Court documents referred to ACLU lawyer Chase Strangio, a biological female who identifies as a man and uses male pronouns, as "Mr."

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.

For Chase Strangio, the professional path that’s led to this moment – in which he’ll have 15 minutes to present an argument defending gender-affirming care for trans youth before the Supreme Court – cannot be unwoven from his life outside the courtroom.
