Has the NSA been tracking the cellphone movements of millions of Americans?
Sen. Ron Wyden (D-Ore.) suggested on Thursday that the National Security Agency tracked or considered tracking the cellphone location data of millions of people in the United States.
During a Senate Intelligence Committee hearing, Wyden asked NSA Director Gen. Keith Alexander whether "the NSA has ever collected — or made any plans to collect — Americans' cell site information in bulk."
As a member of the Intelligence Committee, Wyden has access to classified information about the NSA's surveillance programs. . . .
Analyzing which cell towers a phone has connected to can allow law enforcement or intelligence officials to track the location of the phone's owner.
Wyden has been a long-time critic of NSA surveillance, but government secrecy has limited his ability to publicly discuss his concerns. . . .
