today. >> depending on the time of the day, or the weather around that part of manhattan could be quite blustery or can actually be dead still depending on the time of the day and the weather systems around. you're saying then there will be no adjustment of her schedule. some doctors have said maybe there should be an adjustment. any discussion had that you heard of coming from the campaign? >> so far the campaign is saying she will go on as scheduled. i want to read you something here, her spokeswoman said this is coming from jennifer palmieri, hillary clinton released a detailed medical record showing her to be in excellent health. she's saying this in rebuttal to things they were hearing from trump's campaign and people supporting trump saying that, you know, they haven't heard a lot of things about hillary's health. she was rebutting that saying, look, she's been in good health, she's been clear and forth coming about her medical records, again, today's medical record and today's evaluation is something a little bit more

detailed than we have seen in recent days. and, again, it is -- there is more questions that are arising for the press corps. people are saying, where were you in those 90 minutes and why did you say it was related to allergies only to say it was related to pneumonia and then if that happened friday, why are we hearing about it on sunday after we saw visible evidence of you appearing unsteady? these are questions that we're still trying to get answers for. she is scheduled to appear on schedule and remain in her time and place tomorrow in san francisco and then subsequently for two fund-raising events on tuesday, traveling down to los angeles. >> as you were reporting just now, we heard from a senior aide that the california trip is very much in question at the moment. the campaign discussing whether to travel or not tomorrow. perhaps just out of absolute caution, right, or a follow-up appointment, we don't know any details right now. put in context if you will, you gave us a sense of the schedule, at least as it stood, right, for

the next couple of days, what their schedule had been leading up to today, they hitting, if you will, high heat post labor day. >> this is absolutely -- you put it best, this is high gear. this is the time she has to swing and speak to those voters, especially those voters perhaps still on the fence. we only have a number of weeks until that election. so this is a critical time, not only for secretary clinton, but also for her opponents and she's aware of that. she's aware that now is the time that she has to pound the pavement, she has to convince those voters and has to make her case. so this has been a pretty tough schedule by anyone's standards. she has to be in a lot of places and, again, to give you a sense of the schedule facing her, that's a lot. this is going now resting home, after being in new york city, and manhattan this morning, coming to chappaqua this evening, hopping on a plane, going to northern california tomorrow morning, only to be in southern california just hours later for not one but two events. that gives you a sense of what a

lot of the politicians are facing. more importantly, when it comes to this very peculiar and crucial period leading up to this election. >> you were at chappaqua at her residence for some time, did you notice any activity out of the ordinary, if you will, here? >> it was actually really subdued. two orange blockades that are meant to keep people away. i started to go through them because i was trying to meet our camera crew. but it is very quiet. one man there signalling to me i was not allowed to go through there. but we were standing there when she arrived with her motorcade and a pretty small motorcade relative to other events we have seen her in. she had one -- her van in the beginning and two unmarked cars following behind her. and there have been local police traveling through the neighborhood, explained to people where they can park, where they can't park. there are some curious neighbors coming by and just even as i've been standing here, people asking me what is going on? we understand the clintons live

here. the commune ity is concerned. >> before we let you go here, so you can get back out there, that's one question, about the doctor itself, as we reported over the last 15 minutes, she did have a -- if you will, a visit by her doctor at her residence as you are reporting. with had her -- when she's on the road, she clearly has secret service personnel. they also have some emt training, do they not, in case there is assistance required? >> that's what we're understanding but there is not a doctor there with her at all times. this is on an as needed basis. and today it appears that it was as on an as needed basis. and precautionary one. anyone's health in question, they want to make sure she's in tip-top shape, especially as we just mentioned she had this duelling schedule where she has to zigzag across the country.

this is something where the people around her have the skills necessary to reach help if they can't provide it immediately. >> morgan there in chappaqua, new york, thank you so much. villing developing news, a statement coming from her doctor, saying that secretary clinton was diagnosed with pneumonia, that is what is new at this hour. 6:05 p.m. eastern time frame. we're also hearing at this hour that there could be an adjustment in her travel schedule coming tomorrow. original schedule was to get to california. that's under serious reconsideration. we're hearing per a senior aide. the pneumonia, we're hearing that from the doctor and the development of the change in travel schedule. i want to bring in now dr. debbie parumpel from nyu school of medicine. what did we learn in the last hour? is this diagnosis of pneumonia,

many things to consider here, we learned about it today. yet the doctor saw her on friday. the immediate question is how can one function if they're diagnosed with pneumonia and how severe might it be? >> by itself, it doesn't need to be dangerous, but has to be taken seriously. it is possible that she saw the doctor on friday, they started the antibiotics to treat it and she might be getting better but they could only make the formal diagnosis on sunday. sometimes the labs tie s take a to come back. on the other hand, since pneumonia is easily treatable, for the most part, people have to take it easy, keep hydrated and stuff, it might not impact her travel schedule as much as we would worry about. >> we're looking at the detail coming from the comment and statement from dr. lisa bardak and saying that -- i'll read again from it, secretary clinton has been experiencing a cough related to allergies. and friday during a follow-up

evaluation, her prolonged cough was diagnosed with -- excuse me, she was diagnosed with pneumonia. so could have that cough been more than allergy potentially early on? how do you put together what we were seeing there in that statement? >> i agree. i think it is more common for people to have a cough from pneumonia first and whether it is bacteria or virus, sometimes that can trigger an allergic reaction. you might see somebody coughing for a prolonged period of time because of allergies afterwards, but the two can go together. it actually fits pretty well. i mean if someone has pneumonia, there are a couple of different things that can make them light headed. you burn more fluids if you're sick. it is easy to become dehydrated from that alone, especially if you have a fever. if you have pneumonia, you might have lower oxygen levels and slight difference in that amount of oxygen can make you feel more light headed or like you might pass out. and finally if you're on antibiotics, a lot of people might feel nauseated when on

antibiotics, may not have a good appetite because you're sick or on the antibiotics. if it causes gi symptoms, upset stomach or diarrhea, all the factors can make you more likely to be dehydrated. >> she was put on antibiotics. that's what dr. lisa bardak said. what are we talking about? would they have to be extremely strong or a whole sort of different types that you would prescribe here? >> a whole assortment. usually if someone comes in and you see things on their lab tests, the ones that come back sooner, your white blood cell count, a measure of you fighting infection, if that is raised, we assume it is a community acquired pneumonia. general pneumonia. and you get started on oral antibiotics, not necessarily anything super powered but things most effective. she probably was started on that if that's the case. but sometimes you'll get tests back later where they find out which bacteria it was, perhaps from the sputum, so you might

tailor your regiment based on that. >> we see secretary clinton and she was out this morning and very warm environment, would it have been suggested that she stay away from that given that the symptoms involved from pneumonia, when you go to the textbooks, say you got a fever or a cough and as you were discussing all these other symptoms, should she have been down at 9/11? excuse me, ground zero? >> we tell patients to stay home, take it easy, rest, stay hydrated. but it is 9/11 and perhaps she wanted to be there to show her support and not miss that event. now, of course, you have to be careful too because if you're infectious, you might get other people infected as well. if she was on antibiotics, presumably she was okay. >> i want to ask you about walking pneumonia. to rehema ellis. down at ground zero. she was there earlier today. this is a place that you know well. you reported on these

anniversaries. this anniversary, this 15th anniversary was a warm one certainly. what were the conditions like that you experienced and felt when you were there? >> according to national weather service, the overnight temperature here was 81 degrees. that was in the middle of the night, no sunshine. by the time you get here in the morning, we're starting at 81. it was extremely humid. so for someone to be in those kind of conditions, and to be standing probably for more than an hour, hour and a half as i was standing and they were not drinking, they did not have the opportunity to get water or any other kind of libations, it can be taxing. i know i felt that the humidity was feeling very heavy on me. so those are the kind of conditions that existed here. overnight, we started with a temperature that was 81 before the sun came up. >> if you can, we're looking at the video from earlier with secretary clinton, as she was speaking with various

individuals, what part of the ground zero memorial was she at? was it in a recessed area? there is lower areas, higher areas, describe if you can, because this video is very much zoomed in. >> i can't tell you exactly because i wasn't there, and so i was seeing the image pretty much that you were seeing. but in the area where the ceremony takes place, it is where all the dignitaries stand. and it gives them a very good opportunity to mingle with some of the families and also to see the activities that are taking place on stage. so what is happening again, it is very crowded. she was wearing dark clothes as was appropriate for the day. and it was very humid. again, the conditions. high humidity, heat that began at 81 overnight. that was the overnight temperature and not having an opportunity to take in drinks or cooled water and no cooled breeze then like there is a cool

breeze now. what we have then was a very warm and humid air that was hovering over all of us at that time. >> as the pictures are showing here, behind you, we can see certainly a breeze moving and we're looking at the video earlier, there was a tree in front and the leaves not moving. so what the different times, different hours of the day will bring to that location. rehema ellis, thank you very much. donald trump was also at ground zero today as we were talking about where secretary clinton was. and they were both marking, of course, the 9/11 anniversary. hallie jackson is covering the trump campaign. on this day, it seems that the trump campaign is very much focusing on that commemoration and really not reacting to the headlines that we're discussing this hour. >> no. any of the headlines really. not only clinton's health scare but in addition trump not coming out and publicly speaking about that line she delivered to that

fund-raiser friday night about half his supporters being that, basket of deplorables. nbc news was there when donald trump visited a firehouse in manhattan, rescue one. he visited with new york city mayor rudy giuliani and one of our embeds asked him about clinton. i want to play that. see how he quote/unquote responds or doesn't respond. listen. >> a question about hillary clinton's health incident this morning, her health incident this morning. >> don't know anything about it. he decides not to talk to the press. calculation for him that on this day, as he was leaving this firehouse, after -- you saw that video being at the 9/11 ceremony at ground zero, deciding today was not about politics and avoiding the topic all together. we reached out to the campaign, which has not responded to that

end either. for trump, the question is going to be if he chooses to respond, maybe tomorrow or later in the week, how he ends up doing it. will it be online in a tweet, will it be something like an expression of gratitude that hillary clinton is okay or will it be, you know, more of an attack on her health. we're waiting to find out and see when and if he responds. >> since we're talking about health and medical records, we look at secretary clinton, she's released much more at least to date than donald trump has. >> sure, he's got four paragraphs out from his doctor that ends with his doctor saying if elected, donald trump would be the healthiest president of all time. hillary clinton has four pages out from her doctor, releasing, for example, her medications, her family medical history, more details certainly than we have seen from donald trump, even with increased calls for donald trump to go ahead and release that information. you remember that story we did with trump's physician a few weeks back where trump's physician said he felt like he was rushed writing up that letter about trump's medical

history and medical status. it is important to note, though, even while clinton has certainly leased more information than donald trump, neither candidate released as much as we have seen from other nominees in the past. >> hallie jackson following the trump campaign for us today. thanks for that summary. appreciate it. i want to bring in our panel, philip bump, political reporter for the washington post, david corn, washington bureau chief for mother jones and msnbc political analyst, we also have luciana lopez for reuters. philip, we'll start with you on this. we were hearing from hallie jackson and that's the comparison of what donald trump has released so far as well as secretary clinton. when we look at that, and the trump campaign hasn't gone there yet, right, and so for today, it is more we have these headlines, two just coming in in the last hour. friday, diagnosed with pneumonia, only hearing about it today.

and an adjustment perhaps in the travel schedule. will this hurt her because when we look at the three days that have gone, the two or three days that have begun by since this diagnosis happened? >> i sort of doubt it. this is a very difficult thing to call, simply because it is a weird situation. if we look back at 2008, when there were a lot of questions about john mccain's health, questions about his age, it was hard to separate that out from the fact that he had chosen sarah palin as his vice presidential running mate, something a lot of people were skeptical about. it is hard to know how this will play. a george washington poll that was done in september that asked people who they thought was healthier and more healthy enough to actually get the job done. essentially broke down along partisan lines, people supported hillary clinton said hillary clinton, people who supported trump said trump was. i don't see how there is a clinton supporter who now says i'm going to vote for donald trump because i'm concerned about this pneumonia. it is hard to predict, but seems unlikely. >> as we have been following

this story about secretary clinton's health, a question that has been really pushed by the republican in many knee here. and as many reporters as they have looked at these accusations coming from donald trump have widely said, you know, unfounded, you have to go back to 2012, to look at a health condition that might bring up a question. but since then, nothing. at least that's what's broadly been said so far. when this happens today, does this now make it a story, whether or not the accusation coming from the republican nominee is true or not? >> what i think this underscores is the need for both candidates, both of them to release more detailed medical records. we have some information from clinton, not a ton, but we have some. and we have that letter from the doctor which has been criticized for some of its wording and really that's it. we don't know as much as we would like to know about both of the candidates. this is a moment for both campaigns to show more transparency, step up and

release some medical records. >> david, would you suggest that happen as well, release a more thorough record of each candidate's health record? >> i think we do need it for most. i give hillary clinton credit for doing more and having her general doctor release a statement. what trump did is he had his gastroenterologist, not a regular doctor, not a fellow who could address a lot of different issues release a letter that made no sense in terms of medical practice. so he's really far behind, which means he may have to be careful if he's going to try to exploit today because the answer everybody comes to is hillary should offer more information. but if she does, he should as well, and that also brings in the question of taxes. he has a greater transparency problem, he is 70 years old, he looks a little overweight, we don't know anything really about his health. and so he's vulnerable too, but i think philip is right, it is

very hard to see how this gets used to change anyone's mind in terms of who they're going to vote for. >> should the trump campaign just stay away? this is a former secretary of state. you would not want to necessarily handle this issue, this unfortunate, if you will, situation, where we have the video of her moving into a van, in the wrong way. this can really leave a sour taste in some folk's mouth. >> a typical campaign, which the trump campaign has proven not to be, a typical campaign would release a quick statement. one thing i think if i had to play predictor now, which i gus i will, is that i feel as though some trump supporters at least will use this as a validation of their conspiracy theories that have been ongoing. all these conspiracy theories about her health, all these different diagnoses out there that are unfounded and my theory is that people will say, we were right, she is sick, which isn't

borne out by what happened today but extend that outward and all the other conspiracy theories, we were right about the health. so i think that that could be the slippery slope that we go down. it will be interesting to see how the trump campaign handles it. >> dr. oz will have donald trump on this week where he'll talk about his own health record. most likely will also discuss secretary clinton's health and health record as well. this will give him a platform to really go deep if he wants to on the headlines that have come up within the last several hours. >> yes, and i agree with philip, this is hardly been a normal or typical campaign, and trump hardly feared to tread in quite a number of places that people would have thought were anathema to the last election cyclpsychc. trump is usually quite up for talking about how much better he is than a lot of other people in a lot of ways.

i'm expecting some comparative language to put it mildly. again, i think the way for both campaigns to deal with it is to release more information, put it out there, let us know what is going on and that's how you get people to know what the real status of your candidate is. >> the key question here is those who are the swing votes, right? who are the independents here. quickly here, when they hear the headlines, the pneumonia, what happened on friday, learning two days later, what will it mean to them? >> i think two days later won't matter to people outside the media. we should have known earlier. i don't think voters care about that. donald trump has been trying -- already said she's weak, doesn't look presidential, doesn't have the strength and stamina. if there is anybody who is susceptible to that type of unfounded argument, these headlines might help trump make that argument, but i do think it

goes too far down that, he's going to be in a put up or shut up position about his own health and who knows what the story is there. we may need more than an appearance on dr. oz. >> david, luciana, philip, stand by. we're going to move to more coverage ahead. we'll have on this breaking news, hillary clinton's doctor saying she was diagnosed with pneumonia on friday. we're just learning that within the last hour or so, we'll have more on that breaking news after this. max and i just discovered

we're back with more breaking news coverage. if you're just joining us, we're learning within the last hour or so hillary clinton's doctor releasing a statement after examining her at her chappaqua home today. saying, quote, secretary clinton has been experiencing a cough related to allergies. on friday, during a follow-up evaluation of her prolonged cough, she was diagnosed with

pneumonia. she was put on antibiotics. and advised to rest and modify her schedule. while at this morning's event she became overheated and dehydrated. i have just examined her and she is now rehydrated. and recovering nicely. rejoining us now is dr. debbie. she's a physician and associate professor at nyu school of medicine. we were talking earlier, doctor, we were -- wanted to make some of the distinctions of what pneumonia might mean. we often hear walking pneumonia, and what that might be. >> walking pneumonia is more common in people under 40, more common in people in crowds, in which she may be more susceptible, but the military or in school. it is possible she has that. but usually we separate pneumonia into two categories, viral or bacterial. you get started on antibiotics presuming that it is a bacterial pneumonia. and then tailor the antibiotics depending so you can treat it. it is possible to have a viral pneumonia in which case you have to wait it out.

>> which is worse? >> it depends. they can both cause the same problems. it is about how much they affect your oxygen in your blood, your oxygenation and blood flow. both can have very serious effects. i would say in this case, the thing that makes the biggest difference in terms of the prognosis is the person's underlying health. so if you have someone who is in pretty good health, pretty high functioning, who can take care of themselves, then for the most part even if they have a pneumonia, they have a good chance of balancing back from that. on the other hand, if you have someone in poor health, in bed most of the time, not as functional, who has other issues, let's say, other medical conditions, then pneumonia could be enough to tip them over the edge. it could be fatal. >> there are vaccines related to pneumonia as well. >> the pneumo vac. it depends every year -- the general pneumonia that is out there. not that you're necessarily predisposed to something, but being out in the community, this

is a pneumonia you may be most likely to catch. >> similar it a flu vaccine? >> exactly, same idea. it is not 100% effective, but for the most part it can lower your chances and usually offered to people who are more susceptible to pneumonia. for example, smokers, people who have copd or other issues, asthma, which because of had her age she may have gotten it as well. but doesn't have those other conditions as far as we know. >> depending on who you're going to get your advice from, there are certain suggestions based on your age that you would be more susceptible to this and perhaps you should, for instance, take more precautions in this case maybe getting the vaccines. >> i agree. i think -- i think people should follow the general guidelines. i'm always in favor of getting the vaccines that are recommended. but not necessarily that people should be on stronger antibiotics or go overboard with additional vaccines that may not benefit them. it sounds like she's kept up with the regular screening and done what is appropriate. >> what we just learned within

the last 0 minu30 minutes or so they're reconsidering her travel schedule, in california tomorrow, we have doctthe docto statement we were reading and i'll repeat what was said there, that secretary clinton was advised to rest and modify her schedule. so if you are diagnosed with having pneumonia, it is not stay home, it still could be you're still able to work. >> well, for the most part, doctors will recommend you stay home. for two reasons so you can rest and recover and so that you don't spread the infection to other people. especially depending on the type of pneumonia it is. you're not forced to do that. these are recommendations, depending on the person they might choose to go to work or choose to still do what they need to do. it is possible for her to travel. she came to the 9/11 commemoration. but she may want to limit her schedule just so she has enough of a chance to recover. >> how long are you contagious with pneumonia? >> if you have a bacterial

pneumonia, treated with antibiotics, usually this will start to take effect within a day or two so you might be okay to meet with people and not necessarily spread the infection. on the other hand if you have a viral pneumonia, the antibiotics are not going to change anything. it is a matter of your body beating that viral pneumonia. and then preventing you from being contagious to others. >> when we hear pneumonia, it is a big word, by itself, pneumonia, number two, a lot of worry around it. it is not a cold. make that distinction for us. >> both come from the same general causes, where the infection is. with a cold, that's usually a virus infecting the nasalpharnyx. that can spread, whether it is viral or bacterial and out to the air ways and the lungs. when the infection is in the lungs, it is more of an issue because it can affect your oxygenation. if someone feels like fainting or they faint, it could be

because your brain is not getting enough oxygen or enough blood flow. if you have pneumonia, there are two different reasons why she might have felt like fainting either, not enough fluid or not enough oxygen perhaps from the pneumonia. >> what about severity, though? that's what i'm zoning in on here. when you hear pneumonia, severity index for everyday folks like myself, that's pneumonia versus a cold. that's the distinction i'm asking you about. >> a cold is not fatal. for the most part. a cold is not fatal, some viruses can be. pneumonia can be fatal, but, of course if it was diagnosed early, treated early, and in a person that is relatively healthy, you have a good chance of recovering. >> what about age related concerns with pneumonia itself? secretary clinton is and was the most traveled secretary of state ever. in just about every corner of the world here, which means you

also have seen and therefore fought off potentially all sorts of different things. >> she might have a greater immunity if she's been exposed to different types of things. but nevertheless, if you look at cdc charge based on things more like through affect or really harm people who are 65 and above, pneumonia and other respiratory illnesses are up there in the top five. so she would have to take it seriously just based on statistics and the demographics. for the most part, if her doctor is on top of it, destinationed on friday, started early on this, then the severity should be hopefully under control. >> very limited information, only what we have from the statement from her doctor as well as the video you have seen here. in general, what would be, you said, just stay home. that would be the prescription here? and if it is bacterial, you would take antibiotics. is that it? >> for most part. obviously the doctor saw her on friday and thought it was more serious, we wouldn't say stay at home. the doctor would say, you need to be in the hospital if there

was more of a chance of being dehydrated or some other problem. if they saw her and thought it was pneumonia that could be treated with her being at home and out and about, they probably didn't think it was as serious. >> for those just joining us, getting that statement within the last hour or so, from secretary clinton's doctor saying that on friday secretary clinton was diagnosed with pneumonia. and this is after the video earlier that we were watching of secretary clinton leaving ground zero, and then having that difficulty getting into the car. all of that just happening today and that statement just coming into us within the last hour or so. that's what we know at the moment with regard to this story we have been following throughout the day. thank you so much for your expertise and coming up, the clinton campaign says it is not sure now if hillary clinton will make that scheduled trip to california tomorrow. we're going to have a live

breaking news coverage here on msnbc. just joining us, getting you up to date here, hillary clinton's doctor saying that the democratic nominee was diagnosed with pneumonia. this happening on friday, that diagnosis. she became overheated and dehydrated at ground zero at the memorial that happened earlier today. the health of the nominee will be the news this week as well as for donald trump, the republican nominee, he'll be a guest on an episode of the dr. oz show that will air this coming thursday. no doubt talking about his own health as dr. oz will be asking him about that. in the hour long interview. he will address it -- what is expected to be secretary clinton's health based on today's developments. now, last week, donald trump pledged to release his full medical records walking back an earlier promise to only release the documents if hillary clinton did the same.

we're back with our political panel, philip bump, david corn and luciana lopez. one of the things i think that will be asked as we get some polls that came out today, one national poll from the washington post, i'll get philip to give us insight into that shortly, but the question is, when this sort of story develops on a sunday, how this might affect what has already been a very close and tightening race. our polling showing them all tightening in important swing states such as arizona, georgia, nevada, and new hampshire. >> i think at this point you hit on a really important question that we need to ask whenever anything happens, which is is this going to change anybody's mind? and i think it is very hard to know that right now. i think what the doctor said earlier is actually a really

important point. let's see how she recovers from this. if this is something that drags on and on, that's different than something very -- you have bed rest for a day and chicken soup and you get better. i think there is a lot about that is still going to be unfolding. it is a tightening race. we are expecting to see a lot of hard campaigning out there to try to change people's minds. but whether this is the issue that people are going to vote for someone or vote against someone on, i'm still not sure about that. >> that washington post poll showing that 5 percentage point difference now. you've been talking about it, dave has been talking about it, we're going to see a tightening, lose the bump that happened after the conventions. it is going to moderate a little bit. but you dug into the numbers a little bit here. there is interesting pieces behind this. where donald trump gained. >> i think it is worth pointing out that the convention bum i think is gone for now. i don't know that we should now anticipate the trend will continue for donald trump. nate silver had a good analysis

of that yesterday, it has been -- clinton has been fairly flat for a little bit, three or four point advantage, our poll had five, but one interesting thing is that donald trump spent all this time focused on black voters and to some extent hispanic voters but didn't seem to make any difference. republicans came around to donald trump and white people, he gained with white folks, white women with college degrees, a place he was doing poorly. but lost ground with nonwhite voters f you look voters. either way he's still within about five points. >> you look at that within five points and go down state by state and some what were, david, before, preswing states or not discussed as swing states and now they are in that space, our polls in arizona, for instance, showing trump leading 42 to 41 among likely voters.

you got a registered voters, that's a little different. secretary clinton is up 41 to 40. georgia, trump leading there, with likely voters. nevada, clinton up by 1 percentage point and the same is true, up by 1 percentage point in new hampshire, but, you know, the subtext in new hampshire is you know so well here, david, is that has been a stronghold at least in recent paths with the current president. the democratic president and it is looking tough for secretary clinton now and when you look into it, why do you think that's the case? >> it is also looking better in virginia for clinton than people thought previously. i think it is a tight race. she does seem to have an advantage in most of the swing states. or the near swing states. i think it is a good question whether, you know, news like today's news will mack a difference. i tend to think people look at the debate, if there is a

debate, i think there is a small chance it may not be, but if there is a debate in two or three weeks, that will be a big, possibly big moment for people making decisions. and then possibly the subsequent debates. both hillary clinton and donald trump are tremendously well known. they both are very disliked by a majority of americans. so it makes me wonder why people don't know yet if they're undecided. and if they are, what possibly will move them in one direction or the next. so i look at a few of these big moments coming ahead, and look at some of the structural advantages for hillary clinton and say, trump still has to do better to have a shot and, you know, this is a wild race and who knows what else will happen in the next two months. >> the undecideds every year, you're asking that question, why haven't they decided yet. and they just haven't. >> especially with these two candidates so well known, we

lived with for decades. >> why do you think that's the case? it is a very good question from david. >> i think we have lived with the candidates for decades. we haven't lived with them as candidates for the presidency in 2016, for decades. so i think there are a lot of people who are just now kind of tuning in to some of the deeper policy debates, and who are really thinking about these people, not as we have seen them for so long, but really as potential occupants of the white house. and this has been kind of a messy race and we also have got two other candidates in there as well, craw drdrawing votes here there. people are making up their minds, do i vote for one of these other candidates, for hillary clinton, for donald trump. there is still some of that shaking out. for those of us covering this race for the past 16, 18 months, this is what we have lived and breathed. but not everybody lives on twitter or lives and dies by the latest tweet about who is doing

what. >> how dare they? >> as i said earlier, a lot of the undecideds, are, like, i guess i'll vote for that candidate or the other. as they were saying, when we look at the headlines, it is quickly changing, yesterday at this hour, talking about deplorables, right? now talking about pneumonia. talk about the legs of this story. we are -- we do have that first debate and that debate has been called the super bowl, right? that first one. everybody has to be watching it and so this could be very much in the rear view mirror by then. >> we saw what happened to 2012, mitt romney, good debate, surprised a lot of folks, shot up in the polls. but the lesson is he declined after the last debate. i think a lot of this stuff has a fairly short life span, important to cover and talk about, but i don't think it will affect the long-term trajectory. one thing we see is that people don't go from being a hillary

clinton voter to being a donald trump voter, they go hillary clinton to undecided to the other candidate or back to the first candidate. in part because both of the candidates are so unliked, people are spending more time in that undecided area. and it is true. there are more undecided at this point in the collection than there were in 2004 or 12. people don't like clinton or trump, and so they're saying, i haven't made up my mind yet, but to david's point, i think a lot will come home based on things like the washington post poll had donald -- barack obama at 58% approval. that's the sort of thing, the fundamental -- >> we'll finish with you, david, on this one. because of that high approval rating from president obama, he comes out next month and hits the road with the democratic nominee, all bets could be off. >> you compare barack obama as president, and personality and temperament to donald trump. it is night and day. and he's doing very well in approval ratings now, shows people what we want to see in a

president in terms of temperament and intellect. donald trump is the opposite. so that could really hurt because both have such high unfavorable ratings that they the campaign that gets the other candidates possible voters to be disgusted and say home is the one that will win. if the democrats make sure republicans say i can't go with trump, i can't do it, then hillary will win the election. it is kind of sad, but that's probably where we're at. >> that's part of what the deplorables was about, getting the republicans to be, like, i'm not enthusiastic about trump. >> david corn, thank you for joining us. luciana, philip, thank you for being with us. a live report from chappaqua with the latest on hillary clinton's health, that headline coming out as i've been mentioning throughout the hour here of she being diagnosed with pneumonia on friday, learning that within the last couple of hours. also for you, new fighting in syria on the eve of a u.s.

as the united states prepares to elect a new commander in chief, president obama marked the 9/11 anniversary for his final time as commander in chief today at a memorial service at the pentagon. >> we honor the courage of those who put themselves in harm's way to save people they never knew. we come together in prayer and in gratitude for the strength that fortified us across these 15 years. and we renew the love and the faith that binds us together as one american family. >> when the country looks at the fight against terrorism, eight years of obama doctrine included, the islamic state and the conflict in syria are just two of the issues the next commander in chief will now have

to contend with when thinking about that. joining us to talk about this topic is jon klemmens. reuters saying this afternoon that rebels fighting president bashar al assad's regime in syria have expressed concerns about that cease-fire that i was talking about between the u.s. and russia that cease-fire expected to go into effect sundown tomorrow. is this agreement from your perspective a breakthrough, certainly secretary kerry, sergey lavrov working many hours to make it happen. >> i think it is healthy to be skeptical. a lot of other efforts before to secure a cease-fire. i talked to senior administration officials today and it is technically wrong to call this a cease-fire. what it does is it begins a

clock that hopefully from the moment in which the bah stshar assad stops flying his airplane and we have a period of calm, from the period of that, seven days forward so there are seven days of calm and assad not bombing people, then we then move to a next phase in that agreement. the clock begins not from sundown tomorrow, but that's when the possibility starts, but if fighting continues, they wait for a seven day period of calm. it is a soft start, not a hard start monday evening. i think that both russia and the united states want this deal, but trust is not high between either of those parties, nor is it high between any of the parties on the ground in which there are so many different kinds of conflict going on in syria. it is going to be tough to make this work. >> when you look at the details of the deal what does it tell you about the relationship between the united states and russia at this moment?

just a few days ago we had a russian plane fly within ten feet of a u.s. aircraft over the black sea. we have russian harassment of u.s. diplomatic officials in moscow and all sorts of problems with russia. but this is a case in which their interests may overlap just enough so that after the seven days of calm we will sit in a room with russians in a joint implementation center that looks at targeting and do co-targeting with the russians. i think that sergey lavrov and john kerry will be so intensely part of this that they won't allow their own personnel to be unprofessional or to deal with each other badly. you can't walk away from the fact that u.s. and russia relations just about everywhere in the world are frayed and tense. this could have the opportunity of not just getting syria right and the united states and russia more on the same page it could become an opportunity for detoxing some of the rest of the relationship in the world.

>> on this 15th anniversary of 9/11, just showing video of president obama there at the pentagon, the last time as a sitting president on this commemoration dated what do you think the legacy of president obama will be with regard to syria and the region and what he wants it to be? >> i think that this administration from president obama through the various national security and defense -- it is very uncomfortable about syria. it is a box they can't check off. it is a civil war with a proxy conflict that is stuck on top of it. they're never going to be able to say we put this in the right place. we're leaving. and the tragedy and nightmares of that have been solved. i think he wish i could have, i think he knows, you know, way down the road, we're talking perhaps decades, we may look back and say what a nightmare, black hole of resources this was. and perhaps president obama will get rewarded for showing strategic restraint of knowing this nightmare was not the thing

to throw more u.s. forces and personnel lives into. that kind of reward from history takes a long time. it will be a painful blight on the administration. >> thank you so much, steve. back to our breaking news we're watching this hour, the clinton campaign saying it is not sure if secretary clinton, hillary clinton will mack a scheduled trip to california tomorrow. this is after secretary clinton left a 9/11 memorial event earlier at this day here as they were saying in her campaign saying she became overheated. her doctors then saying she was diagnosed with pneumonia on friday. morgan radford is in chappaqua. you were there when secretary clinton returned to her home. that's where her doctor met her, we didn't necessarily know until that statement came out morgan. >> we didn't know at the time. we do know now she was assessed
