LINCOLN, Neb. (AP) — A bill that would require Nebraska voters to show government-issued photo identification at the polls is headed to the full Legislature for debate.

The Government, Military and Veterans Affairs Committee voted 7-1 on Wednesday to advance the measure. Opponents have promised to filibuster the bill on the legislative floor and file a lawsuit if the bill becomes law.

The proposal by Sen. Tyson Larson of O’Neill would require voters to show a driver’s license, state ID card or other government-issued photo identification.

An amendment backed by the committee would also allow for the use of tribal identification or county-issued voter registration acknowledgements.

Voters who cast ballots early or by mail would not have to provide identification unless they’re voting for the first time.
