United States v. Thomas

In January 2026, DOJ sued Connecticut, seeking a copy of the state’s complete and unredacted voter roll. This file would include large amounts of private voter information, such as drivers’ license and social security numbers. DOJ’s lawsuit follows an August demand letter, which requested the entire Connecticut voter file. DOJ began sending such demands to dozens of states over the summer of 2025, and then began suing states that refused to comply in September 2025. As of January 2026, DOJ has sued twenty-five states in an attempt to force them to turn over their voter registration files.

DOJ’s lawsuit appears to be connected to governmental efforts to create a national voter database without congressional authorization, and to question the validity of certain states’ election administration process and the status of certain voters.

Common Cause and an individual voter sought to intervene to defend against this potential violation of voter privacy. The voters and organization are represented by the ACLU and the ACLU of Connecticut.
