Republican presidential candidate Mike Huckabee isn't letting Donald Trump and Ben Carson take all the credit for forcing CNBC to change its debate rules.

According to reports, a tense exchange occurred on the call when a top aide for Sen. Rand Paul, R-Ky., told CNBC they could "go f--- themselves" if they would not permit opening and closing statements.
