US President Donald Trump has been impeached by the House of Representatives days before leaving office, becoming the first American president to be impeached twice.

The previous three impeachments, those of presidents Andrew Johnson, Bill Clinton and Mr Trump, took months before a final vote, including investigations in the House and hearings.
