Back in 2019, Robert Mueller noted after he delivered his final report on the Russia investigation that the U.S. Department of Justice has a longstanding policy against prosecuting a sitting president.
According to an article by Jason Zengerle of the New York Times, Donald Trump Jr. is deeply concerned that if Joe Biden wins the election after his inauguration, he and other members of his family will then be prosecuted.

In his piece, Zengerle takes an in-depth look at the role that Trump Jr. has played in his father’s reelection campaign. An anonymous source, who Zengerle refers to as a “prominent conservative activist” told him, “Don’s the only person who thinks they’re going to lose. He’s like, ‘We’re losing, dude, and we’re going to get really hurt when we lose.’”
By “really hurt” the source says they are referring to criminal prosecution.

“An electoral defeat in November, Trump Jr. fears, could result in federal prosecutions of Trump, his family, and his political allies. He has told the conservative activist that he expects that a Biden administration will not participate in a ‘peaceful transition’ and instead, will ‘shoot the prisoners,” Zengerle wrote.

“When Trump ran for president in 2016, Trump Jr. — who is now 42 — was involved but hardly central to the effort,” Zengerle penned. “His sister Ivanka and her husband, Jared Kushner, exercised sweeping influence over the campaign. Trump Jr., by contrast, was assigned small, discrete tasks, like putting his outdoorsmanship on display in a pheasant-hunting photo-op with his brother, Eric.”

Zengerle then goes on to emphasize that four years later, Trump Jr. has become a major player in his father’s political career.
Jason Miller, a top advisor on Trump’s reelection campaign, “Don, Jr. represents the emotional center of the MAGA universe.”
Trump Jr. has also brought his girlfriend, Kimberly Guilfoyle, deep into Trump politics.
