NH Youth Movement filed the suit in U.S. District Court, naming N.H. Secretary of State David Scanlan as the defendant

A new lawsuit from the New Hampshire Youth Movement, filed in federal court on Tuesday, alleges that the law violates the U.S. Constitution by making it “substantially harder — and in some cases impossible — for many New Hampshire citizens to register and vote.” They're asking the court to permanently block the law from taking effect.

A new law in New Hampshire will require anyone registering to vote for the first time in the Granite State to provide documentation they are U.S. citizens, like a birth certificate or passport.

The new law requires all voters to present documentary proof of citizenship to register and a photo ID to vote. The legal challenge by the New Hampshire Youth Movement seeks to permanently block it from going into effect.
