On Wednesday morning, a Nashville teenager and her parents filed into the U.S. Supreme Court along with Tennessee Gov. Bill Lee and ranking Republican lawmakers. They filled its wooden benches as the nation's top justices heard arguments in a case that could have wide-reaching impacts across the country.

The Supreme Court will hear oral arguments Wednesday over Tennessee’s ban on gender-affirming care for minors, a landmark case that will have implications nationwide as Republicans have increasingly targeted transgender rights and enacted bans on healthcare for minors across the country.
