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.

After a lengthy sidebar, overflow room cameras suddenly turned on to show prosecutors questioning a previous witness, FBI agent Erika Jensen, suggesting that the defense has rested its case and prosecutors are introducing a rebuttal case before the trial moves on to closing arguments.

If so, that would indicate that Hunter Biden did not testify in his own defense.

This morning's proceedings are underway.

Judge Maryellen Noreika began by reviewing with both parties motions by the defense to change proposed jury instructions.

The jury is expected to be brought back into court at 9 a.m. ET.

Defense attorney Abbe Lowell continued to probe Hallie Biden's memory of the period in 2018 when she discovered the gun purchased by then-boyfriend Hunter Biden, at one point remarking that there are "some things you remember and other things you don't."

She testified that for most of the month of October 2018 she did not see Hunter Biden abusing alcohol or drugs.

She also said that in the period after she disposed of the gun and filed a police report, her relationship with Hunter was "more tense."

When her testimony concluded, she stepped off the stand.

The government next called Delaware State Police officer Joshua Marley as its next witness.
