Nebraska’s Republican Gov. Jim Pillen on Wednesday signed an executive order strictly defining a person’s sex.

The order notably does not use the term “transgender,” although it appears directed at limiting transgender access to certain public spaces. It orders state agencies to define “female” and “male” as a person’s sex assigned at birth.

“It is common sense that men do not belong in women’s only spaces,” Pillen said in a statement. “As Governor, it is my duty to protect our kids and women’s athletics, which means providing single-sex spaces for women’s sports, bathrooms, and changing rooms.”
