Former US President Donald Trump and two of his children must answer questions under oath in a New York investigation into their business practices, a judge has ruled.
New York’s attorney general has accused the Trump Organization of obtaining tax breaks and loans through “fraudulent or misleading asset valuations”.
Mr Trump must sit for sworn testimony within 21 days.
He denies the accusations, and is expected to appeal the decision.
He could also invoke his right to remain silent in any deposition.
The Trump Organization said in a statement to the BBC: “The entire system is corrupt.”
On Thursday, New York Supreme Court Judge Arthur Engoron said that Mr Trump, his son Donald Trump Jr, 44, and daughter Ivanka Trump, 40, must each comply with legal orders that prosecutors issued in December.
New York Attorney General Letitia James’ investigation had uncovered “copious evidence of possible financial fraud”, the judge said, giving her a “clear right” to question under oath the former president and two of his children involved in the business.
Mr Trump, 75, has called the investigation politically motivated and a “witch-hunt” by Ms James, a Democrat.
