DOJ-OGR-00021304.jpg

This document page outlines the Department of Justice hierarchy in early 2008 and details a specific period of review by the Child Exploitation and Obscenity Section (CEOS). It recounts a February 21, 2008 conversation where CEOS Chief Andrew Oosterbaan told attorney Lefkowitz that CEOS could take a 'fresh and objective look' at the case rather than partnering with the USAO, provided that would help the process move forward.

DOJ-OGR-00021303.jpg

This page from a DOJ OPR report details the internal Department review between February and June 2008 regarding the Epstein case. It highlights that while Epstein's defense sought a broad review of misconduct and NPA terms, the DOJ only reviewed federal jurisdiction issues. The document also records a 'stand down' order where Oosterbaan instructed a CEOS attorney to cease involvement, and details the formal notification sent by the USAO to the Civil Rights Division classifying the case as 'child prostitution' rather than a matter of 'national interest.'

DOJ-OGR-00021227.jpg

This document details internal discussions within the U.S. Attorney's Office in Miami during May-June 2007 regarding the Jeffrey Epstein case. It describes how prosecutor Villafaña submitted a memorandum seeking to file charges by May 15, but her managers, including Sloman, Menchel, and Lourie, paused the process to conduct a more thorough review, including seeking analysis from the DOJ's CEOS section. The document highlights the tension between the desire to move quickly on the indictment, as pushed by the FBI, and the managers' more cautious approach, which ultimately delayed the charges.

DOJ-OGR-00003262.jpg

This document is a page from a DOJ OPR report detailing internal conflicts within the USAO in August 2007 regarding the Epstein investigation. Prosecutor Marie Villafaña urged for continued investigation, specifically a trip to New York to interview employees and efforts to seize Epstein's computers, citing a recent interview with a victim recruited at age 14. However, US Attorney Alexander Acosta prioritized maintaining control of the case over DOJ intervention, leading to delays in investigative steps and a stay in litigation to accommodate meetings with Epstein's defense team.

DOJ-OGR-00002972.jpg

This document is page 38 of a legal filing in United States v. Ghislaine Maxwell (Case 1:20-cr-00330). The government argues that the Non-Prosecution Agreement (NPA) signed by the USAO-SDFL with Jeffrey Epstein did not bind other districts. It cites the November 2020 DOJ Office of Professional Responsibility (OPR) report, noting that while USAO-SDFL prosecutor Maria Villafaña consulted with DOJ Child Exploitation Chief Andrew Oosterbaan, this does not support the defendant's claim of a wider immunity promise.
