Today, the President rescinded his previous memorandum on transgender service in the military in order to allow Secretary Mattis to implement a new policy developed through extensive study by senior uniformed and civilian leaders, including combat veterans. The experts’ study sets forth a policy to enhance our military’s readiness, lethality, and effectiveness. On the advice of these experts, the Secretary of Defense and the Secretary of Homeland Security have concluded that the accession or retention of individuals with a history or diagnosis of gender dysphoria—those who may require substantial medical treatment, including through medical drugs or surgery—presents considerable risk to military effectiveness and lethality. This new policy will enable the military to apply well-established mental and physical health standards—including those regarding the use of medical drugs—equally to all individuals who want to join and fight for the best military force the world has ever seen. The Secretary of Defense’s memorandum and accompanying report have been made public today.
