RNC plans to change rules to require candidates pledge not to participate in general election debates sponsored by the Commission on Presidential Debates

(CNN) The Republican National Committee said Thursday in a letter to the Commission on Presidential Debates that it is prepared to "prohibit future Republican nominees from participating in CPD-sponsored debates" unless the commission makes a number of significant changes to its procedure.
The letter, which was first reported by The New York Times, was signed by Republican National Committee chair Ronna McDaniel.
It was sent to commission co-chairs Frank J. Fahrenkopf and Kenneth Wollack, is the latest in a back-and-forth between the two groups over Republican accusations that the commission is biased.
CNN was first to report in June that McDaniel, in another letter to the commission, threatened to advise any future Republican nominee against participating in general election presidential debates unless significant changes are made by the commission.
The latest letter, which was sent on Thursday, escalates those threats and outlines actions the RNC plans to take.
"So long as the C.P.D.
appears intent on stonewalling the meaningful reforms necessary to restore its credibility with the Republican Party as a fair and nonpartisan actor, the R.N.C.
will take every step to ensure that future Republican presidential nominees are given that opportunity elsewhere," the RNC chair wrote.
