Debbie Feinstein heads Arnold & Porter's Global Antitrust group, and brings a wealth of experience to her practice in advising clients on a range of antitrust challenges before US antitrust authorities. She recently re-joined the firm from the US Federal Trade Commission (FTC), where she was Director of the Bureau of Competition. In that capacity, she was responsible for supervising the investigation and enforcement of the US antitrust laws against anticompetitive mergers and conduct. During her tenure from 2013 to 2017, the FTC had substantial litigation success and a number of major merger wins, including challenges to Sysco Corp.'s acquisition of rival US Foods Inc., and Staples Inc.'s merger with Office Depot Inc. She had previously served at the FTC from 1989 to 1991 as Assistant to the Director of the Bureau of Competition and Attorney Advisor.
Throughout her career, Ms. Feinstein has focused on merger and acquisition reviews by antitrust enforcement agencies in the United States and globally, as well as civil investigations and litigation. Her industry experience is broad, and includes retail, food, consumer products, healthcare, chemicals, and automotive parts, among others. She was an associate at Arnold & Porter from 1987 to 1989 and from 1991 to 1995. Later, as a partner, she led the firm's US Antitrust group from 2010 to 2013.
Ms. Feinstein has been consistently lauded as a leading practitioner by Chambers USA and other ranking publications. The National Law Journal named her one of the most influential women lawyers in America and Global Competition Review recognized her as global "Lawyer of the Year" and named her to its international list of the "Top 100 Women in Antitrust."
