Petitions seeking to repeal Omaha’s new legal protections for gay and transgender residents are now being circulated.

The Omaha World-Herald reports that organizers must gather about 11,400 valid signatures over the next month to put the measure before voters.

A local tea party organizer and clergy and Christian groups are supporting the effort.

The Omaha City Council narrowly approved the ordinance in March that bans employers, job-training programs, labor groups and other organizations from discriminating based on a person’s sexual orientation. The measure included exemptions for religious organizations.

The Lincoln City Council adopted a similar ordinance in May, but opponents mounted a successful petition drive that requires the council to either let the ordinance die or submit it for voter approval. The public vote has not yet been scheduled.
