ABC News’ Jonathan Karl on Tuesday said President Donald Trump has “started doing this thing” on board Air Force One where he goes around asking people: “JD or Marco? JD or Marco? JD or Marco?”

It’s a reference to whether Vice President JD Vance or Secretary of State Marco Rubio should be his successor.

Karl pointed to Trump’s question as evidence that the president doesn’t really have “any designs on actually staying past the end of this term” despite his repeated talk of and hints at trying to stay in the White House for an unconstitutional third term.

Trump “tells people privately, people close to him, ‘No, no, I’m, you know, I’m done,’” Karl said on Tuesday’s broadcast of MSNBC’s “Morning Joe” while promoting his new book, “Retribution: Donald Trump and the Campaign That Changed America.”

Karl said Trump is “absolutely trolling” with his 2028 talk.
