AB Hernandez, a transgender athlete, won gold medals in high jump and triple jump at a California high school competition. This caused a lot of discussion and got attention across the country. Hernandez could compete because of a new rule in California. This rule allowed an extra girl to compete if Hernandez was good enough. Some people protested this, saying that transgender athletes should not play in women's sports. The new rule was made because of Hernandez's success and because California law says transgender students can play on teams that match their gender. But some people think this new rule makes things more confusing. Also, many adults in the US think transgender female athletes should not be allowed to play in girls' and women's sports.
