He was in Washington for a while, then moved back to Arkansas in January of this year.
http://www.arktimes.com/030124coverstoryb.htmlThere is a lot of information about Stephens at From the Wilderness. (FTW is, in my humble opinion, a little bit tin foil, but I don't think they make stuff up. Your mileage may vary about that.)
I am firmly convinced that Stephens is a dubious character. He is a Presidential kingmaker going back at least to Carter. He backs both Democrats and Republicans, and he has connections to almost every major scandal you could name. I was sad to learn of Clark's connection with him, BUT--it could be nothing. We'll see.
