Republican National Committee Chairman Reince Priebus praised Donald TrumpDonald John TrumpBiden says his faith is 'bedrock foundation of my life' after Trump claim Coronavirus talks on life support as parties dig in, pass blame Ohio governor tests negative in second coronavirus test MORE, saying the GOP presidential nominee has been on message and has shown maturity as a candidate in the last week.


"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."

But Priebus said he expects Trump to start rising in the polls.

"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."

Priebus continued to praise Trump, saying he's on a "great pathway to recalibrating the campaign and getting this thing tight."

"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."
