The two leading Republican presidential contenders, front-runner Donald Trump and No. 2 Ben Carson, on Thursday threatened to pull out of the third GOP debate in Colorado later this month in a dispute with CNBC and the Republican National Committee over its rules.
Trump took to Twitter after a conference call Thursday afternoon between RNC officials and top advisers to the candidates erupted into chaos over the issues, Politico reports. 
Both Trump and Carson were particularly concerned about the debate’s length and whether candidates would be allowed to make opening and closing statements.
The Carson camp fired off a letter to CNBC Washington Bureau Chief Matthew Cuddy on behalf of both campaigns. The third debate will be held on Oct. 28 at the University of Colorado-Boulder.
“Mr. Trump and Dr. Carson do agree to a 120 minute debate that includes commercial breaks and opening and closing statements,” the campaign said in the letter, a copy of which was provided to Newsmax. “Mr. Trump and Dr. Carson do not, and will not, agree to appear at a debate that is more than 120 minutes long including commercials breaks.
“Further, the debate must include opening and closing statements from all the candidates,” the letter said.
“The criteria that was outlined by CNBC was never discussed with any of the candidates or the campaigns,” Corey Lewandowski, Trump’s campaign manager, told The New York Times.  “So what CNBC did was send out a memo and said, ‘Here’s the criteria as you have approved them’ and that went out to all the campaigns.
Jason Miller, a strategist for Texas Sen. Ted Cruz, said that the campaign would consider not participating if opening and closing statements were not allowed. (my emphasis)
