13. Robert Hanssen’s Spy Scandal
Robert Hanssen, a former FBI agent, was arrested in 2001 for espionage after providing the Soviet Union and later Russia with classified information over two decades. Operating under the alias “Ramon Garcia,” he compromised numerous U.S. intelligence operations, leading to the exposure and execution of at least three Soviet agents working for the U.S. Hanssen received over $1.4 million in cash, diamonds, and Rolex watches for his betrayal. He was sentenced to life imprisonment without the possibility of parole (fbi.gov).
