“I wouldn't do it. I think it would be stupid,” Trump Jr. said on "Fox & Friends" Thursday morning.

“I don't think any proper lawyer would say, ‘Hey, you should go do it,’ because it's not about collusion anymore,” he continued, referring to Mueller's probe into whether the Trump campaign colluded with Moscow during the presidential election.

“It’s about, ‘Can we get him to say something that may be interpreted as somewhat off or inaccurate, and after 50,000 questions, maybe you make a mistake, and that's how we get you,' and that's ridiculous.”

The president's eldest son also voiced his distrust of Mueller's team.

"The reality is the greatest investigative bodies in the world have been looking for two years — two years — and they have come up with nothing," he added.

Trump Jr.'s comments come amid escalating tensions between his father and the special counsel.

The president has referred to Mueller's probe as a "witch hunt" on numerous occasions and repeatedly called for an end to the investigation.

Trump has also targeted the makeup of Mueller's team, referring to its members derisively as "13 Angry Democrats."

"At what point does this soon to be $20,000,000 Witch Hunt, composed of 13 Angry and Heavily Conflicted Democrats and two people who have worked for Obama for 8 years, STOP!" Trump tweeted last month after The New York Times published a bombshell report saying that Trump Jr. had met with George Nader, an emissary for the crown princes of the United Arab Emirates and Saudi Arabia, during the 2016 campaign.

Nader, according to The Times, told Trump Jr. that the crown princes were willing to help Trump win the election.

Trump's lawyer, Rudy Giuliani, has floated the possibility of the president sitting for an interview with Mueller if the special counsel's questions meet certain conditions.

Giuliani told the Associated Press last week that Trump would only sit with Mueller if he first sees documents pertaining to the FBI's use of an informant during the campaign.

“That will not change,” Giuliani said. “We are not going to budge.”

Giuliani also said Trump's legal team is preparing to send a formal demand to Mueller for documents related to the Russia probe.

The president has repeatedly suggested that the FBI planted a spy in his campaign, a claim for which he has no evidence. Trump has also suggested that the investigation into possible collusion between his campaign and the Kremlin is nothing more than a politically motivated scheme that stemmed from the Obama administration.
