Monday Julian Assange, founder of the WikiLeaks organization, which he said is advising Snowden, was asked by ABC News if there were concerns the trove of information on Snowden's laptops could fall into the wrong hands. Without elaborating, Assange said that the material "has been secured by the relevant journalist organizations prior to travel."
Today Glenn Greenwald, a column for The Guardian who broke the first of the NSA stories based on Snowden's information, went further, telling The Daily Beast that Snowden had taken extraordinary precautions by sending highly encrypted files to several people for insurance. The recipients would only be allowed to open the file should something happen to Snowden, Greenwald said, so that the stories would still get out.
Putin reportedly said today Russian security services have not, and will not, work with Snowden.

"I think we're all just collectively waiting to see where the music stops, to see where he lands," she said. "It's the most epic game of Marco Polo ever."
