The sergeant at arms can, upon orders of the Senate, arrest and detain any person who violates Senate rules.[3]
The sergeant at arms is also the executive officer for the Senate and provides senators with computers, equipment, and repair and security services.[4]
The main office of the sergeant at arms is in the Postal Square Building in Washington, D.C. The core computer operations are in that building, and the staff manage Internet and intranet connections to offices of senators both in the Capitol complex and back in their home states.
