The U.S. Department of Justice has filed a lawsuit against the state of Oklahoma, alleging that the state is refusing to provide certain voter registration information requested by the federal government. Oklahoma officials have cited state law as preventing the disclosure of driver's license numbers and Social Security numbers, even in partial form.

Why it matters

This lawsuit is part of a broader dispute between some states and the federal government over voter registration data and transparency. The DOJ argues that access to this information is necessary to ensure the integrity of federal elections, while some states contend that protecting voter privacy is a higher priority.

The details

The DOJ filed the lawsuit after an Oklahoma State Election Board official informed the department that state law prevents the disclosure of driver's license numbers or Social Security numbers, even in partial form, as part of voter registration data. The federal government has requested this information from several states as part of its efforts to maintain accurate voter rolls and combat potential fraud.

  • The lawsuit was filed on February 27, 2026.
  • The Oklahoma State Election Board official's response to the DOJ's request occurred earlier in February 2026.
