Former U.S. President Joe Biden's prostate cancer has spread to other parts of his body and is causing him pain, his son Hunter said in an interview.
President Biden issued a pardon for Hunter Biden, saying his son was "selectively, and unfairly, prosecuted" because of politics in his gun and tax convictions.
Biden faces a maximum sentence of 17 years in prison and a fine of as much as $1.35 million.
Hunter Biden, 54, pleaded not guilty and says he belatedly paid all of his tax debts after regaining his sobriety in 2019, amid a lifelong struggle with alcoholism and drug abuse.
U.S. District Judge Mark Scarsi, in denying the motion, cited Hunter Biden's previous ill-fated efforts to dismiss the case.
Hunter Biden attempted to enlist support from the U.S. Ambassador to Italy in 2016 to arrange a business meeting on behalf of Burisma for a prospective energy deal, according to his attorney.
