 CLEVELAND (AP) — In a Republican presidential primary filled with extraordinary moments, a 24-hour stretch that began Friday night stands above them all. 
  
 Opponents of Donald Trump were so committed to keeping him from speaking in Chicago that they aggressively clashed with supporters, forcing the GOP front-runner to abruptly cancel his rally before it even began. 
  
 The next morning, two of the candidates still fighting to defeat Trump, Florida Sen. Marco Rubio and Ohio Gov. John Kasich, said they were so disgusted by the chaos that they may not support the billionaire businessman if he clinches their party's nomination. 
  
 And when Trump appeared at another rally Saturday morning in Ohio, he was suddenly pulled midspeech into a protective ring of U.S. Secret Service agents charged with guarding his life after a man rushed the stage. 
  
 "Thank you for the warning," Trump told the crowd after he resumed his speech. "I was ready for 'em, but it's much better if the cops do it, don't we agree?" 
  
 Each moment has virtually no precedent in modern presidential politics. Taken together, they exposed anew the remarkable anxiety ripping through a country dealing with profound economic and demographic changes, as well as the anger roiling inside one of America's great political parties. 
  
 For those cringing at the discord and Trump's unanticipated political rise, there were no easy answers Saturday. 
  
 While not mentioning Trump by name, Republican National Committee Chairman Reince Priebus said in a statement Saturday that political leaders in both parties have a responsibility to ensure that the "discourse we engage in promotes the best of America." 
  
 "While we have differences, the exercise of our right to free speech should be just that: speech," Priebus said. "Violence is never the answer. Violence only begets violence." 
  
 Republican traditionalists kept whispering in private conversations about long-shot options for stopping Trump, either at a contested convention or by rallying around a potential third-party option. Trump, meanwhile, could put the Republican nomination out of reach to others in Tuesday's slate of five delegate-rich primaries. 
  
 Trump's rivals have spent months tiptoeing around his provocative comments for fear of alienating his impassioned supporters. Even in Thursday night's debate, all three of his remaining rivals — Rubio, Kasich and Texas Sen. Ted Cruz — sidestepped a question about whether outbursts of violence at Trump's rallies and his statements encouraging supporters to aggressively take on protesters concerned them. 
  
 But the images spilling out of Chicago, with young people angrily confronting each other, often divided by racial lines, appeared to be too much. 
  
 In an interview with The Associated Press, Rubio said he may not be able to support Trump if he's the GOP nominee, citing the way he's "dividing both the party and the country so bitterly." 
  
 The Florida senator, who won the party's caucuses in Washington D.C. on Saturday, wouldn't say whether he'd look for a third-party candidate to support if Trump does become the Republican standard-bearer. He added, "The fact that you even have to ask me the question shows why (Trump) is a problem." 
  
 Kasich, who has largely avoided tangling with Trump until now, said the real estate mogul has created a "toxic environment" that makes it "extremely difficult" to envision supporting him as the Republican nominee. 
  
 "To see Americans slugging themselves at a political rally deeply disturbed me," Kasich said while campaigning in Cincinnati. "We're better than that." 
  
 Only Texas Sen. Ted Cruz, who is closest to Trump in the delegate count, said he would unequivocally support the businessman if he emerges from the primary victorious. Still, Cruz — eager for Rubio and Kasich to get out of the race after their home-state primaries on Tuesday so he can take Trump on in a head-to-head contest — blamed his rival for encouraging the kind of "nasty violence" that occurred in Chicago. 
  
 President Barack Obama, speaking at a Democratic fundraiser in Dallas, said those who aspire to lead the country "should be trying to bring us together and not turning us against one another," and he urged leaders to "speak out against violence." 
  
 "If they refuse to do that, they don't deserve our support," he said. 
  
 With his delegate lead mounting, there's little evidence that Trump sees any reason to alter an approach that includes encouraging his supporters to aggressively — and sometimes physically — stop protesters from interrupting his raucous rallies. 
  
 Instead, Trump said at a rally Saturday afternoon in Cleveland, which was also interrupted several times by dozens of protesters, that he thought all the disruptions would help him. 
  
 "It just makes all of our friends and supporters more angry. We're going to go to the polls on Tuesday," he said, predicting a "resounding victory." 
  
 Nor did Trump moderate elsewhere. On Twitter, Trump said the man who rushed the stage at his Ohio event had ties to the Islamic State, citing a video that experts said could not possibly be linked to the radical militant group. 
  
 He also alleged online that Rubio and his Republican allies in Florida were trying to "rig the vote" in the Florida senator's favor and that he'd asked law enforcement to investigate. Florida elections officials said they had not heard of any such problems and had received no formal complaints. 
  
 Indeed, Trump appeared eager to paint himself as the victim of the extraordinary events. He complained the well-organized protesters in Chicago intent on keeping him from speaking had violated his First Amendment rights, and questioned why no one was asking Bernie Sanders to defend the actions of his backers. 
  
 Several of the protesters in Chicago said they are supporters of the Democratic candidate. 
  
 "They're Bernie fans!" Trump said in Cleveland. "Hey, Bernie, get your people in line, Bernie!"

 USSS did an excellent job stopping the maniac running to the stage. He has ties to ISIS. Should be in jail! https://t.co/tkzbHg7wyD?ssr=true — Donald J. Trump (@realDonaldTrump) March 12, 2016 
  
 "It was probably ISIS or ISIS-related," Trump said at a rally in Kansas City, Mo. "They find the guy is playing all sorts of, just– let's say music that you wouldn't be liking, dragging an American flag along the sidewalk, making all sorts of gestures ... and he's probably or possibly ISIS-related." 
  
 "This guy should be in jail right now," he said. "This is a guy who was looking to do harm." 
  
 According to Heavy.com, the flag protest video of Dimassimo was used in a hoax ISIS video, seemingly created by an Internet troll who also operates an anti-Dimassimo Facebook page. 
  
 Dimassimo jumped over a barrier and made a run for the stage before he was tackled by the Secret Service at a Trump rally in Dayton, Ohio. He was charged with disorderly conduct and inducing panic. |||||
A: 
Donald Trump's rallies are not for the faint of heart: After security concerns police later said were unfounded canceled one rally in Chicago, and the candidate was rushed by a protester the next day in Ohio, Trump offered up a theory on his would-be assailant at yet another rally Saturday in Kansas City, reports the Hill. "It was probably ISIS or ISIS-related," Trump told a rally later Saturday. "They find the guy is playing all sorts of, just—let's say music that you wouldn't be liking, dragging an American flag along the sidewalk, making all sorts of gestures ... and he's probably or possibly ISIS-related." It is, as the AP reports, "a 24-hour stretch that ... stands above" a GOP primary "filled with extraordinary moments," and which has "virtually no precedent in modern presidential politics. The protester in question, the Hill notes, has been identified as Thomas Dimassimo, who has been charged with disorderly conduct and inducing panic. And future protesters should expect similar charges, Trump told the rally in Kansas City, reports the Heavy: "I hope these guys get thrown into a jail. They’ll never do it again, it’ll destroy their record. They’ll have to explain to mom and dad why they have a police record and why they can’t get a job. And you know what, I’m gonna start pressing charges against all these people. And then we won’t have a problem. ... I don’t want to ruin people’s lives. But the only way we’re gonna stop this craziness is if we press charges."
