Caitlyn Jenner responded to Donald Trump's announcement on Wednesday that he plans to ban transgender military members from serving "in any capacity."
Jenner wrote on Twitter: "There are 15,000 patriotic transgender Americans in the US military fighting for all of us. What happened to your promise to fight for them?"

Jenner considers herself a transgender rights activist. The former Olympian has defended her support for Trump, saying that she as a Republican she supports him even if she doesn't always agree with his views.
While on The View recently, Jenner said she's been reaching out to members of Trump's administration to "help them" on LGBTQ issues. She said that she had hoped Trump would be a "bit more outspoken" in his support of the LGBTQ community he had promised to protect, but Jenner said she thinks "it's a lot of the people around him" who are affecting the president.
On July 16, Jenner reiterated to John Catsimatidis that she is trying to sway Republicans to improve their stances on LGBTQ rights. She also said that she is weighing a senatorial run. "Over the next six months or so I gotta find out where I can do a better job," Jenner said on the CATS radio show. "Can I do a better job from the outside working the perimeter of the political scene, being open to talking to anybody, or are you better off from the inside?"
When the Trump administration rescinded guidelines that protected transgender students' rights to use bathrooms based on their gender identity, Jenner made a video addressing Trump. "From one Republican to another, this is a disaster," she said. In a Diane Sawyer interview, she said, "I did vote for Trump, but here's the deal-breaker with the Republican party. And the deal-breaker is, you mess with my community, you do the wrong thing with our community, you don't give us equality and a fair shot, I'm coming after you."
A year ago, Jenner defended Trump as an LGBTQ supporter. "He seems very much behind the LGBT community because of what happened in North Carolina with the bathroom issue," she said. "He backed the LGBT community. But in Trump’s case, there’s a lot more unknowns. With Hillary, you pretty much know what you’re gonna get with the LGBT community.”
