After expressing her excitement to sign a bill banning biological males from women’s sports, South Dakota Gov. Kristi Noem is wavering in her support for the legislation due to pressure from groups in South Dakota, The Daily Caller News Foundation has learned.

Noem, a Republican, said as recently as March 8 that she was “excited” to sign HB 1217, a bill that not only bans biological males from participating in women’s sports but also establishes that there are only two biological sexes (male and female) and that there are “inherent” differences between men and women.
