Career
Mr. Weingarten is a seasoned trial lawyer who has served as first chair trial counsel and lead counsel in federal courts and federal agency administrative proceedings. He has significant experience in antitrust matters, both conduct and merger related, including most recently serving as first chair trial counsel representing the Federal Trade Commission (FTC) in federal court and administrative proceedings challenging anticompetitive mergers and conduct. He also has experience litigating competition matters across industries, with a focus on the healthcare, pharmaceutical and technology sectors.
James held various other positions at the FTC after joining the agency in 2017. In those roles, he investigated and litigated significant merger and non-merger matters on behalf of the government.
