She sat on the public benches with Hunter's half-sister Ashley and his wife Melissa Cohen, who also put their arms around him during breaks in proceedings.

A Biden family friend, Ricky Smith, who was in court, said: 'It ain't right for him (Hunter) to be sitting there because he was a drug addict.'

Hunter, the only surviving son of the president, has pleaded not guilty to three charges relating to buying a .38-caliber Colt Cobra revolver at a time when, according to his own memoir, he was in the midst of crack addiction.

The charges are lying to a federally licensed gun dealer, making a false claim on an application by saying he was not a drug user, and illegally having the gun for 11 days.

If found guilty he could face up to 25 years in prison, although as a first-time offender he could also escape any jail time.

After going through security at the six-story J. Caleb Boggs Federal Building in downtown Wilmington, Delaware, Hunter passed a large photograph of his smiling father on the lobby.

The building itself is named after the Republican politician - Boggs - who Joe Biden beat to become a U.S. senator in 1972.

Potential jurors dismissed included several who knew the Biden's personally.

One of them had played squash with Beau Biden, Hunter's late brother, and was a member of the same country club as the Bidens.

Another had been a work colleague of Jill Biden's at a school where she taught, and said he had met 'Jill's husband numerous times.

Several also said they knew Hallie Biden, Beau's widow, who had a relationship with Hunter and is set to be a key witness in the trial.

Other jurors said they were at least familiar with this case and the Bidens because Wilmington was a 'small place'.

One said: 'I live in Delaware. You can't swing a cat with out hearing something.'

Among the jurors sent home was a woman who said she had formed an opinion about Hunter Biden based on media reports.

She said: 'It's not a good one.'
