Presidential Succession & the 25th Amendment

Who becomes president if the President can't serve, and how far past the Vice President that line actually runs, is settled by a mix of the Constitution, a 1947 federal law, and one amendment written specifically to close the gaps. Here is how the full system works, and every time it has actually been used.

Article II + 25th Amendment (1967)18 Positions in the Line of Succession

One Sentence in Article II, Three Federal Laws to Fill It In

The Constitution gives Congress the power to decide who acts as president if both the President and Vice President can't serve, but it doesn't say who that should be. Congress has answered that question three times since 1792, each time in a different order.

The Full Line of Succession Today

Set by the Presidential Succession Act of 1947, as amended in 2006. If the President can't serve, the office passes down this list until it reaches someone able and eligible to take it.
