McDaniel spoke at the RNC’s winter meeting in Las Vegas behind closed doors on Friday, addressing a gathering of state chairmen and other top party members in what’s expected to be a critical swing state in the November election.

“We Republicans will stick together, as united as the union our party long ago fought to preserve,” McDaniel said, quoting Ronald Reagan, according to people who were in the room and disclosed her remarks on condition of anonymity to discuss a private gathering. “We’ll have our battles ahead of us, but they’re good battles, and they’re worth fighting for.”

McDaniel’s appeal for unity comes as former President Donald Trump and his allies push the party to get behind him and effectively end the primary even though he still faces a final major rival, former U.N. Ambassador Nikki Haley. While McDaniel has fought off opponents before, winning a competitive race for a fourth term as chairwoman last year, she’s now facing Trump supporters on the far right who are creating parallel efforts that could conflict with the national party.
