NEW YORK (AP) — Billie Jean King’s victory in the “Battle of the Sexes” was a milestone moment as women pushed for equality on the playing field and beyond. On the 50th anniversary of that match against Bobby Riggs — still the most-watched in tennis history — King will move toward becoming the first female individual athlete to be awarded the Congressional Gold Medal. Three U.S. senators will introduce a bill Wednesday that would award the honor to King, the tennis Hall of Famer and activist who was a driving force behind the creation of the women’s pro tour and equal prize money for men and women.
