because of a contentious exchange in saturday's debate. >> let's stop once and for all with this fiction that barack obama doesn't know that he's doing. >> there it is, the 25 second memorized speech. >> barack obama is wanting to -- trying to change america. >> some of the sparring from saturday's debate between donald trump and jeb bush continued on the campaign trail sunday, trump mocking jeb bush's mother, former first laid barbara bush for joining the campaign. >> poor poor poor jeb bush who brings out his mother because he needed help. no, he needed help, mommy, please come, walk in the snow, mom. >> trump and yep also sparred saturday night over the issue of eminent domain. >> democratic can't hillary clinton is back campaigninging new hampshire. she spent part of the weekend in flint michigan where she offered support as that city deals with its water crisis. >> i'm here because for nearly two years, mothers and fathers

were voicing con veterans about the water's color, about the smell, about the rashes that it gave to those who were bathing in it. >> bill clinton unleashed an attack on bernie sanders, saying his campaign had been sexist and dishonest. sanders denied the accusations. >> we will do everything we can and i think we have tried. >> with one day to go, the latest university poll has bernie sanders leading by 10% with a margin of error of 4.4 percentage points down from a 14-point bernie lead last month. al jazeera's libby casey is live in the thick of things in manchester, new hampshire, good morning. today is the last full day for can't dates to really try to sway undecided voters.

we understand there is a lot of them there. at this point, what do the candidates have to do? >> that's right. stephanie. they have to seal the deal. it's voters who are undeclared, not just undecided. a lot of people around registered at republicans or democrats. they may go where the enthusiasm lice. candidates want to get them motivated, keep them excited and bring them out to the polls tomorrow. we are seeing the candidates crisscross the state. snow is expected today. that play slow campaign momentum, but people in new hampshire are used to snow, so it shouldn't stop things entirely. >> i can't imagine it will. it's been such a contentious race especially in the gop, second place is up for grabs among the republican candidates now. did everything change after the weekend debate? >> we may not know until the votes tallied tomorrow. marco rubio yo really did come under attack from the guns, namely chris christie, jeb bush

and john kasich and chris christie was the most successful lobbying assaults at marco rubio. whether that will translate to votes remains to be seen. it may shrink enthusiasm over marco rubio and what chris christie was saying was this senator who has miss add lot of votes in congress doesn't have the experience to be president of the united states. the goes in this race need to make a strong showing tomorrow or for some of them, this may be the end of the trail. john kasich spent many weeks and months here in new hampshire, as have bush and christie trying to connect with voters on that individual personal level, holding the town halls, holding the coffee events, going to the diners. now donald trump hasn't done nearly as much of that, but his name is still one that everyone's talking about, second tear, though, still very important to watch. >> is there a candidate who can

benefit the most from all the undecided voters? >> bernie sanders may end up getting some of this enthusiasm, but you may see some of these republicans who haven't been talked about as much in the national media pulling in voters. it depends if they go with personal connections, hearing the personal narratives of jeb bush and chris christie or if they're drawn to the he enthusiasm of donald trump. he has not been able to keep the momentum of the enthusiasm up and skipping out on the iowa debate recently may have hurt him a little bit. he was here over the weekend. he is doing his events. he's taking a little more of a traditional campaign route. making an appeal to voters in a way that is a little more down to earth than when he was doing prior to this. it remains to be seen.

regions. >> we cannot and will not allow this to happen. >> the rocket launch violated four different u.n. security council resolutions. it is not clear if china will agree to new stiffer sanctions. >> mitt security researcher jim walsh said the u.s. needs to change the way it deals with china if it wants support handling the north. >> we are doing the same old same old, publicly hectoring china saying why aren't you doing more. that's not a very smart way to go about it. we are more likely to be effective with china in quiet talks behind the scenes. every time we shout at china, it reduces their freedom of movement. china's dealing with an ally, an ally though don't like, that be causes them problems, but an ally nonetheless. the more we scream it, china do more, if the chinese do what we want, it will look to the north koreaens like their supposed

friend is in cahoots with the enemy. we need to be more subtle, indirect and that will be more effective. >> china's foreign minister said it has called on all sides to show restraint. it condemns the u.s. and south korea's what it calls aggression against north korea. >> while north korea insists the launch was to put a satellite in orbit, the concern is the technology could someday launch a nuclear weapon. >> north korea's rocket, similar if not identical to the one that put a satellite into space on sunday. it has never been tested as a bliss system missile but experts say could be adapted to carry a payload up to 10,000 kilometers, putting asia, europe and the u.s. within range. the trouble is it is not consider add very good bliss system missile. it can only be launched from fix

would sites and takes hours to prepare its volatile fuel for launch, so it's hardly a responsive weapon. north koread also need to develop a nuclear warhead small enough and light enough to fit into the rocket. so far, there's no evidence of this. even if north korea could get a bomb into the upper atmosphere above a target, it has another challenge. it would need to bring it back down in a controlled way to stop it burning up as it reaches speeds of 25,000 kilometers an hour. again, there's no evidence it has the capacity to do this. experts say a successful launch could help north korea develop this, the intercontinental ballistic missile. the rockets are different and work in very different ways. all of which means it is probably away space launch vehicle which in its current form has little potential as a

ballistic missile. >> he also says north korea it at away advantage since it shares a border with the world's largest economy, china, making it easier to get around international sanctions. the italian president is expected to talk to president obama about a number of issues, including isil and the refugee situation in europe. escalated to meet with vice president joe biden and secretary of state john kerry. the iraqi military said it is making gains against isil in anbar province. civil yearns were evacuated. they retook the area over the weekend. iraqi officials say victory allowed them to close in on fallujah and cut off crucial isil ply routes from syria. it is a somber new years in taiwan. people are still trapped under

>> i pray for those people still trapped and their safety. >> i pray to god that hopefully there will be more survivors. >> rescuers are now wrestling with the difficult decision of whether to bring in heavy lifting gear to move some of the upper parts of this structure to get to people who may be buried lower down in the rubble. they've resisted doing so so far, because of course it may cause a further collapse, losing the very people they are trying to save. we are coming to a critical point now. we're into day three of the rescue operation. the calculation is people can't survive longer than three days without food and water. people buried deep in the rubble deserve a chance to be freed. 35 of the 38 people confirmed dead were killed in that one collapsed apartment building. president obama pressures congress to provide funds to study zika. the new calls to bring back a banned toxic test side to fight

its name is d.d.t. >> this 1945 propaganda film produced by the u.s. war department hailed the benefits of d.d.t. during world war ii. >> yes, today, d.d.t. is necessarily a military weapon. we're turning it out by the thousands of tons. >> it had been around since the 1870's. in 1939, it was recognized as a stunningly effective pesticide. the army used it to fight malaria, typhus and other insect borne diseases around the world. it is a neurotoxin that causes violent convulsions that paralyze and kill insects. >> the homecoming of the healthiest army in military history will be in no small part due to d.d.t., our great new weapon for war today and peace tomorrow. >> after the war, d.d.t. gained widespread civilian and industrial use. millions of tons were sprayed in farms, gardens, forests and homes.

making it unfit for all life? >> throughout the 1960s, environmentalists pushed for tougher regulation of d.d.t. joni mitchell's big yellow taxi helped to make the issue part of our international culture. >> hey farmer farmer, put away the d.d.t. now. >> the e.p.a. banned widespread use of d.d.t. in the united states, but over the next two decades, the u.s. continued to export hundreds of tons of d.d.t. to the developing world. john terrett, al jazeera. the former owner of a company involved in a big chemical spill in west virginia will be sentenced today. the spill two years ago tainted the water supply for 300,000 people. former freedom industries owner faces one year in prison. he is one of six men who pleaded guilty for the spill.
