Before President Trump took office in 2017, only two presidents had ever been impeached: Andrew Johnson in 1868, and Bill Clinton in 1998. On December 18, 2019, Trump became the third to be impeached when the House voted to send charges of abuse of power and obstruction of Congress to the Senate for a trial.
Although the Senate chose to acquit President Trump, leaving him in office, he now faces an unprecedented second impeachment trial after the House voted to impeach him for inciting an insurrection following the January 6 riot at the Capitol in Washington, D.C.
