(CNN) House Oversight Chairman Elijah Cummings said Friday he will issue what he has previously called a "friendly subpoena" to the accounting firm that prepared several years' worth of President Donald Trump's financial statements.

The accounting firm, Mazars USA , had requested such a subpoena from the committee before providing records, and Cummings wrote to committee members he would serve it on Monday.

Cummings had requested financial information from Mazars USA dating back 10 years after Trump's former personal attorney Michael Cohen accused Trump of inflating his net worth in an attempt to buy the Buffalo Bills football team. Cohen provided the committee with Trump's financial statements from 2011, 2012 and 2013 that were prepared by Mazars USA.

"Counsel to Mazars sent a response letter explaining that, pursuant, to the company's legal obligations, Mazars cannot voluntarily turn over the documents 'unless disclosure is made pursuant to, among other things, a congressional subpoena," Cummings wrote in his memo to committee members.

Cummings and other Democratic committee chairman have been seeking Trump's financial information as part of a plethora of probes into the President and his businesses. Cummings and two other committee chairmen have also requested financial information related to the Trump International Hotel from Capital One, which also requested a subpoena before providing material to Congress.
