The Washington Post was unbiased enough to print a time line of remarks from Trump over the last 25 years re David Duke. See link.
What I take from the interview that’s causing such flap is that Trump is stating he doesn’t personally know David Duke; he doesn’t actually know what groups are involved; he doesn’t exactly know what Duke has actually said about him…after all the many years of his statements not approving Duke, couldn’t they give him the benefit of the doubt that he really couldn’t clearly hear what was being asked in context? Oh, Clint Smith of the New Yorker wrote about how horrible it was to be black in Louisiana in the 90’s. And be the only black soccer player on his team. It was a typical article of its kind. No mention was made of the pandemic black crime rate in Louisiana that had people terrified; it was all just Southern racial hatred.
