"This is the best week, I think, so far in the Trump campaign, mostly because he's able to be himself, the authentic Donald Trump," Conway said on ABC's "This Week" on Sunday.

"But also the pivot that he's made is on substance. ... He's out there talking about law enforcement. He's talking about defeating radical Islamic terrorism, middle-class tax relief."

Conway touted the nominee for talking about his specific plans. She said people can disagree with him, but at least the public is now able to see more information about Trump's proposals.

"They can pull up his plan for middle-class tax relief," she said.

"They can say, 'Hey, this guy said we've had 33,000 murders by [the Islamic State in Iraq and Syria] and its predecessor groups since 2003 or so, 80 percent of them having occurred in the last three years since the birth and growth of ISIS happened.' He's at least willing to call them radical terrorists."
