On the campaign trail, Florida Senator Marco Rubio criticized Trump’s remarks refusing to disavow backing from former KKK member David Duke.

Sen. Marco Rubio: “He’s unelectable now. He refused to criticize the Ku Klux Klan. He’s now been given three interviews. This morning on the Today Show, he blamed it on a bad earpiece, that he couldn’t hear the question. I don’t care how bad the earpiece is, Ku Klux Klan comes through pretty clearly, and he refused to criticize it.”
