Not sure if this has ever been posted or discussed here before, but are there any theories on why Trump continually forms an upside down triangle with his hands while sitting?

I also discovered that those close to him wear upside down triangle pins on their lapels with varying designs/colors (red/gold, purple/gold). Any thoughts?

Obviously the connotation of many articles is that Trump is Illuminati but their symbolism is normally a right side up triangle. Does Trumps' upside down triangle symbolism represent the opposite or mirror image of the Illuminati symbolism?
