(KMTV) — There is a new effort in Nebraska to restrict bathroom and locker room access by gender. Senator Kathleen Kauth introduced a new bill that would require public schools, colleges and state agencies to designate restrooms and locker rooms based on sex and prohibit use by the opposite sex. The issue drew testifiers from both sides of the argument for hours of testimony during a legislative hearing. Kauth says this bill is rooted in legislation that passed last year, using language that lawmakers stripped out during debates. Opponents argue that discussing this again is a waste of time and question how the measure would be enforced.
