U.S. Attorney General Pam Bondi on Wednesday was due to unveil legal action against Maine, in an escalation of President Donald Trump's conflict with the state for refusing to ban transgender athletes from participating in women's and girls' sports.

The Trump administration said Wednesday it is suing Maine’s education department for not complying with the government's push to ban transgender athletes in girls sports, escalating a dispute over whether the state is abiding by a federal law that bars discrimination in education based on sex.
