Fox News contributor Erick Erickson attacked transgender military members as “mentally ill” in response to the Pentagon's landmark announcement that the Department of Defense will create a working group to review “policy and readiness implications of welcoming transgender persons to serve openly.” 

On July 13, a press release from Secretary of Defense Carter Ash stated that the military's current ban on transgender service members is outdated and going forward, “must treat all our people with the dignity and respect they deserve”:

The Defense Department's current regulations regarding transgender service members are outdated and are causing uncertainty that distracts commanders from our core missions. At a time when our troops have learned from experience that the most important qualification for service members should be whether they're able and willing to do their job, our officers and enlisted personnel are faced with certain rules that tell them the opposite. Moreover, we have transgender soldiers, sailors, airmen, and Marines - real, patriotic Americans - who I know are being hurt by an outdated, confusing, inconsistent approach that's contrary to our value of service and individual merit.

Today, I am issuing two directives to deal with this matter. First, DoD will create a working group to study over the next six months the policy and readiness implications of welcoming transgender persons to serve openly. Led by (Acting) Under Secretary of Defense for Personnel and Readiness Brad Carson, and composed of military and civilian personnel representing all the military services and the Joint Staff, this working group will report to Deputy Secretary of Defense Bob Work. At my direction, the working group will start with the presumption that transgender persons can serve openly without adverse impact on military effectiveness and readiness, unless and except where objective, practical impediments are identified. Second, I am directing that decision authority in all administrative discharges for those diagnosed with gender dysphoria or who identify themselves as transgender be elevated to Under Secretary Carson, who will make determinations on all potential separations.

After this announcement, Erickson responded on Twitter that transgender individuals, specifically those serving in the military, are “mentally ill”:

It is very kind of the Obama administration to allow the mentally ill to serve openly in the military.

In its report on this news, Time cited a report from the Williams Institute at UCLA that estimated 15,500 transgender individuals currently serve in the U.S. military.
