Utah Gov. Spencer Cox warned Friday that social media is "a cancer on our society right now" and called this a "watershed moment" in the nation's history. The Utah governor was referencing the rapid spread of graphic video of Kirk’s fatal shooting, along with the recent release of video a deadly stabbing on a commuter train in Charlotte, North Carolina. Cox told reporters the gruesome shooting of Kirk is reminiscent of the political assassinations of the late 1960's. He said Americans aren’t used to seeing such graphic imagery. He encouraged people to step away from their devices and spend time with family instead. “This is not good for us. It is not good to consume,” Cox said. “Social media is a cancer on our society right now.” Cox also urged Americans to come together to discuss their political differences. "Do we escalate or do we find an off-ramp? And again, it's a choice. It's a choice. And every one of us gets to make that choice," he said. "Is this the end of a dark chapter in our history or the beginning of a darker chapter in our history?" Cox asked. The Utah governor was speaking at a news conference to announce the arrest of a suspect in the shooting Wednesday of conservative activist Charlie Kirk.
