The Presidential Memorandum on Military Service by Transgender Individuals, officially the Presidential Memorandum for the Secretary of Defense and the Secretary of Homeland Security, is the 27th presidential memorandum signed by U.S. President Donald Trump on August 25, 2017. The intent was to prevent transgender people from serving in the U.S. military, on the basis that they would be a financial burden due to sex reassignment procedures and associated costs. It did not exclude transgenders indiscriminately. Federal courts delayed the implementation of this rule by issuing four injunctions. On January 22, 2019, however, the U.S. Supreme Court allowed the Trump administration's ban to take effect.
