Mark Filip

On August 28, 2008, Deputy Attorney General Filip issued a binding revision to the "Principles of Federal Prosecution of Business Organizations," replacing the McNulty Memorandum. The Filip Memo introduced several consequential changes: cooperation credit no longer required waiver of attorney-client privilege, instead focusing on "disclosure of relevant facts"; it explicitly codified DPAs and NPAs as a legitimate third option between indictment and declination; it prohibited government requests for non-factual privileged materials; and it established the "Filip Factors" for evaluating corporate cooperation. The memo was drafted with chief of staff Brian Benczkowski, who would later oversee DPA enforcement as AAG Criminal Division (2018–2020).

The operational significance of this document became clear only after Filip left government. Returning to Kirkland & Ellis in May 2009, Filip deployed the framework he had authored to defend the three largest corporate criminal cases of the 2010s–2020s. BP Deepwater Horizon (2012): 14 felony counts including 11 manslaughter charges, $4.525 billion criminal settlement — then the largest in U.S. history. Volkswagen Dieselgate (2017): guilty plea with $4.3 billion penalty and an independent compliance monitor, co-counseled with Benczkowski at K&E. Boeing 737 MAX (2021): a DPA with $2.5 billion total but only $243.6 million in criminal penalties, no guilty plea, no executive charged, and no compliance monitor — despite 346 deaths from fraud on the FAA. The Boeing DPA was later found breached by DOJ in 2024 and ultimately resolved through a non-prosecution agreement in May 2025. Filip's additional defense portfolio at K&E includes Goldman Sachs (1MDB), General Motors (ignition switch), JP Morgan Chase (market manipulation/spoofing), Allergan (opioid MDL), and Abbott Laboratories (misbranding, with Benczkowski).

The comparison between VW and Boeing is particularly revealing. Same defense firm, same lead counsel (Filip), same co-counsel (Benczkowski on VW, returned to DOJ for the Boeing era). VW: guilty plea, independent monitor, $4.3 billion. Boeing: DPA, no monitor, no guilty plea, $243.6 million criminal fine — despite causing 346 deaths compared to zero for VW's emissions fraud. The critical variable that changed between 2017 and 2021 was not the severity of the conduct but the composition of DOJ leadership: by 2021, AG William Barr (K&E Of Counsel), DAG Jeffrey Rosen (29-year K&E partner), and AAG Benczkowski (K&E partner) had all recently occupied or still held the DOJ positions overseeing Boeing's case. Harvard Law analysis called the Boeing DPA "one of the worst deferred prosecution agreements," noting that judge and venue were chosen to favor Boeing despite the company having no Texas connection.

Filip's connection to the Epstein matter is institutional rather than personal, but it occupies a critical position in the chain of authority. The Epstein NPA was signed on September 24, 2007, before Filip's confirmation as Deputy Attorney General. Filip assumed the DAG role on March 10, 2008, at which point the NPA was in its execution phase. Epstein pled guilty under the state component of the arrangement on June 30, 2008, while Filip held the second-highest position at DOJ.

Deposition transcript EFTA00009329 confirms that defense counsel made "a small appeal to the DAG's office" — Filip's office — "and submitted a fairly substantial accounting" of the case. A separate defense document ¹, sent by Epstein to Kathy Ruemmler on December 9, 2018, claimed the NPA was "reviewed by three levels of senior officials at the Department of Justice in Washington: first by the heads of CEOS (Child Exploitation and Obscenity Section), then by the Criminal Division, and finally by the Deputy Attorney General, Mark Filip, who, with the exception of the Attorney General himself, was the highest ranking official at the Department." While this characterization appeared in an Epstein defense document and thus served Epstein's interest in legitimizing the NPA, the deposition evidence corroborates that Filip's office was indeed involved in review.

The structural irony is considerable. K&E partner Ken Starr wrote directly to DAG Filip's office lobbying to drop the federal case against Epstein ². Filip's chief of staff Benczkowski had previously authored a November 9, 2007 DOJ letter cited by K&E in the Epstein defense, arguing that prostitution crimes belonged at the state level. The chain runs: K&E partner (Starr) writes to K&E alumnus (Filip, as DAG), whose chief of staff (Benczkowski) later joins K&E (2010), then becomes AAG Criminal Division (2018) overseeing the exact statutes (18 USC 1591) used to prosecute Epstein in 2019. Filip himself, after reviewing the NPA from the government side, returned to K&E and became the firm's most prominent corporate criminal defense partner — defending clients using the same DPA/NPA machinery that had been extended to Epstein.

The Filip-Benczkowski relationship is the defining mentor-protege pairing in modern DOJ-to-private practice history. Benczkowski served as Filip's chief of staff in the Office of the Deputy Attorney General (2008), where together they co-authored the Filip Memorandum establishing the DPA framework. When Filip returned to Kirkland & Ellis in May 2009, Benczkowski followed in 2010, and they served as co-counsel on at least three major corporate criminal cases: BP Deepwater Horizon, Volkswagen Dieselgate, and Abbott Laboratories misbranding.

In 2018, Benczkowski returned to DOJ as Assistant Attorney General for the Criminal Division — the division that directly oversees DPAs — while Filip continued defending Boeing and Goldman Sachs at K&E. The conflict was manifest: Benczkowski received an ethics waiver in April 2019 to participate in the Goldman Sachs 1MDB case despite K&E (via Filip) representing Goldman. A second waiver followed in November 2018 for 1MDB, and a third in December 2019 for an unspecified "confidential criminal matter." AG Barr received parallel 1MDB waivers. Goldman ultimately paid $2.9 billion but escaped a guilty plea — a favorable outcome given that $6.5 billion was allegedly misappropriated and Goldman earned $600 million in fees. Filip's former K&E colleagues simultaneously wrote the enforcement rules (Filip Memo), staffed the enforcers (Barr, Benczkowski, Rosen), and defended the targets (Filip at K&E).

Benczkowski returned to K&E in September 2020. In September 2025, he joined Boeing as VP/Assistant General Counsel for Government Operations — the same company Filip had defended against criminal prosecution, and whose DPA Benczkowski's Criminal Division had overseen. The revolving door did not merely rotate between government and one firm; it concentrated the architect of the DPA system, the co-author who enforced it, and the corporate client who benefited from it into a single institutional orbit.

Filip's career at K&E reveals a figure who operates on both sides of the corporate criminal enforcement divide, sometimes simultaneously. In January 2017, Judge Thelton E. Henderson appointed Filip as Compliance and Ethics Monitor of PG&E following the utility's five felony convictions for willful violations of the Natural Gas Pipeline Safety Act and corrupt obstruction of the investigation into the 2010 San Bruno gas explosion, which killed eight people. Filip served as monitor for five years until PG&E's probation ended in January 2022. During his tenure, he raised alarms about wildfire prevention, writing: "We doubt anyone would seriously contend PG&E's performance has been adequate, or that substantial improvement is not still imperative."

This role — appointed by the same DOJ he previously ran — demonstrates the bidirectional nature of Filip's government ties. He defends corporations against DOJ prosecution AND monitors corporations for DOJ compliance, depending on the engagement. In February 2020, DOJ proposed Filip as Live Nation/Ticketmaster compliance monitor while he was actively defending Boeing against DOJ prosecution. The fact that DOJ considered the same attorney trustworthy enough to serve as its monitor while he was defending a client against DOJ prosecution underscores the degree to which Filip's institutional position transcends the adversarial structure of the legal system. He does not merely pass through the revolving door; he operates as though the door is permanently open.

Erin Nealy Cox, the U.S. Attorney for the Northern District of Texas who oversaw Boeing's prosecution and signed the DPA on January 7, 2021 — her last day in office — joined K&E as a partner in June 2021. Filip personally welcomed her per the firm's press release. She now practices government regulatory and internal investigations at K&E in Dallas, the same city where the Boeing case was filed. Columbia Law Professor John Coffee observed: "the US Attorney's joining the defense counsel's law firm suggests they were both on the same wavelength."

Filip's political donations are exclusively Republican according to LittleSis entity 128114: George W. Bush (1999–2003), RNC (2012), NRSC (2002), NRCC (2002), Illinois Republican Party (2000–2002), 2002 Presidents Dinner Committee, Mitt Romney (2011–2012), Mark Kirk (R-IL, 2009–2011), Robert Dold (R-IL, 2010–2012), George Allen (R-VA, 2011), Freedom First PAC (2009), and Skadden PAC (2003). No Democratic donations have been identified. Notably, no FEC records appear under a Kirkland & Ellis employer listing, despite Filip's partnership since 2009.

His educational pedigree — UIUC summa cum laude, Oxford First Class as a Marshall Scholar, Harvard Law magna cum laude with Law Review — combined with the Scalia clerkship and a 96-0 Senate confirmation for his judgeship, positions Filip within the elite stratum of the conservative legal establishment. His career arc traces the Federalist Society pipeline from judicial clerk to federal bench to executive branch to BigLaw partnership. Yet Filip's influence operates primarily through institutional position rather than political visibility. He does not appear in political commentary or media profiles with the frequency of a Barr or a Clayton. His power is exercised through the K&E Executive Committee, where he helps shape firm strategy; through the DPA framework he authored, which structures every major corporate criminal negotiation; and through the relationships with former subordinates and colleagues who cycle between K&E and DOJ leadership.
