Time the russian passenger jet on its way from egyptian resort to st. Petersburg, russia, plummeted to earth, killing all 224 people on board. Experts say the flash is significant, but by itself does not prove or disproved claims this was a terror attack. For the latest on the investigation, lets bring in cnns ian lee in cairo. Ian, what is the shape of the investigation . So many players involved. Reporter thats right. If we look at all of the different people involved, we have a team from france and germany and ireland here helping the egyptians. You have the russians involved. They are looking right now at the black boxes trying to determine what they can say about the final moments of this flight and what can lead to this. Right now, we are hearing from officials. They are still saying that this was a mechanical issue. They have not ruled out terrorism, but they are downplaying it right now. This despite metrojet doesnt believe a mechanical issue could cause the plane to go down. We are looking at the heat signature that was detected over the sinai peninsula. That could have been a number of things. A number of theories are brought up now. Potential missile which is the most unlikely as isis is not known to possess the abilities to have that missile to hit a plane traveling over 30,000 feet. You have a potential for a bomb exploding. Officials on the ground investigating have not detected any residue that leads to that. There is still a lot more wreckage to go through. There is an engine that could have exploded due to a mechanical issue or it could have been the plane hitting the ground which when you look at the video of the wreckage, you do see the scarred parts of the plane. This does open a lot more theories, which investigators are going to go through. Many of the bodies of those who died in the crash have been returned to russia. Officials are also looking at the bodies for clues to the crash. Right now, russian officials and egyptian officials urging people not to jump to conclusions about what caused this plane to go down. Ian lee for us in cairo. Thank you. Overnight, a second plane carrying human remains from the crash arrived in russia. A medical source in the sinai tells cnn that most of the bodies retrieved from the wreckage are in tact and show no signs of burns. President putin describing it as enormous tragedy and his thoughts are with the families of the victims. In st. Petersburg for us is diplomatic editor Nic Robertson. So many grieving for their loved ones killed in the crash. Are they reacting at all about the speculation of what may have brought the plane down . Reporter well, we are just had a reaction on that from president putins spokesperson. He said very clearly now that there is no link to terrorism. He says there is unwarranted and unneeded and inappropriate speculation drawing any connection with russias actions in syria and downing of this flight. It seems coming from the very top now they are trying to put an end to the notion this could be an act of terrorism. What he does go on to say this needs to be fully and properly investigated and everyone should hold back on the speculation until the investigation is complete. That is the message here. At the same time, the families are not far from the airport and visiting a morgue. 196 bodies now returned. Another 52 of those arrived on a flight early this morning. It is a slow and very, very difficult process for the families to go and view the remains and discover if their relatives are among them. What we know so far, nine people identified. Two children. Both girls. A 10yearold and 14yearold. We have been told by authorities, as early as today, the families may be able to take their loved ones home for burial once they are identified and once the relevant paper work is completed. Alison. Nic, you hear the stories of who actually was on board and it is heart breaking. Nic robertson, thanks so much. This morning, republican president ial candidates with a united front and control of future debates is falling apart. This as a pair of polls paint a confusing picture of the gop race. Surprise, surprise. Cnns sara murray has the latest from washington, d. C. Reporter good morning, alison and miguel. It is not donald trump leading nationwide anymore. Ben carson is the frontrunner in the nbc news poll. He leads 29 to Donald Trumps 23 . Trump still has bragging rights. He leads in a poll in new hampshire. He is ahead of ben carson by ten points. If these polls sound chaotic to you, it is nothing compared to what is going on with the Republican Debate process. After all those campaigns got together and huddled in a room and agreed to debate rules requiring Opening Statements and how cool it had to be in the debate arenas. Now it seems that is falling apart. It all started when Donald TrumpsCampaign Said he will negotiate directly with the networks. After that, kasich said he would not sign on a letter with other candidates regarding the debates. Chris christie followed suit and Carly Fiorina jumped ship. It was a short lived truce. Alison and miguel. If there was a truce, lets get more now from the president ial campaign with cnn politics Jeremy Diamond is with us. Good morning to you. This was really short lived where you saw some comradery half, but it crumbled over the debates. Absolutely. These are republican candidates. The idea they would somehow unionize and hold united front was far fetched. For sure, we are seeing they did gather together on sunday and have the effort to come together on the debate process. Ultimately, they realized they could have gotten into something nasty and messy by trying to wrestle control of the debates from the rnc and tv networks. Jeremy, the polls are all over the place. National polls show ben carson on top. He is gaining in iowa, if not ahead in iowa of mr. Trump. The monmouth poll now shows that trump is doing well in new hampshire. Can we divine anything from these tea leaves . The wall street journal nbc news poll was conducted last week. It was conducted mostly before the last president ial debate. Only one day of the polling was done after the debate. I think this is pretty similar to what we saw with the New York Times cbs poll that came out last monday. We are having a similar feeling there. That is from last week. Who knows how much of an impact the debate will have. It is hard to tell. It is clear that last week before the debate, ben carson was surging ahead of donald trump. Whether carson will maintain that lead in the post debate weeks to come, that still remains to be seen. We have donald trump coming out with his new book today. Timing could not be better. In it, i know you thumbed through it. He is focusing on the dissolution of the direction of where america is going. I like in chapter two. He really had quips. How boring can i possibly be. Some of this is entertaining. You look at the book as a whole, can we glean anything from it as to what kind of President Donald Trump could be . I have been covering Donald Trumps campaign for the last several months. I certainly did not learn anything new from the book which i looked through last night. There are certainly things that come across. Most of it is a regurgitation of the Campaign Speeches and policy platforms. He tries to show a more personal side, i think. You see that coming across with quips throughout the book. He talks about his personality and a bit about his family. Maybe trying to soften his image. He tries to blunt the past criticism he had to deal with. Specifically on immigration. In one chapter, he talks about immigration and how he loves immigrants and how undocumented immigrants come into the country do so for good reasons. That is interesting. He criticized jeb bush for saying undocumented immigrants come to this country out of an act of love. Trump appears to be agreeing with that. The vast majority are not rapists and criminals like he first appeared to suggest. Instead, saying most of them are here for the right reasons. The other thing about the book, it appears to be a way for donald trump to position himself with conservative voters and explain himself for being a democrat before and borrowing money from his father and supporting health care. All of these things is a problem for him from the right. Absolutely. You see him explain there is a section where he goes im a conservative. He explains he was once a registered democrat. He explains as i always have been a conservative republican inside. I guess what he says is he has conservative values. He does try to explain away that criticism. He says i dont think Single Payer Health care works for this country, but in scotland, it is great. Thats hilarious. We will see how many people get out and buy it and read it and feel closer to voting for him. Jeremy, thank you for your you analysis. President obama giving excons a Second Chance.

Reporter the prisoners serving harsh sentences, the president wants the government to not hold their past crimes against them.
