Democratic presidential candidate Bernie Sanders hit back at Donald Trump for inciting violence and 'invited' the Republican's supporters to his events to 'see what a real honest politician sound like'.

Donald Trump had threatened to send his supporters to stage a violent rally at Bernie Sanders' next event.

The billionaire tweeted on Sunday: 'Bernie Sanders is lying when he says his disruptors aren't told to go to my events. Be careful Bernie, or my supporters will go to yours!'

The Vermont senator offered a reply back to the businessman, saying to bring them on.

'Send them. They deserve to see what a real honest politician sounds like,' a tweet from Sanders' campaign account read. It appears that the tweet has since been deleted.

It is the latest jibe in an ongoing head-to-head between Trump and Sanders after the GOP frontrunner claimed the protesters that shut down his event in Chicago 'represented Bernie'.

Sanders hit back on Saturday, branding Trump a 'pathological liar'.

Ten people were arrested following the Chicago brawl which left a police officer needing 20 stitches after being hit in the head by a bottle.

The violence in Chicago came hours after a black anti-Trump protester was beaten by a baying mob outside an event in St Louis.

Trump has been accused of encouraging supporters to make 'Nazi-like' hand salutes, a charge he vehemently denies, saying: 'People put their hands in the air at my events. There's nothing sinister about that.'

On Saturday, the real estate mogul defended his supporters, telling the cheering crowd in Ohio: 'My people are nice! They were taunted, they were harassed. A lot of those [protesters] represented Bernie, our communist friend.'

And added: 'With Bernie, he should really get up and say to his people, 'stop, stop.' Not me. Get your people in line Bernie!'

The billionaire businessman also tweeted Saturday: 'It is Clinton and Sanders people who disrupted my rally in Chicago - and then they say I must talk to my people. Phony politicians!'

But Bernie has been quick to discredit Trump's sensational accusations.

He said in a statement released Saturday afternoon: 'As is the case virtually every day, Donald Trump is showing the American people that he is a pathological liar.

'Obviously, while I appreciate we had supporters at Trump's rally in Chicago, our campaign did not organize the protests.'

He added: 'What caused the protests at Trump's rally is a candidate that has prompted hatred and division against Latinos, Muslims, women and people with disabilities, and his birther attacks against the legitimacy of President Obama.

'What Donald Trump must do now is stop provoking violence and make it clear to his supporters that people who attended his rallies or protest should not be punched, should not be kicked.'

And Sanders is not alone: Every GOP candidate took the Chicago meltdown as an opportunity to denounce Trump's 'violent rhetoric' as being the root cause of rally unrest.

Both Republican and Democratic politicians were united in their condemnation for Trump today, in the wake of bloody violence.

'Liar': President Obama said that Trump was a product of existing problems in the Republican party - that the candidate was just better at lying, insulting and being uncivil than his peers in the party

Trump's rivals, Ted Cruz, John Kasich and Marco Rubio all said that Trump was stirring up a hateful - even 'toxic' - environment in politics, while Democratic hopefuls Bernie Sanders and Hillary Clinton ripped into Trump's divisive attitude.

And even President Obama weighed in during a speech at a Democratic fund-raiser, saying that Trump was the inevitable result of what he described as a trend of lying and bullishness in the Republican party.

While Hilary Clinton said this morning: 'You know, we will always have our differences, won't we? That's what happens in a democracy like ours.

'But the ugly, divisive rhetoric we are hearing from Donald Trump and the encouragement of violence and aggression is wrong, and it's dangerous.

'If you play with matches, you're going to start a fire you can't control. That's not leadership. That's political arson.
