invading ukraine. according to nato and many others. and this has been the worst week of the worst ebola outbreak ever. u.s. health officials preparing to test a vaccine in the united states as we witness the biggest weekly jump in cases yet. good afternoon, everyone. welcome to "the lead." i'm jake tapper. we begin of course, with the world lead. 35 million americans will be traveling this labor day weekend, according to aaa. that's the highest number in six years. so pack the kids in the car or board your flight or take your seat on the train. don't worry too much about terrorists from isis committing an atrosity on u.s. soil according to the fbi and department of homeland security who are, they say, unaware of "any specific credible threat to the united states homeland from isis." this is despite the british government raising the alarm about isis within its own borders. let's get to our pentagon correspondent barbara starr. what exactly are the british saying? >> this is the issue on this holiday weekend. the question, why is london so worried and washington is not? two leaders with very different public messages on isis. british prime minister david cameron announcing the threat level is raised to severe in the uk. >> this is not some foreign conflict thousands of miles from home that we can hope to ignore. >> i don't want to put the cart before the horse. we don't have a strategy yet. >> president obama not ready to commit to fighting isis with air strikes in syria. but britain clearly feeling the pressure that isis could strike it at home. the new warning means an attack is highly likely. >> the ambition to create an extremist caliphate in the heart of iraq and syria is a threat to our own security here in the uk. >> particularly worried because it was a british voice on the tape showing the murder of american journalist james foley. an estimated 500 people have traveled from britain to fight in syria and iraq along with hundreds of other europeans. u.s. and european security services believe isis fighters are back at several locations in europe, but those cells may not be under direct isis orders. officials won't say where the cells are. u.s. officials say they don't believe there's a cell in this country, but are tracking about a dozen americans fighting for isis overseas. just this week, two american isis fighters were believed killed in syria. >> i think our european allies feel a greater sense of urgency. i think they feel as if the threat is closer to home right now and for us, it's more of a distant issue. >> for now, the u.s. plans no changes. the department of homeland security says it's unaware of any specific credible threat from isis. some analysts say, however, this is not the time to sit around and wait for what may be an inevitable attack. >> we need to understand that this is a threat now to our homeland. and we have to start designing a game plan to defeat them as quickly as possible. >> counter-terrorism officials will tell you one of their biggest worries in all of this in the united states is some isis loyalists is takening essentially a lone wolf attack. it's one of the toughest threats to detect. jake? >> barbara starr at the pentagon, thank you so much. the united states and the united kingdom are an ocean away but air travel makes the whole world feel a lot smaller. it would only take seven hours to leave london where an attack is according to the government highly likely and arrive in the u.s. where authorities are unaware of any specific threat. rene marsh, when we're going through airports this weekend, will we see increased security? >> you will. but the tsa is saying that's a function of it being a busy holiday travel weekend, not because there's a specific threat. that said, they are doing more. the u.s. tells cnn they are actively tracking known foreign fighter who's travel in and out of syria, but the problem is the unknown fighters. it's an unsettling mix, terror threats during a busy travel holiday. the uk's they're the level raced to severe for fear westerners fighting for isis overseas could fly back home, and the u.s. department of homeland security said it has enhanced security overseas at airports with direct flights to the u.s. but no change so far in the terror alert system. >> i don't anticipate at this point that there are -- that there's a plan to change that level. >> this summer, following intelligence, terrorists were developing more sophisticated bombs designed to avoid airport screening, flyers from middle east and european airports bound for the united states have had to power up all electronic devices to prove they weren't explosives. governments are on high alert for foreign fighters looking to return to their home countries. >> we are stopping suspects from traveling by seizing passports, we're barring foreign nationals from re-entering the uk, depriving people of citizenship. >> the u.s. is striking a similar tone after two americans were killed fighting for isis in syria this week. >> we have the prerogative at the state department in coordination with law enforcement authorities to revoke passports when it comes to a point where somebody is working with a terrorist organization or posing a threat to the american public. >> the government's no fly list and law enforcement watch lists are updated and sent to tsa in realtime as threats develop, but it's not a perfect system. >> when i went back to florida. >> muhumed abu salha grew up in florida, he flew to syria, trained as a jihadist, then returned to the u.s. he was able to fly again overseas, not to be seen again until -- he blew himself up in a suicide attacking in syria. >> we know something about somebody. they're going to be questioned. the real concern is the sleeper cell, somebody that hasn't -- they're under the radar. >> the 14 million americans taking to the sky this weekend may see heightened security already in place because of the busy labor day travel. but moral security is being considered and not all of it will be visible. well, the u.s. no longer uses a color coded terrorism threat system. they stopped that in 2011 because it was confusing and ineffective. the system used now posts alert on the dhs website and sends it out to both the press and social media when there is an elevated threat. >> i'm glad you included the bit about the florida jihadi. it raises questions how much the u.s. government knows who's coming and going. thank you so much. the u.s. military today announced carried out four more air strikes on isis targets in iraq but when it comes to dealing with isis in syria as you heard a few moments ago in in barbara's report, president obama said "we don't have a strategy yet." the president is taking a lot of heat for his phrasing on that. so at today's briefing jim acosta asked the press secretary whether the president would care for a do-over. >> does he wish he had articulated that sentiment differently? >> he was asked a very specific question whether or not the president would seek a congressional authorization before ordering any sort of military action in syria. >> the president hasn't yet laid out a specific plan for military action in syria. and the reason for that is simply that the pentagon is still developing that plan. >> jim acosta is joins us now live from the white house. jim, you gave the white house a chance to try and unring that bell about saying that they lack a strategy. they didn't take it. >> that's right, jake. no apologies from the white house for what the president had say yesterday. when i asked josh earnest about that, that comment from the president, when it comes to launching air strikes in syria, josh said it was the media's fault, that members of the media misinterpreted what the president said. that's the reason why the press secretary went out and did all the interviews with a variety of cable outlets including cnn. he was first on cnn trying to explain that about an hour after the rez wrapped up his remarks. josh went on to say and you heard in that clip you just played, that the reason why the president said there is not a strategy for hitting isisle? syria is because the military hasn't developed any plans for that. over at the pentagon today, the pentagon press secretary was asked about pentagon planning for isis in syria and he said "i think anybody who has any knowledge of the united states military knows that we're ready. so there's a bit of a disconnect there in terms of what the pentagon has developed in terms of planning for air strikes in syria and all of that raises the question, jake, as to whether or not there's a debate really going on inside the administration between the white house and the pentagon. i asked josh ernest about that. he went on to say, he wouldn't characterize it as a debate. he didn't deny there's a debate but he said when i asked if the president is on the same page as his cabinet, he said that the cabinet is on the same page as the president. so if there was a debate up until yesterday, white house press secretary is trying to say there isn't one anymore. >> thank you so much. we have more on the president's leadership and those comments later in the show. coming up next, what's scary enough to make the brits raise their terror threat level? we'll try to pin it down. plus an organization that can dig into your e-mails has a covert drone program. i'm not talking about the u.s. government. spy thriller? you don't know "aarp" thanks to the aarp tek program, this guy is spying on his new grandson. aarp tek gets people better connected to technology, to better connect with each other. with social media, digital devices and apps. if you don't think "hashtag love dad" when you think aarp, then you don't know "aarp" find more surprising possibilities and get to know us at aarp.org/possibilities it's time to bring it out in the open. it's time to drop your pants for underwareness, a cause to support the over 65 million people who may need depend underwear. show them they're not alone and show off a pair of depend. because wearing a different kind of underwear, is no big deal. join us. support the cause and get a free sample of depend at underwareness.com for over 19 million people.

orange, red, the united states has long retired our rainbow of fear terror threat alert system bourn out of 9/11. but today the united kingdom is bumping up their threat alert level from substantial to severe, a rating means a domestic terror attack is "highly likely." let's bring in paul kruk shank and cia official now co-founder of the chart to have of group, a global security and risk management advisory firm. chad, let's start with the basics here. what has prime minister cameron so concerned here? >> it's clear they have intelligence indicating a direct and imminent threat. he is leaning forward airing on the side of caution. he wouldn't do it lightly. it's very disruptive to do that. at the end of the day, i think he's he erring on the side of caution. >> paul, would it need to be specific intelligence or just enough of what they know, british accent of the guy in that horrific james foley video, the fact they know that will 500 or so british citizens have fought in syria, some with isis? is that enough on its face? >> i don't think there's a specific threat stream here or a specific plot they're looking at. it's more a confluence of different factors. the biggest one are the u.s. air strikes in iraq against isis. the fear this could be retaliation against the united states, a strong ally of the united states. next week, there's a nato summit in wales, the largest gathering ever in the uk. it's not lost on british security officials the last time there was a major terrorist attack on british soil, there was a g-8 summit. >> the how hard is to monitor -- a lot of people, myself among them, don't understand how there are all these surveillance and monitoring systems and yet, as we saw in the previous segment, you have that florida jihadi. he fights for syria, flies back, visits florida, goes back, does a terrorist attack. he was with al nusra front which is with al qaeda, still a horrific organization. why don't we know, i know you're not in charge anymore not specifically for this guy, but why don't we know more who these people are coming and going? >> that's a great question. in the world of 24 or ham land," post snowden, citizens expect we're tracking things all the time. we did plymouth biometric fingerprint capture. every foreigner coming and out of the united states has to have a finger trip. for foreigners is we can track those movements. the thing so concerning about this scenario or u.s. citizens in particular, that the the hole that the current system can't do other than just through good old fashioned and human traffic traveling >> there's concern some of these brits could get on a plane to the united states and try and launch an attack. here we saw back in 2006 a transatlantic airline plot, that was an al qaeda plot where they were targeting ten planes. they were planning to get on planes from the uk to come over to the united states. they don't need visas to do that. >> if you're british, you don't need a visa to come to the united states. >> you do have to get fingerprint capture for your first trip. and then the key thing i would flag is what paul said. at the end of the day, this administration said they're not going to elevate here because the thread over there is increment lit greaterer, 500 or so brits estimated. the dilemma is all it takes is one. they're one plane ticket away from an attack on the united states. in this case, especially after the misstep yesterday on the president's comments regard no strategy, you would think they might want to lean forward the way prime minister cameron has done and there's significant risks to the president if one individual does carry out an attack between now and then. >> paul, foreign policy magazine is reporting on an isis labtop discovered with the jid hattist justification for chemical weapons, information about certain biological weapons. even if they do not yet have weapons of mass destruction, isis and they don't seem to, how close are they? including biological and chemical weapons. >> one thing aspiring to want to do this, researching this, but quite another operationalizing it, the distribution systems for this kind of attack would be very, very difficult. al qaeda has been trying for 20 years and never got close. the warriors with isis they now have a control of a lot of territory, cash rich, all the recruits from the middle southeast some of whom have a scientific background and they control cities, al qaeda in afghanistan far away from civilizati civilization. >> as somebody who worked for the department of homeland security, why the can't the united states succeed in getting more action from our arab allies to go after isis? it seems like the president obama talked about trying to get sunni allies. john kerry will go on a mission to do that. it's in their interests they don't want the islamic state existing in that part of the world. >> you're going to see a stepup of cooperation and collaboration. it is a common threat. the only issue is that the region is complex. there are different factions both within the isis itself, but also religious, the sunnis versus shiites. that's something to watch out for. at the end of the day, it's going to take a whole government approach and the united states has to lead the effort. >> where are they getting their money from? is it because they control some of the oil fields? >> that's one of the major revenue streams for them. they burn through cash very, very quickly with all their operations. the warriors have tens of millions of cash reserves. the 9/11 operation cost half a million dollars. >> terrifying. pull kruk shank and chad sweet, thank you so much. coming up, the only thing bolder than russia's invasion of ukraine may be russia's denial of russia's invasion of ukraine. as many as 5,000 troops flooding over ukraine's border. there are photographs to prove it. plus, it's been the worse week of the worse

fast visual confirmation from nato in the form of this satellite imagery of russian troops in ukraine, in total as many as 5,000 according to british officials, well, russia still says nyet, they have not invaded and have no involvement in a battle that has now cost more than 2,000 lives. diana magnay is in the strategic seaport in the ukraine. if you believe any of that, i have a bridge to sell you in st. petersburg, of course. how long can putin's denials go on? >> how long is a piece of string, jake? vladimir putin is a master of denials and obfuscation and the west is pretty much come to expect nothing more from him. but they don't seem to have been able to come up with any kind of effective policy response to make him change his course because sanctions certainly don't seem to be making him change course. i think that's partly because no one can quite work out what his end game in east ukraine actually is. >> president putin also compared the ukrainian troops to the nazis who stormed leningrad in world war ii. does that is work? does that kind of propaganda invoking their heroic efforts against the nazis on the russian population, on the russian cran public? >> well, for those who watch russian state media over here and certainly for those, the majority of russian household who's watch russian state media in russia itself, the sort of positioning that president putin puts himself as the guardian angel really are of russian speaker and of the innocent in this conflict is a message that they firmly believe. he controls the state media. he can say what he likes. when you go to moscow and talk to certainly those who still support the rebels on this side of the russian ukrainian border, they do believe that that line although to the rest of us, when you start hearing nazi analogies to compare with president poroshenko's policies in donetsk and lohansk, it seems an exaggerated claim. >> coming up, we don't know what he is willing to do but we know what he is not willing to do. now even some of his fellow democrats are privately expressing frustration with president obama's response to isis. stay with us. the most amazing things we build and it doesn't

even supporters of president obama seemed caught off guard by his statement yesterday that there is no strategy yet for air strikes targeting isis militants in syria. and regardless of the spin being put on what many describe as a gaffe, today, president obama's words seemed to have bolstered what many critics have been saying all along about the obama administration and its inaction against a growing global threat they're a terror group with big apple bigs. isis has taken cities in iraq and syria and even killed an american citizen. in response today, the united kingdom elevated its terror threat level from substantial to severe. >> we cannot appease this is ideology. we have to confront it at home and abroad. we need a firm security response whether that is action to go after the terrorists, international cooperation on intelligence, and kinds of terrorism or uncompromising measures against terrorists here at home. >> to his critiques, david cameron's announcement today seemed a stark contrast to the message conveyed by president obama thursday when asked about attacking isis in syria. >> i don't want to put the cart before the horse, we don't have a strategy yet. >> critics say those comments seemed hardly reassuring, comments that required his press secretary to engage in some clean-up. >> we do have a comprehensive strategy for dealing with isil. what the president is still waiting on are military options being developed by the professionals at the department of defense. >> to the his critics the comments symbolized their issue with his leadership on the world stage. >> we got so scared off by what happened in vietnam we were unable to use power wisely. now we've got an iraq syndrome where there's reluctance to think comprehensively what power should be brought to bear. >> even some democrats privately say they cannot recall a president who spends so much time announcing what he is not willing to do in the name of protecting the u.s. and its allies. >> we are not taking military action to solve the ukrainian problem. >> this be and a less engaged u.s., the president's critics say, leaves a vacuum, particularly in the middle east. while it's true the u.s. is engaged in humanitarian missions and bombing isis in iraq, the president suggested the goal so far of that mission is not to defeat isis. >> our focus right now is to protect american personnel on the ground in iraq. to protect our embassiy, to protect our consulates. to make sure that critical infrastructure that could adversely affect our personnel is protected. >> and than perceived vacuum can spill over into other areas, as well. >> there is a perception that the u.s. has the capability to deal militarily with the security challenges that seem to be proliferating but that we lack the will. >> most recently, the uae and egypt teamed up to take military action against extremists in libya. convinced the u.s. would not do it, those two countries did not tell the u.s. about their operation. israel and egypt took actions against hamass in gaza without u.s. involvement. russian president vladimir putin has annexed crimea from ukraine and despite his adamant denials, he now seems to determined to grab the rest. the president's defenders see this all quiet differently, pointing out that putin annexed part of georgia during the george w. bush years. >> we don't want to replicate some of the mistakes we made in 2002 and 2003 when we made assumptions we had facts that turned out to be rememberious and then we took military action. we want to be very careful in this. >> joining me is it david rothkopf, editor-at-large of foreign policy magazine. good to see you. what was your reaction to the president's remarks yesterday specifically saying there's no strategy for isiss in syria? >> i was disappointed but i wasn't surprised. we don't seem to have a strategy to deal with most of the issues. the president seems to want to lean away, not get involved, get out of places where we have been involved. and as a result, whether it's ukraine or syria, whether it's iraq, whether it's afghanistan, whether it's libya, we right now are reacting. we're back on our heels. and that's how you end up with statements like the one you ended up with yesterday. >> you wrote something fairly scathing about the administration's handling of the isis threat. "there are no risk-free in initiatives. indeed if this recent plan reveals anything, it is that the search for risk-free options may be among the most dangerous paths to choose of all." so you think that we should have a comprehensive strategy to go after isis and we should be doing it and not just focused on as president obama put it, just trying to protect our folks in northern iraq? this should be a bigger campaign? >> i think that's definitely the case and what's more, i think there's a real opportunity to do that. first of all, the extremist threat isn't just isis. it's hamas. it's al shariia and other groups in libya. it extends right across the globe, boko haram in nigeria. the chinese are worried about it. what that creates is an opportunity to work with those countries that are frightened or concerned by this, whether it's our traditional gulf allies with israel, china, even russia, all share an interest in containing this threat. so this is a moment where the white house can step up, put together a coalition, can use force where force is necessary, but also move forward to creating political alternatives to these groups which is just as important. >> but you saw what happened when a year ago, the president made an effort to get a international coalition to go after assad and that didn't work. i don't know how much willingness there is among other countries, certainly europe is not willing to put its money where its mouth is when it comes 0 sanctions against putin in russia. >> i don't think everybody's going to be willing to step up. you in your int row talked about egypt and the uae taking steps against libya. that's precisely what we asked for. yet, once they took action, the white house perhaps fearing like they were flat footed themselves, criticized them for doing precisely what we wanted. there are plenty of countries willing to step up and help but also there's the issue of leadership. sometimes when the rest of the world doesn't want to go along, the president of the united states is in a unique position to motivate them if he has the will to do so. and what we've not seen from this president in any of these situations is him investing his own political capital in making change happen. that's what people are looking for. that's what we need a president for in situations like this. >> david rothkopf, thank you so much. coming up, an experimental drug might be enough to beat back ebola but can the virus be stopped before it jumps to american shores? and later, google wants amazon to know anything it can do, they'll try to do better. google getting into the delivery drone wars now coming up. where the reward was that what if tnew car smelledit card and the freedom of the open road? a card that gave you that "i'm 16 and just got my first car" feeling. presenting the buypower card from capital one. redeem earnings toward part or even all of a new chevrolet, buick, gmc or cadillac - with no limits. so every time you use it, you're not just shopping for goods. you're shopping for something great. learn more at buypowercard.com exists 150 years of swedish coffee experience. that's 150 years of experience in perfecting the rich, never bitter taste of gevalia. and we do it for this very experience. this very second. this exact moment. that's good. i know right? cheers to that. gevalia. 150 years of rich, never bitter coffee. remind me to tell her happy anniversary.

>> no, i don't think it's been too slow. i think that the situation has really overwhelmed because it's taking place in countries that don't have the infrastructure to be able to deal with it, and the things that you need to contain it, the isolation capability, the contact tracing, the quarantine, the actual equipment personal protective equipment these are things that certainly need now to be escalated up. the effort has to be ratcheted up at a much, much higher level because the situation there is really extremely serious. >> we know that will several experimental drugs are being tested to deal with ebola potentially. how close is the medical community to arriving at something that can be used en masse to combat this outbreak? >> well, i wouldn't say close enough that there's going to be an immediate effect. for example, as you probably heard, the day after labor day, we're going to be putting the first vaccine in an early trial into humans, one that can looed really very good in a monkey model in protecting monkeys from lethal challenge with ebola, but in order to really deploy something like that, you have to show that it's safe first, that it induces the kind of immune response and that ultimately will be eb. this is going to take at a minimum to just show that it's safe enough to give to people a few months. we won't know that till the end of the year and then you can think in terms of maybe doing a clinical trial where you can show the efficacy with regard to drugs for people who are already infected, a lot of these are maybe three or four candidates that are in the preclinical stage meaning they've been shown to be pretty good in animals. they've got to get tested at least minimally to show they're safe and to get the right dose. what we're talking about is a number of candidates that are lined up but they're not going to have an immediate impact. that's why we all in the public health sector emphasize that the way now to try and stop this outbreak, this serious outbreak is by just amplifying and scaling up the public health measures of infection control. that's what we have right now and we've proven in smaller outbreaks that that, would. so although we're working extremely intensively on developing drugs and vaccines, that's not going to do anything in the immediate future. we've got to do the infection control. >> and how likely do you think it is that this it is going to spread beyond africa? >> well, it certainly is feasible as we've already seen over the last several weeks how it's unrolled that neighboring countries are at risk. neighboring countries within that african region. as far as a patient getting to a developed nation that has good health care capabilities, i would not be surprised that someone who got infected in a west african country did not note they were infected, got on a plane and landed in a developed nation, be it the united states or the uk or europe and then got sick in there and may have seen infected a person or a couple of people. but the health care capabilities in those countries jake, are such that it is extraordinarily unlikely that you'll see the explosive outbreak that you're seeing now because there are well tested ways to contain this. if you have the good hospital capabilities, good contact tracing, you can contain it. so i wouldn't want anybody to think you might not have i case or two outside of africa, but it is extremely unlikely that will explode into the outbreak we're seeing now. >> dr. to youchy, thank you so much. >> you're welcome. >> up next on "the lead," he was caught on tape pointing a gun at ferguson protesters threatening to kill him. now that officer is out of a job. he's not the only one. stay with us. vo: this is the summer. the summer of this. the summer that summers from here on will be compared to. where memories will be forged into the sand. and then hung on a wall for years to come. get out there, with over 50,000 hotels at $150 dollars or less. expedia. find yours. what does it mean to have an unlimited mileage warranty on a certified pre-owned mercedes-benz?

joining me with more is theen na jones. goog has been working on developing a drone for quite some time. >> the folks at google x have been working on this for two years. they're a super secretive bunch, the people behind the self driving cars and google glass. the reporter we spoke to said you can't even go to the restroom at their facility in the mountain view, california, without being escorted all the way there. now they've been working on something they hope will change the way society, would. >> hear that? it's the building buzz of potential business by drone. >> some dog food for my dogs, please. >> and now backed by a rock tune riff, google announced its latest aspiration, a drone delivery service for anything from dog treats to first aid kits. >> project wing, aspires to take another big chunk of the remaining friction out of moving things around in the world. >> moving things around namely products to paying customers is something companies like google are looking to streamline. it might seem like a strange move for google which has built its empire around searches, maps and advertise ago. >> what they want to do is have the world work more like the internet, right? they want all these little autonomous pieces working on your behalf. >> google is no stranger to innovation and expansion, like its driverless car prototype. the alexis maddrey gal was given exclusive access to the team behind the secretive drone project. he says google wants to transform the world, quickly delivering medical supplies and other goods to people in hard to reach places. >> the postal service changed society. fedex changed society. same day deliver changed society. don't we think being able to get you a package in two minutes would also change society? >> this time google is a bit behind. amazon introduced their prototype last december. and dominos pizza tried their own dom know copter drone in june of 2013. the coast guard already uses drones for surveillance on ice sheets in alaska. real estate agents are using them to show homes and they were even used to survey the damage after an earthquake struck nap pal california, this month. but widespread use is likely years away and a slew of important safety, privacy and technical issues have to be addressed first. the federal aviation administration is set to draw up rules to integrate drones into the national air space by december 2015. perhaps that's one reason google tested its system in australia. another big question, are we ready for this? privacy and safety issues aside, are we looking at a future where delivery truck drivers won't have jobs and we'll have thousands of drones flying around our cities? that's something a lot of people may find hard to imagine. other people say hey, bring it on. >> a lot of potential questions and problems there. and then na jones, thank you so much. in national news, our coverage from ferguson showed sunning images of police clad in kevlar holding semi-automatic rifles, cracking down on protesters. now two officers involved in the police response with you the off a job. lieutenant ray albers, a 20-year veteran of the st. ann police force gave back his badge and gun after a video showed him aiming at protests as he shawed i will kill you. the city of glendale, missouri, dismissed matthew papert. he wrote on facebook these protesters should have been put down like a rabid dog the first night. the nation reacted in horror when it learned about the tragic accident pond at i an gun ranging in arizona. now the victim's family is reaching out to the young girl who lost control of her weapon as we reported a 9-year-old girl accidentally shot her instructor while she was learning how to shoot an uzi submarine gun set on fully automatic. that will instructor, charles vacca, suffered a gunshot to the head and died. today they told her they want to know they do not blame her. >> he was a good person. we know they are, as well. we want to make sure we understand we know it was a tragic accident and that it's something that we're all going to have to live with. >> the daughter ashleigh says she plans on writing a letter to the little girl and her family. >> our sports lead, roger goodell says he messed up. the commissioner announced the league is changing its code of duckett policy regarding domestic violence. every player, referee, broadcaster, will be suspended for six games without pay. the punishment if they will do it again, a lifetime ban. while goodell admitted he "didn't get it right the first time" and the nfl has to do better, two words he did not say in that statement, ray rice. we cannot show you the video but rice, the ravens all pro running back was caught by security cameras dragging his then fiance wife out of a ca is inknow elevator. rice was arrested at the time but never faced prosecution. the league suspended rice for a mere two games over the incident. two games. mean weill, josh gordon,' wide receiver for the cleveland browns will miss the entire upcoming season after he was suspended for violating the league's substance abuse policy by smoking marijuana. whole season for marijuana. that's it for "the lead." i'm jake tapper. i turn you over to brianna keilar filling in for wolf blitzer. these right next door in "the situation room." >> thanks, jake. happening now, breaking news. new terror warnings, britain raises its threat level to severe saying an attack by islamist extremists is highly likely. what's the u.s. doing about the danger?
