The White House says it is not behind a violent video shown at a pro-Trump event that showed a likeness of President Donald Trump mass murdering his political opponents and news outlets.

The video, taken and edited from the film "Kingsman: The Secret Service," depicts a violent scene involving Trump opponents like the late Sen. John McCain and Sen. Bernie Sanders, among others.

The video surfaced after it played at Trump's own resort over the weekend. The American Priority Festival that played the clip called it an "unauthorized video" that was "not approved, seen, or sanctioned" ahead of time.

Po Murray, head of the Newtown Action Alliance, says the video made her sick to her stomach.

"We work with families that have been severely impacted by these mass shooting tragedies, and to see it glorified in that type of fashion is just despicable," says Murray.

The Trump campaign says it is not behind the video and that it does not condone political violence.

As of Monday afternoon, the video was still available on many social media channels.

Back in Newtown, the explanations are good enough for J.T. Lewis, whose brother died at Sandy Hook. Lewis is now running for state Senate as a pro-Trump Republican. He says the president "shares no blame" for what an outside group created.

But Sen. Richard Blumenthal says social media platforms do share the blame -- the video has been on YouTube for more than a year.
