Caitlyn Jenner has issued a message directly to US President Donald Trump over the revoking of transgender protections, telling him the move is "a disaster".
The Keeping Up with the Kardashians star is disappointed rules introduced by Barack Obama are being removed, meaning schools may force students to use a toilet that doesn't correspond with their gender identity.
Jenner, who supported Mr Trump during the presidential campaign last year, has published a video online chastising him for allowing the change.
"I have a message for President Trump, from one Republican to another," says Jenner.
"This is a disaster. And you can still fix it. You made a promise to protect the LGBTQ community. Call me."
In 2016, Mr Trump said North Carolina's so-called 'bathroom law' - which directs transgender people to use the bathroom that matches the gender on their birth certificates - had caused unnecessary strife.
Jenner posted a video last April of her using a female toilet in a Trump Tower, seeming to prove that the former Celebrity Apprentice host had no problem with people using whichever toilet they wished to.
"Thank you to the LGBT community!" Trump later tweeted.
"I will fight for you while Hillary brings in more people that will threaten your freedoms and beliefs."
Also in her new video, Jenner sends a message of hope to other transgender people - and a stern message to those preying on them.
"Very soon [the transgender community] will win full freedom nationwide and it's going to be with bi-partisan support," Jenner said.
"Now I have a message for the bullies: You're sick. Because you're weak, you pick on kids, you pick on women or anyone else you think is vulnerable."
Mr Trump is yet to respond to Jenner.
