At a campaign event in Purcellville, VA covered live by MSNBC, Marco Rubio said that the fact that former KKK "grand wizard" David Duke has endorsed Donald Trump for president makes him "unelectable."
MARCO RUBIO: [In the 2000 election], one of the reasons why [Donald Trump] said he wasn't going to run is because David Duke was part of the Reform Party.
He knows exactly what David Duke is. He was asked this morning two times, will you repudiate and condemn the Ku Klux Klan. He refused to do that as well.
We cannot be a party that nominates one who won't condemn white supremacists, and the KKK, we cannot be a party who does that.
By the way, not only does -- not only is that wrong, it makes him unelectable. How will we grow a party with a nominee that refuses to condemn the Ku Klux Klan? Don't tell me he doesn't know who it is.
This is serious. What we are facing today is the most important election in a generation. We need to nominate someone that can win, because if we don't win, what that means is Bernie Sanders or Hillary Clinton will be the next president of the United States.
