Donald Trump blamed a “lousy earpiece” for why he claimed he didn’t know who David Duke was during a CNN interview on Sunday. On NBC’s Today show Monday, Trump said he knows who Duke is (a former Grand Wizard of the Ku Klux Klan who will vote for him), but claimed he never met him. Trump also said he only didn’t know the white-supremacist groups that host Jake Tapper asked him about. Nevertheless, Trump refused several opportunities to denounce the racists supporting him. On Sunday night, he tweeted that he disavowed their support.
