The House holds 'the sole Power of Impeachment': the authority to formally accuse the President, Vice President, judges, and other civil officers of treason, bribery, or other high crimes and misdemeanors. Impeachment is the accusation, not the removal.
Read the clause itself, verbatim and in plain language, in the in-app Constitution.
The House of Representatives, exclusively
An inquiry (usually in the Judiciary Committee) produces articles of impeachment; a simple House majority adopts them; House managers then prosecute the case at the Senate trial. What counts as a 'high crime or misdemeanor' is ultimately what the House and Senate say it is, a political judgment the courts have refused to review (Nixon v. United States, 1993).
Terms to know: impeachmentThe House's formal accusation against a President, judge, or other civil officer, by majority vote. Removal requires a separate Senate trial and a two-thirds conviction.Full definition in the glossary
