Chelsea Manning, the former Army intelligence analyst who is serving a 35-year sentence for leaking diplomatic and military documents to WikiLeaks, has had a tough run: She’s already served more time behind bars than any other whistleblower in history; she was held in solitary confinement for 11 months before her trial, which she likened to torture; and it took Army officials nearly 18 months after she sought treatment for gender dysphoria to approve her for hormone treatments, but she is still required to conform to male military dress standards.

The military’s decision in September 2016 to allow her to receive gender confirmation surgery, as part of its broader policy change that allowed transgender service-members to serve openly and receive coverage of their medical care, was a bright spot in a year for Manning that included two suicide attempts and, as punishment, another stint in solitary confinement.

That bright spot, however, may be dimming as a result of the election of Donald Trump. The president-elect pledged in October to review the military’s new policy on transgender service-members, calling it a dangerous act of political correctness. The man he nominated to be his national security advisor, Lt. Gen. Michael Flynn, alluded to the policy during his speech at the Republican National Convention in July, suggesting that it was distracting the troops from their mission.

With the transition team openly determining what executive orders and departmental guidances they can rescind in the first 100 days and beyond, there’s every likelihood that the incoming administration is considering revising President Barack Obama’s military transgender policy—which would deny Manning the opportunity to have the surgery she desires. (The Trump transition team and Trump’s spokeswoman, Hope Hicks, did not return requests for comment.)

“I think that there’s a lot of reason to be concerned about what is going to happen moving forward,” said Chase Strangio, a staff attorney with the ACLU who has represented Manning. “They could reinstate the ban on open trans service right away.”
