Ivanka Trump, the US president's daughter and adviser, was questioned under oath this week as part of a civil lawsuit alleging misuse of non-profit funds for Donald Trump's inauguration four years ago. District of Columbia Attorney General Karl Racine's office disclosed in a court filing that the deposition had taken place on Tuesday. In a January 2020 lawsuit, Mr Racine claimed Mr Trump's real estate business and other entities misused non-profit funds to enrich the Trump family. According to the suit, a tax-exempt non-profit corporation called the 58th Presidential Inaugural Committee co-ordinated with the Trump family to grossly overpay for event space in the Trump International Hotel in Washington. Mr Racine's lawsuit alleged that, in one case, the non-profit paid more than $300,000 (about £225,000) to hold a private reception at the Trump hotel for the president's three oldest children – Donald Jr, Ivanka and Eric – on the inauguration evening of January 20, 2017. “District law requires non-profits to use their funds for their stated public purpose, not to benefit private individuals or companies,” Mr Racine said earlier this year.
