all: cbs cares! two weeks to go until the first votes are cast in the 2016 race for president. a new poll has hillary clinton 25 points ahead of bernie sanders in the democratic race. martin o'mally a distant third. the democrats held their fourth debate last night in charleston. here is some of what they said. >> right before the debate you changed your position on immunity from lawsuits for gun manufacturers. can you tell us why? >> well, i think secretary clinton knows what she says is very disingenuous. i have a d-minus voting record from the nra. i was -- in 1988, there were three candidates running for congress in the state of vermont. i stood up to the gun lobby and came out and maintained the position that in this country, we should not be selling

military-style assault weapons. and i think it should be a federal crime if people act as strawmen. we have seen in this city a horrendous tragedy. of a crazed person praying with people, then coming out and shooting nine people. this should not be a political issue. what we should be doing is working together. and by the way, as a senator from a rural state that has virtually no gun control, i believe that i am in an excellent position to bring people together to fight for gun legislation -- >> you didn't answer the question that you did change your position on immunity for gun manufacturers so can you answer the question -- >> what i have said is that the gun manufacturers liability bill had some good provisions. among other things we prohibited ammunition that would have killed cops who had protection on. we had child safety protection

on guns in that legislation. and what we also said is that a small mom and pop gun shop who sells a gun legally to somebody should not be held liable if somebody does something terrible with that gun. so what i said is i would relook at it. we are going to relook at it. and i will support stronger provisions. >> secretary clinton, would you like to respond to senator sanders? >> yes. look, i have made it clear based on senator sanders' own record that he has voted with the nra, with the gun lobby, numerous times. he voted against the brady bill five times. he voted for what we call the charleston loophole. he voted for immunity from gunmakers and sellers which the nra said was the most important piece of gun legislation in 20 years. he voted to let guns go onto amtrak, guns go into national parks. he voted against doing research to figure out how we can save lives. let's not forget what this is

about. 90 people a day die from gun violence in our country. that's 33,000 people a year. one of the most horrific examples not a block from here, where we had nine people murdered. now, i am pleased to hear that senator sanders has reversed his position on immunity and i look forward to him joining with those members of congress who have already introduced legislation. there is no other industry in america that was given the total pass that the gunmakers and dealers were and that needs to be reversed. at least two people were killed by tornados overnight in central florida. the couple was killed in manatee county when their mobile home was hit. another tornado in the beach town of siesta key caused widespread destruction leaving 17,000 without power. the search continues for 12

tonight we're learning more about the victims and survivors of a terror attack in west africa. at least 28 people were killed on friday when gunmen opened fire at a hotel and cafe in the nation of burkina faso. here's jonathan vigliotti. >> reporter: as security forces surrounded the splendid hotel and neighboring cappuccino cafe, both under siege by terrorists, amy riddering tried desperately to reach her husband mike. he was at the cafe when the assault began friday night. i still have no news about mike, she wrote on her facebook page saturday morning, as military forces were still trying to regain control.

florida native mike riddering moved with amy and their two daughters to burkina faso in 2011 to start an orphanage. mike and a pastor were at the cafe in the country's capital walking ouagadougou to meet new volunteers. the pastor called amy after escaping. gunmen came into the restaurant shooting and everyone ran to hide. the pastor somehow had mike's phone and called, wrote amy. it was still unclear if mike survived. another american, edward bunker, emerged from his room to a deserted hotel lobby. >> there was someone with a gun going down the street. and this was really the moment when i kind of realized that there was something majorly amiss. >> reporter: the 12-hour siege began when heavily armed al qaeda militants, two of them women, stormed the buildings and set off car bombs. in all, 28 people were killed, including a canadian family of four who were on a humanitarian trip.

11 americans, including edward bunker, made it out alive. mike riddering did not. you left quite a legacy here, i can only imagine the adventures you're having now, wrote amy's final post. jonathan vigliotti, cbs news, london. up next, candidates court the nation's fastest-growing voting bloc. less than ten months to election day, some presidential

>> reporter: shakir, a banker, points to the 2014 senate election in his state, virginia. >> thank you, virginia! >> reporter: where asian-american voters made the difference for democrat mark warner, who won by less than 1% of the vote. >> republicans used to enjoy the majority of asian-american support back in the 1990s. >> reporter: university of california professor kartha runs the nonpartisan asian-american survey which shows a political shift after the 1992 election when 31% of asian-americans voted for democrat bill clinton. by 2012, 73% voted for brady barack obama. >> what changed? >> one is the clintons. this is where hillary clinton can draw on a lot of support from what she and her husband did in the 1990s in terms of doing outreach to these populations. another part that's changed is the republican party's rhetoric on immigration has turned off a lot of voters. >> we are a country built by the hard work of generations of

immigrants. and we are stronger because of our diversity and our openness. >> reporter: something asian-americans like to hear, because nearly two-thirds of their population was born outside the u.s. carter evans, cbs news, san gabriel, california. still ahead, every presidential race should be as fun as this. david bowie's last album is now his first number one album in the u.s. one week after bowie's death "black star" debuted on top the billboard 200 today. the album was released two days

and beer.

we close tonight at a centuries-old monastery in italy where american monks are making heavenly harmonies as they tap into history. ♪ >> reporter: close your eyes and you could be back in the 11th century. that's when the chants were written and when st. augustine founded the benedictine order of monks in this basilica. ♪ father folsom, graduate of the indiana school of music, came here in 2000 with the simple aim of rejuvenating the monastery and bringing its music back to life. >> if monks come, candidates come and they don't sing or think they can't sing, we give them voice lessons because it's so much part of our life. if you can't sing you're going to be pretty bored here, i think. >> reporter: the voice lessons

are so good that a music company asked them to cut a cd. it ended up at the top of billboard's classical charts. the recording sessions had to be slotted into a daily schedule of work and prayers that start at 3:45 in the morning. the monk on the album cover, connecticut-born father benedict nivikof, figured it would have less than limited appeal. >> music and beer can get where words often can't. >> they're both good for the soul? >> good for the soul, especially the beer. >> reporter: it turns out that beer is another monastic specialty that has roots in medieval times. brother francis, the brewmaster from dallas, says ancient brewing was a kind of public health service because the boiling process sterilized often dirty water. >> it's really an act of creation, just like god. all things god may be glorified is one of the mottos in the benedictine order. >> reporter: the monks brew and sell a blond beer that's 6% alcohol and a dark version that's 10%.

>> we don't want it watery, we don't want it light. it's something that grabs your attention. >> reporter: it certainly does that. if you thought the music was divi divine, you should try the beer, trust me. and given the quality of the music, that's saying something. the legacy of st. augustine and his monks, two wonderful ways to soothe the soul. >> cheers. >> that is the overnight news for this sunday. for some of you the news continues. for others check back with us a little later for the morning news and "cbs this morning." from the broadcast center in new york city, i'm jeff glor.

this is the "cbs overnight news." welcome to the overnight news. i'm jeff glor. the democratic presidential candidates gathered in charleston, south carolina, for their fourth and final debate before the iowa caucuses. here's some of what the candidates had to say. >> right before the debate you changed your position on immunity from lawsuits for gun manufacturers. can you tell us why? >> well, i think secretary clinton knows that what she says is very disingenuous. i have a d-minus voting record from the nra. i was in 1988, there were three candidates running for congress in the state of vermont. i stood up to the gun lobby and came out and maintained the position that in this country, we should not be selling military-style assault weapons. and i think it should be a

federal crime if people act as strawmen. we have seen in this city a horrendous tragedy. of a crazed person praying with people, then coming out and shooting nine people. this should not be a political issue. what we should be doing is working together. and by the way, as a senator from a rural state that has virtually no gun control, i believe that i am in an excellent position to bring people together to fight for gun legislation -- >> you didn't answer the question that you did change your position on immunity for gun manufacturers so can you answer the question -- >> what i have said is that the gun manufacturers liability bill had some good provisions. among other things we prohibited ammunition that would have killed cops who had protection on. we had child safety protection on guns in that legislation. and what we also said is that a

small mom and pop gun shop who sells a gun legally to somebody should not be held liabe if somebody does something terrible with that gun. so what i said is i would relook at it. we are going to relook at it. and i will support stronger provisions. >> secretary clinton, would you like to respond to senator sanders? >> yes. look, i have made it clear based on senator sanders' own record that he has voted with the nra, with the gun lobby, numerous times. he voted against the brady bill five times. he voted for what we call the charleston loophole. he voted for immunity from gunmakers and sellers which the nra said was the most important piece of gun legislation in 20 years. he voted to let guns go onto amtrak, guns go into national parks. he voted against doing research to figure out how we can save lives. let's not forget what this is about.

90 people a day die from gun violence in our country. that's 33,000 people a year. one of the most horrific examples not a block from here, where we had nine people murdered. now, i am pleased to hear that senator sanders has reversed his position on immunity and i look forward to him joining with those members of congress who have already introduced legislation. there is no other industry in america that was given the total pass that the gunmakers and dealers were -- >> and that's the -- >> -- and that needs to be reversed. >> secretary clinton, is it really fair to say that bernie sanders wants to kill obamacare? >> well, andrea, i am absolutely committed to universal health care. i've worked on this for a long time. people may remember that i took on the health insurance industry back in the '90s. and i didn't quit until we got

the children's health insurance program that insures 8 million kids. and i certainly respect senator sanders' intentions. but when you're talking about health care the details really matter, and therefore we have been raising questions about the nine bills that he introduced over 20 years as to how they would work and what would be the impact on people's health care. he didn't like that. his campaign didn't like it either. and tonight he's come out with a new health care plan. and again, we need to get into the details. but here's what i believe. the democratic party and the united states worked since harry truman to get the affordable care act passed. we finally have a path to universal health care. we've accomplished so much already. i do not want to see the republicans repeal it, and i don't want to see us start over again with a contentious debate. i want us to defend and build on the affordable care act and improve it.

>> senator sanders? >> secretary, secretary clinton didn't answer your question. because what her campaign was saying, bernie sanders who has fought for universal health care for my entire life, he wants to end medicare, end medicaid, end the children's health insurance program. that is nonsense. what a medicare for all program does is finally provide in this country health care for every man, woman and child as a right. now the truth is that franklin delano roosevelt, harry truman, you know what they believed in? they believed that health care should be available to all of our people. i'm on the committee that wrote the affordable care act. i made the affordable care act along with jim clyburn a better piece of legislation. i voted for it. but right now what we have to deal with is the fact that 29 million people still have no

health insurance. we are paying the highest prices in the world for prescription drugs. getting ripped off. and here's the important point. we are spending far more per person on health care than the people of any other country. my proposal, provide health care to all people, get private insurance out of health insurance, lower the cost of health care for middle class families by 5,000 bucks. that's the vision we need to take. >> you know, i have to say i'm not sure whether we're talking about the plan you just introduced tonight or we're talking about the plan you introduced nine times in the congress. but the fact is, we have the affordable care act. that is one of the greatest accomplishments of president obama, of the democratic party, and of our country. and we have already seen 19 million americans get insurance. we have seen the end of pre-existing conditions keeping

people from getting insurance. we have seen women no longer paying more for our insurance than men. and we have seen young people up to the age of 26 being able to stay on their parents' policy. >> i'm not -- >> there are things we can do to improve it, but to tear it up and start over again, pushing our country back into that kind of a contentious debate i think is the wrong direction. >> it is absolutely -- >> i have to talk about something that's actually working in our state -- >> governor -- >> no one's saying tearing this up, we're going to go forward. but what the secretary neglected to mention, not just the 29 million still have no health insurance, that even more are underinsured with huge co-payments and deductibles. tell me why we are spending almost three times more than the british, who guarantee health care to all of their people. 50% more than the french. more than the canadians. the vision from fdr and harry truman was health care for all people as a right in a cost-effective way.

we're not going to tear up the affordable care act.

americans released as part of a prisoner swap with iran are one step closer to home. it's been a year of rapid developments between the u.s. and iran. iran is now allowed to sell oil on the open market after sanctions were lifted. it will have access to the global banking system and will gain access to more than $100 billion in frozen assets in banks around the world. president obama called it a victory for smart diplomacy. >> this is a good day. because once again we're seeing what's possible with strong american diplomacy. as i said in my state of the union address, ensuring the security of the united states and the safety of our people demands a smart, patient, and disciplined approach to the world. that includes our diplomacy with the islamic republic of iran.

for decades our differences with iran meant that our governments almost never spoke to each other. ultimately that did not advance america's interests. over the years iran moved closer and closer to having the ability to build a nuclear weapon. but from presidents franklin roosevelt to john f. kennedy to ronald reagan, the united states has never been afraid to pursue diplomacy with our adversaries. as president i decided that a strong, confident america could advance our national security by engaging directly with the iranian government. we've seen the results. under the nuclear deal that we, our allies and partners reached with iran last year, iran will not get a chance on a nuclear bomb. the region, the united states and the world will be more secure. as i've said many times, the nuclear deal was never intended to resolve all of our

differences with iran, but still, engaging directly with the iranian government on a sustained basis for the first time in decades has created a unique opportunity, a window to try to resolve important issues. and today i can report progress on a number of fronts. first, yesterday marked a milestone in preventing iran from obtaining a nuclear weapon. iran has now fulfilled key commitments under the nuclear deal. i want to take a moment to explain why this is so important. over more than a decade iran had moved ahead with its nuclear program and before the deal it had installed nearly 20,000 centrifuges that could enrich uranium for a nuclear bomb. today iran has removed two-thirds of those machines. before the deal, iran was steadily increasing its stockpile of enriched uranium. enough for up to ten nuclear bombs. today, more than 98% of that stockpile has been shipped out of iran, meaning iran now doesn't have enough material for even one bomb.

before, iran was nearing completion of a new reactor capable of producing plutonium for a bomb. today the core of that reactor has been pulled out and filled with concrete so it cannot be used again. before the deal, the world had relatively little visibility into iran's nuclear program. today, international inspectors are on the ground and iran is being subjected to the most comprehensive, intrusive inspection regime ever negotiated to monitor a nuclear program. inspectors will monitor iran's key nuclear facilities 24 hours a day, 365 days a year. for decades to come, inspectors will have access to iran's entire nuclear supply chain. in other words, if iran tries to cheat and they try to build a bomb covertly, we will catch them. so the bottom line is this. whereas iran was steadily expanding its nuclear program, we have now cut off every single

path that iran could have used to build a bomb. whereas it would have taken iran two to three months to break out with enough material to rush to a bomb, we've now extended that breakout time to a year. and with the world's unprecedented inspections and access to iran's program, we'll know if iran ever tries to break out. now that iran's actions have been verified, it can begin to receive relief from certain nuclear sanctions and gain access to its own money that had been frozen. and perhaps most important of all, we've achieved this historic progress through diplomacy. without resorting to another war in the middle east. i want to also point out that by working with iran on this nuclear deal, we were better able to address other issues. when our sailors in the persian gulf accidentally strayed into iranian waters, that could have sparked a major international

incident. some folks here in washington rushed to declare that it was the start of another hostage crisis. instead we worked directly with the iranian government and secured the release of our sailors in less than 24 hours. this brings me to a second major development. several americans unjustly detained by iran are finally coming home. in some cases these americans faced years of continued detention. and i've met with some of their families. i've seen teir anguish. how they ache for their sons and husbands. i gave these families my word. i made a vow that we would do everything in our power to win the release of their loved ones and we have been tireless. on the sidelines of the nuclear negotiations our diplomats at the highest level, including secretary kerry, used every meeting to push iran to release our americans. i did so myself in my conversation with president rouhani. after the nuclear deal was

completed, the discussions between our governments accelerated. yesterday these families finally got the news they had been waiting for. in a reciprocal humanitarian gesture, six iranian americans and one iranian serving sentences or awaiting trial in the united states are granted clemency. these individuals were not charged with terrorism or violent offenses. they're civilians and their release is a one-time gesture to iran given the unique opportunity offered by this moment and the larger circumstances at play. and it reflects our willingness to engage with iran to advance our mutual interests even as we ensure the national security of the united states. so nuclear deal, implemented. american families, reunited. the third piece of this work that we got done this weekend involved the united states and iran resolving a financial dispute that dated back more

than three decades. of course, even as we implement the nuclear deal and welcome our americans home, we recognize that there remain profound differences between the united states and iran. we remain steadfast in opposing iran's destabilizing behavior elsewhere, including its threats against israel and our gulf partners and its support for violent proxies in places like syria and yemen. we still have sanctions on iran for its violations of human rights, for its support of terrorism, and for its ballistic missile program. and we will continue to enforce these sanctions vigorously. iran's recent missile test, for example, was a violation of its international obligations. and as a result, the united states is imposing sanctions on individuals and companies working to advance iran's ballistic missile program. and we are going to remain vigilant about it. we're not going to waver in defense of our security or that

of our allies and partners. but i do want to once again speak directly to the iranian people. yours is a great civilization with a vibrant culture that has so much to contribute to the world. in commerce, in science, in arts. for decades your government's threats and actions to destabilize your region have isolated iran from much of the world. and now our governments are talking with one another. following the nuclear deal, you, especially young iranians, have the opportunity to begin building new ties with the world. we have a rare chance to pursue a new path, a different, better future that delivers progress for both our peoples and the wider world. that's the opportunity before the iranian people. we need to take advantage of that. so my fellow americans, today we're united in welcoming home sons and husbands and brothers who in lonely prison cells have

endured an absolute nightmare. but they never gave in and they never gave up. at long last they can stand tall and breathe deep the fresh air of freedom. as a nation, we face real challenges. around the world and here at home. many of them will not be resolved quickly or easily. but today's progress, americans coming home, an iran that has rolled back its nuclear program and accepted unprecedented monitoring of that program, these things are a reminder of what we can achieve when we lead with strength and with wisdom. thank you so much. god bless you, god bless the united states of america.
