Have to admit that Republicans police their own and tolerate far less than Democrats accept from theirs.
One reason the Congressional Republicans dislike the President is his "everybody does time" policy. Used to be, if they got caught with their hands in the cookie jar, all they got was a slap on the hand. Now, they go to jail. Some of them probably wish they had Clinton back probably. Cronies love fellow cronies that let cronies do what cronies are wont to do.
I'm not so sure this guy Foggio is "one of their own".
Also, I don't believe this raid was conducted primarily for the Cunningham investigation. I think it's about leaks and Plame/Wilson-style rogue operations to hurt the Bush Administration.
