The deposition of Commerce Secretary Wilbur Ross Jr. in a lawsuit over his agency’s decision to ask about immigration status on the 2020 U.S. Census will be delayed until later this month, according to a source involved with the litigation.

Ross, who was originally scheduled to be deposed in the case yesterday, will be out of the country for an extended period of time and won’t be available for the deposition until the week of Oct. 22, two weeks before the case is scheduled to go to trial.
