Recent Antitrust Enforcer Statements Signal New Administration’s Direction and Priorities
Assistant Attorney General Gail Slater of the Department of Justice, and Chairman Andrew Ferguson and Commissioner Mark Meador of the Federal Trade Commission, have each looked to the history of conservative voices to chart a path forward for antitrust enforcement in the second Trump Administration. Within the last three weeks, AAG Slater delivered remarks to the University of Notre Dame Law School, Chairman Ferguson delivered remarks at the International Competition Network Annual Conference, and Commissioner Meador shared his policy aims in an FTC paper and a speech to George Washington University. The enforcers emphasized the need for robust antitrust enforcement to break private monopolies and other anticompetitive arrangements. These enforcers appear to align on priorities, though differing slightly in methods, grounding their rationale in what they describe as traditional conservative values, while at the same time distancing themselves from previous Republican administrations which have emphasized anti-cartel policies and an otherwise preference for limited intervention in markets.
