Federal prosecutors in New York have ordered President Trump’s inaugural committee to turn over documents relating to its donors, finances and event attendees, the New York Times reports, citing sources with knowledge of the investigation.

Details: The news was first reported by ABC News on Monday evening, which noted that specific details of the request remain unclear, and that the investigation — which comes as many observers have speculated that special counsel Robert Mueller is nearing to his Russia probe — is zooming in on Trump's political fundraising both before and after his 2016 presidential election.

Prosecutors in New York’s Southern District are reportedly interested in whether foreign nationals funneled donations into the committee, which would be illegal under law.

A spokesman for the inaugural committee, a nonprofit in charged of organizing festivities surrounding the wearing-in ceremony, told ABC News: "We have just received a subpoena for documents. While we are still reviewing the subpoena, it is our intention to cooperate with the inquiry."

A spokesman for the U.S. attorney’s office in Manhattan declined to comment.

Trump’s former personal attorney Michael Cohen "has been extensively interviewed by prosecutors in the Southern District office," per ABC News.
