And now donald trump is calling for protesters to be arrested. I hope these guys get thrown into a jail. Ill never do it again. It will destroy their record. Theyll have to explain to mom and dad why they have a Police Record and why they cant get a job and you know what . Im going to start pressing charges against all these people. Okay . And then we wont have a problem. And Bernie Sanders responding today to trumps claims that sanders supporters are part of the problem. Disrupting trump events. At a rally in ohio, he has called you out. He says you ought to tell your supporters to stop coming and protesting at his rallies. What is your response . We have never, never once told anybody to do anything like that. The truth is, this guy really is a pathological liar. He says the first thing that comes to his mind. I guess hes referring to me as a communist. I think its terribly important that trump tell his supporters that in america you dont go around beating up people who are protesting or who have a different point of view. Hes got to start changing his rhetoric and not blame other people for the problems that he is causing. Trumps republican rivals criticizing trump on the campaign trail with just days before crucial primaries. Listen to how ted cruz, john kasich and marco rubio responded on saturday when asked whether they would still support trump if he were the republican nominee. My answer is the same, i committed at the outset. I will support the republican mommy, whoever it is. Makes it very extremely difficult. Lets just everybody take a deep breath and well see where it goes. I still, at this moment, continue to intend to support the republican nominee. But getting harder every day. And at this hour, were rolling out brandnew nbc wall street journal marist polls as the contests heat up in the delegate rich states of florida, ohio, and illinois. Donald trump leads the field here in florida by a nearly 2 to 1 margin over marco rubio in our latest poll. Trump leads in illinois, as well. But john kasich holds the edge in his home state of ohio. The governor hoping to clinch his first win. On the democratic side Hillary Clinton leads by a large margin here in florida, and in ohio where she leads Bernie Sanders by 20 points, in illinois clinton still leads but by a slimmer margin just six points separate the democrats there. Donald trump continuing to stoke controversy this morning, with a new tweet, quote, Bernie Sanders is lying when he says his disruptors arent told to go to my events. Be careful, bernie, trump writes, or my supporters will go to yours. That threat being lodged ahead of trumps three rallies in three states today, we begin with Hallie Jackson in bloomington, illinois, where donald trump will be speaking just a couple of hours from now. Hallie . Hey, there, kate. Yeah, people here bracing for possibly yet another chaotic day in bloomington. You can see the line forming behind me. Folks heading into this, what looks like an airplane hangar here. Trump is now talking tough against these protesters who interrupt his rallies. Promising to push for their arrests to, in his words, stop the craziness. New clashes in more cities at Donald Trumps rallies. Protesters, pepper sprayed during duelling demonstrations for and against trump in kansas city, and in cleveland, verbal arguments turning ugly. Go back to africa. Reporter in dayton this dramatic moment, secret service jumping onstage to surround trump, blocking him from a man trying to rush him. This new video showing a different angle. The candidate clearly startled. The protester, quickly arrested. I was ready for him. But its much its okay now. Reporter all right, kate so some technical difficulties. That said, the tweet youre talking about is now seeming to pick up some momentum online. Trump and Bernie Sanders essentially, you played some of the sound back and forth. Trump saying be careful bernie or my supporters will show up at your events. Ill tell you yesterday in dayton, ohio, we were at a rally in the morning and the first protester or one of the first protesters to be escorted out was yelling Bernie Clinton 2016. Youve heard those chants. Bernie himself has disavowed that or said hes not the one organizing that. His campaign is not the one organizing that. But certainly a story line to watch today with all of these candidates out on the campaign trail. The big question here, weve spoken with people who are rattled by the increasing violence at donald trump rallies, but, will any of it rattle the voters heading to the polls in places like ohio and florida, where you are . Yeah. And ive also spoken to voters, im sure you have, too, hallie, who are emboldened by all of this. Who want to go to trumps event tonight here in boca raton because they want to see it all and feel the energy of a trump rally. Thats exactly it. Its kind of a spectacle. Yeah. All right. Hallie jackson thanks so much. Lets bring in msnbcs tony decopele in westchester, ohio, where trump will hold a rally later this afternoon. Also trymaine lee is in kansas city. Let me start with you. Youve been out on the road, youre there, you were in missouri last night, and i know you know all about what happened in chicago, you got there just after that event on friday night. How do you compare what happened in kansas city last night to what happened friday in chicago. Where are we at on a sunday morning . Ill tell you what, in so many ways, its kind of like the trump tornado kind of rolled through the midwest. In chicago, and st. Louis, and then hit here on main street in kansas city. From the very beginning emotions were running high on both sides. But it had been relatively peaceful especially after what we saw in st. Louis where people were squaring up to fight each other, where some were bloodied and arrested. 32 in fact. In chicago we saw the bedlam out on the streets. In the very beginning this was kind of peaceful and calm. Then at some point something happened in the crowd. You saw Police Officers on horseback. Spraying pepper spray with some sort of irritant into the faces of some of the protesters. A few other fights about to break out. And people had to wonder, you know, when will this fire be contained . On both sides of it. And i spoke to a number of Trump Supporters who were kind of using some of the rhetoric that donald trump uses. Hes talking about the protesters as jobless, as on welfare, as you know, theyre not voting and theyre lazy. Using that kind of same, incendiary rhetoric. Again it wasnt as volatile as the events in st. Louis and chicago. But it was a tough sight. Its clear that this thing has gotten ugly and we saw that again last night. Just the rhetoric from both sides was pretty shocking. And tony, context is important here, obviously. Were showing clips of isolated incidents. But i want to ask what you you saw yesterday, one of the clips ive seen this morning i believe you shot with your cameras of people screaming at each other. Thats right, kate. That was outside the Cleveland International exposition center. Its an area outside the airport. A industrial area. No ones community. But two groups came, there were black lives matter protesters, and there were core Trump Supporters. Just following the event it heated up. There was that core contingent of protesters saying dumb trump. There was also contingent of trump reporters handing out fliers saying dont yell at the protesters, sing. They had the lyrics of america the beautiful on there. The people ive been talking to in ohio at the savannah center, which is a wedding venue in a suburban part of north of cincinnati, theyve got a much more positive message. Like yesterday theyre saying were going to have a very, very happy time here, be about supporting trump, not confrontational. And if protesters should arrive. By the way, theyve got an area across the street roped off, geese and protesters apparently going to enjoy that damp, swampy area across the street, theyre not going to engage. You heard trump say yesterday if protesters deinterrupt his event hes going to seek to press charges, hes going to quote ruin their lives. Some heat added to that threat today because hes going to get an endorsement on stage by the sheriff of this county. Kate . Trymaine, let me go back to you. Theres been a lot of talk about whether these protesters are organized. Whether moveon. Org for example might be rallying people to come out to donald trump events specifically. Whats your sense of the level of organization . There definitely is a level of organization, i think its more on the local grassroots level. Weve seen from city to city theyve experienced their own levels of unrest around police violence, et cetera. You look at the Ferguson Protesters whove been pushing on the ground and fighting and protesting for more than a year and a half now, you look at the fallout in chicago, with a long history of activisactivism, but built around the killing of Laquan Mcdonald by a police officer. Then you come to kansas city where theyve had issues with police. Theyre tapping into the energy and foundational structures already in place. So its not hard to imagine going state to state, the same way, after Michael Brown was killed, we saw the protests and activism and folks taking to the streets in different cities kind of loosely coordinated but again, i think what were seeing thats different than a ferguson the kind of coalition that youre seeing out here the young, old, black, white, hispanic especially. So you have folks holding up the mexican flag right next to folks holding up black lives matter signs and young, white activists who see trump as a fascist. Thats a little different. So if you are able to kind of go to the city and tap into those different organizations i think thats what youre seeing and thats where youve seen a lot of the power fuelled by the frustration. And tony, weve been talking this morning about this new tweet from donald trump, where he sort of suggests that maybe his supporters ought to show up at Bernie Sanders events. Are you getting the sense that there is kind of a Bernie Sanders crowd at trump events of disruptors, and maybe some trump people would head over to bernie events . There are certainly Bernie Sanders supporters coming to trump events. One of the protesters yesterday was a nurse from year the ohio West Virginia supporter. She drove all the way to cleveland to be there. Some of the protester who were immediately kicked out met in the parking lot not with even preengagement, they made some eye contact, had an understanding, decided to stick to the. Not that kind of organization, not professional certainly not. But there is a clash of movements here. The bernie revolution against the Trump Movement and i wouldnt be surprised if some trump backers do show up at bernie events in the future. Yeah, youll have to ask some of those folks in line whether theyre planning on doing any of that now that hes put that tweet out there. Tony dokoupil, thank you so much. And trymaine lee great to see you. Back in florida, marco rubio desperately needs a victory on tuesday. New nbc polling out this morning shows the florida senator 21 points down to donald trump here. Rubio will hold his first event of the day in the villages retirement community, and thats where we find nbcs Gabe Gutierrez. Gabe . Hi kate, good morning. Yeah, youre right. Rubio set to hold an event here this afternoon in the villages. And then hes stopping by to greet his volunteers in the orlando area. This morning, another round of media interviews but youre right, kate, this is a very uphill battle for marco rubio. Now according to this new nbc news wall street journal marist poll hes down 21 points in his home state. Rubio also commenting on whats going on on these donald trump rallies and hes saying that if donald trump is the nominee, that he fears the Republican Party could be defined for this for years to come. Hes also laying part of the blame, just part of the blame. He says theres no doubt that president obama has contributed to the divisive culture in america. But, he made it clear that he doesnt believe obama is responsible for any of the violence that happened over the last two days. But just generally, that obama has contributed to this divisive culture. Now the question will be, will rubio be able to gain any traction here in florida over the next two days . A lot of critics have said that he hasnt had enough of a ground game here and he just isnt drawing simply isnt drawing the large crowds that weve seen donald trump draw. Not even close. Rubios events draw several hundred people. Of course donald trump drawing thousands to each event. Kate . All right Gabe Gutierrez following marco rubio across the state of florida today. Gabe, thanks so much. Now, lets turn to the democratic side. Hillary clinton and Bernie Sanders are battling for every vote, of course, with critical states set to weigh in on tuesday with a lot of talk about trade, and health care. Nbcs Kristen Welker is in cleveland, ohio. Kristen . Kate, good morning to you. Secretary clinton and senator sanders will be campaigning here in critical ohio today. But on saturday those violent protests loomed large. The rivalry between Hillary Clinton and Bernie Sanders is escalating. Both were temporarily unified saturday, blaming Donald Trumps rhetoric for stoking violent protests at his rally in chicago friday. That is not leadership, it is political arson. Violence at rallies is not what america is about. Reporter trump then accused sanders supporters of starting the demonstrations. They were taunted, they were harassed by these other people, these other people, by the way, some represented bernie. Our communist friend. Sanders fired back in an interview with reverend al sharpton airing today. We have never, never once told anybody to do anything like that. The truth is, this guy really is a pathological liar. This comes as the democratic race is heating up. Sanders increasingly competitive in states like ohio, illinois and missouri after his surprise win in michigan. His call to reform job costing trade deals resonating in the rust belt. Instead of wages going up, theyre going down. Reporter on saturday clinton also called for stiffer trade laws but created a small dustup when she accused sanders of being absent during the 199os health care fight. I dont know where he was when i was trying to get health care. Reporter then a sanders aide tweeted this video from 1993, sabders standing behind the then first lady during one of her health care speeches. And im grateful that congressman sanders would join us today. Reporter the Clinton Campaign pushing back, arguing she was the one leading the battle for health care reform. The tense back and forth underscoring the very high stakes on tuesday. I promise you this, i will work my heart out for you. Reporter kate, the Clinton Campaign says even if secretary clinton loses some of these midwestern states, if she wins florida, and north carolina, she could expand her delegate lead on tuesday, still if senator sanders has a strong showing, this race could go all the way to the convention. Kate . All right. Kristen welker up in ohio. Kristen, thanks so much. Donald trump, with a commanding lead here in florida, in our new poll out today. Can any of his challengers turn the tide in these final two days before tuesdays primary . As we go to break, saturday night live poking fun at the recent protests at donald trump rallies and ben carsons endorsement of donald trump.
