Photojournalists at the event managed to capture many of the scenes unfolding before them ― including the immediate response from the attendees and from the former president himself, who raised a fist in the air as law enforcement tried to protect him.
Here are some of the many photos that documented what authorities have described as an assassination attempt ― an event that will likely be remembered as a significant moment in U.S. history.
The Shooting
Trump was speaking at his rally in Butler when several shots rang out and threw the event into chaos. Images show Trump with a bloodied right ear and blood smeared on his right cheek as Secret Service agents and campaign staffers rush to protect the candidate and civilians.
Agents initially ducked and covered Trump before hurrying him off the stage. In the stands, images appear to show some spectators bloodied or hiding under benches.
