Arizona and Kansas sue U.S. over voter registration law

From reuters.com:

Kansas and Arizona filed a lawsuit against the U.S. federal government on Wednesday, seeking court approval for states to require proof of U.S. citizenship when registering to vote.

The lawsuit brought by the two Republican-led states accuses an agency of President Barack Obama’s Democratic administration of preventing them from enforcing state laws that require proof of citizenship as a way to prevent illegal immigrants from voting.

The suit, part of an on-going battle over voter registration laws being waged nationwide, demands that the U.S. Election Assistance Commission modify federal voter registration forms to allow states to require proof of citizenship.
