Andrew Oosterbaan

Snapshot

Introduction

Andrew G. Oosterbaan appears in the Epstein record as a federal lawyer who supported the legal basis for prosecution and later explained the limits of a Justice Department review. His work included advice to Florida prosecutors in 2007 and a signed response to Epstein’s defense team on May 15, 2008. The original letter is a legal assessment, not a court judgment or an approval of every part of the nonprosecution agreement.

This profile follows his documented role from the initial charging review through the defense appeal in June 2008. It also includes his later account to the Office of Professional Responsibility, or OPR. The differences matter. Offering help with a case, receiving a draft agreement, and approving the final agreement are different acts.

Key Takeaways

• In May and July 2007, CEOS supported the proposed federal charging analysis while recognizing legal questions that could require more research or a court’s decision. OPR report, pages 27 and 47.
• The record includes Oosterbaan’s support for consulting victims, his receipt of a draft agreement, and correspondence about a possible victim fund. These details qualify any claim that his role concerned charging law alone. OPR report, pages 61 to 64; September 13 email.
• His May 15, 2008 letter concluded that Acosta could authorize a federal prosecution. It expressly excluded review of the plea offer and misconduct allegations. Letter, pages 1 to 5.
• Epstein’s lawyers challenged the review as too limited and sought senior intervention. The Deputy Attorney General’s office declined to intervene on June 23, 2008. Defense letter, pages 1 and 2; OPR report, page 110.

Professional Background and Identity

The Justice Department’s November 14, 2001 appointment announcement identifies Andrew G. Oosterbaan as the new chief of CEOS. He had been its deputy chief since January 2000 and previously spent nearly ten years as an assistant U.S. attorney in the Southern District of Florida. His government title and full name also appear on the May 2008 letter. The September 2007 email chain addresses the same CEOS official as Drew. The name, title, and email context all match. A surname or archive tag alone would not prove his identity.

The 2007 Legal Review

On May 10, 2007, Andrew Lourie sent Ann Marie Villafaña’s prosecution memorandum to Oosterbaan with the agreement of Matthew Menchel, chief of the Florida office’s Criminal Division. Oosterbaan referred it to his deputy and another CEOS lawyer. According to OPR’s account on report page 27, the section agreed with Villafaña’s analysis. One issue needed more research: whether some laws required proof that a defendant knew a victim’s age. Oosterbaan offered to assign a CEOS lawyer to help.

On July 18, Oosterbaan emailed Jeffrey Sloman, Menchel, and Lourie that the proposed charges were legally sound. He recognized that some defense arguments deserved close consideration but believed the balance of precedent favored prosecution. He again offered staff and assistance. This was support for a case that could be brought, not a finding that every disputed fact had been proved. OPR report, page 47; EFTA02830848.

On August 31, Oosterbaan traveled to West Palm Beach to review the file with Villafaña and the case agents before a meeting with the defense. OPR places that defense meeting on September 7, 2007. The checked government timeline lists the same date. OPR report, pages 61 and 62; timeline page 12; EFTA00225439.

Victim Consultation and Agreement Discussions

In a September 6 email quoted by OPR, Villafaña told Sloman that Oosterbaan had reminded her to seek victims’ input before resolving the case. Sloman forwarded her message to Acosta. OPR cautioned that the email’s reference to victim approval overstated the statute: consultation and consent are different requirements. It also described the Department’s position at the time that the statutory duty did not apply before federal charges. OPR report, pages 61 and 62; pages 204 and 205.

Oosterbaan later told OPR that victims should have had a chance to express their views regardless of whether the law required it. He disagreed with the Florida office’s approach but regarded the issue as a legitimate legal and policy dispute, rather than evidence that his colleagues intended to act improperly. He also said he might have pressed the issue more strongly. These are his later views as reported by OPR, not a separate court ruling. OPR report, pages 205 and 206; EFTA02831006 and EFTA02831007.

The record also shows that Villafaña sent him a revised nonprosecution agreement on September 11. Oosterbaan responded to the continued counteroffers, but later told OPR he did not recall reading that draft and denied involvement with it at that stage. On September 13, he offered to ask prosecutors about a victim fund used in another case and to finish reviewing the proposed indictment. That email documents advice and a promised inquiry. It does not establish that he designed or approved the final compensation terms. OPR report, page 64, note 105; September 13 email, EFTA00191174.

A late November 2007 exchange adds another qualification. OPR reports that Oosterbaan thought the agreement favored Epstein too much and offered victims little help. He also said Assistant Attorney General Alice Fisher should not revisit it except to agree with it. Fisher later told OPR that she understood the reference to agreement to concern federal prosecution; she said she neither reviewed nor approved the nonprosecution agreement. The report preserves both accounts. It does not support describing Oosterbaan as having no contact with the agreement or treating Fisher’s approval as established. OPR report, page 95; EFTA02830896.

How the 2008 Review Was Defined

The section’s role changed in early 2008. OPR records that Oosterbaan stopped a CEOS trial lawyer’s work on the prosecution as the section undertook the requested Criminal Division review. On February 21, he discussed the distinction with Lefkowitz. By February 25, Lefkowitz had agreed that CEOS would serve as reviewer rather than join the prosecution team. OPR report, pages 103 to 105; EFTA02830904 to EFTA02830906.

On March 12, Oosterbaan, Deputy Assistant Attorney General Sigal Mandelker, and a CEOS deputy heard the defense’s presentation. OPR describes later defense submissions and says the deputy drafted the response letter, with input from Mandelker, Fisher, the Appellate Section, and the Office of Enforcement Operations. Oosterbaan signed the resulting letter. This was a section review with broader Department input, not a personal decision made without consultation. OPR report, pages 106 and 107.

The Signed May 15, 2008 Letter

The five-page letter is addressed to Jay Lefkowitz, dated May 15, 2008, and signed above Oosterbaan’s printed name and title. It is preserved as document 403-8, court pages 2 to 6, in Doe v. United States, No. 9:08-cv-80736. The reviewed compilation places those pages at PDF pages 97 to 101. Original letter and signature.

The letter says the review considered defense letters and attachments, prosecution memoranda, the defense meeting, and advice from other Criminal Division offices. It asked whether Acosta could properly exercise his discretion to prosecute. Its conclusion was that “federal prosecution in this case would not be improper or inappropriate.” It left the charging choice with the U.S. attorney. Letter, pages 1 and 5.

The letter addressed knowledge of age, travel and intent, and use of interstate communications. It also considered witness credibility, the search warrant, and federal enforcement policy. It rejected the defense position that lack of force or coercion automatically barred a child sex trafficking charge. These were the Department’s legal assessments in 2008. They were not jury findings about Epstein’s guilt. Letter, pages 2 to 4.

The limits were explicit. The section did not start a new factual investigation, analyze unrelated federal offenses such as money laundering, review the facts or terms of the plea offer, or investigate alleged prosecutorial misconduct. Calling this letter a complete review of the nonprosecution agreement would overstate what the document says. Letter, pages 1 and 2.

Defense Response and the June 2008 Decision

On May 19, Kenneth Starr and Joe D. Whitley wrote to Deputy Attorney General Mark Filip. They said the review had been too narrow, challenged its standard, and requested a broader examination and an end to federal involvement. Their letter reports receiving Oosterbaan’s response on May 16. These were defense arguments, not findings that the review was improper. Signed defense letter, pages 1, 2, and 8; HOUSE_OVERSIGHT_025353, 025354, and 025360.

OPR records that senior official John Roth reviewed the written submissions for the Deputy Attorney General’s office. On June 23, he informed Starr and Lefkowitz that intervention was unwarranted and that the office considered federal prosecution appropriate. This was a later decision by that office, separate from Oosterbaan’s May letter. Epstein entered his state guilty plea on June 30, 2008. OPR report, pages 109 and 110; official executive summary, page ii.

Chronology

Evidence Appearances

Limitations and Responses

The reviewed sources do not show that Oosterbaan personally negotiated every term, signed the nonprosecution agreement, interviewed every witness, or directed the Florida office’s final charging decision. At the same time, his receipt of drafts and advice about a victim fund make it inaccurate to describe him as wholly removed from discussions about resolving the case.

His later statements to OPR are included where they qualify the contemporary record. OPR interviewed him, but its five designated subjects were Acosta and four Florida prosecutors. The report’s general misconduct conclusion should not be recast as a separate disciplinary decision about Oosterbaan. OPR report, executive summary page vi; report pages 4 to 6.

The full report was written roughly twelve years after the principal events and notes limits in participants’ memories. The original May letter and September email provide direct records; other events here rely on OPR’s review and quotations. The primary pages were checked in public copies, but this article does not claim to review every release or every later legal dispute. The scope of this documentary review is current through October 18, 2026.

Conclusion

Oosterbaan supported federal prosecution and gave advice during talks about resolving the case. He then led a limited review requested by the defense and the Florida office. His May 2008 letter found a permissible basis for prosecution while leaving the charging decision with Acosta. The letter should be read with its stated exclusions and with the earlier record of victim consultation and agreement discussions.

Questions and Answers

Who was Andrew Oosterbaan in the Epstein investigation?

He was the chief of CEOS, a specialized section in the Justice Department’s Criminal Division. He advised Florida federal prosecutors and signed the May 15, 2008 review letter. His role is documented by the official appointment announcement, contemporary correspondence, and the OPR report cited above.

Did his letter authorize or require an indictment?

It concluded that Acosta could properly choose federal prosecution. It did not require an indictment or replace the U.S. attorney’s charging authority.

Did he approve the nonprosecution agreement?

The May letter expressly excluded the plea offer’s terms from review. Separate records show that he received drafts, discussed a possible victim fund, and later commented on the agreement. Those acts do not by themselves establish that he approved its final terms.

What did he say about consulting victims?

Villafaña’s September 6 email cited his reminder to seek victim input. He later told OPR that victims should have been heard, while also describing the legal disagreement with the Florida office as legitimate. OPR distinguished consultation from a requirement to obtain victims’ consent.

Was his review the final Department response?

No. Epstein’s lawyers sought further review. On June 23, 2008, the Deputy Attorney General’s office separately declined to intervene.
