Washington – The US military’s top officer directed military heads on Thursday not to implement any changes to current policy on transgender personnel, a day after President Donald Trump tweeted they would be banned from serving.

General Joe Dunford, who is Chairman of Joint Chiefs of Staff, said in a short memo to service heads and senior enlisted leaders that the current policy should remain in effect until Trump had given formal direction to the Pentagon and Defense Secretary Jim Mattis issues new guidance.

“In the meantime, we will continue to treat all of our personnel with respect,” Dunford wrote.

“As importantly, given the current fight and the challenges we face, we will remain focused on accomplishing our assigned missions.”

Transgender troops have been able to serve openly for more than a year, though a plan to allow them to sign up by July 1 was put on hold by Mattis.
