WEST PALM BEACH, Fla. (AP) — On Sunday, President Donald Trump emphasized that he was “not joking” about the possibility of serving a third term, strongly suggesting that he is exploring ways to bypass the constitutional limits that prevent him from continuing his presidency beyond early 2029.

“There are methods which you could do it,” Trump said in a telephone interview with NBC News.

He also said “it is far too early to think about it.”

The 22nd Amendment, incorporated into the Constitution in 1951 following President Franklin D. Roosevelt’s unprecedented four-term election, explicitly states that “no person shall be elected to the office of the President more than twice.”

During an interview with NBC’s Kristen Welker, Trump was questioned about whether one strategy for securing a third term might involve Vice President JD Vance running for president and then “passing the baton” back to Trump thereafter.

“Well, that’s one,” Trump responded. “But there are others too. There are others.”

“Can you tell me another?” Welker asked.

“No,” Trump replied.

Vance’s office did not immediately respond to a request for comment from The Associated Press.

Trump, who would be 82 at the end of his second term, was asked whether he would want to keep serving in “the toughest job in the country” at that point.

“Well, I like working,” the president said.

He suggested that Americans would go along with a third term because of his popularity. He falsely claimed to have “the highest poll numbers of any Republican for the last 100 years.”

Gallup data shows President George W. Bush reaching a 90% approval rating after the attacks on Sept. 11, 2001. His father, President George H.W. Bush, hit 89% following the Gulf War in 1991.

Trump has maxed out at 47% in Gallup data during his second term, despite claiming to be “in the high 70s in many polls, in the real polls.”

Trump has mused before about serving longer than two terms before, generally with jokes to friendly audiences.

“Am I allowed to run again?” he said during a House Republican retreat in January.
