Sources: 19. Developments: 2. Leon Black, the billionaire investor and former CEO of Apollo Global Management, is facing intense scrutiny regarding his financial relationship with Jeffrey Epstein. In early September 2026, Black filed a federal lawsuit to block subpoenas from the House Committee on Oversight and Government Reform. The committee is investigating ties between Epstein and various influential figures, seeking testimony and nondisclosure agreements held by Black. Black’s legal team has characterized the investigation as a ‘fishing expedition’ that exceeds congressional authority, with attorney Susan Estrich stating the probe is ‘trying to destroy Mr. Black’ rather than seeking the truth. In response, lawmakers have considered holding Black in contempt of Congress. Simultaneously, the nature of Black’s ties to Epstein has become a focal point of public discussion. During a talk regarding the biography ‘Money to Burn’, author William Cohan noted that Black reportedly paid Epstein millions of dollars during the latter’s final years. Cohan described the situation as “complicated,” noting that Epstein’s death makes it difficult to fully uncover the specific nature of these payments. ## Timeline ### 2026-09-10: Leon Black’s ties to Jeffrey Epstein remain central to new biography Biographer William Cohan addressed the unresolved questions regarding Leon Black’s multi-million dollar payments to Jeffrey Epstein during a book event in Manhattan. 2 sources. https://clstr.news/cluster/leon-blacks-ties-to-jeffrey-epstein-remain-central-to-new-biography ### 2026-09-03: Leon Black sues House Oversight Committee over Epstein probe subpoenas Billionaire Leon Black has sued the House Oversight Committee to block subpoenas related to the Jeffrey Epstein investigation, prompting calls from lawmakers for contempt charges. 17 sources. https://clstr.news/cluster/leon-black-sues-house-oversight-committee-to-block-epstein-probe-subpoenas --- Cite as: Leon Black investigation into Jeffrey Epstein ties.
