Rick began his career in the 1980s in the Antitrust Division of the U.S. Department of Justice, becoming the Assistant Attorney General in charge of the Division from 1986-89 – the youngest person ever to be confirmed by the Senate to that position.  Over the last 30+ years since leaving the Division, Rick has led the antitrust practices at several leading D.C. and New York firms including Covington & Burling and Paul, Weiss.

During his time in private practice, Rick has represented major multi-national companies and executives in virtually every industry – from, among others, agricultural and animal health (Monsanto, Elanco) to energy (ExxonMobil) to defense contractors (Northrop Grumman, United Technologies) to professional sports (NFL, NBA, MLB) to technology platforms (Microsoft, Nuance) to pharmaceutical manufacturers (Eli Lilly, Pfizer) to health insurers (Cigna).

Rick has represented his clients before the Antitrust Division, the Federal Trade Commission, State Attorneys General and major foreign antitrust regulators in connection with many of the most notable merger investigations, including Exxon’s merger with Mobil, US Airways’ merger with American Airlines, and Cigna’s acquisition of Express Scripts.  At the same time, Rick has represented clients in some of most prominent government investigations of the last quarter century, including leading the team that settled the Government’s monopolization case against Microsoft and defending international companies and executives in major antitrust criminal investigations.

For four decades, Rick has been at the forefront of antitrust law and is uniquely capable of advising clients on the antitrust regulatory environment affecting the way they do business globally. As agencies and rules have evolved, he has helped clients to understand the dynamic legal framework, to assess the legal risk and rewards associated with a range of competitive strategies, and to work with government bodies to take advantage of, and ensure appropriate compliance with, the regulations governing the clients’ chosen strategy.
