because the only other thing isis does better than killing is stealing. ebola is a virus and one of the cruelest ways to die. a health catastrophe if ebola is not stopped. welcome to "the lead," i'm jim sciutto filling in for jake tapper. we begin with the world lead. the u.s. has put a ton of faith into this man for taking on isis terrorists but today, the brand-new prime minister casually uncovered this story. that his government uncovered a plot that isis was going to attack a subway in london. a senior white house source says that the prime minister didn't even bring it up in meetings with secretary of state john kerry and with president obama. we're keeping our eyes now on a news conference scheduled by the mayor of new york. that's set to begin in a moment. live pictures there. first of all, i want to bring in cropped pamela brown. she just got out of a meeting with the fbi director, james comey. what did the fbi director say? they said that they have heard nothing about this. does he treat it with credibility. >> reporter: that's exactly what james comey said. he was reading reports on what the prime minister said right before this meeting and said that his intelligence folks hadn't heard anything about it. obviously this would be front and center on his radar. so with that said, though, officials say they are assessing the validity of this threat but really across the board, jim, the white house intelligence officials are saying, look, this is the first we're hearing about this. this was not mentioned in the meeting between the prime minister of iraq and the president and secretary kerry. of course, we're going to assess this. but so far, there's been nothing to lend credence to this threat. jim? >> it's quite a way to get it out there. i'm from new york and i'm hearing from family and friends that are truly worried about it. i know the fbi director commented on khorasan and that they may be bent on attacking u.s. airliners. what did he say about whether and how much u.s. air strikes have disrupted these plots under way? >> reporter: i asked him that and he said he's not confident at all. he says it's top of his list until he hears otherwise. he's not received the final assessment of the strike. so there have only been preliminary assessments. but he says, as far as he's concerned, this group khorasan could be plotting to attack the west. as we learned from sources, jim, from intelligent sources, the group had apparently acquired materials and was in an advanced stage of plotting to attack the west. and james comey acknowledged that they are in an intelligence black hole in syria. it's a black hole. given the limited visibility they had, they were concerned that this group could launch an attack tomorrow, next week or months from now. they felt like they had to act fast. jim, you know this just as well as anyone, these are seasoned al qaeda leaders in this khorasan group and they probably knew the u.s. was after them and so they have a reasonable -- u.s. officials have a reasonable assumption that some of the leaders could have dispersed from the buildings that was targeted. >> we always imagine that intelligence is exact science. thanks very much to pamela brown down at the fbi. i want to get more on this with paul cruishank. based on what we heard so far, when you heard that warning from the iraqi prime minister, did it sound credible to you and do intelligent sources consider it credible? >> jim, this comes from iraqi interrogations that isis fighters captured on the battlefield in iraq and these are notorious for providing unrereliable information. it's not clear whether they cross-checked this information. perhaps they were making it up. perhaps they were saying this under duress. not at all clear that this information actually checks out. there is concern that isis could, in the future, prioritize launching attacks on western targets. they have up to 1,000 westerners in their ranks, tens and millions of cash reserves. they have training facilities as well. they have all of this capability in syria. there's a window of vulnerability because the united states has only just started as strikes in syria. the concern is that they could actually launch attacks in the future. in three to six months we could see plots from this, jim. >> you believe that this intelligence was a source from a captured interrogation? >> i believe that's what the iraqis are putting out. >> we're joined by robert mcfad den, the senior vice president and interrogation specialist. if, indeed, paul, that is the source of the particular warning and we know that, as paul noted, things that come out of interrogation is not necessarily reliable because of the fact that people will say anything in an interrogation, especially if forceful methods are used. does that fact, that sourcing give you any questions about the threat? >> highly unlikely from battlefield interviews and interrogation that say foot soldiers, if that turns out to be case, would have that information. on the other hand, if the prime minister said that they captured, i don't think that's much of a plausible scenario at all. although, we keep in mind that after aviation targets, subways and rail systems are probably the second most biggest exploited category to instill fear, if not target. >> no question. we know that's a group that al qaeda has attempted in new york specifically. there was a disrupted plot there a few years ago. paul, i wonder if i can ask you, there's been a lot of concern when you start dropping bombs on these groups whether it's isis or khorasan, that that shakes the hornet's nest and that gets them to want to strike back as quickly as they can to take revenge. is that something that intelligence officials are treating now as a concern? >> jake, very, very seriously indeed. the audio take that was put out declared war against the united states. said they would eventually launch attacks on the u.s. homeland. both in europe and the united states. they have not had specific programs to train westerns in the kind of bombs that you can make in the west yet but the concern is that they will initiate crash be programs to do that, just like al qaeda did in the years after 9/11. >> these groups are not relevant unless they are in the news, sadly. james comey telling our pamela brown when asked, did he think the air strikes on khorasan inside syria disrupted the imminent plots was a strike for those threats? he said he's not confident that the air strikes did that. does this get to the point -- and we're watching them play out on our screen -- as devastating as they seem, how much do they actually do to disrupt small, cagy terrorist groups from carrying out attacks? >> as stated, our programs here as well as from administration officials, those kinds of attacks are really never designed to completely destroy by themselves and especially a small cell, an al qaeda cell, what we're calling the khorasan group. i find of greater interest that the fbi director said that because that would indicate intelligence so far, there's no indication as to the degree or depth that this cell was disrupted, killed, injured, that sort of thing. so it remains a concern but also keeping in mind that al qaeda in its diminished form, the goal has always been to cause revolution, if you will, through worldwide big terrorism events. al qaeda is still there and even more importantly the al qaeda philosophy is. that's something to be considered. >> no question. it is a nervous time for sure. robert mcfadden, paul cruickshank, thank you for joining us. the u.s. and allies continue their campaign to degrade and destroy isis as well as khorasan. in the past 24 hours, coalition jets took a new target, oil refineries, robbery and extortion to become a self-sustaining monster on their rampage now across two middle eastern countries. >> this is just the beginning. >> just the beginning of a campaign the pentagon now says may take years. air strikes overnight killed 14 isis militants in syria, according to a human rights group. the u.s. and france striking more vehicles and warehouses inside iraq. and now the international coalition fighting isis is growing. isis, in its propaganda at least, remains uncowed, one video showing the stronghold of raqqa unharmed, with isis fighters even singing. but according to the pentagon, the terrorists' song was drowned out by this. 41 precision guided bombs dropped last night, by 16 fighter aircraft. six from the u.s., ten from coalition air forces. united arab emirates and saudi arabia. assets that u.s. forces are hoping to simultaneously disable and preserve. >> we want to keep some infrastructure available in the hopes that it can be -- these refineries can be used again one day by the moderate opposition. >> reporter: the shocking beheadings of isis were the spark for this campaign. >> we are an islamic army. >> reporter: cnn has learned that agencies have determined the identity of the man speaking in these isis execution videos of americans james foley and steven sotloff and british david haines. the united arab emirates first female pilot, flying in the face of a group known amongst its many acts of violence for its brutality towards women. coming up, isis still taunting the u.s. despite more air strikes. so what has this coalition accomplished when it comes to stopping this terror group? we'll take a closer look at the reality on the ground. plus, a dire prediction that the number of ebola cases could run to 1.4 million in just a few months. now president obama is calling on the world to step up its response but will that be enough?

>> tom, one quick interruption. i want to bring our viewers to a live picture of new york where mayor de blasio is going to talk about the threat. >> focused on this issue every day they are ever vigilant regarding any security threats to our city. we pride ourselves in close cooperation with our federal partners. commissioner bratton and i met earlier with the assistant fbi director who is here with us today. we're in close coordination with the government and all we are doing and nypd intelligence bureau, which everyone knows is the leader in terms of this work and local law enforcement all over the country has assessed the statements of the iraqi prime minister. and at this point, finds no specific, credible threat. this city operates on heightened vigilance on a daily basis. that is true every week. we're going to always be mindful of any new information that we she receive. we're going to act accordingly. new yorkers can be assure, this is normal for all of us and the nypd. the commissioner will talk about some of the specific actions being taken to ensure that our resources are in place and that are vigilance is intense. but everyone should know, the most important fact is we are convinced that new yorkers are safe, that people should go about their normal routine. terrorists want us to live in fear. we refuse to live in fear. and we, at the same time, will be watching 24/7 for any indication of a problem that we have to address in a specific manner. i've said many times, i want to say it again, that the people of this city have an important role to play. the phrase when you see something, say something, is not an empty phrase. it's real. the law enforcement depends on every day events to alert us of any threats. it's important that every day new yorkers act as their partners. with that, i'll pass this to bill bratton and we commend them for all the work they do to keep us safe every day. commissioner bratton? >> i'll echo the mayor's comment that at the moment we do not have any confirmed threat directed against new york city or its subway system. a lot of the current concern is based, apparently, on a press report this morning of comments made by the prime minister for the country of iraq. we were first notified of that a.p. report while we were attending a funeral for a police officer, michael williams, who was killed in a traffic accident this past sunday. but immediately based on that initial a.p. report, we were on a very high state of alert here in new york city due to the fact that many world leaders were here and many are still here in new york city. in addition to what we already had in place that we also put content general see plans far in advance to increase our activities, particularly in the subways with the initial seemed to focus on the subways. subsequent reporting, clarification of the prime minister's remarks, clarified that it was not specifically focused on subways but we err on the side of caution and preparation. so we have put 450 subway stations significantly increased resources. every precinct was notified immediately and began having the precinct stations checked throughout the city. additionally, we brought in all of our emergency service officers, the teams that you see in the city so we now have hercules teams, the heavy-armed and the dogs in all five boroughs. they will be checking bags at several stations to determine if any explosives may be coming into the system. we've notified our 13,000 security companies throughout new york about the initial information and what we are doing in response to it. additionally, lower manhattan security initiative, the 7,000 cameras that we've operated, have been enhanced with additional observation. we have held over a number of our officers from the day tour going into the evening hours until we get a complete clarification that the prime minister's remarks in fact did not have any credible information, that u.s. and new york city intelligence services were not aware of. at this time, the people of this city should feel very comfortable and secure moving through the subways. we want to train loaded with a lot of yankees' fans heading up to yankee stadium. >> you heard it there, both the new york city commissioner and mayor de blasio saying that there is no credible threat despite comments earlier in the day by prime minister al abadi. the city remains ever vigilant and new yorkers today should go about their daily lives. the police commissioner going on to say that as the initial reports of the attack -- of the threat came out, that they put contingency plans in place in the subway system as a precaution. i want to bring back in paul cruickshank. now the mayor and police commissioner had knocked down the threat. >> pouring a lot of cold water over this threat. they seem to believe it's not specific, that it's not particularly credible. but, of course, we know that terrorists want to attack new york. that's pretty much their top target and want to attack new york subway system. we've seen plots in the past from al qaeda. they think that could make a very, very big economic impact on the united states. anybody who lives in new york realizes that the subways are absolutely crucial to this city getting around. >> we've witnessed over the course of that the worst way possible to get information intelligence out there, unconfirmed and now had people worried but we had both de blasio and bratton saying that americans should feel very comfortable. that's a relief. coming up, a country completely overwhelmed at how rapidly the killer ebola virus is spreading. here in the u.s. right now, he's going to join me next. plus, president obama expected to speak on eric holder's resignation. that's any minute as critics fire off complaints about the attorney general. we're going to go live to that ahead as well. ♪ want to change the world?

holder. let's go live to the white house. >> follows the full burden proving to the world that we really mean it when we say all men are created free and equal before the law. as one of the longest serving attorney generals in the american history, eric holder has held that burden. he came to me this summer and said he thought six years was a pretty good run. i imagine his family agrees. like me, eric married up. he and his wife, dr. sharon malone, a nationally renowned ob/gyn, and i know the kids are excited to get their dad back for a while. eric has agreed to stay on with attorney general until i nominate a successor, and that successor is confirmed by the senate. which means, he'll have a chance to add to a proud career of public service, one that began nearly 40 years ago as a young prosecutor in the department that he now runs. he was there for 12 years taking on political corruption until president reagan named him to the bench as a judge. later, president clinton called him back. so all told, eric has served at the justice department under six presidents of both parties. including a several stint for george w. bush's first term. and through it all, he's shown a keep and abiding fidelity to one of our most cherished ideals, which is equal justice. i chose him as attorney general because he believes, as i do, that justice is not just an abstract theory. it's a living and breathing principle. it's about how our laws interact with our daily lives. it's about whether we can make an honest living, provide for our families, whether we feel safe in our own communities and welcome in our own country. the words of our founders apply to every single one of us and not just one. that's why i made him america's lawyer. the people's lawyer. that. coulds with a big portfolio. counterterrorism to civil rights, public corruption to white collar crime and alongside the incredible men and women of the justice department, men and women that i promise you he's proud of and will deeply miss, eric has done a superb job. he's worked side-by-side with our intelligence committee and the homeland security to counter violent extremism. on his watch, federal courts have successfully uncovered several plots proving that the world's justice system is capable of delivering justice for the world's most wanted terrorists. he's rooted out corruption and fought violent crime. under his watch a few years ago, the fbi carried out the largest mafia takedown in history. he's worked closely with law enforcement officers to make sure that they've got the resources to get the jobs done and to make sure when budgets took a hit, thousands of cops were able to stay on the beat nationwide. he's helped safeguard our markets from manipulation and consumers from financial fraud. since 2009, the justice department has brought more than 60 cases against financial institutions and won some of the largest settlements in history related to the financial crisis, recovering $85 billion, much of it returned to ordinary americans who were badly hurt. he's worked passionately to make sure our criminal justice systems remains the best in the world. he knows too many outdated policies and addressed unfair sentencing disparities, reworked mandatory minimums and alternatives to incarceration. thanks to his efforts, since i took office, the overall crime rate and the overall incarceration rate have gone down by about 10%. that's the first time that they've declined together at the same time in more than 40 years. eric's proudest achievement would be the conscious of the building and that's the civil rights division. he's been relentless against attacks on the voting rights act. because no citizen, including our service members, should have to jump through hoops to exercise their most fundamental right. he's made it harder for law enforcement to do its job. under his watch, the department has brought a record number of prosecutions for hate crimes because no one should fear walking down the street because of the color of their skin. he's advanced the cause of justice for native americans working closely with their communities. and several years he recommended that our government stop defending the defense of marriage act. a decision that was vindicated by the supreme court and opened the door to federal recognition of same-sex marriage and federal benefits for same-sex couples. that's a pretty good track record. eric's father and his wife raised their son to believe that this country's promise was real. and that son grew up to become attorney general of the united states. that's why he's worked so hard, not just in my administration but for decades to open up this country to more striving kids, to make sure that those words, life, liberty and the pursuit of happiness are made real for all of us. soon, eric, sharon and their kids will be freer to pursue more happiness of their own and thanks to eric's efforts, so will more americans. regardless of race, religion, gender, or creed, sexual orientation or disability who will receive equal and fair treatment under the law. so i just want to say thank you to eric. thank you to the men and women of the justice department who worked day in and out for the american people and we could not be more grateful for everything that you've done, not just for me and the administration but for our country. [ applause ] >> i come to this moment with very mixed emotions. proud of what the men and women of the department of justice have accomplished over the last six years and, at the same time, very sad that i will not be a formal part. a formal part of the great things that this department and this president will have accomplished over the next two. i want to thank you, mr. president, for the opportunity that you gave me to serve and for giving me the greatest honor of my professional life. we have been great colleagues. but the bonds between us are much deeper than that. in good times and in bad, in things personal and in things professional, you have been there for me. i'm proud to call you my friend. i'm also grateful for the support you have given me and the department as we have made real the visions that you and i have always shared. i often think of those early talks between us, about how our belief that we might help to craft a more perfect union. what remains to be done is real over the last six years. and your administration has fought to protect the most sacred of the rights of americans, the right to vote. we have begun to realize the promise of equality for our brothers and sisters and their families. we have begun to significantly reconnect those who bravely served in law enforcement with the communities that they protect. we have kept faith with our belief in the power of the greatest judicial system in the world has ever known, to fairly and effectively adjudicate any cases that are brought before it, including those that involve the security of the nation that we both love so dearly. we have taken steps to protect the environment and make more fair the rules that are commercial enterprises operate. and we have held accountable those who would harm the american people, either through violent means or the misuse of economic or political power. i have loved the department of justice ever since i was a young boy. i watched robert kennedy prove during the civil rights movement how the department can and must always be a force for that which is right. i hope that i have done honor to the faith that you have placed in me, mr. president, and to the legacy of all those who have served before me. i would also like to thank the vice president, who i have known for so many years and in whom i have found great wisdom, unwavering support and a shared vision of what america can and should be. i want to recognize my good friend, valerie jarrett, who i've been fortunate to work with from the beginning of what started as an improbable effort from a young senator of illinois who we were both right to believe would achieve greatness. i've had the opportunity to serve in your distinguished cabinet and worked with a white house chief of staff, white house staff, abely led by dennis mcdonough and each of the men and women i have come to known will be lifelong friends. whatever my accomplishments, they could not have been achieved without the love and support and guidance of who team not with me today. my parents, eric and william holder, nurtured me in my accomplishment and made us believe in the value of individual effort and the greatness of this nation. my time in public service, which now comes to an end, would not have been possible without the sacrifices too often unfair made by the three kids the father could ask for, thank you, mai, brooke, and finally, i want to thank the woman who sacrificed the most and allowed me to follow my dreams. she's the foundation of all that our family is and the basis of all that i have become. my wife sharon is the unsung hero and she is my life partner. thank you for all that you have done, i love you. in the months ahead, i will leave the department of justice but i will never, i will never leave the work. i will continue to serve and try to find ways to make our nation even more true to its founding ideals. i want to thank the dedicated public servants who formed the backbone of the united states department of justice for their tireless work over the past six years, the efforts they will continue and for the progress that they made and that will outlast us all. and i want to thank you all for joining me on a journey that now moves in another direction but that will always be guided by the pursuit of justice and aimed at the north star. thank you. [ applause ] >> well, an emotional and heartfelt good-bye from attorney general eric holder there describing his mixed emotions even breaking into tears a bit as he thanked his parents and children and wife there. also, an emotional moment for the president who called it bittersweet. the first african-american president saying good-bye to the first african-american attorney general. we're joined by justice reporter evan perez. he's with me as well as jim acosta at the white house. i wonder if i can begin with you, jim. the president said six years is a pretty good run. but this was both a strong professional, political and also personal relationship, wasn't it? >> reporter: it really was, jim. i want to notice what was said at the very end there. eric holder hinted at the timeline for his eventual departure. he said i'll be leaving the department of justice in the months ahead. you are right, they have been well known as being close friends, that friendship getting even closer during eric holder's time as attorney general. i'm told by one official that the two spend a good amount of time together up at martha's vineyard in august when the president was on vacation. eric holder was always on vacation up at martha's vineyard and it was during that time that the attorney general likely brought up this idea, which he's brought up before, that he would like to stand down as attorney general. i've been told that he would ask him to please consider to stay on longer but this time around the idea started gaming steam and resulted in the announcement today, jim. no question about it, jim, they are very tight. >> evan, i know you spoke to the attorney general holder. as you spoke to him, did you get a sense that he's ready to go? >> he feels that he's going out on top. frankly, certainly, we have written and talked a lot about the seizure of the phone records and the controversies over the fast and furious. and a successful visit in ferguson, missouri, where he helped calm tensions over the shooting of michael brown. he believes that he's accomplished a lot with the gay rights. the president mentioned that he was behind defending the defense of marriage act. he said, i think i go out accomplishing a great deal in the areas that are of importance to me. i'm satisfied with the work that we have done. he feels like his work is done. >> it's an interesting legacy, which you get at there. he was a civil rights champion for sure. civil rights when we're talking about african-american issues like ferguson but also gay rights and also issues with civil liberties. this administration under him went after reporters, certainly, for divulging secrets, et cetera, more than anybody before. that's a conflicting legacy, isn't it? >> yes. one of the things i've talked to him about is, he's the one that signs the warrants that the nsa uses to do its surveillance. and so he didn't get a lot of the attention on that but he is also part of that, part of the picture there in trying to reshape how the nsa and fbi and spy agencies do their work. >> so we've got to play the parlor game because this is washington and he's leaving. who is likely to take his place? >> we don't know of any favorites yet. the white house has started working on some names and probably have started to talk to some people but some of the names, don, who is a solicitor general who argued the obamacare case. kathy rumbler who just left the white house and having the legacy of alberto gonzales, the bush white house counsel. >> and duvall patrick. >> always on the list. and lynch and bharara. >> incredible conviction rate. >> exactly. jeh johnson. he's now the homeland security secretary. and harris, who is a big star in the democratic circle. she's the attorney general of california. she's also well-thought of. >> how quickly do you expect the position to be filled? he said he's going to stay until he's replaced. >> this is going to give republicans a little bit of a push to approve someone very quickly. >> no love lost? >> no love lost from any of them. >> thank you very much. coming up next, president obama with a warning to the world. help stop ebola before it's too late. we're going to talk to a doctor who witnessed the disease explode before his very eyes. i hait's tough, but severi've managed.ease. but managing my symptoms was all i was doing. so when i finally told my doctor, he said humira is for adults like me who have tried other medications but still experience the symptoms of moderate to severe crohn's disease. and that in clinical studies, the majority of patients on humira saw significant symptom relief. and many achieved remission. humira can lower your ability to fight infections, including tuberculosis. serious, sometimes fatal infections and cancers, including lymphoma, have happened; as have blood, liver, and nervous system problems, serious allergic reactions, and new or worsening heart failure. before treatment, get tested for tb. tell your doctor if you've been to areas where certain fungal infections are common, and if you've had tb, hepatitis b, are prone to infections, or have flu-like symptoms or sores. don't start humira if you have an infection. if you're still just managing your symptoms, ask your gastroenterologist about humira. with humira, remission is possible. welcome back to "the lead." in other world news, what started as a regional crisis is now being cast as a threat to health and security of the world. today, president obama warned global leaders at the u.n. general assembly that without quick action, the ebola outbreak could become a humanitarian catastrophe. there are 6,000 cases and nearly 3,000 people have died from the virus. the number of cases is doubling every two weeks in liberia. i spoke with the foreign minister about how the explosive pace of this outbreak is overwhelming government and health workers in the region. >> ebola is a challenge that is having a multidimensional impact on our country and is decimating our health care workers. we have lost about 1,700 compatriots. yes, it's scary but we take it to be a call to action for the global community. because if the global community has the good sense to prevent what has happened in a do-nothing scenario, everyone should have the good conscience to prevent that from happening. >> that's the liberian foreign minister speaking there. the question is, why did it take so long for the world to take notice? i'm joined by dr. paul farmer, an infectious disease doctor at harvard university. dr. farmer, i know that you recently visited liberia, which is right at the epicenter of this crisis. do you have any sense that this is becoming under control because w.h.o. and others have described it as out of control. >> it's not coming under control yet. but one of the encouraging things about this last couple of days is there is widespread recognition that this is an out-of-control epidemic and there are the system on the part of west africa. >> you talk about what wasn't done earlier. in a recent op-ed, "the epidemic in west africa is a tragedy but more than that, the response to it has been a gross failure. its a classic case where early action could have saved lives and money." what was missing? >> what was misses wag resources and they are tied to attention. i was there in sierra leone in june and wish we would have sounded the alarm more and more effectively, staff stuff, safe space in which to work and see patients and also a system sort of approach. and none of those were available in those three countries in may and june when this could have been slowed and averted and now it has gotten out of control but we still need all of those things and need to rebuild the health systems of those countries. >> the countries here in the west have a much better health care system to respond to this but as it expands possibly to more than a million cases in west africa, does it become a threat to europe and the u.s.? >> well, sure, it's a threat to every part of the globe because the globe is connected through commerce and movement of people and it's now -- this is -- even though it started as a disease of animals, it's jumped into the human population as being spread from person to person because, again, the health care workers and families lack the tools of the trade to protect themselves with protective equipment and we have to address that shortage if we want to stop the epidemic. i believe we will. >> that's refreshing to hear but the idea that this is a global crisis is certainly a sobering thought. >> thank you for having me. coming up on our money lead, bad day on wall street. the stock market suffers its worse slide in nearly two months. how much does your new bigger than the i'm phone have to do with that?
