Erin Nealy Cox

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.

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.

DOJ Morning Digests in the released records (EFTA00040903 and related) document 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.

Review of the records shows that 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, in a release 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. Examination of the announcement and contemporaneous coverage shows that Nealy Cox began at K&E on September 1, 2021, practicing in government regulatory and internal investigations, and that Corporate Crime Reporter headlined its report "Lead Boeing Prosecutor Joins Boeing Corporate Criminal Defense Firm Kirkland Ellis"; Columbia Law professor John Coffee described the US Attorney’s move to the defense counsel’s firm as suggesting "they were both on the same wavelength" ³.

Court records show that Boeing victims’ families filed claims of impropriety, which were withdrawn on January 20, 2022, and that the documented sequence runs: 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.

According to attorney Paul Cassell — victims’ advocate in both the Epstein and Boeing cases — the two agreements invite direct comparison, one he drew publicly ⁵. Cross-reference of the two cases shows several 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. Review of the public record shows that Acosta became Labor Secretary and resigned in July 2019 when the Epstein NPA received renewed scrutiny, that Nealy Cox resigned January 9, 2021 and joined K&E, and that the American Prospect titled its February 9, 2024 piece "The Boeing Epstein Deal" ⁵.

Cross-reference of the careers identifies 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 rests on those parallels and on the public statements of Cassell and media commentators; it is an analytical comparison and does not rest on any documented communication between the two matters or the two US Attorneys ⁵.

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.
