Hunter Biden’s former mistress is asking a court to jail him for "criminal contempt" in their custody dispute, saying he has flouted the judge’s order to turn over financial information. Biden, who is fighting in an Arkansas circuit court to reduce his child support payments and block his four-year-old daughter from taking the "Biden" last name, is "playing games with discovery" by failing to fully disclose his investment and income records, according to a new court filing from the child’s mother, Lunden Alexis Roberts. Her lawyers say it is a "willful and contemptuous violation" of the court’s orders by Biden, who aims to "disown" the preschooler he fathered with Roberts.
