Immigrant Rights Group Sues to Block Federal Database Use for Voter Purges

An immigrant rights group filed a lawsuit on September 3, 2026, seeking to block the Trump administration from using federal databases to identify and potentially purge voters from rolls, arguing that the process could wrongly remove legal voters. The lawsuit specifically challenges the administration's review of California's voter list and a request for voter information, claiming the Department of Homeland Security's assertion of 250,000 noncitizens on rolls in four states, including California, lacks evidence and could misuse sensitive personal data.
