Trump attorney vows to go to Supreme Court in tax return case after appeals court allows subpoena

President Trump's attorney is vowing to go to the Supreme Court after a federal appeals court ruled Monday to allow New York City prosecutors to proceed with a subpoena for records including the president's tax returns.

Trump was attempting to block a subpoena which was issued to accounting firm Mazars USA by the Manhattan District Attorney’s Office. In a 34-page ruling handed down Monday morning, the 2nd Circuit Court of Appeals affirmed a district court's ruling that state prosecutors can subpoena the tax returns of a sitting president.
