Trump assassination attempt timeline: Witnesses spotted gunman 2 minutes before shooting

The world is reeling from the assassination attempt against former President Donald Trump during his campaign rally in Pennsylvania on Saturday, which left one spectator and the suspected gunman dead, according to officials.

Shots rang out just moments after Trump stepped onto the outdoor stage at the event, with one of the bullets striking Trump's right ear.

Secret Service agents swarmed Trump as he ducked behind the podium, with blood dripping down the side of his face.

Below is a timeline of events from the harrowing and deadly scene at the rally:

Saturday, July 13, 6:05 p.m. Trump walks onto the stage in Butler, Pennsylvania

Trump took the event stage at Butler Farms in Pennsylvania just after 6:00 p.m. local time as supporters cheered for the former president.

Officials said that all rally attendees went through a Secret Service screening checkpoint before being admitted to the event.

A team of Secret Service snipers were positioned on a rooftop behind Trump as the rally began.

Trump walked to the podium and began speaking to the audience.

6:09 p.m. Witnesses notice the gunman

Two minutes before shots rang out, witnesses noticed a gunman on the roof of a nearby building outside of the security perimeter.

The gunman was positioned approximately 400 feet away from the former president.

Onlookers then called for police, verified video shared online shows.

6:10 p.m. Law enforcement seen looking for suspect

During the minute before the shooting began, law enforcement officers appeared to be searching for the suspected gunman.

A bystander captured what appears to be local law enforcement walking around the structure the suspected shooter was positioned on.

Local law enforcement later told ABC News they had been alerted to suspicious activity in the area and were in the process of looking for a potential suspect.

6:11 p.m. Gunfire erupts

Trump was eight minutes into his speech when the shooting began, according to officials.

The former president was describing a chart showing statistics on immigration and turned his head to look at it while saying, "Take a look at that chart. Take a look at the arrow on the bottom."

Trump continued, calling out President Biden's immigration policy, saying, "And then the worst president in the history of our country took over and look what happened to our country."

Trump was cut off when he said, "Probably 20 million people," by the loud popping sounds of shots being fired and a rally attendee yelling, "He’s got a gun!"

"He's on the roof! He's got a gun!" the attendee can be heard saying in video footage from the event.

6:11 p.m. continued

As shots rang out and the event erupted into panic, Trump was seen clutching his right ear and ducking behind the podium.

Three Secret Service agents swarmed to cover Trump, yelling, "Get down!" as multiple additional rounds of gunshots were fired. Blood was seen smeared across the former president's face and onto his hand in images captured at the event.

The shooter fired as many as eight rounds from an AR-style rifle while perched on a rooftop adjacent to the venue and was 200-300 yards away at the time of the shooting, law enforcement sources told ABC News.

6:12 p.m. 1 spectator killed, 2 others critically injured; gunman also killed

Another round of shots was fired as snipers in Trump's Secret Service detail killed the suspected shooter.

One spectator who was sitting behind the former president during the rally was killed, and two others were critically injured, according to officials.

6:12 p.m. continued

Secret Service agents swiftly escorted Trump off the rally stage and into a waiting vehicle.

There appeared to be blood on Trump's right ear as he was being taken off stage, and he could be seen mouthing "fight" and pumping his fist.

Many rally attendees were seen trying to find cover while others remained in their seats chanting "USA!" as Trump was escorted off the stage.

"I’m grateful to hear that he’s safe and doing well. I’m praying for him and his family and for all those who were at the rally as we await further information," the president added.

Later in the evening, during a televised news conference, Biden reiterated his early statement and added, "The idea that there's political violence or violence in America like this is just unheard of. It’s just not appropriate."

Biden said he was trying to get ahold of Trump on the phone and wanted to talk to him.

"There is no place in America for this violence. It's sick," he said.

On Saturday evening, Trump released a statement on his Truth Social platform, confirming he was shot "with a bullet that pierced the upper part of my 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. Much bleeding took place, so I realized then what was happening," he said.

Trump thanked the Secret Service and law enforcement for the rapid response and extended his condolences to the family of the person who was killed and the injured.

"It is incredible that such an act can take place in our Country," he said in his statement.
