US President Donald Trump will reverse guidance predecessor Barack Obama gave to schools that transgender students should use toilets of their gender identity, the White House says.
Critics had called Mr Obama's guidance government overreach which threatened other students' privacy and safety.
White House spokesman Sean Spicer said Mr Trump firmly believed "this is a states' rights issue".
"I would expect further guidance to come out on that today," he told a news conference.
Though the Obama-era order will be rescinded, anti-bullying safeguards are expected to remain in place, the AP news agency reported, citing a government official.
Last May, Mr Obama's justice and education departments instructed public schools to allow transgender students to use whichever bathroom corresponded to their gender identity.
Though not legally binding, Mr Obama's order warned schools they could lose funding if they did not follow the new guidance.
The directive sparked backlash across the country, prompting legal challenges from 13 states and a Texas federal judge's preliminary injunction blocking the department's position in August.
The Obama administration's guidance was based on its interpretation of Title IX, the federal law that prohibits sex discrimination in education.
Mr Obama argued that protection extended to gender identity.
But Mr Spicer said the previous administration's guidelines were confusing and too difficult to implement.
