Olympic gold medalist and transgender activist Caitlyn Jenner appealed to President Donald Trump on Thursday to discuss transgender rights with her, after the administration revoked landmark guidance to public schools to let transgender students use the bathrooms of their choice.

"I have a message for President Trump. From, well, one Republican to another, this is a disaster. And you can still fix it. You made a promise to protect the LGBTQ community. Call me," Jennersaid in a video posted on Twitter.

She encouraged supporters to contact LGBT rights group the National Center for Transgender Equality.

The Trump administration's action on Wednesday reversed a signature initiative of former president Barack Obama, whose Justice and Education departments had threatened to withhold funding for schools that did not comply with its guidance.
