Legally, no.

The two-term limit was set after Franklin Roosevelt was elected to four terms as president. He died in 1945, shortly after his fourth term.

The 22nd Amendment states: “No person shall be elected to the office of President more than twice, and no person who has held the office of President, or acted as President, for more than two years of any term for which a another person elected president must be elected to the office of president more than once.

Constitutional amendments can be repealed, but it is a difficult process. Any proposed amendment to the Constitution must pass the United States House of Representatives and Senate by a two-thirds majority. It will then have to be ratified by three-quarters of the 50 states.
