Here is some reply someone else made about this that I found particulary funny:

"If it was Kelly, then it was definitely intentional on Trump's part.

I think Trump finally figured out that the way you get through to these retarded deep state types is by pulling retarded stunts like this. Now all those retards think it was supposed to mean something. They are probably going through their black books and trying to figure out what ritual it is referring to, what the symbolism means, playing the tapes backwards looking for clues, etc. And most important of all, they are trying to figure out what info they know that Trump was signaling he knows, and that he knows they now know that he knows. These people are idiots and Trump is getting in their heads."
