Trying to pry information loose from the NSA is nearly impossible. The ODNI has been dropping documents related to the NSA's various surveillance programs, but that's as a result of a lawsuit, something that goes completely unacknowledged at the ODNI's site. People requesting a peek into what the NSA has collected on them PERSONALLY have been universally met with a boilerplate response that "neither confirms nor denies" the existence of this data.
MuckRock has been filing dozens of FOIA requests in hopes of freeing up info on the many contractors employed by the NSA. Unsurprisingly, this has met with little success. While it did manage to secure 16 pages on French security firm Vupen, its other requests have been met with claims that no responsive documents have been found. This is hard to believe considering some of the requests are about known NSA contractors.
