Jay Sekulow, an attorney for Trump, told Reuters that the president would appeal the ruling and seek to delay enforcement of the subpoena.
The subpoena is related to an investigation by Manhattan District Attorney Cyrus Vance. In a court filing last month, Vance said his analysis was tied into"alleged insurance and bank fraud by the Trump Organization and its officers," among other things.
Trump, who's campaigning for re-election at November, has fought efforts by lawmakers and prosecutors to receive his tax records, which should shed light on his financial dealings.
