A senior National Security Agency lawyer has said 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.
He added that the communications were being collected for both the NSA's 'PRISM' programme and for 'upstream' communications crossing the Internet, CNET reports.
According to the report, PRISM is a surveillance programme designed to collect and process 'foreign intelligence' that passes through American servers.
De explained to the board that 'PRISM was an internal government term that as the result of leaks became the public term,' the report said.
Tech firms consistently have denied participating in PRISM.
