Why It Matters
The federal government’s effort to identify noncitizen voters has taken on new legal and administrative dimensions, with the Department of Justice confirming in open court that sensitive voter registration data is being shared with the Department of Homeland Security. The disclosure has implications for every state in the union, including Idaho, as the Trump administration presses forward with a broad initiative to verify voter rolls ahead of the 2026 midterm elections.
States that have refused to comply with federal data demands now face active litigation, and those that have complied are part of an inter-agency data-sharing arrangement whose scope is still being defined in courtrooms across the country.
What Happened
During a federal court hearing Thursday in Providence, Rhode Island, Department of Justice attorney Eric Neff confirmed that voter data collected from states is being shared with the Department of Homeland Security as part of an effort to identify noncitizen voters. U.S. District Court Judge Mary McElroy directly asked whether the Justice Department could send Rhode Island’s voter list to Homeland Security with instructions to cross-reference it for noncitizens.
“Yes, and we intend to do so,” Neff told the court. He also noted that a formal “use agreement” between the two agencies is already in place governing such data transfers.
Neff was careful to state that the Justice Department is not building a national voter database, a distinction the department has maintained as legal challenges to its data-collection effort have mounted in courts across the country.
The Justice Department has demanded that states hand over full copies of their voter rolls, including sensitive personal information such as driver’s license numbers and partial Social Security numbers. The stated justification is ensuring state compliance with federal voting laws that require regular maintenance and updating of voter registration lists.
By the Numbers
- 29 states plus the District of Columbia have been sued by the Justice Department for refusing to turn over voter data.
- At least 12 states have voluntarily complied with the federal data request.
- 3 federal judges have rejected the Justice Department’s demands so far; none have ruled in the department’s favor.
- 0 documented cases of widespread noncitizen voting have been cited by the government, which acknowledges the practice is extremely rare.
- Spring 2026 is the target timeline for appellate oral arguments, as the administration seeks rulings before the midterm election cycle intensifies.
Zoom Out
The confirmation of inter-agency data sharing marks an escalation in the Trump administration’s push to verify voter eligibility through federal data systems. While Thursday’s court statement from DOJ attorney Neff was the first on-the-record acknowledgment of the sharing arrangement, the Department of Homeland Security had indicated as early as September 2025 that the collaboration was underway.
CBS News reported Thursday that the two agencies are also nearing a final formal agreement on sharing voter data specifically for immigration enforcement purposes, signaling that the program may expand beyond its current scope.
The legal landscape remains largely unfavorable for the administration at the district court level. All three judges who have ruled on the matter have sided with states resisting the data demands. The Justice Department has appealed each of those decisions, and the cases are expected to move quickly through the appellate process given the administration’s push to resolve them before the 2026 midterms.
Across the Mountain West and Pacific Northwest, states have taken varying postures on the data requests. The outcome of the pending appeals will likely determine whether holdout states are ultimately compelled to comply or whether the federal data-collection effort is curtailed by the courts.
What’s Next
Oral arguments in the Justice Department’s appeals are scheduled for later this spring. A ruling in favor of the administration could force dozens of states to hand over voter roll data to both DOJ and DHS. A ruling against the department could effectively end the federal effort to compel state compliance.
The Rhode Island case, where Thursday’s disclosure occurred, will continue to move through the courts. Additional hearings are expected as Judge McElroy evaluates the department’s data request against state objections rooted in voter privacy concerns and federal overreach arguments.
Congress has not acted to codify or restrict the data-sharing arrangement, leaving the matter’s resolution largely in the hands of the federal judiciary for the foreseeable future.
