At the time of his defection, Pacepa simultaneously had the rank of advisor to President Nicolae Ceaușescu, acting chief of his foreign intelligence service, and a parliamentary undersecretary at Romania's Ministry of Interior.
Subsequently, he worked with the American Central Intelligence Agency (CIA) in operations against the former Eastern Bloc. The CIA described his cooperation as "an important and unique contribution to the United States". Provided by Wikipedia
