"History will rightly remember today's violence at the Capitol, incited by a sitting president who has continued to baselessly lie about the outcome of a lawful election," wrote the former president.
"To those who are disappointed in the results of the election: Our country is more important than the politics of the moment," George W. Bush said in his rebuke of President Trump.
For years, those in charge of elections have said stoking false fears about voting would one day lead to violence. On Wednesday, they were proved right.
"We can't allow him to remain in office, it's a matter of preserving our Republic and we need to fulfill our oath," wrote the Minnesota Democrat, as Trump supporters stormed the U.S. Capitol.
As Wednesday's tally of the Electoral College vote highlighted a bitter divide between the parties, the Capitol went into a lockdown because of protests.
After the president addressed the crowd gathered to protest President-elect Joe Biden's win, Trump supporters pushed past barriers onto the Capitol grounds.
With most of Georgia's votes counted in the Jan. 5 runoffs that will decide control of the U.S. Senate, Raphael Warnock and Jon Ossoff are leading the Republican incumbents above the .5% margin for a recount, according to unofficial election results.
The vice president was presiding as the Electoral College vote count is tallied. As violence broke out at the Capitol, President Trump rebuked Pence for following the law.
In raising objections to states' Electoral College certifications, many congressional Republicans are likely to cite a number of debunked conspiracy theories that President Trump has been pushing.
Republicans will see more of 100 of their House members and one dozen Senators object to election's results. Those objections highly unlikely to prevail.
