No, Cheney was seated by Pres Bush. While he had a cowboy hat on, too, the guy I was talking about was at the very top row, looked like next to Louie Gohmert.
I saw a photo of the guy you're talking about a couple of hours ago, and thought about your comment.
You're right. That wasn't Cheney. The mystery guy had on a full brim western hat, while Cheney wore a small brim western hat, and was seated elsewhere.
