Greenwald's reporting earlier this month sparked the scandal over NSA surveillance practices that is currently plaguing the Obama administration. The stories were based on classified documents leaked to him by former NSA contractor Edward Snowden, and Greenwald indicated Friday night that he's sitting on several more -- one of which he decided to talk about even though his story on it hasn't been published yet.
"It talks about a brand new technology that enables the national security agency to redirect into its own repositories one billion cell phone calls every single day. One billion cell phone calls every single day," he said.
"But what we're really talking about here is a localized system that prevents any form of electronic communication from taking place without its being stored and monitored by the National Security Agency," Greenwald continued. "It doesn't mean that they're listening to every call, it means they're storing every call and have the capability to listen to them at any time, and it does mean that they're collecting millions upon millions upon millions of our phone and email records."
