Career
Following two judicial clerkships, including one on the Supreme Court of the United States (for Hon. Antonin Scalia), Stephen served nine years as a federal prosecutor in the U.S. Attorneys’ Offices in the Southern District of New York and the Eastern District of Pennsylvania. He handled wide-ranging international investigations as a prosecutor, conducting and supervising innovative investigations of violations of the Foreign Corrupt Practices Act (FCPA) and federal export regulations. Among other successes, Stephen investigated and prosecuted individuals who exported sensitive technology to Iran in violation of export controls, uncovered and prosecuted widespread fraud in the United Nations Oil-for-Food Program, and thwarted efforts by Hezbollah to obtain thousands of heat-seeking missiles and machine guns from sources inside the United States.
In addition to his unique investigative and trial experience, Stephen has exceptional abilities as an appellate lawyer. He has briefed and argued appeals before the U.S. Courts of Appeals for the 2nd, 3rd, 7th, and Federal Circuits, and has also briefed matters in multiple state Supreme Courts and the Supreme Court of the United States.
