Marco Rubio was finishing another marathon day campaigning Sunday, blitzing critical Virginia ahead of Tuesday's pivotal GOP presidential primary on a humorous note.
He was sticking with his all-out assault on leading GOP rival Donald Trump's character, vowing to "never let the Republican Party and conservative movement be taken over by a con artist."
Losing his voice after three sold-out rallies across the state, Rubio brought some new material to the heavily college-age audience of more than 3,000 at Roanoke College in Salem, Virginia, in the southwestern part of the state.
Rubio mocked Trump for his complexion, as he has before, accusing him of having a bad "spray tan."
Prompting cheers and laughter, Rubio said: "Donald is not going to make America great. He's going to make America orange!"
Ted Cruz, meanwhile, said it's "unfortunate" that Trump won't condemn former Ku Klux Klan leader David Duke, and said a white supremacist group is making robo-calls urging people, "Don't vote for the Cubans in the race."
Trump was asked during CNN's "State of the Union" whether he publicly condemns "the racism of former KKK Grand Wizard David Duke," who recently endorsed Trump.
Cruz told reporters Sunday in Oklahoma City that a white supremacist group is making pre-recorded calls supporting Trump and saying not to support Cuban-Americans like himself and Marco Rubio.
Cruz acknowledged that Trump can't control outside groups, but he said, "We should all be united in saying that the Klan is reprehensible."
