The American Civil Liberties Union is filing a lawsuit against the Trump Administration after the president’s directive to ban transgender military members from enlisting.

Five current transgender military members filed the suit, which argues that that the ban “violates the constitutional guarantees of equal protection and substantive due process by singling out transgender individuals for unequal and discriminatory treatment,” reports The Hollywood Reporter. 

It also argues that the ban “discriminates based on sex and transgender status and that the ban is based on uninformed speculation, myths and stereotypes, moral disapproval and a bare desire to harm this already vulnerable group.” Petty Officer First Class Brock Stone, Senior Airman John Doe, Airman First Class Seven Ero George, Petty Officer First Class Teagan Gilbert, and Technical Sergeant Tommie Parker are the plaintiffs named in the lawsuit.

Josh Block, senior staff attorney with the ACLU’S LGBT & HIV project, said in a statement: “Each and every claim made by the President Trump to justify this ban can be easily debunked by the conclusions drawn from the Department of Defense’s own review process. Allowing men and women who are transgender to serve openly and providing them with necessary health care does nothing to harm military readiness or unit cohesion. Men and women who are transgender with the courage and capacity to serve deserve more from their commander-in-chief.”
