My recollection is quite different. I remember his political opponents started to use it quite extensively during the Clinton campaign, but that was a mistake, because trust in journalism is lowest amongst Republicans. So Trump started using it in the sense of "what, that isn't fake news, YOUR news is fake news" and from there it took off. But it's a term used mostly by the left, as far as I can tell. At least they're much more obsessed with the idea.
