(BBC) The Obama administration has told schools to let transgender pupils use toilets matching their gender identity.
Attorney General Loretta Lynch said schools that don’t comply may face lawsuits or lose federal aid if they do not comply.
One senior Republican politician has condemned the move as the “beginning of the end” of the current school system.
In a separate move, the president also strengthened protections for LGBT people receiving health care.
The federal government is fighting the state of North Carolina in court over a law requiring people to use toilets according to their gender at birth.
However the Obama administration education and justice departments say public schools must respect transgender pupils’ gender identity even if their education records or identity documents indicate a different sex.
“There is no room in our schools for discrimination of any kind, including discrimination against transgender students on the basis of their sex,” Ms Lynch said.
