Pressure mounts on Secret Service as investigations continue

A new video clip shared on social media shows the confusion and disbelief among the crowd at Saturday’s rally in Butler, Pennsylvania.

A Trump supporter was seated to the right of the stage filming the former president’s speech as he spoke about immigration statistics.

Then the supporter, wearing a pair of stars and stripes sunglasses and a bandana, pans the camera toward himself. Before he can rotate his phone back toward Trump, three sharp snaps are heard.

The man and the people around him hit the floor as more shots are heard and people shout “get down, get down!” and “somebody got shot!”

The crowd applauds wildly as Trump gets back to his feet, led by Secret Service agents and chants of “USA” erupt.

Rallygoers then begin to clear the path for an injured person to be taken away for treatment.
