This is msnbc live at 8 00 eastern time. Three major stories. Coup attempt in turkey, noois terror attack and donald trump introduces his running mate. Msnbc headquarters in new york. We begin with breaking news out of turkey. A much calmer after the president declared an attempted military coup failed. Overnight explosions, gunbattles and air fire that killed 161 350e people. It all started when unidentified faction rolled into the streets claiming to take control. It was quashed by those loyal to the government. Tens of thousands of protesters, nearly 3,000 people were detained. Lucy cavanaugh with development from the bureau. Lucy, update us on the situation now. Reporter good morning. Ive been speaking to people on the ground saying the streets right now are early deserted. Almost like nothing happened. Minimal security presence, nothing like the mayhem overnight with tanks, soldiers, demonstrators in the streets. I was phone with friends of mine overnight and we kept hearing the sign of gunfire, deafening roar of military jets drowning out our conversations. Mosques blasting messages calling on supporters of president erdogan to take to the streets to defend gebs the coup attempt. We saw, of course, incredible footage of erdogan addressing the media on face time, something we havent seen in history. The president back in control, Prime Minister vowing those responsible for this coup will, quote, pay a heavy price for their treason. We know president erdogan spent the night at ataturk airport. He flew there from a turkish resort town saturday. He hid out, were hearing, inside the vip lounge. He left about two hours ago, destination unknown. That airport now reopened but many flights not all flights resumed. Many passengers stranded. U. S. Embassy warning americans security has significantly diminished at the airport instructing employees not to go in and out of ataturk airport. Talking about surprise. Certainly United States didnt know about it, knowing how fast and quick this developed with the president. Not even there. Were there any signs at all this was going to take place . No. I mean, people i spoke to in turkey, analysts i spoke to were stunned, terrified. Nobody saw this coming. Turkey is obviously no stranger to coups. Military toppled four civilian governments in six decades but erdogan seen as having brought the military under his control. His appointed senior commanders loyal to him, purged higher ranks he thought were a threat. We dont know the full scale of the coup, although we did see a statement from the military last night saying they were acting, they claimed, to restore democracy and human rights. Mr. Erdogan who has been in power democratically elected. He has been accused of taking on an authoritarian streak, subverting judiciary, jailing critics, shutting down newspapers and also dogged by corruption allegations. A very divisive figure reviled by his opponents and very much loved by his supporters. Of course the danger here is even though this coup has been detained, you have a divided public. Erdogan hours ago sending sms for people to take to the streets, turkey, frances, as you know key nato ally in the fight hosted 2,000 american soldiers. This will be critical for stability not just in turkey but the region. This the United States also weighing in on their support of the public. Lucy kafinov from our london bureau. Thank you very much. I want to bring you Jim Miklaszewski from the white house, the reaction to the coup attempt and support given publicly. Reporter the white house was very quick to react when word first came out there was a coup attempt under way there in turkey. Secretary of state john kerry was meeting with his russian counterparts in moscow and all of them were taken by total surprise. But the administration, despite all the problems that they have had with erdogan, despite problems with the people, corruption and the like, the white house and state department were very quick to react and issue statements of report as requested by turkish officials. There was one call placed by a frantic turkish official pleading with the administration to please issue a statement of support on behalf of erdogan. The president and john kerry, the secretary of state, did issue statements proclaiming their support for the, quote, democratically elected government, unquote, of turkey. You know, the democratically elected part was far more important to this administration at this point than any of the charges and accusations against erdogan and his government. Talk about the United States with military forces on the ground there in turkey, air base in Southern Turkey from where air attacks against isis have been launched and the measures they took while this coup attempt was happening and how that may complicate a relationship between two countries and our placement of forces there. Well, intriguing or interestingly enough, just before i came out here for this live shot, i got a call from a u. S. Official who said that for the second time in 24 hours, the Turkish Military has, again, suspended all combat operations, u. S. And coalition combat operations out of the air base, critical air base in southeastern turkey to launch strikes gebs isis in both syria and in iraq. The officials who we talked to this morning, moments ago, could not really explain what this suspension was for. But during the coup itself, those flights were suspended for only 25 minutes before the base commander lifted the suspension and those flights resumed routinely overnight according to the u. S. Officials. Were keeping track of that situation there to figure out what the latest problem or issue may be, frances. A heightened level of security there. Thank you so much, Jim Miklaszewski for us. Outside the white house. Appreciate it. Reporter you bet. Turb to president ial politics, reaction from mike pence tweeting for the First Time Since donald trump announced he chose him for his running mate. Issues they disagreed on in the past like banning muslims. Im very supportive of Donald Trumps call to temporarily suspend immigration from countries where terrorist influence and impact represents a threat to the United States. I have rejected throughout my career amnesty, but i believe we need to focus first and foremost, as donald trump has done with such force and passion on border integrity, building a law, internal enforcement. Later this morning trump will formally introduce governor pence at a News Conference in new york city. Meanwhile on democrat side Hillary Clinton has met with three potential running mates housing secretary Julian Castro be, also senator Elizabeth Warren and colorado governor john hickenlooper, whose name had not been previously floated. I want to bring in hallie jackson. The first joint appearance trump and pence in manhattan. What can we expect from that . Do you expect at all for them to address this rollout and how it came about, this announcement . The indecision or apparently the tla in this dramatics of wild ride the last 48 hours, we will see if either one of them addresses it. What i do expect from the event in manhattan is an introduction of who governor mike pence actually is. Hes a name that may be familiar to people in indiana. Hes familiar to those in tea party circles but the vast majority of americans are waking up over the last few days. Hey, mike pence, Donald Trumps new running mate, whats it about. You address the introduction, pence who did not endorse donald trump in the primary, a ted cruz backer prior to his states voting in the primary. He disagree on the muslim ban. What we have seen over the last 24 hours pence has done a public interview, a softening of the position on both topic, seeming renegotiating, for example, tpp, something he differed with triumph. Here is why pence says he backs trump and decided to join the ticket. Listen. Donald trump understands the anxiety and aspiration of the American People like no leader since reagan. Hes given voice to that. People have rallied around him and i believe will continue to rally around him. I expect next week at our convention youre going to see our party and leaders in our party rally ash this good man who will ab great president of the United States. So donald trump himself, has not addressed political rollout that was mishandled. When you do Something Like this, this is the biggest decision of the campaign for donald trump so far, one of the biggest decisions Hillary Clinton will make when she picks her Vice President and you dont want to mess it up. What youll see today donald trump and mike pence head out to the campaign trail together for the first time. Interesting to hear what they say and how they share the stage together, the chemistry, how they interact together. Thank you. So which candidate offers americans a better life . Thats an issue addressed in a poll. 36 say they would benefit more if Hillary Clinton wins the white house. 29 think they would fare better with donald trump. I want to bring in matt, chairman of the Ohio Republican party. Matt, thank you for being with me here. Just before ohio and the republican primary you told national memo, connie schultz, donald trump can be, quote, a transformative figure for gop. Just use his powers for good, hed be unstoppable. Has he shown he can use those powers for good, as you said . Changed your mind at all . Certainly brought a lot of new people into the party and process, added a lot of excitement and generated a lot of additional enthusiasm for this year. Were excited about having him in cleveland for the convention. When it comes to that, using powers for good, is there an example where youve seen that happen, something tangible . Obviously i thought his statement he made after the tragedy in dallas was right on. We have said all along it needs to be the kind of campaign it takes to win a state of ohio. No republican that ever gotten to the white house without carrying ohio. Hes going to have to win ohio. We know what it takes to win here, know the kind of message to win here. Were looking forward on winning the state and getting to the white house. Do you think his chances increased with mike pence as his running mate . Yeah. I think hes brought a conservative message, a conservative record of accomplishment as the governor of indiana, where hes created jobs and been an effective administrator. So he will help us and im looking forward to hearing him when he gets to cleveland next week. Looking ahead of down ballot races latest nbc poll, ohio seat, that is tied. Is that at least part of a thanks to trump . What kind of impact do you think it will have on those down ballot races. Last poll had rod portman up 5 points, ted strickland. I think that race trending in the right direction. Donald trumps appeal to democrats in the mahoney valley and coal country is going to help us bring new voters spot process. He already has done that. We have a million new registered republicans in ohio because of what happened in the primary. Even when john kasich won the primary and donald trump second he got more than Hillary Clinton did. Were in very good shape to win this year and im looking forward to helping us do that. Hillary clintons pick, brown her running mate, could florida be a problem for trump . I think hed hurt her ears. Well see what he decides to do, what she decides to do with the running mate. Well control things we can control and work hard. I think the fact ohioans think shes a liar. Shes proven time and again shes been dishonest about emails and all these different barely avoiding prosecution, thats not what americans are looking for in terms of a leader so well try to go in a different direction in the fall. Very quickly, sir, in the time we have left, john kasich, why is he not going to be at the convention in cleveland . Hell be in cleveland. Were having an event around the corner at rock hall. At the convention, sir . Hell be up in cleveland and be participating up here. So im looking forward to seeing him. Hes our great governor and we love him. He ran a Great Campaign and were proud of the effort he put forward. Im still proud hes our governor and im looking forward to seeing him next year. Chairman of the republican party, thank you for being with me. Thank you. In a moment the nice truck attack, a Prosecutor Says five people are now detained.

The development on the terrorist attack Chris Jansing live for us in east france. Chris. Reporter good morning. There is breaking news overnight. French prosecutors say there are five people they have detained overnight in connection with this investigation, what happened in nice, 84 people killed. One of the people they have detained and have been questioning, we knew about this, is his wife or exwife, estranged wife. Four of them are friends or acquaintances. We also know they have gone into two apartments he was in. One is where he lived with his family, including three children. The other where he went after reportedly he was told by his wife to get out. Hes known to authorities as a petty criminal, frankly but never anything that would lead them to believe Something Like this could happen. Hes certainly not on the radar of officials who look into terrorism, any officials here. Its caused a lot of problems, frankly, for president francois hollande, who has declared an official period of mourning, three days. That begins today. I think you can see from the pictures there the horror that unfolded when he drove that refrigerated truck down the streets, 282 injured. According to french officials, there are still 25 people who are in Critical Condition in the intensive care. Two of the people who were killed, americans, and at least one american a student at uc berkeley is missing. Frances. Chris, in this otherwise happy tourist seaside community, cant help but notice all the people behind you, they have been gathering there to pay your respects as well. What are they telling you . What can you hear from them . An extraordinary scene. Just to my right the waters, gorgeous blue waters of the mediterranean, some people when they were trying to get away from the truck jumped over what is a small raised area onto the beach. Some people even went into the water to try to escape the terror. But you see right behind me, and this street reopened very quickly, less than 24 hours, in that one center median, you can see thats where the memorial has been growing. I can tell you its grown significantly overnight. Just this morning on my way over here, i saw young man who had a huge spray of flowers he was bringing here. A couple of other women, one had white roses, another one a beautiful bouquet. Some walking away, one woman in tears. We see families coming here, many lighting candles, leaving notes. Its a shocking juxtaposition because just a couple blocks off here is a pedestrian area. There last night and again today the cafes are open, people are sitting outside. Its lunchtime here, people are sitting outside and eating and having a glass of wine. Not a lot of activity i will say that ive seen on the beach so far. This the height of the tourist season, one of the most beautiful cities along the French Riviera has really for a lot of people made them stop and pause. So far from the people ive talked to, i would say theres either an air of defiance, were not going to let what happened here stop us, have our vacation or at least acceptance. This is a part unfortunately of life in 2016, so onward we go. I have not spoken to anyone who has left here, frances, or anyone who was planning to leave because of what happened here . A lot of heavy hearts and something they know all too well in france. Nbcs Chris Jansing for us in east france. Chris, thank you. Back to politics and Vice President ial picks. How does mike pence help donald trump and how can he hurt him . Thats next. Very humble. What are you going to be speaking to mr. Trump about. Looking forward to meeting mr.
