The Capitol Police Board is the body that governs the United States Capitol Police. It was established in 1873, and today consists of three voting members: the Sergeant at Arms of the United States House of Representatives, the Sergeant at Arms of the United States Senate, and the Architect of the Capitol. Additionally, the chief of the Capitol Police serves ex officio as a non-voting member. The chairmanship of the board alternates annually between the House and Senate Sergeants at Arms.
