After the Department of Health and Human Services announced on Friday that it would scrap an Obama-era policy that expressly forbade health care providers from discriminating against transgender patients, advocacy groups and lawmakers alike began criticizing the move as damaging to a vulnerable group of Americans.

The pending change reverts regulations back to prohibiting discrimination solely based on sex, not gender identity. "When Congress prohibited sex discrimination, it did so according to the plain meaning of the term, and we are making our regulations conform," HHS Director of the Office for Civil Rights Roger Severino told The Washington Post.

Democrats who are running for president in 2020 wasted no time in decrying the Trump administration.

Sen. Kamala Harris (D-Calif.) pointed out another aspect of the HHS change: As Axios reports, the rolled-back nondiscrimination policy could also let adoption agencies reject same-sex couples, leaning on new religious exemptions.

The National Center for Transgender Equality has vowed to fight the proposed change — once the policy is rewritten it will surely face several legal challenges, something many 2020 Democrats suggested is necessary. Summer Meza
