Trump's executive order takes aim at the use of puberty blockers, sex hormones and surgical intervention on children and teens under age 19 who want their physical appearance to align with a sex that differs from the one they were assigned at birth.

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.
