Glenn Greenwald: "Dianne Feinstein is Outright Lying" about NSA Surveillance Abuses

Greenwald, who broke the NSA surveillance stories, talks about the mystery around Edward Snowden and the Obama administration's decision to charge Snowden with espionage.

"What the NSA is doing is both unconstitutional and illegal," Greenwald says. "When Dianne Feinstein says into the camera that there is no evidence she is aware of that the NSA has abused its spying powers, she is simply lying."
