NSA Discloses Details Of Thwarted Terror Plots

WASHINGTON (CNN) — The director of the National Security Agency said Tuesday that he will provide details of two previously classified cases in which secret surveillance programs thwarted terrorist plots.Gen. Keith Alexander told the House Intelligence Committee that the plots were more than 50 that the programs helped prevent, and he would provide classified details of the others to the legislators.Panel Chairman Rep. Mike Rogers welcomed his testimony on the benefits of the secret programs.Last week, Alexander said the secret surveillance programs revealed in leaks of classified documents helped foil dozens of terror plots — but he offered no specific details.At the urging of the leaders of congressional intelligence committees, he looked into declassifying information on some cases to provide a stronger public defense of the programs that critics have called government overreach.
