Defining “transgender” out of existence

The Trump administration is considering classifying gender as determined by genitalia at birth, part of a governmentwide effort to roll back recognition of transgender people under federal civil rights law.

The Times obtained a draft memo from the Department of Health and Human Services that would define sex as either male or female, and unchangeable.
