Energy Secretary Rick Perry, who clashed with Donald Trump during the 2016 presidential campaign, said the president does not hold a grudge.

"I've said some harsh things about the president," Perry conceded on Fox News. "He's a very forgiving man."

Asked about Republican unity, Perry, the former Texas governor, added: "I'm a big believer that our vision is the right vision for America."
