What to know about Hunter Biden's criminal trialHunter Biden, President Joe Biden's only surviving son, faces three charges tied to the possession of a gun while using narcotics. He has pleaded not guilty. The jury began deliberating yesterday afternoon after prosecutors and the defense finished their closing arguments. Prosecutors argued the evidence against the president's son was "overwhelming" and that they had proved their case. The defense said that the prosecution had not proved their case beyond a reasonable doubt and it was “time to end” the trial. The list of those who were called to testify last week include Hallie Biden, the wife of Hunter Biden's late brother, Beau Biden; Gordon Cleveland, the man who sold Hunter Biden the gun at the heart of the case; and Hunter Biden's daughter Naomi Biden. Hunter Biden did not take the stand.
