He says, "I grew up outside of New York, but I've known I've wanted move there for city's vibrant artistic community. As a trans person, I would hope that I'd be welcomed but many trans people aren't because we don't have the basic healthcare coverage we need to survive."

A representative from gay rights group GLAAD, which organised the PSA, adds, "Transgender healthcare isn't special healthcare. It's regular healthcare that non-trans people receive every day when they need it. Unfortunately, healthcare is often denied to trans people due to misinformation and bias. By repealing the exclusionary regulation, (politicians) can ensure that transgender people receiving Medicaid have the same access to essential care as anyone else."
