HOUSTON - Acting Attorney General Todd Blanche recently appointed Acting U.S. Attorney John G.E. Marck to serve on a select and prestigious body of U.S. Attorneys that advises Department of Justice leadership on national law enforcement priorities.
Marck's appointment to the Attorney General's Advisory Committee of U.S. Attorneys reflects both his leadership in one of the largest districts in the nation and the important role the Southern District of Texas plays in confronting emerging threats to public safety and national security.
The AGAC was created in 1973 and is designed to ensure broad geographic, operational and subject-matter representation and elevates the voices of U.S. Attorneys on matters of policy, procedure and management impacting offices throughout the nation.
Members work through subcommittees and working groups on issues including violent crime, national security, fraud, narcoterrorism and other critical priorities. The AGAC plays a central role in ensuring that the experience of federal prosecutors in the field informs on national Department of Justice strategy.
"It is an immense honor to be appointed to the AGAC, and I am deeply grateful to Acting Attorney General Blanche for his confidence and trust in me," said Marck. "The Southern District of Texas is home to some of the most dedicated federal, state and local law enforcement officers in the country, and I am proud to carry their work and their mission into this important forum."
Marck and other AGAC members met with Blanche and other DOJ leadership in May and will hold the first substantive meeting later this month.
Marck will serve alongside U.S. Attorney Dan Bishop (Middle District of North Carolina), U.S. Attorney Andrew Boutros (Northern District of Illinois), U.S. Attorney Scott Bradford (District of Oregon), Acting U.S. Attorney Catherine Crosby (Northern District of Alabama), U.S. Attorney Timothy Courchaine (District of Arizona), U.S. Attorney Michael Dunavant (Western District of Tennessee), First Assistant U.S. Attorney Ryan Ellison (District of New Mexico), First Assistant U.S. Attorney Bilal Essayli (Central District of California), U.S. Attorney Adam Gordon (Southern District of California), U.S. Attorney Jerome Gorgon (Eastern District of Michigan), U.S. Attorney Peter McNeilly (District of Colorado), U.S. Attorney David Metcalf (Eastern District of Pennsylvania), U.S. Attorney Jeanine Pirro (District of Columbia), U.S. Attorney Jason Reding Quiñones (Southern District of Florida) and U.S. Attorney Lesley Woods (District of Nebraska).
As Acting U.S. Attorney, Marck is the chief federal law enforcement officer in the Southern District of Texas, responsible for prosecuting and defending the interests of the United States in one of the largest and busiest districts in the nation.
Before being appointed Acting U.S. Attorney, Marck served as First Assistant U.S. Attorney, overseeing the Criminal, Civil and Appellate Divisions. Prior to that, he was in the National Security and Public Corruption Section where he served as Associate Deputy Criminal Chief, supervising a team of Assistant U.S. Attorneys, intelligence officers and support staff in prosecuting complex national security, counterintelligence and cybercrime cases.
Marck began his federal career as an AUSA in the Corpus Christi and Victoria Divisions of the Southern District of Texas, where he managed a diverse criminal docket that included charges of illegal reentry, alien smuggling, drug trafficking and other cartel-related offenses.
Prior to joining the SDTX, Marck was an Assistant District Attorney in New York City, serving in both the Brooklyn and Bronx District Attorney's offices. As an ADA, Marck prosecuted a high-volume caseload of major felonies, including murder, manslaughter, robbery and gang assault.
The U.S. Attorney's Office for the Southern District of Texas remains one of the busiest in the nation. It represents 43 counties, more than 10 million people, covers 44,000 square miles and comprises seven U.S. District Court divisions. Headquartered in Houston, SDTX has branch offices in Galveston, Victoria, Corpus Christi, Brownsville, McAllen and Laredo.
