Democratic lawmakers are calling on President Donald Trump to demand that all of his supporters leave the Capitol building after they broke in to interrupt a joint session of Congress to certify the results of the U.S. presidential election.

Democratic Senate Minority Leader, Chuck Schumer said “I am calling on President Trump to demand that all protestors leave the U.S. Capitol and Capitol grounds immediately,” Democratic House Speaker Nancy Pelosi wrote on Twitter.

The U.S. Capitol building is on lockdown and the debate over whether to certify the results of the November U.S. presidential election, which president-elect Joe Biden won, was halted after protesters entered the building.

U.S. lawmakers are hiding in the building as protesters enter both chambers of Congress.

Trump has sent the National Guard to aid police, but has not demanded that his supporters stand down or leave federal property.
