As the Jan. 6 committee outlined during its prime-time hearing, Donald J. Trump executed a seven-part conspiracy to overturn a free and fair democratic election.

In the entire 246-year history of the United States, there was surely never a more damning indictment presented against an American president than outlined on Thursday night in a cavernous congressional hearing room where the future of democracy felt on the line.

Other presidents have been accused of wrongdoing, even high crimes and misdemeanors, but the case against Donald J. Trump mounted by the bipartisan House committee investigating the Jan. 6, 2021, attack on the Capitol described not just a rogue president but a would-be autocrat willing to shred the Constitution to hang onto power at all costs.

As the committee portrayed it during its prime-time televised hearing, Mr. Trump executed a seven-part conspiracy to overturn a free and fair democratic election. According to the panel, he lied to the American people, ignored all evidence refuting his false fraud claims, pressured state and federal officials to throw out election results favoring his challenger, encouraged a violent mob to storm the Capitol and even signaled support for the execution of his own vice president.

“Jan. 6 was the culmination of an attempted coup, a brazen attempt, as one rioter put it shortly after Jan. 6, to overthrow the government,” said Representative Bennie Thompson, Democrat of Mississippi and the chairman of the select committee. “The violence was no accident. It represents Trump’s last stand, most desperate chance to halt the transfer of power.”

Most incriminating were the words of Mr. Trump’s own advisers and appointees, played over video on a giant screen above the committee dais and beamed out to a national television audience. There was his own attorney general who told him that his false election claims were “bullshit.” There was his own campaign lawyer who testified that there was no evidence of fraud sufficient to change the outcome. And there was his own daughter, Ivanka Trump, who acknowledged that she accepted the conclusion that the election was not, in fact, stolen as her father kept claiming.
