Senate Democrats on Wednesday excluded the mother of a female student-athlete from testifying about the adverse effects of the Equality Act on fairness in women’s sports.

The students, Chelsea Mitchell, Alanna Smith, and Selina Soule, were asked by Senate Republicans to relay their experiences as biological females competing against transgender athletes in high school sports. Mitchell’s mother, Christina Mitchell, was asked to testify. All of them, who are also involved in a Connecticut lawsuit over the issue, were denied a speaking slot by Senate Judiciary Chairman Dick Durbin.
