On December 18, 2025, the U.S. Department of Justice filed a lawsuit against the state of Illinois 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 Illinois and Executive Director of the State Board of Elections Bernadette Matthews violated the Civil Rights Act of 1960 by refusing to produce a current unredacted electronic copy of the state’s voter registration list. Illinois expressed concerns over the rights and privacy of its citizens after the Department of Justice demanded unredacted voter list data, which would contain personally identifiable information, such as partial Social Security numbers.
