(Lake Oswego, OR) -- The head track and field coach at Lake Oswego High School says he was fired for sending a letter about transgender athletes. John Parks tells KATU he sent a letter to the Oregon Schools Activities Association and State Senator Rob Wagner. He says transgender athletes should compete in their own division. Parks says he supports transgender athletes but doesn't think they should be able to compete against girls. The Lake Oswego School District says it doesn't release personnel information. Parks says he's appealing the termination.
