Doha Mekki is a seasoned antitrust lawyer, former public servant, and ex-Justice Department enforcer. She has spent her career advancing competition and fair dealing in key sectors and markets across the U.S. economy. Most recently, she held the top roles in the U.S. Department of Justice’s Antitrust Division, serving until earlier this year as the Acting Assistant Attorney General — the agency’s top antitrust official. She served previously as Principal Deputy Assistant Attorney General, the division’s second-in-command, where she supervised civil and criminal enforcement, litigation and trial, appeals, domestic and international policy, competition advocacy, and its economic and expert analysis programs.

During her tenure, the Department filed more monopolization cases than it had in nearly four decades. Mekki oversaw the investigation and litigation of landmark cases to stop monopolies, corporate collusion, criminal cartels, and illegal mergers and acquisitions.

She played a central role in building the department’s cases against Google, Apple, Ticketmaster/Live Nation RealPage, Visa, and corporations in the airline, publishing, agriculture, supply chain, and industrial sectors. She also led efforts to crack down on algorithmic collusion and labor market conspiracies like wage fixing and no poach agreements that harm workers.

She began her career in the antitrust and financial services groups of an international law firm in New York. She holds a B.A. from Duke University, a J.D. from the University of Pennsylvania Law School, and a Masters in Bioethics from the University of Pennsylvania’s Perelman School of Medicine. Born in Sudan and raised in Charlotte, North Carolina, she brings to her work a lifelong commitment to advancing the cause of justice and economic liberty for people of all stripes.
