>For the first time since the idea reached the Iowa Legislature, a measure that would require transgender people in Iowa schools to use bathrooms that correspond to the sex listed on their birth certificates won a subcommittee vote in the Iowa Senate. >The measure, Senate File 224, would apply to people using bathrooms in elementary and secondary public and nonpublic schools. It passed a Senate education subcommittee meeting Wednesday, with Sens. Jim Carlin, R-Sioux City, and Jeff Taylor, R-Sioux Center, supporting it and Sen. Claire Celsi, D-West Des Moines, opposed. It is now eligible for consideration by the full Senate Education Committee. >Other so-called bathroom bills have been introduced in Iowa over the past several years, but Wednesday was the first time that one of those bills has even received a subcommittee hearing, said Keenan Crow, policy and advocacy director for the LGBTQ advocacy group One Iowa. >A subcommittee is the first time in the legislative process that a group of lawmakers considers a bill. The subcommittee stage gives members of the public their only opportunity to weigh in directly to lawmakers for or against legislation. >Bathroom bills have also appeared in state legislatures around the country, most prominently in North Carolina, which passed its bill into law in 2016. The North Carolina law sparked a massive backlash as businesses, celebrities and others denounced the law and groups like the NBA and NCAA moved major events out of the state in protest. Lawmakers passed a partial repeal of that law a year later.
