The fallout continues from the assassination attempt against former President Donald Trump during his campaign rally in Pennsylvania on July 13, which left one spectator and the suspected gunman dead, according to officials.

Shots rang out soon 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:

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 Joe 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.

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 to 300 yards away at the time of the shooting, law enforcement sources told ABC News.

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.

"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."

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.
