Cormac is a trial lawyer with over two decades of experience with high-stakes litigation and investigations, both as a federal prosecutor and as defense counsel. He has advised dozens of clients facing criminal and civil investigations involving all manner of federal criminal cases, federal and state False Claims Act matters, criminal antitrust allegations, and Foreign Corrupt Practices Act claims. Cormac regularly assists clients with responses to formal and informal investigative inquiries, including civil investigative demands, Grand Jury subpoenas, Office of Inspector General subpoenas and inquiries, and 28 U.S.C. § 1782 subpoenas. Whether assisting a company or an individual, Cormac appreciates the intense pressure that comes with any law enforcement investigation, helping his clients navigate the legal, financial, and reputational impacts that often follow.
Cormac has advised federal contractors facing fraud and other types of investigations, and he regularly handles False Claims Act allegations on both the federal and state levels, as well as trade enforcement investigations regarding export controls and tariff requirements. Cormac also has managed internal investigations on behalf of clients related to concerns about regulatory, statutory, or policy
compliance by management and employees. When advising clients, Cormac turns investigatory data into cogent, actionable advice, routinely presenting findings and assessments of potential areas of risk or legal exposure to management. He advises boards of directors and senior management regarding internal investigation findings, recommended corrective actions, and interactions with U.S. law enforcement authorities.
Cormac also routinely interacts with government agencies, state attorneys general and their offices, and government investigators on behalf of clients. He knows how stressful these interactions can be, and he provides clients with end-to-end representation, guiding clients during interviews and conversations with government investigators, coordinating responses to subpoenas, and handling civil investigative demands and other information requests.
In 2008, Cormac left private practice to join the U.S. Attorney’s Office for the District of Columbia, where he served as an Assistant U.S. Attorney for nearly four years. As an AUSA, Cormac served as lead prosecutor in 24 criminal trials and investigated hundreds of criminal cases, managed Grand Jury investigations, and coordinated investigative activities by law enforcement personnel. He brings that perspective and insider knowledge to every representation, providing clients with strategic advice in managing risk and—ideally—avoiding prosecution through preventive compliance.
