The tech giants implicated in the PRISM program have repeatedly denied offering access, but new documents reveal the NSA footed the bill for compliance costs. New information about the actions of the U.S. National Security Agency and its now PRISM data-tapping program has surfaced on Friday. In a new report by The Guardian, NSA is said to have paid "millions" of U.S. Dollars to foot the bill in covering compliance costs for the tech companies implicated to be data sources for PRISM.

In early June, The Guardian and the Washington Post published stories reporting that the federal agency was mining data from the following nine technology industry giants: Microsoft, Yahoo, Google, Facebook, AOL, Skype, YouTube, Apple, and video chat room community PalTalk.

The companies listed as the data sources have issued public statements denying any involvement in PRISM.
