I don't know and really don't care but I have seen public pictures of him from that day on with no bandage and a perfectly healed ear. He might as well have cut himself shaving.
It still doesn't temper the fact that a shooter was able to get into position at a political rally under Secret Services' watch. That is the important thing here and needs to not happen ever again..
That guy hasn't told the truth since he crawled out of his mother's womb and he's not going to start now. If a high powered rifle round even so much as nicked him, he'd sill be at Walter Reed today..
