Erin Nealy Cox, the former United States Attorney for the Northern District of Texas, is a trial lawyer who represents corporations, boards of directors, and executives involved in complex multi-jurisdictional disputes and high-stakes investigations. As a partner in the Firm’s Dallas and Washington, D.C., offices, she is a member of the Firm’s Government, Regulatory & Internal Investigations Practice Group.
Erin has a broad practice focused on matters arising from alleged violations of state and federal laws, including fraud, cybersecurity, public corruption, national security, workplace compliance, and issues involving board governance. She has successfully tried numerous cases in federal courts throughout her two and a half decades in public service and private practice.
Erin has deep experience in government service having served at the highest levels of the Department of Justice as United States Attorney, and before that as an Assistant United States Attorney. As the United States Attorney for the Northern District of Texas, Erin led an office of 250 employees responsible for prosecuting wide-ranging and complex federal cases, including financial, securities, health care, government contracting and program fraud, as well as Foreign Corrupt Practices Act (FCPA), money laundering, public corruption, computer crime, and opioid-related matters. She successfully quarterbacked the Northern District of Texas’ most significant investigations, and during her tenure, the office prosecuted more cases and more defendants than any other non-border district in the nation. As U.S. Attorney, she was recognized nationally for her work in developing strategic responses to benefit the eight million residents of the North District of Texas. She was also recognized nationally and locally for her efforts to combat domestic violence through gun control initiatives and her work to eradicate human trafficking through the efforts of the North Texas Trafficking Task Force.
While serving as U.S. Attorney, she also served as Chairperson of the Attorney General’s Advisory Committee (AGAC), a body of 15 U.S. Attorneys selected by the Attorney General to advise on national priorities, including policy and operational issues. Erin also led the AGAC task force on domestic violence and firearms crimes.
Prior to her appointment as U.S. Attorney in 2017, she served briefly as a senior advisor at McKinsey & Co., in the consulting firm’s cybersecurity and risk practice. Before that, Erin was executive managing director at Stroz Friedberg, a cybersecurity and investigations consulting firm, ultimately leading the firm’s global incident response business. During her prosecutorial career, Erin served as Chief of Staff and Senior Counsel to the Assistant Attorney General in the DOJ’s Office of Legal Policy in Washington, D.C. She also served as an Assistant U.S. Attorney in the Northern District of Texas, where she prosecuted white collar, cyber, and violent crimes for almost a decade.
