SPRINGFIELD — The Trump administration’s lawsuits seeking access to sensitive voter registration data in Illinois and dozens of other states is one part of a broader effort to purge state voter rolls of suspected noncitizens, according to documents filed recently in federal court in Springfield.

Those documents were filed Thursday, April 30, by attorneys representing the Illinois AFL-CIO and other groups that have intervened in the case seeking to prevent the Department of Justice from obtaining the information. They say it proves the agency’s stated reasons for seeking the data — to determine whether Illinois is complying with voter list maintenance requirements — is only a pretext and the agency’s suit against the state should be dismissed.

Read the filing

Several former DOJ attorneys who have worked in the Voting Section of the Civil Rights Division filed an amicus brief in the case in March, arguing the agency has no statutory authority to seek the information to conduct its own list maintenance program or to identify noncitizens.

The new documents filed Thursday include internal DOJ emails that the attorneys say were made available “in response to a public records request lawsuit.”

One of those was a June 16, 2025, email from Michael Gates, who was then a deputy assistant attorney general in DOJ’s Civil Rights Division, to his superior, Assistant Attorney General Harmeet Dhillon, who oversees that division. In that email, Gates states that the division is seeking access to the Department of Homeland Security’s Systematic Alien Verification for Entitlements, or SAVE, database.

“This will be helpful to us because it will allow us to compare this SAVE database against states’ voter rolls, which we will get directly from states under the (National Voter Registration Act),” Gates wrote.

The next month, on July 28, DOJ sent its first letter to the Illinois State Board of Elections seeking access to Illinois’ complete, unredacted statewide voter registration list, indicating that it was part of DOJ’s efforts to enforce voter list maintenance provisions of NVRA. The letter was signed by Gates. It also bore the name of Maureen Riordan, acting chief of the Voting Section within the Civil Rights Division.

Gates has since left the Justice Department. He is currently a Republican candidate for California attorney general in that state’s upcoming June 2 primary.

SAVE database

The SAVE database was originally set up to help states verify the citizenship and immigration status of people applying for public benefits such as Medicaid and SNAP, the Supplemental Nutrition Assistance Program. Some states also use it to verify people’s eligibility to vote.

But the program has also been the target of criticism because of its tendency to misidentify people as noncitizens due to its use of incomplete or inaccurate data.

On April 21, the watchdog groups Common Cause and Citizens for Responsibility and Ethics in Washington, or CREW, filed a lawsuit against DOJ in federal court in Washington, D.C., alleging the agency wants to use state voter registration lists and the SAVE database to conduct what they call “a sprawling new voter surveillance and purging apparatus that endangers millions of Americans’ fundamental voting and privacy rights.”

A second document filed last week in the Illinois case is a Nov. 18, 2025, email from the acting chief of the Civil Rights Division’s Voting Section, Eric Neff, that appears to suggest how the agency should conceal its intentions when asked why it is seeking states’ voter registration databases.

“I believe our reply should always be: ‘We will use the data in a manner consistent with Federal law’ and say nothing more,” Neff wrote to fellow DOJ lawyers Jesus Osete and Matt Zandi. He also said of the Help America Vote Act, the Civil Rights Act and NVRA, “none of them require (us) to give the states information about what we are going to do with the data. No judge will have authority to limit us beyond a promise of Federal law compliance.”

Illinois lawsuit

Illinois has refused to hand over an unredacted voter registration list. Instead, it has provided DOJ with electronic copies of partially redacted files that do not include sensitive information such as dates of birth, driver’s license numbers or partial Social Security numbers.

In December, DOJ filed suit in the Central District of Illinois seeking access to the unredacted files. It also filed similar suits in 29 other states and Washington, D.C.

The Illinois AFL-CIO, Common Cause several and other groups have intervened as codefendants in the case.

Attorneys for the state and the intervening parties have filed motions to dismiss the DOJ lawsuit. Judge Colleen Lawless has not yet ruled on the motion. Similar suits have already been dismissed in six other states. No court has yet ruled in favor of DOJ’s request for access to the unredacted voter files.
