(CNN) House Oversight Chairman Elijah Cummings said Wednesday that an accounting firm that provided financial statements for President Donald Trump will give financial documents to his committee — but only if they receive a subpoena first.

Cummings had set a Wednesday deadline for the accounting firm, Mazars USA, to provide financial documents from Trump going back 10 years as part of the committee's probe into Trump's finances.

"The accounting firm told us that they will respond, and they just want a subpoena," the Maryland Democrat told reporters Wednesday. "They have told us that they will provide the information pretty much when they have a subpoena. And we'll get them a subpoena."

Cummings described it as a "friendly subpoena" to the firm because it had been requested.

Michael Cohen, the President's former lawyer and fixer who accused Trump of financial fraud, provided the committee with three years' worth of financial statements prepared by Mazars, in which Cohen says Trump inflated his wealth as he attempted to purchase the National Football League's Buffalo Bills.
