Hunter Biden’s ex-girlfriend has told a jury he was abusing crack cocaine “every 20 minutes or so” when they first met.
The US president’s son is on trial in Wilmington, Delaware, on charges related to his possession of a firearm while allegedly using narcotics.
Zoe Kestan, who met Mr Biden, 54, during a “private dance” at a “gentleman’s club” in New York, told the court he was often withdrawing cash for drug deals.
It is the first criminal trial for the son of a sitting US president.
He is accused of knowingly lying on federal paperwork when he said he was not a drug user in order to buy a revolver and ammunition from a Wilmington gun shop on 12 October 2018, as well as illegally having the gun for 11 days.
