Louis Nelson reports for Politico that New York Attorney General Eric Schneiderman has lined up 16 other states, the District of Columbia, and six large cities to sue the Commerce Department and the Census Bureau over asking about U.S. citizenship on the 2020 census. Schneiderman says the citizenship question “will fatally undermine the accuracy of the population count and cause tremendous harms.” The lawsuit, filed April 3, says, “As defendants’ own research shows, this decision will ‘inevitably jeopardize the overall accuracy of the population count’ by significantly deterring participation in immigrant communities, because of concerns about how the federal government will use citizenship information.... These concerns have been amplified by the anti-immigrant policies, actions, and rhetoric targeting immigrant communities from President Trump and this Administration.” New York, Connecticut, Delaware, Illinois, Iowa, Maryland, Minnesota, New Jersey, New Mexico, North Carolina, Oregon, Rhode Island, Vermont, Washington, Massachusetts, Pennsylvania and Virginia are listed as plaintiffs in the lawsuit, with the District of Columbia, New York City; Chicago; Philadelphia; Providence, Rhode Island; Seattle; and San Francisco and the U.S. Conference of Mayors.
