Matthews asked him tonight, “Is Donald Trump honest when he says that Barack Obama isn’t a legitimate president?”

Trump repeatedly refused to answer the question, saying that once he answers it, “that’s all people want to talk about.” So no, he did not give a straight answer to whether Obama’s a legitimate president.

Matthews told him, “I think it’s a blemish––I think it’s your original sin. I’m an American, I think the president should be respected! I think there’s a little ethnic aspect to it, I don’t like it!”
