Hallie Biden testifies she "panicked" when she found gun in Hunter Biden's car

Hallie Biden, the widow of Hunter Biden's brother Beau Biden, testified Thursday in Hunter Biden's federal gun trial that she was "panicking" when she found and later discarded the firearm at the center of the case, and she said that it was through Hunter Biden that she also came to use crack cocaine.

Hallie Biden is considered to be the prosecution's star witness, and her appearance on the stand followed Gordon Cleveland, who testified Wednesday that he sold Hunter Biden the firearm. Prosecutors have granted Hallie Biden immunity for her testimony. 

After Hallie Biden, the jury heard testimony from two Delaware police officials and then the man who found the gun in the trash receptacle. At the end of the day Thursday, the defense said it had not yet decided if it would call Hunter Biden to the stand. 

Hallie Biden told the court she found the firearm when she was clearing out his car, which she often searched for drugs and alcohol. Prosecutors introduced parking lot surveillance footage that showed her driving into a grocery store parking lot and throwing the gun away in a dumpster, followed by parking lot video of her that showed her returning to the grocery store to search for the gun.
