A lawsuit has been filed against Donald Trump's ban on transgender people serving in the military by five transgender service members.
A policy to permit transgender service had been given initial approval by the US Defense Department when Barack Obama was in power.
However this policy had allowed for a review in order to ensure the Pentagon had a firm plan for the assimiliation of trans people. The review was then extended by defense secretary James Mattis, before Trump stopped the policy entirely.
The ban has not yet come into force but attorneys for the service members are asking a federal court to block it.
The members have not been named but they claim to have cited current policy which allows them to serve, according to CNN. They also argue Trump's ban could mean their contracts are terminated or not renewed, and this would be unconstitutional.
The lawsuit also suggests that the White House has allowed tweets by the President to become official guidance, which is then usually approved.
The members say they have already told their commanding officers about being transgender and have already started treatment to change gender.
Their suit says they have now "lost the stability and certainty they had in their careers and benefits" yet have "served honourably and successfully in the military since coming out as transgender, and their transgender status has not had any detrimental effect on their ability to serve or to fulfill their duties."
