The head of the NSA faced questions about the agency's surveillance program during congressional testimony Wednesday. He said the program has been 'critical' to national security.
The US government’s top-secret phone call-monitoring programs revealed in leaks to the media have helped to foil “dozens” of terrorist attacks on US soil, according to the head of the National Security Agency (NSA).
On Capitol Hill Wednesday for a previously scheduled hearing to discuss cyberoperations, Gen. Keith Alexander, the head of the NSA, argued to lawmakers that the secret surveillance program has been “critical” to national security.
That said, the clandestine agency is also endeavoring to be “transparent” with the American people, General Alexander assured lawmakers.
