The U.S. Olympic and Paralympic Committee has effectively barred transgender women from competing in women's sports, telling sports governing bodies it has an "obligation to comply" with federal policy.

USOPC's previous policy had said transgender participation should be based on 'fairness' and 'science-based evidence rather than ideology.'

The policy update doesn't use the word "transgender," but it says it will comply with President Donald Trump's executive order on the matter.
