Trump senior adviser Paul Manafort said Trump and Priebus were “communicating frequently” and communicating better these days. “They don’t agree on everything but they agree to try to work things out and they are working things out,” he said.

An RNC member close to Priebus agreed.

“They’re not best buddies or anything but they have a pretty good relationship,” the member said. “I consider all this back and forth as a little bit of ‘heat of the battle’ tensions.”

Trump’s complaints about the party’s system have prompted some of his own supporters to roll their eyes in dismay.

“He ain’t read the rules,” said Ada Fisher, a retired physician and Republican National Committee member from North Carolina, who was wearing a Trump button at the Florida event.
