A US passport with an "X" gender designation

A passport belonging to Dana Zzyym rests on a table, Oct. 27, 2021, in Fort Collins, Colorado. Zzyym, who prefers a gender-neutral pronoun, told the Associated Press that their passport is the first US passport to be issued with an "X" gender designation, marking a milestone in the recognition of the rights of people who do not identify as male or female.
