Most recently, he was a partner in the Government Enforcement and White Collar Crime practice at Skadden Arps Slate Meagher & Flom. As a white collar criminal defense lawyer, he handled a wide range of matters including criminal antitrust, securities, mail, wire, accounting, bank, health care and customs fraud, tax evasion, Foreign Corrupt Practices Act (FCPA), money laundering, and Racketeer Influenced and Corrupt Organizations Act (RICO) prosecutions. He has extensive experience in handling cross-border, internal, and government-facing investigations. During his time at Skadden, Warren was repeatedly selected for inclusion in Chambers USA as well as The Best Lawyers in America, and Who’s Who Legal.
In private practice, Warren led dozens of cross-border internal investigations for multinational corporations, touching more than 20 countries in Europe, Asia, and Latin America, many related to the FCPA and other anti-corruption laws. Deeply experienced in FCPA matters, Warren frequently advised on FCPA due diligence in connection with M&A and other corporate transactions, and often spoke on legal and industry panels covering a broad spectrum of FCPA matters.
