Jonathan Pollard was arrested in 1985 while working as a civilian analyst for the U.S. Navy, and he pleaded guilty to passing secret documents to the Israeli intelligence service. He has said he was motivated by loyalty to Israel, but he was also paid more than $50,000 and was in line to earn multiples of that amount if his spy work had continued.

A damage assessment by the CIA described Pollard’s espionage career as “short but intensive,” consisting of “biweekly deliveries of classified material,” including suitcases full of sensitive U.S. intelligence files on Arab, Pakistani and Soviet military capabilities.

He came under suspicion in part because of his efforts to gain access to classified material on such subjects despite a job that mainly entailed producing analytic work on North America and the Caribbean, the assessment said.
