The previous Trump administration effectively banned transgender people from joining, but the new memo says currently serving transgender troops will be discharged.

The Pentagon plans to kick out currently serving transgender service members who don’t meet specific requirements under its new policy, according to official guidance made public in a Wednesday court filing.

In a memo, the Pentagon said the U.S. will begin removing transgender troops from the military within 30 days unless they obtain a waiver on a case-by-case basis.
