The Pentagon Papers
When the US Government tried to suppress the publication of the Pentagon papers it didn't go so well. I see no difference in what the New York Times did in the 70's and what Assange did now.

And for the prosecution and possible conviction of Assange to stand the USSC would have to re-visit and overturn their decision, New York Times Co. v. United States.
