The US House of Representatives committee investigating the 6 January 2021 attack on the US Capitol has issued a subpoena to compel former president Donald Trump to testify before it.
The action could eventually result in Mr Trump's imprisonment if he does not comply.
The house select committee's seven Democratic and two Republican members voted 9-0 in favour of issuing a subpoena for Mr Trump to provide documents and testimony under oath in connection with the attack.
"He is the one person at the centre of the story of what happened on 6 January. So we want to hear from him," said the panel's Democratic chairman, Representative Bennie Thompson.
"He must be accountable. He is required to answer for his actions."
At what was supposed to be its final meeting, the committee members presented information about the actions of Mr Trump before, during and after the assault on the Capitol.
Mr Thompson said the evidence required Mr Trump to testify to give his version of events to the American people.
Republican Representative and deputy chair Liz Cheney noted that 30 people who had testified before the committee had invoked the Fifth Amendment to refuse to answer questions, particularly relating to the former president.
She hinted that a number of them could be referred to the US Department of Justice for possible criminal prosecution.
She named general Mike Flynn, former chief of staff Mark Meadows, advisor Roger Stone and lawyer John Eastman, hinting they could face prosecution.
The committee also published never-before-seen video of Congressional leaders Nancy Pelosi and Mitch McConnell in hiding, phoning the governors of Maryland and Virginia, asking them for policy and military support to reclaim the Capitol from the protesters who had stormed the building.
The vote came after the committee spent more than two hours making its case via statements from members, documents, and recorded testimony.
It heard that Mr Trump planned to deny his 2020 election defeat in advance, failed to call off the thousands of supporters who stormed the Capitol, and followed through with his false claims the election was stolen even as close advisers told him he had lost.
Federal law says that failure to comply with a congressional subpoena for testimony or documents is a misdemeanour, punishable by one to 12 months' imprisonment.
If the select committee recommends a subpoena that is ignored, the full House must vote on whether to make a referral to the Department of Justice, which has the authority to decide whether to bring charges.
The House select committee has been investigating the attack on the Capitol, which left more than 140 police officers injured and led to several deaths, for more than a year, interviewing more than 1,000 witnesses.
Meanwhile, the US Supreme Court has rejected Mr Trump's bid to let an independent arbiter vet more than 100 classified documents that were seized from his Florida home, as he confronts a criminal investigation into his handling of sensitive government records.
The justices in a brief order denied Mr Trump's emergency request that he made on 4 October, asking them to lift a federal appeals court's decision that prevented the arbiter from reviewing more than 100 documents marked as classified.
The documents were among the roughly 11,000 records seized by FBI agents at his Mar-a-Lago estate in Palm Beach on 8 August.
