President Donald Trump’s apparent “disdain” for the investigations being led by congressional Democrats is no reason to block a subpoena seeking records from the president’s longtime accounting firm Mazars USA, lawyers for the U.S. House Oversight Committee told a federal appeals court Monday.

The U.S. Court of Appeals for the D.C. Circuit is weighing Trump’s challenge to a subpoena that targets records that “may provide additional information on whether the president misstated his assets and liabilities on his financial statements,” the House lawyers said in their court filing. A federal trial judge in Washington earlier upheld the subpoena.
