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

In February, Trump signed an executive order barring trans athletes from playing girls and women’s sports. Minnesota Attorney General Keith Ellison issued a formal legal opinion that states barring trans athlete participation would violate the Minnesota Human Rights Act, which supersedes Trump’s executive order.

Democratic Minnesota Attorney General Keith Ellison has filed a preemptive lawsuit against Republican President Donald Trump over the administration's push to ban transgender athletes from girls and women's sports.
