Not sure what the original is. This substack has a large share count on it.

The actions of the guards on stage, especially pushing over the Trump mic stand seem to match the other footage.

The physics of the woman pulling the photographers at the end matches too. The only thing that looks off is the security guard at 0:10 doing a weird hop

This older video from opposite angle also has the photographers coming in around 0:20 https://files.catbox.moe/1mlyvx.mp4
