First, an impeachment resolution must be introduced by a member of the House of Representatives. The speaker then has the U.S. House Committee on the Judiciary (or a special committee) hold a hearing on the resolution to decide whether to put the resolution to a vote by the full chamber. A simple majority of the Judiciary Committee must approve the resolution. If the Judiciary Committee approves the resolution, it moves to a full vote on the House floor. If a simple majority of those present and voting in the House approve an article of impeachment, then the president is impeached. Then it goes to the Senate where a trial is held to decide if the president committed a crime and the chief justice of the Supreme Court presides over the trial. The Senate votes, and takes a two-thirds vote of the Senate to convict. If the president is found guilty, he is removed from office and the vice president is sworn-in as president.
