nobles and mike warren, we have learned that the committee subpoenaed short a few weeks ago. but that unlike some other trump officials, he's not fighting the subpoena. and, anderson, short's cooperation is a significant development because he is, as you say, a firsthand witness to so many critical events. he was with mike pence at the capitol on january 6th. he was also in the oval office on january 4th when former-president trump tried to convince pence not to certify the election results. so, um, all of these things our sources say add up to one thing. short's assistance signals a greater openness among pence's inner circle with one source telling me the committee is getting, quote, significant cooperation with team pence. just for context, short is considered one of pence's most loyal aides. it is hard to imagine that mark short would cooperate with the committee without pence's blessing. >> so, i mean, this is kind of a new divide in how the former president's team is dealing with the committee, versus the former vice president's team. what kind of information or documents would short likely be able to provide? >> absolutely. so, mark short knows what was going on in the days leading up to january 6th, like what happened in the oval office. he knows what happened at the capitol on january 6th. it's likely that mark short -- who was chief of staff to mike pence -- was not calling or texting. maybe someone like mark meadows who was chief of staff to donald trump when the riot was going on. asking him what's happening? why is -- you know, why is no one stopping this? so, short is likely to be able to provide key information about conversations, phone calls, texts. things that happened in real-time on january 6th. also, perhaps he can answer two of the most important questions the committee has. what was donald trump doing when was riot was going on? and why didn't he move more quickly to take action to stop it? >> and what are your sources telling you about the motivation behind people in pence's inner circle who are maybe cooperating? i mean, and -- and also, obviously, how the former president is either reacting or likely to react? >> right. so, the pence team motivation is interesting because we've seen pence separate himself from trump. sort of come back to trump. then, say i did the right thing on -- on january 6th. he has indicated he wants to run for president. maybe, he sees this as a way to muddy up trump, to get a different lane in the republican base. as for donald trump, let's face it. he is not going to be happy with this, to say the least. and he has a history with mark short. in fact, on january 7th, trump banned mark short from the white house because he was so angry that pence didn't do his bidding, anderson. >> jamie, stay with us. i want to bring in "washington post" associate editor bob woodward, who has written along with robert costa about the moments and people in question in their new book "peril." also, cnn political director david chalian joins us. bob, you heard jamie's report. obviously, a big part of your book was devoted to january 6th and the events that led up to it. how big a deal is it in your view mark short who is cooperating with the committee? >> you couldn't get a better source when you do these investigations, you are always looking for somebody who would be labeled the reliable witness. and mark short joined at the trump -- at the -- at the hip with pence in a very significant way. the chief of staff in this political environment is the alter ego, to a certain extent, the conscience of the principal. i think an important element here is that pence and short share deep religious conviction. and on january 7th -- after the insurrection, the day after -- when pence certified joe biden as president and the house and the senate went through that significant really pivotal moment of saying joe biden is the president, short sent -- and -- and this is important -- pence a quote from the book of timothy from the bible. saying i have fought the good fight. i have finished my course. i have kept the faith. so, somebody like short is there at key moments, is always getting reports from pence in -- in our book if you just look under mark short and pence, you see they are together at critical moments. so this opens a big door. >> and, david, i mean, you know, as bob was saying, pence -- short has been incredibly loyal member of the pence team for years going back to the congress -- congressman pence's days in the house. is it -- i mean, it's not just, david, potentially you know his opinions that -- that he has access to. it's documents. >> yeah, there is no doubt about that. and -- and -- and at critical junctures in this timeline that the committee is putting together. i mean, who more is going to have firsthand knowledge about the pressure campaign from trump onto pence than mark short who witnessed it firsthand? i will just note your -- i'm glad you raised their history, anderson, because this gets at jamie's earlier point. it's not only hard to imagine, i -- i think it's nearly inconceivable that mark short would do this without the tacit approval of mike pence. would do this without the tacet approval of mike pence. you mentioned he was the chief of staff in the house republican conference for pence back in the very early years of the obama administration. he served with -- he served with him during the 2016 campaign when trump put pence on the ticket. and then of course, went into the white house and served as his chief of staff. this is a longtime loyal aide. he is doing this, of course, with pence's approval. it's -- it's just inconceivable to think otherwise. >> and, jamie, i mean, you have reported in the past that there are some members of the pence team who are more willing to testify than others. if mark short does indeed testify in front of the committee, are there others who would possibly follow suit? >> so, we know from reporting a couple of weeks ago that there are at least five members of pence world that the committee is interested in talking to. and one of those was greg jacob, who was pence's counsel. who was also in the oval office when trump was pressuring, um, pence. i think that there are a number of people and my reporting is that the committee is feeling more and more confident that more people from the pence inner circle will cooperate. >> bob, the fact that mark short was physically alongside then-vice president pence on january 6th as, you know, people are chanting "hang mike pence" which the former president recently described as -- as, you know, a common-sense reaction because they were so upset and angry. are you surprised the committee needed a subpoena to get short to cooperate? or do you think that's part of getting him to cooperate was, look, i want to do this but you need to subpoena me? >> well, you -- you don't know the answer to that very important question. though, what -- what you do know is -- and what we tried to show in our reporting -- is that pence, though the loyal, dutiful, vice president to trump, there was always an independent streak here. and the group that jamie's referring to around pence -- a lot of lawyers, political advisers, people always saying to pence you need to strike out on your own. preserve the position you have. 61 years old now, i think. and certainly, wants to run for president, would like to be president. and -- and so, this is a -- a foot in the door. and something i -- i know if you go back to other investigations, the chief of staff is always the key person. there's no one like it. in fact, it's almost better than the spouse. it really brings you face to face with the daily forces, the -- the pressure campaign on pence was intense. and no one would know the details more than mark short. >> anderson, i would just say that pence, this year, i think about the preserve bob's talking about has been all over the map on this. it's not clear that he is positioning himself so independently of trump. i mean at one point, just in recent months, he described january 6th as just one day in history that the media's obsessed about. at other times, he's said the obvious, that he and trump are never going to see eye to eye on that day. i would imagine so. one person was inciting an insurrection. the other guy was hearing hang mike pence while he was presiding over ceremonies at the capitol. of course they won't see eye to eye. but it is not yet clear exactly how pence is going to try to navigate a path forward if he does run for 2024 that is one independent of trump. we all saw his four years as that loyal vice president. it is going to be so difficult for him to have an identity apart from trump's in a republican nominating race in 2024 if that's what comes to be. >> david, you're exactly right. but -- and -- and pence was one way and the other way. he was with trump. he was defying trump. but in -- in the end, and, you no, this is the end of this ball game -- pence did the right thing. >> no doubt about it. >> he stood up to trump. and in the meetings we report with trump, it -- it was interesting. pence was always saying to trump, i'm praying for you. i continue to pray for you. and that's a signal of the religious component and it's a signal you know who you do pray for the most? the sinner. >> be interesting to know what the former president, you know, how much comfort he took in the knowledge that mike pence was praying for him. perhaps, he will write about that one day. bob woodward, jamie gangel, david chalian, thank you so much. appreciate it. coming up next, with funerals planned this week for those killed at oxford high, there are new developments in the case against the shooter's parents, including a search warrant executed tonight. also, this evening as russian troops build along ukraine's border, the stakes for tomorrow's biden-putin video call could not be higher. what president biden may do to try to head off a feared invasion, his options if tanks start to roll. and the stakes for the western alliance. we'll talk to cnn's fareed zakaria about all that. of getting hiv through sex. it's not for everyone. descovy for prep has not been studied in people assigned female at birth. talk to your doctor to find out if it's right for you. descovy is another way to prep. descovy does not prevent other sexually transmitted infections, so it's important to use safer sex practices and get tested regularly. you must be hiv-negative to take descovy for prep. so, you need to get tested for hiv immediately before and at least every 3 months while taking it. if you think you were exposed to hiv or have flu-like symptoms, tell your doctor right away. they may check to confirm you are still hiv-negative. serious side effects can occur, including kidney problems and kidney failure. rare, life-threatening side effects include a build-up of lactic acid and liver problems. the most common side effect was diarrhea. tell your doctor about all the medicines and supplements you take, or if you have kidney or liver problems, including hepatitis. if you have hepatitis b, do not stop taking descovy without talking to your doctor. ask your doctor about your risk of hiv... ...and if descovy for prep is right for you. get help paying for descovy for prep. learn more at stepupprepup.com. hi. so you're the scientist here. does my aveeno® daily moisturizer really make my dry skin healthier in one day?

>> anderson, we know that search warrant was executed for any and all electronic devices found in the home. that 65-year-old voluntarily showed up at the oakland county sheriff's department with his attorney. his attorney releasing a statement just moments ago saying his client -- the 65-year-old -- had no idea there was a warrant out for the arrests of the parents. he also said he did not help those parents evade police, and he didn't know they were arrested at his art studio. >> not guilty. >> not guilty. >> reporter: today, jennifer and james crumbley now sit in the same jail as their son. all, under close observation. the parents were arrested early-saturday morning. found in a warehouse in nearby detroit hours after they were charged with four counts each of involuntary manslaughter. >> if there are fugitive of justice charges that could be additionally added if they are convicted, there are actually additional points that are scored for the obstruction of justice. and so, they are likely to get higher sentences. >> reporter: prosecutors saying the crumbleys were making preparations to flee during the time they evaded capture. >> they withdrew $4,000 from an atm in rochester hills. they fled, and they -- they sought multiple attempts to hide their location and were eventually tracked down and these two individuals were found locked somewhere in a room hiding. >> reporter: a third person, the man who allowed the couple to get into the warehouse, was interviewed by the oakland sheriff's department. a search warrant was issued for electronic evidence at his home but still no word on whether he will face potential charges. >> clearly, somebody helped them into that location and made it available to them. and it was after it was publicly announced that there were warrants for them. >> reporter: both, jennifer and james crumbley have pleaded not guilty to the charges and their attorney took issue with the timeline of events laid out during their arraignment. >> the facts that -- that have been presented by miss mcdonald and her office have been cherry picked to further her narrative of making an example of mr. and mrs. crumbley. >> none of this should have happened. a 15 1/2-year-old should not be sitting in jail facing life in prison. and it could have been prevented. >> reporter: the prosecutor is still investigating the school's role in the events leading up to the shooting. >> i just think it's time we start -- stop talking about how terrible it is that we have school shootings, and look to see what we can do to actually prevent them from happening again. >> reporter: the michigan attorney general has also criticized the oxford school district's hiring of a third party to investigate the shootings and offered to help conduct a review of the events that day. meanwhile, a community is still grieving the death of four teenagers and rallying around those injured in the shootings. the detroit lions dedicating its first win of the season to all the victims. >> this game ball goes to the whole oxford community. all those who were affected. i want us to not forget these names. madisyn baldwin, hana st. juliana, justin shilling, tate myre. those names will never be forgotten. >> so adrienne, what more do we know about the parents facing additional charges about the manhunt required to bring them into custody? >> anderson, it is possible they could face additional charges, for example, obstruction of justice. that is according to the state attorney general but she did underscore she is not handling this case. if those additional charges come, it will be up to the prosecutor. keep in mind, this couple is already facing a higher bond rate because of their actions. meanwhile, less than ten miles from the high school, a visitation took place earlier today for the 16-year-old who died in the patrol car on the way to the hospital. we learned a little more about tate. today, we learned he loved the holidays, especially christmas. decorating the tree, the house, and making cookies with his mom. he enjoyed grilling with his dad and shopping with his brothers. anderson? >> adrienne broaddus, appreciate it. thank you. up next, there is new details about what president biden plans to say to russia's president putin when they speak one on one tomorrow and how putin may respond. ♪ ♪ ♪ "how bizarre" by omc ♪ no annual fee on any discover card. ♪ ♪ hi, i'm steve and i live in austin, texas. i work as a personal assistant to the owner of a large manufacturing firm. i've got anywhere from 10 to 50 projects going at any given time. i absolutely have to be sharp. let me tell ya, i was struggling with my memory. it was going downhill. my friend recommended that i try prevagen and over time, it made a very significant difference in my memory and in my cognitive ability. i started to feel a much better sense of well-being. prevagen. healthier brain. better life. look, serena williams... matrix... serena... matrix... serena... matrix... ♪ get your tv together with the best of live and on demand. introducing directv stream. ♪ ♪ ♪ hey google. ♪ ♪ ♪ ♪ ♪ ♪ - san francisco can have criminal justice reform and public safety. but district attorney chesa boudin is failing on both. - the safety of san francisco is dependent upon chesa being recalled as soon as possible. - i didn't support the newsom recall but this is different. - chesa takes a very radical perspective and approach to criminal justice reform, which is having a negative impact on communities of color. - i never in a million years thought that my son, let alone any six-year-old, would be gunned down in the streets of san francisco and not get any justice. - chesa's failure has resulted in increase in crime against asian americans. - the da's office is in complete turmoil at this point. - for chesa boudin to intervene in so many cases is both bad management and dangerous for the city of san francisco. - we are for criminal justice reform. chesa's not it. recall chesa boudin now. senior biden administration official tells cnn president biden will warn russia's president vladimir putin tomorrow during their scheduled video call that the u.s. is prepared to impose what he called, quote, substantive economic countermeasures meant to inflict quote significant and severe economic harm on the russian economy end quote. if russia takes military action against ukraine. meanwhile, vladimir putin is expected to tell president biden that nato must not admit ukraine as a member of nato. demand he is not likely to agree to. also tonight, the white house confirmed a full diplomatic boycott of the upcoming olympics in beijing, which means u.s. athletes can compete but no one from the administration will attend the winter games which start the first week of february. joining us now to talk about it all, fareed zakaria, host of fareed zakaria gps. so fareed, tomorrow in that video call between president biden and vladimir putin, how much do you think will be at stake? >> this is the highest-stakes diplomacy that joe biden has conducted since he's become president. there have been big events that have taken place. obviously, the collapse of kabul. the iran negotiations. but this one, biden is doing personally. and what is at stake here is that putin is testing how far he can go in intimidating ukraine and intimidating the west. biden has to try to push back in a way that is both firm but not so provocative that it precipitates the crisis that he is trying to avoid. it's a tough balance, and it's certainly as i say the high-stakes diplomacy that he has conducted personally as president. >> do you think he is really planning to invade ukraine? >> i think winston churchill had a great line about the russians in the '50s. he said they don't want war. what they want is -- are the fruits of war. what -- what putin wants is for ukraine to become much weaker, far more dependent on russia, and to never become a member of nato. so, i think this is all a series of intimidations directed at both ukraine to cripple it and at the west to say do not cross that line. do not make ukraine a member of nato. if you do, you know, i have got 175,000 troops on their border. how many do you have? >> so, it's interesting. i mean, as much as it is about ukraine, it is also about nato's power in -- in eastern europe. is that just because nato is a real sore spot for putin? i mean, the -- the idea of this alliance? >> absolutely. i remember one time when i met with him. um, he -- he had a litany of complaints about western policy. but they all centrally revolved around this idea that nato existed to defeat the soviet union during the cold war. we surrendered. the cold war is over. and yet, nato has kept expanding its borders eastward closer and closer to russia. why are you doing this? this is an existential threat to us. so, that is putin's world view. he is a -- a russian nationalist and he looks at ukraine becoming part of nato as kind of the final straw because this would bring nato right to russia's border. >> how -- i mean, what would be the process for ukraine becoming part of nato? i mean, is that really even on the table? >> well, you know, most people don't realize this but -- but nato has given ukraine a kind of a roadmap. they haven't said that ukraine will become a member but they have outlined a series of steps ukraine has to take in order to qualify. so, it -- in a sense, it's -- you know, ukraine is on a road to -- to present itself to nato for membership. no ultimate decision has been made. but that is what is worrying vladimir putin. >> so, is -- i mean, i guess u.s. levying new sanctions would be on the table and then, russia would perhaps retaliate against that? i mean, what -- what are the next steps on this? >> probably, the biggest weapon biden has is to threaten that he would cut russia off from the international financial system through a mechanism basically -- it's -- it's called swift. and, you know, if -- if the united states decides such as the power of the dollar that it will not allow you to bank in dollars, it becomes very hard for you to move money around. it becomes very hard for you to sell your oil and gas. >> i wanted to ask you about china. you did a documentary that aired last friday. what do you make of the white house' announcement today that there is going to be a diplomatic boycott by the u.s. of the upcoming-winter olympics in beijing? and does that really send any kind of a message at all? >> yeah, i think it does. i think that the administration is trying to balance the reality of china as a huge power, second largest economy in the world. the united states does enormous amount of trade with -- with china. the world does an enormous amount of trade. this is a very different power than russia. this is a huge player in the international economic space and, you know, great ancient civilization. with the very important objections the biden administration has, rightly, about chinese policy and xinjiang towards the uighurs. so, it's not a full boycott. you know, that -- that has tended to also not work very well. you punish your own athletes. so they have tried to do something where no government official will go to -- to kind of grace the occasion. to -- to witness the -- the olympics. but the athletes will be allowed to compromise -- to -- to compete. i think it's a reasonable line. it -- it demonstrates that this is not just words about xinjiang. that the united states is willing to back it with actions. but it's also not, you know, it recognizes that china is a major power in the world and we are going to have to live with it. >> fareed zakaria, appreciate it. thanks, fareed. >> pleasure as always, anderson. coming up in a minute. the former president pitting republican against republican in georgia to primary the governor who wouldn't help him overturn the race that he, himself, lost there. ♪ superpowers from a spider bite?

i mean, essentially, david perdue should be governor because brian kemp wouldn't interfere with the process? >> that's largely the argument they are going with. in fact, david perdue ironically today -- i actually laughed at the statement -- said that brian kemp was responsible for the loss of two senate seats in georgia. now, of course, david perdue was one of the senators who lost. probably more blame with him. i will tell you i was talking to a state legislator right before air time who told me that he and other members of the state legislature are getting phone calls from trump supporters saying if they don't come out endorse perdue, they can expect primary challenges in these newly redistricting lines. a lot of pressure coming to bear on republicans across the state. a lot of them think maybe it's time to stand up and just not do this. >> hmm. van, i guess some democrats might be relishing the idea of kind of a divisive republican gubernatorial primary in georgia but it seems to me they shouldn't because we need two functioning parties that are law-abiding and fact-based in this country. we need a healthy republican party. >> i -- i agree and -- and what saved constitutional democracy, the rule of law were two groups that don't agree on anything. one, you had a bunch of black women mostly who led the charge who -- who did unbelievable voter turnout. um, on the one hand. and then, you had conservative white men who were election officials -- mostly in the republican party -- who upheld the vote. those two forces. those liberal black women and those conservative white men are why we have continued functioning democracy in -- in this country. and yet, you see now a move to say let's repress the black vote and replace those honest conservatives with kind of pro-trump at all cost conservatives. this is a threat that we are facing now to the rule of law in this country. if you are a governor, and you are going to be replaced because you upheld the rule of law and the u.s. constitution, that is no longer a partisan issue, that's an american issue. i never thought i would be trying to defend somebody like kemp who i disagree with on everything. but a governor shouldn't be replaced and primaried for upholding the rule of law. >> well, erick, it's also -- i mean, i remember the days when then-president trump liked brian kemp. i mean, he used to say great things about him. about his -- you know, he liked the way he was handling covid. he -- you know, he couldn't say enough good stuff about him. >> yeah. and you know, that's one of the ironies here. one of the few times donald trump ever attacked brine kemp brian kemp prior to this was he thought he opened the state too soon last year, end of april i think it was when kemp opened the state. otherwise, he endorsed kemp last go-around and has now been working people for him largely because donald trump is very transactional. he wanted brian kemp to do something. ironically, though, and just to clarify this whole conversation which makes it more ridiculous is the georgia constitution actually prohibits the governor of the state of georgia from doing anything at all in an election. so they are going after kemp for not doing something in the election and the georgia constitution strictly prohibits him from doing anything whatsoever. >> but, erick, do you worry about this sustained effort by the former president? because it seems like now, there is going to be in a lot of states, folks who believe the big lie running for school boards -- not school board -- running for election boards to -- to, you know, be ones who are in a position of certifying the next elections. >> look. i -- i get hate mail on my radio show nearly every day when i tell people the election wasn't stolen. certainly, there were irregularities. i was an elections lawyer. there always are. but it wasn't stolen. and yeah, it does trouble me that the adamantsy of the people who believe this, but also i don't think they are the majority and i think to some degree, when you see president trump's polling within the republican party after january 6th, it was 90%, then 80, then 70. now, it's at 60%. time heals all these wounds and pretty soon republicans will be flirting with someone else. >> van, do you think that's true? >> well, you know, hope springs eternal. i -- we haven't seen -- we haven't seen evidence of that, yet. in other words, still the dominant force in the republican party remains donald trump. so far, there's nobody that's been able to emerge as a real contender and this is going to, in some ways, be the war to settle the score. this primary. do you have republican voters in georgia who believe in the rule of law more than they love donald trump? or not? because there's no reason to replace the sitting governor. he's as right wing as you can be. it's hard to find a more right-wing governor in the country than kemp. so, you can't be mad at him for anything if you are a republican voter than anything except that he didn't break the law help donald trump. >> and, van, how important is this race for stacey abrams? she's got a national profile now. she is going to be running for the governor there. there are no other primary challengers. >> well, listen. i mean, this is her moment. um, she -- look, she has gotten where she is through the dint of hard work. when the idea that you would have an african-american woman knocking on the door of being a governor in that state would have been preposterous ten years ago. even five year ago. she made it within a hair's breadth of winning last time and it's her turn and you are going to see a tremendous amount of support behind her and it's deserved. and then, what you are going to see is, though, on the republican side, is -- is she going up against kemp again? is it a rematch? or is she going up against a republican party that is more committed to donald trump than the rule of law? >> well, van jones, erick erickson -- oh, go ahead real quick, erick. >> real quick, that she is -- her announcement last week prompted david perdue to do this. so she is lining the chess pieces up on the board the way she wants and david perdue took her bait. >> hmm, interesting. eric, thank you so much. van jones, as well. appreciate it. a humanitarian crisis plaguing the already unstable nation of south sudan as historic floods threaten hundreds of thousands of people. cnn's clarissa ward is on the scene next. who invented car vending machines and buying a car 100% online. now we've created a brand-new way for you to sell your car. whether it's a year old or a few years old. we wanna buy your car. so go to carvana and enter your license plate answer a few questions. and our techno wizardry calculates your car's value and gives you a real offer in seconds. when you're ready, we'll come to you, pay you on the spot and pick up your car, that's it. so ditch the old way of selling your car, and say hello to the new way at carvana. ♪ ♪ ♪ (sha bop sha bop) ♪ ♪ are the stars out tonight?

have your homes been destroyed? they survived years of vicious civil war here. but these floods may pose the greatest threat, yet. they tell us their crops have been completely destroyed. so, what are you living on right now? what are you surviving on? the lilies? >> yeah. >> the lilies. the water lilies. are people getting sick from the dirty water? many people have waterborne diseases, they explain. the wells were all covered so we have to drink this water. while south sudan is no stranger to seasonal flooding, unity state hasn't been hit like this since the early 1960s. scientists say the floods have become much more intense and unpredictable in recent years, in part because of global warming. james? >> yes. >> hi, james. >> reporter: james loin is one of hundreds of thousands who have been displaced. he agrees to show us what's left of his family home. oh, my god. >> yeah. >> reporter: that's your motorcycle. >> yes. >> reporter: nothing is left except for his children's drawings on the walls. since the conflict erupted, we've never had a rest, he tells us. we've been constantly running, displaced, our children have had no relief from the dangers. now, he is forced to flee, once again. the journey to the promise of dry land is long and arduous. the lucky ones travel by boat. most swim or wade, going slowly but purposely through the muddy waters. some wpush makeshift floats, piled high. we come across a group of women, whose raft is stuck in the mud. the men of the family have gone to try to save their livestock. they left their destroyed home four days ago. have you been pushing this raft for four days? yes, they tell us. and along the way, they say, their food ran out. how old is your baby? >> 5 to 6 months. >> 5 to 6 months? are you worried about your children? yes, i'm worried, she says. that's why we keep moving. we still have several miles to push before we reach this narrow strip of dry land. according to unicef some 6,000 people have now settled here. dependent on aid to survive. >> we don't have enough food for them. >> they don't have bathrooms? and there are more people arriving every day? >> they continue to come min. >> reporter: you're doing everything you can. is it enough? >> that's why we are calling for a broader community. to make sure that children get schools and health care. >> reporter: as the stagnant waters continue to rise, so do diseases, like diarrhea and hepatitis e. concentration in children is at its highest level since 2013. those that find it to the venue, find little sanctuary. some of the main roads are now waterways. just a mile further, the ghostly remains of what was once a commercial hub. this used to be the central shopping area in town. as you can see, completely aa aextraordinarying. here, the effects of climate change aren't a hypothetical problem in the future. but a disaster in the presence. minister lamb concedes local authorities were completely unprepared and how are now unable to scope with the scale of the crisis. how much longer ask you cope with the situation as it stands? we don't know. >> reporter: they don't have long. next rains are expected in may. and if the current waters don't recede, the peer is this area will be wiped off the map. like serena was built to hold back to emmarching waters. breeches are common, leaving man to take the situation for their own faults. as the waters continue to rise. >> i mean, is this expected to be the new norm in this region? >> well, this has everybody so worried. if this is the new normal, i can tell you what we have been able to see. south korea does not have the infrastructure to needed to deal with a top hat crisis. you have a compound effect. every time it hits, the situation gets worse and worse. what we know from the u.n. is that africa is disprop dispropodisprop disproportionately affected by climate change. it's important for our vurers to remember. south susan, 125 miles on the outside of this road. and yet, they are paying a very heavy toll for continued global warming. >> i'm so glad you're there. thank you. california republican congressman devin nunes will be leaving kohn.
