Impeachment in the United States - Wikipedia, the free encyclopedia

Actual impeachments of only the following seventeen federal officers have taken place:

Two presidents: Andrew Johnson and Bill Clinton, both acquitted.
...
In addition, Richard Nixon decided to resign in the face of the near certainty of both his impeachment, which had already been approved by the House Judiciary Committee, and the apparent likelihood of his conviction by the Senate.

Just remember, Wikipedia isn't always the most accurate.
