Ex-Trump aide Cliff Sims laughs as CNN reads him the president's angry tweet in real time

Former Trump White House aide Cliff Sims on Tuesday laughed out loud as host Alisyn Camerota read President Donald Trump's tweet attacking him in real time on CNN.

Sims, who has been hitting the cable news circuit to promote his scathing tell-all book "Team of Vipers," appeared on CNN Tuesday to talk about some of the craziest experiences he'd had in the Trump White House.

As he was talking, Trump angrily tweeted about Sims and attacked him for not honoring the nondisclosure agreement he signed before he came to work for the White House.

"A low level staffer that I hardly knew named Cliff Sims wrote yet another boring book based on made up stories and fiction," the president wrote. "He pretended to be an insider when in fact he was nothing more than a gofer. He signed a non-disclosure agreement. He is a mess!"

After Camerota read Sims the tweet, he just laughed it off.

"There it is!" he said. "I knew this was a possibility when I wrote this book. You know what I said? My identity is not wrapped up in being a Trump staffer, my identity is wrapped up in my faith."

"You don't mind being called a 'gofer?'" Camerota asked him.

"Not one bit!" he replied.
