WASHINGTON (AP) — Imprisoned national security leaker Chelsea Manning is renewing her demand in federal court to wear a feminine hairstyle.

The transgender former Army intelligence analyst filed the amended complaint Monday in U.S. District Court for the District of Columbia. It says gender-appropriate grooming is part of the recognized treatment for gender dysphoria, Manning’s sense of being a woman in a man’s body.

The military prison at Fort Leavenworth, Kansas began giving Manning hormone therapy in February, but officials there have refused to allow her to wear her hair longer than 2 inches. The military has cited “safety and security risks” for the decision.

The Army didn’t immediately respond to a request for comment on the filing.

Manning, formerly Bradley Manning, is serving 35 years for sending classified documents to the WikiLeaks website.
