Secretary clinton told me in an exclusive interview here in des moines today that there is nothing regarding the email investigation that should cause voters to have any concerns, the state department confirmed for the first time that some of the emails found on clintons personal email server from her days as secretary of state contained information so secret, it fell into the highest level of classification. Nbcs Andrea Mitchell has details. Reporter as Hillary Clinton was campaigning in iowa, the state department dropped the email bombshell. For the first time labeling 22 emails from her private server top secret. The highest level of classification as demanded by the intelligence agencies. None of this traffic was marked classified at the time it was sent. Just minutes earlier, lester had asked clinton about how the email investigation might affect her campaign. Anything could happen. Indictments could happen. Why shouldnt people, if they weigh the electability question, hanging over your head as you march forward. Because the facts have remained the same. There was never any information sent or received that was marked classified to me. For people who are watching this play out and know the republicans will come at you on this with an open investigation, shouldnt people have some concern . No, they shouldnt, lester. I just dont see it as anything that will in any way cause any voter to a voter with an open mind to have any concerns. Reporter Clintons Campaign called it a bureaucratic turf battle. These emails should be released to the public can view them. This is an example of overclassification run amok. Reporter jush tweeted Marco Rubio Rubio said. This is unacceptable. This is a disqualifier. Bernie Sanders Campaign says he stands by this. The American People are sick and tired of hearing about your damn emails. Thank you. Me too. Reporter the state department wont be releasing these emails now and may never, but this reignites the email issue just as the voters are about to have their say. Lester. All right, andrea. The timing of all this hardly ideal for the Clinton Campaign as she tries to break out of a dead heat here in iowa with Bernie Sanders over these next three days. In our wideranging conversation today, secretary clinton vowed she wouldnt go negative on sanders, but she is eager to point out their differences. Who has the achievable plans that can actually make a difference . Who can beat the republicans . These are the kinds of issues that i think as we go forward, people are going to say, hey, shes given me a specific set of ideas. Shes told me what its going to cost. Its not pie in the sky. It can actually deliver for my family, and i think thats what people are looking for. Is senator sanders speaking in pie in the sky terms . Well, i think now that his policies have come under closer press and others, hes having to answer some questions. And now Bernie Sanders is trying to place the scrutiny on clinton too. His new ad this week, not mentioning her by name but taking clear aim at her paid speeches to wall street banks. How does wall street get away with it . Millions in Campaign Contributions and speaking fees. The fact that youre in a virtual tie here, does that signal that this attack is gaining traction . I i dont think so. I dont think so. I think that, you know, im going to remain positive. And its a little disappointing that senator sanders is trying to go negative. Hes trying everything instead of trying to answer the legitimate questions that people are asking about how you fund a 15 trillion health provide free college for everybody, all the things hes being asked. Instead, you know, attention. That is a timeworn politician tactic. One of sanders sharpest jabs just on my opponent is not in iowa tonight. She is raising money from a philadelphia investment firm. [ crowd booing ] you went to philadelphia this week. Fundraiser with a Financial Firm as the backer. Was that a mistake . No. I mean i am proud to of support across the country. I did go. But did it play to his narrative about you . Well, only if you think his narrative is correct, which of course it isnt. Look, we both have stood up to wall street. I stood up before most people stood up back when i was a senator. We both have plans. Mine is more expansive, tougher, more effective, comprehensive. I want to ask you about a moment at the town hall. A young man, Bernie Sanders supporter, stood up and said, young people dont trust you. Ive heard from quite a few people my age that they think youre dishonest. When he said that, i winced, and i was wondering, youve obviously been in do you get your feelings hurt sometimes . Well, of course. Its not pleasant to hear that. I have led a very public life now for 25 years. Ive been subjected to all kinds of attacks, and in large measure because of what i stand for and what i fight for. But im going to answer questions regardless of where they come from or who poses them. What frustrates you the most about perceptions about you . You know, i dont even think about that anymore. I did for a long time. Youre human. It is painful. It can be hurtful. And its especially so for your family and your friends, who are just so hurt for you. But im i have no reason to think that im going to be given any break. I dont expect that. I expect i have to bring my best to this Campaign Like ive brought my best to everything ive done. And i think i have a people. Im just going to do what i think is right for the country and let the voters decide. Her chief opponent, senator sanders, told me on wednesday that with a good turnout, he will win in iowa. Secretary clinton says she doesnt make predictions and wont be doing so here. Meantime on the republican side, its shaping up to be a wild fight to the finish with donald trump declaring victory today for not showing up at the debate while his chief rival in iowa, ted cruz, tries to brush off headlines of a rough night on that stage. Nbcs Hallie Jackson has details. Reporter with 72 hours left, 24 stops by republicans in iowa today. But to frontrunner donald trump, the only numbers that matter here are his own polling. I think were going to do really well in iowa. Reporter trump so confident about iowa, hes in New Hampshire today, looking further north to hit ted cruz. Ted cruz is an anchor baby in canada. I like donald, and hes welcome to say reporter his campaign, meanwhile, serious about turning out caucus goers. Hi, this is rebecca. Im with team cruz. Reporter on the trail, cruz working to dismiss headlines about his rough night at the gop debate. My focus is on talking to the voters directly. Reporter cruz shrugging off criticism he missed an opportunity as trump flipped screens and split attention, hosting his own rally. I didnt want to be here. I have to be honest. But you have to stick up for your rights. When youre treated badly still mad at moderator megyn kelly. Lets address the elephant not in the room tonight. Trump, three miles from center stage, was the center of a attention early on. Everyone on this stage is stupid, fat and ugly. And ben youre a terrible surgeon. Now that weve gotten the donald trump portion out of the way reporter but its trump who, for now, looks smart for skipping out. The republican race has turned into a fierce battle for second place. So when ted cruz took without standing in Donald Trumps shadow, he really did not rise to the occasion. Reporter and while jeb bush run praise for seeming solid. This is not about our pedigree. This is about people who are really hurting. Reporter so did marco rubio, hoping for a strong third. Reading a supporters card to a fired up crowd. Friends dont let friends vote for trump. Reporter the Rubio Campaign is prepared for af long haul, betting someone will eventually emerge as the antitrump option. Who will that will be probably wont be clear until after the New Hampshire primary, where the establishment candidates are making their stand. And in a telling move, jeb bush, chris christie, and john kasich will not appear at events here in iowa the night of the caucuses, lester. Instead theyll be in the granite state. Hallie jackson, lets bring in our political director, the moderator of meet the press, chuck todd. Back to the clinton emails, its a scandal that wont go away. You know, thats unclear, but i will say this. Timing and innuendo are not her friend here. Just 72 hours before caucus night. Just when democrats are having this conversation about electability, i was at a sanders event today. Bernie sanders spends because he thinks that issue has been hurting him. Been making that issue. But then here comes this email issue. Here comes real questions. Theres uncertainty. You should see the words top secret, but we dont know much about it. Thats what frustrates the Clinton Campaign, lester, is they feel as if once all of it is out, it will be easy to explain. Right now, 72 hours before the caucus, it isnt. Ive talked to plenty of democrats that are undecided at events for clinton and sanders, who say to me, you know, one of the hesitations on clinton is this stuff thats always around her. Well, emails is part of that stuff, and frankly right now, it looks like a bit of a mess for the Clinton Campaign to explain. They can explain it away, but the timing is rough. All right. Chuck, thanks. Jampacked show from iowa including interviews with ted cruz, marco rubio, and Bernie Sanders sunday morning on meet the press. In california tonight, several new twists in that intense manhunt after a daring jail break. One of the three inmates has turned himself in.

Reminisce interest of Joyce Mitchell in the new york prison escape last year. There was some written correspondence. That would obviously go beyond the teacherstudent relationship inside custody that we could expect rsh the jail break reads like a hollywood thriller. The inmates cut through steel, snaked along plumbing ducts, passed pass razor wire. Its crazy. Reporter during the search, several gang members have been arrested. Theres been overnight raids. A hundred thousand dollars reward and a tonight an update from the Sheriffs Department here at the county jail. They say those two suspects, those two inmates are believed to be armed and dangerous.

Authorities say finicum did have a loaded semiautomatic handgun in that pocket. Scott reitz, an expert on use of force, analyzed the video. If youre an individual and the officers reasonably believe theres a high probability that youre armed, they do not have to wait to see a weapon being produced. Reporter but finicums family believes the shooting was not justified saying egg does not appear to be imposing any real threat or danger.
