“Edward O’Callaghan has served the Department of Justice with distinction, excelling as a prosecutor in the Southern District of New York and most recently as the Principal Deputy Assistant Attorney General in the National Security Division. His experiences in a variety of roles throughout the Department will be invaluable as we work to protect our national security, reduce violent crime, and promote the rule of law,” said Deputy Attorney General Rosenstein. “I also want to thank Robert Hur for serving as the Principal Associate Deputy Attorney General. His counsel was invaluable over the past ten months and I look forward to seeing him thrive as the United States Attorney for the District of Maryland.”
Prior to his appointment as Acting Principal Associate Deputy Attorney General, O’Callaghan most recently served as Principal Deputy Assistant Attorney General for the National Security Division, where he assisted the Assistant Attorney General in the administration of all units and components in the National Security Division, most notably in the Counterterrorism Section, the Counterintelligence and Export Control Section, the Office of Intelligence, the Office of Law & Policy, the Foreign Investment Review Staff, and the Office of Justice for the Victims of Overseas Terrorism. While awaiting the confirmation of Assistant Attorney General John Demers, O’Callaghan served as Acting Assistant Attorney General for the National Security Division.
Before rejoining the Department of Justice in 2017, O’Callaghan was a partner at an international law firm. O’Callaghan specialized in defending financial institutions, public companies, asset management firms, and individuals in international and domestic regulatory investigations and criminal prosecutions. These cases involved securities fraud, bank fraud, money laundering, RICO, and corruption, among other things.
O’Callaghan previously served as an Assistant U.S. Attorney for the Southern District of New York from 1999 to 2008. He was also Co-Chief of the Terrorism & National Security Unit from 2005 to 2008. As an Assistant U.S. Attorney, O’Callaghan was the lead prosecutor on several important cases, including the Department of Justice’s international fraud investigation and prosecutions in relation to corruption in the United Nations Oil-for-Food Program, RICO prosecutions of crime families, and numerous bank and securities fraud cases. He received the U.S. Attorney General's Award for Distinguished Service in 2008, and the Director's Award for Superior Performance as an Assistant U.S. Attorney in 2000.
After earning his J.D. from NYU Law School in 1994, O’Callaghan began his career as a clerk to the Honorable Kevin Thomas Duffy of the U.S. District Court for the Southern District of New York.
