WASHINGTON - Ivanka Trump has been deposed by attorneys alleging that President Donald Trump's 2017 inauguration committee misused donor funds, a new court filing reveals.

The document, first reported by CNN Wednesday, notes that Ivanka Trump, the president's oldest daughter and a senior White House adviser, was interviewed Tuesday by attorneys from the Washington, D.C., attorney general's office.

The office has filed a lawsuit alleging waste of the non-profit's funds, accusing the committee of making more than $1 million in improper payments to the president's Washington, D.C., hotel during the week of the inauguration in 2017.

As part of the suit, they have subpoenaed records from Ivanka Trump, first lady Melania Trump, Thomas Barrack Jr., a close friend of the president who chaired the inaugural committee, and others. Barrack was also deposed last month.

Trump's inaugural committee spent more than $1 million to book a ballroom at the Trump International Hotel in the nation's capital as part of a scheme to “grossly overpay” for party space and enrich the president's own family in the process, the District of Columbia's attorney general, Karl Racine, alleges.

He has accused the committee of misusing non-profit funds and co-ordinating with the hotel's management and members of the Trump family to arrange the events.

“District law requires nonprofits to use their funds for their stated public purpose, not to benefit private individuals or companies,” Racine has said. “In this case, we are seeking to recover the non-profit funds that were improperly funneled directly to the Trump family business.”

The committee raised an unprecedented $107 million to host events celebrating Trump's inauguration in January 2017, but its spending has drawn continued scrutiny.
