NSA Chief Admits Stunning Surveillance Ambition

National Security Agency Director Keith Alexander said the NSA wants to collect more phone records, even after being the subject of recent public unease.

Sen. Mark Udall (D-Colo.) asked Alexander if the NSA wants "the phone records of all Americans" during a congressional hearing Thursday.

"I believe it is in the nation's best interest to put all the phone records into a lockbox that we can search when the nation needs to do it, yes," Alexander replied.
