Things change, as they say, in a new york minute. And now donald trump is releasing or has decided after his campaign criticized a number of leaks regarding his decision. And now the presumptive nominee for the gop, making it official that governor mike pence is his running mate. Well have much more. And you see there, theres a News Conference scheduled for tomorrow at 11 00 a. M. Kelly odonnell standing by for us. Kelly, to catch our audience up, i think people certainly saw many of those political junkies, as we refer to them, saw yesterday donald trump was expected to come out of the hotel and make this big announcement regarding his running mate after the devastating attack in nice. The Campaign Said that they would put it off until an undetermined time. And now here we are, at 11 01 eastern time, the exact thing that was supposed to happen today has happened. The announcement. Reporter well, tamron, i think this is driven by some of the pressure that is on mike pence that you might not find with the other top contenders who were not up for reelection, as we have talked about indiana governor mike pence, has been running for a second term. And the deadline is noon today for him to withdraw from that office, because under indiana law, he is not eligible to appear on the ballot for a statewide and a federal office. And so, if he were to take that move without having been formally, publicly announced, that would be politically very dangerous. And really, it becomes unfair to mike pence if he is the choice of the candidate, at some point, he needed a little backing here, so that he could take steps back in indiana to signal to his constituents something about his own future. Because now, presuming he will withdraw, that is the expectation within the next hour, hes got to tell through that, indiana voters what his future will be. So for mike pence, much more complicated. And then you add to it the fact that he got on an airplane, traveled to new york, without this being public yet. And my reporting tells me that donald trump, who was in california for a planned set of fund raisers, was in his home, watching news coverage, and was not pleased to see early reports, hours ahead of when he thought there would be any sort of leak related to this decision. Irritated by the fact that was coming out. And i think that from my reporting, there was a sense that this had gotten away from trump himself, and from the campaign. He was not surrounded by family who are often his closest advisers, his oldest children. Not really staffed in a way that a presumptive nominee would be. He was just out doing fundraising business, planning to come back to new york and have this all move forward today, in advance of the convention. And thats why were here in cleveland. So for trump, he then had to wrestle this back, after sort of taking a breather, seizing on the moment with the tragedy in france to say im going to put this off. But then the sort of exigencies of today, politically, mike pence couldnt be hanging out there any longer. So they have made this announcement, they will defer a public display of the two men together until tomorrow. And this is so different than any kind of traditional Vice President ial rollout. It is normally a big rally, and arms in the air kind of moment. This has not gone that way. Perhaps no surprise, because its an unconventional year. But thats where were at at this point. Thank you very much. Lets bring in nbcs katy tur outside trump tower. You heard kelly owe do believe use the phrase we hear over and over when it comes to donald trump and his campaign. That its unconventional. Is it also disorganized and perhaps some behind the scenes disarray regarding how this is playing out, even with the vp selection . Reporter you know, that is the accusation. And it was certainly they have been they have been hearing claims of disorganization now for months. Actually, since they started this campaign. It reached a fever pitch a couple months ago when Corey Lewandowski was nearing his end at the campaign. And now its reached that way again. I can tell you that behind the scenes, there has been some federation about aides speaking in Donald Trumps mind out of turn, saying things that he doesnt necessarily agree with. Claiming that hes going to back away from certain positions. And then those aides coming and getting a dressing down from donald trump himself. Hes even said so publicly, soandso is often misquoted. Or soandso got that wrong. Im going talk to him. Hes done that publicly in News Conferences. So there is a level of disorganization within the campaign. And that is because this is an untraditional candidate, a nontraditional candidate, who has refused to do things the normal way. And hes actively refused to do them. Hes been very vocal about his belief that he doesnt need the same apparatus as everybody else needs. That hes able to drive a message on his own. Hes able to garner free media attention, which is true. On his own, without having to rely on the traditional ad campaign. And we have seen that even since the general election has started, he hasnt been making very many or any at all ad buys across the street. But i want to tell that you governor pence and donald trump do have quite a few differences, tamron. If you give me a second, im going to run through them. The muslim ban, governor pence called it offensive and unconstitutional. As for building a wall he says i think its absolutely essential we have Border Security and supported that through my career but dodged whether or not he thinks there should be a wall. Katie, ive got to interrupt you and take our audience to nice, where were getting an update from french prosecutor. Lets get the latest there. The action of the First Responders neutralized this individual and avoided other victims being hurt or killed. I would like to thank all the services of the state that were involved. The security force, the firemen, the First Responders, doctors and associations for helping victims. But also all the citizens, the city of nice, who have shown an exemplary sense of solidarity and of duty. I would also like to underline the mobilization. If the forensic teams of nice and all doctors and personnel, who have offered their assistance. So the identification of the victims could start as soon as possible. This process of identifying the victims is very necessary in order to have a certitude about the identity of all the victims. I would like the whole Prosecutors Office, the whole everybody in the prosecutors will participate in this waiting period, and will be involved in any assistance we can give. The interministerial assistance to victims was activated immediately following the attack, and it can be called at 0143175646. This unit is to provide individualized assistance to all victims and their families, whether its psychological help, simply listening, or other forms of social assistance. I would also like to indicate that a Public Communications office has been established. It can be reached at 0496722222. With regard to the investigation in close relation with the prosecutor of nice, john michele pat, who did the first steps in the investigation, called us this morning, activating the Anti Terrorist unit of the Prosecutors Office of paris. Four magistrates from my office went to nice this very night, and have been leading the investigations by the police, and the justice department. The investigation has also been given to the ministry of the interior for assassination, criminal organization in relation to a terrorist ban, attempt to assassinate a member of the public authorities in relation to criminal organizations in relation with terrorists. And the attempt to attempt to organize terrorist attacks. These are the first facts. The first data that we have been we have from the first witnesses. So on at 10 45, on the 14th of july, a man acting alone in a refrigerator truck, who rented the truck at duval who would have given it back today, went on the promenade in the neighborhood. He drove for two kilometers between number 11 and 147 of the promenade, and violently impacted very large crowd of spectators who were there for the traditional 14th of July Fireworks display. The terrorist shot three policemen at the hotel negresco. The Police Responded and pursued the truck, which unfortunately managed to keep going for 300 meters. The police managed to neutralize him with shot. The passenger found dead in the passenger seat. The cab of the truck only had a bicycle inside, and eight empty transportation pallets. In the cab of the truck was an automatic pistol, 75 millimeters, a charger, and explosive bullets and nonexplosive bullets of the same caliber. A second automatic pistol. Two copies of assault rifles, an m16. A hand grenade. A mobile phone, various documents that are still being investigated. We have also discovered also in the cab of the truck a map, a bank card in the name of Mohamed Lahouaiej bouhlel born 3 january 1985 in tunisia and a resident in nice. The fingerprints and other genetic material has confirmed his identification. He was a deliveryman of tunisia nationality, married and the father of children. His wife has been called in to the Police Department this morning. He had already been under Police Interference because of menaces, threats. He had been condemned the 24th of march, 2016, for 16 months of imprisonment for intentional violence committed in january of 2016. He had, however, his completely unknown to the information services, or in any national database, and was never part of any surveillance. The first Video Surveillance showed the truck used by the terrorist in the neighborhood in the east of nice, where it had been parked since the 13th of july. The truck was picked up on the 14th of july by Mohamed Lahouaiej bouhlel, who arrived alone, by bike. The bike which was found in the truck. He then went to the west side of the city. The truck then reappeared at 10 30 in the neighborhood and then headed toward the promenade. Searches were conducted at two addresses where various materials, computer material and mobile phones were taken, as well as several documents. These these findings are being investigated. These are the only elements that i can share with you. The investigation has just started, as i said. And in order to make the work of the investigators easier, in order to use the weapons and the materials and all the very bountiful data found in the Video Surveillance and in the telephones. We are researching the source of the weapons found by the criminal and we are trying to find out whether there are any accomplices. And were also trying to determine if there are any possible links between Mohamed Lahouaiej bouhlel with organized criminal bans that are islamic, the attack yesterday was not claimed by anybody to date. However, i must remind you that this type of action is very much within the framework of the permanent call for murder by terrorist organizations. They permanently call for in their various publications and videos. Thank you very much for your attention. And ill keep you updated with any developments in this investigation. Thank you very much. We received more details, as you heard there, on the investigation. The individual french Authorities Say carried out that heinous act. Right now what we to know, and lets talk about those who lost their lives. At least 84 confirmed killed. Ten of those children. And teenagers. The french prosecutor giving more information on Mohamed Lahouaiej bouhlel. He described him as a delivery man, a married father, who on july 14th, went to a facility and rented the refrigerator truck, according to the prosecutor, alone, traveling by bicycle. Around 10 45 p. M. , that is when this individual plowed through the spectators celebrating bastille day, in that rented truck. Again, the authorities there confirming they found several weapons, a map, a bank card they used to identify the suspect. He shot three policemen before they were able to ultimately take him out. And he was found behind the wheel of that refrigerateded truck. The identities of the People Killed in this act of terror, theyre coming in right now. What we do know is at least two of the victims were americans. That is according to the state department. We have a family spokesperson now who identified them as 51yearold Sean Copeland and his 11yearold son, brody. They were visiting nice like so many others around this time of year. Let me bring in msnbc contributor and daily beast news world editor, dickey. Those who remain in critical condition, christopher, were looking at some of the information on this mans background. He served, the prosecutor says, 16 months behind bars for a violent act. He didnt go into great detail. But one of the highlights here as far as the information. He was not on a database. He was not under surveillance. Reporter thats right, tamron. Frankly, that has them disturbed, the Counter Terror people here in france. Because they have seen in the past cases, although they fumbled the ball, and they didnt arrest or didnt cover closely enough the people in the Charlie Hebdo massacre and the brussels massacre. Those were at least people that were at some point on their radar. This guy was never on their radar. He was just a criminal with violent proclivities who had been in and out of jail. There was no indication that he had any kind of jihadist connection, as far as the Intelligence Services were concerned. And yet here hes killed 84 people, and wounded seriously scores more. Was he acting for isis . Was he acting on his own . Thats what theyre trying to figure out by going through his telephone and by looking at whatever documents he had in his apartment. In the truck. And also by interrogating his wife, the mother of his children. Christopher, this attack comes as the french president , francois hollande, was actually, as we understand, considering lifting this state of emergency that so many people have questioned whether it was still necessity point. But also mindful of the possibility of Something Like this happening. And here we are, again, discussing this and looking at the mass casualty, which includes children who were there with their parents, who were in the sights of this madman. Reporter tamron, it is hard to overstate the horror of what happened last night. Men, women, children out for a good time. Watching fireworks. You know what its like when youve got thousands of people watching fireworks in a beautiful locale. Think of the beautiful mal in washington, for instance. People are happy, about to go their own way, whether its to bars, restaurants, their homes. All of a sudden, this refrigerator truck comes barreling down the sidewalk, just above the sea and starts to take them out, zigzagging back and forth. I dont know if you can see behind me. But there is a dome back there, the hotel. Thats where this guy started shooting at the police. He shot three police back there, around the hotel. Before coming about another 200 meters toward us to that sort of modern hotel with the square columns. Thats a little bit closer. And thats where he finally was taken out. The truck has been there all day. You can see bullet holes all the way through the front of the all over the front of the wind screen. And he was found slumped, finally, in the passenger seat in the front of the truck. So it was a really bloody scene. Was this guy acting alone . Had he had any kind of training . Is this something he had planned for months or years, or is this something he planned almost on the spur of the moment . The day or two before he rented the truck . Probably not. Because the big question, if theyre looking at right now, is where the hell did he get those arms . I mean, this is not alabama or South Carolina or texas. You just cant go buy automatic pistols in any old store in town by showing your drivers license. You have to get them on the black market, and if youre going to work in the black market, youre going to be connected, especially in this town, with all kinds of shady people. And thats reporter whether terrorists, whatever. Christopher, thats the interesting point. I was there last year celebrating bastille in that very location where this took place. And when you look at the security and the climate of nice, and many ways, yes, paris has been on alert. I have read a number of opeds from parissans who say it could never be the same there because of the tension and fear. Thats not what people describe as the feeling in nice. How would you describe, at least from your estimation, how security was treated . How the possibility of Something Like this was treated in that part of france . Reporter well, look, tamron. Everybody is always solving the last terrorist attack. And the terrorists always come up with new approaches that somehow bypass everything that happened before. Terrorists successful terrorists, are very imaginative and creative. We should never forget that 9 11 was carried out with box cutters that turned passenger airplanes into flying bombs. That is an extraordinary thing. This is an environment where the police were looking for bombs, theyre looking for people with guns, theyre looking for all kinds of things. They werent looking for a refrigerator truck that would just blast through the barricades along the promenade and start to mow down civilians, innocent men, women, and many children. Christopher dickey, thank you so much. Let me bring in eamon mayhew dean regarding this familiar and family in tunisia. We know according to officials in france, he is a french resident or at least has french residency status, perhaps something equivalent to an American Green card, allowing him to live and work in france. But not necessarily a french citizen and national. That led french authorities to contact their counterparts in tunisia, the country of birth and origin. And we understand, according to tunisian sources, his
