On Wednesday, the Trump administration reversed a directive issued in May 2016 by former President Barack Obama, which said transgender students should be allowed to use bathrooms and locker rooms at public schools that match their gender identity if it differs from their birth sex.

Obama's guidance was not legally binding, but advocates said it was needed to protect transgender students from being discriminated against. The Justice and Education departments sent letters to schools on Wednesday saying the earlier directive led to confusion and lawsuits, but anti-bullying measures won't be affected. Now, states and school districts will decide if federal anti-discrimination laws apply to gender identity.
