The text of a proposed Trump administration rule allowing homeless shelters to place transgender people by the gender assigned to them at birth includes instructions on how to identify transgender women, according to a report by Vox.

In the text of the proposed rule obtained by Vox, the Department of Housing and Urban Development (HUD) instructs shelters to consider, “factors such as height, the presence (but not the absence) of facial hair, the presence of an Adam’s apple, and other physical characteristics which, when considered together, are indicative of a person’s biological sex.”

The rule is a reversal of an Obama administration protection that required homeless shelters to house people according to their gender identity. While homeless shelters are still required to house transgender people, it is up to them how they choose to identify and place an individual, HUD announced on July 1, in an effort to "better accommodate religious beliefs of shelter providers."
