This webpage has a link to a pdf listing the credentials committee members and giving their bios. I didn't read the whole page; I wasn't really interested in what the poster had to say, just a list of the committee members, so I'm not endorsing or agreeing with what the poster said, nor the website itself (which I've heard of but never read before).
There are some Clinton admin people on there (the chair is Alexis Herman), but there are also Dean and Edwards people on it, and others who are local officials (including a state senator from Montana, I think it was).
