United States v. Pennsylvania

DOJ sued Pennsylvania, seeking the state’s voter rolls, including large amounts of private voter data, such as social security numbers. DOJ’s lawsuit follows letters from DOJ seeking information about certain groups of Pennsylvania voters, including voters who have previously lived out of state, and voters who registered to vote by mail. DOJ sent such letters to dozens of States over the summer of 2025, and then filed a tranche of eight lawsuits against states with Democratic administrations in September 2025.

DOJ’s lawsuit appears to be connected to governmental efforts to create a national voter database without congressional authorization, and to question the validity of certain states’ election administration process and voter rolls, and the status of certain voters.

A group of eight Pennsylvania voters as well as the League of Women Voters of Pennsylvania and Common Cause sought to intervene to defend against this potential violation of voter privacy. The voters and organizations are represented by the ACLU, the ACLU of Pennsylvania, and the Public Interest Law Center.

Notably, a number of the individual voters are Pennsylvanians whose mail ballots were subjected to bogus and illegal mass challenges in 2024 by self-proclaimed “election integrity” advocates. Indeed, persons associated with that failed effort to disenfranchise Pennsylvania voters are now working for or consulting with the federal government regarding “election integrity.”
