Nope. I do think his words were a poor choice, plus it shows how much of an idiot he is, but I know that he was not supporting white supremacy during that press conference. But I do believe that in many other ways, he has demonstrated himself to be a racist and a white supremacist.
And no, I am not spending the time going over that, listing examples, or listing links for you to copy/paste.
But go ahead and type his name + racist into the search engine of your choice.
