WASHINGTON (Reuters) — Republican President Donald Trump stated on Sunday that he was not joking about pursuing a third presidential term, which is prohibited by the US Constitution, but said it was too early to consider doing so.

Trump, who began his second, non-consecutive term in the White House on January 20, has made vague allusions to pursuing a third, but addressed the issue openly in a phone interview with NBC News on Sunday.

“No, I’m not kidding.” “I’m not kidding,” Trump remarked, “but it’s far too early to think about it.”

“There are, there are methods which you could do it, as you know,” he told me. He declined to expand on particular approaches.

According to the 22nd Amendment to the United States Constitution, presidents can serve just two four-year terms, either consecutive or not.
