Today, the American Military Partner Association (AMPA), the nation’s largest organization of LGBT military families, responded to President Donald Trump’s tweets unilaterally reinstating a ban on all transgender service members, threatening the careers of thousands of currently serving troops.

“This is a horrifying, vicious attack on thousands of actively serving troops in the military who happen to be transgender,” said AMPA President Ashley Broadway-Mack. “Transgender service members are risking their lives around the world, and President Trump literally just put a target on their backs, threatening to ruin their careers and kick them out of the military. This is unconscionable, and we are beyond outraged.”

Since June 2016, it has been the policy of the Department of Defense to allow transgender members of the armed forces to serve openly and authentically. Estimates show there are more than 15,500 transgender individuals currently serving in the armed services. In addition to these service members, thousands of service members also have members of their families who are transgender.
