Title 2 › Chapter CHAPTER 29— - CAPITOL POLICE › Subchapter SUBCHAPTER II— - POWERS AND DUTIES › § 1961

Last updated Apr 6, 2026|Official source

Summary

Capitol Police must police the United States Capitol Buildings and Grounds under the Capitol Police Board, made up of the Sergeant at Arms of the Senate, the Sergeant at Arms of the House, and the Architect of the Capitol. They can enforce rules tied to sections 1922, 1966, 1967, and 1969 of Title 2 and chapter 51 of Title 40, and they can arrest people on Capitol property for violations of federal, D.C., or state laws or related regulations. For the fiscal year covered by the Act that funded them, they also have authority to arrest in the District of Columbia for crimes of violence (as defined in section 16 of Title 18) that happen on Capitol property, and to make warrantless arrests for such violent crimes if the crime happens in front of a Capitol Police officer doing official work. The Metropolitan Police of D.C. may also make arrests on Capitol property, but they may not enter buildings to respond to complaints, serve warrants, or patrol there without the Capitol Police Board’s consent or request. “Grounds” includes House Office Buildings parking and property in D.C. acquired for the Senate, House, or Architect of the Capitol. It also covers buildings the Senate Sergeant at Arms or the House Chief Administrative Officer acquires and formally assigns to the Capitol Police for policing. Library of Congress buildings described in section 167j are included; if those buildings are outside D.C., the local police there get the Metropolitan Police’s authority.
