J. Philip Ludvigson

J. Philip Ludvigson advises clients on national security risks related to foreign direct investment. Phil has held senior roles within the U.S. Departments of Treasury and Homeland Security and draws upon his extensive experience to guide clients in resolving a variety of matters, including those related to the Committee on Foreign Investment in the United States (CFIUS), the Outbound Investment Security Program (OISP), and Information and Communications Technology and Services (ICTS).

Prior to joining King & Spalding, Phil was the Acting Deputy Assistant Secretary for Investment Security at the U.S. Department of the Treasury. He also served as the Director for Monitoring & Enforcement—the first person in Treasury’s history ever to hold that role—and built the office that pursues CFIUS non-notified transactions and oversees all CFIUS mitigation measures, including compliance monitoring and enforcement actions. Phil also coordinated Treasury’s advisory role in the Committee for the Assessment of Foreign Participation in the United States Telecommunications Services Sector, otherwise known as “Team Telecom.” Before joining Treasury, Phil held various roles at the Department of Homeland Security (DHS), including serving as the Acting Director of Foreign Investment Risk Management, where he led all aspects of the agency’s participation in CFIUS and Team Telecom, and as Senior Counsel at the Transportation Security Administration (TSA). He also practiced law for several years in the Washington, D.C. office of an AmLaw 10 firm, focusing on government contracts, security clearances, and Foreign Ownership, Control, or Influence issues. Phil is also a retired Army Reserve officer and combat veteran and was the Production Editor of the University of Illinois Journal of Law, Technology & Policy in law school.

Having overseen the entire lifecycle of U.S. national security reviews of in-bound investment for both CFIUS and Team Telecom matters, Phil now focuses his practice on providing strategic advice for clients seeking to identify and address potential jurisdiction and risk-related concerns as they structure investments and other business transactions, as well as guiding them through the filing process and mitigation compliance. He also advises clients in a variety of other emerging national security regulatory areas, including supply chain initiatives, transportation and critical infrastructure, and government contracts.
