DONALD TRUMP was criminally engaged in a “multi-part conspiracy” to overturn the results of the 2020 United States presidential election, according to a damning official report.

The US House of Representatives January 6 committee’s final report, published on Thursday, also said that the former president failed to act to stop his supporters from attacking the US Capitol in Washington DC. 

The 814-page report concludes an extraordinary 18-month investigation into the role of Mr Trump in the violent attempted coup two years ago.

The panel of Democrats and Republicans interviewed more than 1,000 witnesses, held 10 hearings and obtained millions of pages of documents. 

The witnesses, who included some of the former president’s closest aides and some of the rioters themselves, detailed Mr Trump’s actions in the weeks ahead of the insurrection and how his wide-ranging pressure campaign to overturn his defeat directly influenced those who invaded the Capitol on January 6 2021.

The central cause was “one man,” the report says: Mr Trump.

The insurrection gravely threatened democracy and “put the lives of US lawmakers at risk,” the nine-member panel concluded.

The report’s eight chapters describe the remarkable plan that Mr Trump and his advisers devised to try and void President Joe Biden’s landslide election victory. 

The lawmakers describe his pressure on states, federal officials, lawmakers 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.”

The former president’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 during his four years in office. 

The report says that he did little to stop them when they resorted to violence and stormed the Capitol.

The damning report comes amid plans by Mr Trump to once again run for the presidency in 2024.

The former president, who also faces multiple investigations relating to his business affairs and allegations of sexual misconduct, called the report “highly partisan.”

Earlier in the week Mr Trump slammed the members of the committee as “thugs and scoundrels” as he has continued to dispute his 2020 loss.
