Trump has told his lawyers that Bolton should not be allowed to publish any of his interactions with him about national security because they are privileged and classified, these people said. He has also repeatedly brought up the book with his team, asking whether Bolton is going to be able to publish it, they said.

Trump told national television anchors on Feb. 4 during an off-the-record lunch that material in the book was “highly classified,” according to notes from one participant in the luncheon. He then called him a “traitor.”

“We’re going to try and block the publication of the book,” Trump said, according to the notes. “After I leave office, he can do this. But not in the White House.”
