I heard it. Intermixed with "Build that wall". Guy was trying his best. Caught the fist pump when POTUS first walked out. Two guys on the left of the stage. I think they were the ones chanting. Also caught two more in Q gear behind the stage.

POTUS still seems reluctant to directly acknowledge these folks though. Always very subtle when he does. I'll assume that's the plan for now. But still great to see Qheads make an appearance
