Not trying to make this a party issue but that is 1 GOP rep who has been subjected to torture. Considering the GOP released a rebuttal to the report, I think it is a fair statement to say in turn that they are effectively supporting the use of torture by the US [1].

Edit: 1. http://www.msnbc.com/msnbc/republicans-dismiss-senate-tortur...

Marco Rubio has come out in support of the actions of the CIA; who is to say he doesn't represent the party line on this issue more than McCain?

(and really, McCain is one of few Republicans who doesn't support torture because of his own background as a POW)

Is McCain's opinion shared by the rest of the Republicans? If so, then getting justice done should not be a problem. My impression is that McCain is pretty alone, though.
