The Pentagon will immediately begin moving as many as 1,000 openly identifying transgender service members out of the military and give others 30 days to self-identify.

The Pentagon's ban is just one of a series of steps the Trump administration has taken to curb transgender rights. Trump issued an executive order on his first day in office on January 20 stating that the U.S. government will recognize only two sexes, male and female, and that they are not changeable.
