The United States Capitol Police (USCP) is a federal law enforcement agency in the United States charged with protecting the United States Congress within the District of Columbia and throughout the United States and its territories. It answers to the Capitol Police Board and is the only full-service federal law enforcement agency appointed by the legislative branch of the federal government of the United States.
The United States Capitol Police has the primary responsibility for protecting life and property, preventing, detecting, and investigating criminal acts, and enforcing traffic regulations throughout a complex of congressional buildings, parks, and thoroughfares. The Capitol Police has primary jurisdiction within buildings and grounds of the United States Capitol Complex. It also has concurrent jurisdiction with other law enforcement agencies, including the United States Park Police and the Metropolitan Police Department of the District of Columbia, in an area of approximately 200 blocks around the complex. Officers also have jurisdiction throughout the District of Columbia to take enforcement action when they observe or are made aware of crimes of violence while on official duties. Additionally, they are charged with the protection of members of Congress, officers of Congress, and their families throughout the entire United States, its territories and possessions, and the District of Columbia. While performing protective functions, the Capitol Police have jurisdiction throughout the entire United States.[3]
Jurisdiction and budget
The jurisdiction of the United States Capitol Police centers on the United States Capitol building in Washington, D.C., the adjacent congressional (House and Senate) offices, and the Library of Congress buildings. This primary jurisdiction is about 270 acres (0.42 sq mi; 1.1 km2), with about 58 acres (0.091 sq mi; 0.23 km2) being the Capitol grounds themselves.[4] The U.S. Capitol Police also have extended jurisdiction over parts of Northeast, Northwest, and Southwest Washington D.C.[5] The USCP protects House and Senate leaders, other congresspeople depending on individual risk analysis, lawmakers' state and district offices (with the help of local police), and "off-campus" events such as presidential nominating conventions.[2]
History
The history of the United States Capitol Police dates back to 1801 when Congress moved from the city of Philadelphia to the newly constructed Capitol Building in Washington, D.C. At the time, Congress appointed one watchman to protect the building and Congressional property.
The police were formally created by Congress in 1828 following the assault on John Adams II, the son of John Quincy Adams, in the Capitol rotunda. The United States Capitol Police had as its original duty the provision of security for the United States Capitol.[10]
Its mission has expanded to provide the congressional community and its visitors with a variety of security services. These services are provided through the use of a variety of specialty support units, a network of foot and vehicular patrols, fixed posts, a full-time Containment and Emergency Response Team (CERT), K-9, a Patrol/Mobile Response Division and a full-time Hazardous Devices and Hazardous Materials Sections.[11][12]
In 1979, the Capitol Police got a separate chief of police; the role had previously been filled by officers of the Metropolitan Police Department.[13][14]
In 2005 Congress established the United States Capitol Police (USCP) Office of Inspector General (OIG) as a legislative agency. The Inspector General heads OIG, supervises and conducts audits, inspections, and investigations involving USCP programs, functions, systems, and operations, and reports directly to the Capitol Police Board.[15]
The Library of Congress Police were merged into the force in 2009.[16][17]
The Sergeant at Arms of the U.S. House of Representatives is a member of the Capitol Police Board and reports to the Speaker of the House.
Prior to 2021, four Capitol police officers had died in the line of duty.[18]
