Greenwald says it best:
Rockefeller is not just any Democrat. He is the individual whom the Democratic Senate caucus thereafter elected -- and still chooses -- to lead them on all matters relating to intelligence. Just consider how compromised he is and they are when it comes to investigating abuses by the intelligence community over the last six years. Rockefeller was complicit in all of those abuses, and the Democrats voted for him -- and still support him -- as their Chairman of the Senate Intelligence Committee. How can Rockefeller possibly preside over meaningful investigations into conduct and policies -- including the destruction of the videotapes and the conduct which those videotapes would reveal -- of which he approved? And how can Senate Democrats pretend to be outraged at such policies when the leader they chose supports them?
