(The Hill) — The Republican National Committee alerted the Commission on Presidential Debates on Thursday that it plans to require GOP candidates not to attend debates run by the commission going forward. 

“The RNC will initiate the process of amending the Rules of the Republican Party at our upcoming Winter Meeting to prohibit future Republican nominees from participating in CPD-sponsored debates,” wrote Chairwoman Ronna Romney McDaniel in the letter, which was obtained by The Hill. 

McDaniel wrote the GOP voters “have lost trust” in the commission and noted that the RNC has proposed a number of reforms to the debate process.

“Unfortunately, neither the tone nor substance of your latest response inspires confidence that the CPD will meaningfully address the serious issues which the RNC has raised,” she said. 

If the RNC moves to change its rules, the pullout would mark one of the greatest changes in the history of U.S. presidential debates. 

McDaniel detailed the timeline of the RNC’s communications with the commission, which included a letter sent from the committee to the commission in June and discussions between the commission’s co-chair Frank Fahrenkopf and David Bossie, the chair of the RNC’s temporary presidential debates committee. 

Fahrenkopf served as RNC chairman in the 1980s. 

McDaniel said the commission’s response to the RNC’s list of demands “so far seem designed to delay any reform until it is too late to matter for the 2024 election.” 

The Commission on Presidential Debates responded in a statement on Thursday, noting that it “deals directly with candidates for president and vice president who qualify for participation.” 

“The C.P.D.’s plans for 2024 will be based on fairness, neutrality and a firm commitment to help the American public learn about the candidates and the issues,” the commission said. 

According to the RNC’s letter, the CPD pushed back on the RNC’s request to appoint a nonvoting observer from the RNC or DNC to attend its board meetings. 

“In furtherance of our position as a nonpartisan, neutral body, which neither favors nor disfavors any party or candidate, we do not negotiate the terms or conditions of our operations with anyone,” a letter from the commission, obtained by The New York Times, read. 

This is not the first time Republicans have voiced criticism about the commission. Most recently, former President Trump complained that moderators in the 2020 presidential debates were biased against him, while in 2016 he singled out one of the commission’s co-chairs, Mike McCurry, for previously working as a press secretary in the Clinton administration.
