KANSAS CITY, Mo. (AP) – Missouri’s voter ID law is facing a legal challenge from a national progressive organization alleging it creates undue burdens for voters who lack the required photo identification.

The Kansas City Star reports that the Democratic-aligned Priorities USA filed the lawsuit on behalf of 70-year-old Mildred Gutierrez of Jackson County.

The lawsuit says Gutierrez’s driver’s license expired in 2016 and she wasn’t eligible for renewal due to her failing vision. The complaint says Gutierrez was informed she wouldn’t be allowed to vote in future elections without a non-driver’s license ID from the state.

The law says a person without a photo ID can cast a ballot if they sign a sworn statement attesting they don’t have required documents. But the lawsuit says the procedural hurdles are “fraught with uncertainty and unwarranted threats of criminal penalties.”
