What we’re hearing: Republican senators and their aides are frustrated about the way the Bolton manuscript leaked, with some privately venting suspicions that White House Counsel Pat Cipollone must have known about its contours before a Saturday presentation on the Senate floor during which Trump’s defense team asserted there was “no evidence anywhere” that Trump linked Ukraine aid to any investigations.

“I don’t see how it’s possible he didn’t,” one GOP aide told Axios. “My boss was pissed to read about it in the Times.”

A spokesman for the White House National Security Council said in a statement Monday that Bolton’s manuscript had been submitted to the NSC for pre-publication review but that “no White House personnel outside the NSC have reviewed the manuscript.”
