More than 160 members of Congress have filed a brief with the U.S. Supreme Court in support of defending transgender rights in America. The case, U.S. v. Skrmetti, set to be heard this fall, will determine the legality of Tennessee’s ban on gender-affirming healthcare fortransgender minors. This marks the first time the high court will address the constitutionality of such a ban, and its decision could have far-reaching implications for transgender rights across the United States.
