Image source, ReutersThird-party US presidential candidate Robert F Kennedy Jr, who is running against both Donald Trump and Joe Biden in November's election, has called for Americans to "start treating each other with respect" in the political arena.
"My message to people is we need to all renounce violence. And we need to renounce not just violence but the hatred and vitriol," Kennedy told US outlet NewsNation.
Kennedy's father, Robert F Kennedy, was shot and killed as a presidential candidate in 1968. His uncle John F Kennedy was shot and killed when he was US president in 1963.
"I understand the implications that this has for our country - and probably as well as anybody does," he said.

Andy Biggs, a Republican congressman from Arizona, has told me he believes rallies - a core aspect to any political campaign - will be different after today.
"I will just tell you that my guess is that when you do a rally from now on, it's going to be an indoor venue where you have more control than what we've seen at these outdoor venues," he told me.
The area where Trump held his Pennsylvania rally was open and outdoors, with buildings in the vicinity.
Biggs noted a push in the past by some Democrats to strip Secret Service protections for those convicted of a felony, external - legislation that would have affected Trump given his criminal record.

Representative Ronnie Jackson, a Texas Republican, told Fox News in an interview that his nephew was at the rally and was grazed in the neck by a bullet.
He told the network he'd set up special access for his family to attend the rally in Pennsylvania. They were sitting in a "friends and family" section to Trump's right when they started to hear gunfire, he says.
Jackson says his nephew was "in the line of fire" and was bleeding from the neck. His family realised it was a bullet after seeing someone a few rows behind them had been shot, he says.
They went to a medical tent and saw another injured person with critical injuries to their head, Jackson says.

The extraordinary images of a defiant Donald Trump pumping his fist in the air, with blood on his face, being rushed off the stage by the Secret Service are not just history making – they may well alter the course of November's presidential election.
This shocking act of political violence will inevitably have an effect on the campaign.
The picture was quickly posted on social media, external by his son Eric Trump with the caption: “This is the fighter America needs."
President Joe Biden appeared on TV shortly after the shooting and said there was no place in America for political violence like this. He expressed concern for his Republican opponent and said he hoped to speak with him later tonight.
Biden’s election campaign paused all political statements and is working to take down its television ads as quickly as possible, clearly believing that it would be inappropriate to attack Donald Trump at this time and instead concentrating on condemning what’s happened.
Politicians from across the political spectrum – people who agree on very little else – are coming together to say violence has no place in a democracy.
Former Presidents Barack Obama, George W Bush, Bill Clinton and Jimmy Carter - in a statement issued via the Carter Center - were all quick to denounce the violence and said how relieved they were that Trump was not seriously hurt.
But some of Trump’s closest allies and supporters are already blaming Biden for the violence, with one Republican congressman accusing the president of “inciting an assassination” in a post on X.
Senator JD Vance, who is thought to be on the shortlist to become Trump’s vice-presidential candidate, said the rhetoric from the Biden campaign led directly to this incident.
Other Republican politicians are saying similar things, which will almost certainly be condemned by their opponents as incendiary at a dangerous time in American politics.
Already we can see the battle-lines being drawn in what may become a very ugly fight over a deeply shocking incident. This will reshape the election campaign.
The suspect fired from between 200ft and 300ft away on an elevated shed with an AR-style rifle, multiple law enforcement officers have told the BBC's US partner CBS.
