Trump announced in an August memo that he intended to reverse course on a 2016 policy that allowed troops to serve openly as transgender individuals. He said he would order a return to the policy prior to June 2016, under which service members could be discharged for being transgender.
U.S. District Judge Colleen Kollar-Kotelly wrote Monday that transgender members of the military who had sued over the change were likely to win their lawsuit and barred the Trump administration from reversing course.
