For some context, there is a mission to nationalize police. Reported by The Hill in part:

U.S. Capitol Police (USCP) on Tuesday announced that it is opening regional field offices in California and Florida to investigate threats to members of Congress as it detailed measures to enhance security efforts in the wake of deadly rioting in January.

“It has been six months since rioters attacked the United States Capitol and our brave police officers and law enforcement partners who fought valiantly to protect elected leaders and the democratic process,” Acting USCP Chief Yogananda Pittman said in a statement.

Oversight

The United States Capitol Police (USCP) is overseen by the Capitol Police Board and has Congressional oversight by appropriations and authorizing committees from the U.S. House of Representatives and the U.S. Senate. This oversight affords the department the support and opportunity to continually ensure that the USCP meets the safety and security needs of the Congress, the staff, and the many visitors who come to the United States Capitol each day.

Capitol Police Board

• Karen H. Gibson, United States Senate Sergeant at Arms (Chair)
• William J. Walker, U.S. House of Representatives Sergeant at Arms (Member)
• J. Brett Blanton, Architect of the Capitol (Member)
• Yogananda D. Pittman, Acting Chief of Police (Ex-Officio Member)
