Hallie Biden, Hunter Biden's former romantic partner who is the widow of his brother Beau Biden, has taken the stand as the prosecution's next witness.

Prosecutors have said they expect her to testify about Hunter Biden's drug at the time of his gun purchase in October 2018.

Before gun store clerk Gordon Cleveland stepped off the stand, he testified that Hunter Biden did not exhibit any symptoms of drug or alcohol abuse when he purchased the gun at the center of the case.

When asked by defense attorney Abbe Lowell if Hunter Biden exhibited any symptoms at the time of his gun purchase, such as being "glassy eyed" or smelling of alcohol, Cleveland replied, "None at all."

Cross-examining gun store clerk Gordon Cleveland, defense attorney Abbe Lowell asked about the framing of the various questions on the gun form that Hunter Biden is accused of lying on -- including the difference between "have you" and "are you."

The form, for example, asks the applicant if they "have ever" been convicted -- but asks "are you" an unlawful user of drugs.

The defense team has used this to argue that Hunter Biden could have reasonably believed he was not violating any laws when he checked "No" on the drug-use box, because they say he was not currently using drugs.

"It does not say, 'Have you ever,"' Lowell said.

In court today, Hunter Biden has been attentive and focused, watching as attorneys clashed earlier over evidence. He gripped his pen as prosecutor Leo Wise asked the judge to keep out texts that his team wishes to use when they cross-examination Hallie Biden.

Special counsel David Weiss, who brought the case, has been seated in the front row behind his prosecution team, periodically nodding along as they make their arguments.

Gordon Cleveland, the gun store clerk who sold Hunter Biden the firearm at the center of the case, returned to the stand.

Cleveland was being cross-examined by the defense after testifying for the prosecution yesterday.

Hallie Biden, Hunter Biden's former romantic partner who is the widow of his brother Beau Biden, is expected to be the next witness following Cleveland.

Court resumed this morning with a sidebar conference.

Prosecutors and defense attorneys were arguing before the judge about an exhibit the defense wants to introduce when Hallie Biden, Hunter Biden's former romantic partner, takes the stand as expected later today.

Separately, defense attorney Abbe Lowell signaled his intention to file a motion to have the case thrown out after the government rests.

The long-shot bid will be filed on grounds of constitutional shortcomings and insufficient evidence, Lowell said.

Lowell also said his witnesses -- which could include President Joe Biden's brother James Biden and Hunter Biden's daughter Naomi Biden -- may not be available until Friday morning.

The day's final witness was Ed Banner, the 80-year-old Navy veteran who recovered Hunter Biden's firearm from the trash receptacle outside a supermarket after Hunter Biden's then-girlfriend Hallie Biden had disposed of it there.

Banner described finding the firearm and other items as he was rummaging for recyclables that he would often drive to New York to return for money.

Defense attorney Abbe Lowell had previously suggested that cocaine residue discovered on a leather pouch that held the gun could have been tampered with between the time the firearm was discarded on Oct. 23, 2018, and when it was tested in a lab in late 2023.

"This may sound like an unusual question, but does anyone in your household use cocaine?" Derek Hines asked Banner.

"No," Banner said, appearing somewhat surprised by the question.

Banner also denied wrapping the firearm in a sock, as a Delaware state trooper suggested in earlier testimony.

"I don't know nothin' about no sock," Banner said.

Prosecutors said before court concluded that they have two witnesses left -- a DEA drug specialist and an FBI chemist -- and that they intend to rest their case on Friday morning.

Defense counsel said they would call two or three witnesses and would likely rest their case by the end of the day on Monday.

As Lowell previously suggested, he may call James Biden, the president's brother, and Naomi Biden, the president's eldest granddaughter.

He also said that no decision has yet been made on whether Hunter Biden will testify in his own defense.

Court then was recessed for the day.
