WATCH: Video Shows Attempted-Trump Assassin on Roof Before Shooting

A new video appears to show Thomas Crooks moving across a roof in plain sight minutes before attempting to shoot Donald Trump.

In the video, taken by James Copenhaver, who was injured in the shooting, a figure is seen moving across the roof of the American Glass Research building moments before gunfire rang out in Butler, Pennsylvania.

The video was taken at 6.08pm on July 13, three minutes before Crooks, 20, opened fire, narrowly missing the former president.

One bullet grazed Trump’s ear, while Corey Comperatore, a local fire chief and Trump supporter, was killed and two other rally attendees were injured.

The shooting led to a bipartisan outcry over the security failures and last week Kimberly Cheatle resigned as director of the Secret Service after accepting responsibility for the “significant” problems surrounding the shooting.
