He said he was busy with his "other" committee.
He was busy with a sub-committee.
If I were Lugar, then I'd respond, "Well, George, if you're so busy, then maybe I should do something about it and take you off this committee. Wouldn't want you to be overworked." That would be the least he could do, seeing how Voinovich stabbed him in the back.
Never happen, of course.
I wonder which other committee kept 'Voinoswitch" away from the Bolton hearing?
