starting with a frank admission from president obama. he flat out said he doesn't have a plan yet to go after isis in syria, its home base. here's how he put it. >> i have consulted with congress throughout this process. i am confident that as commander in chief i have the authorities the engage in the acts that we are conducting currently. as our strategy develops, we will continue to consult with congress and i do think it will be important for congress to weigh in and -- or that our consultations with congress continue to develop so that the american people are part of the debate. but i don't want to put the cart before the horse. we don't have a strategy yet. >> no strategy yet, even though just today isis said it's executed at least 250 syrian soldiers at an air base in a northeastern city in syria. we'll have much more on that claim in a moment. the terror group also posted a video that it says shows

captured kurdish soldiers wearing orange jump suits like the one james foley was wearing when he was beheaded. the video shows three masked men who appear to decapitate a man in front of a mosque in mosul. we can't verify the video's authenticity. tonight the fate of journalist steven sotloff is unknown. isis has threatened to kill him as well. jim acosta joins us now. so the president wanted to tamp down reports that air strikes in syria were imminent and his critics quickly jumped on what he said about not having a strategy and the white house has tried to basically do damage control. >> that's right. he was trying to end that speculation that he was on the verge of ordering air strikes on isis targets in syria. you know, one white house official told me after the president's comments that they thought the speculation was getting out of control so the president wanted to go out there and put an end tobl that. but it was in that context when he was asked about whether or not he would go to congress to authorize military action in syria that the president used those words "we don't have a strategy yet" and that of course

just went aban bananas on twitt use a technical term. you and i know what that is like with a poorly phrased sound bite. this can take off and that's what happened. instantly the white house jumped into damage control mode. josh earnest went on "the situation room" with wolf blitzer just about an hour after the president wrapped up his remarks and explained that the president was referring to his strategy on isis in syria. the white house argues that the president does have an overall strategy for isis, but they want more international cooperation. they don't see countries in the region really doing enough and the president doesn't feel like really committing u.s. forces to that kind of fight without more partners in the region. so the president is dispatching secretary of state john kerry to the region after the nato summit next week. >> and the u.s. really does not want to go it alone in terms of trying to deal with isis in the region. >> that's right. and with all of this talk about the president saying we don't have a strategy yet, a lot of

people have not focused on some of the other things that he said during this briefing. one thing that struck me, anderson, is when the president almost chastised some of the countries in the middle east, what he called state actors that he said are ambivalent about terrorism. ambivalent about isis. he said that there are some states in the region that are contributing money to terrorist organizations because they think it's a good policy. it perhaps keeps them safe. the president really wants to go after that problem. the other issue that he mentioned is the fact that the sunnis in iraq, and you've looked at this extensively, anderson, they just don't feel like they're part of the iraqi government. so because of that, many of those forces have joined up with isis and has made the situation in iraq almost -- almost impossible to manage. so the president wants to make sure that the iraqis are keeping their word and saying that they will put together a more unified government. that's also on the president's agenda. >> jim acosta, appreciate the update. joining me now is gloria

borger. the president saying he has no strategy yet. obviously an error in the use of the words. critics say it wasn't just an error, they say the white house doesn't have a strategy. you're hearing, though, new information about how soon we might hear a decision. >> i spoke with one senior official this afternoon and this person said to me that it could be within a week or so. but like everything else, that could certainly stretch out. as jim acosta was just saying, the president dispatched the secretary of state john kerry to go to the region after the nato summit. and i'm told by the senior administration official that the president wants kerry to be his eyes and ears because the president wants to know where the countries in the region stand and what they're willing to do vis-a-vis use of force, if that's what the president decides to go for. >> are we likely to see the president go to congress to seek authorization? because there's probably some folks in congress with midterm

election coming up who would be happy for the president not to basically put them on the record. >> you think? the senior administration official said, look, privately they're hearing from members of congress who say please don't make us vote on the authorization of force 60 days before an election. that's very difficult. you do have some members of congress on the liberal side and on the republican side who have come out and said we do need to vote on this. we can't hide on this vote. but it's a concern over at the white house i'm told about what exactly they could get out of congress. remember a year ago, and of course it was a different circumstance with syria, the president was considering the use of force and knew that he couldn't get a vote to use force at that time. this is a different situation. we've had a beheading there. isis, the public certainly knows more about the dangers of isis, but the white house still isn't sure what it could get and so in the end, anderson, they may decide not to go to congress

before the election and do what they can until then. we just don't know. >> gloria, appreciate it. thanks very much. as we said, isis claimed today to execute at least 250 syrian soldiers at an air base in northeastern syria. we're not going to show you the killings. we do want to warn you even the aftermath is tough to look at. anna joins me with the latest. anna, what more do we know about this video of isis claiming to have killed hundreds of syrian troops? >> anderson, it's just sickening and gruesome individual yoechlt it starts by showing syrian soldiers marching through the desert, stripped to their underwear, most of them with their hands behind their head. the next image that we see is a pile of bloody bodies and then the camera turns. and you just see body after body after body of dead soldiers lying face down in the dirt. it is absolutely gruesome. isis claims that they captured

250 syrian soldiers during their week-long battle to take a military base. it was the last strong hold for bashar al assad's regime in that area. they say those 250 soldiers were executed. these are fundamentally prisoners of war. if that video wasn't bad enough, several hours later isis posted another video on youtube. this time of kurdish forces who have been captured here in iraq. it shows them dressed in orange jump suits, the same jumpsuit that american journalist james foley was wearing when he was brutally beheaded in that video last week. you hear these kurdish soldiers make this appeal to their president here in kurdistan to stop participating with the united states and allowing the air strikes to continue in this country and at the very end of the video, anderson, we see one of those soldiers beheaded in front of a mosque in mosul. this being, of course, iraq's

second largest city, which was claimed by isis back in june. but certainly both these videos and these abhorrent acts really defining what isis is all about, anderson. >> and there's renewed fighting, i understand, between isis and kurdish peshmerga forces near the mosul dam? >> reporter: yeah, absolutely. that has been under way for some time, but a mass operation there launched by the kurdish, the peshmerga forces, earlier today. obviously they managed to claim back the mosul dam last week. we were there when they did that. but isis is still in those surrounding towns and villages. now, as they were being pushed out, they lit oil wells, exploded pipelines. the militants really just trying to cause destruction and also cover for what they are doing there, laying ieds, land mines in buildings, in villages, and some of the peshmerga sustaining

casualties along the way, obviously slowing their advance as they try to push them out of this very important area. but we understand from the kurdish forces that this is an ongoing operation, anderson, and will be continuing for some days to come. >> the brutality is just extraordinary. anna, thank you. the u.s. seems close to verifying the identity of the second american killed while fighting for isis in syria. the first one was a 33-year-old man named douglas macarthur mccain. his death was easier to verify because of his neck tattoo. counterterrorism intelligence officials are trying to verify reports this is the second one. a family friend says he is indeed the second american killed. as we have been reporting there have been others that left their all-american hometowns to join a jihad and there are connections between them. for example, when he followed douglas mccar thur mccain's path back to his roots in the united states, it leads you to minnesota where he was friends with another teenager at the time, a guy named troy castagar. they both ended up fighting for

extremist groups far from the minneapolis city. jason carroll spoke with his mother. >> reporter: for years troy castagar and doug mccain were the picture of the average teenage american boys. they grew up in minneapolis. both loved playing basketball and were in some ways inseparable. >> troy had -- there's quite a few people who i think you would say -- they would say they were best friends. and doug was one of those really close friends. he spent a lot of time at our house. he went to family gatherings with us. they played basketball together. >> so how did two respectful young men go from this image to this? >> this is the real disneyland. you need to come here and join us. >> reporter: this recruitment video was posted from the militant group al shabaab. both castagar and mccain ended up fighting for terrorists overseas. mccain killed in syria just days ago. castagar killed in 2009 in

somalia. his mother still trying to understand how it all happened. >> i'll never not have that pain and that bitterness, but by trying to fill my life with joy and recognize the gifts and the beauty of the world, it makes it easier. >> reporter: castagar's mother says he started having trouble at 16. he began using drugs and was searching for help and spiritual guidance. >> and he found comfort in turning to the koran. >> so then he became muslim. and i don't know exactly how that happened. he had some friends who were muslims. there was some friends who were somali who had immigrated here. it was great for him. like he all of a sudden was like i have my boy back. his eyes were bright again. >> reporter: he said he was going to kenya to study the koran, but his destination ended up being somalia. he had spent nearly a year overseas with little communication. then in july, 2009, the fbi came to his mother's home.

>> they said he could have been recruited. i had no clue that he was going into a dangerous situation in that way. or to fight. and i think he knew -- >> reporter: weeks after that visit, her son was dead. >> were there any warning signs along the way? >> with doug for sure there were no warning signs because i just haven't been around him for a long time. the one thing that i thought was really strange with troy is that they -- that someone, they, were willing to pay for him to come to kenya. i really questioned that. i think they were manipulated. i don't think they knew what they were -- fully what they were part of. >> jason joins me now. do we know, did he have any connection to the somali community in minneapolis before he left? >> he did. his mother talked about that, anderson. he made friends here who were somali. and then she also said that he

felt sorry for the somali people. he felt many of them had been o owe pressed and was looking for a way to get over there and help them. clearly he went over there, lost his way and ended up siding with a terrorist organization. >> jason carroll, thanks. quick reminder, set your dvrs to watch 360 whenever you like. coming up, the shooting that led to protests in ferguson, missouri, possibly caught on audio tape. tonight there's new evidence that the audio tape of the michael brown shooting is actually legit. we'll tell you the new information that's been learned. that's next. that's good. i know right? gevalia. so what we're looking for is a way to "plus" our accounting firm's mobile plan. and "minus" our expenses. perfect timing. we're offering our best-ever pricing on mobile plans for business. run the numbers on that. well, unlimited talk and text, and ten gigs of data for the five of you would be... one-seventy-five a month. good calculating kyle.

good job kyle. you just made partner. our best-ever pricing on mobile share value plans for business. now with a $100 bill credit for every business line you add. hey there, i just got my bill, and i see that it includes my fico® credit score. yup, you get it free each month to help you avoid surprises with your credit. good. i hate surprises. surprise! at discover, we treat you like you'd treat you. get the it card and see your fico® credit score. so when my moderate to severe chronic plaque psoriasis them. was also on display, i'd had it. i finally had a serious talk with my dermatologist. this time, he prescribed humira-adalimumab. humira helps to clear the surface of my skin by actually working inside my body. in clinical trials, most adults with moderate to severe plaque psoriasis saw 75% skin clearance. and the majority of people were clear or almost clear in just 4 months.

humira can lower your ability to fight infections, including tuberculosis. serious, sometimes fatal events, such as infections, lymphoma, or other types of cancer have happened. blood, liver and nervous system problems, serious allergic reactions, and new or worsening heart failure have occurred. before starting humira, your doctor should test you for tb. ask your doctor if you live in or have been to a region where certain fungal infections are common. tell your doctor if you have had tb, hepatitis b, are prone to infections, or have symptoms such as fever, fatigue, cough, or sores. you should not start humira if you have any kind of infection. make the most of every moment. ask your dermatologist about humira, today. clearer skin is possible.

welcome back. tonight there's new ed, someone using a video chat, was evidence to record the shooting of michael brown. the company that makes the mobile app says it can verify down to the second the audio was actually recorded which is right around the time that officer darren wilson shot and killed brown. we can't independently confirm whether the shots heard are from

that incident, but here's the recording in question. listen. >> you are pretty. you are so fine. just going over some of your videos. how can i forget. >> cnn's don lemon joins me now. i've heard that a million times. i'm still creeped out by what the guy is actually saying but i'm going to ignore that part of this entire thing. this company, glide, says the audio was recorded at the same time. what else do we know in the verification process? >> we know the time. the time is 12:02:14. this is according to glide, that they have a time stamp of that recording. and it is a recording, anderson, it's not an interactive chat. >> right, because early on a lot of people thought, i certainly thought he was actually talking with someone and i thought, okay, they can get the video on the other end of this talking to the woman he was talking to, but this was a one-way thing. he was recording something. >> why would he be recording an interactive chat. yes, he was recording. you hear him say i've been

looking at your videos. so he was recording a video back to her and it was only 12 seconds. that 12 seconds -- within that 12 seconds, they got those ten or possibly 11 shots on tape. >> because there may have been another shot earlier, because some witnesses have said there may have been a shot in whatever the tuesdssle in the vehicle. >> there was a struggle in the car, according to the witnesses that we have spoken to. you've spoken to a number of them. there was a tussle in the car and it was said a shot went off. in that 12 seconds nothing is on there, so it is believed that if the video is authentic and if there was a tussle in the car that the video started after that shot in the car. >> and you've met with the attorney for this source. >> yes. >> you first broadcast this tape. can you explain the process of how it came into your possession and what we know about the guy. you know he lives in this complex. >> he lives very close to where the shooting is. they pointed that out.

glide, the company, wanted to point that out. the attorney wanted to point that out as well. and she wanted to verify that what they are client was telling her was accurate, so she did some vetting herself, found out where he lived. as a matter of fact, she has been very transparent about this. someone who lives with him, was a former client of hers, and that's how he got in touch with her because he realized after he saw this recording, played it back, well, that may be the shots. he wasn't even sure. as she says, of the import of what he had recorded. so his roommate said i have an attorney, i think you should speak with that attorney. long story short, we had a source that said there may be a tape out there. i think that this may be the attorney. i called her, got a secretary on the phone who said she's in a meeting right now. she called back just a few minutes later and said it's strange that you would call me right now because we just met with the fbi. and so they had been -- she and her client had both been meeting with the fbi. >> and presumably they are trying to they not kaauthentica

well. that process continues. but the news today, this information coming out from glide that they have been able to verify the time. that's really a big deal. don, appreciate the update. don will be on at the top of the hour, 10:00. a short time ago, i spoke with frank piazza, audio forensic expert and mark o'mara who represented george zimmerman and attorney areva martin. mark, if it's confirmed that this is the audio of the shooting of michael brown, do you see it bolstering either side, the prosecution or the defense or do we simply not -- i mean obviously we don't know any of the forensic evidence. is it simply too early to tell? >> well, a couple of things. i do think it's going to be authenticated. it seems to be relevant in time, place and the way it happened, so i think it's going thoent katd, which means it's going to show up in a courtroom. what's interesting it does, it sort of sets the audio stage for what happened. i agree with don, it seems as though it's missing that first shot that was testified to by dorian, but the other ones i think are fairly significant.

now, whether or not they help the state or defense according to what side you want me to take, anderson, you and i have both talked about not speculating. but one thing that's interesting about that is the family's autopsy suggested that mike brown was hit six times in the front. if we presume that dorian was right and one of those shots came at the car, then five other shots came to his front but if they came at the last four, there's not enough shots, meaning that at least one of those five shots in the front had to come from the first volley. that might indicate that mike brown turned around during the first volley or was at the officer during the first volley. there was an intervening three seconds and he continues to shoot, including the two fatal shots. so from a defense perspective, this could fit in very well. prosecutor perspective might say he waited three seconds when he should have done something else when he continued to shoot. >> areva, what do you think about that pause, how

significant is that for you? >> i think it's very significant because, again, we have an unarmed teenager who what we've been hearing from the eyewitnesses, he was defenseless and he was actually surrendering. so when you hear a pause in the gunshots, it causes you to think could there have been something else this officer maybe could have done to apprehend mike brown rather than continue to shoot after the first, you know, six shots that we hear on the audio. i think it's also interesting, anderson, because we've heard a lot about the ferguson police not having dash cams or body cams. so this is an audio that presumably would be very similar if there had been a dash cam or some other kind of camera in place. so more reliable than eyewitness testimonies, which we know at this point seem to be conflicting. so i think a very important piece of information that hopefully will show up in the grand jury. >> i want to play the recording again, frank, before i just ask you about it. do we have that ready to play? let's just listen. >> you are pretty. you're so fine.

just going over some of your videos. how can i forget. >> frank, is it possible with the sophisticated kind of equipment that you have and other audio experts have that there's a lot more information on the audio tape, stuff that cannot easily be heard? >> well, you know, we spoke earlier about this a couple of days ago. there are three sections that we're hearing in the audio. there's the sound of the male voice, there is the sound of the gunshots or the environment behind it and then there's the sound of the actual room where the microphone in the phone is picking up that environmental sound. and you listen to all those things and you listen for something that's continuous. and in the case of what we're hearing there, and again i'm hearing it right now with just an ear piece, there seems to be a consistency in the environment of the room where the person actually speaking it into the microphone was. so that's something to pay attention to. >> you said also the other day and i found it fascinating is

that you can actually kind of get a signature for the ac current that's in the room. can you explain that again and why that's significant? >> sure. i'll give the shortest version i can. there's a newer technology that's been used by some forensic audio professionals that's referred to at enf. basically what it is, the current, the electrical current is actually giving out a time signature. and the electrical grid that exists here in the united states, that can be tracked and mapped. and you can create that same timeline if the electrical power current is picked up within the recorder that made the recording and then do a comparison in a wave form. it's newer technology and it's definitely can be helpful. >> that's fascinating. mark, you said the other night that you take issue with recordings like this being released because of the effect it can have on other eyewitness testimony. people basically kind of

adapting their testimony to what they hear in the media or they hear other witnesses talking about? >> here's what's going to happen. it's very normal human behavior. now that we know and everyone knows who hasn't given their testimony yet that there were ten shots with three seconds in between are going to naturally or maybe intentionally craft that and bring that into their testimony. so i think you'll see witnesses start to say when they talk about this event that's what they heard. the other side of the coin is just as important, though. every witness who has given a statement who has not stated affirmatively there were a number of shots, a pause of a few seconds and a number of other shots, now those witnesses are going to be impeachable potentially because of this new piece of evidence. that's why getting this out piecemeal is really interfering with the validity maybe or the integrity of the investigation in both sides preparing their case. >> areva, which is why it's crucial that investigators get as quickly as possible and have been getting as quickly as possible to any potential

witnesses. that's why they want to get to those eyewitnesses as quickly as possible before people start to hear, you know, what other people in the crowd are saying or people on television are saying. >> absolutely, anderson. there's some concern already that people are starting to mimic what they're hearing the other eyewitnesses talk about. but you can hear the people who are lined up for brown and believe that this was an excessive shooting saying that they're concerned that darren wilson is hearing all of these accounts and is giving him an opportunity to craft his version of events to fit with the evidence and to fit with his shooting being justified. so i think it works on both sides, both for the witnesses who are su pouring and those who are opposed. >> it's an interesting perspective. frank, appreciate you being on, areva martin, mark o'mara. the crisis in ukraine taking a new turn. russia has launched a full-scale invasion across its southern border. president obama says russia's actions will have costs and consequences. no rush, andy.

tonight ukraine has reinstated its military draft after what one ukrainian army officer calls a full-scale invasion. as many as a thousand russian troops crossing ukraine's southern border to fight alongside pro-russian separatists. nato released these salts images showing tanks and troops in and around a southern ukrainian town. moscow continues to deny it's directly aiding the rebels. here's what president obama said

today. >> russia is responsible for the violence in eastern ukraine. the violence is encouraged by russia. the separatists are trained by russia. they are armed by russia. they are funded by russia. russia has deliberately and repeatedly violated the sovereignty and territorial integrity of ukraine. and the new images of russian forces inside ukraine make that plain for the world to see. >> the question is how will the world respond. cnn's diana joins us now from ukraine. diana, what's the latest there tonight? >> reporter: well, anderson, a town on the -- pretty much on the russian border has been taken by rebel forces backed by russian tanks, russian units and supported by artillery shelling from across the border. effectively what that does is creates a southern front quite

far away from the anti-terror operation, as ukraine calls it, the conflict area, and really detracts attention from their offensive in that region, spreading ukrainian forces far thinner on the ground and making it look as if the rebels at this stage really have the upper hand, anderson. >> so is the ukrainian military, are they up to fighting on these multiple fronts? >> reporter: well, we've been talking to volunteer battalions down here who don't seem particularly enthused by the fact that they were driven out of this town. we saw a convoy of very bedraggled vehicles clearly deciding they had had enough of it. we've heard that ukraine is going to send in reinforcements and the ukrainian president poroshenko has said this is not a situation where we should panic and it is controllable. but to be honest, anderson, we've been driving around this border region and we have seen

very, very little evidence of ukrainian defenses. >> and russia is still claiming these fighters that have entered ukraine, that they aren't troops, they are, quote, volunteers, is that right? >> reporter: volunteers, yes. volunteers, if volunteers can be called people coming in with tanks. so the russian view, the russian narrative is one of looking after the people of this -- in this conflict. it is one of presenting themselves as a sort of humanitarian angel in all of this and consistently denying that it has any kind of military involvement whatsoever. >> as you said, the idea that russian volunteers could somehow get their hands on russian military tanks seems ludicrous. diana, appreciate the reporting, thank you. susan hendricks has a 360 bulletin. >> anderson, a u.s. official says the fbi is investigating hacking attacks at several top banks, including jpmorgan chase

where data was breached. a jpmorgan spokesperson says they are now working with investigators to determine the scope of that apparent breach. well, the nfl announcing tougher penalties for domestic violence and sexual assault. players will face a six-game suspension for the first incident and an indefinite ban for a second offense as well. now, this comes just weeks after commissioner roger goodell gave ravens running back ray rice just a two-game suspension for dragging his then-fiancee, now wife, from a hotel elevator and that was caught on surveillance tape. the nra is facing criticism for posting a tweet two days after a 9-year-old girl shot and killed a gun instructor while she fired the uzi. there is the video. she was visiting with her family from new jersey. well, that tweet has since been taken down, but it linked to an article promoting ways for kids to have fun at the shooting range. and, yes, he is back. toronto mayor rob ford is caught

tonight a new and sobering number in the ebola outbreak in west africa. more than 20,000. that is how many cases we could see, according to world health organization, before the outbreak is stopped. just over 3,000 people have been affected so far. more than half of those have died. today the w.h.o. issued a road map for curbing the spread of the deadly virus and said there is an urgent need to scale up the international response. we're joined with the latest from liberia where quarantines are fueling anger and fear. you visited a quarantine zone. what did you see there? what is it like? >> reporter: a lot of fear, anderson. you're right to talk about that. a lot of anger and just a lot of confusion. this has been going on for so long now. west point where we visited, you have about 70,000 people. they can't go out. no one can go into them. the food supplies are running low. this scaled-up response by that

the w.h.o. is talking about, there is time for that to have been implemented and yet nobody is seeing any aspect of that here on the ground and nobody is telling these people what their options are, when the quarantine will end or even how it will end, anderson. >> and one of the things that makes the outbreak so unprecedented is how widespread it is. it's not just this bad in liberia, but other countries as well. sierra leone, guinea, and even now nigeria in some cases. >> reporter: and you have a million people in that tri-country quarantine zone to the north of here that are facing starvation. and again, we go back to this issue of the scaled-up international response. of course people are afraid. people are afraid inside liberia. it was scary even just for us to come here. but these concerns can be managed and, you know, there are ways to protect yourself and the reality is all of the experts that we're speaking to on the ground say it's not about money, anderson, it's not about sending in supplies. what they need is people.

they need competent assets here on the ground to help get over this crisis. >> you also spoke to the cdc director, tom frieden, who was there on the ground. what did he say about what needs to happen now? >> reporter: well, he seemed really blown away, anderson, by what he found here. he said that even he hadn't expected to see this level of a crisis and he came back again to this point of not isolating liberia, not almost ceiling them off like a medieval plague. he said we will not in any way be safe. the world will not be safer if liberia isn't helped, if people try to lock the door on this. at some point, some cases will break through and that's when the danger comes. this has to be contained by people coming here on the ground and helping those suffering, anderson. >> be careful, thank you. an ebola vaccine being developed by the nih and drug maker glaxosmithkline could be tested in humans starting next month. federal officials made that announcement today. joining me tonight is chief

medical correspondent dr. sanjay gupta and dr. fouchi. doctor, this trial, can you just explain how it's going to be conducted. it's my understanding it's going to start very small and then expand. >> right. it's a phase one trial. we've had very good results with the animal study in this. it looks really good in protecting monkeys against lethal challenge of ebola but now that we're going to the next important step into humans, that's why you've got to go very slowly. once you finish that and observe them long enough for safety, it will take us until the end of the calendar year, sometime around december, then we'll know if it's safe and whether it induces the kind of response we want it to. then you go to the next stage of a broader, larger trial. >> and sanjay, in terms of preventing further outbreaks, how important could this vaccine be? >> that's a great question. i think obviously for this outbreak, given the timing dr. fauci described, it's probably not going to be available in time for this particular

outbreak. hopefully this outbreak will be over in a good way before that. it's interesting, anderson, you and i again have been on the ground in these places. part of it obviously is figuring out if this works, who should get it and that's probably a little easier said than done. and then also simply distributing it, you know, to places where it is needed. that is also a challenge. i remember somebody once said to me if the cure for aids came in the form of a clean glass of water, we still could not cure the world of aids because it's a question of not only making these medications, but also getting them to the people. >> distributing it out. dr. fauci, though, this isn't the only vaccine in the works. there are other experimental treatments. zmapp, which we've all heard about by now. why the focus on this vaccine to start the testing? >> there are a number of vaccines in the pipeline. this one is the furthest advanced in development. several have been in animal studies. we've been sponsoring and

conducting animal studies in several other candidates. so this may not be the vaccine that we get, but it certainly is a good start, at least from what we've seen with animals. >> dr. fauci, i was amazed to read this paper out this week that traced the genetic mutations of the ebola virus in this current outbreak. the fact that it's mutated, is that cause for alarm? >> well, it is somewhat a cause for alarm as long as this epidemic keeps going, what you're going to have is the possibility that the mutations will make our diagnostics less sensitive and might even impact whether or not the proteins that you're using in the vaccine might be the best choices. >> and sanjay, they were able to trace -- i'm amazed that scientists can do this. they can basically trace the history of the virus. they traced this back, i think it was they called it the zaire outbreak and it seemed to have

disappeared for a while and they don't know where it went and suddenly it popped up again. >> i read that same report. anderson, i think in some ways that is good news. for a time there was a concern that maybe there were multiple almost simultaneous or near simultaneous outbreaks occurring, and that would be cause for concern because i think that would mean that the ebola virus itself, the zaire strain, was more widespread and prevalent than it has been in the past certainly or previously believed. and the fact that they were able to trace it back and it sort of made the contact tracing all that we've been talking about, it actually worked in this case, which is good. you want that to work. but also there was a single origin it appears. and i think when you reflect on that, i think that that is good news in a way as opposed to just thinking in several different places around west africa this sort of sprung up, you know, near simultaneously. >> well, dr. fauci, good luck on this vaccine. appreciate you being on. dr. sanjay gupta as well, thanks. >> you got it, thank you.

well, it's a strange story. a college football player sprains both his ankles jumping from a balcony to a pool to keep his nephew from druining. that's what shaw told his coach. it sounds like a great story. it turns out it was all a lie. he confessed and is benched indefinitely.

how did he sprain his ankles? >> reporter: josh shaw was already considered a leader on the field. now he was suddenly a hero off of it. just days ago, shaw said he rescued his 7-year-old nephew from drowning, forced to jump from a second floor balcony to get to the boy in time. in the process, he injured both ankles after hitting the concrete. he told the university website, "i would do it again for whatever kid it was. it did not have to be my nephew," shaw told usc's website. "my ankles really hurt, but i'm lucky to be surrounded by the best trainers and doctors in the world. i am taking my rehab one day at a time, and i hope to be back on the field as soon as possible." and who would doubt him? >> although i play in front of 90,000 fans in the coliseum, i am much more nervous today than any game ever. >> reporter: shaw was a highly regarded student at usc. in may, the trojans starting quarterback was asked to give this commencement speech to his fellow graduates.

he was also chosen as team captain for his final year. >> when i was first asked to be a speaker at today's commencement ceremony, i was truly humbled, honored and overwhelmed with joy. >> reporter: but questions started surfacing this week about shaw's story about his nephew. head coach steve sarkisian was pressed for clarification. >> it's pretty clear there is quite a bit -- there is quite a few conflicting stories out there. you know, any information that we've been provided up into this point, we've pushed along to campus authorities. we're really going to let it play out in their hands up into this point. and quite honestly, we're in somewhat of a holding pattern 10679 that's where we're at. >> reporter: then late yesterday, there was a statement released through his attorney. on saturday, august 23rd, 2014, i injured myself in a fall. i made up a story about this fall that was untrue. i was wrong to not tell the truth. i apologize to usc for this action on my part. while shaw admitted his story was lie, the los angeles police

department tells us there was a burglary at the apartment complex where shaw's girlfriend lives, and they say they have interviewed his girlfriend, but shaw is not a suspect in the case. >> obviously, we thought very highly of him. he spoke at our commencement this past spring. so when we came to the story with us, i didn't have a reason not to believe this guy. so i think that's where the level of disappointment kicks in. >> reporter: a disappointment with significant repercussions. shaw has been suspended from the team indefinitely. sara sidner, cnn, los angeles. >> i want to look deeper why people lie and how they lie. i spoke to professor dan arieli, author of "the honest truth about dishonesty." >> what do you make of this. he didn't make up any lie, he made up a lie of saving his drowning 7-year-old nephew. >> that's a good story. so here is how i view it. you know, i haven't talked to him and i don't know the story in great details. but if try to generalize what is going on, i would say there are three elements here.

the first element is what we think about gains versus losses. the second one has to do with self-deception. and the third has to do with how our lies impact other people. >> in this case, he injured his ankles, and he was going to be out probably for the season. and so he had to come up with an explanation, i assume, for why he was not going to be able to play football. >> that's right. so it wasn't that here was a guy who wanted to become a hero, and he kept on thinking. by the way, it's not a very thoughtful lie. if you really wanted to plan something, he should have thought about it better. but he came up with something spur of the moment to protect himself. he probably wanted to basically portray something that would not make people think he is stupid, and therefore losing this valuable player for no good reason. the second reason has to do with self-deception. self-deception is pass night. it's about our ability to convince ourselves that we have done something that we haven't done. and we all have this capacity. and it's really amazing.

>> it's really fascinating. dan, thank you so much for being on. fascinating stuff. >> as always, pleasure to be here. >> that does it for us. thanks for watching this extended edition of "360." "cnn tonight" with don lemon starts now. good evening. this is "cnn tonight." i'm don lemon. tonight president obama says let's not get ahead of ourselves on isis air strikes in syria. >> i don't want to put the cart before the horse. we don't have a strategy yet. >> meanwhile, syrian opposition groups say they have killed another american in battle, a minnesota man. and tonight i'm going to talk with a friend of his family and to a former jihadist. plus, hillary clinton speaks out, calming the case of the 9-year-old girl who accidentally shot her instructor at a gun range heartbreaking and horrifying. we'll get into all of that tonight. but first, cnn's alexandra field live outside mount sinai hospital where we have just received word on joan rivers' condition. the
