Civil rights groups are asking a federal court to block the Justice Department immediately from using election materials seized in a January raid of a Fulton County elections facility, warning that the data could be repurposed to build what they described as a “national voter database” of eligible voters.

In a motion filed late Sunday, the NAACP and allied organizations argued that Georgia voters entrusted the state with “sensitive personal information” when registering to vote and that the Jan. 28 seizure of ballots and related records “breached that guarantee, infringed constitutional protections of privacy, and interfered with the right to vote.”
