Education
Brennan attended Fordham University, graduating with a B.A. in political science in 1977.[3] While a college student, in 1976, he voted for the Communist Party USA candidate for president, Gus Hall. He has later described his vote as a way of “signaling my unhappiness with the system”, specifically the partisanship of the Watergate era.[19] After Fordham, Brennan attended the University of Texas at Austin, receiving a Master of Arts in government with a concentration in Middle East studies in 1980.[6] He speaks Arabic fluently.[8] His studies included a junior year abroad learning Arabic and taking courses at the American University in Cairo.[3][6]
While riding a bus to class at Fordham, he saw an ad in The New York Times that said that the CIA was recruiting. He decided that a CIA career would be a good match for his “wanderlust” and his desire for public service.[6] He applied to the CIA in 1980. During his application he admitted during a lie-detector test that he had voted for the Communist Party candidate four years earlier. To his surprise, he was still accepted; he later said that he finds it heartening that the CIA valued freedom of speech.[20]
Yes. I think this is what put him on the KGB radar, and likely led to his recruitment.
His alarm has definitely been turned off!!!!!
