Washington state voters approve ban on transgender girls in K-12 sports

Washington state voters approved Initiative 638, which restricts transgender girls from participating in girls' K-12 sports, according to 1190talkradio.iheart.com.

The initiative requires students to submit healthcare documentation verifying their sex before playing on girls' teams, as reported by FourStatesHomepage.com.

This measure is part of a wider trend across the U.S., where 29 states have laws or regulations limiting female school sports participation to students of the female sex, 1190talkradio.iheart.com noted.

Similar measures were also approved recently in Arizona, Colorado, and Nebraska, reflecting a growing national movement to restrict transgender athletes in girls' and women's sports.

The U.S. Supreme Court upheld such state laws in June, rejecting challenges based on Title IX and equal protection arguments, according to 1190talkradio.iheart.com.
