Donald Trump has become the third US president in history to be impeached by the House of Representatives, setting up a trial in the Senate that will decide whether he remains in office.
The House voted on two charges – that the president had abused his power and that he had obstructed Congress.
Nearly all Democrats voted for the charges and every Republican against.
President Trump’s Republicans control the Senate so it is highly unlikely he will be removed from power.
Democrats are already unhappy at the way the trial could be held. House Speaker Nancy Pelosi has now indicated it might delay sending the articles of impeachment to the Senate, in order to bargain on the terms of the proceedings.
This could put off the trial for an indefinite period, denying Mr Trump his expected acquittal.
Mr Trump remained defiant as the voting took place, telling a campaign rally in Battle Creek, Michigan: “While we’re creating jobs and fighting for Michigan, the radical left in Congress is consumed with envy and hatred and rage.”
