Can Donald Trump run for a third term? A look at the US President who served more than two terms

As it stands, Donald Trump cannot run for a third term as president due to the 22nd Amendment of the U.S. Constitution, which strictly limits individuals to two terms in office. However, in a recent interview with NBC News, Trump did not rule out the idea, stating there might be ways around the restriction and emphasizing that he was "not joking."
"I'm not joking... a lot of people want me to do it," he said. "But, I basically tell them we have a long way to go, you know, it's very early in the administration."
Trump has previously floated the idea, telling supporters in January that serving three or even four terms would be "the greatest honor of my life." While he later dismissed this as a joke aimed at the media, some of his allies have continued discussing possible workarounds.

Amending the Constitution to allow a third term would be an extremely difficult process. It would require approval from two-thirds of both the Senate and the House, as well as ratification by three-quarters of state legislatures—an unlikely scenario given the current political landscape. Some Trump supporters have also speculated about a loophole in the 22nd Amendment.
The amendment explicitly prevents someone from being elected to more than two terms but does not directly address succession. Theoretically, Trump could run as vice president in 2028, with a running mate who resigns after taking office, allowing Trump to assume the presidency. While this has never been tested in court, it remains a topic of debate among his allies.
The only President to serve more than two Terms: Franklin D. Roosevelt

Before the 22nd Amendment was passed, there was no legal restriction preventing a president from serving more than two terms—only a long-standing tradition set by George Washington and followed by most early presidents. However, Franklin D. Roosevelt broke this norm by winning a third term in 1940 and a fourth in 1944 during World War II.
Roosevelt’s extended presidency led to concerns about the concentration of power, prompting Congress to pass the 22nd Amendment in 1947. It was ratified in 1951 officially limiting presidents to two elected terms. Since then, no president has been able to serve more than eight years in office.

Roosevelt was an only child from a wealthy family, raised on an estate in New York’s Hudson Valley. He was homeschooled until 14, then attended Groton, Harvard, and later Columbia Law School (though he didn’t complete his degree).
He was a distant fifth cousin of President Theodore Roosevelt and even closer to him by marriage—his wife, Eleanor, was Theodore’s niece. Theodore Roosevelt walked Eleanor down the aisle at their wedding in 1905.

Despite most of his family being Republicans, Roosevelt became a Democrat. He served as assistant secretary of the Navy during WWI and ran as the Democratic vice-presidential candidate in 1920 (but lost).
In 1921, Roosevelt was diagnosed with polio (though modern research suggests it may have been Guillain-Barré Syndrome). Despite his paralysis, he returned to politics, becoming governor of New York in 1928 and later winning the presidency.
His own struggle with paralysis led him to champion polio research, founding the National Foundation for Infantile Paralysis (March of Dimes). This eventually helped fund the development of the polio vaccine in the 1950s.
