The Trump administration has scrapped an Obama directive aimed at protecting the rights of transgender students, telling schools in a guidance letter on Wednesday night that the policy has caused a rash of litigation nationwide and needs to be reconsidered.The Justice and Education departments said in their two-page guidance letter to schools that the Obama administration’s interpretation of federal law, allowing transgender students to use bathrooms and locker rooms in alignment with their gender identity, “has given rise to significant litigation.”“In addition, the Departments believe that, in this context, there must be due regard for the primary role of the States and local school districts in establishing educational policy,” the letter says.
