Gail Slater, the head of the Justice Department's antitrust unit, said Thursday that she is stepping down from her post.
The move marks the end of a tenure that spanned a year during a period of heightened scrutiny over corporate consolidation and competition policy.
"It is with great sadness and abiding hope that I leave my role as AAG for Antitrust today," Slater wrote in a post on X. "It was indeed the honor of a lifetime to serve in this role.
"Huge thanks to all who supported me this past year, most especially the men and women of the Department."
The Justice Department did not immediately release additional details about her departure, including whether a successor has been named or who will serve in an acting capacity.
Attorney General Pam Bondi, in a statement, said, "On behalf of the Department of Justice, we thank Gail Slater for her service to the Antitrust Division which works to protect consumers, promote affordability, and expand economic opportunity."
As head of the Antitrust Division, Slater oversaw enforcement of federal laws designed to promote competition and curb monopolistic practices.
The division reviews major corporate mergers, investigates alleged anticompetitive conduct and brings civil and criminal cases involving price-fixing, bid-rigging and market allocation.
Her exit comes amid an era of aggressive antitrust enforcement in Washington, as regulators have taken a closer look at large technology firms, healthcare mergers and consolidation across multiple industries.
The Antitrust Division has played a central role in challenging mergers it believes would substantially lessen competition, as well as pursuing cases aimed at protecting consumers from higher prices and reduced choices.
Slater did not elaborate on her reasons for leaving.
The Antitrust Division, part of the Justice Department, works alongside the Federal Trade Commission to enforce federal antitrust laws.
Its leadership often shapes the administration's broader approach to competition policy and corporate oversight.
