An attorney poised to become the first transgender person to argue before the Supreme Court suggested that Vice President Kamala Harris does not “give a s*** about trans people,” according to recent posts on social media.

The Supreme Court on Monday agreed to allow Chase Strangio, co-director of the American Civil Liberties Union‘s LGBTQ and HIV Project, to argue in early December on behalf of the families of three minors in Tennessee who challenged the state’s cross-sex hormone ban for patients under 18. The case is expected to be one of the highest-profile of the Supreme Court’s term.
