America's Most Notorious Spy - The Robert Hanssen story

Robert Hanssen was an FBI agent who became one of the most notorious spies in U.S. history, secretly selling classified information to the Soviet Union and Russia for over 20 years. His betrayal compromised national security, exposed double agents, and led to the deaths of American operatives. He was arrested in 2001 after an internal investigation uncovered his espionage, and he later pleaded guilty to avoid the death penalty.
