the apparent source. i'm wolf blitzer. you're in "the situation room." the hunt for two escaped murderers spreading to vermont. police say they are looking behind every tree for the fugitives, who are considered extremely dangerous. the governors of both states have warned the public to be very, very careful. also breaking now, the white house says up to 450 more u.s. troops will be sent to iraq to train and advice iraq's military. an official now says the goal is also to have u.s. troops train sunni tribal fighters to rise up against isis. i'll speak with senator tom cotton of the intelligence and armed services committee, and our correspondents analysts and guests are standing by for full coverage. let 'best gin with barbara starr. what is the mission snow? >> wolf a bit of confusion about that. we've heard for weeks that they

want to training more iraqi fighters to get into the fight. here at the pentagon today, however, the focus was on something caused advise and assist. what does that mean? try to help the iraqi fighters get more organized, teach them how to launch conditions but not necessarily train new fighters right away. so a biof confusion, but it does seem that they are going to focus more on looking at the sunni tribes. they have to get the sunni tribes involved in the fight. it's a you will good going west into anbar province getting the sunniss to join the fight, key to pushing eye says owl, but the question is can they get the sunnis to join the fight. they're very kept cal about the shilla ld government in iraq. how exactly are they planning to get the sunnis there to take up

the fight? >> well you have it look at the map. it's interesting. the u.s. troops will go to a new location called the al taqqata base this is near the combat zone. they're going to engage in rout reach to get the sunnis to basically come into the fold but this now opens the door to trying to reach out no the tribes. if it does come to that even if they think the sunnis will come to this air base this is an area of extreme combat risk right now, an area where these u.s. troops are going to need a lot of protection. wolf? >> so the immediate focus is ramadi the anbar province but only a few weeks ago general dempsey said you know what? ramadi not necessarily all that

strategy ecimportant. the oil refinery that was strategically important. has there been a change of heart tess pentagon? >> right now, it looks like everything the white house and the pentagon announced today is focused on anbar province. 450 troops going to this base to this location now that has been identified. advise assist get the sunnis try to get them to come into the fold. what you are underscoring is the key point, iraq's problems now getting security pushing isis out. it is really across the country. they have to priority ice. they don't have enough troops to do it all, so right now a shift of priorities get anbar taking care -- try to get ramadi back under control. continue to fight in badgi, and what about mosul. >> mosul might not even be

addressed. thank you, barbara. against isis can more u.s. trainers and advisers make a real difference? let's bring in our chief nationality security correspondent jim scuitto, what are you learns? >> u.s. officials believe they can make a difference. they say they have a commitment from sunni tribes in numbers to take on isis with this u.s. help and is a key to the fight which to now has been shiite-dominated but no one, to be clear, is claiming an immediate payoff. u.s. troops on the ground training iraqi forces in urban warfare. soon the u.s. will have 450 train ner support teams to the 450 trainers already on the ground an effort to turn the iraqis into an effective fighting force after a series of debilitating loss toss isis. one years after the terror group swept into iraq almost unchallenged the battle remains

at best a stalemate on the key urban battle grounds, ramadi lost to isis in late may. baiji, home to a keep oil refinery still contested. mosul now an eye says stronghold plans by recaller delayed indefinitely. >> if you expect the new u.s. strains yesterday they were attacking around baghdad. they're on the move in syria and everywhere else. we need a change in strategy. trainers is a start, but it's not enough. the president's move failed to satisfy iraq hawks or doves. >> it's a step in the right direction, but as the president admitted the other day, he has no strategy to win. what this is -- this is another

tactical move. some democrats see mission creep, a new risk the trainers are positioned closer to isis' front line. >> this is exactly how vietnam started. if you don't think you're putting them in harm's way, you're not lives in the real world. >> you'll remember wolf just a few weeks away when i was in the briefing room when martin dempsey said that ramadi was not a key location places like baiji were with the olympic refinery. now clearly ramadi is a priority after it's been lost to eye says forces this key debilitating loss for the iraqi security forces with this increased deployment of u.s. forces there. it gets to the question, what is important? which which of these city says key? this one wasn't a month ago, now apparently it is to the tune of 450 additional troops. >> it wasn't that long ago that the u.s. military central

command that could be a spring offensive, and now we're hearing that offensive may not take place until next year. >> it was interesting when i went to iraq last year commanders on the ground said at least months ago. then the beginning of this year earliest in the fall but could likely fall to next fall. i think it's far more likely it's delayed to next year particularly with the performance of iraqi forces in recent weeks. >> jim scuitto reporting for us tom cotton of arkansas he serves on both the intelligence and armed services committee, served both in iraq and afghanistan. senator, thanks very much for joining us. >> good afternoon, wolf. good to be on with you. >> thank you. >> you hear barbara starr report about the new plan to deploy another 450 troops to iraq to start training assisting advising. is this a good idea?

>> wolf it's a step in the right direction, but the president still doesn't have a strategy. he's simply throws a few hundred more troops at what was already an arbitrary troop level. he's knocked that a cup the dab frankly remind me of what i saw in recall as a lieutenant in 2006 when we were clearly losing the war and it was only when the surge didn't just add troops but changed strategies we put ourself on the past to victory. >> first, the president neither to lift the arbitrary cap that he has on troop levels and led our commanders engain in the decision-making process. i think they'll come back with sdanch not mechanicized troops not hundreds of thousands of troops like we had in iraq but rather specialized skill sets. forward air controllers to make

our air strikes more effective, special operations sourceses to help train the iraqi forces. battalion-level advisers when his own undersecretary of defense recommended recently. and these are all a substantial shift from the president's current path but they would also give the army the tools they need to help fight the islamic state. >> these would be combat forces on the front lines, obviously be at severe risks. do you worry about that? >> wolf i always worry about our troops, but i worry also that the islamic state is rampages across syria and iraq setting up franchises all over the world, constantly trying to attack western interests, trying to attack us at home in the united states. the united states is the only country in the world that has some of the capabilities needed to help the iraqi government to help the sunni tribal leaders in western iraq and help the kurds in northern iraq to defeat the

islamic state. >> but if the iraqi military isn't showing the will if the iraqi government is so divided, they don't have the capability to do it why should the united states do go in and do what the iraqis should be doing? >> we wouldn't be doing what they should d. but help them achieve what they should be doing. i saw it in afghanistan as well later. many of these local fighting forces are capable of fighting but we have unique capabilities that we can provide. we also get incredible boost of more real and confidence whether we provide those assets and they seeing our special operations forces there advising them at the battalion level. we see forward air controllers making the air strikes much more effective. whenever you're fighting in ramadi and you don't have those assets and the islamic state is driving in humvees with explosives bigger than the oklahoma city bombing, of course it will have an effect on their more real.

senator, stand by. we have much more to talk about whether or not this entire operation could even be won militarily. much more with senator tom cotton, when we come back. dear stranger, when i booked this trip, my friends said i was crazy. why would i stay in someone else's house? but this morning a city i've never

nor tom cotton also served combat tour in both iraq and afghanistan s senator, i recently have phone with three four-star general, a four-star admiral. they all told me this fight against isis really can't be won when it's all said and done it has to be up to the iraqi people. do you agree? >> it can't be won only militarily but there is a military component to it. we have to help provide security to the local population. again, we saw this in a surge in 2006 '07 and '0823 the local civilians don't believe that the government and u.s. forces there at the time can provide that security then they're going to regrettably side with al qaeda and iraq. if you contrast northern iraq where the kurds live and somewhere the sunni tribes live you'll see a good example.

in northern iraq the kurds are largely hostile to the islamic state and mostly able to beat back their advances but in anbar where you have sunni tribes that are often choosing that's not a very good choice they will choose sometimes the islamic state. we would like for them to support the iraqi government because the iraqi government with our assistance can provide security to them. if the iraqi military doesn't show a will to fight as ash carter recently suggested, should the u.s. simply pack up its bags and leave? >> no, unfortunately we can't. if we were to do that the islamic state would continue its ramp answer might even conger baghdad and raise the flag -- and that would produce them more to u89ly attack america right here at home. we have to win this fight again

the islamic state. that's the president's stated goal to he's simply not providing the resources need to do achieve that goal. >> you went to harvard law school you graduated, a lot of lucrative career opportunities ahead of you, but you decided to join the united states army. you have deploy to do iraq in a combat role. i guess the bottom line question knowing what you know now, what is going on in iraq, would you do that again? >> wolf absolutely i would leave my law practice and join the army again if i had the chance. it was one of the great privileges of my life to lead my fellow americans in combat in defense of our freedoms and safe and security. of course like all veterans who serve there, i'm heartybroken when i see places like fallujah ramadi and mosul fall to the islamic state. that means in my mind we have to redouble our effort to make sure we don't squander the victory we had in hand a few years ago, and

we commit to defeating the islamic state. >> what do you say to the families of the 450 troops that are about to be deplied though this dangerous area the 3,000 other troops who are there right now? >> well i say they and their loved ones serving, they are in my prayers and the prayers of they are fighting in a noble effort. i think we need to send a few more troops with more specialized skills but the 450 troops who are going there are going to iraq not just to fight over a piece of land but protect a way of life our life here in america, and i'm grateful as all americans are. >> senator tom cotton thank you for joining us. >> thank you, wolf. the man hunt continues into vermont. the governors are warning the public to be very careful. the am track mystery deepens. the passenger train's engineer wasn't texting or speaking on his phone, so what caused the deadly high-speed crash?

let ate get back to the breaking news. up to hoo more u.s. troops will be going to iraq to train and advise iraq's military on the front lines. a u.s. official says the goal is to train the sunni tribal fighters to try to rise up

against isis. joining us philip mudd peter bergen and or global affairs analyst, colonel james reese a former army delta force officer. you say not all will be involved in training iraqi forces. would you expect them to end up on the battlefield on the front lines really combat forces for all practical purposes? >> let's not kid anybody, where they're going with ramadi and fallujah they're about as close to the front lines as you can be. i would expect there will be attacks with indirect fire. once the americans get there in that location isis will try to want to do some attacks. but anytime when we're trying to send in forces you can't go oh, there's 400 trainers going on. there's a big tail that comes behind that.

probably almost half of that will be a force that's there for force protection security logistics, so maybe about 50 of these folks broadband trainers to deal with the next element and iteration. >> the colonel makes a good point. what worries me is these forces u.s. troops heading to the front lines for all prabs purposes they're going to be dependent on the iraqi military to protect them and i'm worried about that iraqi military as the defense secretary says they have haven't shown a great will to fight right now. as you know isis terrorists who are there on the front lines, they would likes nothing better than to capture an american soldier or two. they have them as targets. >> sure. isis's sort of world view they actually want western troops to come because they believe that would be part of the end of times, when the van guard is ushering in this end of times and a final conflict between the west and islam in which they're the van guard troops.

this for them confirm what is they believe to be a serious islamic prophecy. so of course in reality it would not be helpful to have western american troops there advising really in anbar as the plan seems to be. >> but if it happens, phil if they capture an american soldier or two or whatever and start you doing propaganda video with this individual -- >> i think you have to have one aspect of that. at this point in the time the fight for baiji, for example, as we've seen shia militias i think what isis would try to say, this isn't just the government versus us this is the shia fighting the sunnis and look who is in that's the americans, you see versus them. >> colonel reese, you just render a little while ago from iraq you saw what was going on firsthand. the u.s. says they will be

providing weapons not only to the regular iraqi mill tar, but the peshmerga, the kurditious forces as well as some of the sunni tribes and it's a very important but, all those weapons still have to go through the iraqi government in baghdad. is that still a good idea? >> wolf it may not be a good idea but it's the idea and that's what has to be. with can't go out there and unilaterally side with a different faction out there, like phil just said we have to work the process. we have to work the diplomatic process. but let me make sure everyone understands this. the kurds are very good at this and they're very good soldiers and they want the information, but we have british soldiers up there, australian soldiers up there, all right? and those countries are also feeding into the kurdish forces also. so sometimes we start to look through the straw and everyone is just looking at the u.s. as the big player in the field, but there's other large coalition

elements up there. it was confirmed today a massachusetts native was killed in -- the kurds say he was a martyr killed near cobanni. what do you know about this if any? >> not much. we have seen a number of westerners and some americans who volunteer to fight with the kurds, and for ideological reasons they're opposed to isis there is something call the the neutrality act which technically americans aren't supposed to get in gauged in conflicts we're not party so. so on a very technical issue, these people could be charged with defying the neutrality act in some way, but of course we are arming the groups they are fighting with. so you know there's not much -- there's no appetite for the government to go after these people for this kind of operation. >> there seems to be philip a

very fascinating development in libya right now. we're getting these reports that isis fighters are fighting al qaeda fighters. there seems to be a real war developing between al qaeda and isis. what do you make of this? >> it's sort of like what we're seeing in syria. believe it or not, despite the fact that isis shares some ideology al qaeda does not want to join the caliphate. their view is wait a minute we had didn't sign up to join your fight. isis has carried that ideological fight into libya, and i think there's a great risk there. they're not only taking over cities but they're getting embroiled in fighting with group that say we don't want to sign up with you. if you try to keep moving we're going to fight. this is a rep pit for faxal alal alal alal alal -- recipe for factional fighting. >> some would say let them fight to the death, if you will. what do you say? >> absolutely.

if they want to fight it out and they want to do it down in the deep desert of libya, absolutely go for it. >> guys we'll stay on top of this story. we're following the breaking news obviously. thank you very much as always. coming up there's other breaking news we're following, as the man hunt for a pair of dangerous escaped killers, that now expanding into the neighboring state of vermont. later, the mystery deepen investigators rule out a leading theory about what may have cause theed deadly am track derailment in philadelphia. so what are they looking at now? big day? ah, the usual. moved some new cars. hauled a bunch of steel. kept the supermarket shelves stocked. made sure everyone got their latest gadgets. what's up for the next shift? ah, nothing much. just keeping the lights on. (laugh) nice.

doing the big things that move an economy. see you tomorrow, mac. see you tomorrow, sam. just another day at norfolk southern. across america, people are taking charge of their type 2 diabetes... ...with non-insulin victoza. for a while, i took a pill to lower my blood sugar but it didn't get me to my goal. so i asked my doctor about victoza. he said victoza works differently than pills and comes in a pen. victoza is proven to lower blood sugar and a1c. it's taken once a day, any time. and the needle is thin. victoza is not for weight loss but it may help you lose some weight. victoza is an injectable prescription medicine that may improve blood sugar in adults with type 2 diabetes when used with diet and exercise. it is not recommended as the first medication to treat diabetes and should not be used in people with type 1 diabetes or diabetic ketoacidosis. victoza has not been studied with mealtime insulin. victoza is not insulin. do not take victoza if you have a personal or family history of medullary thyroid cancer

multiple endocrine neoplasia syndrome type 2, or if you are allergic to victoza or any of its ingredients. symptoms of a serious allergic reaction may include swelling of face lips, tongue or throat fainting or dizziness, very rapid heartbeat problems breathing or swallowing, severe rash or itching. tell your doctor if you get a lump or swelling in your neck. serious side effects may happen in people who take victoza including inflammation of the pancreas (pancreatitis) which may be fatal. stop taking victoza and call your doctor right away if you have signs of pancreatitis, such as severe pain that will not go away in your abdomen or from your abdomen to your back with or without vomiting. tell your doctor about all the medicines you take and if you have any medical conditions. taking victoza with a sulfonylurea or insulin may cause low blood sugar. the most common side effects are nausea, diarrhea, and headache. some side effects can lead to dehydration, which may cause kidney problems. if your pill isn't giving you the control you need... ask your doctor about

non-insulin victoza. it's covered by most health plans.

the search is nor expanding to the neighboring state of vermont. the governors of both states say the police forces are working together and have called on the public to report any suspicious activity. hundreds of searchers are on the case. brian? >> tonight we get a real sense this man hunt is growing more intense, more stressful for residents in the surrounding areas and for these fugitives. they're giving's inside look on how they're trying to elute capture. >> investigators believe that joyce mitchell who worked in the taylor shop, planned to pick them up after their escape but according to a source familiar with the investigation, she changed her mind and was a

no-show. >> what now for these guys? >> well i mean they're obviously in panic mode. their plans aren't going the right way. >> tonight as the search expands, we're getting new insights from former u.s. marshals on how the man hunt is unfolding. what are the techniques matt and sweat could use? >> they lose weight gain weight grow a beard, shave, cut their hair short, color their hair. there's multiple ways to change their appearance. they're probably looking to break into some houses change their clothing get new gear. >> they might be dressing like women at this point in time. >> the escapees have been known to go to the extreme, plastic surgery. eric rudolph, wanted for the 1996 olympic park bombing,h hid for five years in the mountains of north carolina. and a fugitive who killed a washington area doctor while on the run.

>> welsh could really charm you easy will. the -- and he a girlfriend. she didn't know anything about highway. >> reporter: marshals have been to be creative they get in touch with relatives, former lawyers. they could still be moving together. what's the stress doing to them? >> i'm sure they're arguing, they're both psychotic in their own right. they each have their own way of doing things. they could be fighting over which way to go. >> but the tres isn't just on the fugitives. former marshals tell us every law enforcement official involved is working long hours, and every hours that goes by adds more stress. in the back of every law enforcement official's mind the desire to catch these killers before they hurt someone again, they're under -- >> and these kinds of fugitives often make their wind up.

>> it's fascinating. they're telling us these fugitives on which slip up by contacting relatives. they say a lot of these people may be getting surveyed by law enforcement. if they contact them that may be a way to get them. sometimes this if they steal a car, someone could report the car stolen. they're looking for just that one break. if they contact someone, try to steal a car, just one break to trace these guys. we'll see if they get that break. >> brian, thanks very much. at this afternoon's press conference officials sill at least another 450 officers are looking for the escaped murderers, following more than 500 leads. let's get more on the expanding man hunt. jason carroll is joining us from just outside the maximum-security prison. what's the latest you are hearing? >> reporter: you can imagine they are redoubling their efforts, retracing their steps, knocking on every door looking

behind every tree doing whatever they can to try to find these men, following up as you say on hundreds of leads, including one lead that leads them to believe that perhaps these men discussed a plan to head to vermont. >> we have information that suggests that they thought new york was going to be hot, vermont would be cooler in terms of law enforcement, and that a camp in vermont might be a better place to be than new york. >> reporter: investigators are also operating on the theory wolf that these two men may have had as much as several hours of a head start. new york's governor saying look they've got to follow up on all the leads, including questioning the prison employee joyce mitchell who worked here who knew these two men. she, as you know was questioned this past weekend. there were allegations that she tried to help these two men orchestrate their escape. earlier this afternoon, i spoke

to her daughter-in-law paige mitchell who told me quote, it's appalling to me. i'm totally disgusted that anyone would think that she would knowingly help them. she would never want to help a criminal. she would never want a criminal near her family. again that's paige mitchell. she also said her mother-in-law in no way provided any power tools to these men. you heard this discussion about whether or not she may have tried to help them on the outside. when i asked paige mitchell about that she called it quote, outrageous. one final quote from her, she said her heart was in the right place, she was trying to do something nice and it backfired. wolf? >> she has not been arrested. is she cooperating with law enforcement? >> reporter: she is cooperating somewhat with law enforcement. that's what we're hearing from sources, but again when i spoke to paige mitchell she said that after she was questioned by law enforcement, that was right after she had actually gotten out of the hospital this past weekend after admitting herself

for nerves. she said much of what is out there. in fact she said 95% of what is being reported about her mother-in-law, she says is simply not true. >> jason carroll we'll stay in close touch. thank you very much. a new clue that's been revealed as investigators try to pin down the cause of that deadly am track derailment. also breaking now, new information about the suspects in the theft of nude photos of prominent celebrities, including the movie star jennifer lawrence. mark and alissa anderson recently signed a 30-year mortgage on this home. they must be confident about the future. are you? buy in. quickenloans/home buy. refi. power.

now the national transportation safety board is ruling out a leading theory about what caused that deadly am track passengers train derailment in philadelphia. eight people died. 200 people were injured when the train ran off the tracks when trying to round a curve at more than 100 miles an hour. cnn's renee marsh has more. what are you learning tonight? >> tonight a major breakthrough investigators can take one theory off the table, but that only deepens the mystery surrounding why the train decelerate decelerated. the ntsb says that the 32-year-old engineer brandon bostian was not talking or texting on the cell phone when the train jumped the track. investigators appear to be struggling to understand why the train accelerating approaches a turn going from 70 to over 100.

investigators have found no problems with the track's signals or the train. >> they've eliminated you know most of what we call the low hanging fruit. now they're going to have to zero in on the behavior of the engineer. >> reporter: today on capitol hill the ntsb cautioned their analysis of bostian's cell phone is not done yet. >> there are 400,000 pieces of data involved in the analysis and because of the extent of that things like use of an app, or other use the of phone has not been determined. >> there's still no explanation for what caused the shatter pattern on the windshield. the fbi says it was not a bullet. it's unclean if it was hit by some other projectile. . the late-night crash left eight people dead and more than 200 injured. government-mandated technology called positive train control was not installed on the tracks
