) have been
confirmed by the Senate over the opposition of at least one home state Senator.63 These nominees
are listed in Table 2.
