I found this trending post on Reddit.

Sure, it's weird seeing the president (at the time) being served by the founder of Wagner Group.

But no one on Reddit seems to be making a big deal of the subliminal 'mushroom cloud' in the corner.

To me, it would have been put there intentionally to work subliminally on the President and his wife.

Why he gets staff to dress up like this though is anybody's guess...
