Sources tell ABC News the tapes were provided as part of that congressional subpoena issued to Parnas, and the former Giuliani ally also provided a number of documents both in English and Ukrainian to the committee in two separate productions, sources told ABC News.

However, some of the material sought by congressional investigators is already in possession of federal investigators within the Southern District of New York and thus held up from being turned over, according to sources familiar with the matter.

Parnas' associate, Fruman, has not cooperated with the committee.

Giuliani's relationship with Parnas and Fruman is the subject of a criminal investigation in the Southern District of New York, according to sources. That case will have its next court date early next month.
