Why It Matters
The Trump administration is intensifying efforts to reshape election administration across the country by targeting noncitizen voting and voter registration practices. Illinois and dozens of other states now face federal pressure and litigation over access to voter databases and mail-ballot procedures, marking a significant clash between the executive branch and state election authorities.
What Happened
The U.S. Department of Justice sent a letter on July 7 to the Illinois State Board of Elections threatening criminal prosecution of state officials who allow noncitizens to vote. The letter, addressed to ISBE Executive Director Bernadette Matthews and signed by Harmeet Dhillon, head of the DOJ’s Civil Rights Division, was part of a coordinated effort targeting all 50 states and Washington, D.C.
The DOJ warned that “any election officer, including the chief election officer of the state, who knowingly retains noncitizens on the state’s (State Voter Registration List) or facilitates noncitizens in receiving ad casting ballots could be subject to criminal liability.” The letter gave Illinois five days to respond with details on how the state plans to comply with federal voting eligibility laws.
The Illinois State Board of Elections said as of Wednesday it is “reviewing” the letter. The three-page notice also demands information about Illinois’s procedures for preventing noncitizen participation in elections.
Separately, the DOJ has sued Illinois and dozens of other states seeking access to complete, unredacted voter registration databases containing dates of birth, driver’s license numbers, and partial Social Security numbers. The administration has not prevailed in any of these database lawsuits to date.
By the Numbers
July 7 — date DOJ sent the letter to Illinois and other states
50 states plus D.C. — jurisdictions receiving similar DOJ letters
5 days — deadline for Illinois to respond to DOJ demands
3 pages — length of the DOJ letter
Related Actions and Legal Challenges
The noncitizen voting letter is part of a broader Trump administration campaign to restructure election procedures. In March, President Trump issued an executive order directing the Department of Homeland Security to compile lists of eligible voters for each state ahead of the 2026 election.
Illinois Attorney General Kwame Raoul joined a coalition of 22 other states and Washington, D.C. in challenging that executive order. On June 25, a federal judge in Massachusetts struck down major provisions of the order, temporarily halting key elements of the administration’s voter-list initiative.
The administration has also proposed regulations that would prohibit the U.S. Postal Service from sending mail-in ballots to voters not on a federally approved eligible voter list. Governor JB Pritzker joined a coalition of eight Democratic governors opposing the USPS rule on July 2. Raoul participated in a separate coalition of 24 state attorneys general also opposing the rule. A federal judge in Massachusetts has already blocked the mail-ballot prohibition effort.
Zoom Out
The Trump administration’s push represents a significant expansion of federal involvement in state election administration, traditionally a domain controlled by the states under the Constitution. Election officials across the country are navigating competing demands from federal authorities and state leadership as litigation over voter databases and ballot procedures continues in federal courts.
State attorneys general and governors from both parties have filed multiple legal challenges to administration initiatives, arguing that federal overreach threatens state sovereignty over elections. However, federal judges have already blocked some of the most contested proposals, signaling potential legal obstacles to the administration’s agenda.
What’s Next
Illinois must respond to the DOJ’s noncitizen voting letter within the five-day window. Ongoing litigation over voter database access and mail-ballot rules will likely determine the scope of federal authority over state election procedures. The administration may pursue additional enforcement actions or regulatory changes as the 2026 election cycle approaches.
