I'm really curious to know who the heavy-set guy was.
Me too. He looked to be a man in his 60's. Not really obese, but on the heavy side. White hair. Civilian. He and GWB had quite a conversation. Looked to me like the man might have been reporting something to the President or briefing him on something.
GWB went straight to that man after greeting Allen and Honore, and he only acknowledge Nagin afterwards. I supposed it's possible the man might have been a representative from the governor, but without a reporter cluing us in, I can only speculate.
