The House of Representatives immediately chooses the president from the top three electoral-vote recipients, with each state delegation receiving one vote.
Section 3
The Senate chooses the vice president
The Senate separately chooses the vice president from the top two vice-presidential electoral-vote recipients, with each senator casting one vote.
Section 4
The vice president-elect or acting successor may serve temporarily
