Damn, pretty intense.
So was the pretense of that rally "let's storm the capitol" because if so you might say common sense would tell you to steer clear if you're a public figure. If it was and he missed the memo, probably still a bad look for him to attend, he just picked the absolute worst rally to go show his support for Trump. There's plenty of celebrities who openly support Trump but it seems like John Maus and Ariel Pink were the only two who showed up to that rally...
