Donald Trump Jr. Don John Trump'Tiger King' star Joe Exotic requests pardon from Trump: 'Be my hero please' Zaid Jilani discusses Trump's move to cancel racial sensitivity training at federal agencies Trump International Hotel in Vancouver closes permanently MORE responded to claims of coordinated efforts within the White House to undermine his father during an interview with Hill.TV on Thursday.

“Recent news reports that there are figures in your father’s White House that were trying to subvert his will or his policies. Do you think that that’s a problem?” asked Hill.TV’s Saagar Enjeti on Thursday.

“It’s a major problem because that is directly subverting the will of the people,” Trump Jr. said, adding that such figures are motivated by these actions because they see the “establishment culture being attacked.”

“People think they know better — they haven’t done it, they were never elected but they think they know better, but it’s really about them covering their future in the uncertainty of what happens after the age of Trump,” he added later.

Trump Jr.’s comments come in light of a new book written by an anonymous author who served as a senior official in the Trump administration.

The book, set to be released next week, was written by the same anonymous author who wrote a New York Times op-ed last year, claiming that there were coordinated efforts from White House staff to “thwart” Trump’s worst inclinations.

In the new book, the author makes a number of bombshell claims, including that Trump repeatedly proposed to get rid of judges.

The White House and Trump have continuously condemned the anonymous author.

“Man up, come out,” Trump Jr. said, addressing the anonymous author in his Hill.TV interview. “Say it.”

Trump Jr. joined "Rising" to tout his own book, "Triggered: How the Left Thrives on Hate and Wants to Silence Us."
