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.

Prosecutors have introduced Hunter Biden's infamous laptop as evidence while questioning FBI agent Erika Jensen, their first witness.

Prosecutors asked Jensen about email messages found on the laptop and in Hunter Biden's iCloud account that appear to be about his drug use in 2018.

The government had said in pretrial court filings that it was planning to introduce materials on the laptop as evidence in the case.

The laptop has become a symbol of the legal and political controversy surrounding the president's son in recent years. Attorneys for Hunter Biden had previously attempted to preclude the laptop as evidence in the trial, arguing that they have "numerous reasons to believe the data had been altered and compromised before investigators obtained the electronic material."

But special counsel David Weiss argued in court filings that attorneys for Hunter Biden had not "provided any evidence or information that shows that his laptop contains false information," and the judge agreed to admit it as evidence.

Data from the laptop was purportedly obtained and later disseminated in 2019 by a Wilmington, Delaware, computer repairman after the laptop had been dropped off at his shop for repair.

With that context in mind, prosecutors did not rely on the laptop on its own; investigators said they cross-referenced every email, WhatsApp message, iMessage, and text message with Apple Inc. to establish the credibility of the data.

"Ultimately, in examining that laptop, were investigators able to confirm that it was Hunter Biden's laptop?" prosecutor Derek Hines asked Jensen.

"Yes," Jensen said.

"How?" Hines asked.

"Among other things, there was a serial number that's on the back of this laptop that matches the Apple subpoena records that they obtained in 2019, so it matches the registration of this particular device to the iCloud account at a particular date," Jensen said.

"So from the data from the laptop and the hard drive, did you -- what did you do next, or what did the FBI do next when assessing the addiction evidence?" Hines asked.

"So from the data that was extracted from both the iCloud back ups and this -- the laptop, investigators were able to go through largely WhatsApp messages, iMessages, and text messages, and found evidence of addiction within the messages," Jensen said.

Prosecutors also showed jurors an invoice for $85 from the computer repair shop where Hunter Biden dropped off the laptop for repair, which had been sent to an email address belonging to Hunter Biden.

"You said Apple Inc. provided that ... from the iCloud?" Hines asked.

"Yes," Jensen said.
