Public Service

Most recently, Marshall served as the Principal Associate Deputy Attorney General of the United States. In this role, he was a member of the DOJ senior leadership team and the principal counselor to the Deputy Attorney General. Marshall worked to oversee all DOJ personnel and components, which include, among others, the 94 U.S. Attorneys’ Offices, the National Security Division, the Criminal Division, the Antitrust Division, the Department’s other litigating components and law enforcement bureaus, including the Federal Bureau of Investigation (FBI), and the Department’s Congressional and public affairs offices.

Marshall spearheaded the development and execution of non-partisan, common-sense corporate crime enforcement strategies, including expansion of national security-related enforcement, establishment of DOJ’s new whistleblower program for white collar offenses, implementation of DOJ-wide corporate self-disclosure policies, and launch of DOJ’s compensation incentives and clawbacks program. In addition, Marshall oversaw DOJ’s work to combat international drug cartels and its immigration docket, including civil litigation, regulatory advancement, criminal enforcement, and the implementation of Joint Task Force Alpha, a cross-government initiative to enhance U.S. enforcement efforts against human smuggling and trafficking.

Previously, Marshall served as the highest-ranking career official in the Criminal Division, overseeing the Department’s most significant criminal matters, highest-profile prosecutions, and most important programs, such as its Fraud Section, its Foreign Corrupt Practices Act (FCPA) program, its Health Care Fraud Strike Force, its Office of International Affairs, its Money Laundering & Asset Recovery Section, and its flagship cybercrime and public corruption units. Marshall worked to develop and implement the Department’s strategic priorities and policies, including steering its policy on corporate cooperation with DOJ investigations. He 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 Marshall’s 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 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 cases, including the FIFA corruption investigation. 

Leadership and Recognition

Marshall has received substantial recognition for his work. At DOJ, Marshall received the Department’s highest award, the Edmund J. Randolph Award, as well as the Attorney General’s Award for Excellence in Furthering the Interests of National Security, the Director’s Award for Superior Performance, and the Federal Law Enforcement Foundation’s Prosecutor of the Year Award. He was awarded the Henry L. Stimson Medal by the New York City Bar Association, recognizing the EDNY’s most outstanding AUSA in the Criminal Division, and the J. Michael Bradford Award, presented by the National Association of Former U.S. Attorneys for the most outstanding performance by an AUSA nationwide. He is also the winner of a National Intelligence Merit Award, presented by the Director of National Intelligence. Global Investigations Review also honored him with its annual award for the “Best Speech on White Collar Enforcement.”

Marshall also works to advance the law through his work with numerous legal services, bar association, and legal reform organizations. He is a past chair of New York City Bar Association’s White Collar Crime Committee and the former Treasurer, Audit & Budget Committee Chair, and member of the Board of Directors for Legal Services NYC, the nation’s largest civil legal services provider. Previously, he served on advisory boards at the Center for Justice Innovation, which seeks to create a more effective and humane justice system, and the NYU Program on Corporate Compliance & Enforcement, which works to advance understanding of the causes of corporate misconduct and the nature of effective enforcement and compliance.
