President Donald Trump has urged supporters to "stay peaceful" after Congress was forced to go into lockdown amid clashes between protesters and police at the Capitol Building.
"I am asking for everyone at the U.S. Capitol to remain peaceful. No violence! Remember, WE are the Party of Law & Order – respect the Law and our great men and women in Blue. Thank you!" Trump wrote in a tweet on Wednesday.
In an earlier Tweet, he said: "Please support our Capitol Police and Law Enforcement. They are truly on the side of our Country. Stay peaceful!"
Protesters from a pro-Trump rally breached the Capitol Building and clashed with police, prompting the police to put the building under lockdown. Both chambers, whose lawmakers had been debating the certification of Electoral College votes for the presidential election, were put into recess.
Others echoed the president's call for peace. Sen. Tom Cotton (R-Ark.) also urged an end to violence.
Rudy Guiliani, Trump's lawyer, called on the president's supporters to act peacefully.
"To all those patriots challenging the fraudulent election, POTUS wants you to EXPRESS YOUR OPINION PEACEFULLY," Guiliani said on Twitter. "We are the law and order party, You are on the right side of the law and history. Act with respect for all."
Ronna McDaniel, chairwoman of the Republican Party, also took to Twitter to denounce the violence: "There is no place for violence in our politics, regardless of which side you are on."
Police escorted out House of Representatives members from the chamber where they had been debating, as lawmakers aligned with Trump challenged the election results. The Senate abruptly adjourned and Vice President Mike Pence, who had presided over a joint session of Congress, was escorted from the chamber.
Officers ordered people in the chamber to drop to the floor for their safety.
Earlier in the day, thousands of Trump supporters attended a rally near the White House to protest alleged election fraud and call for greater transparency in the election process. Trump addressed the crowd, saying he would "never concede."
"You don’t concede when there’s theft involved,” Trump said. “We will not take it anymore … we will stop the steal.”
