Antitrust: Cartel

Career

James (“Jimmy”) Attridge – former Chief of Staff of the U.S. Department of Justice (DOJ) Antitrust Division, Counsel to the Assistant Attorney General, and federal prosecutor – represents clients in cartel investigations, antitrust litigation, and complex merger reviews. Drawing on his government experience under multiple administrations, Jimmy provides a strategic and comprehensive perspective on a wide range of government investigations and litigation.

Lauded by clients in The Legal 500 United States for his work representing both companies and individuals in cartel matters, Jimmy is adept at navigating antitrust compliance issues, cartel investigations and defense, and follow-on civil litigation. He also counsels clients on engaging with the DOJ in a range of areas where the Antitrust Division has committed to heightened enforcement, including merger reviews, civil conduct investigations, and interlocking directorates.

As Chief of Staff of the Antitrust Division, Jimmy was a key advisor on policy changes, investigations, and enforcement efforts. He managed a team of advisors, oversaw work product ranging from articles to speeches, and represented the Division with fellow antitrust enforcers and within the DOJ. As Counsel, he advised senior leaders on a record-high docket of criminal investigations and litigation, including scores of recommendations to open and resolve investigations, grant leniency, and seek indictments. Additionally, he implemented policy changes to bring criminal charges for collusion in the labor markets, to incentivize and assess corporate compliance, and to create the Procurement Collusion Strike Force, an interagency effort to detect and prosecute cartels and fraud affecting government procurement. Jimmy also served as a criminal prosecutor during his stint at the DOJ.

Prior to his government service, Jimmy practiced in the antitrust department of a global law firm. After graduating from the Georgetown University Law Center, Jimmy was a law clerk for the Honorable Liam O’Grady of the U.S. District Court for the Eastern District of Virginia. During law school, Jimmy was a Charles H. March Fellow and law clerk for Federal Trade Commission Chairman Jon Leibowitz.
