Donald Trump has become the first president in US history to be impeached twice, after being charged with “incitement of insurrection” over last week’s deadly storming of Congress.
The House of Representatives accused Mr Trump of encouraging violence with his false claims of election fraud.
He now faces trial in the upper chamber, the Senate, but not before he leaves office next Wednesday.
Senators can vote to bar him from ever holding public office again.
In a video released after the vote in the House on Wednesday, Mr Trump called on his followers to remain peaceful, without mentioning his impeachment.
“Violence and vandalism have no place in our country… No true supporter of mine would ever endorse political violence,” he said, striking a sombre and conciliatory tone.
The FBI has warned of possible armed protests planned for Washington DC and all 50 US state capitals in the days before Joe Biden, a Democrat, is inaugurated as the new US president.
