king of shock tv morton county jr. in a cnn film called "the evocateur." my colleague wolf starts right now. hello. i'm wolf blitzer. it's 1:00 p.m. here in washington. 9:30 p.m. in tehran. 1:30 a.m. friday in pyongyang, north korea. wherever you're watching from around the world, thanks very much for joining us. right now a federal judge is hearing arguments about state department e-mails involving a top aide to then secretary of state hillary clinton. the case could shed some new light on the controversy surrounding hillary clinton's e-mails. cnn's evan perez has been following the story and is with me in the studio. what's the very latest? what are you hearing about what's going on? >> this is a controversy that speaks to a lot of federal workers who are wondering how this relates to them and this is a lawsuit over records related to a special adviser to hillary

clinton back when she was at the state department and now in the campaign. there is a bunch of different issues at play. one of them has to do with whether or not she was double dipping, the accusation being made. she was a special government employee in which she was able to work outside of the state department and collect money both as a special government employee and whatever consulting contract she may or may not have had at the time. and so this is a lawsuit about getting records of that work that she was doing at the time when this was filed the state department said we don't have that many records. it turns out the reason for that was because hillary clinton had a private e-mail server that contained a lot of the messages, the e-mails, that are at issue in this case. >> and these e-mails, the controversy continues and a longtime aide to then-secretary of state, even when she was first lady, an aide to the current candidate hillary clinton. she's very close to the former secretary of state.

the e-mail question was dated back on april 10, 2011, an e-mail was forwarded about the then-u.s. ambassador chris stevens in libya about dangers he was confronting whether they should move out and subsequently some u.s. intelligence officials thought that e-mail should have been classified. >> right. and this is an e-mail on a separate matter, we should be clear. this is one of the couple of e-mails that the intelligence community saw when the state department was trying to release it in may earlier this year and said, wait a minute, there's some classified information here. and so they asked to take a deeper look. and so we now know this is one of the e-mails, this 2011 e-mail forwarded to the secretary of state to her private e-mail server, one of the ones that raised a lot of concerns in the intelligence committee and now has gotten us to this controversy. the campaign has said, look, this is an example how the intelligence community is really

aggressive in misclassifying, overclassifying information, things that shouldn't be classified. let's take a closer look at this e-mail, the 2011 e-mail in particular. it describes in one portion how they're making plans for checking out of hotels and they're going to check whether they should evacuate benghazi, a year before chris stevens and others were killed in the attacks. later it describes that one of the plans is possibly returning to greece. again, part after sensitive piece of information. when it was sent, it's sensitive because it describes basically evacuation plans for chris stevens and the americans there in benghazi. that's what is at issue here. that's why the intelligence community decided that they felt this stuff should have never been sent to a private e-mail server and that's why this controversy will continue to dog this campaign. >> all right.

we'll stay on top of it. evan, thanks, very, very much. the clinton campaign has been dogged for some time now over hillary clinton's decision to use a personal e-mail server while she was secretary of state over four years. joining us now from new york is the communications director for hillary for america, the hillary clinton campaign, jennifer is a former white house director of communications for president obama. thanks very much for joining us. so give us your perspective on what's going on, i guess this decision to question at least in court huma abedin you know well who has been close to the secretary for a long time. what's going on here from your perspective? >> i think there are a couple of things in the report that evan just did about that particular e-mail that i think is worth highlighting because what we think that shows that sort of illustrates for people how arcane the process on classification will be made

public can become. that e-mail wasn't sent by huma abedin, it was sent by a service officer and it was marked sensitive but unclassified. this is a case where not only did the state department say it was not classified at the time, it was specifically marked as unclassified. >> one second. you're absolutely right. the original e-mail was sent to davis to jake sullivan, huma 6 abedin and some other assistants to the secretary of state. abedin forwarded this e-mail from her state.gov e-mail account to the secretary of state's private e-mail account. that's what huma abedin did, right? >> that's right.

it was eventually forwarded on. it was marked sensitive but unclassified. the state department has deemed it -- has always believe d it t not be classified material. it has been sent to the hill on one occasion, put on the state department website as public information because they didn't think it was classified. later other agencies have come in. now that the e-mails are all going to be made public, other departments outside of the state department are getting involved to determine if they think that they have equities here about why something should be classified. our point is what i think there's a lot of questions about this, some of the reporting around is confusing. why we are trying to educate voters more on this is to understand a couple of key core concepts here. "a," that using personal e-mail accounts that's not unprecedented. other secretary of states have done it. it was permitted at the state department guidelines at the time. it wasn't until 2014 after

hillary clinton left the state department that they said people should default to a dot-gov address and she said she would do it differently, if she could have it to do over again. she never sent or received e-mail that was classified at the time, and now that the state department agrees with that and other departments are getting involved, because the e-mails are being made public and that is why we're going through this process we're going through now. we want to explain this to everyone and have them understand what the process is. it's not as if we didn't expect this to happen. it's republicans taking this issue on the campaign trail on capitol hill and making it -- trying to make it a partisan issue. >> why did she decide to delete half of the e-mails she effectively engaged in during her four years as secretary of state? >> she had her -- what happened

was state department came to all the former secretaries of state last fall to ask for whatever records they may have because they realized that they didn't -- because not just hillary clinton but other secretaries of state had used personal e-mail they may not have captured everything. she asked her lawyers to look at this, she had some legal minds on the case, to see which e-mails were state departments and which were personal and turned over the state department ones. anything that was business related. and then chose not to retain the ones that were considered personal. >> on that point, why wouldn't she want to keep her personal e-mail records? maybe there were fun, cute e-mails she would want to keep. why would she want to wipe that clean? >> these are personal e-mails and i think everyone understands even hillary clinton gets a zone of privacy. she decided that she retains a couple months' worth of e-mails

so she can find personal e-mails she needs to but after that she doesn't need them anymore. she made this decision. i think obviously she was former secretary of state so we want to make sure people understand how she handled classified information when she was secretary of state, that she was careful with it, she didn't deal with it online. she dealt with it hard copy, in meetings, not on the computer. at some level this is not different than the situation with governor bush. he had a personal e-mail account. he had his own server as well. he decided which were business related that he would make public and which were personal that he wasn't. at some point with e-mail everyone makes these determinations, and we want people to understand what the facts are but then look at this in a broader political context. you see republicans on political, on the campaign trail trying to divert attention from issues that aren't going so well for them whether it's the

economy or immigration or women's health and trying to hurt hillary clinton this way. as your own poll shows she is quite durable. >> there's some disturbing new poll in quinnipiac university poll today that shows only 32% of respondents in florida said hillary clinton was honest and trustworthy. only 34% of respondents in ohio, a key battleground state, thought she was honest and trustworthy. these are pretty disturbing numbers. >> i'm not sure why quinnipiac continues to do this, but their sample is they consider particularly in florida that they imagine there are going to be nine percentage points more republicans turning out than the electorate in 2012 and i think with ohio they had eight percentage points more. yes, if the republican -- if people who vote on election day are 10% higher in the republican category, democrats probably

aren't going to do very well. your own poll, wolf, this is something i have to say over and over again because it's remarkable how the coverage doesn't reflect this but your own poll shows that she beats every republican candidate and she has the higher favorability rating than every republican candidate. she is come under a lot of attack, gets attacked by 19 candidates every day. she continues to go out and put forward her own message on how she would help middle-class families on the economy. i think she does well because it's clear she's the most qualified to be president, that she understands what people's lives are like, that she's going to fight for them. she continues to do well. the truth is the polls back up that she's quite durable and continues to be people's leading choice to be the next president of the united states. >> our current poll shows that republicans are now more enthusiastic about voting than democrats are, that potentially

could bode ill if she gets the democratic presidential nomination. one final question, this new quinnipiac poll shows that joe biden, the vice president, would be at least equally xcompetitiv against republican candidates in florida, ohio, and pennsylvania as the secretary of state, the former secretary of state, would be. here's the question. how worried are you about joe biden jumping into the race? >> as you know, we have -- i do have a lot of love and affection for the vice president and will let him make his decision. he's the sitting vice president. he obviously would be somebody we think would have a lot of support, would be a very serious candidate. but we're going to -- i know that he's going through the process to make a decision and we'll see what that is and everyone will respect it. he's the sitting vice president. he would be strong. >> he certainly would be. let's see what he decides. jen palmieri, thank you for joining us. still ahead, the gloves come

off in the race for the republican nomination. also coming up, former president jimmy carter now saying his future is in god's hands. what he revealed today about his cancer diagnosis and now he plans to tackle the disease. big day? ah, the usual. moved some new cars. hauled a bunch of steel. kept the supermarket shelves stocked. made sure everyone got their latest gadgets. what's up for the next shift? ah, nothing much. just keeping the lights on.

former president jimmy carter is beginning targeted radiation treatments today after announcing melanoma found on his liver has spread to four spots on his brain. here's how the former president described the moment he first got that news. >> first i felt that it was confined to my liver and the operation had completely removed

it, so i was quite relieved. and then that same afternoon, we had an mri of my head and neck and it showed up that it was already in four places in my brain. so i would say that night and the next day until i came back up to emory i just thought i had a few weeks left but i was surprisingly at ease. i've had a wonderful, full life, thousands of friends and i've had an exciting and adventurous, gratifying existence. i was at ease, much more so than my wife was. but now i feel this is in the hands of god. i'll be prepared for whatever comes. >> for more on president carter's diagnosis, let's bring in cnn's dr. sanjay gupta joining us live from the carter center in atlanta. sanjay, obviously very sad development. jimmy carter says doctors still don't know where the melanoma originated. he says that they expect more cancer to appear in other parts of the body. he's 90 years old.

so what are his options for treatment? what is his prognosis? >> reporter: his options for treatment are a couple of things. one, he's going to get a type of chemotherapy drug and these options were laid out for him. he said he listened to the advice of his doctors. the chemotherapy drug is a drug that empowers your immune system, makes it stronger, better able to fight the cancer, and he's also going to start this afternoon, wolf, radiation therapy to the brain. these four areas of the brain that have evidence of melanoma, radiation is a good option there. it's something he's going to have to do every couple of weeks for some time. that's the plan. between conversations between the former president and his doctors. >> he was asked about his family's history of cancer, sanjay. his father, three siblings all

had pancreatic cancer. his mother had breast cancer. here is what he had to say about that. listen to this. >> there is some genetic challenge from the pancreatic cancer. whatever the doctors recommend for blood tests as a precautionary member for the other family members put into effect. >> so what about this family history? how does that play out presumably as far as his cancer is concerned especially given his advanced age, he's now 90, almost 91 years old? >> reporter: it is an extraordinary family history. every one of his relatives had pancreatic cancer, his parents, his siblings. they all died of cancer as well. that's always been a concern for him. he was getting regular

screenings because of the concern he would develop pancreatic cancer as well. if you're going to develop pancreatic cancer because of a hereditary problem, it's likely he would have developed that much earlier in life. instead at age 90 he has developed this melanoma. he doesn't have, at least that we know of, evidence of pancreatic cancer. they're probably unrelated, remarkably. he's got aten a different cance because of his age and damage to his skin perhaps at some point. that may be unrelated to the pancreatic cancer. his children, grandchildren, great-grandchildren, they'll probably need to get genetic testing to find out if they have some of these mutations as well. >> good advice, sanjay. we just got a tweet from president obama and he said this. president carter is as good a man as they come. michelle and i are praying for him and, rosalynn, we're all

pulling for you, jimmy. we're pulling for the former president jimmy carter as well. up next, donald trump says jeb bush is unelectable. bush says trump is not a true conservative. we're going to give you a ringside seat as they battle it out in dueling town hall meetings. when you have a migraine, you'll reach for anything to make the pain go away. truth is, most pain relievers don't work like excedrin migraine. it relieves my pain starting in 30 minutes. that's fast! plus, sensitivity to light and sound. excedrin migraine. wow, that was fast.

presidential politics now, the gloves coming off in the fight for the republican nomination. the battle is symbolic of the fight under way for the white house and the future of the republican party. sarah murray gives us a ringside seat. ♪ no, we ain't going to take it ♪ >> reporter: step aside manny

pacquiao and floyd mayweather. >> thank you, thank you. >> reporter: donald trump and jeb bush are taking over the ring. in a night of dueling town halls in new hampshire, just 15 miles apart and within an hour of each other, both threw jabs. >> i don't see how he's electable. jeb bush is a low energy person. for him to get things done is hard. he's very low energy. >> mr. trump doesn't have a proven conservative record. he was a democrat longer in the last decade than he was a republican. >> reporter: though bush set the date for his town hall first, his crowd of about 200 got walloped by trump's 1,200. >> we have a lot of people outside, hundreds and hundreds of peep standing outside. >> reporter: some even standing in an overflow room to see the candidate in his first official town hall. >> you know what's happening to jeb's crowd right down the street?

they're sleeping. he's gone down like a rock. >> reporter: it seems wednesday was the night bush came out of his shell throwing this punch at trump's immigration policy. >> hundreds of thousands of dollars is not a conservative plan. >> reporter: a blow the gop front-runn front-runner blocked telling reporters -- >> they're going up and down like yo-yos. i'm not going anywhere, folks. i'm not doing this for my health. i'm doing this to make america great again. >> reporter: florida's former governor doesn't think that's enough to win the fight. >> people are going to want someone sitting behind the big desk that they know their compass points north, that they have the integrity to act on what they say they'll do and they have the leadership skills to make it so. that's it. >> sara murray reporting for us. where do they stand toe to toe? a new poll shows donald trump

beating both jeb bush and marco rubio, get this, on their home turf in florida. the quinnipiac university poll shows trump would get 21% of the vote in florida among republicans if the election were held today. bush comes in second with 17% followed by rubio and ben carson at 11% each, 8% undecided. on the democratic side in florida once again hillary clinton leads bernie sanders 48% to 15%. the vice president, joe biden, who is an undeclared, unannounced, still undecided candidate, at 11%. 17% of democrats in florida undecided. still ahead, he's trailing in the polls but a former new york governor george pataki is promising a long haul fight for the republican nomination. he's standing by live. we'll speak with him about his strategy to take on donald trump and the other republicans, why he thinks he's the party's best hope in the general election. if you have moderate to severe plaque psoriasis.

the republican presidential front rner donald trump says he's the only reason other candidates are even talking about immigration. he's also been sparring directly with jeb bush over several policy issues. only moments ago the former florida governor spoke about immigration after his town hall in keene, new hampshire. >> we are a diverse country. that's a virtue, a strength of our country. i'm proud our children have a mexican-american mom, as american as anybody else. loves this country as much or as much as anybody else, believes in the shared values of this great country.

my children are blessed to have that heritage. >> what led her to that? >> she wanted to vote for my dad and she loves this country. she wanted to share the experience with me. this is what families do all the time. it shouldn't be such a novel thing, to be honest with you. this is pretty regular in the places where i grew up and where i live now. this whole immigration debate is hurtful for a lot of people, really hurtful. i'm talking about in general when you just huge tidal wave of accusations or bombastic talk. there's a lot of people that share the immigrant experience and what they hear is you don't think i'm part of this, part of this country. i know that for a fact because i have hundreds of people that tell me that. we need to talk about solutions

and get on with fixing things in this country and turn this into a driver for success rather than defeatist attitude we have. >> do you regret using anchor babies on the radio? >> i don't regret it. do you have a better term? >> i'm asking you. >> you give me a better term and i'll use it. i'm serious. don't yell at me behind my ear, though. give me another word. [ inaudible ] that's not another word. that's a seven -- look, here's the deal, what i said was it's commonly referred to that. i didn't use it as my own language. you want to get to the policy, i think people born in this country ought to be american citizens. >> i notice your brother sent out an e-mail today.

>> yeah, he's for me. >> you remind us you're your own man but you're having him work for you. >> is that a contradiction? i have my own record, my own life experience. i'm blessed to have -- over and out. >> you are trailing trump here, also in withashington. he said your crowd was sleeping. how do you respond to that? >> that's an insult -- >> the narrative your campaign lacks. >> you're repeating the echo of the narrative. if you went to the event you would have found there was a lot of enthusiasm. and there's a big difference. i'm a proven conservative with a record. he isn't. i've cut taxes every year. he's proposed the largest tax increase in mankind's history. i've been consistently pro-life. he, until recently, was for partial birth abortion. i never have met anyone who

thought that was a good idea. i believe we need to reform our health care system to stop the suppression of wages and have access to inshurn. he's for a single pair system. he actually advocates these things. he's been a democrat longer than a republican. i just think when people get this narrative, whatever the new term is, the compare and contrast narrative, they're going to find that i'm going to be the guy that they're going to vote for, and it's a long haul, man. whoa, whoa, whoa. yes, ma'am? yes, ma'am? >> all right. so there you get a flavor of the q&a the former florida governor has been having with reporters in new hampshire. let's get the perfespective of e former governor of new york, george pataki. thank you for joining us. give us your reaction to what you heard from jeb bush. >> wolf, i think the whole thing

is ridiculous. we're talking about what term you use to describe children born in america. the world is falling apart. iran is on the verge of having an illegal nuclear program. isis poses a threat to us here in america. our economy is not growing and we're arguing back and forth about utter nonsense. i think the whole donald trump thing has been not just a distraction but it's demagoguery when americans understand we need a leader who can bring us together and actually solve problems. >> why is he doing so well in all the polls and you're not? >> i think the american people are angry, and i understand that. i'm angry, too, about a government that doesn't stand up for america in the globe, that doesn't understand too many american families are hurting and, by the way, wolf, right now in washington it is a corrupt insider system. people are angry at that. donald trump has tapped into that anger and focused it now on immigrants, which i think is tragic and bad for america, but ultimately it's not about being angry. it's about turning that anger

into positive solutions that's not what trump has done. it is what i would do. >> he recently tweeted this, governor pataki was a terrible governor of new york, one of the worst, would have been swamped if he ran again. that is one of the tweets he had attacking you. what's your response directly to him? >> i'm part of the crowd. i think he's pretty much attacked everybody and, by the way, when i was governor i can't tell you the number of times he told me i was a great governor. we shouldn't be discussing donald trump's tweets. we should be discussing the idiotic policy he's advanced where he's going to say, for example, 7, 8, 9-year-old child born in america sitting in a third grade classroom, we're going to send thousands of police or soldiers or something into that classroom, take that child and send it to a country they've never been to where they may not speak the language because their parents don't have the right papers. this is not america. this is demagoguery. we have to move beyond this as

republicans and as americans and understand that if we work together and look at solutions, the best for this country should be ahead of us, and i know that it is. >> so you agree with a lot of scholars who say that if a child, even a child of illegal immigrants is born in the united states, even if the mother slipped into the united states simply to have the child born in the united states, that child is a u.s. citizen, you agree with that position? >> first, i think it's wrong that we let that happen but, yes, that child is a u.s. citizen. and it's just ridiculous to me that not just trump but others in my party, scott walker and others, agree with trump. think about it. we're going to send soldiers, troopers, whatever, to round up 11 million people, drag them off the farms, drag them out of a business, drag kids out of school and send them, often in the case of kids who may have been here 9, 10, 11 years and never lived in the country their

parents came from and send them back? we should be focusing on standing up to radical islam, on growing our economy and creating jobs, on changing the corrupt system in washington. donald trump is not part of the solution. he's part of the problem, wolf. >> governor pataki, thanks very much for joining us. >> thank you. >> for the latest on politics and a lot more on all the presidential contenders go over to cnnpolitics.com, an excellent source for new information. coming up, north and south korea, guess what, they're exchanging fire with threats of more violence. we're going there live. we'll have a report on what led up to these very tense moments on the korean peninsula where 30,000 u.s. troops are along right now.

tensions are ratcheting up right now between north and south korea. the latest incident both sides exchanged fire across the heavily fortified border. relations between the two sides have been increasingly strained in the past few weeks after two south korean soldiers were wounded by land mines propting south to resume blaring propaganda messages across the border. brian todd is joining us now. he has more on how all of this began to unfold. what are you learning? >> reporter: we've been speaking with u.s. and south korean officials about how all of this did unfold. a u.s. official tells us north korea first today fired at least one shot, a south korean official says that was assumed to be a rocket toward a south korean loudspeaker system that was blaring propaganda messages toward north korean soldiers across the dmz.

according to a south korean ministry official that one shot was assumed to be a small rocket. a u.s. official says south korea responded by firing 36 artillery shells toward the north. now there's no word yet on whether that caused any casualties on north korea's side. this is an escalation of tensions that were already very high. this week the u.s. and south korea began an operation of massive military exercises, some 30,000 u.s. troops and about 50,000 south korean troops are participating. some of the live fire drills are scheduled to take place later in a city right about there near the dmz that could be seen as a possible provocation to kim jong un. kim's regime made a threat implying a possible nuclear attack on the united states. u.s. officials and weapons experts say they don't have the capability of launching that

kind of attack right now but they are working on it. now much of this recent tension can be traced back to august 4th when that attack, as wolf mentioned a moment ago, a land mine, blew up on the southern end of the dmz right about there on the southern end. two north korean -- two south korean soldiers were nearly killed in that attack. u.s. and south korean officials say the north koreans deliberatedeliberat deliberately planted those mines. that gives you a sense how tensions have been building at least since august 4th in and around the dmz. >> let's get more perspective on what's going on. gordon chang is joining us, the author of "nuclear showdown." he's a columnist with forbes.com. gordon, thanks very much for joining us. as you and i know if you've been watching the korean peninsula for years, there have been serious shelling exchanges like this before. is this time different? >> this time is a little bit

different because, you know, north korea engages in pro-v provocative behavior but rarely do it when the u.s. and south korea are at a high state of readiness. as brian todd pointed out, we have these freedom guardian exercises which means we are at that high state. this really means that north korea, one of two things, either it's not serious or there's a lack of coherence. >> is this tension right now the result of these u.s./south korean military exercises which the north koreans obviously hate? >> i don't think it has anything to do with the exercises. kim jong-un, the ruler of north korea has probably killed 3 or 400 junior officials. there's a lot of disunity at the

top of the regime and kim jong-un has problems with the military and most of this instability is caused by him trying to take back power and money from the military. you put all of that together and that's why we're seeing this exchange of fire at this particular time. >> south korea's relatively new president said to be ready for stern response to today's events. how likely is she going to allow this to escalate? >> right now there's a 2013 plan of counter provocation, which means that the south korean military, at a very low level, has the authority to fire back at north korea which is the reason that we saw the 36 shells being fired at the north. this really changes the dynamic. it doesn't really matter what president park or president obama says. there's going to be an automatic response. the reason we have this, there

was no response in 2010 when the north koreans killed the 46 in the south korean frigate in march of 2010. that's why we'll see a different dynamic with basically retaliation. >> i remember that very vividly. shortly after that, i went to pyongyang for six days and it was an extremely tense time. it calmed down in the period after that but at that time it was very tense. there's still some 30,000 american troops stationed along the demilitarized zone between north and south korea. maybe a million south korean troops and maybe a million north korean troops. north korea obviously has nuclear capability as well. this is an extremely dangerous peninsula right now. gordon chang, thank you.

>> thank you. will iran be able to carry out its own inspections at one of its sites? plus, new numbers of what the americans think of the new deal with iran.

the state department is downplaying a report of a secret side deal to the iran nuclear deal according to the associated press iran will be able to allow its own inspectors at a military site where suspected nuclear work may have taken place but the obama administration says iran won't be carrying out those inspections alone. let's bring in our chief national security correspondent jim sciutto who has been reporting on this. jim, what do we know about the reported deal between iran at the iaea? >> this is what u.s. officials have told me. this is a military site. this goes to what they refer to as the past military dimensions

of iran's program. did iran in the past try to build a nuclear bomb? that is the key question here. this has been a long issue because the feeling has been that iran has not completely fessed up. iranian inspectors, in effect, will be doing the inspecting on their own and handing the samples back to the iaea. i'm told by a senior state department official that's not the way it will work. they will be taking part but under the oversight of the iaea. based on past practices, this is something that they've been doing a number of years for a number of countries. either they will be present there or watching on video camera and they would, of course, test the material picked up there. from the administration's point of view, yes, iran is involved but iran is not doing this on their own. >> in a brand-new cnn orc poll,

56% of americans think that congress should reject the deal, up from 52% in july. 44 in july said they should approve the deal and now 41%. those are numbers that the administration doesn't want to hear. >> no question. and coming out on both sides of the aisle, republicans certainly but also democrats and powerful democrats, robert menendez among them that's reflecting those questions. and questions like this, you know, when you get into the details of this deal as you see what these iaea inspections, there's a lot there that gives ammunition to the critics to say this is not an agreement we would have made and that now the administration comes back and says it's the best deal possible and the alternatives were no bett better, in fact, worse. people are expressing opposition

leading up to this next important vote. >> only 38% approve of the way the president is handling the u.s. relationship with iran. 60% disapprove in our new poll. we'll leave it there for now. i'll be back at 5:00 in "the situation room". "newsroom" with poppy harlow begins right now. >> hi, everyone. i'm poppy harlow. i'm filling in for my good friend brooke baldwin. we start with the u.s. president as humble and candid as he ever has been before, opening up about the cancer diagnosis that left him thinking he just had weeks to live and also his legacy and his biggest regret. telling the world that melanoma has spread throughout his body and four spots were found on his brain. but at 90 years old, he's still got a lot of fight in him and he
