A Kentucky elections official announced on Tuesday an effort seeking to block the Trump administration’s push to examine extensive voter records.

Jefferson County Clerk David Yates said he is pushing back after Kentucky was among an additional five states the Justice Department sued last month “for failure to produce their full voter registration lists.” Yates said he filed a motion on Monday in the District Court for the Eastern District of Kentucky to intervene in the lawsuit, arguing that releasing completely unredacted voter rolls would violate state privacy laws and jeopardize sensitive data.
