"We've had our own arguments, you know that," he told CBS "Face The Nation" host John Dickerson. "It's politics. I don't really care. What I care about is winning."
Priebus said that he cared more about the outcome of the presidential election and down-ballot races than hypothetical backlash.
"Post-Tuesday, I'm not worried about that," he said.
Priebus also claimed that Trump is "doing well in black communities."
"We need to give him credit for all of his attempts," Priebus said. "He went up to Detroit. He went to Cleveland."
Most polls show Trump trailing Clinton significantly among black voters, polling as low as 1 percent.
