Nonprofit news organization ProPublica has partnered with the Guardian to report on documents leaked by former NSA contractor Edward Snowden, BuzzFeed reported on Sunday.

The news comes on the heels of BuzzFeed's exclusive report that the Guardian partnered with the New York Times after the UK paper was subjected to intense pressure and scrutiny from British authorities.

The Guardian's Glenn Greenwald was first to report on Snowden's leaked materials, unveiling massive secret surveillance programs that monitored global Internet data and U.S. phone records. Following his reports, the paper was forced to destroy hard drives of information in the presence of UK security officials. Greenwald's partner, David Miranda, was also detained while traveling through Heathrow Airport.

ProPublica president, Richard Tofel, told BuzzFeed in a statement that the investigative news organization "for some time has been working with the Guardian, and more recently also the New York Times" on a story based on Snowden's leaked documents. It appears as though ProPublica was involved with the Guardian before the New York Times was brought in as a partner.

Snowden recently accepted a year's asylum in Russia, where he has been for more than one month. A Russian newspaper reported on Monday that Snowden got stuck in the transit zone of a Moscow airport when Cuba would not let him enter the country and fly to Havana.
