A day late and four deaths after rioters overtook the U.S. Capitol, the Army announced on Thursday the authorization of 6,200 National Guard members from seven states to support law enforcement in Washington, D.C.

“Yesterday was a horrible and shameful day in our history,” Army Secretary Ryan McCarthy said at a press conference, hosted by Washington Mayor Muriel Bowser, while praising the mayor’s and the Metropolitan Police Department’s leadership in regaining control of the Capitol after Capitol Police were overcome by supporters of President Trump who were protesting the election results.
