 Marshall introduced the "Physical Privacy Act" (HB 1612), a bill to restrict bathroom and changing facility use by transgender people in January 2017.The bill would have restricted the use of restrooms and changing facilities to the individual's sex, which the bill defined as the biological assignation at birth.In addition, the bill would have required public school principals to inform guardians of minors if the minor asked "to be recognized or treated as the opposite sex" within twenty-four hours of the request.
