Defense Secretary Jim Mattis is leaving an Obama-era policy on transgender military service members largely intact, saying he needs input from an expert panel to determine the best way to implement President Trump’s ban that would keep transgender people from serving in the U.S. military.

Trump barred transgender would-be recruits from signing up, but he gave Mattis discretion to decide the status of transgender people who are already serving.

Mattis says he’ll convene the panel from the Department of Defense and the Department of Homeland Security, with the goal of promoting “military readiness, lethality, and unit cohesion” — while also following legal and budgetary constraints. Mike Malloy discusses this.
