LINCOLN – A state lawmaker is formally challenging Nebraska’s rules and regulations on gender care treatments for transgender youths and minors with gender dysphoria. State Sen. Machaela Cavanaugh of Omaha, who staunchly opposed Legislative Bill 574 that granted the rulemaking authority in 2023, has issued a letter to State Sen. Ray Aguilar of Grand Island objecting to the regulations. Aguilar chairs the Legislature’s Executive Board, the highest-ranking committee that oversees internal affairs.
