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.

In dramatic testimony, Hunter Biden's former romantic partner Hallie Biden described how, on the morning of Oct. 23, 2018, she went to go "clean out" Hunter Biden's car and found a gun.

"What did you find, in addition to trash and clothes?" prosecutor Leo Wise asked her.

"Remnants of crack cocaine and some paraphernalia," Hallie recounted. "Oh and the gun, obviously."

Hallie Biden said she found the firearm in "the arm console" of the car, which she said was not locked because "the lock had been broken." She said it was the first time she had ever seen a gun. She also found ammunition.

"I panicked, I wanted to get rid of them," she told the jury.

Asked why she panicked, Hallie Biden said she "didn't want him to hurt himself." She said she also worried about her kids finding the gun, saying she considered "hiding" it somewhere but was worried they would find it.

She said those frantic moments led to her throwing the gun in the trash. She told the jury she found a pouch to put it in -- which authorities say later tested positive for having cocaine on it -- and put the gun inside. The jurors were then shown the brown pouch she used.

"I was afraid to kind of touch it, I didn't know if it was loaded," Hallie Biden said, telling jurors she then put the pouch into another bag.

"I took it to the grocery store up the road and I threw it away," she testified.

At this point, jurors were shown surveillance video from the grocery store showing Hallie Biden throwing the gun into the trash.

In the video, her car is seen pulling into the parking lot; she then gets out of the driver's seated, opens the back door to get out the gun, then walks over to the store and places the bag in a garbage receptacle.

"Is that you Mrs. Biden?" prosecutor Leo Wise asked about her image on the video. "Yes," she replied.

Hunter Biden, sitting at the defense table, appeared to be locked on Hallie Biden the entire time, his head resting in his hand. He periodically covered his mouth.
