Last week, the former Utah governor announced that he would forgo an upcoming Republican presidential primary debate sponsored by Newsmax magazine and moderated by Trump and instead attend an unmoderated one-on-one debate against rival Newt Gingrich.
Huntsman and Trump have been feuding ever since Trump said Huntsman asked for a sit-down with him — which, according to Trump, he declined. Huntsman's camp denied that it had ever reached out to Trump for a sit-down or backing at all.
In the same interview, Huntsman said if Trump, who himself mulled a presidential bid but ultimately decided against it, had any courage, he would actually be running for president.
"This is exactly what's wrong with politics. It's show business over substance," Huntsman continued. "If he had any courage at all, he would be running for president of the United States of America as opposed to manipulating issues from the other side.
"This is about real issues. The presidency of the United States of America is more important than these silly game shows and reality shows."
Earlier on Monday during an interview with MSNBC, Trump said that Huntsman would sooner or later say that he reached out to the real estate mogul for a sit-down.
"I’m sure he’ll tell the truth about that because he’s a Mormon," Trump said.
