D.C. attorney general Karl Racine sued President Donald Trump’s inaugural committee and several Trump businesses Wednesday, alleging the committee improperly used nonprofit funds to book a ballroom at Trump’s D.C. hotel during the 2017 inauguration.

In the lawsuit filed in D.C. Superior Court, Racine alleges the Presidential Inaugural Committee violated district law “when it wasted approximately $1 million of charitable funds in overpayment for the use of event space at the Trump Hotel, owned and controlled by the Trump Entities.”
