Trump shot at rally in failed assassination attempt. Here's everything we know so far.

Former President Donald Trump was shot and injured in an assassination attempt on Saturday night that also killed a spectator and critically injured two others. Snipers killed the shooter, a 20-year-old man, after he fired eight rounds at the rally in Butler, Pennsylvania.

The former president could be seen touching his ear as the shooting unfolded before he was shielded by Secret Service and whisked offstage — with blood on his face — and into an SUV to safety. Trump said in a social media post that a bullet pierced the upper part of his right ear.

"I knew immediately that something was wrong in that I heard a whizzing sound, shots, and immediately felt the bullet ripping through the skin," he said. "Much bleeding took place, so I realized then what was happening."

The Secret Service later said Trump was safe, and that he went to a local hospital and left hours later. 

The gunman was fatally shot by a Secret Service sniper, authorities said. 

FBI officials said the shooter appeared to be a lone actor, and the incident was being investigated as an assassination attempt and as a potential case of domestic terrorism.

Who shot Donald Trump?

The FBI identified the shooter early Sunday as 20-year-old Thomas Matthew Crooks, of Bethel Park, Pennsylvania. The town in Allegheny County, just outside Pittsburgh, is home to about 30,000 people.

Law enforcement officials say he was armed with a semiautomatic AR-style rifle. Two law enforcement sources say the gun was legally purchased by and registered to the shooter's father, Matthew Crooks. 

Crooks was a 2022 graduate of Bethel Park High School  School officials pledged to work with law enforcement investigating the shooting, and offered condolences to those affected by the attack.

Former classmate Jameson Myers, a member of the school's varsity rifle team, told CBS News that Crooks had tried out for the team freshman year but did not make the junior varsity roster and did not return to try out for the team in subsequent years.  

He called Crooks a "nice kid who never talked poorly of anyone," adding, "I never have thought him capable of anything I've seen him do in the last few days."
