Former president Donald Trump has confirmed he was shot in the upper ear while he was speaking on stage at a campaign rally in Pennsylvania.

Multiple shots were fired toward the stage by a shooter at Trump's rally in Pennsylvania about 6.10pm on Saturday (local time), leaving one spectator dead and two critically injured, according to the Secret Service.

The shooter was then killed by the Secret Service.

Who shot at Donald Trump?

The FBI has this afternoon named Thomas Matthew Crooks, 20, of Bethel Park, Pennsylvania, as the subject involved in the assassination attempt.

The political leanings of Crooks were not immediately clear.

Records show he was registered as a Republican voter in Pennsylvania, but federal campaign finance reports also show he gave US$15 ($22) to a progressive political action committee on January 20, 2021, the day President Joe Biden was sworn in to office.

Speaking at a press conference earlier this afternoon, FBI Deputy Commissioner of Operations Lieutenant Colonel George Bivens said authorities were yet to identify the initial shooter and the motive behind the attack, but would not rule out whether the gunman acted alone.

"I think it's too early to say that we have one shooter tentatively identified, but we're not stopping there," he told reporters.

"We are absolutely not taking for granted that this was a lone wolf attack and so we would be looking at additional information that could point us to anyone else that may have had a hand in this.

"We're following up on a lot of information. It will be some time until we can conclusively say or answer that question."

Bivens said their greatest priority was identifying the motive and whether other parties were involved in the attack.

"I think once the shooter is identified anyone that has specific information on that shooter, that would be very helpful also," he said.

The agency said the investigation remains active and ongoing.

Was the shooter attending Donald Trump's rally?

Butler County District Attorney Richard Goldinger said the shooter was outside the rally grounds at the time of the attack, but he didn't give additional information about where.

"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," he said.

Multiple shots were fired toward the stage by the shooter the Secret Service said, leaving one spectator dead and two critically injured.

The agency said the shooter fired from "an elevated position outside the rally venue." Agents "neutralized" the shooter, who is now dead.

WHAT WE KNOW: Everything we know about the Trump rally shooting

The agency said the shooter fired from "an elevated position outside the rally venue."

Witness Greg Smith told the BBC he saw a man crawling on top of a building just outside the event in Butler County around five minutes into Trump's speech and alerted police.

"We noticed the guy bear-crawling up the roof of the building beside us, 50ft away," he said.

"He had a rifle, we could clearly see a rifle."

Smith said he later saw the agents shoot the gunman: "They crawled up on the roof, they had their guns pointed at him, made sure he was dead. He was dead, and that was it – it was over."

What kind of weapon did the shooter have?

Law enforcement recovered AR-style rifle at scene of Trump rally shooting, AP source says.

Trump's message on his Truth Social account explains he was shot by a bullet that pierced the upper part of his right ear.

"I 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. GOD BLESS AMERICA!" he wrote.

The US Secret Service is investigating how a gunman armed with an AR-style rifle was able to get close enough to shoot and injure former president Donald Trump at a rally in Pennsylvania, a monumental failure of one the agency's core duties.

The gunman, who was killed by Secret Service personnel on Saturday (Sunday morning AEST), fired multiple shots at the stage from an "elevated position outside of the rally venue," the agency said.

An Associated Press analysis of more than a dozen videos and photos taken at the Trump rally, 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.

READ MORE: Trump gunman named as FBI probes motive

A video posted to social media and geolocated by the AP shows the body of a man wearing grey camouflage lying motionless on the roof of a manufacturing plant just north of the Butler Farm Show grounds, where Trump's rally was held.

The roof was less than 150 metres from where Trump was speaking, a distance from which a decent marksman could reasonably hit a human-sized target.

For reference, 150 meters is a distance at which US Army recruits must hit a scaled human-sized silhouette to qualify with the M16 assault rifle in basic training. The AR-15, like the shooter at the Trump rally had, is the semi-automatic civilian version of the military M16.

A witness told the BBC that roughly five to seven minutes after Trump started speaking his group noticed a man bear crawling on the building near them.

"We could clearly see him with a rifle. Absolutely. We're pointing at him," the witness said.

"The police are down there running around on the ground. We're like, 'Hey, man, there's a guy on the roof with a rifle, and the police were like, 'Huh, what?' You know, like, like, they didn't know what was going on.

"You know, we're like, 'hey, right here on the roof', we can see him from right here."

The FBI early on Sunday (Sunday night AEST) identified the shooter as Thomas Matthew Crooks, 20, of Bethel Park, Pennsylvania.

The Secret Service didn't have anybody at a late-night news conference where FBI and Pennsylvania State Police officials briefed reporters on the shooting investigation.

FBI Special Agent in Charge Kevin Rojek said it was "surprising" that the gunman was able to fire at the stage before he was killed.

Members of the Secret Service's counter sniper team and counter assault team were at the rally, according to two law enforcement officials. The officials spoke on condition of anonymity because they weren't authorised to discuss details of the investigation.

The heavily armed counter assault team, whose Secret Service code name is "Hawkeye", is responsible for eliminating threats so that other agents can shield and take away the person they are protecting.

The counter sniper team, known by the code name "Hercules", uses long-range binoculars and is equipped with sniper rifles to deal with long-range threats.

US Secretary of Homeland Security Alejandro Mayorkas said his department and the Secret Service were working with law enforcement to investigate the shooting.

Maintaining the security of presidential candidates and their campaign events is one of the department's "most vital priorities", he said.

"We condemn this violence in the strongest possible terms and commend the Secret Service for their swift action today," Mayorkas said.

"We are engaged with President Biden, former president Trump and their campaigns, and are taking every possible measure to ensure their safety and security."

Calls for an investigation came from all sides.

James Comer, a Kentucky Republican who is the House Oversight Committee chairman, said he contacted the Secret Service for a briefing and called on Director Kimberly Cheatle to appear for a hearing. Comer said his committee will send a formal invitation soon.

"Political violence in all forms is unamerican and unacceptable. There are many questions and Americans demand answers," Comer said in a statement.

US Representative Ritchie Torres, a New York Democrat, called for "security failures" at the rally to be investigated.

"The federal government must constantly learn from security failures in order to avoid repeating them, especially when those failures have implications for the nation," Torres said.

Wisconsin Governor Tony Evers, a Democrat, posted on X that he and his staff were in contact with security planning coordinators ahead of the Republican National Convention set to begin Monday in Milwaukee.

"We cannot be a country that accepts political violence of any kind — that is not who we are as Americans," Evers said.

The FBI said it will lead the investigation into the shooting, working with the Secret Service and local and state law enforcement.

Attorney General Merrick Garland said the Justice Department "will bring every available resource to bear to this investigation".

"My heart is with the former president, those injured, and the family of the spectator killed in this horrific attack," Garland said in a statement.

"We will not tolerate violence of any kind, and violence like this is an attack on our democracy."

A Melbourne mum is demanding change after her son died following his first shift on a CFMEU government worksite.

Tammie Palmer claims 18-year-old Ben, who had mental health issues, was bullied to death.

In January, the Ringwood North man went to work his first day on a CFMEU site.

READ MORE: 'Too early' to determine if Trump shooter acted alone, says FBI

That night, before his 19th birthday, he died of an overdose.

"They locked him in a shed for three or four hours – just a young boy, with mental health issues," Palmer said.

While the CFMEU denies the claims, Palmer claimed her son, a proud Gunditjmara teen, was relentlessly bullied because he was wearing the shirt of a small Indigenous construction firm he'd previously worked for.

She said the CFMEU didn't like the firm because it was aligned with a rival union, the AWU.

"If Ben had another shirt on, none of this would be an issue," Palmer suggested.

9News obtained videos showing Ben's former boss from the same Indigenous firm receiving similar treatment from a CFMEU official, at another site."You're a f—ing rat. I declared you a dog in front of the boys, what are you going to do about it?" somebody can be heard saying.

"He would have felt worthless, useless, like he'd done something wrong," Palmer said.

Toxic workplace culture starts at the top

It's the kind of toxic worksite culture that starts at the very top, according to a months-long investigation from 9News, 60 Minutes and Nine newspapers.

Security vision shows ex-CFMEU boss John Setka dumping a suitcase with the words "Leo the dog" written on it outside the home of fellow senior union official Leo Skourdoumbis.

"I think the message is quite clear and that was – you speak out against us, we know where you are – and we can get to you," Skourdoumbis told 60 Minutes.

Setka said the claims were "more false allegations", adding "once again youse have put sauce on everything".

Palmer wants change, that's why she's speaking out, despite safety concerns.

"They can't hurt me more than I'm already hurting," Palmer said.

"People should be able to go to work and be treated with kindness and respect, it's not hard.

"All he wanted to do was work."

Already at the footy club, mental health has become a major priority.

"We're starting to find that a lot of the families are starting to engage directly with us, because the football club is a place of sanctuary for them," Chris Leahy from North Ringwood Junior Football Club said.

On Friday it was announced John Setka would step down as the CFMEU's Victorian secretary, effective immediately, the union said.

Setka received an icy farewell from Prime Minister Anthony Albanese following revelations that alleged organised crime figures had infiltrated the group.

ANALYSIS: There are events that define history, and the attempted assassination of former US president and presumptive Republican presidential nominee Donald Trump is one of those moments.

This will shape the remainder of the presidential campaign and if he didn't already have it in the bag, will help secure Trump victory over President Joe Biden.

The contrast between the two couldn't be clearer.

READ MORE: 'Praying for him': Joe Biden speaks after Donald Trump shooting

On the one side is the image of Trump, blood smeared across his face with his fist raised high as the American flag flies in the background, having survived a gunman's attack – defiance personified.

Even after dodging a bullet he stands at the lectern to chant "fight, fight", before being bundled by heavily armed Secret Service away to safety – one last fist bump before being driven from the frightening scene.

On the other side is a frail and infirm Biden, forgetting names and stumbling at every public appearance, who even senior members of his own party want to stand down from the race.

He is behind in the opinion polls and is now all but certain to lose the election on the first Tuesday in November.

It is remarkable that Trump has survived this gunman's attack and the Trump campaign will milk this appalling act of violence for all its worth.

What is surprising is that Americans are shocked that this attack occurred in the first place.

The personal attacks from both sides have been ramping up in a country that is deeply divided and armed to the teeth.

It's not just presidents and nominees who are the target of death threats and attacks, but also judges, campaign organisers and even independent electoral staff who are simply doing their jobs.

They and their families are subject to verbal threats and worse.

Sadly, this attack won't turn down the temperature in an increasingly volatile campaign, or provide pause for US lawmakers to reconsider their ludicrous gun laws.

This attack will only serve to provide greater impetus for Donald Trump to regain the keys to the White House.

The FBI has said it is "too early" to determine if the gunman who shot Donald Trump in the ear, killed an audience member, and critically injured two others at a campaign rally in Pennsylvania acted alone.

The former US president was shot in the ear mid-speech at an event in Butler about 6.10pm on Saturday (8.10am on Sunday AEST).

He was whisked off stage bloodied and shuffled into a security car by Secret Service agents in what law enforcement is treating as an attempted assassination.

The Secret Service said the shooter fired from "an elevated position outside the rally venue".

As multiple shots were fired from the stage one bullet fatally struck an attendee in the head, and two other attendees were critically wounded.

Agents "neutralised" the shooter.

The FBI this afternoon named Thomas Matthew Crooks, 20, of Bethel Park, Pennsylvania, as the subject involved in the assassination attempt.

The agency said the investigation remains active and ongoing.

The agency repeated that Trump is "safe" and is being evaluated.

An AR-style rifle was recovered from the scene, according to an official.

Trump later took his platform Truth Social to confirm a bullet had 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." the former president wrote.

"Much bleeding took place, so I realised then what was happening."

Vision shows the former president cowering to the ground before getting to his feet.

Screams were heard in the crowd of several thousand people and bangs continued as Secret Service agents tended to him on stage.

Trump appeared bloody with his right fist raised in the air before he was shuffled into a security car.

The shooting is being investigated as an attempted assassination of the former president and presumptive Republican nominee, law enforcement officials say.

No motive yet

Speaking at a press conference hours after the incident, special agent in charge of the FBI Pittsburgh field office Kevin Rojek appealed for public information about the deadly shooting.

"The FBI has deployed a number of our resources, including investigative agents, our evidence response team, bomb technicians, and we have additional resources coming from other field offices," he said.

WATCH: Video captures what happened at Trump rally

"We have intelligence analysts as well, working from our field office in Pittsburgh, working feverishly to attempt to identify the individual who did this.

"Anyone who was on scene who saw anything, who identified any information, please report that to the FBI."

Deputy Commissioner of Operations, Lieutenant Colonel George Bivens, would not rule confirm whether the gunman, who killed one audience member and critically injured two others, acted alone.

"I think it's too early to say that. We have one shooter tentatively identified, but we're not stopping there," he told reporters.

"We are absolutely not taking for granted that this was a lone wolf attack and so we would be looking at additional information that could point us to anyone else that may have had a hand in this.

"We're following up on a lot of information."

At this stage, Bivens said authorities are yet to identify the initial shooter and the motive behind the attack.

Bivens said several "suspicious packages" hindered attempts by law enforcement to take down the active shooter when a reporter asked why the suspect wasn't apprehended sooner.

"I am aware that law enforcement had responded to a number of reports of suspicious activity," he said.

"Their specific response will be part of the investigation after action. But law enforcement was responding to check on several suspicious occurrences."

Authorities said they were not prepared to release the identities of the civilians killed or injured, other than the former president.

Authorities did confirm all three victims were adult and male.

FBI surprised by rapid rounds

Asked if law enforcement did not know the shooter was on the roof until he began firing, Rojek responded: "that is our assessment at this time."

"It is surprising" that the shooter was able to get off as many rounds as were fired, Rojek said.

He added that "all the details of that will come out later investigation."

The Secret Service is investigating how the gunman was able to get close enough to shoot Trump, a monumental failure of one the agency's core duties.

A witness told the BBC that roughly five to seven minutes after Trump started speaking his group noticed a man bear crawling on the building near them.

"We could clearly see him with a rifle. Absolutely. We're pointing at him," the witness said.

"The police are down there running around on the ground. We're like, 'Hey, man, there's a guy on the roof with a rifle, and the police were like, 'Huh, what?' You know, like, they didn't know what was going on. 

"You know, we're like, 'hey, right here on the roof', we can see him from right here."

Event to go ahead

Despite the deadly shooting, the Republican National Committee Milwaukee will go ahead as planned on Monday.

RNC says Trump is looking forward to joining the committee.

"President Trump looks forward to joining you all in Milwaukee as we proceed with our convention to nominate him to serve as the 47th President of the United States," said Trump campaign advisers Susie Wiles and Chris LaCivita and Republican National Committee Chair Michael Whatley and co-chair Lara Trump in a statement.

A spokesman for Trump, Steven Cheung, had earlier released a statement saying Trump was "fine". 

"President Trump thanks law enforcement and first responders for their quick action during this heinous act," the statement reads.

"He is fine and is being checked out at a local medical facility. More details will follow."

As Trump was talking, a popping sound was heard. About six or seven shots rang out.

Trump said, "Oh," and put his right hand up to his right ear as people in the stands behind him appeared to be shocked. Two more pops could be quickly heard and he crouched down.

Someone could be heard saying near the microphone at Trump's lectern, "Get down, get down, get down, get down!" as agents tackled the former president.

They piled atop him to shield him with their bodies, as is their training protocol, as other agents took up positions on stage to search for the threat.

Police began vacating the fairgrounds shortly after Trump left the stage in what local officers described as a crime scene.

President Joe Biden addressed the incident in a press conference, describing it as "sick".

"There's no place in America for this kind of violence," he said.

"It's one of the reasons why we have to unite this country.

"We cannot allow for this to be happening. We cannot be like this. We cannot condone this."

Biden said he was yet to speak with the Trump but said he understands he's "doing well".

The president fell short of deeming the shooting an assassination "until we have all the facts".

"I have an opinion, but I don't have any facts," he said.

Trump's eldest son, Donald Trump Jr, posted a photo on X of Trump, his fist raised and his face bloody in front of an American flag, with the words: "He'll never stop fighting to Save America."

Prime Minister Anthony Albanese issued a statement this morning describing the incident as "confronting".

"The incident at former President Trump's campaign event in Pennsylvania today is concerning and confronting," Albanese said.

"There is no place for violence in the democratic process.

"I am relieved to hear reports that former President Trump is now safe."

Before Saturday's apparent attempted assassination of former President Donald Trump, there have been multiple instances of political violence targeting US presidents, former presidents and major party presidential candidates.

Former US president Donald Trump has been rushed from a stage with blood on his face after he was shot in the ear at a campaign rally in Pennsylvania.

Two people, including the suspected shooter, have been confirmed dead following the incident, which is being investigated as an attempted assassination of the former president and presumptive Republican nominee.

Here is what we know so far.

What happened?

Trump was showing off a chart of border crossing numbers during a rally attended by about 50,000 people before the Republican National Convention about 6.10pm on Saturday (local time) when shots began.

As Trump was talking, a popping sound was heard, and the former president put his right hand up to his right ear, as people in the stands behind him appeared to be shocked.

As the first pop rang out, Trump said, "Oh," and grabbed his ear as two more pops could be heard and he crouched down. More shots are heard then.

Someone could be heard saying near the microphone at Trump's lectern, "Get down, get down, get down, get down!" as agents tackled the former president.

They piled atop him to shield him with their bodies, as other agents took up positions on stage to search for the threat.

Screams were heard in the crowd of several thousand people.

Afterward, voices were heard saying "shooter's down" several times, before someone asked, "Are we good to move?" and "Are we clear?" Then, someone orders "Let's move."

He could be heard on the video saying at least twice, "Let me get my shoes, let me get my shoes," with another voice heard saying, "I've got you, Sir."

Trump got to his feet moments later and could be seen reaching with his right hand toward his face. There appeared to be blood on his face.

He then pumped his fist in the air and appeared to mouth the word "Fight" twice his crowd of supporters, prompting loud cheers and then chants of "USA. USA. USA."

The crowd cheered as he got back up and pumped his fist.

His motorcade left the venue moments later. Video showed Trump turning back to the crowd and raising a fist right before he is put into a vehicle.

Police began vacating the fairgrounds shortly after Trump left the stage in what local officers described as a crime scene.

What is Donald Trump's condition?

Blood was seen appearing to come from Trump's ear.

About 2.5 hours after the attack, Trump posted a message on his Truth Social account revealing he was shot by a bullet that pierced the upper part of his right ear.

"I 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. GOD BLESS AMERICA!" he wrote.

Trump thanked the Secret Service and all law enforcement for their rapid response.

"Most importantly, I want to extend my condolences to the family of the person at the Rally who was killed, and also to the family of another person that was badly injured."

"It is incredible that such an act can take place in our Country. Nothing is known at this time about the shooter, who is now dead," he wrote.

A spokesman for Trump, Steven Cheung, earlier released a statement saying the former president was "fine".

Who fired the shots?

Hours after the shooting the FBI named Thomas Matthew Crooks, 20, of Bethel Park, Pennsylvania, as the subject involved in the assassination attempt.

The agency said the investigation remains active and ongoing.

Few other details are known about Crooks, who was killed by Secret Service agents, but he was not an attendee at the rally.

"Nothing is known at this time about the shooter, who is now dead," Donald Trump earlier posted on his social media platform, Truth Social.

Speaking at a press conference this afternoon, FBI Deputy Commissioner of Operations Lieutenant Colonel George Bivens said authorities were yet to identify the initial shooter and the motive behind the attack, but would not rule out whether the gunman acted alone.

"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," he said.

Who has died?

Goldinger said the suspected gunman was dead and at least one rally attendee was killed.

He said that in addition to the spectator who was killed, two other attendees were taken to a local hospital and in critical condition.

Authorities said this afternoon they were not prepared to release the identities of the civilians killed or injured, other than the former president.

"I would confirm for you that we did have one individual killed and I heard about two victims, there were three in total besides the former president. Two critically wounded, one killed."

"There was one victim of the shooter who was killed. Then the shooter was killed."

Authorities did confirm all three victims were adult and male.
