Final answer:
Impeachment proceedings must be initiated by the House of Representatives. The trial then takes place in the Senate.
Step-by-step explanation:
The effort to initiate impeachment proceedings must be done by the House of Representatives. Impeachment is the process of accusing a government official, such as the President, of serious wrongdoing. If the House of Representatives votes to impeach, the trial takes place in the Senate with the Chief Justice of the Supreme Court presiding.
