Jeffrey Alexander Sterling
Jeffrey Alexander Sterling is an American lawyer and former CIA employee who was arrested, charged, and convicted of violating the Espionage Act for revealing details about Operation Merlin (a covert operation to supply Iran with flawed nuclear warhead blueprints) to journalist James Risen. Sterling claimed he was prosecuted as punishment for filing a race discrimination lawsuit against the CIA. The case was based on what the judge called "very powerful circumstantial evidence." In May 2015, Sterling was sentenced to 3½ years in prison.
