Rep. Mike Kelly (R-PA) called for unity and responsibility Sunday in the wake of Saturday's attempted assassination of former President Donald Trump.

“Physically, I’m fine. Mentally, I’m fine. But … This has got to stop. This has absolutely got to stop,” the lawmaker said during a Sunday interview with The Hill.

Kelly represents the district in which the assassination attempt occurred and attended the rally at which the former president was speaking.

“It’s a time to … take a deep dive into what happened to America. This is certainly not the America that I grew up in, and that my parents had gone through the Great Depression, World War II to make sure we had a future. But that’s what we are right now, as we are right now, like a third-world country,” Kelly said. “It’s not the United States of America anymore. It’s the divided states of America – and too radical.”

The lawmaker described the incident as “surreal” and described seeing rallygoers panicking during and after the exchange of gunfire. He highlighted the role incendiary rhetoric could have played in motivating the gunman to make the assassination attempt. He argued that “you have to be responsible for what it is you say” and that Americans “need to start taking personal responsibility for that.”

“It’s not any one party, it’s not any one group of people,” he added.

The shooting wounded Trump in his ear and killed one of the rallygoers. Twenty-year-old Thomas Matthew Crooks, the man believed to have carried out the shooting, was killed by Secret Service gunfire.

A former volunteer fire Chief for Buffalo Township, Corey Comperatore, age 50, lost his life after being struck with a bullet shot by 20-year-old Thomas Matthew Crooks. According to his sister, Dawn Comperatore Shafer, Corey was hit as he shielded his daughters from the gunfire that ensued just minutes into Trump's speech.

On Facebook, Comperatore Schafer wrote:

The PA Trump Rally claimed the life of my brother, Corey Comperatore. The hatred for one man took the life of the one man we loved the most. He was a hero that shielded his daughters. His wife and girls just lived through the unthinkable and unimaginable. My baby brother just turned 50 and had so much life left to experience. Hatred has no limits and love has no bounds. Pray for my sister-in-law, nieces, my mother, sister, me and his nieces and nephews as this feels like a terrible nightmare but we know it is our painful reality.

Kelly insisted that the nation needs to unite and move past the ongoing division that permeates national political discourse.

“It’s time for the whole country – the whole country – to wake up,” Kelly asserted. “This has gotten to the point that that’s just no longer tolerable.”

Kelly also called on people to consider the rhetoric they use to try to calm the situation down.

“If you want to know how to fix the country, please find a mirror and go take a look at it and say, ‘So am I also responsible for this in one way or another? Maybe some of the things that I’ve texted out, there are some things I’ve said to people?’ ” the lawmaker said.

The authorities are still investigating the shooting. Explosives were reportedly found in Crooks’ vehicle, which was parked close to the event. While they have identified the shooter, they have not yet ascertained his motive, nor has his political affiliation been established.
