sports team has been honored. it reportedly cost about $2 million. congratulations to the women's team. make sure to follow me on twitter, and also. that's it for "the lead." i'm turning you over to brianna keilar who is filling in for wolf blitzer in "the situation room." have a great weekend. \s. happening now, gun check failure on the day the confederate flag comes down the fbi add mitts making a mistake that allowed the charleston church gunman to purchase the weapon. we'll be speaking with nikki haley. terror pilots? a chilling report suggests two pilots may have become radicalized. the terror group has captured planes. is it now looking for trained pilots to fly them? >> dang are you allyian, a top u.s. general calls russia the greatest threat to america, that as vladimir putin growing closer

to iran is that threat growing larger? i'd ask ed royce. and playing dangerous. would would an airline pilot flush live ammunition down the toilet during an international flight? wolf blitzer is off. i'm brianna keilar, you're in "the situation room." we begin with today's shocking add manages from the fbi. the bureau made a mistake, a big one that allowed dylann roof to buy the gun that he used in the massacre that killed nine people. the news broke on the same day that south carolina tonight down the confederate flag and removed its flagpole a direct result of those shootings, our correspondents experts and guests are standing by to bring you the latest on all you this news.

pamela what happened here? man who confessed to gunning down nine people should never have been able to buy that that .45-caliber gun to kill them. that bomb shill coming from fbi director comey, that a mistake was made a mistake he calls of hardbreaking importance that rips all of our hards out. direct orr comey says when he was arrested in late march. that discovery would have prevented roof from passing the background check. director comey is the the fbi examiner failed for make contact with the columbia police department which arrested roof on that felony drug charge so essentially the examiner contacted the wrong department in part because the clerical error in the system listing the wrong law enforcement agency. after the three-day waitic period the south carolina gun

shot legally used its discretion to sell roof that gun even though his status was still pending. they promised to work on fixing the system. important to know the fbi's revelation today contradicts earlier assertions that the background check was done properly. you can tell he was incredibly disappointed. >> the exercise -- the due diligence -- why did it take so long? >> that's going to be a very big question. i think director comey will face pressure to answer in the next few weeks, brianna. i'm told that agents on the ground knew within days and i'm

told about a week after the shooting. they issued a denial. >> a week after the gun had been performed? >> the gun was purchased much earlier. they realized this is something they needed to check out. so the question is why did it take only until today to make this public? >> we asked director comey that question. he said he came to this conclusion last night. is is. >> this is a huge mistake. it just is sort of obvious that there's a columbia -- this is a state capital. if they're totaln form this is

the columbia police department, but it's not in the phone list i mean i could google that and find it out, right? >> i think what this points to really is a patchwork of gun background check systems around the country. i think we have a map around the country with 36 states that relies on the fbi to do them. and what the fbi has to deal with is simply the fact that you have some court systems that are antiquated and their data does not get updated quickly. >> the fbi faxes the requests in. >> that's stuck in the 1980. >> exactly. it's antiquated, and then they get about 30,000 transaction requests a day. so are there enough people to do the due diligence? >> it seems like there's an

issue with some of the getting to the fbi in such a way that it forces the fbi examinering to the only backstop on making these calls when someone trying to purchase -- >> and they have 72 hours to act. what happened here hat a lot more -- >> this reveal -- >> that's key. it's an incredible thing that happens all the time. and then reveals this person should not have had a gun, then they have to rely on the atf to go retreat the gun. >> thank you so much. >> a chilling new report suggesting that two commercial pilots may have been become radicalized, with one said to have posted pro-isis messages online. brian todd has been dig digging into this.

>> australian employees have potential concerns. that is according to an intelligence report purportedly by the australian federal police. the report says both appear to be influenced by pro-i.s. elements. it was produced by intercept and kiss one of the pilots began to post pro-isis messages on social media, and later listed his current city as raqqa, syria. it's not clear if that peet ever actually traveled to syria a u.s. counter-terrorism official tells cnn that they have specifically called for skilled people to join their caliphate. there's no evidence that they

recruited either of these two pilots. with you pilot is it denies any ties. both of them reportedly no longer work for airlines. their investigation shows the two pilots are not directly involved with isis but he also said they do often post about isis on facebook, and they are sympathizers. the australian federal police tells cnn they don't comment on intelligence matters. >> i think the issue here is the vulnerable that's raised here right? the fear about what a trained commercial pilot with terrorist leanings can do. >> that's right. an analyst told us today that commercial pilots have intimate notion of the aircraft of course but they also know about security procedures.

they've been trained on the verbal coats to use. they know what to say to controllers if something nefarious is happening. they know all about evading radar detection. you can imagine a full-fledged isis member or follower with those skills piloting a commercial plane with hundreds of people on board if it ever came to that. again, we have no evidence that these two are at that level. they are simply sympathizers according to the indonesian police chief, but it's the potential for what could happen here and the skills that one could bring that really is snee cheering. >> hard-line protester back home chant death to america, iran's negotiators are still trying to work out a nuclear deal. they're making progress but it's not enough. there's serious sticking points and the talks have been extended yet again. elise labott when have these talks been extended to?

there vin intense last few days. yet secretary kerry came out with a very tough message, in fact, take this deal or leave it. but today the storm seems to have passed. they talked about some progress in the talks. take a listen. >> we'll be sitting down to discuss those in the very near term. this evening into tomorrow. but i -- i think we have resolved some of the things that were outstanding, and we've made some progress. >> they're going to work through the weekend, as he said but very key sticking points and it's very tedious work brianna. i think 100-page documents they're pouring over every word.

i think they have a few intention days. >> i know a lot, as we go into extra innings here. what is the prognosis here on there being a deal? >> i think they're more optimistic make more realistic chances. they do have a couple key sticking points. we're not just talking about numbers here we're talking about fundamental political decision that maybe the supreme leader has to take but can the iranancy get to yet? if they had, there's going to be another couple difficult days ahead of them brianna. >> a big couple days. elise, thank you very much. joining mess republican congressman ed royce of california. congressman, thanks so much for being with me.

first i want to talk about the breaking news from the fbi about dylann roof the shooter at mother emanuel church who is charged with killing nine people. we've learned from the fbi, saying they made a mistake, he should not having able to get this weapon. he admitted he had possession of drugs, and that would have been a disqualifying factor for him in purchasing the gun. that specific info didn't get to the fbi. they knew something was you said they should have closed the loop on it, they didn't. >> generally speak, how did this happen? >> the way in which it happened and i support criminal background checks. the way in which this happened one city was in two cowards, so you had a situation when the fbi accessed the data. it was a mistake. but clearly we need to put more resources into the fbi, so that they can update this system and make sure that glitches like

this in the future do not create this kind of heartbreaking result. >> should expect there's more than one city in the county? there was west columbia but the actual information said it's columbia -- our columbia police department has the information on this guy. there was only a number for west columbia. the examiner called west columbia. this is a state capital, not some obscure city in south carolina. is it a matter of that examiner being overwlaumd? they're getting a lot of requests? what do you think? >> i think she worked on about 14 cases that day. >> really? wow. >> so she did have quite a few requests to deal with. so part of this is going back through the database to make sure we have -- who need to

access this information on a daily basis, to make certain that mistake are not made in the future. and more resources, frankly for the system. >> there's a 72-hour window for the fbi once a gun applications goes through for them to respond. do you know what point this examiner was calling? >> i do not know but you and i now know the totality of this and that had everything gone right, there is no question that he could not have gotten the ability to buy that .45-caliber. that is what's so terrible about this. that's why i think there would be a lot of changes in looking on how to make certain something like this doesn't happen again. >> stay with me. we have much more to talk about. >> we'll be right back with chairman ed royce after a quick break.

how foreign affairs chairman congressman ed royce of california with me right now, but first even as top u.s. general -- as a top u.s. general calls russia the greatest threat to u.s. national security.

>> reporter: because that general maze those comments the state department moving to try to make sure that russia doesn't get too irritated at the pentagon. >> the just watching carefully, a very friendly handshake between russian president vladimir putin and iranian president rouhani, just one symbol of what the u.s. increasingly sees as a dangerous alliance. >> one country that could pose an existential state, it's russia. if you look at the behavior it's nothing short of alarming. >> reporter: the threat between the general who would become president obama's top military adviser in a few weeks, and the secretary of state. >> secretary doesn't agree with the assessment that russia is an existential threat to the united states. >> but listen to vladimir putin press for iran's desire.

>> we think iran should have sanctioned remove. s question be in what period of time and how quickly. >> reporter: russia has already lifted a ban on the sale of a sophisticated air defense system to iran. a russian weapon that could shield iran's nuclear facilities from future air strikes. >> this also jet aircraft armored tanks armored personnel carriers artilleries, trucks these are the kind of weapons that could fuel a middle east arms race. >> and tehran may soon have a lot more money in its pockets. >> there's no question that if you lift these embargoes now and at the same time are giving iran access to some of the its frozen billions of dollars iran will be able to accelerate its missile program. >> the current joint chiefs chairman leaves no question where he stands.

>> under no circumstances should we relieve fresh. and orange traffic. inch the pentagon sticking to its guns. says russia is also developing new conventional cruise missiles. if they deploy those, it would be much hard ser for him. >> thank so much. we're back now with the chairman of the house foreign affairs committee, republican consequenceman ed royce of california. consequenceman we heard general dunford saying this week that russia quote, presents russia presents the greatest threat to our national security. do you agree with that assessment? >> if you look at what he's saying the reason that russia presents a threat is because of the russia's cooperation with iran. i would take that one step further.

i would say iran right now presents long term the greatest threat. russia is insisting iran but if you listen to the ayatollah he says several things. every military man should figure out how to help produce icbms, blis ig missiles that can reach the united states. he speak toss that issue, and they he leads people in a chant of death to america and death to israel. this assistance that so far we've seen russia give to iran has helped iran in its offensive capabilities and this is or concern in terms of our national security interests. >> what should the u.s. do? >> for one thing, i think in these negotiation, we have to make absolutely certain that inspectors have the right to go anywhere any time in iran to look at the nuclear program, including on military bases. that's where we've found them testing their bomb work before.

russia has not been all that supportive in that but we need to insist upon this. second we should not give a signing bonus to iran of $150 billion until we are certain -- certain that they're not moving forward with a nuclear program. we need to phase that in. if we give that money up front, they're going to buy more missile systems from russia. that's russia's financial interest in this. >> it seems like iran has been trying to throw a wrench in the works here saying you know this u.n. embargo on arms should be lifted basically we should be able to buy weapons. that would be big money for russia advisories is there really any possibility that the u.s. would agree to that? >> i don't know it would be a mistake to do it because a few weeks ago, it was announced that iran was sending into gaza new missiles to replace the ones

that were already launched in the last gaza war and rebuilding the tunnels, and in addition there's 100,000 rockets in hezbollah's possession under iran's control. they now say they're going to send precision guidance systems, so that those missiles can be prepared to hit different targets within israel. that will open up all of israel to a potential attack. so this kind of aggressive behavior by iran demands on our part that we hold the line we keep the sanctions in place, that have some impact on keeping the conduct in check, and that we not let up on an agreement that would allow iran to develop nuclear weapons capability like north korea did, without the inspections, so this takes on new significance. >> thank you for the insight. coming up a new embarrassment involving planes and guns. why did an airline pilot flush

we want to get back to the record that two commercial pilots may have become radicalized, inspired by isis. joining me now, we have cnn counter-terrorism analyst phil mudd. we have cnn law enforcement analyst tom fuentes, the former fbi assistant director and cnn intelligence and security

analyst bob baer. phil i want to check in with you about this report bakley the airlines pilots were posting sympathetic communication -- not -- sympathetic messages online for some time sympathetic to isis and then it appears one popped up in raqqa, syria. which of course is a hotbed for isis. could isis be trying to recruit pilots? >> sure. there's a couple ways i would be thinking about. we've seen a large geographic expansion, and forget about air planes wharks about tanks armored personnel carriers. the iraqi military fell apart years ago, so isis presumably has people in the ranks who have been operating some equipment. ivan seen self-recruitment by al qaeda, people mailing in saying i want to participate in jihad, will you allow me to join the fight. the most worrisome was a guy

self-recruiting out of an airport, that was years ago. >> someone who is through security who as -- >> who's writing in. i would say isis has more of an opportunity to do that. in contrast to al qaeda, they are way out there in social media, trying to find people -- >> we know this was a facebook post that one of these pilots posted saying he was in raqqa. we don't know if that is for sure. certainly if it's confirmed, that's very alarming. bob, isis has this rule after establishing this caliphate, they are supposed to be essentially nation building in a way. it makes sense they might be looking for recruits with certain skill sets. what are they looking for? >> well i mean they do have a nation. they have a capital, a military force, which is taking ground. they are providing services and they are trying to establish themselves to remain in existence for a very long time.

right now what they're mainly looking for is money. they want to get to the gulf they have emissaries out there, get as much money as they can. they also need logistics. >> they also need -- go on sorry, bob. >> yeah they need logistics, all sorts of equipment, they need people with specialties. for instance encrypting. any number -- medical, doctors, they've been recruiting a lot of doctors as well as airline pilots. >> you know for sure they've been recruiting airline pilots? or is this just appears to be something that could be happening? >> it appears to be but it fits within the pattern that they are finding -- people with technologically savvy. >> so it makes sense, tom, but we don't know for sure if this is happening. this is what i wonder about. we look at the timeline for when

these guys start posting messages sympathetic for isis. a lot of time passes before one says essentially i'm in raqqa. if this happened in the u.s. if you had pilots or even other people with skill sets that would be valuable to isis how much time would it take for u.s. intelligence and law enforcement authorities to track those guys down? >> it would take a short period of time to start the investigation. >> to monitor them. >> see what they're up to but this shouldn't be any great surprise. we had colonel hassan a high-ranked trusted officer radicalized by al qaeda in yemen, and kill more than a dozen soldiers at ft. hood. and it isn't as extensive or successful as isis. if that could happen from al qaeda -- not only that, we're talking about who eye says is trying to recruit.

what about the pilot who tries to join. not everything that want to join them is a loser is downtrodden. we have doctors, lawyers, senior officials, executives. people in all walks of life who admire isis and may even go over the edge. thank you so much. next after watching the confederate flag come down thoughts are shared with don lemon. a bisas indent frightens passengers and may cost a pilot his job. ♪ i'm the biggest threat your business will ever face. your size, your reputation mean nothing. because tomorrow, i'll be your competitor. and i was born to disrupt everything

she was very personal about why she felt this flag should come down. >> so governor you will remember where you were on july 10th 2015 you presided over history. what does that mean to you? >> you know, this is a surreal moment. standing out there watching that flag come down it felt like the biggest weight was lifted off the state. it just felt so -- it's like the state -- it's a true new day in south carolina. it feels like a new day in south carolina. >> you have said this i don't know if it's in the exact words. you weren't always on the side of taking this down but i think it takes a big person to change their mind. >> it wasn't that i wasn't for taking it down. first of all south carolina very much respects history, respects tradition, so the flag has just always been up there. when i came into office to have a two thirds vote threshold was a huge one. it's not a republican/democrat,

white/black, there hadn't been a billed filed to bring it down since 2007. there was so much of a divide and so much hurt in the compromise of 2000 that no one wanted to talk about it. so it was almost like people just assumed it was going to be there. >> you've used the words in the signing of this bill you said tradition, you said history, you said respect, love and forgiveness. it has to have been hard to strike a balance, because not everyone was on the side that you were on. >> it's important for people to know what it's like to be in another person's shoes. if you watch the legislative debate that's what happened. people put themselves in each other's shoes, so they understood what the respect of tradition and heritage was, and that it wasn't about hate. but the other side also learned how painful that flag was and the pain in a it was causing people. that's what brought south carolina to this new day, was the able to look at each and

listen and say it's time. >> you're an immigrant, your family -- you grew up here. >> born and raised of south carolina, but the daughter of indians parents. >> does it mean more to you, more connect to do this issue? do you have a special feeling about it? >> we grew up an indians family in a small town of south carolina. my father wearing a turban. my father at the time wore a seari. it was hard growing up in south carolina but i worked hard to make sure my kids don't go through what we went through. now i know my kids can look up and there window be a flag and it would be one less reason to divide and there will be more reasons for us to come together. >> now, as i understand you went up and looked over at the flag this morning and it was important for you to do that. why? >> i just needed to see it one last time. i wanted to remember the moment. you know so much of this has a whirlwind over the last several

weeks, extremely emotional, but i just needed to see what was about to happen. >> this flag went up in 1962 correct? do you think it was sort of a poke in the eye to the civil rights movement? >> you know i'm not going to try to figure out why people did what they did. i think the more important part is that it just never should have been there. i think that even when it was on the grounds of the statehouse it was right in front. these grounds are a place that everybody should feel a part of. these grounds are a place that belong to the people of south carolina. what i realize now more than ever is people were driving by and they felt hurt and pain. no one should feel pain. you know we can have our disagreements and we can have our policy back and forth, but no one should feel pain over something, not over a symbol. >> so there was a lot of pain but also a lot of pride. you know some people see this as a symbol of pride for their

ancestors. she had to walk a political tightrope to get this to come down. >> she was sort of offering an olive branch to those people in hour fascinating comments in this interview. did she talk about the future of where she goes from here? so many people have said this is a significant step but this is just one step in this journey. >> reporter: she did. i think she said the way to honor the nine people she died what she plans to do is carry on some of the work of clementa pinkney, who was a state representative and who also died in that church. she believes the best way to do that is carry on his legacy of education, but also in the interview she talked about speaking of race she said that would be part of her platform to brings people together at least when it comes to race relations in this state. >> don, stay with us, we're going to be talking with you more coming up in just a moment.

why would an airline pilot flush live ammunition down his plane's toilet? new details about this frightening and bizarre incident. renee marsh is with us in "the situation room."

>> briane na, i wan tell you this united airlines captain flying an international flight is now under the microscope of federal investigators because of prohibited items he brought on board in his suitcase. a bizarre incident caused panic among some passengers on board a united flight from houston to munich. tonight it could cost the pilot in civil penalties. sources tell cnn it all began when the captain, who the airline is not naming realized he was carrying live ammunition in his suitcase. something not allowed on international flights? >> very restrictive. i'm sure the pilot realized at some point he would not be able to get into germany with ammunition in his carry-on. >> reporter: the captain threw the bullets in the trash can of the boeing 767. a passenger looking for a missing ring discovered them and alerted a flight attendant, who

called the captain. fearful he might get in trouble, sources say the pilot took the bullets and flushed them. >> it absolutely could have caused a panic in flight at least amongst the crew in the cockpit. fortunately the pilot stepped up to the plate and admitted that he had thrown the ammunition in the trash. had he not done that, that would have caused all other kinds of bells and whistles to go into play. >> reporter: tonight, united says it is reviewing the incident but that the pilot remains an employee. meantime the tsa says it's reviewing if the veteran captain should face self penalties. the captain did not have a gun. just the ammo. but there are instances when it's okay for a pilot to be armed, after september 11th an extra layer of security was added allowing pilots and flight crew who are trained by tsa to have guns on board u.s. flights only to defend against hijackers and terrorists. they're still not allowed to

take ammo and guns on board international flights, brianna. >> renee marsh, thank is so much for that report. i want to get insight with former fbi drift ant director tom fuentes. flushing bullets down the toilet. let's take this one step at a time. there's different parts of this that may or may not be dangerous. is that dangerous? >> i don't know. i don't think so. i think the bullets are waterproof and unless something strikes the primer to cause the bullet to go off, and i don't think necessarily would happen in the disposal system -- so i don't think in and of itself it's dangerous other than somewhat maybe being discovered later on and launching a terrorism investigation. >> sure. >> in germany. because, where did this come from? if there's bullets, where are the guns? >> throwing bullets away in the trash can of an airline restroom is that dangerous? >> someone found them and turned them in. in and of itself from the standpoint of bullets going off

by themselves, no not necessarily that dangerous. but what would happen when people find them and when the crew sees this and when the authorities in germany, when the plane lands, sure all the bells and whistles are going to go off in terms of warnings and alerts and investigations. the captain did the right thing, turning himself in. i don't think he did the right thing throwing them in the trash in the first place. he should have kept them in a container in the cockpit, immediately contacted security or have united while he's in flight say here's what yiti did, have security meet me it was an accident an oversight -- >> the cover-up may be worse than the crime if this was him trying to make it so his bullets are not discovered. tell us how often this happens, domestic flights, this idea that you can have a pilot carrying a gun on a plane here in the u.s.? >> when i was in the fbi it was mandatory for us to be armed on all domestic flights. the captain would let us know if he was armed.

they were occasionally armed and had authorization to be armed in the cockpit so they're out there. >> that you can so much tom fuentes, appreciate it. on the day that the confederate flag comes down the fbi admits making a mistake. a huge mistake that allowed the charleston church shooter to purchase his gun when he should not have been able to. could a better background check have prevented this massacre? a chilling new report suggests two commercial pilots may have become radicalized, inspired by isis. the terror group has captured planes. is it now looking for trained pilots to fly them? got the card, hon? yep. as a member of aarp... the discounts are right there with you. like roadside assistance from allstate... all set! and expedia vacations. aloha!
