(CNN) The District of Columbia Attorney General's Office has subpoenaed the Trump inaugural committee for documents related to its finances.

The subpoena, dated February 26 and obtained by CNN, says the attorney general, Karl Racine, is investigating "whether the Committee's expenditures of its nonprofit funds were wasteful, mismanaged, and/or improperly provided private benefit, causing the Committee to exceed or abuse its authority or act contrary to its nonprofit purpose."

The new probe indicates widening interest among law enforcement officials into Trump's inaugural, which is also being investigated by prosecutors in New York and New Jersey.

The documents, due by March 29, cover a wide swath of committee activity. The subpoena asks for inaugural committee financial and governance documents, vendor contracts and communications, as well as money the committee paid to the Trump Organization and the Trump International Hotel in downtown Washington. The hotel was a hot place to stay for revelers attending Trump's inauguration in January 2017, and it remains a central hangout for tourists and Trump associates in the city.

The office declined to comment, when reached by CNN. The New York Times first reported the DC attorney general's subpoena.
