2016. Nightly news begins right now. Announcer from nbc news World Headquarters in new york, this is nbc nightly news with lester holt. Good evening. A shooting rampage at a major Shopping Mall in munich, germany has left at least nine people dead and many wounded. Video of a pistol armed attacker captured on a cell phone camera as he opened fire outside a mall shopping complex. People running in terror and police running into the scene. Tonight officials are calling it a suspected act of terrorism. Nbcs Kelly Cobiella has late details. Reporter the moment of terror captured on camera. Cell phone video purportedly showing how the rampage began outside a mcdonalds, the man dressed in black pulls a gun and starts shooting. People on the streets running for cover. Within minutes, police flooded in, guns drawn. Parents grabbing their children, dashing for safety and rescuers trying to help the wounded. It began around 6 00 friday night at one of munichs most popular malls, shots fired at the mcdonalds, then witnesses say inside the mall. At one point, witnesses told police they saw three shooters. This video from a Duke University student in germany visiting family. Police are telling us dont go to that mall. We heard gunshots and people screaming and running away. So we were in shock for five or six seconds an didnt know what to do. Reporter tonight the urgent man hunt for the shooter or shooters. Germany was all right on high aall right. Just four days ago, this 17yearold Asylum Seeker pledged allegiance to isis then attacked five people on a train with an ax. Tonight police scouring the neighborhood afternoon the mall, and again a european city is on lockdown and on edge. We want to turn to our chief Foreign CorrespondentRichard Engel now, peoples minds in europe turn to isis, but theres some other people at work in germany. U. S. Officials in germany say that they are leaning toward an alternate theory at this stage, that this was the work of german extremists, a neonazi group. They believe that one of the gun men has been killed, a body that was found. But they are operating on the aasumpation that other gun men were involved. If this was the work of neonazis, it shows how much anger there is, how much hate tread there is in europe. In this case, perhaps it was isis, but its more likelihood it was reactionary reacting because of all the attacks. All right, Richard Engel, thank you. To president ial politics this evening, theres high drama surrounding Hillary ClintonsVice President ial pick. Were expecting it to come at any home, first via text message to her supporters, all signs pointing to tim kaine. Andrea mitchell has late details from florida. What can you tell us about this . Reporter Hillary Clinton is expected to make that announcement by text message to her supporters and were getting some indications about exactly whom shes going to pick. Hillary clinton could name her running mate at any time. I think after the last week, what we saw in cleveland, we better be ready to go win an election in november. Reporter and tonight, democratic sources telling nbc news the likely pick is virginia senator tim kaine. Earlier this afternoon, kaine in boston not answering questions. Have you spoken with hillary . Reporter a former mayor and governor from a Battle Ground state with Foreign Policy experience, fluent in spanish too. Hillary clinton hoping to make that choice. Kaine admitting he lacks sizzle. Theyre true, i am boring. But, you know, boring is the Fastest Growing demographic in the country. Reporter just last week, a tryout to see if they had chemistry, the campaign liking what they saw. What tim kaine said is really worth considering, do you want a youre fired or youre hired president . Do you want a trash talker or a Bridge Builder . I like that one a lot. Reporter but the pick would come with some risks, because of his support for trade agreements. And his past views on abortion. The other veep finalist, Iowa Governor tom vilsack and cory booker. She wants someone whos qualified to be in the white house, someone she would like to partner with for four years, those are pa pa pa paramount for her. Reporter clinton will appear with her new running mail for the first time tomorrow in miami. Meantime, donald trump unleashed a new tirade today, trying to settle old scores one day after he officially accepted the republican nomination in a lengthy speech that painted a dark and dangerous portrait of life in america, arguing that he is the person to fix it. But did the man who wrote the art of the deal seal the deal with the American Public . Heres nbcs katy tur. Reporter donald trump coming out of the convention, off message with an ax to grind. Todays real tirade came just hours after the campaigns attempted course correction. Last night featured ivanca trump.

Reporter where crime is rampant. Homicides last year increased by 17 in americas 50 largest cities. Reporter and immigrants are partly to blame.

Doesnt really jibe with the experience of most people. The liberals have a whole set of evidence that might be right. Reporter Christina Perez was on the fence. Last nights speech didnt change her mind. I dont think i would vote for candidate trump. Im not sure at all at this point. Reporter so what about the ratings . The final night of the convention when donald trump spoke drew about 32 million viewers, thats 6 million less than john mccain did in 2008. Lester . Katy tur in new york tonight. We want to bring in our political director, the moderator of meet the press chuck todd. All leading up to the convention with the question of unity. We were there last night, it looked like a pretty happy crowd. How would you assess it . This wasnt a unified party going in. Obviously its never going to be a fully unified party. But trump did unify the con vengeanconvention. And rank and file republicans, did do a lot, because to get some of them unified because i talked to many republicans who are relieved that he didnt take the bait last night, when there were a couple of moments when he could have, when the crowd sort of started to talk lock her up, and he refused to do that. Todays ted cruz moment may give some frustration to pull their hair out. But for the most part, he did get more republicans on board. And i wouldnt be surprised if you see him get a bump in the polls. Because remember, he entered this convention with less support than normal for a republican nominee. Hillary clinton by naming a running mate, does that steal back some of the spot light after the republicans big week . I think it will, and it was sort of a way to lead into your convention, in a way the intention of what donald trump wanted to do the week before the campaign. News events and their own issues made that stumble. The Clinton Campaign is intended to have a much smoother rollout than trump and use it as a way to brag about that. Thats their goal.
