Former President Donald Trump asked “for troops around the Capitol to make sure everyone is safe,” on Jan. 6, 2021, but was “turned down by the Democrats.”

There is no record of former President Donald Trump authorizing or requesting thousands of National Guard troops for the U.S. Capitol on Jan. 6, 2021.

Several Trump administration officials who have testified before the House select committee investigating Jan. 6 said they never heard Trump request National Guard support before or during the attack.

Congressional Democrats did not deny a request for troops. The D.C. National Guard reports only to the president. If such a request had been made, they would not have had the authority to deny it.
