– Axios' Barak Ravid claims Marco Rubio ordered all U.S. embassies in the world to send an official diplomatic demarche onOperation Economic Outcast to "the most senior level" of their host governments.
A demarche is a formal diplomatic message that conveys a position, request, or protest. It's unclear what the demarches ordered by Rubio contain, but they're likely aimed at getting as many countries as possible on board with economic sanctions against Iran.
