His accusation came after a Trump rally in Chicago on Friday was called off amid scenes of violence that included fistfights and people throwing bottles in what many believe is a turning point in the campaign if not American politics.
Speaking on CNN later, Trump called protesters at his rallies “bad people that are looking to do harm to our country.”
“When these people come into (my rallies), you know, everybody thinks I’m a bad guy,” he said.
“If my people went into one of(Sanders’s) rallies, they’d say, ‘oh, this is a terrible thing.’ They would be arrested and all sorts of things would happen to them.”
Sanders on Sunday denied his campaign had directed supporters to protest Trump rallies.
“Trump’s words must be taken with a grain of salt because I think as almost every knows, this man cannot stop lying about anything,” he said, adding that Trump is inciting violence because poll numbers show he would not win a general election.
“People in America know that we cannot have a president like Trump who insults Mexicans, who insults women, who insults Muslims,” he said, also on CNN. “People are catching on to Donald Trump. That’s why he’s getting reckless.”
Other politicians across the political spectrum have called on Trump to tone down his rhetoric, saying he is fanning division by exploiting anger among the electorate.
Marco Rubio, his rival for the Republican nomination who is trailing in third place, called Trump’s actions “reckless and dangerous.”
“If we reach a point in this country where we can’t have a debate about politics without it getting to levels of violence and anger,” he told CNN, “we’re going to lose our republic.”
