What president has lost their job by impeachment?

No president has ever lost his job due to impeachment. The two Presidents in our history that were impeached were Andrew Johnson in 1868 and Bill Clinton in 1998. In both cases these Presidents were acquitted and continued to hold office. However, it should be noted that articles of impeachment were being considered against Richard M. Nixon in 1974. President Nixon would most likely have been impeached had he not resigned from office.
