Hunter Biden's defense team called his daughter Naomi Biden to testify that she visited him in rehab in 2018, and he seemed "hopeful," countering that he was using drugs in October 2018. Hunter Biden's ex-sister-in-law, Hallie Biden, testified that she found the gun in his truck in 2018 and disposed of it because she was worried he or her kids would hurt themselves with it. Hunter Biden is on trial for charges related to illegally purchasing a firearm while using illicit drugs like crack cocaine in 2018. Prosecutors rested their case after arguing that evidence shows Hunter Biden was addicted to crack at the time he bought the gun and lied about it on background check forms.
