The Twenty-fifth Amendment (Amendment XXV) to the United States Constitution addresses issues related to presidential succession and disability.
It clarifies that the vice president becomes president if the president dies, resigns, or is removed from office by impeachment. It also establishes the procedure for filling a vacancy in the office of the vice president. The amendment provides for the temporary transfer of the president's powers and duties to the vice president, either on the president's initiative alone or on the initiative of the vice president, together with a majority of the president's cabinet.
