The cathedral of notre dame still stands but without its elegant spire. Bun burned away. Suddenly you feel your mother has been hurt by the fire. While an investigation is going, officials are calling the blaze unintentional. They suspect it started around 6 30 monday night amongst scaffolding at the base of the spire. The flames spread quickly across the medieval roof, made of so many timbers it was nicknamed the forest. The heat kept building and rising until oh, my gosh the steeple just fell inside the church. The spire came crashing down into the churchs interior, fanning the flames. For hours that felt like days, it seemed like notre dame, our lady of paris, might be lost. French officials telling the nation to brace that she may not be saved. And that the gothic masterpiece visited by 13 million every year and full of priceless art and sacred relics would be reduced to ash. Around 400 firefighters contained the flames, enough to go inside and saw this. The interior badly damaged, but not a charred shell. Firefighters announced they managed to save the structure. Notre dame would survive. And they said major art and relics, including the holy crown of thousands, were saved. Parisians came out to sing hymns for their beloved cathedral and praise the firefighters. The french president telling the nation the worst has been avoided. Notre dame will be rebuilt because it is what the french expect and what their history deserves. Parisians have vowed to restore notre dame. Donations pouring in. Two of frances richest families have pledged some 340 million, a leading european architect said repairing notre dame could take decades. With me now, chris jansing. She knows this city very well. And lets start with you. Lets talk about what were seeing right now. Weve seen these workers atop the right tower there. What more do we know about the efforts thats been undertaken right now . Its dangerous work. Its necessary work. Theres two urgent needs. Even as the city is still in mourning, theyre trying to come to grips with the emotion. They know the engineers, they have got to get inside and see where the danger is, just how secure is what it is Still Standing of this building. 100 firefighters on standby. Theyre concerned that in these centuries old timbers there may be a little bit of ember thats going on. Theyre concerned about the possibility of another fire starting. Theyre also concerned about the possibility that some of the stones that have been charred could crumble. The number one thing right now is to assess and make sure they can get safe access for the engineers to go in. We watched it yesterday, two thirds of this roof is gone. It had those huge trusses made of that ancient wood from the middle ages. So much of that gone. They need to figure out a way to get at least a treemporary roof. What they dont want to do for the pieces of art that remain, the fixtures from centuries ago that remain, they want to protect them from the elements. Lets talk about with which the speed of the french people have stepped up. Many are surprised theyve been able to raise so much money so quickly. Are you surprised . Were talking about a monument here thats not just iconically religiously culturally or even architecturally to france. Of course, across the globe. This is a building thats been standing for over eight centuries. Its survived two world wars. Its survived the revolution and here we are with one fire its essentially lost most of its roof. Its lost its iconic spire. Frankly, yesterday i was here within an hour of hearing that the fire had started. As we see here today, craig, hundreds and hundreds of people have flocked to the site. They were transfixed on this, some shedding a tear. Parisians singing ava maria. Were talking about a country coming together because are saying theyve lost a family member. When i walked up this morning when we arrived and i saw the spire was gone, it hit me. To my emotional core. Its so iconic of paris and of europe. A number of artifacts saved them, among them the crown of thorns. I mean that was one of the main things people were concerned about. We were both here at the bataclan attacks. One of the heroes was the chaplain of the firefighters. It was him with another group of actual firefighters, he insisted on going in and making sure that that beautiful relic, which holds a little piece of what is believed to be the original crown that christ wore on good friday when he was crucified was saved. They dont know 100 about the rose windows. Another iconic piece of this structure. Theyre going to assess them. It looks like they are intact. Theres a tunic from a 15th century french king, st. Louis. What they dont know, there are things that are bolted to the walls, painted there. They need to make sure that that is stable so they can get that in. Theyre taking some of that stuff to the louvre, which every major museum of that stature has a major restoration, but theyre going to need help. People from the United States to russia have offered to help. There are other pieces that are being secured by the ministry of culture. Theyre going to need some time to assess everything and the condition that its in. Again, like the building, this could be years, even decades of restoration. And as you mentioned, this is such an important effort even that unesco has declared support of the french government. The official came out and said well stand by the french government to restore this iconic building. Its a World Heritage site. This is standing at the back of the cathedral, the cross, the golden cross. A lot of people are saying a sign of resurrection, which is what they hope for the building. We saw the picture from reuters, the smoke, the ash. Theres the picture. Way to go control room. The picture from reuters on the right side of your screen. A little bit more than symbolic. So Many Americans know notre dame as perhaps the preeminent tourist attraction in this country. Some 13 Million People come every year. But give us some historic perspective. It is so much more than that. Thats why france has come together on this day and theyve united. Actually youre hearing from different sectors of society. Its not just about those who go to the church. Weve had statements from the American Jewish community saying this isnt just a symbolic importance for the french people, but across the international community. And of course weve also had reactions pouring in from across the globe, even irans foreign minister making a reference to the statements, a very known book about notre dame. Every single one of us who live in the city that walk past this incredible cathedral, for us its meant something i would say. The direct center of paris. Its the center of life. Usually on the plaza out in front of it there are all sorts of street performers and obviously people selling little knickknacks. People come here for the services on holy thursday, good friday, and on easter sunday. I asked the deputy mayor about the possibility of ringing those bells on friday and she said that that would likely not happen. Of course, the concern being any sort of vibration like that could further destabilize the structure. We should also note that a number of buildings to the right of that tower have been evacuated because as chris mention mentioned, theyre going stone by stone now to make sure that theres not falling debris. Because while a great deal of the wood there at notre dame, that wood has been destroyed, the stones by and large remain intact. I know there was concern that the water that was being used may have caused some damage. What more do we know about that . We spoke to several officials at the Fire Fighting service yesterday, we know that 500 forces were deployed to notre dame to try to bring the fire under control. Using water from the river by us here and theyre using drones to assess the damage. The service was angry for having been criticized by the u. S. President donald trump. Why is it were not seeing Fire Fighting planes in use. They said we have to be cautious about this. We want to make sure that we manage to hold onto some of the structure that is Still Standing. In fact, it took them apparently over one hour to be able to get inside and very carefully remove the artifacts that chris and i were just talking about. So great deal of effort from the firefighting services. I heard from one of the passer bys that was standing transfixed yesterday shouting and screaming saying why isnt more being done . Why isnt the army on site . Thank you, chris, do stick around. I want to bring in a former curator at the French National archives currently a curator and professor at cornell. Professor, thank you so much for your time. First of all, what can you tell us about the nature what can you tell us about the nature of the art and the artifacts that were being housed here at notre dame . Well, yes. Well, obviously its a huge tragedy in terms of the building. But possibly also in terms of all the art treasures that were kept inside the building. We dont know exactly whats been destroyed. We know that the crown of thorns, the most precious relic is intact. We know that wooden frame of the cathedral has been completely destroyed. The fear now is that it may take decades to rebuild the cathedral. And that it may be done with a concrete frame instead of a wooden frame. And so were just devastated. What about the artwork, the artwork that adorned the walls here . The artwork. You had a lot of art made in the middle ages during the classical period. The choir stalls were added in the 18th century. Important paintings that apparently could be removed in time. Its both an amazing cathedral and museum that burned. So the i dont know more than what was published in the newspapers so far. And the experts are being cautious. Professor, in addition to it being an amazing art gallery and housing some priceless works, religious works, artifacts, it is also a tomb. There are a number of folk whose are buried here at notre dame as well. Who is buried here . Who is where . Here at notre dame, who is entombed here . So its a place that was hugely popular and the spiritual beating heart of france, so its obviously a great emotion. But im not sure i could hear your question very well. Professor, thank you so much. Again, at cornell university. I also, again, you know, chris and i were talking about this, shes been here a number of times. The first time i was here was back in 2001 as a college student. You come to europe to backpack through this part of the world. When we came here to paris, our first order of business, notre dame. This is the picture i posted on my Instagram Account yesterday. This was roughly 20 years ago. Like so many others came to experience the majesty and wonder of this structure. Again, what hasnt been lost on folk folks who assembled here. This is a city thats committed to rebuilding notre dame. It would seem as if theyre committed to doing it as quickly as possible. 400 million already raised for the rebuilding effort. Were going to be coming back to notre dame a little bit later this hour hearing from an american living in paris. But for now, let me toss it to my friend and colleague there in new york city, standing by with the rest of the headlines. You know, just some incredible images coming out of paris right now. Notre dame means so much to so many both parisians, to france in general and also the entire world. Its kind of been a moment of unity. I think you could probably agree with me. While so much is happening overseas in paris specifically, so much is continuing to happen here at home and were going to be covering that. Coming up, we have now reporting from nbc news on the muller report. Why former white house staff are nervous about President Trump seeing their names in the report scheduled for release thursday morning. Live reports from the campaign trail. How two big named candidates struggling in the early going are trying to make their pitch to voters. Thats coming up their pitch to voters. Thats coming up wake up theres a lot that needs to get done today. Small things. Big things. Too hard to do alone things. Day after day, you need to get it all done. And here to listen and help you through it all is bank of america. With the expertise and knowhow you need to reach that blissful state of doneness. So lets get after it. Everything is all right what would you like the power to do . ® all right welcome back. All of washington is waiting for bob mullers report to be released on thursday and a new nbc exclusive report found the white house may be looking more closely. Theyre worried the report will expose them about the sort of damaging information about the president. Carol lee broke this story for us, also joining the conversation former u. S. Attorney greg brower. Carol, what do you know . Well, what we know is that as the report is closer and closer to coming out, that some former and Current White House officials who were told to cooperate with the Mueller Investigation by the president s legal team at the time are now worried about what is going to come out in the report in terms of is it going to be are they going to be explicitly named as sources of information about the president and if not, is the report going to be written in a way that makes it obvious that they were the source of the information. Meaning, like, if there was an incident involving the president that clearly one person was a party to. Then is that what is that going to do to the president . Is that going to make him and attack them on twitter . Are his allies going to start attacking them. Theres a lot of anxiety. One person described it to us as breakdown level anxiety. Do these people not anticipate this would be released publicly, the Mueller Report . I think it wasnt at the time when they were told to cooperate and talk with investigators. That they it didnt dawn on them that this is a possibility and this is how it would come out. I dont think no, i dont think some of them realized that this was what they said could wind up in a report in a way that shows the president , what they did. Some of them feel like they were in a box. Cooperate with this investigation, they had no other choice but to be completely honest. Otherwise theyd risk perjury. So now they feel like theyre going to get face the consequences. Face the consequences of that. Talk to us about the specifics here. Walk us through the precautions, if any, that prosecutors may take to protect witnesses like this, their identities, what will be redacted, wont be redacted, will names be used, that sort of thing. I think that its clear that the real issues with respect to potential redactions revolve around classifies information and what is considered to be grand jury information. Those are two difficult types of information that have to that are governed by laws and thats where most of the redaction concerns lie. This other information that might be embarrassing to certain witnesses really, in my view, is not likely to be redacted. And it brings up, as carol pointed to,i the dilemma many witnesses face. On one hand a witness has to tell the truth to investigators and to not do so can be a crime. On the other hand, oftentimes telling the truth means revealing information that might be embarrassing about ones employer or other people. So i think i hope that for the sake of these witnesses they absolutely told the truth. But, of course, when that all is revealed, it might be embarrassing for other people. In other investigations, there has been mention of individual one. Through process of elimination we surmised that was the president. You think we could see real names involved . We could. We could. In fact, i would submit for the sake of transparency in a unique important investigation like this, there likely will be transparency with only the most peripheral sort of low level employees having their identities potentially protected. But in other words, if its important to understand the import of the findings of the investigation, to reveal the identity of those who are testifying to this or that, then its simply makes no sense to keep their identities secret. Or the findings of the investigation simply wont make sense. Lets talk about the release on thursday. Were getting reports its going to be released thursday morning. We anticipated it was going to be today or thursday. Any idea what the process is going to look like . Is the white house going to have a look at the report before the public does or will this be a simultaneous document drop . Theyre going to see what it says and then figure out what their game plan is for responding. They have a number of options. We havent seen their what do they call it . Their counter report do they even have one is the question. And do they feel like i think the main question is when they see what becomes public, is it to the extent they feel like they need to, you know, go dramatic in terms of how they push back and respond, or is it something a little less than they thought . I think with just the barr summary, you know, they calibrated on that because it was seen as so favorable to the president at that time. I dont think that was necessarily the outcome they were expecting, but they definitely calibrated their response once that was clear that was the outcome. We all know the countdown is on. Two more days to go. Thank you both. I want to turn back to chris j jansing who is standing by in paris. Reporter Officials Say firefighters arrived just 15 to 20 minutes later than they did, the entire cathedral you see behind me would be gone, would be lost.
