Body camera footage shared by U.S. Senator Chuck Grassley of Iowa sheds new details on the assassination attempt against former President Donald Trump—and raises additional questions.

On July 13, a 20-year-old gunman fired several shots from an AR-15-style weapon during Trump's campaign rally in Butler, Pennsylvania. The U.S. Secret Service has faced pressure from both sides of the aisle over how the young assailant was able to get a clear shot on Trump, who was grazed on the tip of his right ear in the shooting. The gunman, Thomas Matthew Crooks, fired his weapon from the roof of a building less than 200 yards from the podium where Trump was speaking to supporters.

Grassley posted a roughly three-minute video to his X, formerly Twitter, account Tuesday evening of body camera footage that showed law enforcement on the rooftop where Crooks was positioned. The video shows a group of counter-snipers talking with a Secret Service agent while Crooks can be seen lying on the roof near a stream of blood.
