More civil rights groups are challenging a federal judge's ruling that a law requiring Alabama voters to show a valid photo ID is not discriminatory.
Alabama has required voters to present government-issued photo identification at the polls since 2014. The Alabama NAACP and Greater Birmingham Ministries sued over the law in 2015, arguing it disproportionately affects minorities.
U.S. District Judge L. Scott Coogler ruled in favor of the state in January. He concluded the state helps voters get IDs and Alabama Secretary of State John Merrill offered a mobile service to make home visits.
The plaintiffs appealed the ruling on Feb. 21. The ACLU of Alabama, ACLU Voting Rights Project, Lawyers' Committee and Campaign Legal Center submitted a brief in support on Thursday.
Plaintiffs are asking for a rescheduled trial before the state's primary elections in June.
