Who was the first U.S. President to be impeached?
Andrew Johnson was impeached on February 24, 1868 in the U.S. House of Representatives on eleven articles of impeachment detailing his “high crimes and misdemeanors”, in accordance with Article Two of the United States Constitution. The House vote made President Johnson the first president to be impeached in U.S. history.
The trial ended on May 26 with Johnson’s opponents narrowly failing to achieve the two-thirds majority necessary to convict him. Andrew Johnson and Bill Clinton are the only two presidents that have been impeached in United States history, and neither was convicted of the charges filed against him. Nixon most likely would have been impeached had he not resigned first.
