WASHINGTON, Jan 7 ― The chaos in the US Capitol today unfolded after President Donald Trump spent weeks whipping up his supporters with false allegations of fraud in the November 3 election, culminating in a call to march to the building that represents US democracy.

Trump, who has refused to concede his loss to Democratic President-elect Joe Biden, had urged his supporters multiple times to come to Washington for a rally yesterday, the day the US House of Representatives and Senate were scheduled to certify the results of the Electoral College.

"Statistically impossible to have lost the 2020 Election,” Trump, a Republican, tweeted on December 20. "Big protest in DC on January 6th. Be there, will be wild!”

They turned out in the thousands and heard the president urge them to march on the Capitol building to express their anger at the voting process and to pressure their elected officials to reject the results.

"We're going to walk down to the Capitol and we're going to cheer on our brave senators and Congressmen and women,” Trump told the crowd, speaking with the White House as a backdrop.

Appearing at what could be his last rally as the sitting president, Trump exhorted his supporters "to fight.”

"We will never give up, we will never concede,” Trump said, delighting the crowd by calling Democratic victories the product of what he called "explosions of bulls***.”

"Bulls***! Bulls***! Bulls***!” people chanted in reply.

Trump has sought for weeks to thwart a peaceful transfer of power, aided by groups like "Stop the Steal,” which promoted the day's protest and peddled false claims about voter fraud on Facebook and other social media.

Today's events were the culmination of those efforts. About 50 minutes into the speech, some of his supporters, waving Trump flags, began heading toward Capitol Hill, where unprecedented mayhem ensued.

Protesters fought through police barricades, stormed the building and entered lawmakers' chambers. The certification process was stopped and Vice President Mike Pence and members of Congress were evacuated.

One civilian was shot dead, Washington police said. As night fell, a Capitol official said the building had been cleared, but outside some way from the grounds, scores of protesters remained, including members of militia and far-right groups.

‘I know you’re hurt’

Monitoring the scenes of violence on cable news television from the Oval Office, Trump tweeted about an hour after the Capitol was put on lockdown that the protesters should "remain peaceful.”

As criticism mounted that he had incited a riot, he was urged to say more by a Trump stalwart, House Republican leader Kevin McCarthy, and some of the advisers who remain in the White House for his dwindling days in office.

Biden had come out forcefully on live television and said the violence was "not a protest, it's insurrection.” He called on Trump to demand "an end to this siege.”

Eventually, Trump posted a recorded video on Twitter.

"I know you're hurt. We had an election that was stolen from us. It was a landslide election,” Trump said, repeating familiar falsehoods. "But you have to go home now. We have to have peace. We have to have law and order.”

He posted another message that called the mob "great patriots” who were reacting to an election victory "viciously stripped away.” Twitter later hid three tweets and locked Trump's account.

Trump's failure to rein in his supporters stood in sharp contrast to his attitude last summer when he threatened arrests and the use of force to break up protests against racial inequality.

During the Black Lives Matter protests, Trump discussed using the military in response, and an area near the White House was forcibly cleared for him to stage a photo-op in front of a church, holding a Bible.

Democrats and some Republicans blamed Trump for inciting the violence today.

"Today’s violent assault on our Capitol, an effort to subjugate American democracy by mob rule, was fomented by Mr. Trump,” Jim Mattis, a former defense secretary under Trump, said in a statement.

Weeks have passed since the states completed certifying that Biden won by 306 votes in the Electoral College to Trump's 232, and Trump's extraordinary challenges to the result have failed in courts across the country.

Yet Trump's rally speech today was filled with grievances and voter fraud allegations that have not been backed up with evidence.

He singled out several Republican lawmakers for criticism, including Senator Mitt Romney and Representative Liz Cheney, while hailing as heroes those who have sided with him to stop the electoral votes from being certified.

Several times he also urged Pence to intervene. But while Trump was still speaking, Pence released a lengthy statement saying he would carry out his constitutional duty to certify the vote.

"It is my considered judgment that my oath to support and defend the Constitution constrains me from claiming unilateral authority to determine which electoral votes should be counted and which should not,” Pence wrote.

About an hour later he was being escorted from the House chamber as a mob tried to break in. ― Reuters
