US President-elect Donald Trump is planning to ban transgender people from serving in the US military, The Times reported on Monday, citing defense sources. The plan reportedly entails Trump signing an executive order shortly after he takes office that would remove trans personnel already serving and prohibit such people from enlisting in the future.

About 15,000 active US service members are openly transgender. Those targeted would be discharged on medical grounds, deemed unfit to serve on the basis of their gender identification. It is unclear, however, whether they will have to undergo any examination to determine their trans status.

The new legislation is seen as a harsher version of the ban Trump passed during his first term in office. In 2018, he banned openly transgender people from joining the military, but allowed those already serving to keep their jobs. At the time, Trump claimed he had consulted with military experts and concluded that trans people should not serve in the army in “any capacity.” He stressed that allowing trans people into the ranks of the army comes with “tremendous medical costs,” as they allegedly require expensive hormone treatment.
