The trustees of Jeffrey Epstein’s estate are expected to begin producing documents to House Oversight Committee investigators on Monday pursuant to a subpoena that sought a wide range of materials tied to Epstein and his longtime associate Ghislaine Maxwell.

Committee Chairman James Comer, R-Ky., subpoenaed the estate on Aug. 25 and requested the records be delivered by Sept. 8. The subpoena seeks all entries in a book compiled by Maxwell for Epstein’s 50th birthday, Epstein’s will, records related to his 2008 non-prosecution agreement with federal prosecutors, and documents reflecting financial transactions, phone and visitor logs, and any materials that could be construed as listing clients involved in sex trafficking or related sex acts.

A committee aide said investigators expected the first tranche of documents on Monday but did not specify what that initial production would include. An attorney for the executors of Epstein’s estate has said the co-executors will comply with all lawful process, including the committee’s subpoena.

Comer has pursued materials from a range of sources as part of the panel’s continuing probe into Epstein and Maxwell, and has subpoenaed individuals and government entities, including the Department of Justice. The chairman has also scheduled a transcribed interview with Alexander Acosta, the former labor secretary and previously the U.S. attorney for the Southern District of Florida when Epstein entered into the 2008 non-prosecution agreement; the interview is set for Sept. 19.

Lawmakers and investigators have said the so-called "birthday book" may shed light on Epstein’s personal connections. The item, compiled in 2003 for Epstein’s 50th birthday, contains personalized messages from friends and associates, but investigators acknowledge the information it contains is likely to be dated.

The House Oversight Committee has already released roughly 33,000 pages of files turned over by the DOJ, though committee officials have said much of that material had been previously public. Comer and other panel members met recently with survivors of Epstein’s abuse as part of the committee’s effort to gather information and inform potential legislative responses.

Committee officials have emphasized the investigation’s dual aims of uncovering documents that could inform accountability and shaping potential changes to law and oversight practices. The estate’s cooperation with the subpoena marks the next step in the House inquiry as investigators review the materials to determine whether further depositions, interviews or subpoenas are warranted.

Representatives for the estate and for the House panel did not provide additional detail about the scope of Monday’s production. The committee’s work remains ongoing, and officials have said they intend to pursue additional records and testimony as the review continues.
