The Trump administration said Monday that the University of Pennsylvania violated laws guaranteeing women equal opportunities in athletics by letting a transgender swimmer compete on the school's women's team and into team facilities.

The Department of Education has given UPenn ten days to wipe out any records set by trans people, issue a formal apology, and agree to ban trans athletes going forward.

The lawsuit sets the stage for another legal battle over the issue after the government sued Maine for its refusal to ban trans athletes.
