Secretary of Defense Pete Hegseth ordered the Pentagon to immediately start removing transgender troops from military service, in an internal memo issued Thursday, two days after the Supreme Court ruled that the Trump administration could begin enforcing the ban while litigation plays out in lower courts.

Under its new instructions, the Department of Defense will begin kicking out some 1,000 transgender service members and give others 30 days to identify themselves for removal. The memo directs active-duty transgender troops to voluntarily leave the military by June 6. Those in the National Guard and Reserves have until July 7.

“On conclusion of the self-identification eligibility window, the Military Departments will initiate involuntary separation processes,” the memo states.

The latest directive mirrors a similar memo that the department issued in February, but that action got held up by various lawsuits. Before a court ruling in March that halted the ban, about 1,000 transgender troops came forward.

The 1,000 troops who have already self-identified “will begin the voluntary separation process” from the military, Pentagon spokesman Sean Parnell said.

Until the deadlines, the Defense Department will begin reviewing medical records to identify those who have been diagnosed with gender dysphoria, show symptoms, or are being treated.

The Trump administration argues that troops suffering from gender dysphoria have no place in the military because they’re not mentally or physically prepared for the job.

“Expressing a false ‘gender identity’ divergent from an individual’s sex cannot satisfy the rigorous standards necessary for Military Service,” Thursday’s memo explains. “Service by individuals with a current diagnosis or history of, or exhibiting symptoms consistent with, gender dysphoria is not in the best interest of the Military Services and is not clearly consistent with the interests of national security.”

About 4,240 service members, or about 0.2 percent of the 2.1 million people in uniform, have been diagnosed with gender dysphoria, Defense Department data revealed in February. About half of the gender-dysphoric troops required no medical care, and about a quarter of them required surgery.

On Tuesday, the Supreme Court ruled in favor of the Trump administration. The brief order did not provide each justice’s reasoning, but it did show that the three liberal justices — Elena Kagan, Ketanji Brown Jackson, and Sonia Sotomayor — would have denied the emergency application.

Hegseth praised the ruling, declaring on social media: “No More Trans @ DoD.” Speaking at a conference hosted by U.S. Special Operations forces this week, Hegseth took a shot at the Biden-era Defense Department’s progressive agenda and suggested the new administration is going in the opposite direction.

“We are leaving wokeness and weakness behind,” the secretary said. “No more pronouns, no more climate change obsessions, no more emergency vaccine mandates, no more dudes in dresses. We are done with that sh**.”
