Washington (CNN) Republican front-runner Donald Trump on Tuesday brushed aside demeaning comments from Marco Rubio about the size of his hands, saying others disagree with the Florida senator.

"He said I have small hands -- I'm actually 6'3", not 6'2" -- but I've always heard people say, 'Donald, you have the most beautiful hands,' " Trump said at a rally in Columbus, Ohio, on Super Tuesday

Trump was responding to an unusual attack from Rubio over the weekend.

"He's always calling me Little Marco. And I'll admit he's taller than me. He's like 6'2", which is why I don't understand why his hands are the size of someone who is 5'2"," Rubio said at a rally in Virginia Sunday night. "And you know what they say about men with small hands? You can't trust them."
