A federal court on Monday blocked parts of President Trump’s ban on transgender service members, preventing the Pentagon from overturning policies initiated by the Obama administration to allow transgender troops from serving openly.

The order in Washington by U.S. District Judge Colleen Kollar-Kotelly temporarily prevents to the Pentagon from enacting the ban that Trump announced by tweet in July.

The court found that the ban likely means the plaintiffs — transgender troops some with decades or meritorious service – had their rights to due process violated.
