Christopher H. Casey is a Chambers-ranked, first-chair trial lawyer with extensive experience at the highest levels of federal law enforcement. His practice spans antitrust and complex business litigation, white-collar criminal defense, consumer protection, and complex internal investigations, with particular depth in the healthcare, pharmaceutical, fintech and cryptocurrency industries. Drawing on his more than 15 years of government experience — including at the United States Department of Justice, the Federal Trade Commission, and the United States Attorney’s Office — Mr. Casey brings a distinctive understanding of how state and federal government authorities investigate, enforce, and resolve civil and criminal matters affecting major corporations and individuals. In most cases, Mr. Casey successfully works out resolutions for his clients. But when an advantageous settlement is not available, he draws upon his litigation and trial skills to fight for his clients.

State Attorneys General Experience

Mr. Casey has represented companies and individuals facing a wide range of enforcement actions brought by state attorneys general in a variety of areas including antitrust, consumer protection, political corruption, and environmental and safety violations. His clients in these matters have spanned the health care, pharmaceutical, energy, transportation, education, financial services, and cryptocurrency industries. He currently serves as co-leader of the firm’s State Attorneys General Group.

Senior-Level Government Experience

Mr. Casey previously served as a Deputy Associate Attorney General at the United States Department of Justice, advising the Department’s most senior officials on the formulation and execution of enforcement policy in the areas of financial fraud, antitrust, tax, and bankruptcy. He had direct oversight responsibilities involving the Antitrust Division, the Tax Division, and the United States Trustee Program. Mr. Casey was one of two deputies to the Associate Attorney General — the Department’s third-highest ranking official — who supervised the Department’s landmark cases against the world’s largest financial institutions for the packaging and sale of Residential Mortgage-Backed Securities (RMBS) following the financial crisis. Working with the President’s Financial Fraud Enforcement Task Force and the RMBS Working Group, as well as lawyers across the Civil Division and U.S. Attorney’s Offices nationwide, he helped oversee matters that produced multibillion-dollar settlements.

While at the DOJ, Mr. Casey led the Department’s development of a first-ever policy governing the selection of compliance monitors in civil corporate settlements. He also led the Department’s response to the 2016 White House Executive Order on Competition, working directly with the Antitrust Division. Mr. Casey was a member of the working group that developed the Department’s September 2015 policy statement on “Individual Accountability for Corporate Wrongdoing,” widely known as the “Yates Memorandum.” In addition, he worked closely with the leadership of the United States Trustee Program — the watchdog of the U.S. bankruptcy system — on investigations of mortgage-loan servicing violations by major financial institutions.

Antitrust and Competition Experience

Antitrust and competition law is a core pillar of Mr. Casey’s practice. Prior to his tenure at the DOJ, where he supervised the work of the Antitrust Division, Mr. Casey spent more than five years litigating antitrust merger challenges at the Federal Trade Commission in Washington, D.C., with a primary focus on the healthcare, telecommunications, energy, chemical, and food industries. This deep grounding in federal antitrust enforcement, combined with his senior-level DOJ policy work on competition matters, positions Mr. Casey to advise clients facing antitrust scrutiny from federal agencies, state attorneys general, and private litigants. He is listed in Lawdragon’s list of 500 Leading Global Antitrust & Competition Lawyers for 2025-2026.

White-Collar Defense and Internal Investigations Experience

Mr. Casey is an experienced white-collar defense attorney who regularly conducts sensitive internal investigations for corporate clients. This aspect of his practice draws directly on his years as a federal prosecutor: as an Assistant United States Attorney for the Middle District of Pennsylvania from 1999 to 2006, he prosecuted felony white-collar, narcotics, firearms, and immigration crimes. This prosecutorial background, combined with his subsequent policy-level work at Main Justice, gives him an informed perspective on every phase of a government investigation, from the initiation of an inquiry through resolution. His first-chair trial skills, honed as an AUSA, make him a formidable adversary if settlement talks fail.

Education

Mr. Casey earned his J.D. from The George Washington University Law School and his B.A. in mathematics from The College of the Holy Cross.
