(CNN) The attorney general for Washington, DC, filed a lawsuit on Wednesday alleging President Donald Trump's inaugural committee abused non-profit funds by overpaying for event space at the President's Washington hotel for events around his 2017 inauguration.

DC Attorney General Karl Racine filed the suit against the 58th Presidential Inaugural Committee, the Trump Organization and the Trump International Hotel in Washington in DC Superior Court. He accused the inaugural committee of coordinating with the Trump family to "grossly overpay" for event space at the Trump International Hotel.

The inaugural committee wasted approximately $1 million of charitable funds in overpayment for the use of event space at the Trump Hotel in violation of District law, according to the lawsuit.

"The inaugural committee made exorbitant and unlawful payments to the Trump hotel to rent event space for inaugural activity," Racine said.

Nonprofits are legally required to ensure that their funds are used for their stated public purpose, not private interest, he added.
