What happens when the president spots a Q supporter in the audience at a rally? Reddit link. President plainly draws a Q as he acknowledges a rally goer who obviously / apparently is wearing a Q shirt or has a Q sign. This was, I think, at the rally previous to the last one.  POTUS nods his head and grins. He is basically saying "Yes, I know," and gives the person a thumbs up. https://www.reddit.com/r/greatawakening/comments/8fo1o8/q_signature/
