Voters in Washington state could approve an anti-transgender law, Initiative Measure No. IL26-638, which would require girl student-athletes statewide to confirm their "biological sex" with genital inspections just to play sports. Opponents of the initiative say it's invasive, could block poorer students from getting verified, and could meet pushback from medical professionals who refuse to comply.

The initiative would require students who want to participate in girls' sports to provide "a health examination and consent form or other statement signed by the student's personal health care provider that verifies the student's biological sex, relying only on one or more of the following: The student's reproductive anatomy, genetic makeup, or normal endogenously produced testosterone levels."
