I love all this meaningless bullshit how the media tries to hang the reputation of other people on a politician just because the othe rperson "endorses" them. It's a fucking game they play on republicans but when republicans bring up the reputations and histories of people that Democrats ACTUALLY KNOW AND ASSOCIATE WITH, the press mocks it as a dirty trick and refuse to cover it. Example the admitted terrorist bomber Bill Ayers. Obama got away with pretending he barely knew the guy which is far from the truth.
Trump (who I hate and refuse to vote for) should refuse to answer the question and tell the press to go fuck themselves. David Duke or the Klan or whomever doesn't have anything to do with him. He shouldn't be forced to denounce them multiple times. They endorsed him, he didn't come out and endorse them. The press is the attack arm of the Democrat party. Most of the American people know it and that's why they are rejecting the mainstream media. Tell them the press to fuck off and get back on topic discussing real issues. Call them out on their games, Trump usually does but for some reason he let them catch him up in this one.
