Watch CBS 60 Minutes interview with NSA leaders on Snowden leak

CBS 60 Minutes aired a report from NSA headquarters Sunday night, in which Gen. Keith Alexander said he had offered to resign following the Snowden breach, but the White House refused the resignation.

CBS touts the interview and its report inside the NSA as the deepest access afforded to a news organization. John Miller served as correspondent on the piece. Miller has bounced back and forth between the world of journalism and government service, having once worked in the office of the director of national intelligence and had been assistant director of public affairs for the FBI.

The NSA granted access "to help the American people understand what we're doing and why we're doing it," Alexander said. "And to put it simply, we're doing two things: We're defending this country from future terrorist attacks and we're defending our civil liberties and privacy. There's no reason that we would listen to the phone calls of Americans. There’s no intelligence value in that. There's no reason that we'd want to read their email. There is no intelligence value in that."
