• The federal gun law used to indict Hunter Biden has a surprising critic: a conservative-led federal appeals court
• The panel ruled the law was unconstitutional in another case, but legal experts say it could come up in Biden's case.
• The president's son was indicted on three gun-related charges on Thursday after his original plea deal fell apart in court.
