Nebraska lawmakers are wrangling over a measure that would require voters to show a government-issued identification card or registration papers before they could vote.
Fremont Sen. Charlie Janssen told lawmakers Tuesday that his bill seeks to fight the threat of voter fraud, a problem that critics say doesn't exist.
Janssen says his proposal would reduce fraud and is not restrictive, because registered voters without IDs would still be allowed to vote provisionally.
Counties would then verify their identities for their ballots to count.
Critics say the law disproportionately affects poor and young voters.
The group Nebraskans for Civic Reform says between 50,000 and 100,000 Nebraskans do not have identification that would qualify as valid.
Lawmakers were not expected to vote on the measure until Wednesday.
