The 6 January riot at the US Capitol caused an estimated $1.5m (£1.1m) in damages, according to a May estimate from the Architect of the Capitol, the federal agency responsible for the maintenance and operation of the complex.

Prosecutors have sought restitution payments from some of the over 700 people arrested in the weeks and months following the riot.

The total cost of the riot, however, is likely to ultimately be far higher. A security funding bill passed in May by the House of Representatives in April included $40m for the Architect of the Capitol for attack-related costs, in addition to $529.7m for security improvements.

In late February, Architect of the Capitol J Brett Blanton told lawmakers that immediate repairs and security improvements had already totaled over $30m.

Blanton said that the damages included broken glass, damaged sound and photography equipment, destroyed historic lanterns and statues, murals and furniture that were damaged by chemical irritants and fire extinguishers.

Earlier this week, Blanton told reporters that a number of other physical repairs had already been conducted over the last year, including reinforced doors, replaced damaged windows and improvements to security lighting and electrical systems.

The Architect of the Capitol also plans to revamp the Capitol’s entire camera system.

The BBC has reached out to Blanton for comment.

'Treason. Traitors. Thugs'.

These were the words members of Congress used for what happened on 6 January in the days after the attack. As members reflect today, a year on, here's a look back at how they described the events in the immediate aftermath.

The US Capitol building is eerily quiet, one year after the rioters stormed the building.

The echo of footsteps on the marble Capitol floors is heard only rarely. There are no more tours of what’s supposed to be the people’s house for the general public - now visits are by appointment only.

The heart of American democracy is home on this anniversary of the Capitol riot to camera crews and a few lawmakers from the 6 January committee investigating the attacks, doing the round of TV live positions.

It’s a subdued atmosphere, though the partisan divisions of a year ago have only widened. Democrats are holding official events here today to remember and reflect on what happened - and top Republicans aren’t joining in, accusing their political rivals of exploiting the anniversary.

Amy Klobuchar - a leading Senate Democrat and 2020 presidential candidate - has just spoken on the Senate floor recalling the trauma of the attack.

Her voice shook with emotion as she described being in the Capitol with the ballots containing the votes cast by the Electoral College - the body that officially casts votes for the presidency - when rioters came to overturn their results. Quick-thinking aides grabbed the box that contained the votes, she said.

She recalls her own staff telling of hiding "to protect themselves right next to the doors where the insurrectionists had invaded”, she said.

The Minnesota senator called on all Americans, regardless of party, to "hold our democracy dear". The nation is "a republic if we can keep it", she said, referring to words by Benjamin Franklin spoken at its founding.

She warned, however that "what was not accomplished with bear spray and bayonets has now been passed on to others to pass bills" - notably to restrict voting rights in various US states.

After Donald Trump supporters rioted in America’s capital last year, companies across the country vowed to cut off donations to politicians seen as fueling the movement.

A year later, much of the corporate world has stood by those commitments.

Corporate donations to politicians who refused to certify Joe Biden’s election victory dropped by, external nearly two-thirds in 2021, according to Popular Information, a newsletter that tracked the responses.

But 2021 was expected to be a slow year for fundraising.

It’s not clear to what extent the tightened purse strings will continue this year, when many in Congress will face re-election.

A group of activists and socially responsible investment groups, including the SEIU labour union, say they will keep the pressure on.

They are seeking investor support for proposals that would require some of America’s biggest companies, including Apple, Wells Fargo and Home Depot, to be more transparent about their political spending and to conduct audits focused on“equity and racial justice”.

“The Jan 6 attack... made political disclosure and accountability even more important,” says Nadira Narine of the Interfaith Center on Corporate Responsibility, which is involved in the campaigns, external.

“As investors we want to know ... how do companies deploy their resources and are they deployed in an effective way?” says Dieter Waizenegger, executive director of the SOC Investment Group.

“Do their values really line up with their actions?”

As the months have passed since 6 January, the perception of the day has becoming increasingly polarised along partisan lines.

Polls like this, showing Democrats and political independents much more likely to hold Donald Trump responsible for the Capitol attack than Republicans, illustrate the point.

It’s yet another indication of the hold the former president continues to have over his party – and a main reason why current and aspiring Republican officeholders in Washington and across the US echo the unsubstantiated claims that the 2020 election was marred by fraud.

The varied responses from Republican figures to today's anniversary offer a glimpse of divisions in the party.

In contrast to those who criticised Biden's speech, Mitt Romney, a Republican senator and one of the few outspoken Trump opponents in the party, echoed the president's themes.

“Democracy is fragile," Romney said today. "It cannot survive without leaders of integrity and character who care more about the strength of winning the next election".

The country would "ignore the lessons of January 6 at our own peril”.

The best way to “show respect” for voters is telling them the truth, the Utah senator said, lamenting “the malaise gripping our current politics”.

Romney - who was the Republican presidential candidate in 2012 - was one of only seven Republican Senators to vote to convict Trump in his impeachment trial on charges that he incited the rioters on 6 January.

Another anti-Trump Republican, former Bush-era Deputy Chief of Staff Karl Rove, condemned party members who “excused the actions” of the rioters in an opinion piece for the Wall Street Journal.

“If Democrats had done what some Trump supporters did on that violent Jan 6, Republicans would have criticised them mercilessly and been right to do so,” he wrote.

Chuck Schumer, the top-ranking Democrat in the Senate, is now speaking on the floor of the chamber as the day's commemorative events roll on.

"The warnings of history are clear - when democracies are in danger, it often starts with a mob," he says.

The New York lawmaker quotes author Charles Dickens in describing the day as "the best of times and the worst of times". He claims the day began with the news Democrats had regained control of the Senate and ended with fear for his life.

The events of January 6 have further drawn the political lines between the two parties and Schumer repeatedly blasts the former president for spreading "poisonous bile" about the 2020 election.

He also slams his Republican counterparts who try to "downplay or excuse or even defend the insurrection".

With a rhetorical flourish, he says: "We didn't look away after the attack on Pearl Harbour. We didn't look away after the attacks of 9/11. We cannot look away after the attack of January 6."

Donald Trump’s close supporters reportedly talked him out of holding a scheduled press conference later today because they believed it would be bad politics and a distraction for Republicans eager to move on from last year’s Capitol riot.

Instead, the former president issued a scathing press statement that won’t get as much attention – but may have confirmed Republican concerns about Trump’s focus, given that it dwelled as much on his unsubstantiated allegations of electoral fraud as it did on attacking Biden’s record as president.

Trump plans to hold a rally in Arizona next week, so this is certainly not his last word in response to Biden’s newly focused attacks.

Although he may not have received the media attention today that a press conference would have generated, he’ll have plenty of opportunities in the months ahead to exert his influence on the Republican Party and the national political dialogue.

Former US President Barack Obama said today that he believes US democracy “is at greater risk” now than it was a year ago.

Claims of electoral fraud “have been embraced by a sizeable portion of voters and elected officials – many of whom know better", he said.

Some state legislatures across the country have attempted to restrict voting rights, while Republican officials who resisted “have been ostracised, primaried and driven from the party”.

The Democrat, who was Biden's boss in the White House from 2009 to 2017, called on Americans to “nurture and protect” US democracy to safeguard the future.

“That responsibility falls to all of us,” he said. “And on this anniversary, nothing is more important.”

South Carolina Republican Senator Lindsey Graham has accused President Biden of “brazen politicisation” of the 6 January riot.

Meanwhile, Florida Governor Ron DeSantis, a vocal critic of President Biden, said that the anniversary of the riot is "not something that most Floridians have been concerned about".

DeSantis added that he believes that events marking the day in Washington are a "politicised Charlie Foxtrot", using military slang for a chaotic situation.

From his resort home in Florida, the former president was watching President Biden's speech.

Donald Trump has just released an angry statement accusing Biden of "destroying our nation".

The current president "used my name today to try to further divide America", Trump said.

Slamming the speech as "political theatre" and "a distraction from the fact Biden has completely and totally failed", Trump laid out a series of grievances with his successor's policies.

He also delved into false claims about the 2020 election. "The complicit media just calls it the Big Lie, when in actuality the Big Lie was the election itself", the former president said.

"The Democrats want to own this day of January 6th so they can stoke fears and divide America," he said.

"I say, let them have it because America sees through their lies and polarisations.”

Biden took aim squarely at his predecessor, saying former President Trump "did not just lose the election, but he tried to prevent the peaceful transfer of power".

Watch the moment he made his pointed comments below.

"Jumbo” photos, extra-large, poster-sized images, of the Bidens have replaced those of the Trumps in the West Wing.

Gone, too, are copies of the Washington Times, a conservative-leaning paper, that used to lie on people’s desks. The Washington Post and other publications that are seen as more liberal have replaced them.

If Trump’s supporters had gotten their way, the place would still belong to them.

During the siege, they chanted: “Whose house? Our house!”

Many still believe that.

A majority of Republican voters - 58% - say they believe Biden wasn't legitimately elected, despite a lack of evidence to support their views, according to a USA Today/Suffolk University poll.

Biden campaigned as a man who could unite the country and won the White House.

Today, though, the country is still divided.

President Biden's speech opened what will be a day of commemoration events in Washington marking the one-year anniversary of the Capitol riot.

In a few moments, Speaker Nancy Pelosi is expected to take to the floor of the House of Representatives with a statement of her own.

She will also lead a moment of reflection with congressional staff members.

At midday (1700 GMT), there will also be prayers and a moment of silence on the House floor.

At 1300 local time (1800 GMT), the top two congressional Democrats - Pelosi and Senate Majority Leader Chuck Schumer - will moderate a conversation with leading historians.

Other Democratic members of the House will provide testimonials and join a prayer vigil in the afternoon.

Meanwhile, some Republicans plan to counter-programme the day's events.

Matt Gaetz and Marjorie Taylor Greene - two provocative pro-Trump members of the House - will hold a news conference at 1415 local time (1915 GMT).

And a right-wing organisation called "Look Ahead America" will hold a candlelight vigil to honour Ashli Babbitt, the pro-Trump rioter who died inside the Capitol, as well as those who have been arrested for their roles that day.

President Biden has told reporters that he believes that the US “must recognise the extent of the wound” caused by the 6 January riot and political divisiveness in the US before moving forward.

Speaking briefly to media following his speech, Biden said that the issues are “way beyond” any “contemporary political battle” between him and his predecessor, former president Donald Trump.

“To heal, you have to recognise the extent of the wound. This is serious stuff,” he said. “That’s what great nations do. They face the truth”.

While Biden’s speech at the US Capitol laid the blame for the Capitol riot on Trump and his supporters, he did not name the former president once during his remarks.

A shift in message?published at 14:50 Greenwich Mean Time 6 January 2022

Last January, Joe Biden gave an inaugural address outside the US Capitol that focused on national healing and unity.

Now, standing in the centre of the building nearly a year later - after it has become clear that the nation is as divided as ever - Biden put unifying rhetoric aside and took dead aim at Donald Trump and his supporters.

In some of the sharpest words directed at his predecessor since the 2020 presidential campaign, Biden condemned Trump’s continued efforts to question the legitimacy of that election.

Not only that, he blasted Republicans who continue to stand behind the former president and endorsed national efforts to enact election reform to counter what he said were Trump-backed attempts to undermine voting rights.

This is an election year in America, with control of the US Congress and several key states hanging in the balance.

Biden’s rhetorical shift could represent a strategic shift, as well - a decision that the Democratic base can most effectively be rallied with anger, not hope.

The US president has ended his nearly 30-minute speech at the Capitol.

In some of the most pointed remarks of his presidency so far, Joe Biden pointedly accused his predecessor Donald Trump and his supporters in the Republican Party of holding "a dagger at the throat of American democracy".

He said the country was locked in "a battle for the soul of America" - the slogan of the 2020 election campaign - and committed to doing everything in his power to defend its values in 2022, a midterms election year.

Biden reiterates that Trump and the mob that attacked the Capitol represented views that "could not be further away from the core of American values".

He notes that part of the American democratic experiment is a "responsibility to accept defeat".

"The pains and scars from that day run deep," he says.

"We are in a battle for the soul of America".

The 6 January rioters came to the US Capitol “in rage” and “held a dagger at the throat of America and American democracy”, Biden continues.

“They didn’t come here out of patriotism or principle,” Biden says. “Not in service of America. Rather, in service of one man", referring to Trump.

Biden also praised US lawmakers for finishing their work of confirming the results of the 2020 election and honoured their oath to “defend the constitution, against all enemies foreign and domestic”.

Biden continues by repeating an oft-heard idea that underpinned his original campaign against Trump - the notion that the US is at an “inflection point” in a struggle between democracy and “autocracy”.

Trump represents an America run by an “autocratic strongman”, he says.

“That is not who we are. That is not who we have ever been,” Biden says. “That is not who we should ever, ever be.”
