Title 3 › CHAPTER 1 — PRESIDENTIAL ELECTIONS AND VACANCIES › § 19
If there is no President or Vice President, the Speaker of the House must resign from being Speaker and from Congress and then serve as Acting President. If that Acting President dies, quits, is removed, becomes unable to serve, or fails to qualify, the same rule applies to whoever is acting. If there is no Speaker or the Speaker can’t serve, the President pro tempore of the Senate must resign that office and the Senate seat and act as President. A person acting as President keeps serving until the current Presidential term ends, except when they are serving because the President-elect and Vice-President-elect did not qualify — then they serve only until one of them qualifies — or when they are serving because of the President’s or Vice President’s inability — then they serve only until that person’s disability ends. If there is no President pro tempore either, the job goes to the highest-ranking eligible Cabinet officer who is able to serve. The law names 15 Cabinet positions in order, starting with the Secretary of State, then the Secretary of the Treasury, Secretary of Defense, Attorney General, and ending with the Secretary of Homeland Security. That person serves until the Presidential term ends, unless someone with an earlier right becomes able to act (but someone higher on the list later becoming able to act because their disability ends or because they qualify does not automatically cut short the current acting President). Cabinet officers must have been confirmed by the Senate before the vacancy and must not be under impeachment when they would take over. When an officer starts acting as President, taking the oath is treated as leaving their old office, and while they act as President they receive the President’s pay.
