The National Security Agency is shaving personnel.

FOX News Radio's Steve Taylor reports from Washington DC:

National Security Directors

NSA Director Keith Alexander says the agency will stop using about 900 of the nearly 1,000 systems administrators who work for the agency; or like Edward Snowden, are hired as outside contractors. At a cyber security conference in New York, Alexander said NSA will use machines for jobs that machines are probably better at doing.

Alexander: "To make our networks more defensible and more secure."

An NSA official says the agency was planning the changes even before Snowden made secret information public, but now is making the cuts sooner.
