Riley Gaines, a former top college athlete, called on Congress on Wednesday to pass the “Women’s Bill of Rights,” which would clarify that the term “woman” is based on biology rather than personal identity when it appears in federal law.

The bill, led by Rep. Debbie Lesko (R-AZ) and cosponsored by about two dozen other Republicans, would codify the meanings of several of these sex-based terms, including “sex,” “woman,” “man,” “girl,” “boy,” “mother,” and “father.”

“This is crucial to ensure that women, we’re entitled to our privacy and our safety and our fairness and our equal opportunity,” Gaines said, adding, “I’m speaking for so much more than just myself.”
