Can a state attorney request documents from a subpoena to a president?

The United States Supreme Court rejected Trump's appeal not to show his taxes. The judges ruled that the president cannot block the financial information claimed by Manhattan district attorneys. Rafael Cox Alomar, a professor at the University of the District of Columbia, explained that, for the first time, the Supreme Court decides that a state attorney has the authority to request this information "from the most powerful man in the United States."
