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.

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.

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

Hearing a high-profile culture-war clash, the Supreme Court on Wednesday seemed likely to uphold Tennessee’s ban on gender-affirming care 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.
