On December 12, 2025, the U.S. Department of Justice filed a lawsuit against the state of Colorado alleging that the state has failed to provide information about voter list maintenance procedures and electronic copies of statewide voter rolls. The lawsuit alleges that Colorado and its Secretary of State Jena Griswold violated the Civil Rights Act of 1960 by refusing to produce a current unredacted electronic copy of the state’s voter registration list. Secretary Griswold expressed concerns over the rights and privacy of the citizens of Colorado after the Department of Justice demanded unredacted voter list data, which would contain personally identifiable information, such as partial Social Security numbers.
