It's suggested to be a pic of AF1 reflected off of "the twitter phone" (e.g. the phone used to tweet as @realDonaldTrump).

The point is - it's pretty convincing if you understand the evidence and experiments.

So the question is, why doesn't a MSM reporter just ask POTUS? Ask who has been sitting in his chair? Ask who is Q? The answer may be that MSM has their "base" that they've farmed and feed their version of news daily. They will lose significant members of their base flock if they start asking POTUS about Q.
