Gail Slater said on Feb. 12 that she is resigning from her role leading the Department of Justice’s (DOJ) antitrust litigation.

“It is with great sadness and abiding hope that I leave my role as [assistant attorney general] for antitrust today,” she said in a post to social media.

“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 @justiceatr,” she added, using the X handle for the Antitrust Division.

Slater entered the department in March as the administration pursued multiple high-profile antitrust cases against tech giants. During her tenure, the Justice Department litigated potential changes to Google’s search business following its landmark loss in an antitrust lawsuit brought during Trump’s first administration.

Attorney General Pam Bondi thanked Slater for her service.

“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,” she said in a statement provided to The Epoch Times..

Slater promoted what she described as a conservative vision for antitrust enforcement. Among other values she promoted was a preference for “litigation over regulation.”

“Aggressive antitrust enforcement supports a competitive process that enables markets to regulate themselves, providing a bulwark against market power that often leads to regulatory intervention,” she said in prepared remarks from April.

President Donald Trump had positioned her appointment as a way to continue his efforts at countering Big Tech.

“Big Tech has run wild for years, stifling competition in our most innovative sector and, as we all know, using its market power to crack down on the rights of so many Americans, as well as those of Little Tech,” Trump said in a TruthSocial post from December of 2024.

“I was proud to fight these abuses in my First Term, and our Department of Justice’s antitrust team will continue that work under Gail’s leadership.”

Slater previously worked for the Federal Trade Commission and as an economic adviser to then-Sen. JD Vance (R-Ohio). She also worked at Fox and Roku.
