It's already public: http://www.dawn.com/news/1077275/nsa-tapped-into-undersea-ca...
I know, it only makes sense in NSA's distorted rhetoric but if this is disputed in a court, that is what you're going to hear (that the information is not public, as in, it should not be disclosed).
Any US citizens propagating this information would probably be in big trouble precisely because of that. I am not sure about this, but IIRC, US citizens may even get in trouble for reading this information if they lack proper clearance.
I can go to Wikileaks and read Snowden and Assange-backed papers all day long. Govt. employees on the other hand aren't allowed to read that info even though it's already public (even at home, even on their own time).
