It occurs to me to wonder, how has this not yet generated a Trump tweet? It's an Army regulation that "Effective immediately, brigade-level commanders will be able to grant accommodations to servicemen and women who wear beards, turbans, or hijabs for religious reasons."
It seems tailor made for him: It's a tail end of the administration administrative order which changes past practice. It is an accommodation for a bunch of different minorities -- and in the US Army at that. So it will certainly offend a big chunk of his core constituents.
And yet there is, so far, silence. Maybe he just hasn't heard about it. Yet.
