“Gov. Perry has talked to Donald TrumpDonald TrumpTrump mocks Murkowski, Cheney election chances Race debate grips Congress US reentry to Paris agreement adds momentum to cities' sustainability efforts MORE in recent days and respects him and the folks at Newsmax very much,” said campaign manager Ray Sullivan in a statement. “In the coming weeks, Gov. Perry will be in Iowa almost continually, meeting with real voters, doing town-hall meetings and events and talking American jobs, faith and overhauling Washington, D.C., to Iowa voters.”

The campaign also pointed out that there are two debates in the next seven days.

On Thursday, Republican National Committee Chairman Reince Priebus cautioned the candidates against participating in the Dec. 27 Newsmax-ION debate, which will be held in Des Moines, Iowa, and is the final debate before the Jan. 3 caucuses, saying there’s a conflict of interest because Trump still might run as an Independent candidate.

“I wouldn’t recommend [participating],” Priebus said. “But I would also say to the candidates they can do what they want to do … but I would agree that having the person be the moderator who is still talking about running as an Independent — I think that’s a problem.”

Trump has said that if he isn’t happy with the Republican nominee for president, he might launch an Independent bid for the Oval Office.

So far only Newt Gingrich and Rick Santorum have said they’ll participate.

Jon Huntsman, who has had an ongoing spat with Trump, immediately declined.

The Ron Paul campaign strongly denounced the event, saying it was below the office of the presidency.

“The selection of a reality television personality to host a presidential debate that voters nationwide will be watching is beneath the office of the presidency and flies in the face of that office’s history and dignity,” Ron Paul 2012 national campaign chairman Jesse Benton said. “To be sure, Mr. Trump’s participation will contribute to an unwanted circus-like atmosphere.”

On Wednesday, Mitt Romney said he called Trump to inform him that he was too busy campaigning to make the debate.
