Gov. Kristi Noem says she will sign legislation passed by the South Dakota legislature banning transgender athletes from participating in women’s and girls’ sports, becoming the latest state approving similar bills to outlaw such competition. “In South Dakota, we’re celebrating #InternationalWomensDay by defending women’s sports!,” Noem tweeted Monday, moments after the bill cleared the state Senate. “I’m excited to sign this bill very soon.” Backers of the bill say it promotes “fairness in women’s sports.” Republican Sen. Jim Bolin said he remembers track meets where the hurdles were raised after girls’ 100-meter races for boys’ heats. “That’s a clear illustration (of biological differences),” Bolin said, according to the Grand Forks Herald. But opponents said it will likely spark a series of legal battles.
