Corporate executives of several companies identified in the leaked documents told "The Guardian" that they had no knowledge of the PRISM program in particular and also denied making information available to the government on the scale alleged by news reports. Statements of several of the companies named in the leaked documents were reported by TechCrunch and "The Washington Post" as follows:   In response to the technology companies' confirmation of the NSA being able to directly access the companies' servers, "The New York Times" reported that sources had stated the NSA was gathering the surveillance data from the companies using other technical means in response to court orders for specific sets of data. "The Washington Post" suggested, "It is possible that the conflict between the PRISM slides and the company spokesmen is the result of imprecision on the part of the NSA author. In another classified report obtained by The Post, the arrangement is described as allowing 'collection managers [to send] content tasking instructions directly to equipment installed at company-controlled locations,' rather than directly to company servers." "[I]n context, 'direct' is more likely to mean that the NSA is receiving data sent to them deliberately by the tech companies, as opposed to intercepting communications as they're transmitted to some other destination. "If these companies received an order under the FISA amendments act, they are forbidden by law from disclosing having received the order and disclosing any information about the order at all," Mark Rumold, staff attorney at the Electronic Frontier Foundation, told ABC News. On May 28, 2013, Google was ordered by United States District Court Judge Susan Illston to comply with a National Security Letter issued by the FBI to provide user data without a warrant. Kurt Opsahl, a senior staff attorney at the Electronic Frontier Foundation, in an interview with VentureBeat said, "I certainly appreciate that Google put out a transparency report, but it appears that the transparency didn't include this. I wouldn't be surprised if they were subject to a gag order." "The New York Times" reported on June 7, 2013, that "Twitter declined to make it easier for the government. But other companies were more compliant, according to people briefed on the negotiations." The other companies held discussions with national security personnel on how to make data available more efficiently and securely. In some cases, these companies made modifications to their systems in support of the intelligence collection effort. The dialogues have continued in recent months, as General Martin Dempsey, the chairman of the Joint Chiefs of Staff, has met with executives including those at Facebook, Microsoft, Google and Intel.
