Only two presidents have faced an impeachment trial, both of them Democrats and both of them acquitted. The first was Andrew Johnson, who in 1868 was acquitted by one vote of violating the previous year’s Tenure of Office Act. The second was Bill Clinton, who in 1998 was acquitted by a much larger margin of perjury and obstructing justice in relation to the Monica Lewinsky scandal. But only one president, Republican Richard Nixon, has ever resigned, and that was to avoid inevitable impeachment for corruption in relation to the Watergate scandal. Nixon was granted an unconditional pardon by his successor Gerald Ford.

Legal Definition of impeach
1 : to charge with a crime or misconduct; specifically : to charge (a public official) before a competent tribunal (as the U.S. Senate) with misconduct in office Editor's note: Impeachment is the first step in removing an officer from office. The president, vice president, and other federal officers (as judges) may be impeached by the House of Representatives. (Members of Congress themselves are not removed by being impeached and tried, but rather are expelled by a two-thirds majority vote in the member's house.) The House draws up articles of impeachment that itemize the charges and their factual bases. The articles of impeachment, once approved by a simple majority of the House members, are then submitted to the Senate, thereby impeaching the officer. The Senate then holds a trial, at the conclusion of which each member votes for or against conviction on each article of impeachment. Two-thirds of the Senate members present must vote in favor of conviction. Once convicted, the officer can be removed from office. Although the Constitution specifies that an officer is to be impeached for high crimes and misdemeanors, impeachment can also occur for misconduct that is not necessarily criminal (as violation of the Constitution). Because impeachment is the first step taken to remove an officer from office, impeach is often used in general contexts to refer to the removal itself, but that is not its specific legal meaning. An officer generally cannot be impeached for acts done prior to taking office.
2 : to cast doubt on: as a : to attack the validity of (a judgment or verdict) because of judicial or juror misconduct b : to challenge the credibility of (a witness) or the validity of (a witness's testimony) a witness, including a criminal defendant who testifies in his own behalf, may be impeached on the ground of former conviction — W. R. LaFave and A. W. Scott, Jr. — see also impeachment evidence at evidence — compare rehabilitate
