Given Coleman's State, and his obvious political savvy, I would think it odd that he would just be out there on a fishing expedition. He obviously was not play out so sort of media grandstanding.
My guess is that there is something very real to his findings. Even Levin was on a short leash.
Galloway might have just wanted to have a face to face with his co-religionists over here to get some sort of idea what he was in for.
I think you're right. I just posted before seeing your comments that my recollection was that Galloway decided to appear after the documentation was released last week.
