There's an extended video that shows a lift spewing hydraulic fluid with one more gunshot. I'm guessing homie moved and the secret service donated a bit more lead.
Edit. He was firing the left of the stage from our viewpoint, so he probably did hit the poor lift.

Put every marginalized person on one track and trump on the other. Do you pull the lever?
