The fight over a congressional subpoena to President Donald Trump's longtime accounting firm Mazars USA LLP is being appealed to the federal appeals court in Washington, D.C.

Attorneys for President Donald Trump and his businesses on Tuesday morning filed a notice of appeal to federal trial court Judge Amit Mehta, after the judge upheld a U.S. House Oversight Committee subpoena which sought Trump's financial records dating back to 2011.

A quick appeal to the U.S. Court of Appeals for the D.C. Circuit was expected. Mehta declined on Monday to put his ruling on hold pending any appeal from Trump. The D.C. Circuit could put the subpoena on hold while they consider the appeal.

The House oversight panel had previously agreed to give Mazars seven days following a court ruling to produce the records.

Consovoy McCarthy partners William Consovoy and Patrick Strawbridge represent the president in his personal capacity; Michael Best & Friedrich partner Stefan Passantino, a former Deputy White House counsel, represents the Trump organization and other Trump-related business entities which are also involved in the lawsuit.

U.S. House general counsel Douglas Letter represented members of Congress in the suit.

This is a developing story.
