Fulton County election officials are seeking to block a federal subpoena seeking personal data on thousands of 2020 poll workers, escalating a legal clash with the Justice Department over the scope of its election-related investigation into the Georgia county.

In a motion filed Monday in federal court, the Fulton County Board of Registration and Elections asked a court to quash an April DOJ subpoena filed that requests names, addresses, and phone numbers of election workers who participated in the 2020 vote. County officials said the demand is overly broad and risks exposing private individuals to potential harassment, while also intruding on Georgia’s authority to administer its own elections.
