Demanding to know the criteria for the event…..

The two frontrunners of the Republican presidential race are threatening to boycott the upcoming CNBC presidential debate if the network doesn’t limit the time for the candidates to be on stage.

In a joint letter to CNBC, Donald Trump and Ben Carson indicated that they would only agree to a 120 minute debate (including commercials) with time for opening and closing statements.

“To be clear, neither of our campaigns agreed to either the length you propose or your ban on opening and closing statements,” the letter read. “In fact, neither of our campaigns were even consulted.”

“Neither of those conditions are acceptable. 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,” the signed letter, published by NBC, read.
