The United States has experienced two presidential impeachment trials, and is in the process of a third. Although each impeachment trial may have unique procedural aspects, they all follow the same set of steps:
- A member of the House of Representatives introduces an impeachment resolution.
- The House Judiciary Committee reviews the accusations, and if a majority of the committee agrees, writes the Articles of Impeachment.
- The House of Representatives debates the Articles, then holds a vote; if a majority of the entire House agrees, the charges are then brought to the Senate.
- The Senate then holds a trial, in which the entire Senate functions as the jury, and the Chief Justice of the Supreme Court is the presiding judge.
- After the Senate has deliberated, they hold a vote; a two-thirds majority of the Senate is required to convict the President and remove them from office.
