And keir simmons is live at amman, jordan. And how do we know it is a Jordanian Air strike and the u. S. Saying they still cannot verify that fact . Reporter well, i think it is extremely difficult to verify because nbc news understands from a senior u. S. Official that the family learned that she had died because they were sent a photograph of her and that indicates that she did those pictures arent inconsistent with traumatic injuries. But of course it is very difficult from a photograph to be more specific than that. The family once they got that corroboration, issued a statement describing themselves as you can imagine, as heartbroken, talking about the incredible work that kayla was doing, going to help Syrian Refugees in turkey and then in syria. And they actually released a letter that kayla had smuggled out to them from her captivity by isis. And just to read a few excerpts from that because it gives you a picture of what kind of young woman she was. She says in that letter i have a lot of fight left inside me. Im not breaking down. And i will not give in no matter how long it takes. She also goes on to say i wrote a song some months ago and it says the part of me that pains the most also gets me out of bed. Without your hope there would be nothing left. Sher talking to her family. And she goes on aka, the thought of your main is the source of my own. Simultaneously the hope of our renewed union is the source of my strength. It is so painful to read that knowing what happened to her. Just to go back to your earlier question there, joy. I mean what isis claimed is that she died in a bombing by the Jordanian Air force here. But as you say, the jordanians backing up what they say about u. S. Officials, they dont believe they carried out a bombing in the area where kayla was. And if you could just zero in on Public Opinion there in jordanian, keir. We know that after the death on video of the jordanian pilot, there was just fury in jordan and then the ratcheting up of the strikes and has this ramped up and what is the state of the opinion there regarding the coalition . Reporter well, i think it will compound the sense of pain. And they are still mourning the death of their pilot and that was a very very important moment here because of the horrendous way he was killed by isis. It has enraged people and pulled the public back behind these airstrikes, at least for now. It is something of a turning point, as far as we can tell that point, joy. Nbcs keir simmons, thank you very much. Reporting in amman. And the cyber caliphate claims allegiance with isis hacked into the twitter account of news week. They said the account was hijacked for 14 minutes an during that time they changed the accounts header and tweeted offensive messages to Michelle Obama and the first familiar. And lets to laithal cowery. And whether they call themselves the cyber caliphate, and whether they believe they have any actual links to isis. So far we dont believe it has actual official allegiance or affiliation with isis. It appears that it is run by supporters who have some hacking skills. It doesnt appear the hacking skills are advanced, but at this point we can only see that it supports isis and it is a view of part of the ever expanding caliphate and it has launched a few attacks in the past couple of months targeting western and proshia websites but again it doesnt seem to be highly sophisticated. And lets talk about now we do have this confirmation that Kayla Mueller has been killed still a lot of disbelief including the government of jordan, that it was the jordanians at fault for her death by isis. In terms of analyzing isis behavior up until now, why wouldnt they just claim it because they have not been shy of murderous acts in the past why are they trying to put this off on the jordanians. This happened after the jordanian government vowed to strengthening the resolve against the strauk state. They said we had a lot of airstrikes but not in racka where is where they say she was killed. But they dont differentiate between coalition and Syrian Regime aircraft. It is really trying to create a mistrust between the jordanian and the u. S. Government to show this u. S. Led coalition is not coordinated enough and it lacks management and it does not have a clear sight of what is going on. Thank you very much lathal cowery. Confirmation of Kayla Mueller death comes as washington is on the verge of the first congressional war vote in 13 years. Right now members of congress are awaiting a blue print from president obama outlining his request for authorization to use military force in the fight against isis. Chris jansing is the nbc senior white house correspondent. What do we know about the timing and the details coming from the white house . Reporter we think it will come soon as soon as tomorrow. It has been worked on since january. He worked with a Bipartisan Group in congress and since then there has been almost an unprecedented out reach to the hill not just by the congress and including those in his administration, including john kerry and susan rice. What are we looking for in the language . That is the sticky point. What does it say from boots on the ground, and nancy pelosi said that is a nonstarter and the hawks on the right saying they need to have it openended to put boots on the ground. And the timing it has been 13 years and we are still using that authorization for war to fight against isis. And so it is looking like it will be something that is timecontrolled. And the third issue is geography. Will it cover just iraq and syria . It will go to the Senate ForeignRelations Committee first and the chairman bob corker said he will start hearings very quickly once he gets that wording. And chris, very quickly, you said and mentioned this unprecedented out reach from the white house to the hill where does the white house expect the resistance to come from the Democratic Party or the typical scenario of mistrust by republicans of this white house and its attempts to use its powers . I dont think there is anything typical about this. What we know is everybody wants to there seems to be an overwhelming need an desire to get this done. There is no doubt they want to show support on the war against isis but i dont think you can draw any line as long party lines in terms of the three main areas of convention and weve seen contention and support from both sides and we have not gotten a clear read from the president on where he comes down on this and they will send over a working document somewhere in the middle that they think can lead to compromise joy. A lot of blurred lines. Chris jansing, appreciate it. Sure. And coming up Ayman Mohyeldin says what Kayla Muellers death says about how difficult it is in syria and the potential for clat cal damage. And people in boston are once again digging out from mounds of snow. The latest snowstorm has led the city to a new record. 77. 3 inches. And with so much snow some communities are getting permission to dump it no the ocean and other bodies of water. Just to give you an idea of how much has been cleared across the state so far, it is enough to fill gillette stadium, home of the super bowlwinning new England Patriots 90 times over. The storm has also provided a boost to some boston businesses like those who sell out snow blowing machines. One business has seen business of over 100,000 dollars. And here is Charlie Baker about the subway systems. I know people at the d. Have been working for the past two weeks to keep the system up as much as possible and i would include the general manager and my commentator on that and we are going to have to figure out and they are going to have to figure out what the operating plan is Going Forward here. Amanda sack yuma is live and what is the state of the Transit System in that city and is it still at a complete halt . Reporter hi joy. Large swaths have been at a stand still since Public Transit has stopped yesterday. And after it abruptly ended yesterday at 7 00 p. M. And leave major league stranded and causing some to take hours to get to their destinations. The calls to the city have sky rocketed and a petition has been floating around for residents to sign calling on greater Reliable Service through the ttransit conditions regardless of conditions. The Transit Authority general manager had a press conference where he acknowledged the frustrations but still unable to say whether this is the end to these very severe disruptions to Public Transit. Meanwhile authorities are trying to clear out the snow as fast as they can before the more bouts of snow come down later this week. There are two additional snow melting machines that should be coming soon just like the ones here at this snow cart. So we should be seeing authorities getting ready for the next round to come. Msnbc Amanda Sakuma thank you so much. And we are expecting an update from the boston mayor at 3 00 p. M. Eastern time. The suspect in the death of missing virginia student Hannah Graham has been charged with firstdegree murder. Virginia authorities made the announcement at a press conference this morning. Graham, youll recall disappeared last september triggering a massive search that ended when her remains were found five weeks later. Peter alexander is in charlottesville, virginia with more. Reporter joy, good day. The firstdegree murder charge carries with it up to life in prison and the prosecutors, the district attorney, say they are not pursuing capital murder which could carry with it the death penalty. Her family was not in attendance today and the investigators would not detail the evidence they have linking grahams death to Jesse Matthew. They also wouldnt say whether any deal had been made between the defendant and prosecutors in this case. Matthew has also been charged in the 2005 attempted murder of a 26yearold young woman. He has pled not guilty to all of those charges. That case has forensic evidence linking it to the 2009 murder of a young woman named morgan harrington, a student at Virginia Tech university who had, at the time been here in charlottesville in the area for a rock concert but disappeared and her body under similar circumstances to that of Hannah Graham was found many miles away basically deposited in a field. The next time that Jesse Matthew jr. Will be in court is next wednesday. That is his first court appearance. Prosecutors say they are confident they have the evidence they need to pursue this case. That is the latest from charlottesville, joy. Back to you. Peter alexander, thanks.

A Senate Committee held the first hearing on childhood vaccinations today. Officials from cdc are testifying about the link between vaccination and the Measles Outbreak. Is there any scientific that vaccines cause autism . No. Is there any question that it cause profound mental disorders . No. But some diseases can. New numbers shows the Measles Outbreak continues to grow here in the u. S. The cdc said there are now 121 cases in 17 states. And then there is this. A report on think progress. Com finds some california parents are considering throwing measles parties. They are quote, social gathering where unvaccinated kids can come and build up a resistance to the disease. And joining me now, Alexander Van tellen who works at fordham university. And doctor my mind is officially blown by the notion that people would expose their children to something as deadly as the measles in order to raise immunity. Is there any logic in doing that . It is a very interesting thing. I would say first of all, do not take your kids to a Measles Party. There is a long tradition for this. Going back to chicken pox. Prior to the vaccine being developed, it did make sense to expose your kids early rather than getting it later in life but with mono when you are an adult, it could wipe out years or months of a life. And now that we have a vaccine for measles, there is no need for doing that. Before the 1960s, we had about 500 deaths every year and 50,000 people hospitalized 4,000 people getting serious brain diseases as a result and that is why we have the vaccine and that is what you dont want to expose your kids to. And if you have an infant in the Measles Party for elementary age kids this is introducing the possibility of death. It is a deadly disease. Not only infants but kids with immunosuppression. We dont know kids with immunosuppression and kids with cancer, and we heard about the story with the child that could not have the vaccine and she has now been exposed. And then getting it with the mumps and the rub ella rubella vaccine. Idaho has been warning about the mumps outbreak at the university of idaho. 21 reports possible cases, including six no the boise area and as of february 6th two cases in the moscow area. Do we have to worry about that too . It is. It is easier to catch, and the vaccines go together and there is a good reason to vaccine against all of those. Mumps is difficult as an adult male, it could cause impotence and as a pregnant female. I think we are failing to engage and understand and community about the vaccine. And hopefully some friends were listening and can pass this on. Thank you dr. Alexander van actual ken.
