U.S. moves to remove transgender troops from military, Pentagon memo shows

Driving the news: The Trump administration was responding on Wednesday to a lawsuit filed in D.C. on behalf of six transgender service members who are challenging the legality of President Trump's January executive order targeting transgender troops.

• The suit contends the order that states that the federal government will recognize only two sexes, male and female, and which calls on the Pentagon to formulate a policy that would target transgender service members is unconstitutional.

Zoom in: "Service members who have a current diagnosis or history of, or exhibit symptoms consistent with, gender dysphoria will be processed for separation from military service," states the policy, which echoes language similar to that used in Trump's order.

• Service members who seek to obtain a waiver must show they never tried to transition, according to the Pentagon.
• They must also demonstrate "36 consecutive months of stability in the Service member's sex without clinically significant distress or impairment in social, occupational, or other important areas of functioning."

Between the lines: Gender dysphoria is defined as distress related to gender incongruence.

• The number of transgender people serving on active duty in the military was estimated to be up to 8,000, per a 2020 study published by the NIH that notes the actual number may be greater due to factors including fear of disclosure.

Flashback: Trump rescinded on his first day in office a policy allowing trans people to serve, implemented by his predecessor, former President Biden.
