Russell Horwitz, Goldman Sachs' outgoing chief of staff, repeatedly challenged CEO David Solomon's support for Kathy Ruemmler, the former general counsel linked to Jeffrey Epstein. Three sources say Horwitz raised concerns for months as Department of Justice documents revealed Ruemmler's continued interactions with Epstein until months before his 2019 death. The disagreement exposed deep divisions within the bank's senior ranks.

Ruemmler announced in February she would leave her roles as general counsel and chief legal officer, calling her Epstein ties a "distraction." However, Solomon recently asked her to remain in an advisory capacity, shocking colleagues. The DoJ documents showed Epstein lavished gifts on Ruemmler, including a 2019 email where she wrote she was "totally tricked out by Uncle Jeffrey today!" Ruemmler maintains she regretted knowing Epstein and was unaware of his criminal activities.

Horwitz's departure at month-end highlights succession uncertainty at Goldman. He was widely viewed as potential successor to John Rogers, the influential board secretary. Horwitz previously left in 2020 but returned as partner in 2023, taking on Rogers' responsibilities. His exit removes a senior voice questioning Solomon's judgment on personnel decisions.

The controversy raises questions about Goldman's risk management and board oversight. With Ruemmler staying on in an advisory role despite Epstein revelations, investors may scrutinize whether the bank adequately addressed reputational risks in its highest ranks.
