A single 15-minute argument in the middle of this week could change Chase Strangio’s life – and the lives of so many people like him in the United States. Strangio, an attorney for the ACLU, is set to make history Wednesday as the first known transgender person to argue before the US Supreme Court. And he’ll do it as part of the most high-profile dispute on the docket this session. The case, US v. Skrmetti, challenges a Tennessee law that bans treatments, including hormone therapy and puberty blockers, for transgender minors and imposes civil penalties on doctors who violate the prohibitions. Some two dozen similar laws have been enacted in recent years in Republican-led states.
