Key Witnesses Testify in Hunter Biden Gun Trial

Jurors in Hunter Biden's criminal trial heard testimony from the gun store clerk who sold him the firearm at the center of the case. Prosecutors argue Biden lied about his drug use on the purchase form, while the defense suggests he did not believe he had an active drug problem at the time. Key witnesses, including Biden's ex-wife and a former girlfriend, testified about his drug use. The trial follows the collapse of a plea deal and occurs amid political scrutiny and a separate tax case against Biden.
