If there‘s one person whose name is likely sending shivers down Donald Trump’s spine at the moment, it’s that of his mustachioed former national security adviser, John Bolton. While Bolton has yet to testify before the House, it would appear that if and when he does, he’ll have a cornucopia of illuminating information to share with lawmakers as part of their investigation into Trump’s attempt to extort Ukraine, given that the former adviser seemingly knows where all the bodies are buried and kept notes. Last month, we learned that Bolton told an aide to make it known to a deputy White House Counsel that he wanted no part of “whatever drug deal [E.U. ambassador Gordon] Sondland and [acting White House chief of staff Mick] Mulvaney” were “cooking up,” and in a teaser re: what he could share about said drug deal, Bolton’s lawyer told lawmakers that his client was “personally involved in many of the events, meetings, and conversations about which you have already received testimony, as well as many relevant meetings and conversations that have not yet been discussed in the testimonies thus far.” And just to keep things interesting, the ex-NSC adviser has reportedly been dishing on his ex-boss.

According to NBC News, Bolton used his appearance last Wednesday at Morgan Stanley’s global investment event in Miami to mock Ivanka Trump and Jared Kushner and suggest Trump’s approach to Turkey is “motivated by personal or financial interests,” according to a number of people who were present for the remarks. While the details were scant, one assumes that Bolton shared a low opinion of Trump’s son-in-law inserting himself in matters of foreign policy despite having literally no relevant experience whatsoever. When it comes to Ivanka, perhaps he offered his take on the first daughter’s endorsement of former national security council adviser turned felon Mike Flynn, or the manner in which she and her husband obtained their top security security clearances. As for Trump—who has property in Turkey— the notion that he would put his own interests above those of national security is not hard to believe for anyone who’s ever heard of the guy, who’s made it abundantly clear that his only principle in life is “how does this benefit me?”

The description was part of a broader portrait Bolton outlined of a president who lacks an understanding of the interconnected nature of relationships in foreign policy and the need for consistency, these people said.

While multiple people who attended the private speech told NBC News they did not recall Bolton mentioning Ukraine, one could see how “this guy is only in it for himself” would apply not just to Turkey but perhaps to a situation in which one was in a position to lean on a certain Eastern European country to investigate his political rival, in the hopes that it would help him out in 2020. Bolton, who declined to comment, did tell attendees that he kept a resignation letter in his desk for three months, which may or may not have had to do with his anger re: the shadow Ukraine campaign, if the testimonies of former aides are anything to go by.
