Prosecutors in Hunter Biden gun trial expected to wrap case today

Prosecutors in Hunter Biden's gun trial are expected to call their last two witnesses Friday, following testimony a day ago from key witness Hallie Biden, who was romantically involved with Hunter Biden and found and disposed of the gun at the center of the case. 

Next, Hunter Biden's attorneys will present their case, which could include putting him on the witness stand. 

The prosecution's last two witnesses Friday morning are expected to be a chemist for the FBI and a DEA agent.
