"Traditional retail campaigning in the days and weeks leading up to the Iowa caucus is the Perry campaign's top priority," the statement said, as reported by USA Today. Perry, who has visited Trump at his NY office, "respects" the real estate mogul and Celebrity Apprentice star as well as "the folks at Newsmax," which is hosting the debate, airing on Ion. The news comes two days after Romney said he would not be able to take part because he will be too busy campaigning.

They predict it will be a media circus and a distraction from important issues. Huntsman said he believes the debate is just a publicity stunt. "This isn't about ratings for Donald Trump; this is about jobs for the American people," Huntsman told CNBC. Former House Speaker Newt Gingrich and former Pennsylvania Sen. Rick Santorum are the only two candidates to confirm their participation in the debate so far. PHOTOS: 10 Entertainers Democrats and Republicans Love to Hate Other candidates including Minnesota Rep. Michele Bachmann have yet to announce their decision. Earlier this week, she expressed concerns about Trump's objectivity, telling CBS' Early Show that "he said he's already learning towards a candidate." Trump made headlines earlier this year when he suggested that President Barack Obama is foreign-born while saying that he might run for president himself. In May, he announced he would not be running, saying: "Business is my greatest passion, and I am not ready to leave the private sector." Still, he has not ruled out a presidential bid as a third-party candidate.
