This morning, the Supreme Court heard oral argument in Department of Commerce v. New York concerning whether the plan to include a question on citizenship on the 2020 census violated either the Administrative Procedures Act (APA) or the Constitution's enumeration clause.  Solicitor General Noel Francisco represented the United States in defense of adding the question, and three advocates argued on behalf of Democrat-controlled states, liberal organizations, and the U.S. House against including the question.
