Consider adding a section on worldwide trend/how the idea of "alternative facts" - while not specifically called that - is more that just an American phenomenon.
Possible source - https://www.washingtonpost.com/opinions/the-alternative-facts-epidemic-goes-way-beyond-politics/2017/04/05/01a75ee0-1966-11e7-855e-4824bbb5d748_story.html
Also, consider a section on the non-political effects of "alternative facts".
Add a paragraph in the Background section about the connection to Stephen Colbert's "Truthiness" and how, despite the fact that the term "alternative facts" has recently surfaced, it is not a recent phenomenon.
Also, consider changing the photo.
My edits have been on our group google doc. See Eric's sandbox for the paragraph we have been working on.
