Good day. Im Chris Jansing at msnbc World Headquarters in new york where it is now 4 01 p. M. We begin with Hillary Clinton back home in chappaqua, new york, after falling ill during the 9 11 ceremony in new york city. She did leave that ceremony early, around 9 30 this morning, after feeling overheated in the words of her campaign. New video this afternoon shows clinton clearly unstable as she was being helped into her vehicle. She was then driven to her daughters nearby apartment. And a few hours later she left chelseas on her own accord smiling and waving. How are you feeling, secretary clinton . Okay. Are you feeling better . Yes, thank you, very much. Thanks, everybody. Nbcs Morgan Bradford is near clintons home in chappaqua, new york. Whats the latest there . Reporter chris, we were here the moment Hillary Clinton arrived at her home. She was in that typical van she travels and followed by two unmarked cars as well as local Law Enforcement vehicles that were ushering her into that culdesac where she shares a home with former president bill clinton. And theyve lived here since 2000, since they left the white house. And that is where bill clinton was waiting when his wife appeared unsteady at a 9 11 memorial earlier this morning. You can see in video a sense where shes clearly leaning against her secret Service Aides as theyre helping her get into that same traveling vehicle. Now, whats curious, chris, is that reporters were not allowed to follow her or know her whereabouts for the 90 minutes following the time when that video emerged. So its unclear where she went immediately after, but we do know as you mentioned she later emerged from her daughter Chelsea Clintons manhattan home and her spokesperson said she was feeling overheated, went to her daughters home playing with grand kids and thats what happened before she came here. The question is what happens next. Shes scheduled to be in San Francisco tomorrow morning. And then she has a fundraiser tomorrow evening in San Francisco. And tuesday she has not one but two fundraisers in los angeles. In the meantime shell be here at her home in chappaqua, chris. Nbcs morgan radford, thank you for that update. Let me bring in hallie jackson. Donald trump was also at that ceremony. Any reaction from him or his campaign . Nothing. Nothing from his campaign or trump himself though nbc news did catch up with him when he was visiting a fire house in manhattan, one of the hardest hit Fire Companies affected by september 11th. Trump was there with former new york city mayor Rudy Giuliani. Lets play a little bit. He doesnt address it, says he doesnt know about it, but watch for yourself when our inbed ali vitale asked. A question about Hillary Clintons Health Incident this morning . I dont know anything about it. Not much from donald trump there. Nothing from him on twitter. In fact, today has largely been devoted for the gop nominee to focusing on september 11th. Nothing from him either about the other big political headline of the weekend which has been that basket of deplorables comment from Hillary Clinton. Instead trump releasing a lengthy statement about the 9 11 anniversary saying it is a day of remembrance and sadness, but also of resolve. Chris. A very different donald trump that a lot of people wondered if that person existed. Somebody who let the 9 11 anniversary stand on its own, only release that statement. Didnt take an opportunity today not to say that he wont take an opportunity tomorrow. And thats going to be the question, right . How does he respond when and if he ultimately does tomorrow or later in the week, you would say. Traditionally you expect a candidate, a nominee, to say theyre thankful that their rival nominee is okay and then get back to sort of the race of it and the campaigning of it. But well see how trump and the tone that trump chooses to take when and if he does Say Something about Hillary Clintons health. His first rally after all this by the way, chris, tomorrow in asheville, north carolina. It also begs the question the health of both of them becomes a bigger issue in this campaign. And it already has been in the sense of medical records and really knowing in detail about what part medical backgrounds are, hallie. And ultimately of disclosure of how much each candidate is telling us. To be clear, we know more about Hillary Clintons health than donald trump. She has put out a four or fivepage letter from her physician. Donald trump has put out four paragraphs from his physician about this. Not mentioning, for example, his medications, his family history, et cetera. So trump has disclosed less about his health. But still, for both of these candidates its less information than we have known about nominees in past cycles. It is indeed. Hallie jackson, thank you very much. Joining me now is associate professor at the nyu school of medicine or as weve always known you just dr. Debbie. Thank you. They basically said she was overheated. What you see, and thats really all we know is what theyve said and what we see on that tape, is it consistent . It is consistent. I mean, there are other possibilities. From that video i cant tell if shes near fainting or anything like that. It looks like she could have even just lost her balance with her knee buckling or something. Its not clear from that. I mean, if someone is near fainting or perhaps unsteady from that, the things you worry about is theyre not getting enough blood flow to their brain, not enough oxygen to the brain. So that could be from simple things, ordinary things like its hot, its humid. Standing. Youre getting dehydrated. In place for an hour and a half. Exactly. With a lot of people approaching you. Exactly. Sometimes when people feel a lot of pressure, anxiety, they breathe more quickly, hyperventilate and that can cause the same symptoms. And same things most of us go through, maybe we forgot to have breakfast, havent had enough sleep, all of these factors can come into play. On the other hand, you always worry or think about the worst case scenario, just as a physician those are the things you want to watch out for, right . She doesnt travel with a doctor, but theres a lot of training that goes into being a secret Service Agent. Sure. They obviously made a decision Hillary Clinton the campaign secret service didnt go to the doctors, didnt go to the hospital, went to her daughters and came out and here we see her a couple of hours later looking fine, looking like Hillary Clinton waving, talking to that little girl. Is that another indicator that it may well have been what they said it was . I think so. I mean, she looks pretty healthy, she looks comfortable. She looks like her usual self saying hello to the little girl. I personally as a physician would have recommended just getting checked out of course, you know, if there is any possibility you might be fainting you worry about just cardiac causes. Which can happen to anybody. For someone whos on tours, you might be thinking about could they possibly have bleeding and low blood count. Im not saying those things are happening, but things you think about. So you look at a persons medical history maybe she gets checked out. In a case like this where any of us on a day like today or yesterday to me felt worse in new york city, you could be overheated, get into a cool place, rest and hydrate. Exactly. Have something to eat and feel much better. Dr. Debbie, thank you so much. Nice to see you. Time for a quick break, when we come back, america remembers, today marking 15 years since the attacks that changed this country forever.

[ bell ringing ] todays ceremony marks 15 years since the terrorist attacks of 9 11. Lower manhattan of course was ground zero. Friends and Family Gathering there today to remember more than 3,000 people who died. For more on our coverage of todays anniversary, joining me now nbcs rehema ellis. After 15 years remains an emotional day for i think almost everyone in this country. What can you tell us though particularly about the families who came back this year . Reporter chris, i can tell you that if you watch the ceremony today, you saw people crying. You saw them wiping away tears. You also saw some at moments where they smiled, closed their eyes and remembered. One man who lost his son here, he said that his heart is still broken, but one of the things that he feels about his sons memory is that its important for him to go on. So hes devoted his life to reminding people to what this area is all about, and that it is sacred ground and its important for people to never forget. There was another young man that we heard from today who talked about he was only a child. And hes come of age now, hes a man himself, who lost his father 15 years ago because he worked in the north tower. That young man now spends his life helping people who are devastated by tragedies. Both of these families say that they think that the best way they can honor the person whom they love is to keep getting on with their lives. I heard it again and again, not just today at todays ceremony, but ive heard it every year over the past 14 years 15 years since people died here on 9 11, chris. Nbcs rehema ellis, thank you so much for being there for us today. President obama also paid tribute to 9 11 victims at the pentagon today, laying a wreath to honor the fallen. And urging americans to find strength in our diversity. Groups like al qaeda, like isil, know that we will never be able they will never be able to defeat a nation as great and as strong as america, so instead they try to terrorize in the hopes that they can stoke enough fear that we turn on each other and that we change who we are or how we live. And thats why it is so important today that we reaffirm our character as a nation. And in shanksville, pennsylvania, bells rang in honor of the passengers on flight 93. They fought the hijackers preventing them from attacking what may have been the target, the capitol or the white house. Joining me now is nor man manetta, secretary of transportation on 9 11. Secretary, good afternoon and thank you so much for being with us. And everyone has a memory of where they were that day, what they heard, what they saw. You were a member of the cabinet and were summoned to the white house bunker. Tell us about your experience. Thanks, chris. I was with the deputy Prime Minister of belgium who was also the transport minister isabel durant. And with jay garvey having breakfast in my Conference Room, and my chief of staff came in and said, may i see you. So i excused myself. Went from the Conference Room into my office. And at the other end of the office was a tv console easily recognizable World Trade Center with black smoke coming out of it. And i said whats that . Whats going on . He said, we dont know. We heard the possibility of general aviation aircraft, possibility of a commercial airliner, possibility of an internal explosion within the building. So my chief of staff and i watched the tv and i said ive got to get back into that Conference Room. Keep me posted. So i went back in and explained what id just seen on television. And several minutes later john came back in and said, may i see you. So when i went back into my office, he said its been confirmed its a commercial airliner. So i went up to the tv console and im watching the program, doing some channel surfing, and then all the sudden this gray thing goes across the screen, disappears and then from the left hand side from the screen this white, yellow, orange, black, billowy cloud. And i said holy cow, what the heck was that . Or words to that effect. And so i went back into the Conference Room and i said i dont know whats going on in new york city, but i know im going to have to deal with it. And, jane garvey youve got to get back to the Operation Center of faa, and mrs. Durant, youll have to excuse me. By the time i got back into my office, someone from the white house had called and said get over here immediately. So i put some manuals and stuff together and put them in my briefcase, went downstairs into my car and we drove over to the white house. How soon was it, secretary mineta, before it was clear to everybody and was it by the time you got to the white house that america was under attack . No, not at that point. Because i got out of the car, went into the situation room and got briefed by dick clark. And what he briefed me on is not much more than i had already heard on television, but then he said youve got to be in the peoc, he said thats the president ial emergency Operation Center, a bunker way under the white house. I said i have no idea where it is. And the secret Service Agent said ill take you down. So i went with them to the bunker. And stayed there the rest of the day. So just the fact that you were taken there was clearly an indication of the seriousness of what was going on. At some point an unprecedented decision was made ordering a ground to all the planes in the u. S. Tell us about how quickly and why that decision was ultimately made . Well, in the peoc, president ial emergency Operation Center, theres a big table, a long table probably 30 feet long, maybe 15 feet wide. And i was right across from the vice president. The military assistant came in and said theres a plane heading towards d. C. So i said to monty belcher, number two at the faa on the phone, monty, what do you have on the radar on the plane coming to d. C. . He said, well, weve got a plane coming from d. C. , but the transponders been turned off so we dont know anything about the aircraft except that we catch the target on the sweep of the radar as it goes around. And then when i said where would that airplane be . And its hard to see a radar related to a point on the ground, so he said, well, probably somewhere in the middle of pennsylvania. So every so often id ask him, wheres the plane . Well, probably north of baltimore. And wheres the plane now . Well, probably near rosland. Wheres the plane now . Near Pentagon City going towards national airport. Wheres the plane now . Mr. Secretary, oops, weve lost the target. Whered you lose the target . Somewhere between Pentagon City and the national airport. And then about that time someone broke into the line and said, mr. Secretary, we just got a call from Arlington County officer, police officer, saying he saw an American Airlines plane go into the pentagon sochlt th. So then i said to monty, monty, thats the third commercial airliner today within the last three hours thats been used as a missile. And when you have one of something occur, its an accident. When you have two things of the same thing occur within a relatively short period of time, its a trend. But when you have three of the same thing happen within a short period of time, then you got to consider a plan or an action. So i said, monty, in the military they have something called a standdown. And were going to have to do our own standdown. So lets bring all the planes down. It was an extraordinary moment that day. I remember it. And then of course there was the fourth plane, flight 93. And as we just mentioned the people onboard were able to wrestle the hijackers and save countless lives. Absolutely. Do you believe that was aimed at where you were at the white house . Well, you know, al qaeda used to always talk about the military icon, political icon, the economic icon. And today they had hit the economic icon at the World Trade Center, the pentagon, the military icon. So i will always be eternally grateful to those people on that airplane for having taken it back from the terrorists who had taken over the plane. They got the plane back. And well never know, but that plane could have been heading towards the white house or to the capitol. So that plane that captain took that plane straight into the ground in the fields of shanksville, pennsylvania. So many stories of heroism and so many lives lost that we remember that day. Former transportation secretary norman mineta, thank you for spending the time with us and sharing your remembrances. Its good to see you, sir. Thank you, chris. Its an honor to be with you. Co
