As a federal prosecutor for seven years in the Criminal Division of the U.S. Attorney’s Office in Los Angeles, Adam served as Deputy Chief of the Office’s Government Fraud, Public Corruption and Civil Rights Section, where he supervised a wide range of criminal cases and trained federal prosecutors on trial advocacy, investigative techniques, and grand jury practice.
