Funny, when Obama was CINC he had unquestioned authority to dictate open bathrooms, gays, transgendered and those who refuse to identify as male or female.
Pres Trump makes a statement as CINC and it’s suddenly challenged.
Gays in the military was not an Obama EO, it was a vote of Congress.
It is not the President but Congress which makes rules for the government and regulation of the land and naval forces.
Questioned and countermanded by his own Secretary of Defense. And Trump remains dead silent while Mattis goes along his merry way with cross dressers, women in combat, and every other left wing social experiment for the military still firmly in place.
