Donald Trump arrived at the Republican National Convention in Milwaukee for his first public appearance since he survived an assassination attempt two days ago
He had a large bandage on his right ear, which was injured when an attacker opened fire at a political rally
The leading Republican candidate became the party's official nominee earlier today, after a formal counting of the delegates at the convention
The former president named JD Vance, the senator from Ohio, to be his running mate and vice-president if he returns to the White House
Vance was once a Trump critic, but has since become one of the candidate's most trusted defenders on Capitol Hill and in the media
Trump also enjoyed a big legal win earlier today, after a judge in Florida threw out the classified documents case against him
Meanwhile, the fallout from Saturday's shooting continues - the US Homeland Security secretary says the gunman should never have had a direct line of sight

"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 posted on his Truth Social account.
"Much bleeding took place, so I realised then what was happening."
The shooting is being investigated as an attempted assassination, law enforcement sources tell the BBC's US partner CBS News.
Witness says he saw gunman on roof
One witness has told the BBC's Gary O'Donoghue that he saw a man crawl onto a roof with a rifle, approximately "five to seven minutes" into Trump's remarks.
"We noticed a guy crawling... up the roof of the building beside us, 50 ft away from us," he said.
"We're pointing at the guy crawling up the roof," he said, describing how he and his friends tried to alert law enforcement to the man's presence.
Our US news partner, CBS, is quoting two law enforcement sources who say the attacker was armed with a rifle and stood outside a cordoned-off area at the rally, about 200 yards (182m) from Trump.
The officials say the suspect was stood on an "elevated structure".
They were killed by a member of the US Secret Service counter-assault team, CBS reports.

Another witness to the violence in Butler tells the BBC she heard "pop, pop, pop" sounds before people started running at her.
"I heard the sounds. I heard the gunfire," she said.
She said the scene was chaotic with people in the back of the venue immediately running to the exits.
The witness said she wasn't surprised a shooting occurred because of the current political climate.

Donald Trump Jr, the former president's eldest son, has just released a statement.
“I just spoke to my father on the phone and he is in great spirits. He will never stop fighting to save America, no matter what the radical left throws at him," he said.
He was not in attendance at the rally, an aide confirmed to CBS News, the BBC's US partner.

Warren and Debbie, both of Butler, Pennsylvania, were at the venue when the shooting took place.
They said they were to the right of Trump when they heard at least four gunshots.
They said they both got on the ground as Secret Service came through the crowd, shouting for the attendees to get down.
From their vantage point, they said people remained calm.
"We couldn't believe it was happening," Warren said.
Debbie said a little girl beside them was crying that she didn't want to die and saying "how is this happening to us?"
"That broke my heart," Debbie said.
"I'm always afraid he's going to be assassinated," she added.

Washington correspondent at the scene
It's clear from the eyewitnesses I've spoken to that the shooting may well have come from a one-storey building off to the right of the stage where Donald Trump was speaking here in Butler.
It's a building with a white roof, and one witness told me that he saw a man crawl onto that roof with a rifle and he then attempted to tell law enforcement about the man. Then, a few minutes later what appeared to be gunfire rang out.
Several witnesses have confirmed to me that's where they believe the shooting came from.
Bear in mind the situation is still fluid and the BBC cannot fully verify these early witness reports.
The witnesses who have been speaking to us have been emotional when recalling the scene of panic, with everyone hitting the ground and watching Trump leave with blood on his face.
There are many questions still to answer, but today is undoubtedly an incredibly shocking day in America.

He said he hoped to speak with Donald Trump later tonight, adding that he had been thoroughly briefed on what happened. "I have tried to get a hold of Donald. He's with his doctors," Biden said.
"We cannot allow for this to be happening. We cannot be like this. We cannot condone this," he added.
Earlier, a campaign official said the Biden re-election campaign was pausing all outbound communications and working to pull down television ads as quickly as possible.
President Biden says federal agencies are involved in investigating the shooting.
A reporter asks if he believes it was an assassination attempt.
"I want to make sure we have all the facts," he said.
"There's no place in America for this kind of violence. It's sick, it's sick," Biden says.

A group of witnesses told BBC News the noises sounded like firecrackers at first.
"We could see the smoke off the ground, but they kept coming so we all hit the ground," one said.
They recounted how everyone around them ducked, but some started running after the noises.
"It was just so surreal. I've never heard anything like that in my life," one witness said.

President Joe Biden released a statement on the apparent shooting at Donald Trump's rally, saying he was grateful to hear Trump was okay.
"I have been briefed on the shooting at Donald Trump’s rally in Pennsylvania. I’m grateful to hear that he’s safe and doing well," he said.
"I’m praying for him and his family and for all those who were at the rally, as we await further information. Jill and I are grateful to the Secret Service for getting him to safety.
"There’s no place for this kind of violence in America. We must unite as one nation to condemn it."
Many reactions to the incident in Pennsylvania have come from Twitter/X. Here's one from the guy who owns it.
Elon Musk endorsed Donald Trump minutes after he was rushed from the stage at his rally.
The billionaire wrote: "I fully endorse President Trump and hope for his rapid recovery."
He later posted a photograph of Trump with the message: "Last time America had a candidate this tough was Theodore Roosevelt."

"As one whose family has been the victim of political violence, I know first-hand that political violence of any kind has no place in our society. I thank God that former President Trump is safe," Ms Pelosi wrote on X, external/Twitter.
Pelosi's husband suffered a fractured skull and other injuries after a man - who was looking for her - broke into her California home with a hammer.
Pelosi said she was praying for all of those at the rally.

Two witnesses who were in the rally venue in Butler County said they were in disbelief.
Jen and Theresa told BBC News they heard about six to eight gunshots.
"I heard pops, there was two pops with a delay. I knew right away it was gunfire... it was probably just maybe 30-45 seconds after that, [that] people just started panicking," Theresa said.
They said they didn't see anyone injured, but Secret Service agents rushed people out of the venue.
"That was the scariest part from our vantage point," Theresa said, recalling how they both got down on the ground before exiting the venue.

The suspect in the incident at Trump's rally is dead, along with an audience member, local district attorney Richard Goldinger has told the Associated Press and local media.
CBS, the BBC's news partner in the US, also reports that secret service agents "engaged" the suspect. Two law enforcement sources told CBS the male suspect is dead.

Within seconds of the news breaking, social media was filled with unsubstantiated rumours.
On X/Twitter, the word “staged” started trending - mostly pushed by Trump opponents speculating that the event was somehow manufactured to help the former president’s campaign.
To be clear - there’s no evidence that’s the case. But even the most far-fetched guesswork can get traction in a febrile atmosphere.
The rumours parallel long-standing conspiracy theories among Trump supporters of “false flag” mass shooting attacks and “deep state” assassination plots against Trump.
Those are also lacking in evidence, but will certainly get a boost by today’s events.
After a major and unexpected event like this one, reports and rumours always fly.
But remember: Many of them will be wrong.
