The lower court order compelling Trump’s longtime accounting firm Mazars USA to turn over the president’s financial records will be delayed until the Supreme Court decides whether to take up Trump’s appeal. Trump has requested that the Supreme Court protect his financial records from both House investigators and the Manhattan district attorney’s office, which is conducting a criminal investigation.
