Corey Comperatore has been identified as the crowd member who died on Saturday night in the assassination attempt on Donald Trump. 

Comperatore, 50, a retired fire chief for Buffalo Township, was killed by 20-year-old registered Republican and Biden donor, Thomas Matthew Crooks, at Trump's rally in Butler, Pennsylvania. 

A bullet hit Trump's ear, while the father-of-two, sitting behind the former president, was killed. He died a hero as his family revealed he was shielding his young daughter and wife from the gunfire when he was struck himself.

'Corey dove on his family to protect him last night, he died a hero, he was the very best of us,' Pennsylvania Governor Josh Shapiro said in a press conference on Sunday afternoon.

He's been remembered as a 'girl dad', a loving husband, a man who went to church every Sunday, and an 'avid supporter of Trump.' Comperatore was 'so excited' to be at the rally on Saturday night. 

Members of the audience tried to save the father's life in the bleachers in Butler after Crooks opened fire from a rooftop 130 yards away.

Family members paid tribute to Comperatore who was well-known in the community.

His sister, Dawn Comperatore Schafer, wrote on Facebook: '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.' 

His heartbroken daughter Allyson, who was protected by her father from the bullets, also paid tribute to her late father. 

'Yesterday time stopped. And when it started again my family and I started living a real-life nightmare.

'He was the best dad a girl could ever ask for. My sister and I never needed anything. You call, he would answer, and he would do whatever it is you needed, and if he didn't know how he would figure out how,' Allyson said. 

'They are not going to tell you how quickly he threw my mom and I to the ground. They are not going to tell you that he shielded my body from the bullet that came at us. 

'He loved his family. He truly loved us enough to take a bullet for us,' she continued in the emotional tribute. 

On Saturday evening while the 45th president was speaking on stage in Butler, a barrage of rifle rounds quickly rained down. 

Trump grabbed the side of his head and ducked as bullets whizzed by and screams from terrified onlookers rang out.

An emergency room doctor at the rally revealed how he performed CPR on Comperatore, after he was hit by a bullet intended for the former president. 

Secret Service agents could be heard shouting 'the shooter is down' in the ensuing chaos and the gunman was later confirmed dead.

Trump soon got to his feet with blood pouring down his cheek and raised his fist in the air and defiantly shouted 'fight' while the audience shouted 'USA' as he was dragged off stage and bundled into a vehicle.

He was taken to the hospital for treatment before being later released. Two other supporters were left in critical condition after the shooting.
