Trump ridicules Kasich's 'disgusting' eating habits

Donald Trump mercilessly mocked rival John Kasich in Rhode Island Monday, labeling his eating "disgusting" and calling him "stubborn" for remaining in the race.

Speaking in front of a rally crowd in Warwick, Trump says of Kasich that "I have never seen a human being eat in such a disgusting fashion."

He continued: "This guy takes a pancake and he's shoving in his mouth." That's not presidential, Trump added.

The billionaire developer was referring to Kasich's morning conversation with reporters while eating. Trump said he'd been watching television with his youngest son Barron when Barron told his father, "'Daddy look.' I said, 'Don't watch! Little bites, little bites.'"

Trump also called Kasich stubborn and compared him to a child for refusing to exit the race when he has no chance of winning without a contested convention. He also took aim at Ted Cruz, saying: "when he's under pressure he's like a basket case."
