The new directive comes after an adopted recommendation from defence secretary Jim Mattis, who said '"transgender persons who require or have undergone gender transition" can not serve in the military.
"What the White House has released tonight is transphobia masquerading as policy", Joshua Block, a senior staff lawyer at the American Civil Liberties Union LGBT and HIV Project, said in a statement.
"The Trump-Pence administration's continued insistence on targeting our military families for discrimination is appalling, reckless, and unpatriotic", added American Military Partner Association president Ashley Broadway-Mack. The new policy must first be published in the Federal Register, which generally requires new rules to be reviewed and subject to a public comment period before they are enacted. "We are calling this what it is - an attempt to legitimize an unwarranted and unnecessary attack that targets individuals who have volunteered their lives in support of this country", said Matt Thorn, president of OutServe-SLDN.
The ban has since been battled over in court, with Mattis in February giving Trump a final recommendation.
On Friday night, hours after another tumultuous week wrapped up in Washington, the Trump administration issued a vaguely-worded memo that would bar transgender people from serving in the military, while giving the Pentagon some discretion over how the policy is carried out. Accordingly, transgender troops now serving may continue to do so, however, the Pentagon has the option to "require them to serve according to the gender at birth".
The president signed on Friday a memorandum, veto, which has been frozen in the courts since last December, but refers to a new policy recommended by the Pentagon that also represents a serious blow to the weakest link in the country, the LGTB community. "Transgender people in our military deserve more from their government than a myth-driven proclamation about their unfitness for full civic inclusion".
The ban comes as "five-time draft dodger", Trump termed transgender people a liability effecting the "lethality" of the military.
On Friday, the Pentagon reaffirmed that it would continue to comply with federal law. In addition, the RAND study, on which the Obama administration based its policies, found that there were no adverse effects on military readiness after the acceptance of openly transgender troops in Australia, Canada, Israel, and the United Kingdom. David Eastburn, a Pentagon spokesman.
However, just because this ban might hold up a little better in court, that doesn't mean it's any less transphobic-and that doesn't mean Trump is any less obviously using an official diagnosis of gender dysphoria as a smokescreen to effectively ban all trans people.
"Until the day we as transgender service members are ordered to take off our uniform, we will press forward and continue our commitments". "The Department of Justice will continue to defend DOD's lawful authority to create and implement personnel policies they have determined are necessary to best defend our nation".
