Sreenivasan the federal government charged the suspect in the deadly new york attack, Sayfullo Saipov on two counts today provision of Material Support and resources to a designated foreign terrorist organization; and violence and destruction of motor vehicles. According to the federal complaint, saipov told authorities he started planning the attack about a year ago, rented a truck about a week before the attack to practice turns, and chose halloween because he thought there would be more civilians nearby. President trump today called saipov an enemy combatant, threatening to send him to guantanamo. The f. B. I. Says a second person is wanted for questioning, mukhammadzoir kadirov, a 32 yearold native of uzbekistan. Marcia biggs reports from manhattan on the mood in the city, and what we know now. I was sitting in class right there and i was nervous because this is so close to where it happened over there and i was looking out the window just in case. Reporter as new yorkers returned to school and work today, forensic investigators and Law Enforcement officials were piecing together a clearer picture of what led to the deadly truck attack on a new york city bike path yesterday. Police today said the alleged truck driver, Sayfullo Saipov, had been planning the attack for weeks. Saipov immigrated to the u. S. From uzbekistan in 2010 on a visa through the u. S. immigration lottery program. He worked as a commercial truck driver, and later as an uber driver. Police found multiple knives, a pellet gun, and a paintball gun in the vehicle, and say that the attack was likely isisinspired after saipov was radicalized on u. S. Soil. He appears to have followed almost exactly to a t the instructions that isis has put out in its social Media Channels before, how to carry out an attack. Reporter the victims of yesterdays attack are two americans, one belgian and five argentines, celebrating the 30th anniversary of their High School Graduation with a trip to new york. And boston. At 2 06 p. M. , saipov rented the truck from a home depot in passaic, new jersey and drove east towards manhattan, entering the city at 2 43 via the George Washington bridge and continuing southbound on the west side highway. At 3 04 p. M. , the truck then entered the hudson river bike path at the intersection of west and houston streets. It barreled down the path at a high speed for 16 blocks, hitting the eight victims before colliding with a school bus. Two adults and two children onboard were injured. Witnesses and police say saipov exited the vehicle waving a gun and yelling. 28yearold n. Y. P. D. Officer ryan nash, one of three Police Officers to first on the scene, then shot saipov in the abdomen, who was then taken into custody. Ryan stroker uses the path every day to take his daughter to school. So, picked her up at 3 00. We were stopped at pier 40, where we saw about six bikes completely destroyed. Luckily, just missed it. We have to get much tougher, we have to get much smarter and we have to get much less politically correct. Reporter speaking before a white house Cabinet Meeting today, mr. Trump called for the dissolution of the u. S. Immigration lottery visa program, and move to a merit based system. Diversity lottery sounds nice. Its not nice. Its not good. Its not good. It hasnt been good. Weve been against it. This man that came in or whatever you want to call him, brought in with him other people. And he was the point of contact, the primary point of contact for, and this is preliminarily, 23 people. Reporter fouziah and riyadh davids are visiting from south africa. Riyadh plans to run in the new York City Marathon this sunday. Did your heart sink when you found out he was muslim . Oh, absolutely. He doesnt represent what we stand for. Reporter mayor bill de blasio and new York Governor Andrew Cuomo warned against politicizing the matter. You play into the hands of the terrorist to the extent that you disrupt and frighten people in society. And the tone now should be of unity. Reporter and john miller, of the n. Y. P. D. s counterterrorism unit, cautioned against blaming a entire group of people for the attack. This is not about islam. Its not about the mosque that he went to. As the victims family begin to grap welwhat happened yesterday, and the city begins to get back to normal, it is important to remember there are still nine people in the hospital tonight, four with critical injuries, one with a do you mean amputation so people here still fighting for their lives tonight, hari. Sreenivasan marcia biggs in new york, thank you. Im joined by jeffrey ringle. He worked at the f. B. I. For more than two decades focussings he worked at the f. B. I. For more than two decades, focusing on counterterror investigations at the new York Field Office and abroad. He is now at the soufan group. What stage of the investigation are we at . Roit now, theyre still trying to discover more about the attacker, people he associated with, places he went basically building the background, building the story on him. Sreenivasan theres this overwhelming sense of despair and the idea the authorities have these people on the radar, but they cannot take any action against them. Why is that . Well, its a little frustrating, and i think people need to understand that Law Enforcement, the n. Y. P. D. , the joint Terrorism Task force, theyre having thousands of individuals who have been brought to their attention by people calling in suspicious activity or reporting something that they didnt like. The joint Terrorism Task force will do an investigation, and then determine if there needs to be more investigation, if the accusations have been validated. If not, the investigations are closed. But there are so many of these allegations coming in, that basically the f. B. I. Is overwhelmed. Joint Terrorism Task forces are overwhelmed. Sreenivasan we just learned from the most recent press conference, that they found hundreds of videos on his cell phone, images of isis videos, beheadings, and so forth. It seems the radicalization was happening here, that he didnt have to go to a terror training camp. Absolutely. And that is the problem thats going to face Law Enforcement and the Intel Community for decades to come. Social media has made it so easy for these hate mongerrers overseas to press their message to disillusioned individuals here in the United States and throughout the west that one of the trip wires we used to look for, the travel of subjects to terrorist areas, that no longer needs to be done. Theyre being radicalized over social media. Sreenivasan so how do you stop that . Do you stop all videos that are coming in and are questionable . Youtube seems paralyzed to try to figure out the answer to these things. Youre walking that fine line between constitutional rights, freedom of expression, you know, freedom of religion and criminality. And thats where and this is where im saying that the Law Enforcement, the joint Terrorism Task force, are overwhelmed because they may be following people, or they know about people who have these videos or have contact with suspicious email addresses or suspicious websites, but that in itself is not enough to arrest somebody. That is a piece of the investigation. The joint Terrorism Task force will try to do more investigation, put sources up against the subject, try to get that person to do something where wherethey can then be arrested. But until some violation of law happens, Law Enforcement, somewhat, have their hands tied. Sreenivasan this attack followed almost a textbook. I think there was an isis magazine that put this out, kind of a bookolt how to do this, but weve seen this now in france, in germany, in spain, recently. Its the weaponnization of everyday items cars, knives. It is its almost ingenious on the part of the isis propagators to put the message out that just stay where you are and create hate and discontent in your neighborhoods and some people take that message up. Sreenivasan finally, is declaring him an enemy combatant a smart move . I dont think so. I think that our law our legal system has done a tremendous job of trying people in our legal system, in the open, presenting the evidence against these individuals, and then convicting them and, basically, incarc rating them for long periods of time. Once you make an enemy combatant and create a different legal is, theres always going to be its not the way to go. We have a legal system. Sreenivasan jeffrey ringle, thank you. Sreenivasan House Republicans are scrambling to finalize a plan to cut taxes, after delaying the release of the bill to buy an extra day of negotiations. Members of the house ways and Means Committee were cloistered behind closed doors today, but President Trump spoke at a white house Cabinet Meeting. He said he would be standing beside republicans when they debuted the tax plan tomorrow. The house ways and Means Committee will unveil a historic tax plan, that will create new jobs, higher wages, which hasnt happened in many years. And now its starting to happen, im happy to tell you. But itll lead to tremendous prosperity for american families, communities, and also for our jobproducing businesses. Sreenivasan in a tweet, President Trump also called for using the tax bill to repeal obamacares individual mandate. A Navy Investigation has found that two deadly ship collisions this year were caused by preventable errors made by underprepared crews. The report blamed no one individual, but instead found a broader problem of watch crews that did not adhere to protocol. The u. S. S. Fitzgerald and u. S. S. John mccain crashes left a combined total of 17 sailors dead. Nprs news chief, michael oreskes, has resigned following accusations of sexual harassment.

Bowe bergdahl, the marine who left his post in afghanistan, in court. Recovering from Superstorm Sandy, five years later. And much more. Sreenivasan what role did social media play in russian efforts to influence the 2016 u. S. President ial election . We now know fake accounts created by moscow reached more americans than the total number of u. S. Citizens who voted. For the record, the newshour has worked with both facebook and twitter. The three tech giants were back on capitol hill today. Appearing before two separate congressional intelligence committees, facebook, twitter and google lawyers faced tougher questions than yesterday. First, at the Senate Intelligence committee. The democrat from california, Dianne Feinstein i must say, i dont think you get it. That what were talking about is a cataclysmic change. What were talking about is the beginning of cyber warfare. We are not going to go away, gentleman. And this is a very big deal. Sreenivasan yesterday, facebook admitted that from june 2015 to august 2017, 120 fake russian accounts posted 80,000 times and reached as many as 126 million americans. That number was revised to nearly 150 million today, as 16 million more people were reached by russian instagram posts. All three companies admitted fault, again. Facebooks general counsel, colin stretch the fact that foreign actors were able to use our platform to exploit that openness is a deeply painful lesson for us, and one were focused on learning from going forward. Sreenivasan the representatives vowed to invest more money, time and people to do better. At times, lawmakers used the hearing to draw partisan lines on russias impact on the election. Republican marco rubio these operations, theyre not limited to 2016 and not limited to the president ial race, and they continue to this day. They are much more widespread than one election, and it is about our general political climate. Is that correct . I would certainly agree with that statement, senator. Sreenivasan democratic senator from new mexico, Martin Henrich last month, President Trump called russianpurchased facebook ads a hoax. Are they, in fact, a hoax . No. The existence of those ads were on facebook, and it was not a hoax. Sreenivasan the House Intelligence Committee released dozens of those ads, some exhibited with blownup versions. Lawmakers chided facebook for their existence. All of the ads focused on hot button, divisive issues, one for an event called down with hillary by the group being patriotic. Another mirroring the social movement, black lives matter. Back on the senate side, twitter was singled out multiple times. The republican senator from arkansas, tom cotton, questioned where twitters loyalties lie. Is it biased to side with america over our adversaries . We try to be unbiased across the world. Sreenivasan top democratic on the Senate Committee mark warner expressed doubt over twitters claim it found only about 2,800 accounts linked to russian operatives. Im concerned that twitter seems to be vastly underestimating the numb of fake accounts and bots pushing disinformation. Independent researchers have estimated that up to 15 of active twitter accounts or potentially 48 million accounts are fake or automated. Sreenivasan representatives from each company said none has yet to identify the full scope of russian interference on their platforms. Sreenivasan the sentencing phase of u. S. Army Sergeant Bowe bergdahls Court Martial neared its end today, at fort bragg, north carolina. The soldier pled guilty to severe charges, including desertion and misbehavior before the enemy, which carry heavy prison terms. Bergdahl was captured by the taliban in 2009 after he walked away from a military outpost in eastern afghanistan; he was held in captivity for five years. The Obama Administration engineered a controversial prisoner swap with the taliban in 2014 for his release.
