Hunter Biden, son of US President Joe Biden, is set to plead not guilty in federal court in Delaware regarding charges related to the illegal possession of a handgun. The charges, stemming from the 2018 purchase of a .38-caliber Colt Cobra revolver, include two counts of making false statements on gun purchase forms. The third charge alleges illegal possession of the firearm. Despite a failed plea deal in July, which sought to exchange the gun charges for guilty pleas on two tax charges, Hunter Biden’s lawyer confirmed the not guilty plea. The case adds legal challenges to the scrutiny of Biden’s business dealings in Ukraine and China.
