Judge Maryellen Noreika, in her initial instructions to jurors, explained how they are to apply the law to the facts of the case for the three criminal counts Hunter Biden faces.

"You must not attach any significance to the fact that the defendant did not testify," she read aloud in the courtroom, after the defense decided not to call Hunter Biden to the stand.

The judge defined "knowingly," the central term by which jurors must determine if Hunter Biden bought the gun at the center of the case "knowing" he was an addict or user of drugs, after he stated on the gun-purchase form that he was not.

Closing arguments are scheduled to begin at 12:05 p.m. ET, after which the judge will give the jury her final instructions and their deliberations will begin.

Closing arguments will begin at about noon ET after Hunter Biden chose not to testify in his federal gun case.

The defense rested without him taking the stand, after which prosecutors presented a brief rebuttal case, then the judge gave the jury their initial instructions.

Following the prosecution's rebuttal case, the judge read the jury their initial instructions.

Court is then expected to break for lunch, with closing arguments currently scheduled for the afternoon.

The judge will then give the jury their final instructions before they begin deliberations.

The government rested its rebuttal case after a brief cross-examination of FBI special agent Erika Jensen, who testified about location and text message data relevant to the case.

Attorneys then gathered for another sidebar conference.

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.
