Why It Matters
A federal court confirmation that the U.S. Department of Justice is sharing state voter roll data with the Department of Homeland Security has significant implications for election administration and data privacy across the country, including in states like Idaho that have already complied with federal data requests. The disclosure clarifies the scope of a sweeping federal effort to cross-reference voter registration records with immigration databases in advance of the 2026 midterm elections.
The development raises questions about how sensitive personal information — including partial Social Security numbers and driver’s license data — is being used and stored by federal agencies, and what legal authority governs that process.
What Happened
During a federal court hearing on Thursday, March 27, 2026, 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. The hearing centered on the DOJ’s lawsuit seeking Rhode Island’s voter rolls as part of a broader federal effort to audit state compliance with federal voting rights laws.
U.S. District Court Judge Mary McElroy asked directly whether the Justice Department could send state voter lists to Homeland Security with instructions to search for noncitizens. DOJ attorney Neff responded affirmatively: “Yes, and we intend to do so.” He added that the two agencies already have a formal “use agreement” in place governing such data sharing.
Despite confirming the data sharing arrangement, the DOJ denied that it is constructing a national voter database. The distinction between a data-sharing program for immigration enforcement purposes and a centralized national voter registry remains a point of legal and political contention.
By the Numbers
- 29 states and the District of Columbia have been sued by the DOJ for refusing to provide voter roll data to federal authorities.
- At least 12 states have voluntarily complied and turned over their voter lists to the Justice Department.
- 3 federal judges have rejected the DOJ’s demands for state voter data; no federal judge has yet ruled in the department’s favor.
- 0 confirmed cases of widespread noncitizen voting have been documented in recent federal elections, with experts and election officials describing the phenomenon as extremely rare.
- Oral arguments on the DOJ’s appeals are scheduled for later this spring, with the Trump administration seeking expedited rulings ahead of the November 2026 midterms.
Zoom Out
The DOJ’s voter data campaign is part of a broader Trump administration initiative to tighten election integrity enforcement using federal agency coordination. The effort represents one of the most expansive federal interventions into state-managed voter rolls in modern U.S. history.
States across the country — including blue and red states alike — have pushed back on the data demands, citing concerns about voter privacy, data security, and federal overreach into election systems that are constitutionally managed at the state level. Legal challenges have been filed in multiple jurisdictions, and the appellate courts are expected to provide clearer guidance on the limits of federal authority in this area.
The Department of Homeland Security had previously acknowledged the data-sharing arrangement in an unsigned statement provided to the news outlet Stateline in September 2025. However, the confirmation by a DOJ attorney in open court on Thursday marked the first formal, on-record acknowledgment of the arrangement. CBS News reported separately on Thursday that the two agencies were near finalizing a comprehensive agreement specifically governing voter data sharing for immigration enforcement purposes.
Noncitizen voting in federal elections is already illegal under existing federal law, and election officials in both parties have consistently stated that such cases are exceptionally rare and typically the result of administrative errors rather than intentional fraud.
What’s Next
The DOJ’s appeals of three adverse lower court rulings are expected to move quickly, with oral arguments scheduled in the coming weeks. The administration has made clear it wants binding legal authority to obtain the data well before the 2026 midterm election cycle is underway.
Congress may face renewed pressure to weigh in on the boundaries of federal access to state voter data, particularly as appellate courts work through the constitutional questions around federalism and data privacy that the litigation has raised. States that have not yet complied with federal data requests are watching the appellate proceedings closely before deciding how to respond.
