Marine General Joseph Dunford, chairman of the Joint Chiefs of Staff, has said that despite what Donald Trump tweeted, there will be no change to the military's current transgender policy until the President's directive has been received by the Secretary of Defense.

"There will be no modifications to the current policy until the President's direction has been received by the Secretary of Defense and the Secretary has issued implementation guidance," Dunford said in a message to military leaders seen by Reuters.

"In the meantime, we will continue to treat all of our personnel with respect. As importantly, given the current fight and the challenges we face, we will all remain focused on accomplishing our assigned missions," the note continued.

Trump tweeted on Wednesday morning that the U.S. military would not allow transgender people to serve in any capacity. He claims the military "cannot be burdened with the tremendous medical costs and disruption transgender in the military would entail."
