The U.S. Supreme Court has blocked the New York attorney general from taking the deposition of U.S. Commerce Secretary Wilbur Ross in a lawsuit over his department’s plan to ask about citizenship on the 2020 U.S. census scheduled to go to trial in less than two weeks.

His testimony was delayed indefinitely while the Trump administration formally asks the Supreme Court to review a decision by Judge Jesse Furman of the U.S. District Court for the Southern District of New York that allowed the deposition in the first place.
