Inside a federal courtroom in Concord on Tuesday, lawyers for the State of New Hampshire squared off against the U.S. Department of Justice over a question with significant implications for every registered voter in the state: can the Trump administration compel New Hampshire to turn over a confidential database containing voters’ partial Social Security numbers and driver’s license numbers?

According to NHPR, state attorneys asked U.S. District Judge Joseph Laplante to dismiss the federal lawsuit, arguing there is no legitimate legal basis for the government’s sweeping request. The judge did not issue a ruling from the bench, leaving New Hampshire voters and elections officials to await a decision with broad consequences for voter privacy and state sovereignty over election administration.

What the Federal Government Is Demanding

The Trump administration, through the U.S. Department of Justice, sued New Hampshire Secretary of State David Scanlan after Scanlan refused to comply with a federal demand for access to the state’s comprehensive voter file. That database contains detailed information on every registered voter in New Hampshire, including partial Social Security numbers and state driver’s license numbers, data that elections officials typically guard closely to protect voter privacy and prevent identity theft.

The administration claims it needs the information to verify that New Hampshire is complying with federal voter roll maintenance requirements under the National Voter Registration Act and sections of the Civil Rights Act. DOJ attorney John Casali argued in court Tuesday that the federal government has an obligation to ensure states including New Hampshire are conducting appropriate safeguards to maintain accurate voter rolls and that federal oversight requires access to underlying data.

State attorney Mary Triick pushed back sharply, arguing the administration’s request was “outside the limits” of permissible federal oversight and that the government had provided no specific purpose for sharing the records beyond a generalized claim of oversight authority. Triick told the court the demand lacked a legitimate legal foundation and that compliance would expose sensitive personal information of hundreds of thousands of New Hampshire residents without justification.

New Hampshire’s Long Resistance to the Demand

Tuesday’s hearing was not the first time New Hampshire had resisted the federal voter data request. Secretary of State Scanlan, a Republican, first pushed back in early February 2026 when the administration issued its initial demand. At the time, Scanlan and state officials described the request as “unprecedented” in scope and format, noting that the federal government was asking for data elements it had never previously sought from New Hampshire.

New Hampshire subsequently filed a lawsuit of its own seeking a court declaration that it is not required to comply. The Trump administration then countersued, creating the case now before Judge Laplante. New Hampshire joined a growing roster of states that have declined to comply, forcing the administration into courtrooms across the country to press its case.

The New Hampshire lawsuit is one of approximately 20 similar suits the Trump administration is pursuing against states nationwide, according to court documents and reports from the New England News Collaborative. The pattern suggests a coordinated federal effort to gain access to voter file data in a form that states have historically kept confidential, and that goes beyond the redacted voter information they are accustomed to sharing with federal authorities.

Why Voter Data Privacy Matters to New Hampshire Residents

The specific data elements at issue, partial Social Security numbers and driver’s license numbers, are not typically available on public voter rolls. New Hampshire, like most states, provides a version of its voter file to political parties, campaigns, and researchers, but that version omits sensitive identifiers. The data the Trump administration is seeking is a more complete version maintained internally by the Secretary of State’s office and used primarily for voter registration maintenance.

Privacy advocates and civil liberties organizations have warned that the federal demands, taken together across 20 states, would create a massive national repository of linked voter identity information with no clear legal authorization or privacy safeguards. The Campaign Legal Center, a nonpartisan election law organization, has argued that the administration’s attempts to obtain sensitive voter data “threaten the rule of law” by asserting executive oversight powers that Congress has not granted.

For New Hampshire voters specifically, the stakes include the protection of their Social Security and driver’s license numbers from potential exposure or misuse if the federal government obtained and stored the data without adequate security protocols. The state has about 900,000 registered voters.

The Broader Context: Federal Voter Roll Pressure

The Trump administration has made aggressive enforcement of voter roll maintenance a stated priority. Federal law requires states to take reasonable steps to remove outdated registrations, such as those belonging to people who have moved or died. The administration argues that access to comprehensive voter data is necessary to audit whether states are doing this effectively.

Critics, however, note that New Hampshire already submits regular reports to federal authorities on its voter roll maintenance activities and that the state has a well-regarded elections infrastructure. Scanlan’s office has defended its compliance with federal law while arguing that the specific data demand exceeds what the law requires states to provide.

The hearing Tuesday drew attention from elections officials and voting rights observers across New England, who are watching to see whether Judge Laplante’s eventual ruling will set a precedent for how far federal authority extends over state voter databases. A ruling in the administration’s favor could open the door for similar data demands to be enforced in other states currently resisting compliance.

For now, New Hampshire’s voter data remains in state hands while Judge Laplante considers both sides’ arguments. No timeline for a ruling was announced following Tuesday’s proceeding.

What data is the Trump administration trying to get from New Hampshire? The administration is seeking access to a comprehensive voter database that includes partial Social Security numbers and state driver's license numbers for all registered voters. This is more sensitive than the voter roll information New Hampshire typically shares with campaigns and the public.
Why did New Hampshire's Secretary of State refuse to comply? Republican Secretary of State David Scanlan and state attorneys argue the federal demand is "outside the limits" of permissible federal oversight and that the government provided no clear legal justification for needing the sensitive identifying information. New Hampshire contends it is already in compliance with federal voter roll maintenance laws.
Is New Hampshire the only state fighting the Trump administration over voter data? No. New Hampshire's case is one of approximately 20 similar lawsuits the Trump administration has filed against states nationwide that refused to turn over their voter databases. The pattern of cases reflects a coordinated federal push to access state voter data in a more detailed form than states have historically provided.
Who is Judge Joseph Laplante and when might he rule? Judge Joseph Laplante serves on the U.S. District Court for the District of New Hampshire in Concord. He heard arguments on Tuesday, May 26, 2026, but did not issue an immediate ruling. No timeline was announced for when a decision might come.
What happens if the federal government wins the lawsuit? If Judge Laplante rules in the administration's favor, New Hampshire would likely be required to provide the requested voter database to the U.S. Department of Justice. A ruling in the state's favor would dismiss the federal lawsuit, allowing New Hampshire to withhold the data. Either outcome could be appealed to the First Circuit Court of Appeals.

New Hampshire voters and elections observers are closely watching the case alongside several other active legal battles over voting rights in the state. Earlier this year, the Legislature passed restrictions that banned the use of college-issued school IDs for voter identification, drawing pushback from students and civil liberties advocates. Together, these developments paint a picture of an election administration landscape in New Hampshire that is under significant pressure from multiple directions as the 2026 elections approach.

The state’s general elections voting guide continues to be updated as the legal and legislative landscape evolves, providing residents with current information on registration requirements and acceptable identification.
