Glenn Greenwald, a columnist with The Guardian newspaper who closely communicates with Snowden and first reported on his intelligence leaks, told The Associated Press that the former NSA systems analyst has “literally thousands of documents” that constitute “basically the instruction manual for how the NSA is built.”
“In order to take documents with him that proved that what he was saying was true he had to take ones that included very sensitive, detailed blueprints of how the NSA does what they do,” Greenwald said in Brazil, adding that the interview was taking place about four hours after his last interaction with Snowden.
Snowden emerged from weeks of hiding in a Moscow airport Friday, and said he was willing to meet President Vladimir Putin’s condition that he stop leaking U.S. secrets if it means Russia would give him asylum until he can move on to Latin America.
Greenwald told the AP that Snowden has insisted the information from those documents not be made public. The journalist said it “would allow somebody who read them to know exactly how the NSA does what it does, which would in turn allow them to evade that surveillance or replicate it.”
