Anderson Cooper has long traded on his biography, carving a niche for himself as the most human of news anchors. But there's one aspect of his past that the silver-haired CNN star has never made public: the months he spent training for a career with the Central Intelligence Agency.

Following his sophomore and junior years at Yale—a well-known recruiting ground for the CIA—Cooper spent his summers interning at the agency's monolithic headquarters in Langley, Virginia, in a program for students interested in intelligence work. His involvement with the agency ended there, and he chose not to pursue a job with the agency after graduation, according to a CNN spokeswoman, who confirmed details of Cooper's CIA involvement to Radar.
