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.

Hunter Biden has arrived at the courthouse for Day 6 of his federal gun trial, accompanied by his wife Melissa Cohen Biden.

First lady Jill Biden arrived shortly afterward.

President Joe Biden's brother James Biden and sister Valerie Biden also arrived.

The two waited outside until the court opened at 8 a.m. ET.

As the second week of Hunter Biden's gun trial gets underway this morning, defense attorneys will confront their most consequential decision: whether to put their client on the witness stand.

To allow Hunter Biden to testify in his own defense would carry myriad risks, as the president's son would likely face a grueling cross-examination from a prosecution team that has shows itself adept at eliciting testimony supporting their central contention in the case -- that Hunter Biden was addicted to drugs at the time he purchased the handgun at heart of the case.

Jurors witnessed that on Friday, when Naomi Biden, the 30-year-old daughter of Hunter Biden, struggled to explain text messages she sent her father in October 2018 after he had purchased the gun -- in which she seemed to express concern about his addiction, despite testifying moments earlier about how "great" her father seemed at the time.

If Hunter Biden decides not to take the stand, jurors could possibly have the case by the end of the day, after closing arguments and jury instructions.

Court is scheduled to get underway earlier than usual today, at 8:15 a.m. E.T.

Judge Maryellen Noreika has so far quizzed more than 50 Delaware residents about their fitness to serve as jurors in the first trial of a sitting president's son. And being Delaware -- a small state that Joe Biden represented in the Senate for more than three decades -- nearly all of them had some level of familiarity with Hunter Biden's legal travails.

"I live in Delaware," one prospective juror said. "You can't swing a cat without hearing something."

"Delaware is a small place," another said. "So you hear stuff."

Several jurors said they had heard or read about this trial specifically. Most had only a cursory understanding of the case, but others expressed a detailed accounting of the charges. A few jurors mentioned the ill-fated plea deal that Hunter Biden initially struck with prosecutors last summer.

"At one time there was a deal, and then there wasn't," one man said.

One woman had even read Hunter Biden's memoir, "Beautiful Things," which prosecutors plan to use to help prove their case. She was excused by the judge.

President Joe Biden has emerged repeatedly in questioning, with prospective jurors expressing both positive and negative feelings on his presidency. One woman said she believed that Hunter Biden was facing charges largely because his father is the president.

"I think it was a very strong factor," she said.

Several others have been dismissed for harboring negative views toward the Bidens. Asked for his opinion about the president, one man said, "Not a good one." Another man said, "Negative toward the defendant." Both were excused.

The jury questionnaire also includes several questions about drug and alcohol addiction -- an affliction that many prospective jurors said has personally affected them.

One woman held back tears as she described how her best friend had died of a heroine overdose. Another man said his daughter is a recovering addict.

"Everybody needs a second chance," he said.

Judge Noreika has been pressing ahead, intent on getting a jury seated as soon as possible -- perhaps even by the end of the day.

In addition first lady Jill Biden and Hunter Biden's wife Melissa, his half-sister Ashley Biden attended court during the morning session, and his confidant and financier Kevin Morris is also in attendance.
