It's too early to come to any conclusions, and I should have been in bed already, but still, if, as the media say, there were 9 shots fired, I am surprised that only his ear was injured. But if the shooter is a liberal/antifa, it makes more sense.
Could be that he was hit more than once but was wearing bullet proof gear. I don't know much about these things, just something that occurred to me.
Gotta say though, I was super impressed that at a time like that, Trump could still think about his followers, acknowledge them and show strength.
