The U.S. Department of Justice said on Friday it sued the state of Virginia for violating the federal prohibition on systematic efforts to remove voters within 90 days of an election.

On Aug. 7, Republican Governor Glenn Youngkin signed an executive order requiring the commissioner of Department of Elections to certify that the department was conducting “daily updates to the voter list” to remove, among other groups, people who are unable to verify that they are citizens to the Department of Motor Vehicles.

U.S. citizens who were identified and notified, and did not affirm their citizenship within 14 days would be removed from the list of registered voters, the Justice Department said. It said this practice has led to citizens having their voter registrations canceled ahead of the Nov. 5 election.

“By cancelling voter registrations within 90 days of Election Day, Virginia places qualified voters in jeopardy of being removed from the rolls and creates the risk of confusion for the electorate,” said Assistant Attorney General Kristen Clarke.
