Warned of possible riots if he doesnt get the nomination. Ben carson drove the point home. There is no question there would be a lot of turmoil if the establishment tries to thwart the will of the people. Recognizing that millions of new voters have come into the republican poll. Largely as a result of donald trump. And it is very unlikely that those people would maintain their enthusiasm if in fact some shenanigans resulted in someone else being the nominee. Cnns Phil Mattingly live in philadelphia with more on this. Hi phil. Hey carol. Well yesterday was supposed to be a day where things called down. Let the dust settle after another big super tuesday. Get the measure of the republican race. Instead it raised a lot of questions about the direction things are actually headed. And part of the reason is this. People who are trying within the party to stop donald trump are really all pointing to that convention as the opportunity to do so. A contested convention. So trump has some rationale and merit to his concerns what might happen there but obviously a lot of concern his supporters very passionate and showing up in spades in somewhat troubling moments in chicago. Officials now real concerns not just with the brushback but also with the tone of where this is headed over the next couple of months. After mr. Trump made his riots comment yesterday the Republican National committee tried to tamp down the strong words. Here is a bit of that exchange i had with shawn spicer. I assume hes speaking figuratively. I assume if we go to the convention, whoever gets 1237 delegates becomes the nominee. Plain and simple. Delegates are represent im sorry to interrupt but i dont think mr. Trump was speaking figuratively. I dont think he was. I think he was serious. Then you should ask him carol. Well i appreciate you trying to guess what he was saying. So sean spicer did not like my, you know, my interruption but you can see the rnc is showing little concern things could actually get ugly but what is the reality. Well behind closed doors republican officials were always concerned about the security of a convention. That is just the way things go every four years. But the direction of this campaign has obviously increased that probably tenfold. I think what the rnc and what sean is trying to do there is tamp things down a little bit. Maybe bring rational thought to the direction things are happening and look at this logically. There is a lot of time to play out and a mathematical possibility donald trump would reach the total before they get to cleveland. But behind the scenes if you look at the violence, at the profanity, if you look at the whole direction, Top Republican officials very concerned about where it could be headed and to stop donald trump on a to try convention floor. There is a very real recognition of the backlash and the concern that comes with it. Mattingly live from philadelphia. A dose of reality now. There has been vients at trump rallies and there is evidence that authorities are not handling it properly. Five sheriffs deputies have been demoted or suspended without pay because of this incident. All of those deputies put on probation for a year. The protesters flips off the crowd before being sucker punched by a man named john mcgraw. The deputies failed to arrest mcgraw after the punch. In fact they did not arrest him until the next day after mcgraw went on inside edition and told the country, quote, the next time see him, the protester, we might have to kill him. So against that backdrop, chaos of a different kind, some conservatives are actively trying to thwart voters wishes by defeating trump on a number of back door ways. The cruz camp is quietly plotting a the battle at the Republican Convention and conservative blogger Eric Erickson is fighting for a Third Party Candidate, calling trump a moral cretan and a gold plated sleaze. Im joined now by cnn political commentator and former Capitol Hill Communications director tara setmayer. And donald trump trumps surrogate scotty nel hughes. So scotty, is mr. Trump hinting of a riot . I guarantee mr. Trump wants no violence. All he wants is peace and he wants the laws to be applied and the rules to be applied. And i this i that is what you are going to see. I happen to agree with sean that it was a figure of peach and all were asking for and i think the Republican Party has a great opportunity right now in fact. There are republicans disenfranchised and angry and upset and they were there way going into the 2016 election and the Republican Party has the chance right now to restore and repair a lot of this lost faith people have in the political process and that this party really does represent the conservative base. And it represents a wide variety of views. But does it in a peaceful fashion. Ben carson seemed to think there would be chaos. Were the most admired democracy in the world. What do you think of cubans or venezuelans or egyptians when they see violence at our political rallies . [ inaudible ]. Familiar to them. But listen, what is going on here is really concerning for a lot of reasons. First of all, i dont think the American People or the conservatives over 50 to 60 of folks in the Republican Party who are not supporters of donald trump should be forced to have to fall in line with someone they vehemently disagree with in values. Im a conservative. My values as a conservative do not fall in line with what donald trump is doing. Not only idealogically but character and integrity wise. So someone like this whos supposed to be a leader. Supposed to be the next president of the United States is so irresponsible with his words and how he portrays things moving forward using words like oh, trying to pressure people. There could be riots and set things up and people like scotty who yesterday on this channel actually said she didnt have a problem with riots and then had to walk it back because wolf blitzer said wait a minute. You dont really mean riots and then had to do verbal gymnastics to explain it. It is irresponsible language thats gotten us into the situation were in now. And moving forward it is unfair for people to think that we need to just fall in line with someone like donald trump who does not line up with our values. Im a conservative first. And i think there are many people out there who do not feel as though it is fair to have this shoved down but i will say tara. And here is the thing. And scotty you can reply to this. The voters have spoken. Republican voters are voting for donald trump. You cant deny that. I know you are a conservative and you dont like donald trump but you are beaten right now. That is right now. The game isnt over. I when you play football you dont decide in the Fourth Quarter when you still have an entire quarter to play if the opponent is winning to say im walking off now because the game is over. That is not how it works. But just a little bit of history. In 1860 there was a contested convention and the front runner was governor seward of new york and it took four ballots and who won . Ab lraham lincoln who was in thd or fourth at the time. And there were delegates and voting and it was civil. Not like this. People need to understand that no one is stealing votes away from anybody else. This is the process and donald trump doesnt get to change the rules now because he happens to be winning now. It is not over. Martin luther king used the word riot himself. He said it was the language of unheard. So if you want to sit there. Dont bring dr. Martin luther king was all about peaceful protest. No no . It was about peaceful protest. But dr. King i love how tara is trying to throw it that were trying to be unpeaceful and yet there is no criticism of groups like the democracy spring that is incouraging the largest civil disa beans in history starting next week. Almost seems like the talk tara is giving sides with them over the majority of conservative evangelicals. We are supposed to be better than them. We are but your [ inaudible ]. Who double speak and say we dont riots but they are okay and we want peace and then you have donald trump making comments and saying hes going to pay legal fees of a guy who said he should kill a protester and sucker punched him. It is irresponsible. You dont criticize the words of your own party right now thats lost his own two election cycles. [ inaudible ]. Worked in the i dont know how you as the conservative with conservative values square with what donald trump is doing. Even on policy hes not a conservative. Dont sit there and double question my conservative values another. Ive been consistent throughout my entire life. Ive got stop it here. But perhaps this is a sign of the Republican Convention to come. Thanks potato of you. And were going to talk about that lol. Isis and its mass killings and brutality that have horrified other terror groups. Two senior officials will say kerry will officially layer those murders as genocide. Unanimously approved by the house but resisted by president obama could force the u. S. To deeper involvement in fighting isis. Cnns elise at the state department with more on this good morning. You see secretary kerry speaking right now about the crimes and atrocities committed by isis. The u. S. Also calls it daesh. That is the nickname for isis. And secretary kerry has determined officials tell me is and is speaking right now to the fact that the u. S. Has determined that the atrocities isis is committing against yazidis and christians, other ethic groups is considered a genocide. You know carol, the u. S. Intervened to rescue hundreds of yazidis trapped on that mountain top in late 2014. But now the u. S. Determining that not only against yazidis but other crimes, beheadings, crewsifications, rape also considered a tool of genocide do constitute such a war crime. And as you said this will definitely reach calls for the u. S. To get more militarily involved. Congress almost unanimously approved a resolution earlier this week calling these crimes genocide. The administration under intense pressure not just from congress but christian groups, activists and others to provide some protection for these ethnic groups, carol. All right. Elise live from the state department. Still do come, some republicans signaling they could be open to the president S Supreme Court pick. The latest on the intense battle next. Wfrom your cold flu.

Hes giving his opening remarks right now and he told lawmakers that this was a failure of government at all level, local state and federal and said it is not about finger pointing and he says there is not a day or night that goes by that this tragedy doesnt weigh on him. He says his goal today in this hearing listen to tell lawmakers what hes doing to prevent another tragedy like what happened in flint michigan over contamination of its water. Well keep you posted on this. Supreme Court NomineeMerrick Garland will be on capitol hill today too trying to meet with senators o over whats sure to be a testy nomination process if it ever gets started. Some have signalled they are open to meeting with Merrick Garland. One person is decidedly not. And that would be Mitch Mcconnell who penned an op ed urging floe senators to moved with other matters. Writing in part, lets not allow partisan fighting on one issue to prevent the senate from addressing other priorities such as our economy and national security. Instead lets focus on where we can agree. Manu raju is following the story for us. Reporter this plays out in a very contentious Election Year environment. Republicans are defending 24 senate seats compared to 10 for the democrats. Republican leadership is betting this is going play well for them in november by firing up the Republican Base and claiming they could be a firewall against a progressive justice and right knew number of vulnerable republicans seem to be siding with their leadership. Give the people a voice in filling this vacancy. Senate republicans declaring president obamas choice for Supreme Court dead on arrival. Widely recognized not only as one of americas sharpest legal minds but someone who brings to his work a spirit of decency, modesty, integrity, evenhandedness and excellence. Reporter the president touting Merrick Garland as a consensus nominee with more federal judicial experience than any other nominee in history, who worked on high profile cases like the Oklahoma City bombing and the unibomber as the long Time Justice Department lawyer and federal prosecutor. Put this off until after the next president is elected. Reporter but republicans argue it is about principle saying American Voters should first elect a new president before conferring a nominee. Clear he made this not with the intend of seeing the nominee confirmed but in order to politicize it for purposes of the election. Majority leader Mitch Mcconnell even calling garland to say he will not meet with him or get a confirmation hearing. That principle has no history, no precedent and is virtually impossible to defend. Senate democrats urging counterparts to do their job. Give president obamas nominee a meeting, a hearing and a vote. We hope the saner heads will prevail. Reporter but tough races standing firm. If i meet with him it may not be a good use of his time because im not going to change my position. For his part garland not emotional yesterday. Having been passed over twice for a seat on the high court. This is the greatest honor of my life. Other than lana agreeing to marry me 28 years ago. Now the theatrics will be on full display on capitol hill today. Judge garland meets with members. And this Afternoon Senate democrats will gather to demand action on this nominee. This foreshadows over the next two weeks. Democratic activists will be in the home states of a lot of vulnerable republican hoping they will start to cave. Really weve only seen two but thats about it. Still to come an epic battle for donald trump and Hillary Clinton. How nasty could it get . For all. You may be muddling through allergies.

It is the latest attack by trump on his potential democratic challenger. And it could be a preview of a battle to come. A battle that could be one for the ages.
