The power to impeach a president in the United States typically lies with the House of Representatives. Impeachment is a constitutional process intended to remove a president from office for committing "high crimes and misdemeanors." A simple majority vote in the House is required to initiate impeachment proceedings. Once the House votes to impeach, the process moves to the Senate, which conducts a trial to determine whether to convict and remove the president. This two-step process ensures that both chambers of Congress are involved in holding the president accountable for serious misconduct.
