The message comes a year after Trump let the former Olympic hero use a bathroom of her choice at Trump Tower.
Caitlyn Jenner has unloaded on President Trump following his administration's decision to scrap the federal transgender bathroom directive.

The Olympic hero took to Twitter Thursday, posting a video blasting Trump, who she publicly supported during his campaign for the White House.
“Finally, I have a message for Mr. Trump from one Republican to another, this is a disaster," she tweeted. "You made a promise to protect the LGBTQ community. Call me."

At one point during the 2016 campaign, Jenner poked fun at former Republican presidential candidate Ted Cruz, who backed North Carolina’s passing of its HB2 Bill, which forbids transgender people from using the restrooms coinciding with the gender they identify with.
Trump invited Jenner to use any bathroom she wanted at Trump Tower and the former Olympian took him up on the offer.
In a tongue-in-cheek video, Jenner created a video called "Bathroom Break" and said: “Donald Trump told me I could take a pee anywhere at a Trump facility so I'm gonna go to the ladies' room.'"
In the video, she walked past the men’s room and joked: "Not anymore."
When Jenner emerged from the restroom in her video, she took a swipe at Cruz, saying, “And by the way, Ted, nobody got molested."
