FILE - In this June 4, 2007, file photo, tennis champion Billie Jean King is introduced during a town hall conversation hosted by the group Women for Hillary in New York. King will not attend Friday's opening ceremony of the Sochi Olympics in Russia because her mother is ill. King, chosen in December to help lead the U.S. delegation to the Sochi Games, has been outspoken in her opposition to Russia's anti-gay law and had planned to attend ice hockey and figure skating events and meet U.S. athletes during her three-day visit to the games.
