Kate Patchen, the assistant general counsel of competition at Meta Platforms and the former chief of the San Francisco office of the U.S. Department of Justice’s Antitrust Division, joined Covington & Burling as the Washington, D.C.-headquartered firm continues to recruit government attorneys for its antitrust practice.

Patchen joined the firm as a partner in its antitrust practice last week. She will start in Covington’s New York office and anticipates soon moving to the firm’s San Francisco office.
