Civil rights groups, including the NAACP and ACLU are ready to challenge North Carolina's new election laws.

FOX News Radio's Rich Johnson reports from Washington:

North Carolina's Governor says it's about the integrity of every vote cast in his state.

Adam Stein, representing the NAACP in Durham, has a different view.

(Stein) "This is the most aggressive piece of discriminatory legislation that I can remember."

Three groups are suing to overturn the law that requires a photo ID of all North Carolina voters. The suit says that violates the 14th and 15th Amendments, and a section of the Voting Rights Act that bans discrimination on the basis of race, color, or language.
