First, the results of two races last night, marco rubio winning the primary in the District Of Columbia and after caucuses in wyoming, ted cruz picking up delegates in that state. Clashes at donald trump rallies on saturday. At one point the candidate had to be protected by secret Service Detail when a man tried to rush the stage. We have you covered on both sides. Lets start with nbcs hallie jackson. Good morning. Reporter good morning, craig. In bloomington, illinois, bracing for another day on the trail with donald trump, promising to push for arrests of those who interrupt his rallies, to, in his words, stop the craziness. Protesters, pepper sprayed during dueling 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 on stage to surround trump, blocking him from a man trying to rush him. This new video showing a different angle, the candidate clearly startled. I was ready for him, but its much easier if the cops do it. Reporter online and later on tanlg, trump making an inflammatory remark about the man. Then one of my people found his name and said it was probably isis or isisrelated. Law enforcement officials from two different federal agencies say they know of no isis connection, adding theres nothing to indicate any ties. Rising tension at rallies so unnerving to natalie hill, she and her husband discussed not going at all. We discussed if anything happened edge to the wall and get out. Reporter so you had an exit plan . Yes. Reporter his are questioning whether to support him if he win. Its getting harder every day. Everybody take a deep breath. Well see where it goes. Reporter ted cruz again is pledging to support the frontrunner if it comes to that. Donald trump, as president , i believe, would be a disaster but i think Hillary Clinton would be an even worse disaster. Reporter now marco rubio is putting some of the blame for whats happening at some of the rallies on president obama, telling the Washington Post theres, quote no, doubt the president has contributed to the divisiveness. How might all of this affect voters as we head into the key super tuesday primaries less than 48 hours away . Hallie jackson in bloomington, illinois, thank you. Democratic candidates are setting their sights on donald trump. The candidates are locked in an increasingly tight race on the democratic side. Critical state, as hallie just mentioned, set to vote on tuesday. Chr Kristen Welker is in cleveland this morning with with more on all of that. Good morning, kristen. Reporter good morning to you, erica. Campaigning here in critical ohio today. But on saturday, those violent protests loomed large. The rivalry between Hillary Clinton and Bernie Sanders is escalating. But 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 for starting the demonstration. They were taunted, harassed by these other people. By the way, some represented bernie, our communist friend. Reporter 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. Reporter 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 jobcosting trade deals resonating in the rust belt. Instead of wages going up, theyre going down. Reporter saturday, clinton also called for stiffer trade laws, but create aid small dustup when she accused sanders of being absent during the 1990s health care fight. I dont know where he was when i was trying to get health care in 93 and 94. Then a sanders aide tweet this had video from 1993, sanders standing behind the then first lady during one of her health care speech. Im grateful senator sanders would join us today. Reporter 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 tuesday. I promise you this. I will work my heart out for you. Reporter the Clinton Campaign says even if secretary of state clinton loses some of these mid western states, florida and north carolina, she could expand her delegate lead tuesday. Still a senator sanders has a strong showing, this race could go all the way to the convention. Erica . Kristen welker for us this morning. Thank you. Chuck todd is nbcs political director and moderator of meet the press. Good morning to you, sir. Good morning, craig. I watched the rally from beginning to end yesterday and i have to be honest with you. It feels like a certain darkness has befallen the trump campaign, chaos spilling into the streets, protests, pepper spray. Is there a chance that these images, that these scenes were seeing play out over the past few days, that theyre helping to rally his supporters . Short term gain, long term pain, craig, i think, for the party. It is possible it helps him. I think weve seen this before. When controversy befalls trump, it stiffens the spine of his supporters. They dig in. Sort of the more trump gets attacked. Look, i think thats why trump has hesitated, perhaps, to sit here and somehow take responsibility, blame his own supporters. He doesnt want to do that. I think he doesnt believe they deserve the blame. So but it does feel like weve entered a new phase. Again, i dont know if it has an impact on tuesday, but it is having an impact on whether donald trump can unite the republican party. And i think he took a couple of steps way back in his ability to do that, after on thursday night at that debate, looking like he was on his way to doing it. You mentioned stepping back from that, uniting of the party. We heard very clearly from marco rubio yesterday, he was wavering on his support. Same thing from john kasich. How does that all play out . In the end can they not support donald trump if hes the nominee . Theyre in a catch 22, the two of them, in particular. Theyve been so critical. Marco rubio said hes a con artist. So how do you somehow how do you somehow be able to say oh, i can support a con artist for president . So ive wondered the language both, frankly, kasich and rubio have used to criticize trump. By supporting him, it looks more double talkish than if they dont support him at this point. John kasichs folkses have said if he does not went ohio, he gets out. Its hard to see how marco rubio stays in, if he doesnt win in florida. What does a threeperson look like . How does a threeman race change the dynamic . Especially if its kasich and cruz here, i think it depends on you could see a couple of things happen. Number one, it means that trump, if he wins florida, but loses ohio, it means that trump will be the guy with the most delegates going into the convention. But hes probably going to be short of the majority he needs. And i think what youll see over the next few months is cruz and kasich will sort of divide and conquer. If they think kasich is a stronger antitrump candidate than cruz, cruz people will focus somewhere else, vice versa. I dont think theyre quite coordinating yet, but i wouldnt be surprised if you see that coordination as soon as two days from now, if kasich does win ohio. Cruz target arizona, kasich target utah and the two of them not get in each others way. Thats how a three person race could look, because it would be all about denying trump. Chuck todd, thank you so much. Well see more on meet the press when donald trump, john kasich and ted cruz join chuck on meet the press this morning. At least six people have been killed in part to the more than two feet of rain that fell on that area. More Severe Weather possibly on the way today.

He says he blacked out while driving drunk. The man he allegedly hit, fourtime champion jeff king, making the thousandmile trek through the alaskan wilderness, said it felt like Something Else entirely. It did not seem like an accident. It seemed like an act of bravado. Reporter king says the snowmobile slammed him from behind, narrowly missing him, but striking and killing his 3yearold pup, nash, and severely injuring crosby and banjo. One of my dogs was killed pretty much on the spot. And a couple of others, i gave first aid to the best i could and loaded in my sled. Thank you, guys. Reporter ally zerkel, racing just ahead of king, feared for her life. He freaking tried to kill me. Reporter she said out of nowhere the snowmobile ran into her sled, injured one of her dogs and appeared moments later, reving his engine. But he says he was just coming back to help. I turned around because i was concerned and i just had so much adrenaline. Reporter after meeting with law enforcement, both teams and their remaining dogs are back on the trail, hoping to put this frightening incident behind them.
