“I’m not joking,” Trump told Welker, reiterating, “It is far too early to think about it.”

Trump has frequently teased a third term, saying at rally in Nevada in January that “it will be the greatest honor of my life to serve, not once but twice or three times or four times,” apparently joking. He later clarified: “No, it will be to serve twice. For the next four years, I will not rest.”

Weeks later, Trump asked supporters during a Black History Month event at the White House whether he should run again, prompting chants of “Four more years!”

But Steve Bannon, a top outside ally to the president, has suggested that Trump is eligible since the amendment doesn’t specify “consecutive” terms.

In the House, Rep. Andy Ogles, a Tennessee Republican, has introduced legislation to begin the long process of tweaking the text of the 22nd Amendment and allowing a president who serves nonconsecutive terms to serve a third four-year term. The wording of Ogles’ proposal would exclude two-term former presidents such as Barack Obama from coming out of retirement.

Repealing or changing the 22nd Amendment would require two-thirds votes in both the House and the Senate and the ratification by three-quarters of the states. The only president to serve more than two terms was Franklin D. Roosevelt. The 22nd Amendment was ratified in 1951, in the years following Roosevelt’s death in office.

“It’s illegal. He has no chance. That’s all there is to say,” Michael Waldman, president and CEO of the Brennan Center for Justice at New York University’s law school, told CNN last month.

At the end of his second term in January 2029, Trump will be the oldest person to ever hold the presidency at 82 years and 7 months old, topping his predecessor Joe Biden’s record. Biden was 82 years and 2 months old when he left office.
