Here’s a preview of a new podcast I think you’ll enjoy. Amid the nuclear threat of the Cold War, America's prized secrets were falling into the hands of its sworn enemy—the Kremlin. The FBI's hunt for the leak led to an astonishing discovery—the mole was one of its own, special agent Robert Hanssen. For two decades, Hanssen masqueraded as a devoted patriot while ruthlessly selling out his country, trading classified intelligence to the Soviet Union and later Russia, in exchange for cash and diamonds. He was a whirlwind of contradictions—a self-proclaimed patriot and a traitor; a family man who sexually betrayed his wife; an ardent man of God and a sinner. In this CBS News limited series, CBS News Chief Washington Correspondent Major Garrett delves into the double life of Robert Hanssen and unravels the chilling truth about the most damaging spy in FBI history. Listen to Agent of Betrayal: The Double Life of Robert Hanssen wherever you get your podcasts.
