The House of Representatives on Wednesday asked the U.S. Court of Appeals for the D.C. Circuit for an "immediate issuance of the mandate" in getting President Donald Trump's private accounting firm Mazars to provide documents to Congress.

House lawyers argued in the filing that the court should move to allow immediate enforcement "to ensure timely compliance with the Committee's valid subpoena, which was issued to further urgent investigations and inform critical legislative judgments."

And they said the circuit court's 2-1 ruling last week upholding the subpoena "provides no basis for rehearing."

In an opinion issued last Friday, Judge David Tatel wrote for the majority that the House Oversight Committee's subpoena seeking Trump's private financial records from Mazars fell within Congress' oversight duties and could be enforced.

The House's filing Wednesday also invoked impeachment for the first time in relation to the subpoena.

"The House is now engaged in an impeachment investigation against President Trump, which is advancing on an expedited basis, and information received in response to the Mazars subpoena could be highly relevant to that inquiry as well," the filing states. "Rather than leave Congress with its 'oversight function informationally crippled' just 'when oversight and legislation are most urgent,' this Court should respect the Committee's need for these documents and direct immediate issuance of the mandate."

Attorneys from the firm Robbins, Russell, Englert, Orseck, Untereiner & Sauber were also listed on the brief, the first time the firm has appeared in the case. Law firm partners Roy Englert, Jennifer Windom and Alan Strasser filed their notice of appearance shortly after the House's request was filed.

The House said that, if the court did not immediately issue the mandate, "it should shorten the plaintiffs' time to petition for rehearing or rehearing en banc to seven days from the date of the Court's ruling on this motion."

That could help speed up the process of getting the case to the Supreme Court, the apparent goal of Trump's private attorneys at Consovoy McCarthy.

The Mazars case is one of several involving Trump's private financial records making their way through the courts. A ruling from the U.S. Court of Appeals for the Second Circuit is expected to be issued shortly on a similar subpoena seeking documents from Deutsche Bank and Capital One.
