New Emails Suggest Google And NSA Cooperation

(Undated) -- There's new evidence suggesting Google and the National Security Agency once enjoyed a close working relationship. On Tuesday, Al Jazeera America published a series of email exchanges between former NSA director Keith Alexander and Google chairman Eric Schmidt. The correspondence pre-dates documents that were leaked by former NSA contractor Edward Snowden. Google continues to deny giving the U.S. government access to its servers.
