The Supreme Court hears oral arguments on the ability of states to restrict treatments for minors whose gender identity doesn't align with their sex assigned at birth.

Chase Strangio made history Wednesday when he became the first openly trans attorney to argue before the US Supreme Court. An attorney with the American Civil Liberties Union, Strangio argued against a Tennessee law denying gender-affirming care for minors.

Justice Samuel Alito grilled ACLU attorney Chase Strangio, the first-ever openly trans attorney to present at the high court, to repeatedly cast doubt on whether being transgender is “immutable” and thus protected by anti-discrimination laws.

The Biden administration’s top Supreme Court lawyer warned a decision favorable to Tennessee also could be used to justify nationwide restrictions on transgender healthcare for minors.

At least 26 states have adopted laws restricting or banning such care for minors, and most of those states face lawsuits.

Chase Strangio will be the first openly transgender attorney to argue before the nation's highest court, representing families who say Tennessee’s ban on health care for transgender minors leaves their children terrified about the future.
