Police say they were trying to serve a warrant tuesday to a different man at this apartment complex when they encountered scott, who had a gun. They were instructing the subject, once he got out of the vehicle to drop the weapon. Did you see any gun on him . I did not, no gun, it was a book. This woman says she watched the shooting from her secondfloor balcony and took a cell phone video of the aftermath. She said scott was reading a book waiting for his sons school bus and was disabled because of a previous head injury.

New Surveillance Video obtained by nbc news is said to show terror suspect ahmad rahami saturday evening. Moments after Officials Say the first explosive he planted in new york city went off. In the video rahami drags a suitcase, stopping to fidle with it before continuing on. Also seen, two unidentified men who allegedly took the bag, but left behind an explosive device that had been inside. Investigators now want to know who they are. They are witnesses, there are no criminal charges, theyre not in any jeopardy of being arrested. Fuelled by hate, ahmad rahami planned his jihad for months, this according to this criminal complaint discussed on capitol hill where a congressman held up a picture of what he said is rahamis bloody notebook. Its clear from this journal that mr. Rahami was receiving inspiration from the isis spokesman. Written inside said the fbi dwod willing the sounds of the bombs will be heard in the street. Gunshots to your police, death to your oppression. The chilling look at the suspect, who is said to have watched jihadi videos paints the picture of a calculating violent extremist. After years of trips to afghanistan and pakistan, in june the fbi says rahami ordered materials on ebay using his own name. To build bombs. Today his family is under scrutiny. Investigators believe a relative took video of rahami lighting incendiary material in a back yard. Today, a burn mark clearly visible. One of rahamis brothers in pakistan was detained. And is now in the custody of u. S. Authorities. The suspects wife, said to be cooperating, was interrogated in the united arab emirates. His mother is believed to be in turkey.

Again, she is not a suspect, but the case is wide open. Savannah, its unclear if shell return here to the family home. So many questions tonight. Miguel almaguer, thank you. We move to president ial politics. Our brand new nbc news wall street journal poll, it shows in a fourway matchup, Hillary Clinton leads donald trump by six points nationally, 43 to 37 .

Boxing promotor don king is hyping donald trump in cleveland as the chosen warrior for blacks and women. He is the leader that will lead us to the promised land. Every white woman should cast their vote for donald trump. King letting slip a racial epithet while giving a rambling introduction to trump, who is himself fighting off accusations of racism. If youre dancing and sliding a negro. Things couldnt be worse in africanamerican communities. Claim civil rights pioneer john lewis disputed. If he fails to believe that things have changed. I invite him to come and walk in my shoes. Right now trump is polling to 7 among Hillary Clintons 81 among africanamericans. Both candidates speaking out about the deadly Police Shootings, of black men in charlotte and tulsa. Trump questioning the female tulsa officer who killed the unarmed motorist. Did she get scared . Was she choking . What happened . Maybe people like that, people that choke, people that do that, maybe they cant be doing what theyre doing. Clinton demanding change. Look i know i dont have all the answers. I dont know anyone who does. But this is certain too many people have lost their lives. Who shouldnt have. Meanwhile, trump is still fighting off inquiries into his own foundation. The campaign saying a Washington Post report uncovering four new allegations of selfdealing, worth 250,000, is peppered with inaccuracies and omissions from a biased reporter. But the campaign offered no specific examples of what was inaccurate. Public records show he used Foundation Money to settle legal disputes and buy items he kept. Including a 10,000 portrait of trump which appears to be hanging at his doral golf resort, according to a photo from trip adviser. On capitol hill, the irs commissioner wouldnt comment on the foundation. But did say this no taxexempt organization can benefit, use its funds to benefit any in effect insider.

Mylan pharmaceuticals accused of driving up the price of epipens from under 100, to more than 600 in ten years. They raise the prices. The reason being, i believe, to get filthy rich at the expense of our constituents. Weve worked diligently and enhanced to make epipen more available. New allegations, u. S. A. Today reporting that Heather Breschs mother, the wife of senator joe manchin leaded the lobby effort to get epipens in all schools nationwide. Gail manchin was the head of the state boards of education. She tells nbc news my only concern and motivation was and always will be how we can protect as many children as possible.
