Senators sworn in for Trump's 2nd impeachment trial

Trump is the only president to have been impeached by the House of Representatives twice and the first to face a trial after leaving power, with the possibility of being disqualified from future public office if convicted by two-thirds of the Senate.

The House approved a single article of impeachment - the equivalent of an indictment in a criminal trial - on Jan. 13, accusing him of inciting an insurrection with an incendiary speech to supporters before they stormed the Capitol on Jan. 6. A police officer and four others died in the melee.
