Story highlights Candidates threaten to boycott

The next GOP faceoff is Oct. 28, hosted by CNBC

(CNN) CNBC, the Republican National Committee and the GOP presidential campaigns have agreed to criteria for the October 28 primary debate in Boulder, Colorado.

RNC Chairman Reince Priebus tweeted that the parties have agreed to the following criteria: a two-hour debate, including commercials; a 30-second closing statement for each candidate; and a single, open-ended question at the beginning of the debate that each candidate will have the opportunity to answer.

The new criteria satisfies several of the campaigns' demands for opening and closing statements, as well a 120-minute cap on the debate time.

CNN reported earlier Friday that CNBC had agreed to limit its forthcoming Republican primary debate to two hours and allow for opening and/or closing statements, acquiescing to the public demands of Donald Trump and Ben Carson, and the private demands of several GOP campaigns.

Trump and Carson had threatened to pull out of the faceoff if the hosts didn't agree to their demands.
