Sen. Mark Udall (D-CO), a member of the Senate Intelligence Committee, on Sunday called on the government to curb the National Security Agency's spying abilities.
"The arguments for the status quo, George, fell apart this week in Washington," Udall said on ABC's "This Week." "This is an invasion of privacy. If you take the business records of every American, of all of our phone calls, you can get a pretty good idea of what people are doing, based on when they call, who they call, from where they call."
Udall conceded that the President's advisory panel on surveillance did not find any abuse within the NSA, but the senator still argued for surveillance reform.
"There has been no abuse. But the potential for abuse is always there, and Americans have always erred on the side of protecting our privacy," he said. "The heart of our belief in freedom is the freedom to be left alone, and part of that freedom to be left alone is privacy."
