DOJ-OGR-00023138.tif

This document details efforts by Acosta to revise the Non-Prosecution Agreement (NPA) with language concerning monetary damages for victims of Jeffrey Epstein, which was ultimately rejected by the defense. It highlights disagreements and frustrations between prosecutors and defense counsel regarding the interpretation and implementation of the Section 2255 provision, particularly concerning victim notification and Epstein's alleged delays in his guilty plea.

Report excerpt

DOJ-OGR-00000533.jpg

This document is a page from a court transcript dated July 24, 2019. Attorney Mr. Weinberg argues that the timing of Epstein's arrest was suspicious relative to a CVRA filing in Florida. He asserts that high-level DOJ officials, specifically Alice Fisher (then Head of the Criminal Division) and Sigal Mandelker (currently Undersecretary of the Treasury), were directly involved in approving the controversial 2007 non-prosecution agreement.

DOJ-OGR-00021420.jpg

This document is a page from a DOJ report (likely OGR) detailing the period between January and June 2008 regarding the Jeffrey Epstein case. It describes the legal tug-of-war between Epstein's defense (Lefkowitz) and the USAO (Acosta) regarding victim notification under the CVRA, with the defense arguing federal notification was inappropriate. It also details internal DOJ reviews of the case evidence by senior officials (Senior, Oosterbaan, Mandelker, Fisher) which delayed the plea deal, while prosecutor VillafaƱa and the FBI continued to investigate potential federal charges in anticipation of an NPA breach.

This page from a DOJ OPR report details the conflict and confusion regarding victim notification in the Epstein case. It highlights discrepancies between USAO officials (Sloman, Acosta) and DOJ Criminal Division (Mandelker) regarding who decided to defer victim notification to state authorities. It also includes excerpts from Epstein's lawyer, Lefkowitz, aggressively arguing that federal victims had no standing in the state case and should not be contacted by the FBI or informed of 'fictitious rights.'

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-00021300.jpg

This document outlines the negotiations between US Attorney Alexander Acosta and Jeffrey Epstein's defense team (including Ken Starr and Jay Lefkowitz) regarding the language of the Non-Prosecution Agreement (NPA), specifically Section 2255 concerning victim rights and monetary damages. On December 19, 2007, Acosta proposed revised language to clarify victim rights as if Epstein had been convicted federally, but the defense rejected this, arguing it was legally incongruous to fit a civil statute into a criminal plea. The document highlights the mounting frustration of the prosecution regarding what they perceived as intentional delays by the defense.

It describes the prosecution, led by Acosta and VillafaƱa, engaging with Epstein's defense counsel, Gerald Lefcourt, over the terms of a plea deal. The focus of the negotiations shifted to the length of imprisonment, with the USAO moving from a two-year minimum to considering an 18-month sentence, while the defense pushed for a sentence involving home confinement.
