Lawyers for Donald Trump and for the U.S. House on Wednesday asked a Washington federal appeals court to expedite its review of a congressional subpoena that seeks financial records from the president’s longtime accounting firm.

The new case in the U.S. Court of Appeals for the D.C. Circuit will mark the first time a federal appeals panel will weigh a House subpoena that demands Trump-related financial information. The president has vowed to resist congressional subpoenas seeking records and testimony from lawyers and other officials in his orbit.
