Republican Party leader Reince Priebus says the last week shows that Donald Trump has the ability to stay on message.



"I think that he is getting into a groove. I think he likes the new style that he has been out on the campaign trail producing and speaking of," Priebus said on ABC's "This Week." "So I think he's done great."



"What you're going to see is these polls will begin to tighten in the next couple of weeks," he said.



"And by Labor Day or thereafter, I think you're going to be back to an even race if we continue down this path."



"And I obviously just saw Kellyanne Conway do, I think, a really fantastic job in pivoting and showing the direction of this campaign that we're going," Priebus said about her interview earlier on the show.



"And Donald Trump has been disciplined and mature. And I think he's going to get this thing back on track. And also tight and ahead as we move through September."
