Pence, Not Trump, Gave Order to Activate National Guard: Report

After an hours-long delay, 150 D.C. National Guard troops were sent to the U.S. Capitol to help law-enforcement efforts to remove Trump supporters who had violently seized the building in an act of insurrection. Such an order would usually be given by the president and commander-in-chief, but according to Pentagon officials who spoke with the New York Times, it was approved by Vice-President Mike Pence.
