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.
