Jeb Bush called GOP rival Donald Trump “buffoon”, a “clown” and an “a**hole” during a meeting with a donor, according to reports.
According to Politico, the scathing words came after Trump retweeted a comment about Bush’s wife, Columba Bush, who is Mexican-American.
One of Trump’s fans wrote on Twitter that “Bush has to like Mexican illegals because of his wife,” which Trump then shared with his followers.
The two men will meet in Thursday night’s Republican debate, where all eyes will be on frontrunner Donald Trump.
His rivals have been getting advice on how to deal with him.
“You should treat Trump seriously,” Rudy Giuliani said on CNN.
Pat Buchanan added on CNBC: “I would challenge Trump.”
According to a recent article in Vanity Fair, Bush has lost 40 pounds on the Paleo diet.
