A federal judge in Seattle has ordered President Donald Trump not to take any action barring transgender troops from serving in the military, finding that it's unclear whether recent tweaks to his administration's policy are constitutional. In an order Friday, April 13, 2018, U.S. District Judge Marsha Pechman said that because the tweaks were announced just last month, the parties had not had time to argue about whether the policy is unconstitutionally discriminatory or whether the military is entitled to deference.

A U.S. judge in Seattle has ordered President Donald Trump not to ban transgender troops from serving in the military, saying it’s unclear whether recent changes to his administration’s policy are constitutional.

U.S. District Judge Marsha Pechman was one of four judges nationwide who blocked Trump late last year from overturning an Obama-era directive allowing transgender troops to serve openly.
