Erin Nealy Cox
Former federal cybercrime prosecutor, Trump-appointed US Attorney for the Northern District of Texas (2017–2021), and current Kirkland & Ellis partner specializing in government regulatory and internal investigations.
Erin Nealy Cox served as US Attorney for the Northern District of Texas from November 2017 through January 9, 2021 — a Trump appointee whose career spans federal cybercrime prosecution, cybersecurity consulting at Stroz Friedberg (2008–2016), and a senior advisor role at McKinsey 1. On January 7, 2021 — two days before her resignation took effect — her office filed case 4:21-cr-00005 (NDTX): a deferred prosecution agreement with The Boeing Company over the 737 MAX MCAS fraud and the deaths of 346 people 2. The DPA imposed $2.51 billion in financial obligations but required no guilty plea, no executive prosecution, and no independent compliance monitor; the case was filed in NDTX despite Boeing having no Texas corporate presence, a venue choice Columbia Law professor John Coffee publicly characterized as suspicious 2.
According to the K&E press release, five months later Kirkland & Ellis announced Nealy Cox as a partner in its Dallas office, with the announcement authored by Mark Filip, the K&E partner who had signed the Boeing DPA as lead defense counsel 3. Analysis of the timeline and public statements indicates that the prosecutor and her principal adversary became law firm colleagues within a single calendar year 3. The DPA was later found breached after the January 2024 Alaska Airlines door-plug blowout, and the full case cycle — DPA filed January 2021, breach May 2024, replacement NPA May 2025, dismissal November 2025 — concluded without a criminal conviction 4. According to media analysis, victims’ advocate attorney Paul Cassell and the American Prospect drew a structural parallel to the 2008 Jeffrey Epstein non-prosecution agreement, in which according to commentators another Trump-appointed US Attorney had negotiated an agreement widely criticized as lenient with K&E on the defense side 5.
Career Background
Nealy Cox was born in 1970 in Pascagoula, Mississippi. She earned a BBA from the University of Texas at Austin and a JD magna cum laude from SMU Dedman School of Law, then clerked for Judge Henry Politz on the Fifth Circuit and Judge Barefoot Sanders in NDTX 1. She joined Simpson Thacher briefly (1996–97) before entering the NDTX US Attorney’s office as an AUSA in 1999, where she handled cybercrime and white-collar matters through 2008 — including a detachment to DOJ Main Justice in 2004–05 as chief of staff to the Assistant Attorney General for the Office of Legal Policy 1. She spent 2008–2016 at Stroz Friedberg, a digital forensics and cybersecurity consultancy, as an executive 1. A one-year stint as a senior advisor at McKinsey preceded her nomination as US Attorney for NDTX on September 22, 2017; she was confirmed November 9 and sworn in November 17 of that year 1. She is a Federalist Society contributor and serves on the board of Sally Beauty Holdings 1.
The Boeing 737 MAX Deferred Prosecution Agreement
Case 4:21-cr-00005, filed in NDTX on January 7, 2021, charged The Boeing Company with one count of conspiracy to defraud the United States in connection with the fraudulent representations made to the FAA regarding the 737 MAX MCAS flight control system — the system implicated in the Lion Air Flight 610 crash (October 2018, 189 deaths) and the Ethiopian Airlines Flight 302 crash (March 2019, 157 deaths), 346 total deaths 2. The DPA was assigned to Judge Reed O’Connor in NDTX 2. The financial terms totaled $2.51 billion: $243.6 million criminal penalty, $500 million victim compensation fund, and $1.77 billion in airline customer compensation 2. No individual Boeing executive was charged, Boeing entered no guilty plea, and no independent compliance monitor was required — provisions that legal commentators characterized as atypical for an agreement of this magnitude 2. The case was brought in NDTX despite Boeing’s lack of Texas corporate presence; Professor Coffee publicly questioned the venue selection 2.
The DOJ case record (EFTA00040903 and related Morning Digests in the DugganUSA corpus) documents Nealy Cox’s active role as NDTX US Attorney during the preceding period, including a July 30, 2020 tax fraud prosecution attributed to her office 6. The CourtListener docket (29089563) lists Chad Meacham as the lead line prosecutor, with Mark Filip of Kirkland & Ellis signing for Boeing on the defense side; former NDTX US Attorney Richard Roper III also appeared 6. Nealy Cox’s resignation took effect on January 9, 2021 — two days after the DPA was filed 2.
The DPA was found breached on May 14, 2024 — DOJ determined Boeing had failed to implement the required compliance program under paragraphs 21, 22, and 26(d) 4. The breach was triggered in part by the January 5, 2024 Alaska Airlines door-plug blowout 4. A proposed plea deal was rejected by Judge O’Connor on December 5, 2024 over objections to the monitor-selection process 4. A replacement non-prosecution agreement was reached on May 23, 2025: $444.5 million victim fund and $240 million criminal fine, with Boeing hiring its own outside contractor rather than a court-appointed monitor 4. Judge O’Connor dismissed the case on November 6, 2025; victims’ families filed Fifth Circuit mandamus petitions on November 13, 2025 4. The complete cycle — DPA January 2021 through NPA dismissal November 2025 — concluded without a criminal conviction 4.
Transition to Kirkland & Ellis
According to records, on June 23, 2021 — five months after the Boeing DPA was filed — Kirkland & Ellis announced Nealy Cox as a new partner in its Dallas office 3. According to the K&E announcement, it was authored by Mark Filip, who had led the Boeing defense and signed the DPA on Boeing’s behalf, and by Andrew Calder, a K&E Houston partner and executive committee member who cited his "personal experience" with her 3. According to the announcement, Nealy Cox began at K&E on September 1, 2021, practicing in government regulatory and internal investigations 3. According to Corporate Crime Reporter, the outlet headlined its coverage: "Lead Boeing Prosecutor Joins Boeing Corporate Criminal Defense Firm Kirkland Ellis" 3.
According to legal press coverage, Professor Coffee characterized the US Attorney’s move to the defense counsel’s firm as suggesting "they were both on the same wavelength" 3. According to court records, Boeing victims’ families filed claims of impropriety, which were withdrawn on January 20, 2022 3. Records show the documented sequence: DPA filed January 7, 2021; resignation effective January 9, 2021; K&E announcement June 23, 2021; K&E start date September 1, 2021 23.
Examination of the broader K&E–DOJ revolving door places Nealy Cox’s transition in a documented pattern: Mark Filip authored the "Filip Factors" as Deputy AG (2008–09) before returning to K&E and deploying those same criteria on behalf of Boeing, BP, Volkswagen, and Goldman Sachs; K&E partner Brian Benczkowski moved in the opposite direction — K&E to head of DOJ Criminal Division — and then to Boeing as VP/Assistant General Counsel in September 2025 3.
Structural Parallel: Acosta and the Epstein NPA
According to public statements, attorney Paul Cassell — victims’ advocate in both the Epstein and Boeing cases — publicly drew the comparison between the two agreements 5. Analysis of the two cases identifies the following structural parallels: both involved Trump-appointed US Attorneys who negotiated agreements that legal commentators characterized as historically lenient for the magnitude of the conduct; both had Kirkland & Ellis on the defense side — K&E partners Jay Lefkowitz and Ken Starr negotiated Alexander Acosta’s 2008 Epstein non-prosecution agreement, while K&E partner Mark Filip signed the 2021 Boeing DPA; and both US Attorneys resigned shortly after their respective agreements 5. According to the public record, Acosta became Labor Secretary and resigned in July 2019 when the Epstein NPA received renewed scrutiny; Nealy Cox resigned January 9, 2021 and joined K&E 5. According to the American Prospect, the outlet titled its February 9, 2024 analysis "The Boeing Epstein Deal" 5.
Records show one documented difference: Acosta was himself a former K&E associate prior to his government service, while Nealy Cox had no prior K&E affiliation before the Boeing matter 5. Analysis of the structural features of the two agreements and documented public statements by Cassell and media commentators supports this parallel as a synthesis-level inference; it does not rest on any documented communication between the two matters or the two US Attorneys 5.
Political Contributions
FEC Schedule A filings show Nealy Cox — listing her address as 3432 Southwestern Blvd, Dallas TX 75225 and her employer as Kirkland Ellis — made the following federal contributions while a K&E partner: $8,300 to the Vance Victory joint fundraising committee (split between JD Vance for Senate and Working for Ohio PAC) on April 5, 2024 (FEC committees C00817072 and C00783142); $1,000 to Never Surrender Inc, a Trump leadership PAC, on October 31, 2024 (committee C00828541); $2,900 to Christina Nolan for U.S. Senate (VT-R) on April 27, 2022, and $1,000 on January 29, 2022 (committee C00800532) 7. The Nolan donation is documented against the context that Nolan was herself a Trump-appointed U.S. Attorney (District of Vermont) 7. All recorded donations are to Republican candidates and committees 7.

DugganUSA corpus shows Nealy Cox active as NDTX USA in DOJ Morning Digests (EFTA00040903 et al). Jul 30 2020 digest attributes NDTX tax fraud prosecution announcement to Nealy Cox. The DOJ corpus contains 1000 hits for Nealy Cox across the Epstein document releases - all are DOJ administrative news digests from her tenure as USA, not Epstein-related content. No direct Epstein connection found in any document corpus. The Boeing case CourtListener docket (29089563) confirms case filed Jan 7 2021 with Chad Meacham (DOJ) as lead prosecutor alongside Filip (K&E defense). Richard Roper III also appeared - he was the prior NDTX USA.
Boeing DPA precise details: Case 4:21-cr-00005 NDTX filed Jan 7 2021, assigned Judge Reed O Connor. Boeing charged with one count of conspiracy to defraud the US (fraud on FAA re MCAS system). DPA terms: $243.6M criminal penalty, $500M victim fund, $1.77B airline customer compensation = $2.51B total. No executive charged. No guilty plea. No compliance monitor required (unusual). DPA held charge in abeyance for 3 years. Key negotiators: Mark Filip (K&E, defense) signed for Boeing. Case brought in NDTX despite Boeing having no Texas connection - Prof Coffee called venue choice suspicious.
Boeing DPA breach and final resolution: May 14 2024 DOJ determined Boeing breached DPA paras 21/22/26d - failed to implement compliance program. Triggered by Jan 5 2024 Alaska Airlines door plug blowout. DOJ proposed plea deal rejected by Judge O Connor Dec 5 2024 (objected to monitor selection process). May 23 2025 DOJ and Boeing reached non-prosecution agreement: $444.5M victim fund + $240M criminal fine = $1.1B+. Boeing admits conspiracy to obstruct FAA. No court-appointed monitor - Boeing hires own outside contractor. Nov 6 2025 Judge O Connor dismissed the case. Families filed 5th Circuit mandamus petitions Nov 13 2025. The full cycle: DPA Jan 2021, breach May 2024, NPA May 2025, dismissal Nov 2025 - no criminal conviction after 346 deaths.

K&E recruitment and Boeing overlap analysis: K&E press release Jun 23 2021 shows Mark Filip personally welcomed Nealy Cox. Filip led Boeing defense team AND signed the DPA. Andrew Calder (K&E Houston partner, exec committee) also welcomed her citing our personal experience with her. The K&E announcement was made 5 months after Boeing DPA. Cox started Sep 1 2021 in Dallas - the same city where the Boeing case was filed. Prof Coffee: the US Attorneys joining the defense counsels law firm suggests they were both on the same wavelength. Victims families initially alleged impropriety but withdrew claims Jan 20 2022. Cox now practices government regulatory and internal investigations - the exact work that defends against the type of prosecution she previously conducted.
Acosta-Nealy Cox structural parallel: Both were Trump-appointed US Attorneys. Both negotiated historically lenient agreements for wealthy/powerful defendants (Acosta: Epstein NPA 2008, Nealy Cox: Boeing DPA 2021). Both agreements criticized as among worst of their kind. Both had K&E on the defense side (Acosta: Lefkowitz/Starr from K&E, Nealy Cox: Filip from K&E). Both resigned shortly after the agreements. Acosta became Labor Secretary then resigned over Epstein scrutiny. Nealy Cox joined K&E directly. Key difference: Acosta was a former K&E associate himself, while Nealy Cox had no prior K&E connection. Same lawyer Paul Cassell represented victims in both cases and drew the explicit comparison. American Prospect titled its article Boeing Epstein Deal.
