Leon Black, the co-founder of Apollo Global Management, sues the U.S. Congress to block House committee subpoenas related to the Jeffrey Epstein investigation. The legal filing comes after Black does not appear for a sworn deposition scheduled for Thursday.

According to reporting, the dispute centers on demands for information that may relate to nondisclosure agreements Black may have made with women. Black’s lawsuit asks the committee court intervention to prevent enforcement of those subpoenas. The New York Times and Quartz both describe the deposition refusal and the timing of the suit but focus on different procedural details and framing of the committee’s requests.

Overall, the sources agree that Black challenges Congress’s authority or the subpoenas’ scope and that he does so in federal court rather than through continued compliance with the committee’s deposition notice. The outlets’ differences mainly concern how the subpoenaed materials are characterized, including references to nondisclosure agreements, rather than the core sequence of events: skipped deposition, lawsuit filed, and efforts to stop congressional information demands.
