Hunter Biden’s daughter Naomi testified Friday in his federal gun trial about visiting her father while he was at a California rehab center, telling jurors that he seemed to be improving in the weeks before he bought the revolver in 2018.

“I hadn’t seen my dad in a long time, and I knew he was in a rehab facility there. He reached out,” she told jurors softly, explaining that they met at a coffee shop, along with his “sober coach.” As she was dismissed from the stand, she paused to hug her dad before leaving the courtroom.

The defense began calling witnesses shortly after federal prosecutors wrapped up their case. Hunter Biden’s attorney Abbe Lowell started by calling another gun store clerk who was there when the gun was purchased, raising questions about what he saw as inconsistencies on the form.

He also questioned the owner of the shop who allowed the sale to go through using Hunter’s passport, though it did not include an address as required.

Then he called Hunter’s daughter. In October 2018, the month Hunter Biden bought the gun, Naomi traveled from Washington to New York in her father’s truck to move her boyfriend’s belongings. Hunter drove Joe Biden’s Cadillac to New York later that month to retrieve his truck, leaving the Cadillac with Naomi. She told jurors she didn’t see any drug paraphernalia or evidence of drug use.

“He seemed great. He seemed hopeful,” she said.

But prosecutors showed Naomi texts where he didn’t respond to her for hours after she messaged him about switching cars. At 2 a.m., Hunter texted Naomi asking where the keys to his truck were and whether her boyfriend could meet and swap vehicles.

“Right now?” she responded.

“Do you know what your father was doing at two o’clock in the morning and why he was asking you for the car then?” prosecutor Leo Wise asked.

“No,” she said.

Wise read out to her a text message from the time, where she responded: “I’m really sorry dad I can’t take this.”

When court broke for lunch, and as Hunter Biden prepared to leave, he motioned to the first row that was full of his family members, including first lady Jill Biden, who traveled back from France for the proceedings. The first lady took Hunter’s hand and held it until they got to the door.

Jurors were sent home for the afternoon after the defense had no more witnesses, and Lowell said he was weighing who else to call, though previously he said the president’s brother James would take the stand, and he was in court. The trial will resume Monday.

The week’s proceedings have been largely dedicated to highlighting the seriousness of Hunter Biden’s drug problem through highly personal testimony, all in an effort by prosecutors to prove that the president’s son lied on a mandatory gun-purchase form when he said he was not illegally using or addicted to drugs.

Jurors heard earlier in the week from Hunter Biden’s ex-wife and a former girlfriend who testified about his habitual crack use and their failed efforts to help him get clean. They saw images of the president’s son bare-chested and disheveled in a filthy room, and half-naked holding crack pipes. And they watched video of his crack cocaine weighed on a scale.

Prosecutors say the evidence is necessary to prove that Hunter, 54, was in the throes of addiction when he bought the gun and therefore lied when he checked “no” on the form that asked whether he was “an unlawful user of, or addicted to” drugs.
