The athletes, coaches, lawmakers and officials who have picked a side in the SCOTUS women's sports battle

Former Deputy Assistant Attorney General John Yoo joins 'Saturday in America' to weigh in on the fight for fairness in women's sports as the Supreme Court is set to hear cases involving transgender athletes.

With the U.S. Supreme Court set to rule on two cases focused on the issue of biological males in women's sports, hundreds of prominent figures in sports and politics have publicly taken a side. 

At least 77 amicus briefs have been filed for the upcoming court review, some in support of the trans athlete plaintiffs and some in support of the "save women's sports" defendants. Famed athletes, coaches, U.S. lawmakers and other state and federal government officials have signed onto those briefs, declaring their allegiance in the historic legal battle.
