22nd Amendment
The constitutional amendment ratified in 1951 that limits any person to being elected president no more than twice.
The 22nd Amendment to the US Constitution was ratified on February 27, 1951. It establishes that no person shall be elected to the office of president more than twice.
The amendment was passed by Congress in 1947 following Franklin D. Roosevelt's election to four terms. Congress sought to codify the two-term tradition that had been informally observed since George Washington.
Under the 22nd Amendment, a person who served more than two years of another president's unexpired term may be elected president only once more. Someone who served two years or less of another's term faces no additional restriction.
For the 2028 election, President Trump - who was elected in 2024 after having previously served from 2017 to 2021 - is constitutionally barred from seeking a third term.
