Capitol riots: Congress certifies Joe Biden's victory after chaotic scenes

The US Congress has certified Joe Biden's victory in the presidential election, hours after supporters of Donald Trump stormed the building in an attack that saw four people die.

Lawmakers resumed the session after police removed a mob that had been encouraged by President Trump as part of his attempt to overturn his defeat.

The certification clears the way for Mr Biden to be sworn in on 20 January.

In response, Mr Trump finally pledged an "orderly transition" of power.

Wednesday's chaotic scenes followed months of escalating rhetoric from Mr Trump and some Republican allies that sought to undermine the result of the 3 November election. The invasion of the Capitol by the president's supporters - some armed - was an event without precedent in modern American history.

Washington DC Mayor Muriel Bowser said one of the four who died - a woman named as Ashli Babbitt - was part of a group that forced entry into the chamber of the House of Representatives while it was still in session. They were confronted by plainclothes officers, and an officer pulled out a weapon and fired it.

The US Capitol Police said the employee involved had been put on administrative leave pending an investigation.

Local media said Ashli Babbitt was a San Diego-area US Air Force veteran and Trump supporter. She was proclaimed dead at hospital.

One woman and two men died as a result of "medical emergencies", officials said, without giving details. At least 14 members of the police were injured.

The FBI is now seeking to identify those involved in the rampage, which came after Mr Trump had told a rally he would never concede the election and urged his supporters to march on the Capitol.

It also came on the day two Democrats won Senate seats in elections in Georgia, giving the party effective control of the whole of Congress. This major political victory will ease the passage of Mr Biden's agenda after he is inaugurated.

What happened in Congress?

Democrat Joe Biden's victory was confirmed at about 03:30 local time (08:30 GMT) on Thursday in a joint session presided over by Republican Vice-President Mike Pence, who called the violence a "dark day in the history of the United States Capitol".

Mr Biden blasted the "insurrection" as Mr Trump, while telling the mob to "go home", continued to make false claims of electoral fraud. The outgoing president's Twitter and Facebook accounts were later frozen and remain blocked.

Objections by some Republican lawmakers to overturn the result in Arizona and Pennsylvania were rejected. Congress formally certified the final electoral college vote, with Mr Biden receiving 306 votes to Mr Trump's 232.

For days Mr Trump had been piling pressure on his vice-president to block certification. But in a letter to Congress on Wednesday, Mr Pence said he had no "unilateral authority to decide which electoral votes should be counted".

In declaring the final vote totals, Mr Pence said this "shall be deemed a sufficient declaration of the persons elected president and vice-president of the United States".

Shortly afterwards Mr Trump said in a statement: "Even though I totally disagree with the outcome of the election, and the facts bear me out, nevertheless there will be an orderly transition on January 20th."

On Thursday the White House press office issued a statement saying it "grieves the loss of life" and will continue "to pray for a speedy recovery for those who suffered injury".

A deadly day and Trump's legacy

This is how the Trump presidency ends. Not with a whimper, but with a bang.

For weeks, Donald Trump had been pointing to 6 January as a day of reckoning. It was when he told his supporters to come to Washington DC, and challenge Congress - and Vice-President Mike Pence - to discard the results of November's election and keep the presidency in his hands.

Crisis can bring political opportunity, and there are many politicians who will not hesitate to use it to gain advantage.

Donald Trump - for now - is still in power. And while he may be chastened, he may be sitting in the White House residence watching television temporarily without his social media outlet, he will not be silent for long.

And once he decamps for his new Florida home, he could begin making plans to settle scores and, perhaps, someday return to power and rebuild a legacy that, for the moment, lies in tatters.Biden win certified by Congress after chaotic day

What's been the reaction from lawmakers?

In addition to Mr Pence, some Republicans who previously stood by the president have now spoken out.

• Has the Capitol been attacked before?

• The people who still believe Trump won

• What is the electoral college?

Senate Republican leader Mitch McConnell definitively broke with Mr Trump in an emotional speech from the chamber floor on Wednesday, saying: "If this election were overturned by mere allegations from the losing side, our democracy would enter a death spiral."

After the session resumed, Senate Democratic leader Chuck Schumer blasted the mob at the Capitol as "rioters and insurrectionists, goons and thugs, domestic terrorists", saying the president "bears a great deal of the blame".

Senator Kelly Loeffler, who lost her bid for election in Georgia's vote on Tuesday, said she could no longer in good conscience vote against certification as she had originally planned, citing the "abhorrent" invasion of the Capitol.

With two weeks before Mr Trump leaves office, there are calls for him to be removed beforehand for instigating the attack on Congress. US media say some members of his cabinet have discussed invoking the 25th amendment to the Constitution, which deals with removing a president deemed unfit for office.

Democrats on the House Judiciary Committee have said that Mr Trump's actions meet the amendment's requirements.

How did the attack unfold?

On Wednesday afternoon protesters surged up the Capitol steps shoving past barricades and officers in riot gear to penetrate the building. The mob - some of whom wore body armour - used chemical irritants to attack police, according to Washington police.

They shouted and waved pro-Trump, US and Confederate flags as they roamed the halls, demanding the results of the presidential election be overturned.

Members of Congress scrambled for cover under their seats as tear gas was fired. Several thousand National Guard troops, FBI agents and US Secret Service personnel were deployed to help overwhelmed Capitol police.

The apparent ease with which Trump supporters were able to act has raised serious questions about security. Two pipe bombs were recovered, one from the Democratic National Committee offices, not far from the Capitol, and one from the nearby Republican National Committee headquarters.

The occupation of the Capitol lasted more than three hours before the building was secured by law enforcement. At least 52 people have been arrested, the vast majority of them for violating the 18:00 to 06:00 curfew.

Washington is under an extended state of emergency until after Mr Biden's inauguration.

After sitting at the desk of US House Speaker Nancy Pelosi, one protester left a message reading "we will not back down"

Responding to the violence, Mr Biden said the mob's activity "border[ed] on sedition" and that democracy was "under unprecedented assault".

"To storm the Capitol, to smash windows, to occupy offices on the floor of the United States Senate, rummaging through desks, on the House of Representatives, threatening the safety of duly elected officials. It's not protest; it's insurrection."

Mr Trump posted a recorded video on Twitter saying: "I know your pain. I know you're hurt... We had an election that was stolen from us. It was a landslide election, and everyone knows it, especially the other side. But you have to go home now. We have to have peace."

For the first time, Twitter froze Mr Trump's account, saying it would be locked for 12 hours. The social media giant demanded he delete three tweets that it said could stoke violence and threatening "permanent suspension". Facebook and Instagram followed suit.

Hours earlier, Mr Trump had addressed a "Save America Rally" outside the White House, where he encouraged supporters to keep contesting the election result: "Our country has had enough and we will not take it anymore."

Political figures from around the world condemned the violence. In the US, former President Barack Obama said history would rightly remember the assault on the Capitol as "as a moment of great dishonour and shame for our nation".

Former President George W Bush said: "It is a sickening & heartbreaking sight. This is how election results are disputed in a banana republic - not our democratic republic."
