Tapper didn’t mention the KKK, he mentioned “certain hate groups”. As far as David Duke, Trump said his ear piece was not working right and he didn’t hear the name. Go back and watch the clip. When he found out that Duke was saying nice things about him he said he didn’t need his endorsment. He said the exact same thing back in August.

Go back and watch the video. Tapper clearly said David duke, KKK and Klu Klux Klan several times during the questioning. Trump showed no indication he was having problems hearing. He also knew who Duke was a few days before. Pretty weak excuses IMO.
