People who know Gary Cohn were first surprised, then relieved, when he announced that he would be joining the Trump administration. For one, Cohn has been a life-long Democrat. For another, the former Goldman Sachs president was known as a direct, no-nonsense operator whose management style would seem to conflict with Donald Trump’s preference for chaos. Banks like Goldman Sachs had, in fact, shunned Trump’s business for years, refusing to lend him money. On the campaign trail, Trump railed against Goldman Sachs and even dropped an allegedly anti-Semitic advertisement painting Goldman C.E.O. Lloyd Blankfein’s as the face of a “global power structure responsible for the economic decisions that have robbed our working class.”

But at least Cohn would be a moderating force and a steady hand in an administration sorely lacking in both, the thinking went. (“Trump loves having Goldman guys around,” a source told Gabriel Sherman last December. “The bank wouldn’t touch Trump, and now they’re working for him.”) For a while, the former real-estate developer was almost deferential toward Cohn, who had “walk-in privileges” and was allowed to interrupt Trump to offer his take on a situation. Trump reportedly loved that Cohn was a “guy’s guy,” and the fact that he had the experience of running an organization that employed thousands of people, plus a “self-assured confidence” put him at the top of Trump’s list of trusted associates, just below those related to him.

Unfortunately, like many Trump romances, this one has hit the skids. Trump quickly proved to be the sort of undisciplined employee who would’ve been fired from Goldman Sachs on day one. He withdrew the United States from the Paris climate agreement, despite Cohn’s protestations. The breaking point was Charlottesville: Cohn was said to be “disgusted” and “dismayed” at his boss’s characterization of a group containing neo-Nazis as having some “very fine people,” and, after two weeks of stewing, let his thoughts be known in an interview with the Financial Times, wherein he condemned the president’s equivocating. Not surprisingly, it did not go over well.

The Washington Post reports that Trump is “simmering with displeasure over what he considers personal disloyalty from Cohn.” While he has so far resisted his impulses to fire the National Economic Council director, knowing that Cohn is effectively the face of the White House’s tax-reform effort, he has “found other ways to slight him,” including using the beginning of his tax speech in Missouri on Wednesday to give shout-outs to “the many distinguished guests” present but failing to mention Cohn. And because this is a family business, the Post notes that Ivanka Trump, who, along with her husband, Jared Kushner, was influential in bringing Cohn into the fold, “tweeted a call for tax reform with a picture of Trump backstage flanked by her and Mnuchin. Notably absent was Cohn.”

Asked later about the state of the Cohn-Trump relationship aboard Air Force One, Press Secretary Sarah Huckabee Sanders told reporters only that the two were committed to passing tax-reform legislation. Meanwhile, Trump has apparently been making calls “on his personal phone” to former White House strategist and Cohn-nemesis Steve Bannon, when Chief of Staff John Kelly isn’t around:
