A top adviser to former Republican presidential nominee Mitt Romney said Friday it was a mistake for the Republican National Committee (RNC) to ban NBC and CNN from hosting debates during the 2016 primaries, saying the unanimous vote would create "bad optics."

The RNC's decision to bar NBC and CNN from hosting debates is ostensibly a response to the networks' plans to air programming about former Secretary of State Hillary ClintonHillary Diane Rodham ClintonTrump can save Republicans and restore sanity to California in 2018 Breitbart News denies readership drop, alt-right label Mellman: The next war MORE, who is weighing whether she will seek the Democratic presidential nomination. CNN announced that it was planning to air a feature-length film about the former first lady, while NBC is considering a four-hour miniseries starring Diane Lane as Clinton.

"We don't have time for the media's games,” RNC Chairman Reince Priebus said Friday. “We’re done putting up with this nonsense. There are plenty of other news outlets.”

But Republicans are also hopeful that the move will enable them to limit the number of debates and have their candidates questioned by more friendly moderators, after a bloody 2012 nominating fight. Republican candidates participated in more than 20 debates before Romney was selected as the party's nominee.
