Leon Black Sues House Committee to Block Epstein Subpoenas

Billionaire investor Leon Black filed a federal lawsuit on Thursday, September 3, 2026, against the House Oversight Committee, seeking to block subpoenas issued as part of its investigation into the late financier Jeffrey Epstein. Black simultaneously refused to appear for a sworn deposition before the committee, prompting lawmakers to call for immediate contempt proceedings. The legal action escalates a months-long dispute between Black, the co-founder and former CEO of Apollo Global Management, and the congressional panel. The conflict stems from a voluntary, closed-door interview Black gave to the committee on June 26. According to multiple sources, that session ended abruptly after Black declined to answer questions about nondisclosure agreements connected to Epstein. In response, the committee issued two subpoenas: one demanding Black produce NDAs and related documents, and another compelling him to return for a formal deposition. Black’s lawsuit argues the subpoenas are invalid, claiming the committee has exceeded its authority by seeking private information that bears no legitimate connection to its legislative work.
