Hunter Biden, in court today, affirmed his decision not to testify in his own defense, telling the judge "I do" when she asked him if he understood it was his own decision to make, according to the transcript of the proceedings released after court was dismissed for the day.

"Did you make a decision not to testify voluntarily?" Judge Maryellen Noreika asked him, according to the transcript.

"I did," he said.

The questioning from Noreika occurred during a sidebar with Hunter Biden, his attorneys, and prosecutors that was conducted out of earshot of reporters but released as part of the transcript.

"You understand you have the right to testify in your own defense?" the judge asked Hunter Biden, per the transcript.

"I do," he said.

"If you don't testify, you understand your decision not to testify cannot be held against you and I will instruct the jury to that effect?" she asked.

"Agreed," he responded.

"It's your decision and yours alone to make, do you understand that?" the judge asked.

"I do," he responded.

"It's not your attorney's decision, it's not the government's decision, it's not my decision, you understand all that?" she asked.

"I do," he said.

The jurors in Hunter Biden's federal gun trial have been dismissed for the day, after deliberating for one hour with no verdict.

Hunter Biden left the courthouse after the jury was dismissed.

The jurors will be back tomorrow at 9 a.m. ET to resume their deliberations.

The jury has begun deliberations on the three felony counts Hunter Biden faces in his federal gun case.

Prior to the jury getting the case, the government rebutted defense attorney Abbe Lowell's closing argument by asserting again that Hunter Biden was a drug addict when he bought the gun at the center of the case and that he knew it -- beyond a reasonable doubt.

There are "seven ways to Sunday" to show Hunter Biden was an addict and it was "preposterous" that he -- a "Yale-educated lawyer" -- didn't know he was buying a gun while knowingly addicted, prosecutor Derek Hines argued.

Hines rebutted Lowell's characterization of the government's treatment of Hunter Biden's daughter Naomi Biden as "cruel."

Naomi Biden was "completely uncomfortable" because "she couldn't vouch for the defendant's sobriety," Hines argued.

Hines closed by saying that if the jury doesn't determine Hunter Biden is a crack addict based on the evidence in the case, "then no one is a crack addict of unlawful use."

Judge Maryellen Noreika then delivered the final portion of her instructions and sent jurors to begin their deliberations.

The judge indicated that she would not keep jurors past 4:30 or 4:45 p.m. ET today.

Defense attorney Abbe Lowell, in his closing argument, urged jurors to dispense with the government's "conjecture and suspicion" and find his client not guilty on all three counts.

"We have had Hunter's life in our hands" until now, Lowell said, referring to his legal team. "And now we have to give it to you."

Lowell repeatedly referred to prosecutors' case as a "magicians' trick" -- to "watch this hand and pay no attention to that one," as he said -- arguing that prosecutors failed to "fill in the gaps" about Hunter Biden's drug use around the time of his firearm purchase "because they don't have the proof."

Lowell also referred to prosecutors' strategy of showing Hunter Biden's pattern of drug use as an "accordion," meant to "compress" the timeline and make it seem to jurors that he was actively using drugs in October 2018, when he said on a government form that he was not addicted to drugs in order to purchase a Colt handgun.

The defense attorney also attacked some of the tactics prosecutors used, calling their treatment of Hunter Biden's daughter Naomi Biden "extraordinarily cruel" and saying that many of their questions and evidence were introduced with the intention of "embarrassing Hunter."

He also asked jurors to recall gaps in the recollections of Hunter Biden's then-girlfriend Hallie Biden, and suggested they should remember the immunity agreement she struck with prosecutors for her testimony.

"These are serious charges that will change Hunter's life," he said of the three felony charges the president's son faces, adding that "it's time to end this case."

Following Lowell's closing, the government was scheduled to have a short rebuttal, at which point the judge was to finish her jury instructions before the jury gets the case.

In the first exhibits presented in the government's case, prosecutors played excerpts from the audiobook of Hunter Biden's 2021 memoir "Beautiful Things" -- in which jurors heard in his own words about some of the most personal low points of his yearslong addiction to crack cocaine.

FBI Special Agent Erika Jensen, the government's first witness, introduced about a dozen audio excerpts played out over an hour, as Hunter Biden's voice boomed over the courtroom's loudspeakers while his stepmother, first lady Jill Biden, and several other members of his family sat in attendance.

"I used my superpower of finding crack cocaine anytime, anywhere," Hunter Biden said of the year 2018 -- the same year he purchased the gun that prosecutors say he lied to get. The audio contained passages in which he spoke about the darkest and most dangerous moments of his addiction -- at one point doing cocaine in the bathroom while on a graduation trip with his daughter. .

Jill Biden and her daughter Ashley Biden sat shoulder-to-shoulder as the clips played out, at times leaning their heads against one another. At one point, as Hunter Biden's voice was heard describing a raucous 12-day bender in Los Angeles, Jill Biden lifted her left arm and draped it around Ashley's shoulders.

A person sitting with the family told ABC News they were both "fighting off tears."

Hunter Biden, for the most part, stared intently into the nearby monitor displaying the book's contents, at one point slightly nodding along as he reheard some of his most painful struggles. The jurors appeared largely engaged, with many taking notes and looking up at the screen to follow along.
