The NCAA announced Thursday that it would change its rules to ban biological males from women’s sports, a day after President Donald Trump signed an executive order banning transgender athletes from women’s sports.

Trump’s order called on the federal government to bar transgender women – people who are biologically male – from competing in women’s sports, restricting the category to biological women only. A day after the president’s order, the NCAA Board of Governors voted to update its policy on transgender student-athletes, limiting women’s competitions only to include “student-athletes assigned female at birth only.”
