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.
