A Florida bill would ban Transgender women and girls from playing on girls’ and women’s school sports teams. The bill was passed by a Florida House committee on Wednesday.

The Fairness in Women’s Sports Act, would require that anyone participating in girls’ and women’s sports at the K-12 and college level be biologically eligible to do so. If challenged, they would have to get confirmation from a health care provider that they are female. That could include a doctor examining their genitals.

While Republican in Congress are supportive of the bill, Democrats are against the proposal, calling it discriminatory against transgender girls and women.

The House Secondary Education & Career Development Subcommittee voted 13-4 to approve the bill, with all “no” votes cast by Democrats.

The Florida bill has two more committee stops in the House. A similar Senate bill hasn’t received its first hearing.
