-Who's Who Legal
At the Department of Justice, Marshall served as the highest-ranking career official in the Criminal Division, overseeing the Department’s most significant criminal matters and highest-profile prosecutions. Marshall supervised over 600 federal prosecutors, as well as the Department’s most important programs and prosecutions, such as its Foreign Corrupt Practices Act program, its Health Care Fraud Strike Force, its Office of International Affairs, and its flagship cybercrime and public corruption units. Marshall worked to develop and implement the Department’s strategic priorities and policies, including updating and steering its policy on corporate cooperation with DOJ investigations. Marshall testified on Capitol Hill and provided briefings and counsel to Congressional staff and executive branch officials, with an emphasis on cybersecurity, asset forfeiture, and anti-corruption measures. Following his departure from the DOJ, Attorney General Loretta E. Lynch lauded Marshall as “an outstanding attorney, a remarkable public servant, and an unwavering advocate for the principles of justice.”
Marshall began his career in public service at the U.S. Attorney’s Office for the Eastern District of New York (“EDNY”), serving as an Assistant United States Attorney for over a dozen years. At the EDNY, Marshall served in a number of leadership roles, including National Security Coordinator, Chief of the Violent Crimes & Terrorism Section, and ultimately Chief of the Office’s Criminal Division. As the EDNY Criminal Chief, Marshall oversaw all of the Office’s criminal prosecutions, including many of the nation’s most significant corruption, cybercrime, corporate fraud, sanctions violations, and international terrorism cases.
"An outstanding attorney, a remarkable public servant, and an unwavering advocate for the principles of justice.”
