The committee investigating the US Capitol riots on January 6, 2021, says America's democracy came "dangerously close to catastrophe".
Donald Trump's closest advisers also viewed his last-ditch efforts to pressure vice-president Mike Pence to reject the tally of state electors and overturn the 2020 election as "nuts", "crazy" and even likely to incite riots.
Here are the key moments from the latest hearing.
But first, who is John Eastman?
He's emerging as a main figure in the committee's investigation, so let's get you up to speed on who he is.
John Eastman was the conservative lawyer advising the Trump campaign.
He advocated the theory that Mike Pence could stop the vote certification in Congress because the then-vice-president was to preside over the January 6 joint session of Congress to certify Joe Biden's election.
Mr Eastman had argued that Mr Pence could reject results from certain states if he thought they were illegitimate, giving Republicans in those states an opportunity to declare Mr Trump the victor despite the actual vote count.
Mr Trump latched onto Mr Eastman's highly unusual plan to defy historical precedent of the Electoral Count Act, and started pressuring Mr Pence in public and private.
Mr Eastman was subpoenaed by the committee the Capitol riots, but repeatedly invoked his Fifth Amendment rights during his interview. He has also sued to block the panel from obtaining his communications during that time.
Trump's advisers thought his plan was 'nuts', and warned of street riots
The committee played videotaped testimony from Eric Herschmann, a lawyer advising Mr Trump, expressing incredulity at Mr Eastman's theory that a vice-president could overturn an election.
"Are you out of your effing mind?" Mr Herschmann recalled asking Mr Eastman in the recorded testimony.
"You're going to turn around and tell 78-plus million people in this country that your theory is this is how you're going to invalidate their votes?" he said.
Mr Herschmann said Mr Eastman dismissively said "words to the effect of, 'There's been violence in the history of our country to protect the democracy or protect the Republic.'"
A text message from Fox News's Sean Hannity to Mr Trump's chief of staff Mark Meadows about the plan in the run-up to January 6 read: "I'm very worried about the next 48 hours."
Mr Trump's campaign adviser Jason Miller said those around Mr Trump called it "crazy".
Greg Jacob, an attorney for Mr Pence, said the main proponent of that theory, attorney John Eastman, admitted in front of Mr Trump two days before the attack that his plan to have Mr Pence halt the procedure would violate the law.
Mr Jacob said that even Mr Eastman didn't appear to believe his own wild theories.
"He said, 'Absolutely, Al Gore did not have a basis to do it in 2000. Kamala Harris shouldn't be able to do it in 2024 but I think you should do it today,'" Mr Jacob recounted of one conversation with Mr Eastman.
The committee has said the plan was illegal, and a federal judge has said it is "more likely than not" Mr Trump committed crimes in his attempt to stop the certification.
Retired federal judge Michael Luttig called the plan from Mr Eastman, his former law clerk, "incorrect at every turn", and said he would "have laid my body across the road before I would have let the vice-president overturn the 2020 election."
Rioters got within '40 feet' of Mike Pence
As the rioters broke in, Mr Pence hastily evacuated his post presiding over the Senate.
California Representative Pete Aguilar, a Democrat on the committee, told Mr Jacob that Mr Pence and other politicians were at one point only 40 feet from the rioters.
Mr Jacob, who was with Mr Pence at the time, said they had "heard the din" of the violent mob as they evacuated but he didn't know the rioters were that close.
The committee also showed never-before-seen photos of Mr Pence after he had evacuated to a secure location in the Capitol, including one photo in which he was reading one of Mr Trump's tweets.
In one video played by the committee, a Trump supporter said he had heard reports that Mr Pence had "caved", and if he did they were going to drag "politicians through the streets."
Mr Jacob said Secret Service agents wanted them to evacuate the building but Mr Pence refused to get in the car.
"The vice-president didn't want to take any chance" that the world would see him leaving the Capitol, Mr Jacob said.
That pressure, the committee asserts, put Mr Pence in immediate danger after rioters marched down to the Capitol and chanted for his death.
"Donald Trump turned the mob on him," said Democratic Representative Bennie Thompson, who is also panel chairman.
Pence 'did his duty' by defying Trump
In video testimony, Mr Pence's former chief of staff, Marc Short, said the vice-president told Mr Trump "many times" that Mr Pence did not agree with the scheme.
But Mr Trump kept up the pressure anyway.
Mr Pence did not give in. He declared Mr Biden the next president early the next morning, after the congressional session resumed and the rioters were cleared.
Politicians on the nine-member panel, and the witnesses who testified at the hearing, all described Mr Pence's decision as having averted a constitutional crisis.
Panel chairman Bennie Thompson opened the latest hearing by repeating Mr Pence's own words that there was "almost no idea more un-American" than the one the vice-president was being asked to perform: reject the vote.
By refusing Mr Trump's demands, Mr Pence "did his duty", the panel's vice-chair, Republican Representative Liz Cheney, said.
The wife of a Supreme Court Justice could be invited to speak
Mr Thompson, the head of the congressional committee, said he believed Virginia "Ginni" Thomas, wife of Supreme Court Justice Clarence Thomas, should be invited to speak to the panel.
The Washington Post reported on Wednesday that the committee had obtained emails between Ms Thomas and Mr Eastman.
The emails showed that Ms Thomas's efforts to overturn the election were more extensive than previously known, the Post said.
"It's time for us to invite her [Ms Thomas] to come talk," the committee chairman said.
Virginia Thomas is active in conservative political circles and said she attended a rally Mr Trump held before the Capitol riot.
At the rally, Mr Trump made a fiery speech repeating his unfounded allegations that his election defeat was due to widespread fraud and urged his supporters to march on Congress.
Ms Thomas's political involvement has raised questions about whether her husband should recuse himself from cases involving Mr Trump and the Capitol riot.
In January, her husband was the lone dissenting voice when the Supreme Court rejected Mr Trump's request to block the release of White House records sought by the January 6 committee.
Ms Thomas told the Daily Caller she "can't wait to clear up misconceptions".
Trump demands networks give him 'equal' coverage
Hours before the latest hearing, Mr Trump took to his own social media platform, Truth Social, to demand all major networks provide him with "equal time" so he can reiterate his debunked claims about election fraud.
"It is a one sided, highly partisan Witch Hunt, the likes of which has never been seen in Congress before," he wrote.
"Therefore, I am hereby demanding EQUAL TIME to spell out the massive Voter Fraud & Dem Security Breach!"
"Equal time means sitting your lying ass in a witness chair," Congressman Eric Swalwell said in response on Twitter.
