Found it--
The gang of four are the congressional leaders on the Congression intelligence commitees (Senate and House)
Bob Graham
Richard Shelby
Pelosi and Goss
Which reminds me, Bob Graham gave an interview here in miam on WIOD that he was not informed about water boardi8ng himself, and Bob Graham is a notorious note keeper. In fact, he "proved" to the CIA that the CIA claimed to have held meetings that never occured.
I found that a bit interesting that the Senate was left out of knowing the type of techniques that were being used but the House was fully informed.
WIOD is a conservative Talk Radio Station. I doubt that if the Republican Senator Graham was playing partisan politics, he would make mention of some questionable claims by the CIA that could be used to build Pelosi case.
They got one date wrong, there were more then one date of the briefings, at least keep up.
