The Vice Vise President!!??
According to the U.S. order of succession, if both the president and the vice president are, for whatever reason, unable to serve, then the Speaker of the House of Representatives becomes acting president. If he/she also cannot serve, the next individuals in line are the President pro tempore of the Senate and then the Secretary of State.
Vice President Of USA (Joe Bidden)
In a case where both the president and vice president fail to complete a term as president, the Speaker of the House would take their place. This has not yet happened in the history of the United States.
One of the few constitutional duties of the Vice-President is to serve as President of the US Senate.
The vice-president becomes President if the president can not function.
