Secret Service Director Kimberly Cheatle testifies on Trump assassination attempt

The US Secret Service director has been grilled repeatedly during today’s House hearing about how the shooting during Donald Trump’s rally unfolded — and what her agents were doing before and after.

Through videos, maps and photos, CNN pieced together what occurred from the start of the rally to the chaotic moments when gunshots erupted to, ultimately, when Trump landed in Newark, New Jersey, early Sunday morning.

Here’s how the shooting unfolded:

6:05:12 p.m. ET: Trump starts addressing his supporters and speaks for roughly six minutes before the scene erupts into chaos.

6:09 p.m. ET: Video shows some attendees notice the gunman on the roof at least one minute and 57 seconds before the shooting begins, based on an analysis comparing this video to the moments in Trump’s speech. At least one law enforcement officer appears in the video to be walking around the building where the gunman is on the roof. You can see the gunman laying down on the roof crawling as people in the crowd shout out that there’s someone on the roof. Several rally attendees try to call attention to the gunman as Trump is speaking on the stage.

Trump is in the middle of speaking when someone in the crowd is heard saying, “He’s got a gun.” As the video captures someone in the crowd repeating, “On the roof. He’s got a gun,” three shots ring out. A pause and five more shots in rapid succession are heard, along with a final shot of a different tone. “Stay under here,” an attendee says in the video. 

6:11:33 p.m. ET: Trump pauses mid-sentence as shots ring out.

6:11:34 p.m. ET: Trump touches the right side of his face.

6:11:35 p.m. ET: Trump takes cover as US Secret Service agents rush to the podium to surround him. “Get down, get down, get down,” one says.

While the gunman is positioned outside the rally venue, the distance between him and where Trump is speaking is only approximately 400 to 500 feet. CNN has learned that the gunman accessed the roof by climbing a building AC unit, though the timing of this action is not known.
