A New York appellate court on Wednesday heard arguments in Donald Trump’s bid to undo his 2024 felony conviction in the Stormy Daniels hush-money case, focusing on two issues with implications well beyond this prosecution: how presidential-immunity principles apply in a state criminal case, and whether prosecutors properly relied on another alleged crime to elevate misdemeanor falsified-records charges into felonies.

Trump’s lawyers argued that the conviction was tainted by the use of evidence tied to official presidential conduct, while Manhattan prosecutors contended the case centered on private acts and business records, not protected executive decision-making.
