GOP campaign operatives began arriving at the Hilton Alexandria Old Town at around 5:30 p.m. Sunday and headed upstairs to what had been code-named “family dinner.”

As the meeting got underway, senior strategists from several presidential campaigns revealed in e-mails and text messages that Priebus’s staff shake-up was not enough. One campaign manager, speaking about the private meeting on the condition of anonymity, wrote: “Major question is if the RNC should be involved at all.”

The campaigns reached an early consensus on one issue, according to several operatives in the room: the secure standing of Fox News Channel. Any changes would be applied to debates after next week’s Fox Business Network debate. Among the reasons, according to one operative in the room, was that “people are afraid to make Roger [Ailes] mad,” a reference to the network’s chief.

Bush campaign manager Danny Diaz recommended that Telemundo be reinstated after being dropped along with NBC. But the campaign of businessman Donald Trump, represented by manager Corey Lewandowski, threatened to boycott a debate if the Spanish-language network that Trump has clashed with was granted one.
