Right now the leaks APPEAR (nobody is saying much on the matter) to address only the Enhance Interrogation Techniques employed by the Bush administration.
There are a bunch of people at CIA that are afraid of that information, whether it's simple making-a-mountain-out-of-a-molehill or something more serious.
Either way, they don't want the information outed to Congress. The potential exists that Congress didn't get truthful testimony in the past.
