His Hagel your Senator? I don't have all the links for that here, right now. I'm not at home and haven't been saving anything that I've been researching. Sorry.
What I remember is that Aburdene is a campaign contributor to Hagel through one of his PACs. But if you look further, you will see that Hagel has been part of a bunch of commissions to all parts of the world, and oddly enough the name Aburdene pops up among the other members of the commission. It is my guess that these are all members of the same family.
