Kristi Noem introducing women's sports bill limiting participation based on sex on birth certificate

South Dakota Gov. Kristi Noem plans to introduce women's sports legislation that would restrict participation based on the sex identified on an athlete's birth certificate.

Expected Tuesday, the bill would make good on a promise Noem delivered when she controversially vetoed a similar bill from the state legislature. It also raises questions about her previous objection to the state legislature's restrictions on participation at the collegiate level.

Noem had argued that unlike elementary and secondary school regulations, collegiate restrictions would create an unworkable patchwork for athletic organizations that operate at the national level. Nonetheless, she signed an executive order at the time stating that the board of regents "should" restrict participation in women's sports – omitting the type of binding language she utilized in another order for the state's department of education.
