On Monday, a federal judge temporarily blocked President Trump’s proposed policy that would prevent transgendered people from serving in the military, according to The New York Times.

Judge Colleen Kollar-Kotelly from the U.S. District Court of the District of Columbia found the proposed policy to be unconstitutional.

As of June 2016, former President Obama announced transgendered servicemen and women would be able to serve openly and would no longer be turned away because of their identity, according to NPR.

In July 2017, President Trump posted a series of tweets announcing that transgendered Americans would no longer be allowed to serve in the military.

The administration later released an official memo that stated that as of Jan. 1, 2018, the military will go back to its policy before June 2016 that did not allow transgendered Americans to serve in the military.

The block placed on this policy will allow transgendered troops to re-enlist, and those who choose to enlist can do so freely starting in January. It won’t stop the restriction placed on sexual reassignment surgery, according to The New York Times.
