This is what the kremlin has issued in their statement, they are saying, any versions regarding the incident and its causes may only be voiced by the investigation. We have not heard of any statements from the investigators so far. Any other statements are unverified information or some kind of speculations. Speculation. The kremlin here is trying to push back and make it appear that this information is somehow incorrect. But theyre not offering their own analysis, what weve heard is that metrojets others have been grounded. It does appear for moment that the waters here are being somewhat muddying. Michaela. Nic, thank you for that. After dismissing isis, what got officials to take another look. Well, it turns out that chatter online after the plane went down got some attention. Barbara starr. Good morning, michaela, as you said, all of this being looked at. None of is certain. U. S. Officials do believe it is potentially likely that the plane was brought down by a bomb onboard. Either put on the luggage or somehow smuggled into the plane. That is why youre seeing so much focus on security at Sharm El Sheikh airport. Theyre not offering a lot of about the intelligence they do have. They say after the attack, they monitored isis chatter. That is whats leaning them towards isis or isis affiliate. It will change the calculation of what isis is capable of, if theyre able to bring down an airliner. Do they have a bombmaker themselves that is able to put together some type of device. Or did they basically hire someone to do it. All of these still questions very closely being looked at, alis alisyn. British Prime MinisterDavid Cameron set to meet with the egyptian president. Clarissa ward has more. Reporter good morning, alisyn. Well, the time of this could not be more awkward. The egyptian president just arrived yesterday afternoon. Hes expected to sit down with prime David Cameron in the next few hours. This comes after the british announcement that theyre temporarily suspending all flights to and from Sharm El Sheikh. It was the secretary who made the announcement late last night after an emergency government meeting, and he said they had concluded that there was, quote, a significant possibility that the crash was caused by an explosive device on board the aircraft. Didnt go into any details as to what the intelligence is behind that claim, but certainly, it does appear to be in step with u. S. Intelligence. The Prime Minister is now in another emergency meeting. Likely, hes discussing how to get all of those british stranded tourist back from Sharm El Sheikh to the u. S. That could start as early as tomorrow. Clarissa, thank you very much. This is setting up as a simple crime analysis, you have means, motive and opportunity. Its a simple analysis here. Lets bring in ambassador thomas pickerling, former ambassador to israel and jordan. And michael weis, go author of isis inside the army of terror. Lets start with you, ambassador, motive, for isis to start a russian plane would be . Is the most obvious would be syria. Theres a question about how many or what percentage. But that could be a reason for them to go after a russian charter airport in Sharm El Sheikh, where they may well have collaborators. The Sinai Peninsula has been for more than a year a wild west zone with egyptian control over big pieces of territory. All right. Now that is the possible scenario that the ambassador is putting out. Michael weis, youve studied the area. On the isis hit list, you would say russia is relatively low . No, actually, if you look at the sermon from july 2015, he names russia specifically because of the war in chechnya. And phrased with Something Like america and russian backed by the jews are responsible for this conspiracy. So you think that isis could take up the chechen call as well . Well, theyve got loads of chechens and russian nationals from just the and that would feed the blood loss that they have for russia. The idea of this being blowback, as the ambassador said, if you look at it, most are not against isis. Its against the free army. What do we know about isis and bombmaking . Well, these guys are extraordinary adept and they really came into their own in iraq. They were masters of the vehicleborn explosive devices. Theyve retrofitted cars to blow through checkpoints. They have whole bombmaking factories in iraq and syria. The question is, chris, is this coming from isis Central Command or the farm team, if you like, the affiliate that declared allegiance to isis but started out as its own franchise. And also. This is a group that openly advocates anybody to do anything that is terrible . Absolutely. But these guys, last july, they had gotten involved in a fierce fire fight with egyptian personnel. Egyptian government said we had to fight them like a conventional military, not like a guerilla insurgency. We have the capability of how they might target it. Ambassador, that takes us to the opportunity of the witnessed doughs striking a russian jet. That may end up being a function of an inside job. You know this ground and security very well. What do you think about the opportunity here . Chris, the airport has lacked security, so, i think that adds to it. In addition to the conversation we just had, as you know, russia has been supporting president assad for three years and a half or so. And they, too, given the isis contention in syria would add to the number of reasons why they might go after it. So i think the security is poor, probably has some reality to it. The egyptians, of course, deeply hurt by that, because they depend heavily not just on sharm but other areas of traffic. And the british have shut that down. Is an allegation in the face even the president by president azhizhi to britain, sending other precautions and people to sharm and look at the question of how they can get the 15,000 people out of there without using the airport which is going to be a serious feat. Parse the language for us. As we all know, bomb signatures pretty easy in terms of sophisticated analysis done in a case like this. What do you make of the language from the United States using likely, possibly, the same were the brits. And then obviously a bigger step back from russia, and a full step back from egypt in terms of moving away from this. Three points, fairly like, because they have a relationship with egypt. Fairly indicative because they are leaking it or saying it. And as a result, they have something to go on and we have seen perhaps chatter between isis people, and they make that an important part of the case. Final point, look at lockerbie, it took a long, long time to find the computer chip made by swiss expert that apparently played a role on the detonation of that bomb. So, evidence on the ground may be harder to find. That may be what you need to lead to this in addition to the intel work. Certainly, on the intel side of who did it. It will take time and sophisticated analysis unless you get a big leak. And with meat on the bones. Bomb signature, michael, they should be able to know that . Right. One of the possible pieces, is the footage showing the heat explosion. That doesnt mean necessarily an explosive device is on the pl e plane. Lots of things systemically can go wrong with the plane . Right. Remember, this particular plane 13 years ago sustained damage because it was trying to take off. And the hail hit the runway and i think was cracked open. So they repaired the plane and then subsequent owners. And this company metrojet said, no, no, theres no sign of wear and fatigue but not compression. Who knows. Were trying to piece together using that. The u. S. Is probably relying heavily on signature intelligence, intercepts between sinai and Central Command. And the line of sinai, if theyre putting together video, this is how we did. Isis is famous for the slickly produced propaganda videos. They might be sharing the rough cuts. Michael weiss and ambassador pickering, thank you very much. Later this hour, were going to get an unique view on it from new York Police Commissioner bill bratton. He understands capabilities very well. What does he make of isis capabilities to do this. Alisyn. Chris, to latest in the president ial reelection. Donald trump on top in the latest Fox News National poll. Backed by 26 of republican voters. Dr. Ben carson, three points behind. And marco rubio surging into a tie for third place with ted cruz, as you can see there. This as rubio fighting allegations about his personal expenses. Cnn chief Political Correspondent dana bash is on the campaign trail this morning in concord, New Hampshire. Dana, what have you learned . Reporter good morning, alisyn. Well, youre talking about that new fox poll. I think whats most interesting about it, as we put it up on the screen, the numbers now but how much they are virtually unchanged when you look at the very top in the last month. Donald trump, as awe said is now at 26 . He was at 24 in october. Carson 23 now. 23 in october. And you go down the line, still, everybody else is really far behind. But when youre talking about where i am now, New Hampshire, marco rubio is the man who everybody is looking at. Because in the polls here, he is really jumped since his debate performance last week. Or a couple of weeks ago. And thats probably why donald trump is going after him. I spoke to i asked trump about that, and i asked rubio who is also here in New Hampshire to respond. Listen to this. Marco rubio has a disaster on his finances. He has a disaster on his credit cards. Bottom line, people need to you understand, this is an American Express card. There were personal expenses on there. I paid them directly to American Express at the time. Reporter at issue there, michaela, is the questions about which two newspapers in florida reported on yesterday. Renewed yeses about a credit card that rubio used when he was in the Florida State house. It was a Republican Party credit card. He paid some personal expenses on it. He insists that he paid them. He didnt just charge the party for things that he was doing personally. They say in the Rubio Campaign that they are going to make that public to prove that he did nothing wrong. They wont say when thats going to happen but they say its go to be soon. Donald trump stirring the pot and other candidates have to respond. Dana, thank you for that. Breaking overnight the New York Times is saying george h. W. Bush quoting two in his new biography. John bermen is here. Michaela, george h. W. Bush saying cheney used too much influence forcing for force. Bush says of dick cheney, he was just ironass. His seeming knuckling under to the real hardcharging guys who want to fight about everything. Use force to get our way in the middle east. Also the elder bush goes after his defense secretary donald rumsfeld, calling him an arrogant fellow who served badly. Hes more kick ass and take names, take numbers. And george w. Bush responded. According to the the New York Times he says, quote, i disagree with his characterization of what was going on. I made the decisions. This was my philosophy. As for the former Vice President dick cheney, he responded on fox news. I think we have that. Well play that. I fully admit that, after 9 11, i saw my role as being this tough and aggressive as it need to be to carry out the president s policy. 43s policy, to make sure we didnt get hit again. You know whats interesting, dick cheney was george h. W. Bushs defense secretary. Theyve had a Good Relationship over time. Donald rumsfeld and george h. W. Bush not so much. A rivalry that dates back. Not so much. Theres plenty of blame to go around. Theres plenty of finger pointing after the george w. Bush administration. Its one to another. But father and son. Thats interesting. Because the president takes one position, thats why you have other people, to minute the finger for you. There you go. More president ial politics. Dr. Ben carson said he was not always the softspoken and low key man weve seen on the campaign trail. In fact, he said he has a violent past. He said he attacked classmates and his money. When do his classmates remember about his violent temperature . We have a cnn investigation. Carsons past next. The year of spieth comes to a close. Tour championship winner. And he does indeed take it all. Gegiving up all the thingsan she loves to do. It should just mean, well, finding new ways to do them.

Prepare for challenges specific to your business by working with trusted advisors who help turn obstacles into opportunities. Experience the power of being understood. Rsm. Audit, tax and consulting for the middle market. He is meek and mild on the stump and on the debate stage. But gop candidate ben carson says he wasnt always so softspoken. In fact, he says his past was riddled with violence. We spoke with folks he knew growing. Up cnn joe johns has that for us. Reporter ben carsons quiet, dignified approach is a big part of his appeal. But he says his calm demeanor was carved out of a violent past. As a teenager, i would go out and hit people with rocks and bricks and baseball balls and hammers. Reporter carson wrote in his book about striking a school mate with a combination lock. Nearly punching his mother. Carson said he also tried to kill a friend identified as bob with a disagreement over the radio. He describes his temperament as pathological and a disease that made him totally irrational. I had a large knife, fortunately under his clothing, he had on a large metal belt bu buckle. And the knife struck with such force that it broke. Reporter in fact, carson, its depicted in a movie. What did you do . Reporter but then an epiphany. Carson said he quelled his anger with prayer. I locked myself in the bathroom. And started contemplating my life. And realized id never realize my dream of becoming a physician with a temper like that. Reporter from that day forward, carson said he was a man from poverty in detroit to world famous neurosurgeon. I never had an angry outburst since that day. Reporter but that early picture of violence is not recognizable to someone who grew up as carson. I was shocked. I was surprised. He was quiet and calm. Reporter cnn reporters maeve reston tracked down neighbors. Only one said they heard vague rumors about all of the incidents. But all said this was not the boy they knew. I was surprised when he said he tried to stab someone. I was like, what . Reporter does it sit with the guy you knew, that kind of activity . No. Reporter and telling cnn, it was a quote, witch hunt. Cnn has been had unable to locate witnesses or victims. I associate him with a lot of things, but never stooping to the level of a street thug. I was a little surprised by it. Reporter tith miami mcdaniels said he was one of carsons closest friends. He said he raised it with carson after the book came out. He said, you hid it from us . He said he was too embarrassed to even talk about it. I was surprised about some of the things he said, he said it honestly and i believe everything he said. Reporter joe johns, cnn, washington. Lets bring in Cnn International reporter maeve reston. Shes been investigating carsons story for more than a month. Lets also bring back dana brash. Maeve, tell us this investigation. Carson said he had this pathological violence and what his childhood friends say . Well, we went out to find these people in detroit. We went through the yearbooks. We called many of his classmates. I found his Close Friends through every period of his life. And the person he describes in the anecdotes on the campaign trail as leading up to this religious epiphany that he had cannot remember any episodes of violence involving dr. Carson. They describe him as meek, quiet. Someone who would never defy his mothers orders to cross the street. So its really just raised a lot of questions about these stories. We are still are looking for this jerry and bob that he describes. But weve contacted all of the jerries and bobs that we could in his class. And still have not been able to find anyone who is part of these incidents or was involved in them. And we have not been able to find any eyewitnesses to them. Maeve, respect the gum shoeing, but if we might. Let me go to dana bash. Dana, this is a story hes been telling for a long time, before he had any president ial aspirations, why would you want to predict yourself as a thug, if you were in his situation . And why would you expect people who now have to deal some ownership of his success to throw him under the bus . Well, if you listen to the way he describes his story, its not just that he was a thug. He talks about the fact that he was a kid with issues that he, you know, he got over. Its part of the story that he tells on how to explain what it was like for him in the innercity. As he calls it the mean streets of detroit. And how he got from there to where he is now. So, i think thats certainly the answer to that question about why. Maeves reporting actually there in detroit with his classmates, with his friends and people who knew him, you know, obviously, tell a different story. But it still leaves a question mark at the end of the story looking for the people which i think is fascinating. So, maeve, it doesnt mean that it didnt happen. It just means that you cant find anybody who was connected to him that remembers this side of him. I mean, whats your takeaway, after youve done all of these interviews with people in the past . Well, i think it raises a lot of questions about the stories that hes told. And why his campaign wont put forward the people that he says were involved. In these incidents. The other important point is that this is at the crux of his appeal to evangelical voters. This violent, angry, pathological temper. He said he went into a bathroom and prayed for many hours. And spoke to god directly and that god intervenes and essentially you know, helped hi
