Capitol Police Chief Thomas Manger retires Friday, after rebuilding department in wake of Capitol riot

U.S. Capitol Police Chief Thomas Manger, who took charge of the department in the difficult months after the U.S. Capitol siege, is retiring from his position Friday. After the Jan. 6, 2021, Capitol riot, he helped rebuild the department's shrunken staff, beefed up recruitment efforts and bolstered the agency's intelligence operations and communications to fix weaknesses revealed by the breach of the Capitol.

Manger told CBS News he faced stiff challenges when he arrived on the job in 2021.

"The department as a whole had lost confidence in the (prior) leadership as a result of what happened," he said. "And there were big things that were identified as things that needed to be fixed as quickly as we could fix them: Things like the intelligence failures, the communication failures, the equipment failures, the training failures, the leadership failures — all of those things needed to be addressed immediately."
