The bill to require Nebraska voters to show a government-issued photo ID before casting their ballots is scheduled for more debate.
Lawmakers are expected to revisit the bill this week after a two-and-a-half hour debate last week.
Supporters say Legislative Bill 239 is needed to detect and discourage voter fraud in Nebraska.
Opponents call the bill an attempt to make it difficult for seniors and low-income people to vote.
Several lawmakers have lined up amendments designed to create a
filibuster to block the voter ID bill.
Voters would have to show a photo ID in order to cast a ballot
at a polling place. Those without ID could still vote using a provisional ballot that would be verified later. Another option would allow voting by mail without providing the ID.
