Caitlyn Jenner has been a problematic,???? ??? ?? ?? Donald Trump-loving spokeswoman for the transgender community. But that didn't stop her from coming out hard against the president Thursday night.

The transgender former-Olympian turned reality star isn't happy with Trump's reversal this week of an Obama-era action that allowed transgender kids to use the bathrooms of their choice in schools. In fact, she wants him to call her, stat.

Jenner has been swatting away critiques since she stumped for Republican candidates during the grueling 2016 election cycle. She said she wanted to be the trans ambassador for Ted Cruz and insisted that Trump would be a good candidate for women.

Well, she seems to have lost much of her goodwill towards the commander-in-chief when she recorded a candid message to Trump, speaking "from one Republican to another."

"This is a disaster, and you can still fix it," Jenner said. "You made a promise to protect the LGBTQ community. Call me."

In her Twitter message, which was a real departure from her previous endorsement of the GOP, Jenner condemned those who have lashed out against transgender people.

"I have a message for the trans kids of America — you're winning," Jenner said in her video. "I know it doesn't feel like it today or everyday, but, you're winning."

And she offered a not-so-subtle dig at Trump's new attorney general, Jeff Sessions.

"Now I have a message for the bullies," Jenner said. "You're sick. And because you're weak, you pick on kids, you pick on women, or anyone else you think is vulnerable. Apparently even becoming the Attorney General."

She pledged that these issues will be settled by the Supreme Court in the case of Gavin Grimm, who is fighting his Virginia school district over his bathroom rights. She also pointed to the National Center for Transgender Equality as a resource for those being discriminated based on their gender identity.

No word on whether Trump has taken up Jenner's offer yet, but her support stands out, nonetheless.
