On January 29th , 2008, Congress heard testimony on enforcement of Federal espionage laws. Former FBI official David G. Major told a House Judiciary Committee panel that espionage remains "a very real threat to U.S. national security." He said, "Since the end of the Cold War, there have been 78 individuals arrested for espionage or espionage-related crimes and since the 21st century began, there have been 37 individuals arrested in the US as agents of foreign powers." In his testimony, Mr. Major, now President of the private Counterintelligence Centre, presented a convenient tabulation of "Agents of Foreign Powers Arrested in the United States in the 21st Century"
Recent espionage cases were also reviewed at the House Committee hearing by J. Patrick Rowan of the Department of Justice and Larry M. Wortzel of the US-China Economic and Security Review Commission.
