J. Thomas Manger, who spent 21 years as a police chief in the wealthy Washington suburbs of Montgomery and Fairfax counties, was named Thursday to take over the U.S. Capitol Police as it tries to regain its footing in the aftermath of the Jan. 6 riot at the Capitol. More than 80 Capitol officers were assaulted, two later died, and its commanders were found to have ignored warnings of a violent attack.

Manger was selected by three members of the Capitol Police Board — the sergeant-at-arms of the House and the Senate, and the architect of the Capitol — as well as top congressional leaders, who oversee the police department. He succeeds Chief Steven A. Sund, who resigned days after the insurrection amid heavy criticism of the department’s lack of preparation, and interim chief Yogananda D. Pittman, who was head of Capitol Police intelligence before Jan. 6.

“The Congress is fortunate to have a seasoned decision-maker,” the board said in a statement, “who will lead with integrity, draw on his regional experience in strengthening partnerships with law enforcement partners, and make intelligence-based security decisions.”
