What statements or testimony has Mark Epstein given regarding Donald Trump's alleged sexual behavior?
Executive summary
Mark Epstein, Jeffrey Epstein’s brother, has publicly said his late brother claimed to have “dirt on Trump” but did not specify what that meant; Mark repeated that Jeffrey “definitely had dirt on Trump” without detailing it [1]. Congressional document releases and media reporting in November 2025 show emails and other materials in which Jeffrey Epstein wrote that Trump “knew about the girls,” but those documents do not, by themselves, prove criminal conduct by Trump and Trump has denied wrongdoing [2] [3] [4].
1. Mark Epstein’s central claim — “Jeffrey had dirt on Trump”
Mark Epstein told television interviewers and media that his brother Jeffrey said he had compromising information on Donald Trump, and Mark said Jeffrey “definitely had dirt on Trump,” while also acknowledging he was not told the substance of that information [1]. The publicized quote is an allegation about what Jeffrey claimed to possess, not sworn evidence of Trump’s conduct; the available sources show Mark framed his statement as reporting what Jeffrey told him rather than presenting documents or testimony proving specific acts [1].
2. How journalists and Congress have contextualized Mark’s remarks
News organizations and House Democrats released tens of thousands of Epstein-related documents in November 2025; those materials include emails that Democrats say raise questions about Epstein’s ties to Trump and statements such as Epstein asserting Trump “knew about the girls” [2] [5]. Reporting emphasizes that selections from those files were highlighted by Democrats to suggest lines of inquiry; Republicans and some commentators caution the released items do not definitively establish criminal wrongdoing by Trump [2] [4].
3. What Mark Epstein’s statements are not — legal proof or detailed testimony
Mark Epstein’s public comments, as reported, are not a deposition or sworn testimony alleging specific acts by Trump; they are descriptions of what Jeffrey allegedly told Mark [1]. Available sources do not show Mark producing emails, documents, or a sworn affidavit that directly details Trump’s alleged sexual behavior; they note his statement is an assertion about Jeffrey’s claims rather than an evidentiary account [1].
4. Competing interpretations in public reporting
Democrats and some media outlets have used released emails and Mark’s comments to argue the record warrants further investigation into what Epstein knew about powerful figures, including Trump [2] [5]. By contrast, Republicans and outlets sympathetic to Trump have argued that the documents “neither concretely prove nor disprove” Trump’s awareness of Epstein’s crimes and have framed some disclosures as politically motivated or incomplete [4] [6]. Both lines of argument appear in the public record provided.
5. What the released Epstein documents actually say about Trump
The documents and emails released by House Democrats include items in which Jeffrey Epstein asserted that Trump “knew about the girls,” and other notes in which Epstein discussed how to address media questions about his relationship with Trump [2]. Reporting also shows Trump’s name appears in multiple documents and communications, sometimes in nongermane political or social contexts, and that mere mention in the files does not equate to proof of criminal conduct [3] [5].
6. Limitations of the public record and outstanding questions
Available sources show gaps: Mark Epstein’s statements do not specify the alleged “dirt”; the released files have been curated by congressional staff and are subject to differing redactions and partisan interpretations; and mainstream reporting underscores that no court has established Trump’s participation in Epstein’s trafficking operation [1] [3] [7]. The sources also note that some materials remain sealed or were previously subject to court orders, limiting what the public record currently establishes [3] [5].
7. What to watch next
Investigative threads to follow include whether Mark Epstein or others provide corroborating documents or sworn testimony, whether additional unredacted files emerge from congressional or judicial processes, and how both parties in Congress and the Justice Department respond to demands for further release or inquiry [5] [3]. Media outlets and congressional Republicans are already disputing selections and context of the releases, indicating legal and political battles over interpretation will continue [4] [6].
Final assessment: Mark Epstein has publicly relayed that Jeffrey Epstein claimed to possess compromising information about Donald Trump but did not provide specifics; contemporaneous document releases include emails that raise questions about Trump’s knowledge of Epstein’s conduct, yet the materials released so far and Mark’s comments stop short of producing judicial proof of specific sexual wrongdoing by Trump in the public record [1] [2] [4].
