Two eyewitnesses who captured cellphone video of a gunman firing at former President Donald Trump during a campaign rally in Butler, Pennsylvania, recounted the harrowing experience of trying to warn authorities of the shooter's position amidst the chaos.
The witnesses described how they first noticed something was amiss when they saw people running in the crowd and spotted a man on the roof of a nearby building. Upon realizing the man had a gun, they quickly tried to alert law enforcement.
