After filling out the jury questionnaire, the first panel of prospective jurors are being brought into the court room one-by-one to face individual questioning from the judge and both parties. As of about 9:45 a.m. ET, the court had made it through the questioning of just six jurors.

The prospective jurors so far have include a woman who worked with the Secret Service for over two decades and whose husband was a uniformed officer in Washington, D.C., at locations including the White House.

One prospective juror who volunteered for Hilary Clinton's 2008 campaign prompted the first mention of President Joe Biden -- though not by name.

Judge Norieka asked that prospective juror if her work volunteering and donating to Democratic campaigns would prevent her from being fair in a case that involved "the son of the Democratic president of the United States."

She said it would not.

The exchange occurred as first lady Jill Biden sat in the front row of the gallery, watching intently as each juror answered their questions. The first lady is sitting next to Hunter Biden's wife, Melissa.

Earlier, a prospective juror was struck for cause because of his firm views on guns, after he told the judge he thought gun ownership was a "God-given right." He said he would not be able to be impartial in a case where someone was prevented from buying a gun due to federal law.

Hunter Biden's arrival through the front entrance of the J. Caleb Boggs Federal Building this morning means he would have passed an enormous portrait of his father, which hangs in every federal courthouse in the country.

The first batch of 50 jurors were sworn in by Judge Noreika, who instructed them not to discuss the case with anyone, including family, or to conduct any research on the case or to read any news about it.

Reporters monitoring the proceedings from the overflow room could not hear most of Noreika's statement due to technical difficulties. As technicians tried to fix the issue, they turned on a TV that happened to be playing an attack ad against Joe Biden.

Hunter Biden has arrived at the courthouse for the start of his federal gun trial this morning.

His stepmother, first lady Jill Biden, is attending the proceedings.

Two hundred and fifty Delaware residents have been summoned to the courthouse in downtown Wilmington, where they will face typical questions about their fitness to serve as jurors.

But because this is the trial of the son of a sitting president, there will be some novel topics covered during the jury selection process known as "voir dire."

Among the questions jurors will be asked: "If you were eligible to vote in any election(s) in which Joseph R. Biden was a candidate, would that fact prevent you from maintaining an open, impartial mind until all of the evidence is presented, and the instructions of the Court are given?"

And "Do you believe Robert Hunter Biden is being prosecuted in this case because his father is the President of the United States and a candidate for President?"

The day's final witness was Ed Banner, the 80-year-old Navy veteran who recovered Hunter Biden's firearm from the trash receptacle outside a supermarket after Hunter Biden's then-girlfriend Hallie Biden had disposed of it there.

Banner described finding the firearm and other items as he was rummaging for recyclables that he would often drive to New York to return for money.

Defense attorney Abbe Lowell had previously suggested that cocaine residue discovered on a leather pouch that held the gun could have been tampered with between the time the firearm was discarded on Oct. 23, 2018, and when it was tested in a lab in late 2023.

"This may sound like an unusual question, but does anyone in your household use cocaine?" Derek Hines asked Banner.

"No," Banner said, appearing somewhat surprised by the question.

Banner also denied wrapping the firearm in a sock, as a Delaware state trooper suggested in earlier testimony.

"I don't know nothin' about no sock," Banner said.

Prosecutors said before court concluded that they have two witnesses left -- a DEA drug specialist and an FBI chemist -- and that they intend to rest their case on Friday morning.

Defense counsel said they would call two or three witnesses and would likely rest their case by the end of the day on Monday.

As Lowell previously suggested, he may call James Biden, the president's brother, and Naomi Biden, the president's eldest granddaughter.

He also said that no decision has yet been made on whether Hunter Biden will testify in his own defense.

Court then was recessed for the day.
