The Trump administration wants to erase transgender people from the law — with an explicit aim of ending the provision of gender-affirming medical care for trans people of all ages — and Solicitor General John Sauer asked the U.S. Supreme Court to usher in that world on Monday morning.

In a case over the provision of gender-affirming medical care and what’s referred to as “social accommodations” for trans people in prisons, the Justice Department on Monday asked the Supreme Court to block an order from U.S. District Judge Royce Lamberth that protected such care in the face of a new Federal Bureau of Prisons policy that would lead to the end of such care.
