The Trump administration is working on a new set of directives on the use of school bathrooms by transgender students, the White House said Tuesday.

The announcement alarmed LGBT groups across the country that have urged President Donald Trump to safeguard Obama-era guidelines allowing students to use school restrooms that match their gender identity, not their assigned gender at birth.

White House spokesman Sean Spicer did not provide any details on the new guidelines that are being prepared by the Justice Department, but said Trump has long held that such matters should be left to the states, not the federal government, to decide.

The Obama administration's guidance, issued last May, held that transgender students can access restrooms and participate in school athletics according with the gender they identify with.

Schools were also instructed to treat students in line with their expressed gender identity without requiring any medical proof.

While the move was hailed by rights organizations, it was attacked by conservative groups, which called it federal overreach and an infringement on the personal space and safety of all other students.

A patchwork of state laws and policies on the issue is emerging.

Fifteen states have explicit protections for transgender students, and many individual school districts in other states have adopted policies that recognize students on the basis of their gender identity, said Sarah Warbelow, legal director of the Human Rights Campaign. Just one state, North Carolina, has enacted a law restricting students' bathroom access to their sex at birth.

But so far this year, lawmakers in more than 10 states are considering similar legislation, according to the National Conference of State Legislators.

"Just, my stomach feels cold with worry. Even walking out, I saw a large group of school kids leaving the North Carolina General Assembly and wondered, How many students who are trans or gender non-conforming in that class might be hearing that same message today, and feeling like it's less for them in school. And that makes me, that makes me feel really sad as a trans person. To think about a young person feeling a lack of hope because of what the folks in this building and in Washington, DC are doing."

"When Congress passed the Civil Rights Act and Title IX, they never contemplated that sex would mean gender identity. It's not in the bill. It's not what the bill says. It's not what the law says. And so we think that the directive that the Obama administration issued about interpreting sex as meaning gender identity is wrong, and it should be repealed."

"We believe that this is a terrible message that the Trump administration is sending to some of the most vulnerable young people in our country today. That the president and the administration are not going to protect them from discrimination, no matter what Title IX says."
