I not sure this has been mentioned yet.
But the flag is backwards of how it should be displayed, unless it's hanging in a window and Trump is inside.
"When displayed either horizontally or vertically against a wall, the union should be uppermost and to the flag's own right, that is, to the observer's left. When displayed in a window, the American flag should be displayed in the same way, with the union or blue field to the left of the observer in the street."
== Sure enough, Trump is standing inside a building with the flag behind him, along with a window behind the flag."
Powerful light shining through the window. I'm assuming the photo is from the WH.
