New Hampshire Gov. Chris Sununu (R) signed a new bill into law that will require unregistered voters to provide documentation, without exception, to prove their identity and citizenship before voting on Election Day.

The law adds the need for photo identification to cast a ballot and demands that first-time voters show proof of citizenship. The law does not take effect until after the November elections.

The new law goes into effect after the November election, when proof-of-citizenship will be required to register and a photo ID will be required to vote. Critics say it could disenfranchise qualified voters.
