Kushner, on the heels of Trump's United Arab Emirates-Israel peace deal, called his father-in-law the "results president."

"The Democratic convention, you’re going to see a lot of politicians who have been doing this for a long time, complaining about problems that quite frankly they haven’t solved so you’ll hear a lot of complaints," Kushner said.

"But what you’ll hear about during President Trump’s convention is a lot of the successes that he’s had," Kushner added. "He’s a results president. He’s a businessman president."

The White House senior adviser, who previously served on the campaign in 2016, said the issues Trump is running on this year are different from the last election against Hillary Clinton "because he solved a lot of the issues."

Kushner is joining Trump on a trip to Arizona on Tuesday celebrating the 300th mile of the U.S.-Mexico border wall.

"Border crossings are down significantly. The southern border is more secure than its ever been," Kushner said. "The two parties have different views on issues like immigration, but President Trump's had great successes in that space and in many other spaces, so I think he set the foundation for where this country has the potential to go."
