U.S. Constitution, Article II — The Executive Branch, Section 1, Clause 6
[In Case of the Removal of the President from Office, or of his Death, Resignation, or Inability to discharge the Powers and Duties of the said Office, the Same shall devolve on the Vice President, and the Congress may by Law provide for the Case of Removal, Death, Resignation or Inability, both of the President and Vice President, declaring what Officer shall then act as President, and such Officer shall act accordingly, until the Disability be removed, or a President shall be elected.]
Modified by the Twenty-Fifth Amendment.
Notes
Requires the powers and duties of the presidency to devolve on the Vice President if the President is removed, dies, resigns or is unable to discharge them. Allows Congress to provide by law which officer acts as President when both offices are affected, until the disability is removed or a President is elected.
