In atlanta, welcome to our viewers here in the United States and around the world. Im George Howell, cnn newsroom starts right now. As we mentioned, it has been three days since the disappearance of egypt air flight 804 and searches have not yielded results. Hardly anything have turned up. Personal belongings made up mostly of debris so far along with some human remains. The most important piece of the puzzle is the socalled black boxes. They should be able to give investigators the cockpit voice recordings and data, the flight data that is so important. Both of these could offer a breakthrough this explaining what exactly happened. For the latest, lets bring in ian lee following develops live in cairo this hour. Ian, obviously egypt is the lead on this investigation. What do we know about their focus today . Reporter again, george, the main focus as it has been is going after as you said these flight recorders, trying to find out what was going on on that plane in the final moments, what was being said in the cockpit and in the cabin. And what were the instruments saying. Now, we do know a bit from the a acar system which indicated there was some smoke, but that leaves a bunch more questions about what was actually happening, was there actually smoke or was there other things that tripped those sensors. So really these flight recorders will be so crucial in terming what exactly happened. But they will also be looking for the cabin, the main part of the plane to see if it shows any signs of what happened, was there an explosion on board, what possibly could they learn from that. And right now we do have parts of the aircraft which include carpet, it looks like a blanket, a life vest, a pillow, as well as some personal belongings and body parts. But it really will be these other larger parts and these data recorders that will give investigators really insight into what happened. As we wait for these investigators to hopefully turn up more pieces to this puzzle, to find out exactly what happened to this plane, there are families that are obviously waiting for answers. What you can tell us about these families, how they are dealing with all of the uncertainty just not knowing what happened to this plane . Reporter thats right. And 66 people lost their lives on this flight. Roughly a dozen nationalities. The majority of them are egyptian. And egypt here is a country in mourning. Weve been talking with the family members after this tragedy, they are trying to remember their loved ones in life and not so much focusing on their deaths. But today there will be funerals for a lot of them around the country, people will be gathering to pay their respects and pray for their lost ones even though the bodies havent been recovered. They will hold these funerals to pray for the dead which is customary here in egypt. And when these bodies are recovered, which egyptian officials telling families yesterday it could be weeks once after theyre found because they do need to do dna testing to make sure the right body gets to the correct loved one. And then they will have the burial. But today really is egypt is still in this state of mourning. We will be at these funerals to hear more about these loved ones and who they were. Cnn International Correspondent epll ian lee arri live for us in cairo. Now we bring in managing director the a airline ratings. Com. Jeffrey, always good to have you with us. I want to focus in on what we know at this point. We know about the acar data. What could this possibly tell us . Yes, the acar data is really giving us some clues that there was a catastrophic event that brought this aircraft down. The exact cause is really just speculation at this stage. Although whatever it was, it was major and it was catastrophic. So one would have to draw from that a conclusion that it was an explosive device of some kind that blew out cockpit windows, causes the avionics bag in the lavatory to have a fire, set off alarms. And this all happened within two minutes. So its not something that was under control, it was completely out of control. And therefore the plane has been lost. It then spiralled down out of control and impacted the ocean and clearly from the debris we have seen that was a fairly Significant Impact and total loss of life. And were looking at some of that debris that was recovered. The search continues and the focus is to find the fuselage and flight data recorders. Jeffrey, how important are those pieces to this puzzle . Theyre absolutely critical. There have been a few reports that the black boxes have been located, but the egyptian authorities have it is missed those and said theyre incorrect. Finding these black boxes is imperative. Its going to be a challenge because its 3,000 meters deep. They have to get the right equipment into position and then once they have located them through their team, which lasts about 30 days, they then have to recover them. Now, it took us putting this in context with air france 447 which was lost in 2009, same thing. We had debris field on the ocean surface, it took them two year it is to locate the plaqblack b and fuselage. So we should not yupd estimaund the challenge in front of us because this airplane is lying at exactly the the same depth, 3,000 meter ares. So its a very, very Challenging Mission in front of those rescue teams. But making the obvious comparison here, when you look at like an mh 370 search for instance, you didnt have the oil slick that was identified on satellite and obviously investigators werent able to find the debris that theyre finding in this case. So tease are very different searches i would surprise amise this is a little more focused. There are a lot more resources obviously. Mediterranean, a lot of countries will be involved, its far more successable as far as getting to the location. Even air france, its a fairway from anywhere where has mh 370, same thing, a long coast from the western australia, 2,000 kilomet kilometers. So vastly different challenges between those three crashes. This one, and i hate to use the word easier, will be somewhat easier, but nothing is easy about this. This is very, very challenging. And hopefully we can have a significant find a lot sooner than we did with air france 447 which was two years. Jeffrey thoch mas live for u via skype. Thank you for your insight. As this Investigation Continues and crews scour the mediterranean looking for wreckage amend also recovering human remains, families of those on board are saying can goodbye. Family of a Flight Attendant gathered saturday in cairo for a Memorial Service remembering the 25yearold and they dressed about in white rather than dressing in the traditional black. Translator she loved going out, she loved her friends, she loved her family. She was very adventurous and she really loved her work. It is such a shock for everyone. She was young, shes never been married, but i accept this is gods fate. Translator we did everything together. I just cant believe this. I dont even know what to say about her. I feel like im in a dream. She loved her work. We would always travel together. We went everywhere together. These families are dealing with such grief. The investigation and search continues in the mediterranean and Cnns Becky Anderson sat down with egypts foreign minister, he stretched how crucial it is to locate these black boxes as theyre called and how egypt is relying on their International Partners in this investigation. Listen. There have been claims of smoke in the cabin before it crashed. What do you know about those claims and how might that inform the investigation . Im sure its being verified that the technical people are looking into it. Im not certain that it can be conclusive in any determination one way or another, but it is certainly an important element in a jigsaw puzzle that has to be fully compiled. So the investigation will take this into account and evaluate it accordingly. There are a rot of a scenarios in response to what you are hearing and meaning. I think we should all be careful. There are some that are farfetched and only pure speculation. Those are it is cdisconcerting. And of course we will continue to cover this investigation and the search. Other news, u. S.

So saturday the democratic frontrunner accused trump of pandering to the gun lobby. She was speaking at an event put on by the Trayvon Martin foundation. That organization is named in honor of the africanamerican teen who was killed in a fatal shooting. Trump has claimed clinton wants to abolish gun rights. Enough is enough. Unlike donald trump, i will not pander to the gun lobby and we will not be silenced. And we will not be intimidated as long as children anywhere are being killed by gun violence, we will keep fighting for our kids because they deserve a president who stands up for them and stands with the mothers here. Their lives are valuable. P. Clinton there talking about donald trump, but still competing in the democratic side of things, she has a nearly insur moiptable lead in the race for her partys nomination, but fellow democrat Bernie Sanders is still on the hunt. He spoke at an event in new mexico on saturday ahead of it that states primary next month. Sanders is facing accusations that hes dividing the party at a time that it needs to unite against donald trump. But he promises that democrats are will prevail over the republican frontrunner. Listen. Donald trump will never be elected president because the American People will not support a candidate who insults mexicans and latinos, who insults muslims or women, who insults africanamericans or veterans. Our job is tobly our people together to create a government that works for all of us, not just the 1 . And we will never allow people to divide us up. Clinton leads sanders not just in the primary popular votes, but also in superdelegates. Sanders has pledged to continue his campaign all the way to the Democratic National convention. Theoretical theoretically, he even has a chance to win there, but as tom foreman explains, the super delegates give clinton an edge. Take a number at what they must get to clinch at the convention and look how theyre dividing the pledged delegates so far. These are the delegates who must vote this way at the convention because thats how their states voted. And there are about 800 o outstanding in the remaining since states plus puerto rico and district of columbia a. He could catch her if he wins 70 of what is left, that is outperforming of what hes done so far. But these people could get in his way. The super delegates. What are they and how are they so powerful . Lets start with some math. Lets say we have horn 20 Million People who have voted so far in democratic primaries and at this point we have this many pledged delegates out here. Divide them and what youre able to say is that each delegate represents about 7,000 actual votes by actual people. Superdelegates have just as much power, but they are not accountable to the vote of the people. They get to vote as they please. And right now theyre dividing decidedly in Hillary Clintons favor. Bernie sanders has only 42 saying they will back him at the convention, she has 522. Why such a disparity . It has to with with the makeup of the superdelegates themselves. These are largely members of the Democratic National committee, they are big elected democrats like governors and senators, and they are party leaders. In other words, this is mainly the part i establishment. They were put in place back in the 1980s specifically to make sure that there was no populist movement that would saddle the part theity with a candidate that the party didnt necessarily want. And right now, the superdelegates are showing very little interest in helping Bernie Sanders get this nomination. Tom foreman there explaining superdelegates and how they will factor into this. Donald trump is making an appeal to latino evangelicals. He recorded this message for more than 1200 latinos attending the National Hispanic christian leadership conference. Listen. Were going to do massive tax cuts especially for the middle class and people that are poor are going to pay nothing. Theyre struggling, its tough, and under my plan which is filed at donald j. Trump. Com, you will see its nothing, absolutely nothing. Youre going to get it, well bring back jobs, you will start paying taxes after youre making a lot of money and hopefully that will be soon. Were going to stop drugs from pouring into our country. Were going to strengthen our borders. People will come into our country, but they will come in through a process, they will come in legally, but we will stop the drugs. I want to thank all the groups and Committee Takes as that ask this. National hispanic christian. Three great words. There are been many questions surrounding trumps wealth. Cnn money looked into his latest federal Financial Disclosure form to find somene answers, bu it is difficult to assess just how much donald trump is worth. Reporter its Donald Trumps pitch to the American People. I biuilt a fortune for myself ad i can do it for the country. You see the wine. Ive done great. And thats the kind of thinking you will need. Reporter just how great has trump done . Financial disclosures hes filed with the federal Election Commission may be long, but theyre short on specifics. The form stndoesnt call for great deal of detail. It allows you to report ranges of income rather than exact amounts which is a little different than a tax return that you might file with the irs. Reporter but the government doesnt require trump to release his tax records. The long Disclosure Document is the only official window into trumps wealth. The most recent filing was assets of at least 1. 4 billion from january 2015 through may of 2016, excluding investmentinves includes at least 611 million of income according to our sally. But items hard to tell whether that income is actually flowing in to trumps pockets or into his companys coffers. It lists revenues rather than income. He has for example for his golf courses golfrelated rev neenue. So it makes it difficult to know, is that just the Gross Revenue of his golf course or is that actually the income to donald trump after he pays august the expenses in running the golf course. Reporter in the end the distinct may not matter, at least not to the government. The disclosure form is supposed to find potential conflicts of interest, its not a check on the candidates math. And trumps math has always been hard to verify says author tim obrien. Trump sued him kraming oclaimin low balled his net worth. The case was dismissed. He always has some humongous figure for goodwill and branding. He says the trump bland is worth a many billions and thats just donald sit being around eating a cheeseburger saying im worth x. Reporter trump claims a net worth in excess of 10 billion. Forbes and wealth x put it closer to 4 billion. We reached out to the Trump Campaign, but didnt get a comments. Short of an independent audit, all we really know for sure is this. Im really rich. Reporter cnn money. The u. S. President barack obama is scheduled to arrive in vietnam in about nine hours time.
