The fact that his guy made a B-line for Holt with the folder is very suspicious. If he was just a cleaner, he could have taken the notes and just exited the stage. Also, this looks like a senior guy, not a flunkie. Lastly, its a folder, not just a note pad.
The look from the guy to Holt at the end was “we did it!” moment. He didn’t even go look at Trump’s podium. Why is that?
