Wyoming Gov. Mark Gordon (R) on Friday allowed legislation preventing transgender women and girls from competing on female sports teams to become law without his signature, making Wyoming the 19th state to enact such a law and the first to do so this year.

The new law, which will take effect July 1, restricts the ability of seventh- to 12th-grade transgender girls to participate on female sports teams. Some transgender students may be permitted to participate in interscholastic activities consistent with their gender identity if they receive approval from an eligibility panel.
