Republican Governor Brad Little of Idaho signed the Fairness for Women in Sports Act. The bill will prohibit biological males who have transitioned to women from competing against women in sports.

“The sports ban applies to all sports teams sponsored by public schools, colleges and universities,” NBC Newsreported. “A girls’ or women’s team will not be open to transgender students who identify as female.”

The act has been welcomed, as many see the inclusion of transgender athletes competing against women as unfair. As a biological male who has transitioned remains at a biological advantage over a female athlete.

“Girls deserve to compete on a level playing field. Allowing males to compete in girls’ sports destroys fair competition and women’s athletic opportunities,” Alliance Defending Freedom (ADF) Senior Vice President of U.S. Legal Division Kristen Waggoner said in a statement sent to The Daily Wire.

“We commend Gov. Little for signing the Fairness for Women in Sports Act into law so that those opportunities will be protected in Idaho,” Waggoner continued. “When the law ignores biological differences, women and girls bear the brunt of the harm.”
