The U.S. Secret Service and FBI on Thursday responded to a video recorded by James Copenhaver, one of the victims wounded in a July 13 assassination attempt against former President Trump, showing a figure moving across the roof of the building gunman Thomas Crooks shot from.

The video that Copenhaver shared exclusively with Fox News Digital was taken at 6:08 p.m. on July 13, minutes before Crooks fired at least eight gunshots at 6:11 before counter snipers killed him.

“The Secret Service is committed to better understanding what happened before, during, and after the assassination attempt of former President Trump to ensure that never happens again,” the agency told Fox News in a statement. “That includes complete cooperation with Congress, the FBI and other relevant investigations.”

The FBI told Fox News it is aware of the video but has no further comment.
