Section 3
Statutory succession applies after the vice president
If both the presidency and vice presidency are vacant, federal law places the Speaker of the House, the president pro tempore of the Senate, and then Cabinet officers in the line of succession.

A new vice president can be confirmed
If the vice presidency becomes vacant, the president nominates a replacement who must be confirmed by a majority of both houses of Congress.
