As Hunter Biden's defense case gets underway, two more members of the Biden family have entered the courthouse: Naomi Biden and James Biden.

Naomi Biden is the daughter of Hunter Biden and granddaughter of President Joe Biden.

James Biden is Hunter Biden's uncle and President Biden's brother, who Hunter's attorney told the jury during opening statements paid for some of Hunter Biden's rehab and lived with him briefly afterward.

Defense attorney Abbe Lowell previously suggested both James Biden and and Naomi Biden could take the stand for the defense.

After jurors left the courtroom for a break, defense attorney Abbe Lowell moved for an acquittal for by orally submitting a Rule 29 motion, citing constitutional challenges and an insufficiency of evidence.

Judge Maryellen Noreika indicated her skepticism at the longshot bid with a chortle as Lowell described the legal underpinnings of his motion.

"You're laughing," Lowell said, before joking that her "smile" suggested she was "likely skeptical."

Both Lowell and the judge agreed that one of his claims in particular was an "interesting concept."

Lowell then told the court that the first two witnesses he plans to call for the defense are Ronald Palimere, the owner of the gun shop where Hunter Biden purchased the Colt revolver at the center of the case, and Jason Turner, an employee of the store.

Prosecutors have rested their case against President Joe Biden's son Hunter Biden.

The defense is scheduled to present its case next.

Defense attorneys have said they could possibly wrap up their case by Monday, in which case jurors could begin deliberations as soon as Tuesday or Wednesday.

DEA special agent Joshua Romig took the stand to testify as an expert in the "coded language" used in drug trafficking.

He analyzed the language used in some of Hunter Biden's text messages, some of which appeared to be drug transactions.

First lady Jill Biden, back in the courtroom this morning, looked on as Romig testified.

Special counsel David Weiss, who brought the case against Hunter Biden, is also in court today.

Attorneys for Hunter Biden, in their cross-examination of FBI Special Agent Erika Jensen, attempted to push back on prosecutors' contention that Hunter Biden was abusing drugs at the time he said on a gun-purchase form that he was drug-free.

A key piece of evidence comes from Hunter Biden's 2021 memoir, in which he described his "relapse" just weeks after leaving rehab in August -- just six weeks before purchasing the firearm.

"I stayed clean for two weeks then relapsed," Hunter Biden wrote in his book.

Defense attorney Abbe Lowell, on cross-examination, questioned the assumption that Hunter Biden's relapse implied that he was referring to his drug use -- suggesting instead that he was referring to his alcohol addiction.

"When he was referring to that in his book, was he talking about relapsing to drugs and alcohol, or do you know what he meant?" Lowell asked.

"I can only state what was stated," Jensen said.

"Which is, 'Then I relapsed?'" Lowell asked.

"Just what it says, 'I relapsed,'" Jensen replied.

Jensen also acknowledged that she could not verify that Hunter Biden was continuously using drugs from 2015 to 2019, saying, "My recollection is that there are excerpts where he was principally occupied with smoking crack cocaine. I didn't get the sense that it was the entire history."

"Meaning that there were periods of time that he was not?" Lowell asked.

"I think there -- including the period in August where we have some invoices for rehab, that there were periods where there was not," Jensen said.

It was an important moment for the defense, as Lowell managed to establish that Hunter Biden's use of drugs was not consistent -- cuing up his argument that the president's son was not on drugs at the time of his firearm purchase.

Prosecutors also entered into evidence records related to enormous cash withdrawals Hunter Biden made -- more than $150,000 from September through November of 2018, including a $5,000 withdrawal on the day he purchased the gun. Prosecutors suggested this cash was used to procure drugs; Lowell, on cross-examination, established that Hunter Biden paid $900 in cash for the weapon and accessories.

Court was subsequently recessed for the day, with Lowell's cross-examination of Jensen scheduled to resume Wednesday morning.

Prosecutors suggested that Hallie Biden would be the next witness after Jensen, making it likely that the first Biden family member to testify will take the stand at some point tomorrow.
