Nope, not coined by Trump. I did a bit of research. I found "fake news" in this link from 2005 on democracynow.org: https://www.democracynow.org/2005/3/14/state_propaganda_how_...

I'm not trying to say that people who use the term now are using it in place of "pizzagate", but that media outlets, during the months of December 2016 and early 2017, used the phrase to talk around "pizzagate"; and now "pizzagate" has faded, but "fake news" remains.

I think propaganda is a more appopriate word, and we should just use that. But because of the way associations work, whenever I see "fake news", I am reminded of "pizzagate". And I know I'm not the only one.
