Yesterday President Biden issued an Executive Order (full text) reversing the Trump Administration's 2018 transgender military service ban. In his remarks at the signing of the Executive Order, President Biden said in part:
this is reinstating a position that previous commanders and — as well as the Secretaries have supported. And what I’m doing is enabling all qualified Americans to serve their country in uniform, and essentially restoring the situation as it existed before, with transgender personnel, if qualified in every other way, can serve their government in the United States military.
