Washington (CNN) President Donald Trump on Friday lost his appeal to stop a House subpoena of his tax documents from his longtime accountant Mazars USA.

In a 2-1 ruling, the US Court of Appeals for the District of Columbia Circuit upheld a lower court ruling saying the firm must turn over eight years of accounting records.

The court specifically weighed in on this idea, writing it has "no authority" to require the House to take a full vote in support of a subpoena to investigate the President, citing the Constitution.

"The courts lack the power to invalidate a duly authorized congressional subpoena merely because it might have been 'better [if]...the full House' had specifically authorized or issued it," the court wrote. "Unless and until Congress adopts a rule that offends the Constitution, the courts get no vote in how each chamber chooses to run its internal affairs."
