Justice Department Antitrust Chief Slater Resigns 

The Justice Department’s top antitrust cop, Abigail Slater, resigned Thursday in a move that raises concerns that the Trump administration will soften its stance on challenging anticompetitive conduct by the biggest companies.

Slater’s announcement, posted to the website X, came after the White House requested her resignation, according to people familiar with the matter. She is departing just weeks before a trial over the department’s bid to force Live Nation Entertainment Inc. to sell off its ticketing arm, Ticketmaster. Justice officials also are poised to weigh in on Netflix Inc.’s plan to buy Warner Bros. Discovery Inc.
