Biden says he will NOT pardon son Hunter if he is found guilty of buying a gun while addicted to drugs and insists Trump got a 'fair trial'

President Joe Biden said in a new interview Thursday that he would not pardon his son Hunter Biden, who's on federal trial this week on gun charges. 

Biden sat down with ABC News' David Muir and answered 'yes' when the journalist asked if he would accept the outcome of Hunter's trial, which has seen a parade of the first son's ex-lovers as witnesses.

The president also answered 'yes' when Muir asked Biden if he would rule out pardoning his son. 

Biden also said he believed former President Donald Trump - his 2024 rival - received a fair trial. 

'He's trying to undermine it,' The president said. 'He got a fair trial. The jury spoke.' 

A week ago, Trump was convicted on all 34 counts of falsifying business records related to hush money payments made to porn star Stormy Daniels ahead of the 2016 presidential election.

Since the conviction, Trump has maintained that the process was rigged and referred to himself as a 'political prisoner.' 

On Newsmax Tuesday night, the ex-president and presumptive Republican nominee even went as far as to float he could put his political enemies in jail. 

'So, you know, it's a terrible, terrible path that they're leading us to, and it's very possible that it's going to have to happen to them,' Trump said. 'Does that mean the next president president does it them? That's really the question.' 

Trump's trial concluded just four days before Hunter's kicked off in federal court in Wilmington, Delaware. 

The younger Biden is accused of lying to a federally licensed gun dealer, making a false claim on the application used to screen firearms applicants where he said he was not a drug user and illegally having the gun for 11 days.

But at the time, Hunter was addicted to crack cocaine - as he laid out in his 2021 memoir Beautiful Things. 

The president spent Monday, the first day of his son's trial, hunkered down at his Wilmington lakefront home, while other Biden family members have gone to the courthouse to show support. 

First lady Jill Biden was there for several days.

Hunter's sister Ashley also attended, as did Peter Neal, Naomi Biden's husband and the president's sister, Valerie Biden Owens.

Hunter's wife Melissa Cohen was also on hand and attracted headlines when she referred to a former Trump aide who was at the courthouse as a 'Nazi piece of s***.' 

Witnesses called, so far, include a number of Hunter's exes - Hallie Biden, the widow of brother Beau Biden, Kathleen Buhle, his first wife and mother of three of his children and Zoe Kestan, an ex-girlfriend who he met at a strip club.

The president flew to Paris overnight Tuesday and attended the D-Day commemoration in Normandy Thursday.

He was interviewed by Muir on the sidelines of the trip.
