- The video features clips of violence and a bloodied police officer
- It was originally posted last week by an account named "trumpeffect"
The video, which a Trump supporter originally posted on Twitter, splices a clip of a gun firing into the air with footage from a canceled Trump rally in Chicago during which fistfights broke out between Trump supporters and protesters.
There has never been a report of a gun being fired in connection with a Trump rally or protests.
"We're at war. No one wants to admit it but humanity is under attack," the narrator, whose voice can be recognized as that of actor Martin Sheen, says over rolling clips of protests. "One very specific man might be all that stands between humanity and the greatest threat of our brief existence."
The narration is pulled from Sheen's voice-overs for the video game Mass Effect 2.
The video was originally posted last week on the website Vidme by an account named "trumpeffect."
Trump's social media director Dan Scavino also shared the video on Twitter late last night.
The video includes chaotic scenes and a clip of Democratic presidential front-runner Hillary Clinton laughing, President Barack Obama lifting weights and images of the moon landing.
