"Donald Trump is an unstable charlatan who is appealing to the worst instincts in people, and I believe ultimately, the American people are going to reject that," O'Malley, who ended his own campaign in February, said on Sunday. 

"That's why many self respecting Republicans are not supporting Donald Trump for president." 

Panel member former Arizona Gov. Jan Brewer shot back, saying "every time you disagree with [Democrats] you're a bigot or you're a racist." 

"Dang it, I get fed up that we hear over and over and over again from the president of the United States that every time someone wants to support the Constitution and the rule of law that we are out there because we are racists and bigots."

"He jumps immediately to the race card, the racist card, in particular," Cuccinelli said. 

"It's a common tactic for Democrats," he said, adding that he plans to vote for Trump in November.
