The Trump administration is suing Nevada over state election officials’ refusal to provide the Department of Justice with voters’ driver's license and partial Social Security numbers.

The lawsuit — filed Thursday in Nevada federal court — is a major escalation of the Justice Department’s efforts to obtain Nevada voters’ personal information. It argues the U.S. attorney general has “sweeping power” to obtain voter data from states and asks the court to require the release of the data. Similar lawsuits were filed in three other states on Thursday, bringing the total number of lawsuits to 18.

In August, the agency sent a letter to state election officials asking for this information. In response, Nevada’s secretary of state’s office said it would need more time to assess the legality of the “unprecedented” request. Secretary of State Cisco Aguilar, a Democrat, said in a statement it was an effort “to intimidate us into turning over protected voter data.” States are responsible for administering elections.

Thursday’s lawsuit states the Justice Department never heard from Nevada election officials following this initial response.

Last month, Aguilar and nine other secretaries of state asked for clarification on how the data would be used and whether it would be shared with the Department of Homeland Security. When asked for clarification, a Justice Department spokesperson referred to the press release announcing the lawsuits.

In a statement Friday, Aguilar said his office and the attorney general’s office is working to evaluate the lawsuit.

“The Department of Justice is making sweeping demands of states to hand over private voter data. Despite our simple requests for information on how they’re going to keep this data secure, they’ve given us no clear answers,” Aguilar’s statement said. “While these requests may seem like normal oversight, the federal government is using its power to try to intimidate states and influence how states administer elections ahead of the 2026 cycle.”

The secretary of state’s office also said it has not yet been served by the Justice Department in the lawsuit.

The monthslong dispute between the Trump administration and state election officials began in June. 

The Justice Department sent a letter requesting copies of Nevada’s “statewide voter registration list” and other information on how the state complies with federal election laws. One month later, the state responded with a link to the latest statewide voter registration list, which includes a voter’s name, date of birth, address and political party, all of which is already on public record. But Thursday’s lawsuit called this the “purported” voter registration list, and its subsequent correspondence asks for “all fields” associated with a voter’s registration.

In its August request for the personal information, the Trump administration said it was an effort to assess Nevada’s compliance with federal requirements on maintaining voter registration lists. Federal officials referred to civil rights law that prohibits the public release of this information unless compelled to do so by a court or Congress, but they did not say how they would use this data.

The secretary of state’s office said in August that providing such information “would expose highly sensitive information that is confidential.” It also objected to arguments that the state might be in violation of federal voting laws, saying there was “no basis” to the allegations.

The Trump administration has frequently sought data from states — including on matters outside of elections. For example, the Department of Agriculture asked states to hand over personal data of food stamp recipients, which Nevada has “fully complied with,” according to court records. The Trump administration recently said it will withhold food stamp benefits to states that do not provide recipient data.

U.S. Immigration and Customs Enforcement has also issued subpoenas to certain localities for the personal information of noncitizens.
