The NSA's stance on the single letter reflects its position on the larger issue of surveillance, maintained Shahid Buttar, director of grassroots advocacy for the Electronic Frontier Foundation.
"Snowden has claimed from the beginning that he shared word in official channels that there were oversight problems," he told TechNewsWorld.
"The agency denied he shared word and now there are documents showing he did. That reflects the narrative of the underlying abuses themselves, which the agency denied and said didn't exist," Buttar added. "It's part of a continuing cycle of official denial of fact."
