President Donald Trump released an order Friday night banning most transgender troops from serving in military except under “limited circumstances,” following up on his calls last year to ban transgender individuals from serving.

The White House said retaining troops with a history or diagnosis of “gender dysphoria” — those who may require substantial medical treatment — “presents considerable risk to military effectiveness and lethality.”…

“This new policy will enable the military to apply well-established mental and physical health standards — including those regarding the use of medical drugs — equally to all individuals who want to join and fight for the best military force the world has ever seen,” White House Press Secretary Sarah Huckabee Sanders said Friday.
