In addition to his appellate expertise, Mr. Popofsky represented the United States in numerous antitrust merger and non-merger investigations and served as a Special Assistant United States Attorney in Alexandria, Virginia (the "Rocket Docket"). The 30 cases he tried, many of which involved expert witnesses, included securing felony convictions before juries.
