President Biden's son, Hunter, has been criminally charged with three counts of lying when buying a firearm, after a proposed plea deal collapsed. This is the first time the child of a sitting president has been criminally prosecuted. All three counts relate to Mr Biden allegedly lying on forms while buying a firearm when he was a drug user. If convicted, he faces a maximum penalty of 25 years in prison, the justice department said in a statement. The younger Mr Biden's legal woes have become a political lightning rod as his father seeks re-election. Earlier this week, Republicans in the House of Representatives announced an impeachment inquiry into President Biden: among the accusations being levelled against him are that he lied about his involvement in his son's business dealings while serving as vice-president. Two Internal Revenue Service investigators have also claimed that the justice department stymied their investigation into Hunter Biden's tax return.
