Got a link? I find it hard to believe he's wearing the same suit, shirt, & tie that he wore @ the convention. He's a rich guy with tons of suits and ties, I'm sure. But, maybe he is. (At least it looks like the same outfit. I saw it so much; the salute photo from the convention was all over the place the next day, and I watched part of the speech.) Even so, the original photo showed he knew how to salute, since it was with his right hand.
Well, as it happens. I saw a thing on TV last night that showed AGAIN the convention salute...and he was wearing a WHITE shirt, not a blue one like in this photo. So I stand corrected. This is obviously from a different occasion.
