Kevin V. DiGregory is an American former federal prosecutor specializing in national security, espionage, and terrorism cases. He served as an Assistant United States Attorney (AUSA) in the United States Attorney's Office for the Eastern District of Virginia (EDVA), which he joined in 2001, and became a prominent figure in handling complex federal prosecutions involving threats to U.S. intelligence, counterintelligence, and national security. DiGregory also served as Chief of the Terrorism and Export Crimes Section at the U.S. Department of Justice, where he led the high-profile AIPAC espionage prosecution. His work focuses on countering espionage, unauthorized disclosures of classified information, and related offenses, often collaborating with agencies like the FBI, CIA, and Department of Justice's National Security Division. His cases have included high-profile trials that highlight vulnerabilities in U.S. intelligence operations and the legal mechanisms to address them.

Prior to his role at EDVA, DiGregory served as a Judicial Law Clerk to the Honorable Thomas Penfield Jackson at the United States District Court for the District of Columbia, likely in the late 1990s following his law school graduation. He earned his J.D. from Georgetown University Law Center in 1998. Throughout his career, DiGregory has prosecuted several notable cases, including the 2015 trial of former CIA officer Jeffrey Sterling for leaking classified information to a journalist (conviction upheld on appeal), the 2012 case against former CIA officer John Kiriakou for disclosing classified details about enhanced interrogation techniques (resulting in a guilty plea), the 2018 prosecution of former CIA officer Kevin Mallory for espionage on behalf of China (convicted), and the case against ex-CIA officer Jerry Chun Shing Lee for compromising agency assets (guilty plea in 2019). These efforts underscore his expertise in navigating sensitive classified evidence in court.

DiGregory's tenure spans multiple presidential administrations, reflecting the apolitical nature of his role in federal prosecution, though his work has drawn attention from national security watchdogs and media for its implications on press freedom, whistleblower protections, and U.S.-China relations. No public controversies or allegations against DiGregory personally are documented, positioning him as a steadfast public servant in safeguarding national interests through the judicial process. His work was based in Alexandria, Virginia, where the Eastern District operates, and he has earned recognition for his meticulous approach to high-stakes litigation.
