The prosecution has rested its case against the US president’s son, Hunter Biden, who is accused of lying on a federal gun-purchase form when he said he was not using drugs at the time he bought a revolver in 2018.

Prosecutors say Hunter Biden was actively using drugs and purposefully lied on the form.

They called his ex-wife and a former girlfriend to testify that his drug use was habitual.

His brother’s widow, Hallie Biden, also testified about how she found the unloaded gun in his truck, wrapped it in a bag and tossed it in dustbin at a nearby market.

Police later found it.

He has pleaded not guilty.

Defence lawyer Abbe Lowell has said Hunter Biden did not believe he had a serious drug problem at the time of the purchase and that there was no attempt to deceive anyone.

The defence may now choose to call witnesses.
