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.

Prosecutor Leo Wise read through text messages Hunter Biden's then-girlfriend Hallie Biden exchanged with him in the days following his gun purchase and on the day that she discovered and discarded it, asking her on the stand to provide context for their communications.

Within days of buying the gun, Hunter Biden texted her that he was about to meet a drug dealer named "Mookie." Hallie Biden testified that she thought that to mean "that he was buying crack cocaine."

In another message, Hunter Biden wrote that he was "buy" and then seconds later added "ing." Asked how she interpreted that message, Hallie Biden said, "I mean, I would guess but I didn't know for sure."

In the messages, Hallie Biden repeatedly expressed concern for him, at one point saying explicitly that she didn't want him to die. Wise asked her if she was worried that he would overdose on drugs.

She said "Yes," but added that she was also worried he might die by "suicide, I didn't know."

Wise then asked her to describe the messages the two exchanged on the morning she threw the gun away.

"It's hard to believe anyone is that stupid," Hunter Biden wrote to her.

"He was angry with me" for discarding his gun and putting him in legal jeopardy, Hallie Biden told jurors.

"I'm a liar and a thief and a blamer and a user and I'm delusional and an addict," Hunter Biden texted her.

She texted back, "Let's do this right," and suggested "working on sobriety" together.

Asked what she meant by "sobriety" -- alcohol or drugs or both -- Hallie Biden replied, "Well, if you're sober, it's all of the above."
