According to Governor Noem the first bill had flaws in it that would allow the NCAA to sue South Dakota. She issued executive orders to protect girls from having biological men play in girl's sports until they fixed the flaws in the bill. Then she signed the new bill which is supposedly one of the strongest bills in the nation protecting women in sports.
I do not trust Noem because when she was in the House of Representatives I saw a picture of her appearing to be close friends with disgraced rep. (and closeted homo) Aaaron Schock. The picture told me everything I needed to know. She’s part of the ‘club’ that doesn’t want Trump in it.
