President Biden has issued a sweeping pardon to his only surviving son, Hunter, despite having previously promised not to. The president attributed his decision to issue the pardon — which absolves the younger Mr. Biden of responsibility for both firearm and tax crimes, in addition to any other federal crimes he may have committed between January 1,  2014 and December 1, 2024 — to his conviction that his son, and by extension himself, were victims of a weaponized justice system.
