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.

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.

Lowell has argued Hunter did not think of himself as an “addict” when he bought the gun and did not intend to deceive anyone.

Meanwhile, President Joe Biden worked to walk the line between president and father, telling ABC in an interview that he would accept the jury’s verdict and ruling out a pardon for his son. Earlier this week, he issued a statement saying: “I am the President, but I am also a Dad. Jill and I love our son, and we are so proud of the man he is today.”

Biden is in France this week for D-Day anniversary events. Jill Biden, who attended court most of the week, will return to France for a state dinner. Hunter Biden has been charged with three felonies: lying to a federally licensed gun dealer, making a false claim on the application by saying he was not a drug user and illegally having the gun for 11 days.

He has pleaded not guilty. He had hoped to resolve the gun case and another separate tax case in California with a plea deal last year, the result of a yearslong investigation into his business dealings. The deal had him pleading guilty to lower-level charges that would have avoided the spectacle of a trial so close to the 2024 election. It fell apart after Judge Maryellen Noreika, who was appointed by Donald Trump, questioned unusual aspects of the proposed agreement, and the lawyers couldn’t resolve them.

Hunter Biden said he got charged because the Justice Department bowed to pressure from Republicans who argued the Democratic president’s son was getting special treatment, and who have escalated their attacks on the criminal justice system since Donald Trump’s recent conviction in New York City in a hush money case.
