"I’ve had things thrown at me. I’ve had people say pretty horrible things and the unsafe environment is just very unhealthy so I feel like Donald Trump needs to know that being in such an unsafe environment won’t do any good not only for the transgenders and the LGBTQ community but as well as everyone as a whole.""When I heard about it I was very disappointed and I realized that we would need to take action in order to enlighten the administration on everything," she said.
