What deals with the presidential succession?

Presidential succession in the United States is primarily governed by the Presidential Succession Act of 1947, which outlines the order of officials who would assume the presidency in the event of a vacancy. The order begins with the Vice President, followed by the Speaker of the House, the President pro tempore of the Senate, and then the Cabinet members in the order their departments were created. Additionally, the 25th Amendment to the Constitution addresses presidential disability and the procedures for filling a vacancy in the vice presidency. Together, these laws ensure a clear line of authority and continuity in leadership.
