Beave, three observations
1, He was adjusting his jacket
2, If he was making a WP sign, it was calling in artillery fire of White Phosperous rounds in on DNC Hq.
3. This is an example of the idiocy on the Internet. Unfortunately, there are equally idiotic posts from the Conservative side as well.
I don’t think you took into account that Miller never wears shorts, but always wears a long sleeve shirts and a jacket to hide all his white power tattoos (end sarcasm here).
