Federal officials are pressing Illinois election authorities to hand over the state’s unredacted voter registration database.

The U.S. Department of Justice has given the State Board of Elections until Monday, September 1st, to comply.

Illinois previously provided a version of the voter list that includes names, addresses, voting history, and registration dates. But sensitive information such as birth dates, driver’s license numbers, and portions of Social Security numbers was redacted under state and federal privacy laws.

The Justice Department says it needs the full, unredacted database to review whether Illinois is complying with the National Voter Registration Act, which requires states to keep voter rolls accurate by removing registrations for people who have died, moved, or are otherwise ineligible.

Federal officials are also requesting data on voter removals since 2022 and a list of election officials responsible for maintaining the rolls. The state elections board maintains that releasing the additional personal information would violate both federal and Illinois privacy protections.

The Justice Department has not explained why it considers the unredacted data necessary for its review.
