On Tuesday, mourners gathered in Pittsburgh to honor the victims of the harrowing attack on the Tree of Life synagogue. Days earlier, as they observed Shabbat, 11 Jews were murdered. Robert Bowers, the alleged suspect, later told a SWAT officer that he wanted all Jews to die. (Bowers has since pleaded not guilty.) The tragedy united thousands of Jews in Pittsburgh, who peacefully protested Donald Trump’s visit to the synagogue earlier this week. It also consumed a far larger constituency, which remained aghast that the alleged killer was motivated by fear fanned by the president of the United States.

Michael Cohen, the president’s former lawyer, was among those closely following the story. The son of a Holocaust survivor, Cohen has remained largely silent since the F.B.I. executed search warrants on his home, hotel room, and office this past spring. In August, he pleaded guilty to charges related to campaign-finance violations and tax fraud, and at the advice of counsel, he has not spoken publicly about his case or his relationship with the president ever since. Privately, he has been cooperating with investigators in the Southern District of New York, the special counsel’s office, and New York State. (He faces sentencing in the Southern District next month.) Yet Cohen wanted to express himself in the wake of the tragedy. Shortly after the sun rose on Tuesday, he tweeted, “In honor of those sadly being buried today resulting from #AntiSemitism #PittsburghSynagogueShooting, let’s follow the wisdom and thoughtful words of #RabbiJeffreyMyers ‘it can’t just be to say we need to stop hate. We need to do, we need to act to tone down rhetoric.’”

Like many, Cohen has observed the president’s scorched-earth campaign tactics as the midterm elections approach, and as the prospect of a Democratic House majority beckons, with its attendant promise of investigations and inquiries. He has heard Trump’s constant invocation of the migrant caravan moving through Central America; he’s noticed the president threaten to revoke birthright citizenship; he’s noted Trump’s tweet calling Florida’s African-American gubernatorial candidate, Andrew Gillum, a “thief,” without any evidence. He also watched Trump shirk responsibility after it was discovered that Bowers invoked the caravan in posts online ahead of the mass murder in Pittsburgh, and after one of his ardent supporters was charged last week with mailing pipe bombs to notable Democrats and other frequent Trumpian targets. (The suspect plans to plead not guilty.) On Twitter and during rallies, Trump has referred to the media as “the enemy of the people,” blaming the free press for “the anger we see today in our society.”

That message rang hollow to those most familiar with the president and his language, including Cohen, who said he has spent the last several months quietly reflecting on his former boss and his own role in the Trump Organization. Amid the president’s recent tirades, Cohen has re-registered as a Democrat and urged people on Twitter to vote in the midterm elections, calling it possibly “the most important vote in our lifetime.” He said that events also activated within him an urge to reveal details from his tenure at the Trump Organization, during which he said the president privately uttered chilling, racist language in one-on-one conversations. On Tuesday, the day of the first funerals in Pittsburgh, he shared some of these memories.

Certainly, Cohen is aggrieved, and his credibility has been questioned by the president, his lawyers, and others. His allegations could inflame the very divisions that he’s said he wants to diffuse. Through the president’s public attacks against him, he stayed silent, as his lawyers advised, and he’s taken a risk in sharing these recollections on the record. When I asked him why he was coming forward now with such uncomfortable claims, Cohen was clear: he knew that the president’s private comments were worse than his public rhetoric, and he wanted to offer potential voters what he believed was evidence of Trump’s character in advance of the midterm elections.
