Commerce Secretary Wilbur Ross said Tuesday that his department was still considering whether it would add a question asking people to state their citizenship as part of the upcoming 2020 Census, reinstating a practice that was dropped in 2010 during the Obama administration.

The Justice Department inquired last year whether such a question could be added to the once-a-decade survey of the U.S. population, the government’s source of statistical information regarding the country. President Trump has said the question should be added.
