Feb. 12 (UPI) — Gail Slater, the head of the Trump administration’s antitrust division in the Justice Department, announced that she is stepping down on Thursday.

Slater, 54, has served as assistant attorney general for the antitrust division for less than a year. She announced her departure in a post on X.

“It is with great sadness and abiding hope that I leave my role as AAG for Antitrust today,” Slater wrote. “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 Antitrust Division].”

Slater, who has a background in tech and media law. The Trump administration’s approach to enforcing antitrust laws and dealing with high profile corporate mergers has drawn scrutiny during her tenure.

President Donald Trump has thrust himself in the middle of merger talks during his term, including in December when he said he would be involved in reviewing Netflix’s acquisition of Warner Bros. Discovery.

Paramount executive David Ellison, son of Oracle CEO Larry Ellison, is pursuing a hostile takeover of Warner Bros. Discovery.

The Justice Department confirmed Slater’s resignation, thanking her for her service. The White House has not commented on Slater’s departure.
