Trump Jr., who was appearing on the president’s favorite cable morning program to promote his new book, proceeded to re-enact one such conversation with his father — extending his thumb and little finger and holding his hand to his ear to mimic an incoming phone call from the West Wing.

“‘This is the White House operator. The president would like to speak to you,’” he said, adding: “‘Don, getting a little hot.’”

Trump Jr. acknowledged, however, that while he values his father’s counsel, the efforts to chill his posts online weren’t especially convincing given the president’s propensity for regularly firing off explosive tweets.

“I will take your advice on anything. I mean, this guy, you know, he gets it. He understands life, he understands people, he understands human nature. You know, you can really learn a lot from the guy. He's amazing,” Trump Jr. said.

“But I was like, this may be the one place where I'm just going to say, ‘I'm on my own, and maybe you don't have the authority to start talking about this.’”

Trump Jr. has emerged as a dogmatic defender of the White House since his father ascended to the presidency, employing his Twitter account to attack political rivals including New York Gov. Andrew Cuomo, Rep. Justin Amash (I-Mich.), and members of the progressive “squad” of freshman congresswomen.

But Trump Jr. has also faced criticism for sharing insensitive and occasionally conspiratorial messages on social media. He posted a photo to Instagram in September 2016 that featured a likeness of Pepe the Frog, a cartoon co-opted by supporters of white supremacy and anti-Semitism, and later that month ignited a days-long controversy by comparing the Syrian refugee crisis to a tainted bowl of Skittles.
