The subpoena requests documents related to the committee’s donors and spending, according to the Journal, which said it had viewed a copy of the subpoena.

In December, the newspaper reported that federal prosecutors were investigating whether the inaugural committee misspent some of the record US$107 million it had raised from donors.

The investigation is examining whether some of the committee’s donors gave money in exchange for policy concessions, influencing administration positions or access to the incoming administration, the Journal reported.

A spokeswoman for the committee told the newspaper in a statement: “We have just received a subpoena for documents. While we are still reviewing the subpoena, it is our intention to cooperate with the inquiry.”
