The leaking McCarthy was one such conversion and per post #149, a great link by Freeper Jane Austin gives positions converted, although names are not named.
No, McCarthy was a career CIA employee. She joined the Agency in 1984 as an analyst. Most of the NSC is comprised of career employees from State, DOD, CIA, and other agencies. Usually, the various agencies nominate people for these jobs. Their nominations are reviewed by the NSC Director and approved/disapproved. Even though McCarthy was in a political appointee position, i.e., the President could appoint whomever he wanted, she was still in the CIA.
