The Supreme Court on Thursday agreed to decide whether states may ban transgender students from playing on sports teams that align with their gender identity, revisiting the issue of LGBTQ rights in a blockbuster case just days after upholding a ban on some health care for trans youth.

Republican President Donald Trump also has acted aggressively in other areas involving transgender people, including removing transgender troops from military service. In May, the Supreme Court allowed the ouster of transgender service members to proceed, reversing lower courts that had blocked it.
