Transgender Military Ban: Exclusion of Transgender Service Members via Tweet

Trump's tweet announcing the transgender military ban was not coordinated with military leadership. The Joint Chiefs issued an unusual public statement saying they would not change policy until they received 'formal guidance.' Multiple federal courts issued injunctions blocking the original ban. After losing court cases, the administration issued a modified 'Mattis plan' that imposed restrictions based on gender dysphoria treatment; it was implemented in 2019 and reversed by Biden in 2021. An estimated 14,700 transgender people were serving in the military.

Approximately 14,700 transgender service members whose military careers were disrupted or ended; transgender individuals who wished to serve who were barred
Alleged responsible parties
  • Donald Trump, President of the United States— White House

Key points

  • Trump announced the transgender ban on July 26, 2017 in a three-tweet announcement — without consulting the Joint Chiefs of Staff, who were reportedly blindsided
  • The Joint Chiefs issued an unusual public statement the same day: 'We will continue to treat all of our personnel with dignity and respect' — implicitly distancing military leadership from the announcement
  • The RAND Corporation had studied the issue and found the number of transgender service members likely to seek gender-related medical care was small (between 30-130 per year) and that open service would have 'minimal impact' on readiness and costs
  • Multiple federal district courts issued injunctions blocking the ban, finding it likely violated equal protection guarantees; the Supreme Court later stayed those injunctions, allowing a modified version to proceed
  • The modified 'Mattis plan' allowed transgender individuals to serve but barred those with gender dysphoria who required gender transition treatment; it was implemented in April 2019 after the Supreme Court stay
  • Biden reversed the policy on January 25, 2021 — his fifth day in office — reinstating the Obama-era policy of open service for transgender individuals

Overview

The announcement was made in three tweets.

There was no press conference, no policy document, no consultation with military leadership. The Joint Chiefs of Staff — the highest-ranking military officers in the country — learned about the policy change from Trump's Twitter account.

Their response was unprecedented in modern U.S. civil-military relations: a public statement that they would continue treating all personnel "with dignity and respect" and would await formal guidance before making any changes — implicitly declining to implement the policy announced by their commander-in-chief until they received proper orders.

What the Evidence Showed

The RAND Corporation had studied the question at the Defense Department's request during the Obama administration. Its findings: the number of transgender service members likely to seek transition-related medical care was between 30 and 130 per year. The impact on military readiness would be "minimal." The costs would be "small."

Trump's tweets cited "tremendous medical costs and disruption." The RAND analysis found neither.

Four different federal district courts issued injunctions blocking the ban, each finding that the policy likely violated the equal protection guarantees of the Constitution by discriminating based on gender identity without adequate justification. The legal question was not whether the government could set reasonable fitness standards — it could — but whether a categorical exclusion of all transgender individuals was permissible.

The Supreme Court, on a procedural basis, stayed the lower court injunctions without ruling on the merits. The modified version of the policy was implemented. Biden reversed it five days into his presidency.

Update log

  1. Updated with implementation of modified Mattis plan after Supreme Court stay.

Sequence of events

  1. Obama administration lifts transgender ban

    Defense Secretary Ash Carter announces the military will allow transgender individuals to serve openly, ending the previous exclusion policy. A one-year implementation period is established.

  2. Trump tweets ban — Joint Chiefs blindsided

    Trump announces in three tweets that transgender individuals will not be allowed to serve 'in any capacity.' The Joint Chiefs are reportedly not consulted in advance. They issue a statement indicating they will await formal guidance before changing any policies.

  3. Trump signs formal presidential memorandum

    Trump signs a formal presidential memorandum directing the military to return to pre-Obama transgender service policy, but gives Secretary Mattis authority to develop 'a study' with recommendations.

  4. Mattis plan submitted — modified ban

    Secretary Mattis submits a plan allowing transgender service members who are 'stable' (not in transition) to serve while barring those with gender dysphoria who require treatment. The plan is narrower than Trump's original tweet.

  5. Modified ban implemented after Supreme Court stay

    After the Supreme Court stays the lower court injunctions blocking the ban, the Mattis plan goes into effect. Transgender individuals with gender dysphoria who require transition are barred from new enlistment; current service members may be separated.

  6. Biden reverses ban on Day 5

    Biden signs an executive order on January 25, 2021, reversing the transgender military ban and reinstating the policy of open service for transgender individuals.

    Second-Term Transgender Military Ban: Day-One Executive Order

    The second-term ban was broader and more immediately disruptive than the first-term version. The 2025 executive order directed the Secretaries of Defense and Homeland Security to implement the policy within 60 days, mandating that transgender service members serve in their birth sex or face discharge. Service members who had been receiving hormone therapy and other gender-affirming medical care under a Biden-era policy would have that care immediately terminated. Legal challenges were filed immediately; courts issued preliminary injunctions in several cases. The policy applied to approximately 15,000 service members.

    First-Term LGBTQ Rollbacks: Transgender Military Ban, Healthcare Protections, Bathroom Guidance

    Trump's first executive actions on LGBTQ issues included rescinding a 2016 guidance protecting transgender students' bathroom access in public schools. In July 2017, Trump tweeted the military ban without notifying the Joint Chiefs; the tweet came after DOD had already been studying how to implement transgender service. The administration also reversed Obama-era healthcare anti-discrimination guidance, removed LGBTQ survey questions from the Census and government surveys, and reversed protections for LGBTQ workers in federal contracting. The Supreme Court ultimately ruled in June 2020 that Title VII's prohibition on sex discrimination covers LGBTQ workers.

    Travel Ban Expansions: From Muslim Ban to Permanent Entry Restrictions

    The travel ban evolved through three executive orders as earlier versions were blocked by courts for discriminatory purpose and due process violations. The third version added non-Muslim-majority countries to provide legal cover, and was upheld by the Supreme Court 5-4 in June 2018. The Court's majority expressly declined to consider Trump's public statements calling for a Muslim ban; Sotomayor's dissent quoted those statements at length and compared the ruling to Korematsu v. United States.

    George Floyd Protests: Lafayette Square Clearing, Militarized Response, Threat to Invoke Insurrection Act

    The clearing of Lafayette Square occurred approximately 30 minutes before the 7:00 PM curfew was to take effect. Independent investigators and journalists documented that the protesters were peaceful at the time of the clearing. The chemical agent used was later identified as a pepper chemical agent (technically not 'tear gas') deployed without warning. Trump had convened a call with governors the same day, calling them 'weak' and urging them to 'dominate' protesters. Attorney General Barr appeared in person to supervise the clearing. The Bible photo-op that followed was condemned by Episcopal Bishop Mariann Budde, whose church was used as a prop without her knowledge or consent.
