The U.S. Election Assistance Commission has found that heightened proof-of-citizenship requirements could hinder eligible citizens from voting in federal elections.
Their ruling late Friday denied requests from Kansas, Arizona and Georgia to modify the federal registration form for their residents.
Kansas Secretary of State Kris Kobach says the states now will press their constitutional claims before the U.S. District Court in Kansas.
Kobach says the decision is unconstitutional because it prevents the states from securing their voter rolls.
The group Project Vote calls the ruling a significant decision that underscores the purpose of the National Voter Registration Act to remove barriers.
