NSA Lawyer Says Tech Firms Knew of Surveillance

The top lawyer for the National Security Agency and others from the Obama administration made it clear to the U.S. government's independent oversight board that tech titans knew about government surveillance while it was going on. NSA general counsel Rajesh De told the Privacy and Civil Liberties Oversight Board that tech titans were aware that the NSA was collecting communications and related metadata both for the NSA's "PRISM" program and for "upstream" communications crossing the Internet.
