@Tweeter88455854 led me to this video. I've asked the OP for his Twitter account.
There's some chatter about this possibly being a "Lav Mic". I don't know anything about sound design, but I did research it. It doesn't make sense to use one if there are Mic's at the podium. So, the best way to settle this is to ask @realDonaldTrump if he also had a Lav Mic. ?
I've hit my limit to follow back, Patriots! I promise to follow back when able. IFBAP! (Thank YOU for the follows!)
