Surveillance footage reviewed by The Washington Post shows that Cole Tomas Allen appeared to raise his shotgun in the direction of a Secret Service officer who then fired the only shots that are clearly visible in the video from a security checkpoint outside Saturday’s White House correspondents’ dinner.

The video, a much higher resolution version of the security camera footage President Donald Trump posted to social media that night, does not capture every gunshot that authorities say was fired. But it provides the clearest picture yet of the four seconds between when Allen burst out of a doorway in full sprint and when he exited the frame, falling to the ground at the top of a staircase leading to the ballroom at the Washington Hilton where Trump sat near Vice President JD Vance and multiple members of his Cabinet.
