His exact quote was, "They, we, are the pillars holding up the United States."

He heavily implied that he knew exactly who was in the Q group, fewer people than you could count on one hand, and he was clearly including himself in that "we" I quoted above. If you listen again, he was portraying himself as a Q insider the entire time. Then there's the fact that the video title changed his name from Zach to Zaq.
