The complete tosh gurgitated by our down-south acquaintance begs the question you asked, Julian. "Directment" doesn't exist in dictionary.com - the only dictionary I currently have access to. And although I can't check at the moment, I'm willing to bet that if it does exist in a dictionary somewhere, perhaps, for instance, the much-boosted OED, it won't mean what it appears to be meant to mean in the statement you quoted.
However since it emanated from the US government, it's a safe bet that one of the US president's equally ill-educated minions came up with it when s/he couldn't come up with "proponent" or "supporter" or some synonym of them.
Coining new words is only justified when there isn't a word which exactly means what you want to say. Except swear-words of course, and this [i[could be one those, of course.
Welcome, by the way.
