On Tuesday, March 11, 2025, the Senate confirmed Gail Slater as the Assistant Attorney General for the U.S. Department of Justice (DOJ) Antitrust Division (Division). While Slater has been circumspect in her public comments regarding past and anticipated Division priorities, her prior experience and recent statements offer early insights into her expected approach.

A second Trump administration brings some uncertainty about the trajectory of non-merger antitrust enforcement. Under the Biden administration, the Federal Trade Commission (FTC) and the Antitrust Division of the Department of Justice (DOJ) took an aggressive approach to antitrust enforcement across several industries and were particularly hostile to mergers and acquisitions. President Trump’s nominees to lead the antitrust agencies signal that the new administration is likely to continue current levels of vigorous antitrust enforcement—particularly in Big Tech and other hot-button industries—but will likely relax M&A enforcement and return to more predictable and traditional tools and theories of harm.
