Joseph Charles Folio III

Of Counsel | Washington, D.C. | (202) 887-1578
(202) 887-1578

Before joining the firm, Joe most recently served as Chief Counsel for the U.S. Senate Committee on Homeland Security & Governmental Affairs, where he advised on all issues falling within the committee’s broad jurisdiction, including cybersecurity, border security, domestic terrorism, election security, supply chain security (including 5G policy), and reforming the National Emergencies Act. As part of the committee’s cybersecurity work, Joe advised on oversight of the newly established Cybersecurity and Infrastructure Security Agency (CISA) within the Department of Homeland Security, legislation providing CISA with administrative subpoena authority, the recent creation of the National Cyber Director, and oversight of government and private efforts to protect against and respond to cyber breaches and ransomware attacks.

Prior to his work on the hill, Joe was a DOJ trial attorney for over a decade. As a prosecutor in the DOJ’s Antitrust Division, he investigated and prosecuted domestic and international cartels, obtained several plea agreements, and, in an international freight-forwarding investigation, successfully argued for the pre-trial detention of an executive who posed a risk of flight. As chief of staff for the generic pharmaceuticals investigation, he oversaw all aspects of the case, including the handling of parallel civil proceedings and the consolidated multidistrict litigation case.

Joe also spent seven years as a trial attorney in the DOJ’s Civil Division, Federal Programs Branch, where he focused on national security matters. He was lead attorney in multiple Guantanamo habeas proceedings, Terrorism Watch List cases, cases involving assertions of the state secrets privilege, Freedom of Information Act (FOIA) litigation, and related national security matters. Outside of the national security context, he served as co‑counsel defending the Export-Import Bank against multiple administrative and constitutional challenges. For many of these matters, he represented the division at intra- and inter-agency meetings, including National Security Staff meetings.

Now in private practice, Joe leverages his experience across all three branches of government, including criminal and civil litigation, to aid clients through complex matters in both the antitrust and national security areas. His breadth of experience offers unmatched insider knowledge across a variety of enforcement perspectives for clients in the financial services, technology, healthcare, defense, and communications sectors.   

Joe received his B.A. in philosophy and government and M.A. in securities studies from Georgetown University, and he also received his J.D. from the George Mason University School of Law. After graduating from law school, Joe clerked for the Honorable Richard L. Voorhees on the U.S. District Court for the Western District of North Carolina.
