As we've been reporting, Thomas Crooks, the 20-year-old gunman who was shot dead at the scene, was rejected from his high school rifle team.

A classmate has told ABC News that Crooks was asked not to come back to the team after a preseason session.

“He didn't just not make the team, he was asked not to come back because how bad of a shot he was, it was considered like, dangerous," Jameson Myers said.

Another member of the team recalled how Thomas Crooks "shot terrible" and "wasn't really fit for the rifle team".

The school district said there was no record of Crooks trying out for the team and he "never appeared on a roster".

Crooks did, however, belong to a local shooting club - the Clairton Sportsmen's Club - for at least a year.

Buckingham Palace has confirmed that King Charles III wrote privately to former President Donald Trump yesterday and that this message has been delivered via the British embassy in Washington.

The contents of the letter have not been made public.

The BBC understands that the sentiments in the letter are in keeping with those communicated by the prime minister.

“I wasn’t surprised that something like this happened given the state of American politics,” Matthew Schmidt, associate professor of national security and political science at the University of New Haven in Connecticut, tells BBC 5 Live Breakfast.

Schmidt adds he was shocked by the assassination attempt but that the current political climate was conducive to violence:

Extreme politics used to be the norm in the US, then stopped during the Cold War and is now reverting back, Schmidt says.

Once every four years the Republican and Democratic parties host conventions to formally select their respective presidential candidate and prepare for the final stretch of campaigning.

The conferences include high-profile speakers, as well as a prime-time speech from the nominee.

During the convention, the delegates from each state pledge their support to the candidate of their choice and approve a platform.

It is merely a formality for Trump as he is the party's presumptive nominee having won 2,265 delegates in the primaries, which is enough for the nomination.

The 2024 Republican National Convention (RNC) will kick off later today and run until Thursday. The Democrats will hold their convention next month in Chicago.

Trump is expected to speak on Thursday night. Other speakers reportedly include Marjorie Taylor Greene, a Georgia congresswoman, Florida Governor Ron DeSantis and former Fox News host Tucker Carlson.

One of the biggest moments of the conference will be when Trump unveils his vice-presidential candidate, but as the dust settles from the assassination attempt, it is unclear when he will announce who he has chosen as his running mate.

Veteran Republican congressman Pete Sessions says the attempted assassination of Trump was a "failure" of law enforcement, which is "unacceptable" and "most destressing" – saying there are "lots of questions to ask".

Trump was "saved by the grace of God", he tells the BBC's Today programme.

Asked what Trump's tone will be when he speaks at the Republican convention – where he will be formally nominated as the party's presidential candidate later this week – Sessions says he thinks it will be on the need to "move forward" and "change the dialogue".

"We have been led down this pathway that it's okay to verbally bludgeon each other," Sessions says, adding "no country can survive much of this."

"I think he should be for fix, not fight," Sessions says of Trump's tone going forward.

Here's a bit more from Wisconsin representative Glenn Grothman’s interview with the Today programme.

Grothman goes on to say that the vast majority of the media in the US is not impartial, left-wing and "unnecessarily inflammatory".

"So if a young person, a 20-year-old would read this sort of thing, it doesn't surprise me that he may feel 'oh my goodness I had better shoot Donald Trump, the next Adolf Hitler is about to take over the United States'," Grothman adds.

Asked about the role of the Secret Service and the criticism it has received since Saturday, the chairman of the subcommittee on national security says he doesn't understand why the roofs of the buildings around Trump's rally were not being monitored.

He then adds that the current director of the secret service is "unnecessarily woke" and "spends a great deal of time to get so many women, for example, in the secret service as possible rather than spending their time making sure they're doing a good job".

Donald Trump has said he was "supposed to be dead", calling the assassination attempt a "surreal experience".

"I’m not supposed to be here, I’m supposed to be dead,” said Trump, speaking to the New York Post while en route to Milwaukee for the Republican National Convention.

Trump wore a white bandage that covered his right ear but his aides did not allow any photographs to be taken, said the Post.

“The doctor at the hospital said he never saw anything like this, he called it a miracle," Trump added.

We've just been hearing from former FBI special agent Ken Gray on the Today programme.

So far, the FBI has said it is investigating the shooting as a potential act of domestic terrorism, although the motive is still unclear.

Gray says the shooter's ability to get as close as he did shows there was a "failure in security", and that the FBI is conducting an investigation over whether or not it was sufficient for this kind of rally.

He explains that prior to the event, security starts with a site survey where they consider possible threats - where they could come from and how to extract someone from the crowd.

The retired agent criticises the "awful long time" it took for the security services to get Trump away from the scene, suggesting it could have left another opportunity if there was a second shooter.

Republican Congressman Glenn Grothman tells the BBC that left-wing media outlets are partly to blame for the assassination attempt on Donald Trump.

"I think it is the inflammatory rhetoric, both from the left-wing politicians in the United States and even more the left-wing media.

"They have set up Donald Trump to be some sort of boogeyman, a fascist, a dictator and as a result I think there is hatred for him beyond the normal hatred the left has for the Republicans," the Wisconsin representative tells BBC Radio 4's Today programme.

Pushed on Trump using similar rhetoric - for example surrounding the attack against former Speaker of the House of Representatives Nancy Pelosi's husband in 2022 - Grothman says that there is no comparing what Trump sometimes says, which he claims is mostly meant humorously, and the demonisation he faces.

He says both politicians and the press are "calling him a dictator, saying he will be the end of democracy in America", which he says is "ridiculous" because Trump was already president for four years.

"We know exactly what kind of president he will be," Grothman says.

It's now been around 32 hours since a gunman attempted to assassinate Donald Trump while the former president spoke at a rally in Pennsylvania.

Trump has been speaking to newspapers about the experience and what he plans to say at a major speech this week. Here's the latest:

• Trump has arrived in Milwaukee, Wisconsin, for the Republican National Convention – which is going ahead as planned – and where he will be formally nominated as the party's candidate later this week
• In an interview with the Washington Examiner, he said he now planned to give a different kind of speech, and that he had been given an opportunity to "bring the country together", rather than focus attacks on his rival, Joe Biden
• Trump, who was shot in the ear, also spoke about the experience, saying: "I knew the world was looking. I knew that history would judge this". He told the New York Post he was "supposed to be dead"
• President Biden, making a rare address from the Oval Office, called on the country to stand together and settle political differences "peacefully" at the ballot box
• He also reiterated that little was known about the suspected gunman – who has been identified as 20-year-old Thomas Matthew Crooks – following a wave of misinformation online
• Biden will return to the campaign trail on Tuesday after initially suspending campaign activities following the attempt to assassinate Trump
• The Secret Service - the agency tasked with keeping Trump safe - is under scrutiny from multiple agencies and departments, with the FBI saying it's "surprising" a gunman was able to open fire on the stage before being killed

We'll continue to bring you updates and analysis throughout the day.

The FBI has issued an end of day update on its investigation into the attempted assassination on Trump, but it offers little in terms of new details.

The bureau has reiterated that it has not identified why Thomas Matthew Crooks may have attempted to assassinate the former president, but that it is "working to determine the sequence of events and the shooter’s movements prior to the shooting" and is reviewing the evidence collected.

"While the investigation to date indicates the shooter acted alone, the FBI continues to conduct logical investigative activity to determine if there were any co-conspirators associated with this attack," it says in the statement.

Crooks had no known past offences, and the gun he used in the shooting was purchased legally.

"There are no current public safety concerns," the FBI says.

We still don't know much about the man behind the shooting, 20-year-old Thomas Matthew Crooks.

Crooks, who was shot dead at the scene, was working as a kitchen aide at a nursing home near his hometown in Pennsylvania, where he graduated from high school in 2022.

His peers and teachers have described him as respectful, bright and quiet - with his school counsellor telling Reuters he never knew Crooks to be political.

US media have reported he was a registered Republican, citing state voter records, but he is also reported to have donated $15 to liberal campaign group ActBlue in 2021.

The FBI said on Sunday that it did not find any threatening language on Crooks' social media profile, nor have they found any history of mental health issues.

They said they believe the gun used - an AR-style 556 rifle - had been legally purchased by his father, but that the shooter acted alone.

In line at a local coffee shop in Pennsylvania, I met a former classmate of Thomas Matthew Crooks, the 20-year-old gunman who was shot dead at the scene.

The classmate, who asked to remain nameless "because of the current political situation", said he attended the same Bethel Park high school as Crooks, but barely remembered him.

"He was there but I can't think of anyone who knew him well," the classmate said. "He's just not a guy I really think about. But he seemed fine."

Jameson Myers, a former member of the Bethel Park High School varsity rifle team who graduated alongside Crooks in 2022, told CBS that he had been rejected from the team.

Myers remembers Crooks as seemingly a "normal boy" who was "not particularly popular but never got picked on or anything".

"He was a nice kid who never talked poorly of anyone and I never have thought him capable of anything I’ve seen him do in the last few days."

Donald Trump has arrived in Milwaukee, Wisconsin for the Republican National Convention.

Walking down from the airplane with aides, the former president punched his fist into the air - the same gesture he made right after he got shot on Saturday.

Donald Trump has arrived in Wisconsin for the Republican National Convention.

The party conference in Milwaukee is going ahead as planned despite Saturday evening’s shooting at a rally in Pennsylvania.

Trump posted on social media that he had considered delaying his trip by two days, “but have just decided that I cannot allow a 'shooter,' or potential assassin, to force change to scheduling, or anything else”.

The attack on Trump has put a heightened focus on the safety and security of the event, which begins on Monday.

But Audrey Gibson-Cicchino, RNC coordinator for the US Secret Service, said during a Sunday afternoon news conference in Milwaukee that there would be no changes to the security plan.

Some 50,000 people are expected to attend the four-day event as the party makes its case to voters ahead of November’s general election.

Trump is also expected to reveal his running mate at the convention, and that person's speech will most likely take place on Wednesday.

More information about the convention can be found here.

President Biden will receive a briefing from homeland security and law enforcement officials on Monday, and then give an interview to NBC's Lester Holt in the afternoon.

After that, he plans to resume campaigning, a White House schedule shows.

Biden suspended campaign activities on Saturday after the attempt to assassinate Trump.

In the NBC interview, Biden is expected to expand on the vision he presented in his Oval Office address on how to "put to an end to political violence in this country once and for all," according to a campaign official.

Biden will leave for Las Vegas and is on Tuesday set to speak to the NAACP National Convention, after sitting down with Ed Gordon of cable channel BET, and the UnidosUS annual conference the day after.

Wednesday is also when Donald Trump's as yet unannounced running mate is expected to address the Republican convention in Wisconsin.

• President Biden has addressed the nation from the Oval Office, calling on the country to stand together and settle political differences "peacefully" at the ballot box
• Biden also has reiterated that little is known about the suspected gunman - who has been identified as 20-year-old Thomas Matthew Crooks - following a wave of misinformation that has taken hold online
• FBI agents have said they are investigating the motive behind the attack, and that they believe the shooter acted alone

• President Joe Biden spoke with Trump on the phone hours after the incident and called the assassination attempt "sick"
• Political advertisements for the president's campaign are being pulled from television in light of the attack
• The Secret Service - the agency tasked with keeping Trump safe - is under scrutiny from multiple agencies and departments, as the FBI says it's "surprising" a gunman was able to open fire on the stage before being killed
• Trump, who says he is fine after a bullet pierced the upper part of his ear, today touched down at the Republican National Convention in Milwaukee, where he will be formally nominated as the party's candidate later this week
• Prime Minister Keir Starmer has joined a chorus of world leaders offering his condolences and "best wishes" for a speedy recovery
• One man died in the shooting and two others were injured

This is a constantly evolving and complex story, but we'll keep you up to speed with the latest as we learn it.

A senior Democratic senator has told the BBC's Newshour programme that Republicans trying to blame Joe Biden's campaign rhetoric on the assassination attempt of Donald Trump is "odious".

Tim Kaine dismissed the idea the Democrats are at all responsible for the shooting and said what the attack really underscored is America's longstanding gun problem.

"You need to analyse what it is about America that creates such a sickness of gun violence," he said.

"We are such an outlier in the world. And this is kind of the most visible effort - an effort to assassinate a political leader.

"There is so much that is so good about the United States but we have to be candid enough to look in the mirror.

"How does a 20 year old get an automatic weapon that is capable of wreaking this carnage?"

"Everything changed yesterday. The world changed."

Corey Lewandowski, who was Donald Trump’s campaign manager in 2016, says the current campaign has been forced to “rethink everything that goes on, from the president’s speech through to the vice-presidential nominee’s speech, to everybody in between”.

He says the assassination attempt “fundamentally changed the dynamic of this race”.

He added that Trump was “the only person who is going to make the final decision on the vice-president” and he couldn’t say if the decision on who Trump would pick had changed from yesterday to today.

Former President Donald Trump has given one of his first interviews since the attempt on his life on Saturday night, saying he has completely rewritten his convention speech to focus on a message of "unity" instead of criticising Joe Biden.

"The speech I was going to give on Thursday was going to be a humdinger,” he told the Washington Examiner.

“Had this not happened, this would’ve been one of the most incredible speeches,” he also said, adding that it would have been aimed mostly at the President Biden's policies.

“Honestly, it’s going to be a whole different speech now. It is a chance to bring the country together. I was given that chance.”

Trump also said that the "reality" of what happened on Saturday "is just setting in," and described the moment he looked up at the crowd after realising he had been shot.

“The energy coming from the people there in that moment, they just stood there; it’s hard to describe what that felt like, but I knew the world was looking. I knew that history would judge this, and I knew I had to let them know we are OK,” he told the Examiner.

The former president touched down in Milwaukee just hours ago, where he'll attend the Repulican National Covention this week and be formally nominated as the party's candidate. He's also expected to reveal who will be his running mate in the election.
