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.

In an unexpected move, court recessed for the day following the lunch break, with the defense telling the judge they are "down to that last decision" -- suggesting that they will determine over the weekend if Hunter Biden takes the stand Monday in his own defense.

Defense attorney Abbe Lowell told the court the defense decided not to call one of its expert witnesses.

It also appears defense attorneys reversed course on testimony from Hunter Biden's uncle James Biden, who was already at the courthouse and who Lowell had earlier indicated would be testifying. James Biden was subsequently seen leaving the building.

Prosecutors said they are "still considering" whether they will put on a rebuttal case after the defense rests.

Judge Maryellen Noreika dismissed the jury, telling them to "enjoy a long weekend."

"We are starting to wrap the evidence in this case," she said.

The parties are scheduled to be back in court Monday at 8:15 a.m. ET.
