Presidential Candidate and Nominating Convention Security
Introduction
Candidate and Nominee Protection
In 1968, Congress authorized U.S. Secret Service (USSS)
protection of presidential candidates following the
assassination of Democratic Party presidential candidate
Senator Robert F. Kennedy. At that time, a congressional
advisory committee (82 Stat. 170) was established to make
recommendations to the Secretary of the Treasury on which
candidates should be protected. Threats against Presidents
and presidential candidates have a long history in the
United States. Targeted presidential candidates include
Theodore Roosevelt, Robert F. Kennedy, George C.
Wallace, and Edward Kennedy. Four Presidents have been
assassinated:
Abraham Lincoln;
James A. Garfield;
William McKinley; and
John F. Kennedy (with USSS protection).
Threats to presidential candidates, presidents-elect, and
other USSS protectees typically reflect general threats to
the President. For example, fears of kidnapping and
assassination threats towards Abraham Lincoln began with
his journey to Washington, DC, for the 1861 inauguration.
The assassination of Senator Robert F. Kennedy later
spotlighted threats to those campaigning for the presidency.
The USSS does not provide information on any threats to
protectees or investigations related to threats made against
protectees. The USSS reported that the expenditures for
presidential campaign security in FY2016 was $145
million, including both candidate and nominee protection.
This amount is in addition to $100 million Congress
appropriated for the 2016 nominating conventions ($50
million each). For the 2020 nominating conventions,
Congress also has appropriated $100 million for security
(P.L. 116-93).
The USSS was officially assigned to protect Presidents in
1906. Assassination attempts (identified by the USSS and
media reports) on Presidents with USSS protection include:
Harry S. Truman;
Richard Nixon;
Gerald R. Ford;
Ronald Reagan;
William J. Clinton;
George W. Bush;
Barack Obama; and
Donald Trump.
Presidential candidate security generally includes the detail
of USSS special agents to protect the candidate and the
locations to which the candidate travels. Protection involves
related security plans and analysis of possible and actual
threats. According to the USSS, protection of candidates
occurs 24 hours a day until the protection is deemed
unnecessary, the candidate ends his or her campaign or does
not become the nominee, or the nominee does not become
the President-elect. Table 1 lists the candidates and
nominees who received USSS protection between 2000 and
2020.
The USSS was transferred to the Department of Homeland
Security in 2003. The Secretary of Homeland Security now
has the responsibility of determining which presidential
candidates are protected, following the recommendations of
the advisory committee. The committee includes the
Speaker and minority leader of the House, the Senate
majority and minority leaders, and one additional member
selected by the committee. There are two categories of
candidates who receive USSS protection: (1) candidate
protectees, who receive protection prior to receiving their
political party’s nomination; and (2) nominee protectees,
who receive protection following their party’s nomination.
The USSS is statutorily required to protect major
presidential and vice presidential candidates within 120
days of the general presidential elections, as well as their
spouses (18 U.S.C. Section §3056(a)).This In Focus
discusses protection of presidential candidates—both before
and after the party nominating conventions—and provides
an overview of funding for security operations at the
nominating conventions.

Presidential Candidate and Nominating Convention Security
In March 2020, the House Homeland Security Committee
requested that the USSS protect Democratic Party
presidential candidate Joe Biden, and a USSS spokesperson
confirmed that he was receiving USSS protection. Media
accounts state that this is the result of protesters at the
former Vice President’s campaign events.
Nominating Convention Security
Every four years, the two major political parties, and some
third parties, typically select their presidential nominees at
conventions. These conventions are run by and for the
parties, without a formal role for the federal government
other than security. Until recently, voluntary taxpayer
designations provided certain financial support to
convention committees that chose to accept public money
through the Presidential Election Campaign Fund (PECF).
Historically, the PECF provided financial assistance to
publicly financed presidential campaigns, but the PECF was
repealed in 2014 via P.L. 113-94. Separately from the
PECF funding, Congress has appropriated funding through
the Department of Justice (DOJ) for security costs incurred
by state and local governments hosting the conventions.
These security funds for the conventions are appropriated to
the Office of Justice Programs (OJP), within the DOJ. This
OJP funding, specifically through the Edward Byrne
Memorial Justice Assistance Grant program, has been
available for all major party conventions in the wake of the
September 11, 2001, terrorist attacks (see Table 2).

The $100 million Congress appropriated for the 2020
presidential nominating conventions is primarily to
reimburse states and localities for law enforcement costs
associated with their participation in securing the
convention sites. In 2004, 2008, 2012, and 2016, the main
security costs that state and local law enforcement entities
incurred involved overtime payments. State and local law
enforcement personnel participate in securing the
convention venue, and also in advance planning,
conducting liaison for venue and air space security,
training, and establishing and maintaining communications.
The USSS is responsible for planning, coordinating, and
implementing security operations at conventions. Congress
authorized the USSS—when directed by the President—to
be the lead federal agency for convention security in P.L.
106-544 (the Presidential Threat Protection Act of 2000).
The conventions are generally designated as National
Special Security Events (NSSEs), which are the purview of
the USSS. Other NSSEs include such events as presidential
inaugurations, major international summits held in the
United States, and some major sporting events.
Security costs incurred by the federal government
associated with the conventions are not paid out of the $100
million appropriated in FY2020. These other federal
security costs are covered by the $145 million appropriated
to the USSS (P.L. 116-93), which includes the USSS
protection of the major presidential candidates whether at
the convention or at other campaign locations. The USSS is
also the Lead Federal Agency for security at nominating
conventions, coordinating other federal agencies, such as
Federal Protective Service law enforcement officers, in
securing the convention sites. Federal law enforcement and
security agencies, under USSS operational control, also
oversee physical security at the convention venue through
the positioning of fencing and barricades, as well as the prepositioning of federal law enforcement K-9 units and other
teams such as the U.S. Department of Homeland Security’s
Domestic Emergency Support Teams, and Urban Search
and Rescue Teams.
