A transgender employee at the US National Security Agency (NSA) sued the Trump administration on Monday, alleging discrimination on the basis of gender identity.

Sarah O’Neill, a data scientist at the agency, filed a complaint in the District Court for the District of Maryland against William Hartman, acting director of the NSA. The complaint asserts that the NSA created a hostile work environment against O’Neill by prohibiting her from using women’s restrooms. This followed the cancellation of NSA Policy 1-73, which had permitted employees to use restrooms aligning with their gender identity. It further pointed to the amendment of NSA Policy 6-33, to prohibit signing off emails with pronouns that do not align with the sender’s biological sex. These policy decisions complied with Executive Order 14168, which declared in January that it is US policy to “recognize two sexes, male and female” and to remove “internal and external messages that promote or otherwise inculcate gender ideology.” O’Neill argues that these federal policy decisions “denigrate her identity” and threaten her wellbeing.

The complaint alleged that these policies violate Title VII of the Civil Rights Act of 1964, which prohibits discrimination on the basis of sex in federal personnel decisions. The complaint cited the 2019 Supreme Court case Bostock v. Clayton County to argue that this extends to gender identity, and that policies creating a hostile work environment on the basis of gender identity therefore constitute unlawful discrimination.

The Trump administration has yet to comment on the lawsuit. Trump banned transgender people from serving in the military in both his first and second terms. Defense Secretary Pete Hegseth ordered the removal of “all traces of gender ideology” from the Department of Defense to comply with Executive Order 14168 in January.

O’Neill is seeking monetary damages and declaratory relief.
