"In 1977, Ames was assigned to handle him, and Fedorenko betrayed information about the Soviet missile program to Ames. The two men became good friends, hugging when Fedorenko was about to return to Moscow. "We had become close friends", said Ames. "We trusted each other completely."[58] Ames was initially hesitant to inform on his friend, but soon after handing over the majority of the information, he decided to betray Fedorenko to "do a good job" for the KGB.[56] Back in the USSR, Fedorenko used political connections to get himself out of trouble. Years later, Fedorenko met his friend Ames for an emotional reunion over lunch and promised to move to the U.S. for good. Ames promised to help. Shortly after lunch, Ames betrayed him to the KGB for a second time.[56] Fedorenko escaped arrest, defected, and is currently living in Rhode Island.[59]"
