The federal government will only recognize two sexes, male and female, under an executive order that President Donald Trump signed Monday.

President Donald Trump has delivered a series of executive orders after being sworn into office, one of which declared that the US government will recognise “only two genders, male and female”. The White House has now suggested that the executive order will remove the “X” gender marker on passports and other government-issued IDs for trans and non-binary people in the US.

Like many of his other "Day 1" decrees, the order seems more concerned with scoring points in the culture war than advancing sensible policy.
