mick says he'll be riding the waves again soon. remember, you can watch "the lead" anytime. go check it out. and tweet the show. that's it for "the lead." turning it over to wolf blitzer in "the situation room." thanks for watching\s. happening now s cnn learns that investigators are poring over the chattanooga gunman's writing, finding anti-american sent men even though one of his friends said he called isis a stupid group. and his fascination with high-powered weapons. isis claims one of them. hurling insults.

he's cringing almost everyone sees trump blames. media for distorting what he said. and un-contested. 99% of north koreans voters turn out for what observering describe as a sham election. will it make the undisputed leader even more dangerous? i'm wolf blitzer, you're in "the situation room." happening now, we're learning more details writings uncovered showing that he was displeased with the u.s. government's war on terror but one of his friends says abul seals was also critical of isis. this comes as isis says it's

responsible for a terror bombing in iraq that killed over 100 people as well as a suicide attack in turkey an important u.s. ally. dozens of people are dead there. meantime here at home a accomplice cal firestorm started by donald trump. is it backing away from comments most republicans think were an insult to senator mccain and all the former prisoners are wart. ed royce is standing by. he'll join us to answer questions about isis and efforts to start terror attacks inside the united states. our correspondents and analysts are also standing by with the latest information. let's begin with pamela brown, who is following the chattanooga shootings investigation, what's the latest? >> perhaps we're in the most important clues in the investigation so far are the writings left behind by the gunman. apparently written over a year ago, they give a window into a trouble young man who was

unhappy with u.s. policy, but what what turned him into a killer is still unclear. tonight in what may be the first hint at a motive cnn has learned investigators are combing through notes apparently written by 24-year-old mohammed abdulazeez and documents found in his home, he expresses anti-american sentiment and says he opposesed u.s. war on terror. one official briefed on the writings tells cnn they are consistent with someone having suicidal thoughts. >> if the ideation is there. if the use and abuse of drugs and alcohol are there, if the access to weapons are there now you have an individual that is at much greater risk for acting out violently. >> sources say the this mug shot

was taken three months ago after abdulazeez was charged with a dui. police say at the time he had a white powder under his nose. abdulazeez was dismissed from his job as an engineer at this nuclear power plant in 2013. he was apparently having trouble keeping a steady job. >> i knew his drug usage with marijuana and that he was kind of a big advocate but he did want to stop eventually. >> his friend tells drew griffin he helped him convert to islam, but never heard him express radical thoughts at one point calling isis a stupid grun. >> it was a stupid group and completely against islam. not to even think about going towards them. >> reporter: tonight investigators are also focusing on his trip to jordan last year. hi parents told police they sent him there to get away from friends they say were bad influences but investigators

want to know if he was exposed to radical thought abroad. this is still being treated by the fbi as a terrorist investigation, but sources say they still have a lot of work to do until they figure out a motive and whether he was inspired or directed by a terrorist group. at this point it appears far from clear-cut. >> it's still relatively early. pamela thanks very much. sunlen surfatty is on the scene for us. what does the family saying? >> reporter: they are really gift investigators a fuller picture of the personal battle he was struggling with. they say he had been using drugs for some time including smoking marijuana, taking some sleeping pills, and using other so-called party drugs. that is in addition to having -- taking some painkillers for the last year they say, for a back injury. they also saying revealing to investigators that he suffered

from the manic-depressive bimore disorder. they say because of that condition, and also because of his drug abuse, he was seeking treatment from a psychologist and we are hearing from the family they issued a statement over the weekend saying quote, the person who committed this horrible crime was not the son we knew and loved. for many years or son suffered from depression. it grieves us benonbelief that his pain found an expression in this heinous act of violence. we have cooperated with law enforcement and will continue to do so. they also expressed sorrow for the act of their son, saying there are no words to describe it. wolf? >> we know the bodies of the four marines as well as the sailor -- as well as the shooter, all of those bodies are now at dover air force base in delaware. i can understand wise the bodies of the u.s. military personnel are there. why did they say abdulazeez's body there as well?

>> reporter: that's a great question. first we know the bodies were transported separately so the body of abdulazeez was transported in a different plane than the bodies of the victims from here in chattanooga, we know the body is in custody of federal officials. that's like lie why the investigators wanted to receive his body as this investigation goes forward, but certainly a poignant moment here in chattanooga yesterday as there was an informal procession as the hearst of one of the last victims petty officer randall smith, as he was transported to the airport, his mother coming to the memorial afterwards putting a baseball mitt here so certainly a sad moment for the mother and really the community here wolf. >> sunlen thank you very much. evan perez has working his sources. how are is the investigators viewing this case right now? >> they classify it as a terrorist case simply because of you know what they have seen to far.

until they see otherwise that's the way they're going to see it. however, this is -- this suspect in particular this shooter, is a mess of contradictions. he -- you know he's drinking alcohol, abusing drugs while at the same time professing some kind of religious zeal. you can see some some of the writings including the blog posts that are believed to be his, that he seems to be following some very conservative views of islam. it's definitely confusing to investigators, because they don't know what to make of this guy. he doesn't fit into the box of some of the people we have seen who want to carry out attacks, for instance you know the fact he could have killed as many civilians as he wanted to that day, but was only aiming to kill military members. isis guys tend to not care who they kill. so he is posing some strange things to investigators. >> because we know that eye says has its own problems with other

terrorist groups like al qaeda, for example, so if he says isis is stupid maybe he believes that other terrorist group, whether al qaeda or some other terrorist group isn't stupid. i suspect that's what investigators are trying to fidget out. >> one of the things they're trying to figure out if perhaps he fits into another box, but the issue here is that he doesn't seem to have had any kind of direct inspiration. he seems to be cobbling together his own views along with the fact that apparently he was suffering from mental issues. so he's definitely not like a lot of the other ones we have seen before. >> i'm sure there's a lot to investigate. evan thanks very much. joining us in "the situation room", the chairman of the house foreign affairs committee, republican congressman ed royce of california. thanks very much for joining us s. so what do you think about this use -- his writings were critical of the united states didn't like the u.s. war on terror but we hear from a close

friend who says he told him only in reg days that isis was doing wrong, it was against islam, it was stupid what do you make of this? >> besides the messages coming from eye says there are other terrorist organization that are, as the fbi would put it making that tap-tap-tap on the shoulder of angry and disturbed young men around the world. there are a lot of them telling them kill kill kill. this young man in particular having spent over six months in jordan the fbi is very interested in that aspect of that last trip. he's made a number of trips over to the middle east but he came back a changed man from this last trip and in speaking to the fbi about it from the initial briefs i had, i think they're most interested in that and the other aspect is trying to go through his phone, and of course it would be much easier if these terrorist organization

didn't have encryption capabilities today. we don't know yet, but we may find that rather than speaking openly on the internet he had gone dark. that's one of the things they want to know was one of these terrorist organization communicating to him specifically or was this just the lone wolf who hansanswers the call and decides to take this into his own hands to carry out an attack. >> we know he had visited jordan for several months last year. we also know he was actually born in kuwait but visited kuwait i believe back in 2010. do we know if he visited any other middle eastern countries? as you know there's rumors out there he may have visited yemen. >> those are the two that i know of out of a half dozen trips, i only know of those two, but of course they border other countries, and i think they'll find out after the investigation

the full level of his visits. now, of course what the fbi is asking of the provider networks and the telephone networks is some level of cooperation now that they'll be able to get a court order in order to try to find what other information they can obtain about his trips overseas and who all he had contacted, because they would like then to be able to fan out on the investigation and learn more as a consequence. >> i assumed, mr. chairman the governments of jordan and kuwait two close u.s. friends are providing full cooperation. right? >> absolutely. jordan as you know is one of the countries threatened by isis. isis' man dade is to put the caliphate in place, and that caliphate would encompass kuwait and it would encompass jordan. those two governments will have a high degree of focus on

learning everything they can because of the amount of time he spent there, and because on an ongoing base they're trying to knock down the recruitment of their own citizens into this van guard of eye says as well as other terrorist organizations that seek to replace the monarchy or the government in kuwait with a caliphate. >> as you know some military recruiting facilities here in the united states have increased security in the wake of this terror attack last week. do you believe all u.s. military recruiting centers throughout the suns including orange county which you represent, need to have better security? >> remember we have marines stationed, you know. we have professionals who have been trained, and knowing that isis has made the request to carry out attacks against naval

and army personnel, as well as their requests to carry out attacks against unarmed police officers this is one of the -- one of the requests that they made worldwide in europe and the united states i think as a consequence, it would be a good deterrent to have our marines on the premises and other personnel to have that capability. it would have a huge deterrent effect. >> in other words, for them to be armed? >> yes, there will be legislation that will be brought up here probably next week on the house floor to do that and remember many governors have already done that in their states with respect to the -- the national guard. >> we have a lot more to discuss, mr. chairman. stand by for a moment but to wrap up this part of the discussion you don't have enough evidence yet to be convinced he was either inspired

or directed by a specific terror group, whether it was isis aqap or any other terror group? >> no. and i talked to the fbi about this case today. we are -- we do recognize that the fbi prevented ten separate incidents during this -- the past two-week period but this is one individual who got through, and the way he was able to carry out the attack is because there was no advanced warning in this case so now they have to dig in and find out the specifics of what motivated him to do it. >> all right. mr. chairman stand by. we have a lot more to discuss, including the latest terror explosions rocking turkey and iraq. much more with the chairman of the foreign affairs committee, when we come back.

the dret toll tirning to rise after a suicide in turkey. and it comes only a day or so after a suicide bomber with an ice truck lured about 120 people to thas deathed in iraq. we'll discuss this and more. stand by mr. chairman. i want to bring in our senior international correspondent arwa damon. she's on the scene.

>> reporter: we do have to warn our viewers that the video is incredibly graphic. cnn is showing it to demonstrated sheer inhumanity and horror of the attack. nic that ensues. this was a gathering of mostly kurdish activists who had come together to promote the rebuilding effort of kobani that

is in syria just across the border here that was the scene of fierce clashes and fighting that took place last fall between isis and the kurdish fighting force. this shocking everybody, yes, but not necessarily surprising wolf as this nation has been bracing itself for the violence in syria to spill across the border here wolf. arwa the other terror explosion in the past coming base hundreds more lures peer in ash ice truck.

in a predominantly shia town. 6 6. both these targets seems to be a deliberate attack to target society where it is most vulnerable. in iraq is the attack claimed by -- tried to increase tensions between that countries shia and sunni populations. possibly also concludes ago mostly kurdish target to deepen the fillsssures. but most certainly this will demonstrate just how many areas can be exploited when it comes

to this kind of violence and the potential ripple-on effect they could have in a region that's already fraught with so many various different kinds of attacks and multiple front lines, wolf. arwa thanks very much. be careful over there, as i always tell you. arwa damon on the scene outside of the terror attack in turkey. n kurdish youth. a secular political movement. which i think for isis is a special target going after any secular institutions and of course in iraq the attack were

on young people coming to get ice, families and again in that case service shia so their intolerance for any other viewpoint other than their own has led them to develop a new type of lethal weapon. you have seen some reporting over the week about the way in which isis is now trying to use gas, and that fireball that you saw in that attack that wounded over 100 kurds, is the kind of lethal weapons their trying to get their hands on right now. they won't allow u.s. airplanes to use turkish air bases. so is this a game changer right now as far as getting more cooperation from turkey in the ward against isis?

i had a meeting last week to talk about the possibility of a safe zone where turkish and u.s. authorities from in order by the way to prevent the barrel bombs from being dropped by assad's air force there. i just think that turkey is at a point now where they have several million refugees as a consequence partially of what isis has done and partially because of brew taught of assad, so i think that they are beginning to go through a mental calculation that maybe they should cooperate with the united states in creating a safe zone there for refugees and in helping push back isis. a final question on the iran nuclear deal. as you know the united nations

security council today unanimously approved the iran nuclear deal. even though the u.s. congress is only now beginning the process of considering it over the next 60 days. do you believe you -- and i think you're pretty critical of the deal. will u6 enough of a two thirds majority in the house of representatives -- in other words, 290 members, to override a presidential veto that president obama promises will occur? >> well wolf i think we still have to go through the details of the arrangement, but i did make the same request that democrats and republicans on the senate foreign affairs committee made to the white house, and that i and eliot engel have raised as an issue. democrats and republicans have suggested don't go first to the united nations to lift the sanctions that pertain to the ballistic missile systems. first let us go through our process here because i think in

signing the bill the administration basically commit it hadself to a process in which members of the house would be briefed by the secretary of state. instead, the day before the briefings, this approach was made to the united states to lift the sanctions there. it was our request that that be stayed until this 60-day time frame. i think you'll full that everyone from democratic majority leader -- minority leader steny hoyer speaking out to senator ben cardin ranking democrat in the senate on this so i think there are some concerns in the way this is being handled. >> do you have enough votes to override it if necessary? >> i don't think anyone knows, wolf at this point the answer to that question. i think a lot will depend on the details come out. we have 160 pages at this point, which members of the house and members of the senate received on friday and i think we'll

start that process this week of going through the details of the agreement and i think we'll reach a conclusion after those hearings and after we have heard from our secretary of state and others involved in the negotiation. ed royce, chairman of the house foreign affairs committee, thanks very much. >> thank you. coming up donald trump still doesn't feel like apologizing for what he said about senator mccain. will his remarks hurt him with republican voters. and an election where nearly everyone votes and a winner is guaranteed. stay with us. rom at&t? yeah, give me a problem and i've got the solution. well, we have 30 years of customer records. our cloud can keep them safe and accessible anywhere. my drivers don't have time to fill out forms. tablets. keep them all digital. we're looking to double our deliveries. our fleet apps will find the fastest route. oh, and your boysenberyy apple scones smell about done. ahh, you're good. i like to bake. with at&t get up to $400 dollars in total savings on tools to manage your business.

is a. we're following a number of new leads, investigators now telling cnn that mohammed abdulazeez left behind writings with anti -- but a friend says he was also critical of isis calling it a stupid group. joining us is tom fuentes our cnn law enforcement analyst, the forensic psychologist dr. lisa van usser, and paul cruickshank. his family says he was having mental issues quloog drugs, bipolar, but his friends say he was unbelievable nice guy. he said eye says was doing stupid things, what are you seeing here? is really not realistic. the fact is, with and we know this from court documents that there were years of physical

abuse, violence beatings to him and to his siblings. this is the substrate, the foundation upon which so many other things can happen. to say it's a mental illness is not realistic. the second thing is when they say he was a nice guy, there's countless times the allegations were continuing to force -- >> years. >> he supposedly was abusing the mother sexually physically and abusing the kids as well. the couple stayed together though. >> that's correct. >> so not necessarily a healthy environment there. his close friends, though say he was quoted as saying isis was doing wrong. what do you make of that? .

when they say things like that it makes it heart to say he was isis-inspired if he's telling people that isis are doing stupid things. that just adds to the complexity of what he believed or who he backed up or what. in a ways it's irrelevant who inspired him, because just being inspired isn't enough to prevent a future similar occurrence. >> paul there are other terror groups who also think that isis is doing stupid things. they're anti-isis, even though they themselves are terror groups, there is a split, for example, between aqap and isis. >> that's absolutely right, wolf but in the interview of the close friends with drew griffin, he was signaling that he was also opposed to the other kind of islamist terror groups as well. so there's a lot of head scratching going on at the moment. it seems there's some kind of mix here between radicalization but also mental health issues

we have seen that in a string of recent plots and attacks in the west notably in that hostage siege in sydney, australia in december. it turned out the gunman was seeing two psychiatrists, was paranoid, delusional. we also saw mental health as a factor in that shooting in ottawa. that shooter was also taking a lot of drugs. and also in the attack in new york in october, again a mental health component. so there seems to be some kind of mix between radicalization and mental health issues. people with mental health issues that can make it easier perhaps to go from radical thought to radical action. >> let me let lisa weigh in on this because you study this. >> yes. the reality is when people have murder os rage like this they will seem to justify it. if he wants to wrap it in a ideology political, religious or otherwise are el otherwise, that would be his justification.

the other thing is when people say something is stupid they don't embrace it you can't take that entirely seriously. that might be their own sense of denial repudiating what they know is a growing force that is gripping them that is obviously a violent -- that are they predisposed to they don't want to act upon but they eventually do. >> he was a smart kid, with a degree in electrical engineering. he had all sorts of potential. they said he was a very good student. >> that's not inconsistent with having a murderous rage. this is the foundation upon which so many other things were built. he lost jobs. it sounded like he was living at home this is the classic case of a guy who feels like a loser, he's full of rage and blames other people. >> we know he got that job at one of those nuclear power plants no ohio but after ten days they got rid of them. >> and let's at one more

thing -- the ability to get his hands on an assault rifle, and not prevent him from getting the weaponry and firepower he needed to carry out the attack. >> as you know he apparently was using guns a lot. he was training ever since he was a young man, paul. somebody who may be having serious mental issues but has access to high-powered weapon. >> that's right, wolf al qaeda in particular having encouraged their followers in the united states to take advantage of what by international standards are lacks lax gun laws to gout and buy a weapon and shoot up soft targets in the united states. this will be a very big problem moving forward. it's easier for lone wolves in the united states to launch thinks kind of attacks that can in the rest of the western world. paul lisa tom, thanks very

taken before -- at least most of it was taken before trump set

off a political firestorm by questions whether john mccain is in fact a war hero. we are not seeing any hints of an apology from donnell trumped. brianna keilar is watching. >> it shows that trump is in the lead with republicans. there was a sharp dip following these comments. >> i supported him, but his lost. so i never liked him as much after that because i don't like losers. but frankly -- he. >> he's a war hero. >> he's not a war hero. he's a war hero baas he was captured. i like people who weren't captured, i.

he's a war hero. perhaps he's a war hero but right now he said some very bad things about a lot of people. >> almost immediately his remarks drew scrutiny but he would not and has not backed down. most of his republican candidates now pounced on his remarks. here's what they are saying. >> this is a legitimate hero that has served his country in lots of way, and mr. trump knows that. he should just apologize. i think that would probably move it to the next thing. next week there will be another one. >> anyone who suggests that john and his fellow pows are somewhat lacking at the title of being called -- you shouldn't be or commander in chief, because you don't know our military. >> establishment republicans are no fans of donald trump and they're hoping this is the beginning of the end for him. our jake tapper just talked to

north koreans flocked to the polls over the weekend to vote in the election that gave them no way of up kim jong-il's. what are you learning? >> well a u.s. official says he's leave nothing doubt as to who's in charge in north korea. these elections are a sham and we're told even the balloting is used as lever for kim to solidify his grip on power. it's a big event in north korea.

women dress in long gowns. men in suits. it's voting day, where people cast their ballots for provincial city and people's assemblies but here voters are handed ballots to place in a box. the candidates, the winners predecided by kim jong-il's government. for each election there's one candidate on the ballot. a vote against the selected candidate goes into the separate box and a no vote is considered an act of treason and is not showing up to vote. >> they may be go to political prison and knowing how north korea works they could even have several generations of a family go to the gulag for the crimes of one person who may be voting against a candidate that has been pre approved or not showing up to vote. >> north korea's government says for this election over the weekend voter turnout was 99.97%. analysts say for kim's regime there's an unsettling strategy behind the balloting.

>> it is a way of checking up on people, are they where they're supposed to be? if someone doesn't show up that may indicate they tried to defect or they're moving elsewhere in the country. that it's something that the central government does not want. >> this comes as kim continues a bloody campaign of purges keeping senior member of his regime on edge. south korean intelligence said he's executed 70 top officials including his own uncle. far more than his father did in his first years. analysts say with the reported execution of defense minister with an anti-aircraft gun this spring he's gone through at least four defense ministers. >> this is a fight between generals and admirals and kim jong-il and it's not over yet. >> does this mean kim's threatened from within? a u.s. official tells cnn kim has has carried out the purges without repercussions, but some believe he's looking over his
