Good day, im Andrea Mitchell in washington. In france today, 10,000 troops spread out across the country. A security blanket for a nation that stood united against terror threats during sundays solidarity march a historic gathering of 40 World Leaders, notably lacking in any high level representation from the United States. The investigation hit somewhat of a roadblock. Officials say Hayat Boumediene is in syria. Ron, what is the latest from the investigation . Reporter well, that development that you just cited, andrea that boumediene is in syria and that she left the country apparently before all of this began back on january 2nd. A couple of things that means. A, there was perhaps an even greater level of planning about all of this than has been revealed and officials here investigators here are trying to get to the bottom of all of that. It also means there were obviously other people involved in this whole episode. Another thing they are trying to get to the bottom of this. We know the gunmen claimed links to al qaeda and isis and that is a big worry here. Whether there is an active cell here that includes other people with capability and what that capability might be and whether they intend to use it. Now, in the coming days not down the road but theres still this concern about a possible imminent threat which is why security has been so beefed up here. And a significant part of that security is going to the Jewish Community here to protect schools and synagogues. After what happened at the Grocery Store where four jews were killed targeted because of who they are and antisemitic acts and because so many people fled that community for israel because of the fear of living here in france those are the reasons that theres so much security being added there now. All of that underscores what has happened here is an ongoing problem all the worlds attention was focused on france and paris specifically because of the attacks of the past few days. Theres a huge problem that im sure i know youre well aware of, that the world is now focused on of terrorism and the home grown kind. Ron, one of the issues now is the publication of Charlie Hebdo the substitute editor they are going to publish a new edition. She spoke with ronan farrow. No matter what well continue. You can kill our colleague or friends. You wont kill the spirit of liberty or the spirit of blass femmy. A lot of courage on the part of that publication. Reporter a lot of courage. A lot of admiration and respect and still grieving. Over here behind me in the center of the plaza, theres still crowds gathering to pay respects. And you see the words up there perhaps, charlie je suis charlie. When you talk to people about this whole thing, its about liberty and freedom. Theres a very high mindedness about what has happened here. When you think about it the magazine Charlie Hebdo was a small circulation magazine 30,000, not that big. Its more of a novelty item if you will and unique because of the nature of the satire it contained. That attack on that entity has brought out what it has brought out and millions that came out yesterday. That is because people see this as weve said more of an attack on the values and the underpinnings of this country, not just a group of journalists if you will. And the idea of freedom of expression not just the idea of freedom idea of freedom of speech. Not just the idea of the ability to write in a journal. Which has been impressive here. Why i think so many World Leaders came here yesterday and why i think so many millions of people poured into the streets perhaps as many as 3. 7 million is the estimate ive heard, not just in paris but other cities across france. And just standing here in all of that yesterday, i have to tell you, i was trying to think what you compare that to. It was just a very unique experience. There were several hours during which we could not move from this position. I couldnt move this far without it taking very long time because people were so packed in. It was calm and it was nonviolent. There wasnt a single incident that i heard reported of violence or confrontation. And that was remarkable. And just to see those scenes and to be part of those scenes. The french say it was historic it was historic why they really wanted to see a high level visit by president obama and Vice President biden and secretary kerry, someone from the United States and eric holder being here people dont understand why he didnt take part in the march, even symbolically. Ron allen, i know you spent many years overseas as a Foreign Correspondent for nbc news youve had a lot of experience in that part of the world. Your reactions are so significant to me. Ambassador, thank you so much for being with us. Our condolences to you on behalf of all of us here and me personally, i cant even imagine what you and the people of france are going through right now. Thank you very much. You know actually we have been overwhelmed by the expression of solid solidarity and grief and all corners of the american people, from the highest level of the Administration Since president obama came to the French Embassy and secretary kerry, to the ordinary americans. I can say americans are compassionate people. You can understand there is controversy here the newspaper filled with it. We as well have been talking about it because eric holder the attorney general was in paris, he was doing Network Interviews and the president was in the white house and Vice President was ats home in delaware. Secretary kerry was in asia and india and on his way to pakistan. He was previously engaged. But there is a question as to why no cabinet level or higher presence when you had 44 World Leaders, including the Prime Minister of israel and others who are also under security protection. To be very frank, the First Impression we had is the support, expressed by president obama. Secretary kerry made a speech the speech in france and come back to paris before the end of the week. So from the french side there is absolutely no feeling no hard feelings. The tradition of free speech it all began in france during the 1700s and 18th century. But there are laws in france laws that say you cannot deny the holocaust, laws that say you cannot deny the army why is it this is a debate were having in the United States as well you know. There is no law of denial of genocide only one law of denial of the holocaust. Its not an opinion. It took place. You dont express an opinion when the holocaust took place, its a fact against the victims and Jewish Community. For us its not an opinion. But apart of the holocaust, everything is allowed. Of course if there is no libel, you know against one person an individual. What about the investigation now . Was there a failure of intelligence these people were known to the french and known on a nofly list to america. Should they have been followed after one of them got out of jail after the yemen trip . One correction i think this guy was not on a nofly list of americans but he couldnt get a visa to go couldnt get the from the american administration. But there was no fly zone no fly he was not on this list. The problem we are facing you have a few thousand young people radicalized. And they went to syria or coming back from syria. And if you the fact you are radical, its not enough to get arrested. You cant arrest somebody on its opinions. We have to monitor them. But a few thousand people to monitor one person you need ten agents. Its simply that you cant monitor all of these people 24 7. So of course there will be an investigation to say what went wrong, certainly something went wrong at some moment. But at the same time the fight we are facing is really very very specifics. What about boumeddiene and what threat she could still pose . Apparently she was but again were in first hours of the investigation. She was married to coulibaly, the murderer of the jewish grocery shop. We didnt know she was in contact right away. She was in contact with one of the girlfriends or wives of the two other terrorists and exchanged hundreds of phone calls in the last year. So she was part of that. She left shes apparently in syria. So we have to see, really what was her role. The question was whether she had an active role or whether she was supporting her husband . One of the questions is that the men may have understood they were under watch and women may have been been communicating to do the operational planning. Are there any other accomplices at large . We dont know. Really its for some time the french authorities have been theorying such a terrorist attack. The minister of interior who is now the Prime Minister told me personally sooner or later there will be something because we simply cant prevent hundreds of people from doing it. It happened. In a sense it was worse than what we were expecting because these people were acting in a professional way as a military command o, obviously we are not over with this fight. One other political question you have the forces right wing do you fear an antimuslim backlash . Do you fear that france could go too far . There are suggestions that this country went too far after 9 11 in some of the security procedures. Theres been a lot of criticism. How do you achieve a balance and not lose what is sacred in france . You know we are facing the same challenges as our american friends. There were a lot of incidents against muslims in france today. So of course its its a blessing for in a sense, really, its a good argument for the extreme right, which everywhere in Europe Germany and u. K. And france was very antimuslims. So at the same time, you saw what happened in paris. It was moving. I was moved to tears. It was really a will of the french people to affirm the National Unity and message of the president of the french republic. Lets hope we keep the spirit of National Unity. Mr. Ambassador, thanks so much. Thank you very much. It was an icy, slippery and dangerous commute for millions of americans this morning. Mike seidel is in savage maryland with more. Reporter good afternoon, from interstate 95 were midway between d. C. And baltimore. Looking at northbound traffic on a wet interstate. 695, thats the beltway, 11 miles, 11 minutes, traffic is moving at a pretty good clip. The roads are wet but not icy. Temperatures have been hovering around 34. There have been issues during the Morning Hours across parts of maryland virginia and West Virginia primarily north and west of the baltimore d. C. Area. Icing reports on some of the neighborhood streets and overpasses at an dulles and frederick and towards the pennsylvania line. As temperatures there dropped right down to freezing and some of the moisture froze up on cold surfaces because it was so cold last week. Now temperatures in most areas have risen above freezing. Those advisories will fall off the boards and through the afternoon well see temperatures in d. C. And baltimore warm up to the mid to upper 30s. Rain will end this evening then it will be cold and blustery again tomorrow much like last week with highs only around freezing. As far as schools, most had a twohour delay. A couple did throw in the towel eventually. At the airports some cancellations, about three dozen Flights Canceled out of reagan nearly 20 at dulles. Delays have been minimal too. Two dozen flights delayed at Reagan National 5 of their monday schedule. Overall, not a major impact from this situation here in washington and baltimore. Back to you. Thank you so much mike seidel from the weather channel. Back in a moment with adam schiff. Fort. Absorbs 2x more than you may need.

Were in seattle to see which 100 calorie black cherry greek yogurt tastes best. Definitely that one. That ones delicious. Its yoplait what . I love yoplait the other one is chobani. Really. I like this one better. Yoplait wins again take the tasteoff for yourself. The nissan rogue, with safety shield technologies. The only thing left to fear is your imagination. Why did the terrorists who attacked paris escape the net of french intelligence . They had been on u. S. And french watch lists but not being tracked adequately apparently. Joining me now is adam schiff thank you very much for being with us. Thanks, andrea. There is a question as the ambassador said, how can you put everyone under watch . They have such a large percent of not just muslims but have been back and forth to syria, many more than we have in the United States. Thats exactly right. I can certainly empathize with the challenge they face its not as if they went on vacation they went to surveil other people that may have been a greater threat or viewed as a greater threat. This is a challenge we face but because theres so many foreign miters that have lift france to join the fight and jurpeuropeans who can come to france easily. They are inundated with the request for surveillance. Do you think there are any American Security changes warranted . Or do you think this will slow down the president s efforts to release people who have been vetted from guantanamo . What are the implications for the United States . Well you can already see people making the argument as indeed the case after every tragedy to support a policy position that theyve advocated before the tragedy. So it will have an impact potentially on guantanamo and impact potentially on the Metadata Program and fisa court. I saw the director of the nsa making the argument, we cant reform the Metadata Program now. Thats not true. Yes, we need the capability, but doesnt mean the government has to hold on to all of that data. We have to be careful not to use things that dont lead us to the same conclusion that some of the advocates are pushing. But it will affect the debate. In terms of our own security processes here at home i think it will accelerate some of the imperative that we better coordinate at the Community Level that we work even more closely with americanMuslim Community, part of the solution. That we make sure that we are having good information sharing with our foreign partners which is ongoing, but well have to intensify. Here in the United States the Muslim Community is far better assimilated as much as it in france and other parts of europe. I want to ask about this failure of any cabinet level or higher official to show up at the march. 44 leaders. Theres been a lot of criticism. I cant explain why it wasnt possible for the president or Vice President. We did have high level people in france, the attorney general, the deputy secretary of Homeland Security were there for a security conference. The president made a personal condolence call. I think as a practical matter the french know and understand our close solid dart with them in the close time of need and apart from the symbolism, which is important, the most important thing, do we have a level of cooperation with the french. Theres no question about that on either side of the atlantic. We have intense cooperation. One of our closest allies and thats only going to continue and intensify. Congressman adam schiff. Thanks for being with us. Big developments in the search for airasia 8501. They have found the data recorder but not the cockpit voice recorder. Reporter andrea that flight data recorder has been brought back to investigators in ja carta. Air speed, altitude what the engines were doing. It will take them time to go through it possibly two weeks, maybe more. Maybe more like four weeks. As for that cockpit voice recorder, they believe they know where it is on bottom of the sea. The problem is its under very heavy wreckage. What they may have to do is lift the wreckage out of the way using flow tags devices like they used to lift the tail section of the plane over the weekend. Theyll take another look at first light at about six hours time. Thank you so much. And up next from paris to syria, tracking the woman wanted in connection with the Charlie Hebdo massacre.
