Trump was sweating profusely, that’s the only indication anything had happened that I could see. Very calmly went on with the rally afterwards, ad libbed a few jokes and just proceeded.
He was sweating prior to the incident as well.
Except that Trump seemed to be sweating profusely even before the attack. So in reality, Trump appeared to me as if he just continued as before, as if nothing had happened, except for delivering the ad-libbed one-liner (!?!)
(wow, how is that for performance while under pressure?!)
(See maggief’s post of the link to the youtube video of the attack.)
He was sweating (for the past several rallies) because a bulletproof vest is real hot.
