The national League of Women Voters and the group's Kansas and Arizona chapters are seeking to intervene in a federal lawsuit over proof-of-citizenship laws in the two states.
The groups filed their requests Thursday in a federal court case in Kansas. The national advocacy group Common Cause, three Arizona-based Hispanic-rights groups and an Arizona political consultant also filed requests to intervene.
Last week, a Washington-based voter registration group, three Arizona-based advocacy groups and an Arizona state senator sought to intervene.
The lawsuit was filed in August by Kansas and Arizona and Secretaries of State Kris Kobach and Ken Bennett.
They're trying to force the federal government to modify a national voter registration form to help the states enforce policies that require new voters to produce citizenship papers when registering.
