A transgender athlete, AB Hernandez, won two gold medals in California. Some people were not happy about this. Hernandez could play because of a new rule. This rule let another girl play and win if Hernandez did well. Some people protested because they do not want transgender athletes in girls' sports. The new rule was made because of Hernandez and a California law. But some people think the rule makes things confusing. Most adults in the US think transgender female athletes should not play in girls' sports.
