The January 6th committee’s final report asserts that former US president Donald Trump criminally engaged in a “multi-part conspiracy” to overturn the lawful results of the 2020 presidential election and failed to act to stop his supporters from attacking the Capitol.
It concludes an 18-month investigation into the former president and the violent insurrection two years ago.
The 814-page report released on Thursday comes after the panel interviewed more than 1,000 witnesses, held 10 hearings and obtained millions of pages of documents.
The witnesses — ranging from many of Mr Trump’s closest aides to law enforcement to some of the rioters themselves — detailed Mr Trump’s actions in the weeks ahead of the insurrection.
The insurrection gravely threatened democracy and “put the lives of American lawmakers at risk”, the nine-member panel concluded.
In a foreword to the report, outgoing Speaker Nancy Pelosi says the findings should be a “clarion call to all Americans: to vigilantly guard our Democracy and to give our vote only to those dutiful in their defence of our Constitution”.
The report’s eight chapters of findings tell the story largely as the panel’s hearings did this summer — describing the many facets of the remarkable plan that Mr Trump and his advisers devised to try and void US president Joe Biden’s victory.
The politicians describe his pressure on states, federal officials, politicians and former vice president Mike Pence to game the system or break the law.
In the two months between the election and the insurrection, the report says: “President Trump or his inner circle engaged in at least 200 apparent acts of public or private outreach, pressure, or condemnation, targeting either State legislators or State or local election administrators, to overturn State election results.”
Mr Trump’s repeated, false claims of widespread voter fraud resonated with his supporters, the committee said, and were amplified on social media, building on the distrust of government he had fostered for his four years in office.
And he did little to stop them when they resorted to violence and stormed the US Capitol.
The massive, damning report comes as Mr Trump is running again for the presidency and also facing multiple federal investigations, including probes of his role in the insurrection and the presence of classified documents at his Florida estate.
This week is particularly fraught for him, as a House committee is expected to release his tax returns after he has fought for years to keep them private.
And Mr Trump has been blamed by Republicans for a worse-than-expected showing in the midterm elections, leaving him in his most politically vulnerable state since he won the 2016 election.
Posting on his social media site, Mr Trump called the report “highly partisan” and falsely claimed it did not include his statement on January 6 that his supporters should protest “peacefully and patriotically”.
The committee noted he followed that comment with election falsehoods and charged language exhorting the crowd to “fight like hell”.
The report details a multitude of failings by law enforcement and intelligence agencies. But it makes an emphatic point that security failures are not what led to the insurrection.
The investigation’s release is a final act for House Democrats who are ceding power to Republicans in less than two weeks, and have spent much of their four years in power investigating Mr Trump.
Democrats impeached Mr Trump twice, the second time a week after the insurrection. He was acquitted by the Senate both times. Other Democratic-led probes investigated his finances, his businesses, his foreign ties and his family.
