LOS ANGELES (AP) – California is suing the Trump administration over its decision to add a question about citizenship to the 2020 U.S. Census. In announcing the lawsuit Tuesday, California Attorney General Xavier Becerra says adding such a question is a reckless decision that would violate the U.S. Constitution and cause a population undercount. California Secretary of State Alex Padilla says the move “rolls back the clock on civil rights and voting rights in America.” The Commerce Department announced the question would be added to the 2020 Census on Monday night, saying it will help enforce the Voting Rights Act. Required by the Constitution, the U.S. Census is taken every 10 years. It helps determine the number of seats each state has in the House and how federal money is distributed to local communities.
