RNC Chairman Reince Priebus said that Donald Trump firing campaign manager Corey Lewandowksi was a pivot in the right direction, and the type of "professionalization" that will make Trump competitive against Hillary Clinton.

"There was a lot of loyalty but I think you get to the point where you say, look, we've got the presidency of the United States on the line," Priebus told On the Record. "I think this pivot, this seriousness that you're seeing right now, I think everyone should look at this and say 'This is good.'"

Priebus also said that Paul Manafort, who will assume Lewandowski's duties, is a "pro."

He also compared the RNC to the DNC, saying the former has a stronger infrastructure and ground game.

"We’ve done I think a great job in getting our operation to a place that it hasn’t been in decades," he said.
