I honestly did not. I heard the first shot and the second shot and i stood ther on. I was a little confused at the time because i didnt think there were gunshots then out of nowhere, i hear two, three, four, five and id see a bunch of people running out of macys and thats when i knew that shots were fired and, i mean, everybody went crazy, so, you know, i did what i could.

What kind of impact do you think this will have on your community . You know, i believe this is going to have a big impact because i mean were two small towns and, you know, this is our mall. This is our community and, you know, we like to feel safe in the community at least, you know, and secure and, you know, this happening is kind of you know, it shocked everybody. It shocked me as well but its just something that the community is going to have to get through and, you know, in time we will but its a sad day. Indeed and were sending our best to you and to everybody in that community. Thank you again for your time this morning and for doing what you could overnight when the worst imaginable took place. Armondo patino, thank you. Thank you. And we will continue to moving now to the reports of new evidence in the Fatal Police Shooting of a man in charlotte, charlotte, north carolina. All of this comes as his family releases this harrowing video showing the final moments of keith lamont scotts life. Abcs eva pilgrim is in charlotte this morning for us where there were more protests overnight. Eva, good morning to you. Reporter good morning, paula. Damage from prior protests has the city of charlotte on guard this morning. But we have seen now a second night of peace this as were learning more about the Fatal Shooting that sparked this outrage. This morning investigators reportedly saying new evidence in the shooting death of keith scott. Sources telling charlotte abc affiliate wsoc that testing of the weapon cops say was found at the scene allegedly shows a match for keith scotts fingerprints, dna and blood. Dont shoot him. Dont shoot him. He has no weapon. Reporter this coming as keiths wife shows her begging Charlotte Police not to shoot her husband. Drop the gun. Keith, dont do it. Drop the gun. Keith, get out the car. Keith, keith, dont you do it. Dont you do it. Keith. Keith. Keith. Dont you do it. Did you shoot him . Did you shoot him . Scotts wife in disbelief he et behr be not im not going to coming near you. Im going to record though. He better be alive. Reporter for days protesters and scotts family have called on the police to release officer body cam and dash cam of the shooting. Charts police chief arguing the police video doesnt paint a full picture and wont release it until more questions are answered. If i were to put it out indisdiscriminate nationally and it doesnt give you good context, it can inflame the reporter the family who has seen the police video says its not clear what was in keith scotts hand but the Police Department says scott was armed and that this image captured after the shooting shows the gun they recovered. When you look at the picture they released its hard to tell what it is. It could be a gun. But its not clear. Reporter from the other angle this video shows what may be that same object far from the body raising more questions than it answers. The state now taking over the investigation. As far as that police video, the state says because cmpd has the original copy of that video they have the Legal Authority to release it. The state telling you city leaders are actively discussing the release of that video. Paula. All right, thank you so much, eva. We want to bring in sunny hostin who is also in charlotte for us this morning. Sunny, good morning. We want to talk about that report. According to our abc affiliate quoting a source, they say the weapon found by cops at the scene allegedly had keith scotts blood, his fingerprints, his dna but it seems like bits and pieces of information are coming to light. Does it confuse the situation . I think so. These investigations, paula, are very fluid and we are in the early days of the investigation here and so any conclusions drawn upon alleged leak information would be premature and it certainly does compromise the investigation. I important to note is that the family has requested an independent investigator. An independent investigation. That is now considered the best practice when it comes to these Police Involved shootings and we do now know that the state bureau of investigation is now handling this case and so, again, investigation is very, very fluid and at its earliest stages. We saw that video that keith scotts wife shot, the family has also seen the police video. Calls to release it to the public. The chief didnt want to inflame the situation. Is that the right call . I dont think its the right call and i can tell you that last night i was in downtown charlotte. I was speaking to a lot of the protesters. There were chants there was chanting release the tapes and every Single Person that i spoke to felt that the Police Department was being less than transparent. Its leading to a distrust of best practices has been to be much more transparent with the community and i think that would go a long way in terms of giving this broken and fractured community a better, better sense of justice here. Cries for transparency this morning in charlotte. Sunny, thank you. Dan. We move on to the race for president and tminus 2 1 2 days until what promises to be an epic night in american politics. Clinton versus trump in their first debate. Expected. Both candidates are busy preparing this morning but in very different ways and abcs mary bruce is in our Washington Bureau with more. Reporter with that debate around the corner the campaigns are studying each other weaknesses, setting expectations and already playing head games. This morning, two very different candidates preparing to face off in two very different ways. In one corner hillary clinton, the veteran debater readying for yet taking the traditional route shes hunkering down with briefing books holding mock debates and looking to get under trumps skin. Starting with the front row. Im out. Im out. Reporter her campaign giving a coveted ticket to trumps nemesis, fellow brash billionaire mark cuban. Lets put it this way if he came on shark tank i wouldntmake the investment. Reporter this will be trumps 12th debate but his first oneonone and when it overdoing it. Ive seen prepare so much that they get up there and they get lockjaw, they cant speak. Reporter trump is bringing in backup. Rudy giuliani leading fridays strategy session. Lets have the American People see a person actually be themselves. Reporter so no mock debates, just rapidfire questioning and careful review of clintons past performances. And now trump is getting a surprise boost from a former rival. Lying ted cruz. Lying te he puts it down and he lies. Reporter just two months ago ted cruz refused to endorse trump at the convention. Vote your conscience, vote for candidates up and down the ticket who you trust to defend our freedom. Reporter now an aboutface saying he will vote for trump speaking with our houston station ktrk. I have forgiven him this. Is not personal. Its not about our family. Back now with mary. I guess the question is what is behind cruzs change of heart . Why now and who benefits more here, cruz or trump . This is a risky gamble for ted cruz. No question. After taking a hard personal and principled stance against trump cruzs change of heart is shocking but may be politically advantageous. Cruz is facing a possible primary challenge and the rnc said republicans who dont back trump could be made to pay for it down the road. Dan. That is but many of cruzs supporters are unhappy this morning. Mary bruce, thank you very much. Want to bring in abc news political analyst matthew dowd joining us from austin, texas, this morning. Hi, matthew. Apparently hell froze over and ted cruz endorsed donald trump. Is it really going to party in the end . Good morning. I actually think it doesnt help donald trump at all. Its not going to contribute anything in the course of this campaign but i actually think it hurts ted cruz in his future ambition, one to get reelected trump loses run for president in 2020. It makes him look cravenly opportunistic and unprincipled and doesnt help ted. Lets loop back to the debate on monday night. Style is tick differences between these two candidates could hardly be more stark. The super studious clinton and seat of the pants up until now trump. How is this likely to play out on stage . I think what will play out weaknesses node to go on the other side. Hillary clinton cerebral but doesnt have a gut connection. She has to become more visceral i think in the course of that debate. I think donald trump very visceral has to be has to look more cerebral and have more of a head connection. They each have to go to the other sides strength and adapt in that hour and a half. The first time he has debated oneonone. Its been one versus 17 but how consequential do you think this outcome. This is the most important moment of the entire Campaign Starting at the nomination process until election day. Without a doubt it will have more of an effect than anything else in this race in the time that we have left in this. It will move voters. How permanent that is, we dont know. Weve seen it happen in the past but this thing will be watched by as many people as watched the super bowl. As we said, an epic night i matthew, we know youll be right there for all of it. Thanks for being with us this morning. A reminder you can watch that right here on monday night, abc news chief anchor George Stephanopoulos will be leading our coverage and joined by martha raddatz, david muir, jon karl, tom llamas, cecilia vega, byron pitts and matthew dowd who you saw as well as Cokie Roberts and all starts at 9 00 eastern.

The president rejecting the measure that would allow survivor and the families of 9 11 victims to sue the government of saudi arabia saying hes concerned that its going to leave the u. S. Open to similar lawsuits, congress is expected to override that president ial veto. Authorizes say they suspect Russian Hackers were behind that massive attack that exposed 500 million personal yahoo accounts and posted a scan of Michelle Obama yahoo is being sued over this attack. The fbi revealing that new york city terror suspect Ahmad Khan Rahami took the train from his jersey home to manhattan with those bombs that he later placed on the city streets. New video shows a passerby kicking the can that contained that loaded Pressure Cooker which thankfully never went off. An incredible piece of video. Ron likes to end with some crazy animal. Story.

Lets take you to iowa where they have some issues with flooding and still rising are the rivers, this is out of manchester, iowa. State of emergency declared by the governor there for 13 counties. Waterloo is getting it, cedar rapids, also going to have some issues here as we go through Vernon County in wisconsin, look at these aerial shots for devastating flooding there in the southern part of the state. The rivers in wisconsin are at least cresting now and should be receding. That doesnt do much for the damage but the rivers in iowa are still rising especially the cedar river which got to get through cedar rapids. Wont crest until monday and that water will get down into the mississippi. An ongoing issue and another front coming through. Wont bring a whole lot of rain thankfully to the northern part but bigtime fire weather watch for the west.

To celebrate the opening of the newest africanamerican museum. President obama hosting a big reception at the white house on the eve of the opening. Abcs robin robs got an exclusive interview with the president as well as the first lady ahead of the museums opening. Almighty, its here at last. And its beautiful. Decades in the making. A museum that chronicles both the tragedies and triumphs of american history. The 19th museum of the smithsonian campus exhibits over 3500 artifacts to honor the africanamerican journey. I know that you both have had a chance with your family to tour here. What were your First Impression, mr. President. The First Impression you are not just narrative of slavery and the Civil Rights Movement but youre also reminded of how much the africanamerican experience has contributed to American Culture and American Music and sports and film. This will end up being a museum for all americans. We remember, mrs. Obama, at the Democratic National up every morning in a house built by slaves. And i watch my daughters, two beautiful intelligent black young women playing with their dogs on the white house lawn. One of the many things that struck me was that so much of what has happened and is represented in this museum has happened in our lifetime. You know, when you think about the fact that my great greatgrandfather was a slave and today i live in the w house, that progress is huge and its fast. To know that there are young people who now believe because of both of you that anything is possible, how does it make you feel in your heart and your head . I do think my presidency has sent a message to kids across the board. The sense that the human spirit can transform even the worst of circumstances into something opening day but, you know, this was an idea suggested in 1915 by black civil war vets. It took legislation by congress in 2003 to get the ball going and here we are today. Robin said here at last. Coming up on gma on this saturday morning. Look at this. Caught on camera. Police pepper spraying a teenage girl. Well hear from her afte
