Chase, a crash and the moment fbi agents opened fire. Nightly news begins right now. Announcer this is nbc nightly news with lester holt reporting tonight in des moines, iowa. Good evening. Three days from a critical vote here in iowa, and the Hillary Clinton camp finds itself back under the cloud of the email controversy. Minutes after 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. Emails found on clintons personal email server from her days as secretary of state contained information so secret they fell under 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. 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. Reporter just minutes earlier lester had asked clinton about how the email investigation might affect her campaign. Anything can happen. Indictments could happen. Why shouldnt people, as they weigh the electability question, worry about this 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 poem 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 in any way will cause any voter to a voter with an open mind, to have any concerns. Reporter Clintons Campaign called it a bureaucratic turf battle. Released so that the public can view them. This is an example of overclassification run amok. Reporter the republicans are pouncing. Jeb bush treated we need a president who can be trusted to keep our secrets secret. Obviously thats not Hillary Clinton and marco rube crow said this is unacceptable. Reporter Bernie SandersCampaign Says he stands by this. The american penal are stick damn emails. Thank you. Me, too, me, too. Reporter the state department wont be releasing those emails now and may never, but this reignites the email issue just as the voters are about to have their say. Lester . All right, and iia. 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 the 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. 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 sleep. s 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 is looking for. Reporter is senator sanders speaking in pie in the sky terms . Well, i think now that his policies have come under closer scrutiny from the press and others, hes having to answer some questions. Reporter 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. Reporter the fact that youre in a virtual tie here, does that signal that this attack is gaining traction . I dont think so. I dont think so. I think that, you know, im 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 care system, how you provide free college for everybody, all the things hes being asked. Instead, you know, hes trying to divert attention. That is a time worn politicians tactic. One of sanders sharpest jabs just on wednesday. My opponent is not in iowa tonight. She is raising money from a philadelphia investment firm. You went to philadelphia this week. You spoke at a fundraiser with a Financial Firm as the backer. Was that a mistake . No. I mean, i am proud to have such a broad base of support across the country. But it it d it play to his narrative about you . Only if you think his narrative is correct which, of course, it isnt. We both have stood up to wall street. Stood up back when i was a senator. We both haveexpansive, tougher, more effective, comprehensive according to people like paul krugman. I want to ask you about the town hall the other day. A young markings 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. And when he said that i winced, and i was wondering youve obviously been in tough battles, political battles. 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 because i i did for a long time. It is 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 track record of getting results for 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 win in iowa. Secretary clinton says she doesnt make predictions and wont be doing so here. 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 chive rival in iowa ted cruz tries to brush off headlines of a rough night on 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. Reporter just laughter is what you take away from it. I like donald and hes welcome to say whatever he likes. Reporter his campaign meanwhile serious about turning out caucus growers. This is rebecca with team cruz. Reporter on the trail cruz working to dismiss headlines debate. My focus is on talking to the voters directly. Reporter cruz shrugging off criticism that he missed an opportunity as trump split 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. Reporter still mad at moderator megyn kelly. Not iy the room tonight. Reporter trump three miles from center stage was the center of 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 that stage last night without standing in Donald Trumps shadow he really did not rise to the occasion. Reporter and while jeb bush won praise for seeming solid. This election is not about our pedigree. This is an election about people that are real hurting. Reporter so did marco rubio in iowa hoping for a strong third, but positioning to sneak into second today reading a supporters card to a fired up crowd. Dont let friends vote for trumpet so much wisdom, yeah. Reporter Rubio Campaign is prepared for a long haul betting someone will eventually emerge as the antitrump option, but 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, they will be in the granite state. All right. H ha llie jackson, thanks. Let bring in our political director and moderator of meet the press, chuck todd. Back to the clinton emails, a scandal that wont go away but does it resonate with voteers . 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 a lot of time on it because he thinks that issue has been hurting him. Hillary clinton has been making that issue, but then here comes this email issue. Here comes real questions. Theres uncertainty. You see the words top secret but we dont know much about it. Thats what frustrates the Clinton Campaign, lester. It will be easy to explain, but right now 72 hours befor the caucus it isnt, and ive talked to plenty of democrats who 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 here. Emails is part that have 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 timing is rough. All right, chuck. Thanks. Well be watching your 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.

Reporter after a week on the one of three dangerous inmates at the center of a mavis dragnet giving himself up.

Detectives say ravaghi developed a, quote, personal relationship with inmate hossein nayeri, reminiscent of the Joyce Mitchell prison escape last week, authorities the mastermind of the jail break. There was written correspondence. The teacherstudent relationship inside custody that we would expect. The jail break reads like a hole wood thriller. The inmates gut through steel and snaked along plumg ducts and rappelled six floors using bedsheets. Just like shaw shank redemption, its crazy. During the search several gang members have been arrested. Theres been overnight raids, a 200,000 reward and a plea for the publics help.
