Richard Grenell's supporters have already expressed dissatisfaction on social media: Why hasn't he received a position in the future Trump administration yet? The roles of foreign minister, Ukraine envoy and national security adviser, for which the former American ambassador in Berlin was being discussed, had long been taken. At the weekend, Donald Trump announced that he would appoint Grenell as envoy for special missions. In the future he will work in “some of the hottest places in the world”, such as Venezuela and North Korea.
