Though it might be more fun if it meant "canning peaches for the winter," impeachment is actually a formal document accusing a public official with misconduct.
The United States Constitution gives the legislative branch the power of impeachment, that is, to press formal charges of misconduct against a sitting president. The House of Representatives makes the formal charges, and the trial is held in the Senate. A two-thirds majority of the Senate is required for a conviction. Two United States presidents — Andrew Johnson and William Clinton — have been impeached. Neither was convicted. Other federal officials, like judges, can also be impeached.
