Acting U.S. Attorney John G.E. Marck Joins Attorney General’s Advisory Committee

Acting Attorney General Todd Blanche appointed Acting U.S. Attorney John G.E. Marck to the Attorney General’s Advisory Committee on June 2, 2026.

The committee consists of a select group of U.S. Attorneys who advise the Attorney General and senior Department of Justice leadership on national law enforcement priorities. Marck, who leads one of the nation’s busiest federal districts along the U.S.-Mexico border, now participates in those deliberations.

The appointment changes the committee’s composition by adding the acting leader of the Southern District of Texas. Marck assumes the role immediately upon appointment.

The addition means the Southern District of Texas will help set DOJ policy on border security, immigration enforcement, drug trafficking, and white-collar crime. Other committee members must now incorporate priorities from a district that files thousands of criminal cases each year, many tied to fentanyl smuggling and human trafficking.

Federal agencies that coordinate with U.S. Attorneys’ offices will adjust briefings and policy proposals to account for the new member’s input. Congress and homeland security components receive guidance shaped by a committee that includes this high-volume border jurisdiction.

This marks the latest personnel move under Acting Attorney General Todd Blanche’s leadership of the Justice Department. The Attorney General’s Advisory Committee has operated for decades as the principal channel through which the 94 U.S. Attorneys influence nationwide enforcement strategy.
