Hunter Biden, 54, is accused of buying a Colt Cobra .38-caliber revolver in October 2018 while failing to disclose his illegal drug use and illegally possessing the weapon for 11 days.

He has pleaded not guilty to three felony charges.

The case, led by US Special Counsel David Weiss, a Trump appointee, is one of two criminal cases against Biden.

The trial comes after the historic conviction of former President Donald Trump on March 31.

A federal tax trial for Hunter Biden began with the swearing in of 12 jurors and four alternates by US District Judge Maryellen Noreika.

The case is centered around Hunter Biden's past crack cocaine use and addiction, which he has publicly discussed and was featured in his 2021 autobiography.

Hunter Biden claims to have been sober since mid-2019.

Republicans have used Hunter Biden's legal issues to divert attention from Donald Trump's own legal woes, as Trump is due to be sentenced on July 11 for his criminal cases.

Jill Biden, Melissa Cohen Biden, and Ashley Biden were present in court.

Joe Biden, the President of the United States, made a statement expressing pride in his son Hunter's recovery from addiction.

The trial of Hunter Biden, who has faced allegations of corrupt business dealings, included several jurors with personal experience with addiction.

Some jurors shared that they had friends or family members who struggled with substance abuse.

Despite efforts by Congressional Republicans to find evidence of a corrupt link between Hunter Biden's foreign business dealings and his father's political power, few jurors expressed strong political views.

A few jurors mentioned being acquainted with members of the extended Biden family.

A potential juror in the trial of Hunter Biden revealed that she and her husband know him.

Hunter Biden could face up to 25 years in prison if convicted on all charges in the Delaware case.

Prosecutors aim to prove that Biden lied on a federal gun purchase form regarding drug use.

They may use evidence from his phone and iCloud account, including photos of him using crack and messages with drug dealers.

Hunter Biden's former wife, Kathleen Buhle, may testify against him in an upcoming trial, alleging he squandered money on drugs, alcohol, and prostitutes during their divorce in 2017.

Biden's lawyers plan to present evidence of his completion of a drug rehabilitation program before purchasing a gun and argue that his answer on the gun purchase form was truthful.

A plea agreement that could have resolved the gun and tax charges without prison time fell through last year due to questions about the immunity it granted to Biden.

Biden's team blamed Republican pressure for the agreement's failure.

Recently, Judge Noreika, a Trump appointee, issued orders that seemed to undermine Biden's legal strategy, granting requests from prosecutors.

A judge ruled against the defense introducing expert testimony that people with substance abuse disorders may not recognize themselves as addicts during Joe Biden's trial for lying on his background check form.

This testimony could have helped Biden argue that he was unaware he was being dishonest.

The government must prove that Biden knowingly lied for the charges to stand.
