The Republican president is challenging a decision by the New York-based 2nd US Circuit Court of Appeals upholding the verdict. The case that led to the $83.3-million verdict involved comments Trump made while still in office, raising complex questions about presidential immunity. The court said Trump had failed to raise the immunity defense early on in the litigation, thus forfeiting it. Trump's lawyers said the 2nd Circuit "engaged in procedural contortions to avoid addressing presidential immunity." They urged the Supreme Court to also decide that Trump has immunity in the case, calling the question "straightforward."
