The NCAA, the governing body for US collegiate sports, has issued a new policy that limits competition in women's sports to only student-athletes assigned female at birth. Announced on Thursday, the National Collegiate Athletic Association said its policy applied to all athletes and was effective immediately.

The Education Department says it is investigating potential civil rights violations at two universities and a high school sports league that allowed transgender athletes to compete on women’s teams.

The decision, effective immediately, came a day after President Trump signed an order barring transgender girls and women from playing in women’s sports at federally funded educational institutions.
