The Fake Job that Trapped FBI Agent Robert Hanssen in Moscow Spy Scandal

Robert Hanssen, one of the most damaging spies in the history of the FBI, leaked top secrets to Moscow for nearly 20 years - betrayals that the agency says cost lives. Hanssen had studied Russian in college and began working for the FBI in 1976. Within a decade, he was double-crossing the bureau. Starting in 1985, Hanssen operated as a destructive mole within the US government, selling top secret documents to the USSR and Russia, and compromising the identities of undercover spies.
