President Donald Trump signed an Executive Order on Tuesday banning federal funding to hospitals, clinics, and other medical organizations that provide gender-affirming care to transgender kids under age 19. According to The 19th, the Order could effectively ban gender-affirming care for trans youth across the country.

Trans people in federal custody are already feeling immediate impacts of the order, the ACLU’s Gillian Branstetter says.

One of the women sued the Trump administration, alleging the order violates her constitutional rights and puts her “at an extremely high risk of harassment, abuse, violence, and sexual assault.”
