'The voter rolls are still dirty. We know it, and now we can prove it,' COF President Chuck Muth told The Federalist. We've been 'trying to get guidance from [Secretary Aguilar] for months on how to do these [challenges]' ... but 'weren't getting any cooperation.' The lawsuit comes after Secretary of State Cisco Agular instructed local officials to reject voter roll challenges that did not comply with his office's interpretation of the law. The Citizen Outreach Foundation is questioning a memo from Nevada Secretary of State Cisco Aguilar telling local officials to reject certain voter roll challenges. Nevada's adoption of an all-mail voting system has made its voter roll problems 'worse,' according to Chuck Muth.
