Russell Horwitz, Goldman Sachs' chief of staff, is walking out the door at the end of June, and the reason he won't give may matter more than the one he does.
Horwitz spent months privately pushing back against CEO David Solomon's decision to stand by Kathy Ruemmler, a close adviser whose ties to convicted sex offender Jeffrey Epstein became impossible to ignore after the Justice Department released a batch of Epstein-related emails. Ruemmler resigned in February. But Solomon kept reaching for her hand on the way out, and Horwitz, by multiple accounts, kept objecting.
Now Horwitz is gone. He denies the Ruemmler saga drove his exit. The timeline tells a different story.
The Financial Times reported Monday that Horwitz was among the few senior Goldman executives willing to confront Solomon over his continued backing of Ruemmler as successive document releases exposed the depth of her relationship with Epstein. One person familiar with the situation told the FT plainly:
"Russell was one of the few people who wanted to address it and everyone else didn't. That was hugely frustrating for him."
A source close to the situation confirmed to the New York Post that the FT's reporting was accurate. Solomon's defense of Ruemmler had become, in the FT's description, a "taboo subject" inside Goldman, the kind of thing people knew better than to raise with the boss.
Horwitz apparently did not get that memo. Or chose to ignore it.
The timeline here is worth tracing carefully. Ruemmler resigned in February after the Justice Department's release of Epstein-related emails made her position untenable. Solomon said at the time that he "reluctantly accepted" her departure and called her work "tremendous."
That should have been the end of it. It wasn't.
The Post reported in April that Solomon privately urged Ruemmler to reconsider her resignation, telling her directly: "You don't have to do this." And the FT reported that Solomon went further still, asking Ruemmler to stay on as an adviser to the firm beyond her scheduled departure date later this month.
So the CEO of one of the largest banks in the country watched Epstein-related documents pile up, watched his adviser resign under pressure, and then spent the next several months trying to pull her back in. Horwitz raised objections. Horwitz is the one leaving.
Sources close to Ruemmler have told the Post that she was transparent with Goldman about her Epstein ties before she ever joined the bank. They also said she turned down an offer worth $30 million to join Epstein's defense team after his 2019 arrest. Ruemmler herself has maintained that she regretted ever knowing Epstein and had no knowledge of his criminal activities.
Those claims have not been independently verified. But even if taken at face value, they do not explain why Solomon fought so hard to retain her after the document releases made the association a live political and reputational liability.
Goldman Sachs and representatives for Ruemmler declined to comment when reached by the Post.
Horwitz, for his part, offered a narrow denial when asked whether the Ruemmler controversy prompted his departure:
"No, that is not the reason I'm leaving Goldman Sachs."
He did not say what the reason was. The Post has sought additional comment from him.
Meanwhile, a source described by the Post as close to the situation reacted to the FT's reporting with a different kind of frustration, saying they were "shocked and appalled that an executive would talk about disagreements with the CEO." That response is revealing in its own right. The concern was not that the disagreement happened. The concern was that someone talked about it.
The internal tension at Goldman did not stay internal for long. Sen. Elizabeth Warren and Rep. Raja Krishnamoorthi, both Democrats, wrote a letter to Solomon arguing that his decision to retain Ruemmler should "call into question" his "professional judgement and fitness to continue leading one of the largest banks in the United States." Bloomberg News reported on the letter.
When a Democratic senator and a Democratic congressman are questioning whether a Wall Street CEO has the judgment to run his own firm, and the CEO's own chief of staff was raising similar concerns behind closed doors, the problem is no longer a personnel dispute. It is a governance question.
Warren and Krishnamoorthi are not natural allies of Goldman Sachs shareholders. But the substance of their complaint lines up with what Horwitz was reportedly saying privately for months: Solomon's loyalty to Ruemmler was becoming a liability that the bank could not afford.
David Solomon built his reputation as a hands-on CEO willing to shake up Goldman's culture. He has weathered criticism before. But the Ruemmler episode raises a harder question than whether Solomon is loyal to his people. The question is whether that loyalty overrode his obligation to the institution he runs.
The Justice Department released Epstein-related emails. Ruemmler resigned. Solomon told her she didn't have to go. He asked her to stay on as an adviser. His chief of staff objected, for months, and is now the one heading for the exit.
Goldman declined to comment. Ruemmler's representatives declined to comment. Horwitz offered a one-sentence denial that answered nothing.
The facts that remain on the table are not complicated. A senior Goldman executive challenged the CEO's judgment on a matter involving a convicted sex offender's associate. The executive who raised the concern is the one who lost his seat.
On Wall Street, that kind of outcome sends a message, and it is not the one Goldman's shareholders should want to hear.
