The presidential memorandum also bans the Department of Defense from using its resources to provide medical treatment regimens for transgender individuals currently serving in the military.

Trump also directed the departments of Defense and Homeland Security “to determine how to address transgender individuals currently serving based on military effectiveness and lethality, unitary cohesion, budgetary constraints, applicable law, and all factors that may be relevant,” the White House official said.

The White House official who briefed reporters on the memo on Friday evening declined to say whether current transgender troops would be allowed to remain in the military under those policy guidelines.
