Warren has extensive experience investigating and litigating cases involving mail and wire fraud; bank fraud; fraud on federally funded programs; the Food, Drug and Cosmetic Act (FDCA); the Foreign Corrupt Practices Act (FCPA) and False Claims Act (FCA); and the full panoply of federal and state environmental laws. He has led internal investigations for a broad range of clients, including, most recently, a U.S.-based financial services and insurance company, an India-based generic pharmaceutical company, and the South American subsidiary of a major U.S.-based retailer. Warren’s clients have also included attorneys and major law firms that face particularly complex challenges as they navigate government investigations while protecting client privileges and meeting their confidentiality obligations. In addition to the demands of managing a national practice, recent investigations and enforcement actions have taken Warren to locations in Europe, South and Central America, Singapore, Africa, and India.
Warren has also represented print and broadcast media in libel cases, reporter’s privilege cases, and press access matters in federal court, and has acted as pre-publication advisor to media companies worldwide. He has also counseled clients on creating and implementing records and information management programs as part of the full suite of policies that are best practices in information governance.
