“The governor has been clear – hate has no place in Pennsylvania, and that includes discrimination. Any legislation designed to deny opportunities to certain children is both disturbing and dangerous. Trans youth should know that they belong, that they are valued, and that their participation in school activities is welcomed. The governor would veto this type of legislation.”
