null - Thomas Matthew Crooks was the shooter in the apparent assassination attempt of former President Donald Trump at a campaign rally in Butler, Pennsylvania, the Federal Bureau of Investigation said early Sunday.
Trump, who was immediately pulled from the stage by Secret Service agents, said late Saturday that he'd been shot in the ear but expects to be fine. One person in the crowd was killed and two were badly wounded.
The gunman, meanwhile, was killed by the Secret Service.
The attack marked the most serious assassination attempt on a president or presidential candidate in the U.S. since Ronald Reagan was shot in 1981.

Not long after Trump was whisked from the stage with blood on his face, witnesses reported that they'd seen a man with a rifle "bear crawling" along a rooftop outside of the rally. That man was shot by agents after he opened fire, witnesses said.
The Secret Service would only confirm that they'd "neutralized" the gunman, who was firing from an elevated position. Later in the night, the FBI named Crooks as the shooter.

Crooks' father, Matthew Crooks, told CNN late Saturday that he was trying to figure out "what the hell is going on" but wouldn’t speak about his son until after he talked to law enforcement.
Investigators recovered an AR-style rifle at the scene, according to a person familiar with the matter who spoke on condition of anonymity to discuss the ongoing investigation. Investigators believe the weapon was bought by the father at least six months ago, two law enforcement officials told The Associated Press.

The AP also reports bomb-making materials were found inside the suspect's car, and there were also bomb-making materials found at his home.
Authorities didn't immediately give details on a motive and the political leanings of Crooks were not immediately clear.
"We do not currently have an identified motive," Kevin Rojek, Special Agent in Charge of the FBI Pittsburgh field office, told the AP.

Trump shooting: suspect identified after shooting at rally
The FBI identified the shooter as 20-year-old Thomas Matthew Crooks of Bethel Park, Pennsylvania. Crooks was a registered Republican, according to state voter records. The FBI told reporters the agency has taken the lead in investigating the attack.
Crooks was a registered Republican, according to voting records, but had only participated in the Nov. 8, 2022, state election due to his age. The day Joe Biden was inaugurated, records show, he made a $15 donation to Progressive Turnout Project, a Chicago-based political action committee that supports Democrat candidates for public office and claims to advocate for "key Democratic constituencies: young people, minorities and low-income people."
Crooks graduated from Bethel Park High School in 2022, FOX News reported. He was one of nearly two dozen students from the school to earn a $500 "star award" from the National Math and Science Initiative.

Trump shooting: Here’s what microphones picked up
Several shots were reportedly fired at former President Donald Trump during a Pennsylvania rally, causing screams from the crowd as Secret Service agents, noticing he was bleeding from the ear, quickly escorted him off the stage.
In a statement on social media, Trump said he was "shot with a bullet that pierced the upper part of my right ear." It took two minutes from the moment of the first shot for Trump to be placed in a waiting SUV.
Butler County District Attorney Richard Goldinger informed CNN that, besides the spectator who was killed, another attendee is in serious condition at a local hospital.
"The shooter is dead," Goldinger confirmed.
He mentioned that the shooter was outside the rally grounds but didn't provide further details about the location.
"Quite frankly, I don’t know how he would have gotten to the location where he was, but he was outside the grounds, and I think that’s something that we’re going to have to figure out — how he got there," Goldinger told CNN.
