A timeline of the assassination attempt on former U.S. president Trump

'He kept to himself': Former classmate of shooter The FBI has identified the shooter as 20-year-old Thomas Matthew Crooks who former classmates describe as 'lonely and quiet'.

Former U.S. president Donald Trump was the target of an assassination attempt at a Pennsylvania rally Saturday that set off panic as a bloodied Trump was surrounded by Secret Service and hurried into his vehicle.

A former fire chief attending the rally with family was killed, as was the gunman. Two other people were critically wounded.

An AP analysis of more than a dozen videos and photos from the scene of the Trump rally in Butler, Pennsylvania, as well as satellite imagery of the site, shows the shooter was able to get astonishingly close to the stage where the former president was speaking.

Here's what's known so far about the timeline of the shooting.

6:02 p.m. ET

Trump takes the stage to the strains of "God Bless the U.S.A." He waves at the cheering crowd and begins his regular rally speech, with spectators both in front of him and behind him on risers.

Around 6:10 p.m.

About 1 minute after the shots

Trump turns back to the crowd and again raises a fist right before agents put him into a vehicle and he is taken to a local hospital.

6:50 p.m.

Secret Service says "the former President is safe."

8:42 p.m.

Trump posts on his social media site that he was injured in 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.

About 12:10 a.m.

Trump's private jet lands at Newark Liberty International Airport.

Video posted by an aide showed the former president deplaning, flanked by U.S. Secret Service agents and heavily armed members of the agency's counter assault team. It was an unusually visible show of force by his protective detail.

Trump travels to his private golf club in nearby Bedminster, New Jersey, to spend the night.
