Former Donald Trump supporter and defender, Caitlyn Jenner, has taken issue with the president's latest executive decision to lift federal guidelines that said transgender students should be allowed to use public school bathrooms and locker rooms matching their chosen gender identity, in favor of state legislation on the issue.

Jenner tweeted a video addressing President Trump on Thursday evening, calling the decision a "disaster" and asking Trump to "call me."

"I have a message for the trans kids of America," Jenner says in the video. "You're winning. I know it doesn't feel like it today or every day, but you're winning."

Caitlyn Jenner, the transgender Olympic champion formerly known as Bruce, on Monday unveiled her new name and look in a sexy Vanity Fair cover shoot -- drawing widespread praise, including from the White House. Lesbian, gay, bisexual and transgender campaigners -- and many well-wishers -- welcomed the high-profile debut, as did the 65-year-old Jenner's family, which includes the media-savvy celebrity Kardashian clan. 'I'm so happy after such a long struggle to be living my true self,' Jenner wrote in her first tweet after the magazine released the July cover photo by renowned photographer Annie Leibovitz.

Jenner stressed that "bipartisan support" would be needed to "win full freedom nationwide." She then addressed the "bullies" who "pick on kids, pick on women and pick on anyone you think is vulnerable."

Jenner then called out attorney general Jeff Sessions, saying, "Apparently even becoming attorney general isn't enough to cure some people of their insecurities."

Finally, Jenner addressed Trump directly, "from one Republican to another." "This is a disaster, but you can still fix it," Jenner said. "You made a promise to protect the LGBTQ community. Call me."

Jenner came out publicly as transgender in 2015, and completed gender reassignment surgery that year.

Jenner is not the first to reach out to the president through social media since the decision was announced.

Singer Jackie Evancho, who performed at Trump's inauguration concert, pleaded with the president to "Pls give me & my sis the honor 2 meet with u 2 talk #transgender rghts." A number of high-profile stars also began tweeting and posting to social media to air their grievances with the Trump administration's decision.
