Sen. J.D. Vance (R-OH) separated himself from his Republican colleagues by expressing his support for Federal Trade Commission Chairwoman Lina Khan, whose approach to antitrust has been criticized by the GOP.

Vance appeared at RemedyFest, an antitrust conference organized by Y Combinator and Bloomberg, on Tuesday alongside Sen. Elizabeth Warren (D-MA) and Khan. There, he spoke out in favor of Khan, who has been the target of Republicans over her abandonment of the consumer welfare standard that guided U.S. antitrust policy for decades in favor of a much more skeptical approach that also considers other factors, such as corporate concentration and income inequality.
