Donald Trump on Sunday repeated his suggestion he might seek a third term as president, which would defy the two-term limit stipulated in the US Constitution.

In a Sunday morning phone call with NBC News, Trump said, "I'm not joking," when asked to clarify a remark on seeking another term, adding, "There are methods which you could do it." The 78-year-old billionaire has a long history of suggesting he might serve more than two terms, but Sunday's remarks -- followed by comments to reporters aboard Air Force One -- were the most concrete in terms of referring to plans in place to achieve the goal.

Trump has launched his second presidency with an unprecedented demonstration of executive power, using the world's richest man, Elon Musk, to dismantle swaths of the government, and said his supporters want even more. "We have almost four years to go and that's a long time, but despite that, so many people are saying you've got to run again.

They love the job we're doing," Trump said Sunday aboard the presidential jet, apparently referring to his political allies and supporters.
