A Trump supporter yells white power twice in a video, and Trump retweets it, that means he watched it and liked it. This is the type of thing that keep his handlers up at night, when his aides saw the retweeted video it was like a "5 alarm fire", they tried to reach him to get him to take it down, but couldn't reach him, he was golfing, three and a half hours later someone finally got hold of him and he deleted it. Nothing lese in the video matters, it was just a lot of cursing and name calling anyway, but Trump is telling you who he is, he doesn't care, he's telling you who he is
You mean nothing else in the video matters to you.
Except someone likely being a sarcastic asshole to some liberal lunatic calling him a racist.
