I posted in the original annoucements thread for this that The Des Moines Register newspaper stated (paraphrase) that the event was closed to the media.

That said, it looks like someone found a snippet here, and maybe more will surface.

Unfortunately, it's my belief there won't be any official video drops, unless Trump himself puts them up via his official channels, which he may.

Again, this is all just IMO. I would love to be proven wrong!

Edit: wrote this before I had a chance to view the snipper u/tenthousandpoons linked. Not much changed, but I did see another snippet posted in these forums from a different angle and slightly earlier. So it appears recordings by attendees were no discouraged. Hopefully more surface. WWG1WGA.
