Tuesday’s hearings presented in-person testimony from three Republican officeholders – one from Arizona and two from Georgia – who were pressured by Donald Trump and his advisers to reverse the results of the 2020 presidential election.

They directly refuted his allegations of electoral fraud and detailed how, as a result, they and their families faced threats and harassment from the former president’s supporters.

The hearing also presented evidence of Republicans who went along with Trump’s efforts. Republican National Committee Chairwoman Ronna McDaniel said, in recorded testimony, that the party apparatus supported plans to organise “contingent” state electors who would claim that Trump had really won key swing states.

The committee displayed text messages from an aide to Republican Senator Ron Johnson of Wisconsin who reached out to an aide to Mike Pence, saying the senator wanted to present those “alternate” votes to the vice-president prior to the 2020 election certification in Congress on 6 January.

Arizona Senate Majority Leader Rusty Bowers, one of the Republicans who testified on Tuesday, spoke of how Republican US Congressman Andy Biggs urged him to de-certify Joe Biden’s victory in Arizona.

If today’s hearings were designed to be an indictment of Trump’s behaviour in the months after his election defeat, it has also been an implicit condemnation of the Republicans who the committee views as facilitating the president’s plans and a celebration of the Republicans who did not.

Georgia is a sore point for Donald Trump. Not only did the traditionally Republican state flip narrowly for Joe Biden in 2020 but it also elected two Democratic senators in 2021 which gave Joe Biden control of the Senate.

Investigations showed there was no election fraud in Georgia, but Donald Trump refused to accept it. We are hearing just what the pressure felt like for Republican state officials - as well as ordinary election count workers there.

One witness, Wandrea "Shaye" Moss, spoke of the death threats she and her mother faced after Trump wrongly accused her of adding false ballots from a suitcase.

The committee wants to show this pressure was part of an elaborate plan for Trump to overturn the election.

However, it does need to prove criminal intent - which the committee is attempting to do through testimony and documents.

If the Department of Justice chooses to, it could eventually level charges against Trump and his aides.

Chairman Bennie Thompson says the committee's fifth public hearing - on Thursday - will show how Trump was the "driving force" behind efforts to involve the Department of Justice in his actions.

Thompson says Richard Donaghue, a former senior official at the Department of Justice, will testify.

Today's hearing has now come to a close.

Today's session is the fourth of the 6 January committee hearings, which began earlier this month. It focused on Donald Trump's efforts to put pressure on local election officials in a bid to overturn the 2020 presidential election result.

Here's a snapshot of what's been said during previous sessions.

• In its third hearing, the committee said the ex-president tried to pressure former Vice-President Mike Pence into unilaterally overturning the 2020 election result
• Committee chairman Bennie Thompson said "democracy came dangerously close to catastrophe"
• Pence's life was in danger due to his proximity to the rioters, committee member Pete Aguilar said
• In the first two hearings, the committee lay out its case that the riot formed part of a far-reaching conspiracy to keep Trump in the White House
• The committee made the case that the riot directly followed claims from Trump and some of his allies - such as former New York mayor Rudy Giuliani - that the election was stolen
• To make its case, the committee used testimony from members of Trump’s inner circle, including former Attorney General William Barr and daughter Ivanka Trump

Today's hearing is now coming to a close, with lead questioner Adam Schiff delivering his final statement.

Schiff criticises the actions of then-President Donald Trump following the November 2020 election.

"What he did was without a doubt unconstitutional, unpatriotic, and un-American," he says.

As Shaye Moss wraps up her testimony, Congressman Adam Schiff asks Moss to allow her mother "the last word".

A tearful Ruby Freeman testifies via video that: "There is nowhere I feel safe."

"Do you know what it feels like to have the president of the United States target you?" she asks, her voice shaking.

She says presidents ought to protect their citizens, but chose to single out a proud American citizen doing her duty in the midst of a pandemic.

Chairman Bennie Thompson thanks both witnesses, noting the threats they and other election workers have faced from Trump allies "poses a threat to our democratic process".

Shaye Moss says the threats she faced over the 2020 election results have "affected my life in every way".

"I no longer give out my business card," she says.

Moss says she doesn't ever want to go anywhere - including the grocery store - and has gained about 60 pounds in weight.

She adds that Trump supporters visited her grandmother's home, looking for her and hoping to make a "citizen's arrest".

In recorded testimony, her mother Ruby Freeman testifies that the threats prompted her to leave her home for her own safety.

"It was horrible," Freeman says on video, adding she was asked to remain in hiding "at least until the inauguration" of Joe Biden as president.

"I won't even introduce myself by my name anymore," she says.

Shaye Moss, who - along with her mother Ruby Freeman - became the target of unsubstantiated conspiracy theories in her job as an election worker in Fulton County, Georgia is currently speaking.

In recorded messages, former President Trump called her "a professional vote-scammer and hustler", mentioning Moss and Freeman by name on several occasions.

Introduced by Chairman Thompson as an "unsung hero... doing the hard work of keeping our democracy functioning", Moss says she has loved her job for more than 10 years.

Her grandmother taught her the importance of having the right to vote, she says.

"A lot of people before me, older people in my family, did not have that right," she explains.

Moss says she enjoyed helping voters, from college students to the elderly who "like to call, like to talk".

Following allegations of fraud by Trump and his attorney Rudy Giuliani, she faced "a lot of threats wishing death upon me" and messages like "be glad it's 2020, not 1920", she testifies.

"I felt horrible for picking this job and for always wanting to help."

The first three witnesses have now been dismissed.

The committee moves on to the final portion of today's hearing, in which we are hearing about threats made to Georgia election worker Shaye Moss.

Gabriel Sterling, an election official in Georgia, recounts his difficulties reasoning with people who felt in their "hearts" that the 2020 election result was wrong.

Watch his testimony in the video above.

A phone call in which former President Trump repeatedly presses Georgia Secretary of State Brad Raffensperger to "find" the votes he needed to win the state has been central to today's hearing.

Raffensperger goes through a laundry list of allegations made by the Trump team in a lawsuit filed against the state.

He says, despite their lawsuit claiming 10,315 dead people voted, a thorough review found a total of only four.

The secretary also says further investigation debunked claims about illegal votes, made by underage and non-registered voters, as well as felons.

"We had many allegations and we investigated every single one of them," Raffensperger says.

"We ran the rabbit trail to make sure our numbers were accurate."

In his testimony, Georgia election official Gabriel Sterling describes his frustrations with trying to convince people of "the facts" following the 2020 election result in the state - a result which Trump was publicly disputing.

"It was like a shovel trying to empty the ocean," he says.

Arizona Speaker of the House Rusty Bowers testified a short while ago that it "became a pattern" in his life to worry about threats to his safety after he was singled out by former President Trump.

A video from a news conference on 1 December 2020 by Georgia election official Gabriel Sterling - who just started testifying - was shown to the committee.

In the video, Sterling pleads with Trump and Republicans to condemn baseless claims that the election was stolen.

"Mr President, you have not condemned these actions or this language," said Sterling.

"Senators, you have not condemned these actions or this language. We need you to step up and if you're going to take a position of leadership, show some!"

He added: "Death threats, physical threats, intimidation, it's too much, it's not right, they've lost the moral high ground to claim that it is."

Georgia's top election official is up next.

Brad Raffensperger begins his testimony by confirming that Joe Biden won the state in the November 2020 election by nearly 12,000 votes.

He's expected to talk about an alleged attempt by Trump to ask Raffensperger to "find" enough votes that could overturn the result.

Republican politicians are testifying to the committee as it explores the events around the attack on the US Capitol building on 6 January 2021. Thanks for joining our live coverage.

Here's a quick look at what's been said so far today:

• Rusty Bowers, the House speaker in Arizona, has given an emotional defence of his oath of office, saying Donald Trump asked him to violate his promise to the American people by pressurising him to overturn 2020 election results
• Bowers was given a hug by committee vice-chair Liz Cheney after describing protests outside his house from angry Trump supporters, as well as a deluge of emails, calls and texts that left him unable to do his job
• The committee also played a video which featured the testimony of officials in other states won by Joe Biden in the 2020 presidential vote. They similarly recalled attempts at intimidation from Donald Trump and his allies

The committee has returned for part two of today's hearing.

It's shifting its focus from Arizona to what happened in the state of Georgia in the wake of the 2020 presidential election, committee chair Bennie Thompson says.

Lawmakers on the 6 January committee have name-dropped some of their own colleagues during these hearings.

One representative, Adam Biggs, was just brought up in the investigation because he allegedly asked the Arizona Speaker of the House to sign on to a letter decertifying the state's election results on the day of the riot.

Like many Republicans, who say the Democratic-led hearings are partisan propaganda, Biggs does not appear to be watching.

He tweeted a short while ago that he will be hosting a public event today that blames the Biden administration for inflation and energy issues.
