Pentagon: National Guard Deployment at US Capitol to End The U.S. Department of Defense confirmed Wednesday that the National Guard mission that was set up following the Jan. 6 Capitol breach will be discontinued on Sunday, May 23. Pentagon spokesman John Kirby told reporters during a briefing at the Pentagon that the deployment is expected to wrap up by that date. “We have received no request to extend it,” he said, referring to the National Guard deployment around the Capitol and Washington. He also said that around 2,100 National Guard troops remain around the Capitol. Secretary of Defense Lloyd Austin in March had received a request from the Capitol Police to extend the Guard’s deployment until May 23, which was approved.
