After several tweaks were suggested regarding the format for the upcoming Republican presidential debate, all participating parties have agreed upon the criteria for the Oct. 28, 2015 primary debate.

Reince Priebus, the chairman of the RNC, tweeted that everyone concerned had agreed that the upcoming debate, which will take place in Boulder, Colorado, will be two hours. There will be a 30-second closing statement for each candidate, and the debate will begin with an open-ended question to answer.

Recently two of the top tier Republican candidates threatened to not show up to the debates unless a strict time limit was imposed. A letter, signed by both Donald Trump and Ben Carson, sent to Mathew Cuddy, CNBC’s Washington Bureau Chief, said that, "Neither Mr. Trump or Dr. Carson will participate in your debate if it is longer than 120 minutes including commercials and does not include opening and closing statements.”

Aides from several GOP candidates have similarly insisted that the debates include opening and closing statements.

With 10 or more candidates on stage, the upcoming debate will be a crowded affair. Aside from Trump, and Carson, candidates such as Carly Fiorina, Marco Rubio, and Jeb Bush will all be vying for time.

Former business CEO and current politician Carly Fiorina criticized the demands made by Trump and Carson on a recent FOX interview, saying, "Well, I think apparently they're worried about answering questions for three hours."

"For heaven sakes, we have ten candidates on stage. I don't think three hours is a long time,” she added.

As Politico reports, Trump previously complained about the length of the GOP debate which was held at the Ronald Reagan Library, saying, "Three hours is too much, too long for a debate," and added, "How long is 'Gone with the Wind'?"
