advisory and liaison functions for congressional travel. The primary 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 , with about being the Capitol grounds themselves. The U.S. Capitol Police has also concurrent jurisdiction with the District of Columbia's Metropolitan Police Department (MPD), the U.S. Park Police, the U.S. Secret Service Uniformed Division, and others federal agencies to enforce District of Columbia laws, based upon cooperative agreements with MPD and the Police Coordination Act covering local cooperation with 32 federal law enforcement agencies. The U.S. Capitol Police also have extended jurisdiction over parts of Northeast, Northwest, and Southwest Washington D.C. The USCP provides protection detail to House and Senate leaders, other congressmen and -women 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. Four congressional committees have statutory oversight. The authority of the Police Chief is, in many ways, restrained. The Capitol Police chief reports to the Capitol Police Board, a three-person group composed of the Senate and House Sergeants at Arms and the Architect of the Capitol. The chief is “whipsawed between partisan politicians and career professionals like the two Sergeants at Arms and congressional staff...here they literally have hundreds of people who think they're their bosses." The pay for the USCP Chief is far less than many police chiefs in the US. In FY 2021, the USCP had an annual budget of more than $515million; it employs more than 2,000 sworn and civilian personnel, making it one of the most well-funded and well-staffed police departments relative to the two square miles it guards. USCP's budget is divided into a salaries account, used for overtime and benefits, and a general expenses account, used for equipment, vehicles, communications, training, medical services, forensic services, etc. USCP cannot transfer money between the accounts without the approval the House and Senate Appropriations Committees. In FY 2022, USCP's annual budget was $602 million. In FY 2023, USCP's annual budget will increase to $708 million to provide resources to fulfill security recommendations as suggested by the Government Accountability Office and the Office of Inspector General after the January 6th attacks on the Capitol.
