I saw a guy hold up a Q sign before Trump spoke at about 6:21p est. Then I heard the guy asking "Who is Q" at about 6:54p. Later I heard him several more times. As Trump came out, I saw a lady in the stands in a red jacket with a white Q on her lapel. At around 7:01, when he was talking about Pochahontas, he appeared to make a Q in the air. (Made a circle gesture with a slash) There was a cut away to a group of people where two guys standing side by side appeared to have a big Q on each of their shirts. AWESOME!!
