who decides impeachment

The power to impeach and remove an elected official from office ultimately lies with the legislative branch of government in most democracies. In the United States, for example, the process of impeachment is initiated by the House of Representatives, which votes on whether to impeach the official. If a majority of the House approves impeaching an official, the case is then transferred to the Senate for trial. The Senate, acting as a jury, determines whether to remove the official from office, with a two-thirds majority vote required for conviction.
