I think that Clarisse Feldman, at American Thinker, who used to post on FreeRepublic as Fedora, has a whole lot of information on Hagel and his Middle Eastern connections. She hasn’t posted on FreeRepublic in a very long time, so I suggest that you contact her at American Thinker.
The first hit that I got on Fedora and Chuck Hagel is this -Chuck Hagel: $1,000 from IAPAC to the Hagel for Senate Committee on 10/02/2006 (Iranian Ameican Pac).
Hagel, as I recall was tightly involved with Elias Aburdene, who was also tightly tied to Joe Wilson.
I don’t have time to get into all this, but I strongly suggest that you contact Fedora (Clarisse Feldman, at American Thinker) She’s a wonderful source.
