yemen intensify in an effort to keep the conflict spilling over the border into saudi arabia. iraq's ambassador to the u.s. discusses an upcoming visit to washington d.c., and the fight against i.s.i.l. well she's been secretary of state a u.s. senator and, of course she's been the first lady. hillary clinton still has her eyes on a higher office. today in a video posted online she announced she's making a run for the white house. >> i'm getting ready to do something too. i'm running for president. americans fought their way back from tough economic times, but the deck is stacked in favour of

those at the top. every day americans need a champion, and i want to be that champion libby casey is live in washington d.c. for us tonight. good evening. a lot of people were waiting for this announce: why did mrs. clinton -- announcement. why did mrs. clinton choose this moment. >> the campaign hoped to hit the sweet spot not launch so early that they'd fizzle out, but get in the race to build momentum leading up to the 2015 race. there was frustration from the hillary clinton supporters they wanted her to commit. the wait is over. the announcement was not featuring throngs of people can'ting her name they went -- chanting her name. they went with an understated approach. they want is to be about helping people not about clinton.

>> reporter: a presidential roll out not on a stage but online through video. with that hillary clinton jumped into the presidential race after a bruising defeat to now president obama. the video's tone is one of optimism rather than the candidate herself. every day we are trying to get more and more ready and prepared. a big boy coming your way. tapping into optimism. i'm hitting the road to earn your vote. because it's your time and i hope you'll join me on the journey. >> the announcement was months in the making. hillary clinton talked about her plans, with the pact raising more than 15 million, and laying ground work in key states where the 2008 primary bid rode off the rails and she came in in a

disappointing third place. it plans to combine old-fashioned events with modern social media, as hillary clinton did today, using twitter to spread the word - in english and spanish. the much anticipated announcement drew fire from republicans eager to capitalize on attention and do fundraising of their own. >> hillary clinton represents the worse of the washington machine there is no doubt the race for 2016 is on. >> the campaign hopes to set a different tone to 2008 when hillary clinton was accused of taking status and voters for granted. she is staying out of the spotlight instead of doing a by event. she's working the phones

connecting with the campaign supporters. watch her hitting the trail. she'll be in iowa a key part of strategy. the campaign says next month they'll do a launch. by then they'll have set the tone and gain momentum. >> libby casey live for us from washington d c. let's bring in michael sure joining us from los angeles. good evening. welcome to you. what does the way clinton chose to announce say about her campaign? >> well it shows that there's a different kind of outreach that hilary's campaign will do. i spoke to someone saying that it wept as well as it -- went as well as they could hope. it gets younger people talking. it will be difficult than in 2000. >> does her bean on opponent help or hurt her now?

there are two schools of thought of the there's enough that she has to look at what she did wrong last time and what she has been doing wrong in terms of communicating with middle class americans, that she can correct that now, and i said it before by voting running against old hillary, the hillary of 2008. she has to beat that hillary, and with the launch they seem to say that they are pleased with the way it's gone. >> as we head into 2016 does it matter that she is a woman and would be the first woman president of the united states. >> she'll play it a little differently. it matters, but what is good for hillary clinton is she does not have an opponent that would be a

barrier breaker. she had that as the first african american candidate and to run for office and make it that far. she's not going to have that this time. rather than talk about issues pertaining to women, if she portrays herself in a softer way, a mother and a grandmother. that will be part of what the challenge will be for hillary clinton, to say "i'm one of you" and her husband said "i feel your pain", she'll have to do a little of that. that will be an interesting thing to watch. >> knowing the amount of money clinton will raise, how does this impact other would-be democratic candidates do you think? >> you saw an email that went out from a group. i'd hate to work for him on a day like today, a lot the money it goes to joe biden, hillary

clinton will have that fundraising ability, and it will be difficult, almost impossible to match her in terms of fundraising. there'll be an niche candidate. it's not unprecedented, but it will be difficult to go up against the behome either like hillary clinton. marco rubio is expected to make an announcement tomorrow. is clinton overshadowing him. >> if i was marco rubio, i'd call to see if i can get my government back on the freedom tower. it's a little unfortunate for marco rubio, but it's a matter - you know he would have gotten headlines and notice. there'll be a lot written about him tomorrow. these are kind of motions - going through the motions that the candidates have to do. there are republicans that are going to be running, and matter as a republican more than now as

someone that faces off against hillary clinton. it's not a great day knowing that hillary clinton was going to announce on sunday. >> thank you, live for us in los angeles. >> cubans in havana and miami are expressing their views. president obama and raul castro had their first formal meeting in half a century. many are looking for an easing of restrictions. >> reporter: all kooub scrns expect the u.s. government will soften the embargo against america. we cubans have the right to breathe freely. >> not everyone is open an anti-government group, the ladies in white held a protest in havana saying little will change after the warming of relations. >> cubans in the u.s. hope the government-backed home will ease

>> instead of making dangerous concessions to iran now is the time for the international community to reassert and fortify demands for a better deal. we must not allow iran the sponsor of global terrorism, to have an easy path to nuclear weapons that will threaten the entire world. binyamin netanyahu says iran needs the deal more than any other nation and should be the one making concessions to get it done. >> insurgents in afghanistan have been gaining ground at the end of n.a.t.o.'s combat mission. a report details more civilians killed or injured. 136 civilians died. 385 wounded. that is an 8% increase. syrian monitors say a government air strike killed nine, happening in a rebel-controlled

of weapons. >> earlier, michael eaves spoke with the iraqi ambassador. here is what he had to say regarding the challenges the iraqi government is facing. >> as you may know the challenges ahead are numerous. we have high dependency on the oil prices. we hope that a recovery will help us in a positive way. we know that we are outreaching to i.m.f. world bank and are selling bonds and so on to make up to some of that deficit. war, by its own nature is not - it's a process which requires a certain amount of funds, and we seek support from our port ners in the united states and others

to make up for that and accelerate the liberation from our land and i.s.i.s. and d.a.e.s.h. he added that he hoped the obama administration will listen to a request for more assistance. >> in yemen battles are intense. iran called for sued saudi arabia to end air tricks. they have no intention of backing down. we have a report near the saudi-yemen boarder. >> saudi families mourning the death of loved ones. the body of one of three soldiers killed my houthi mortar shells on friday is about to be buried. the governor is here to convey condolences. among the objectives is to stop the conflict in yemen spilling into saudi arabia. now, there are fears the kingdom may be forced to order a ground invasion. yemen and saudi arabia vary a

1,800km border. control over this vast territory is never easy. refugees are heading north. the latest wave include somalis and ethiopians. they are not only running away from the conflict but from worsening life conditions in yemen. most of these people arrived on foot. as they crossed the border there was fresh fighting. >> i'm from sadr. i came seeking a job. there's no jobs in yemen, and the situation is miserable. only war and explosions. life there is difficult. we arrived to yemen by sea, and took the road across to tiaz until we entered saudi arabia. at first we are only 30. when we were captured the

middle man managed to escape. i paid him 500 for his service. >> there was no let up. with a daily average. the coalition says the strikes are breaking the houthis and causing them to lose the fight. we have targeted a number of days they have been converted into weapons and stores. they became command centers. we destroyed them. >> saudi arabia says it managed to muster the support of major forces in yemen. a mobilization has been announced among tribes to confront the houthis and forces loyal to the former president. many believe that without a unified command, those may not be able to tip the scale in favour of the anti-houthi campaign

significant number of people haven't bothered registering. >> he's portraying himself as a clown. >> miriam is an opposition leader in a bloc of parties, including liberals, secularists and communists. >> we want a peaceful, united sovereign sudan, with equal citizenship, and transitional justice. so - and the toppling of the regime. it is a prerequisite. >> sudan's opposition is splintered. last august liberals and secularists formed an historic alliance with the party representing rebels fighting in darfur and the south, worrying other opposition block including government officials and islamist groups - they feel sidelined.

>> it's defeating for opposition parties to demand the exclusion of certain political elements. it runs against the grain of democracy itself. >> reporter: having deemed the elections irrelevant opposition is focussing on their own campaigns, trying to end the conflict in the south and west, and enlisting the support of the international community. what is unresolved is if they'll recognise the new government federal police in mexico detained a top drug trafficker. he has been wanted for running shipments of cocaine from central america to the united states. he has ties with other known suspected drug traffickers tens of thousands of people across brazil took to the streets calling for the president to step down.

welcome back here is the top stories, hillary clinton ended speck oulation and -- speculation and announced that she is running for president in 2016. the former secretary of state, senator from new york and first lady made the announcement by way of an online video hold your fire that is what secretary of state john kerry's message is to critics of the nuclear deal reached with iran. the secretary of state wants congress to hold on until the

deadline saudi arabia hits for mour cities with air strikes -- four more cities with air strikes. houthi fires have been firing across the northern border into saudi arabia. 30 tonnes of medical aid arrived in the capital city of sanaa it's sunday night, time for our look at "the week ahead". tomorrow the senate returns from a 2-week recess and will have a day and a half to take up a bill that overhauls how medicare payments are made. the measures sailed through the house in march by a vote of 392-37. if the senate does not pass its version, doctors that treat medicare could see fees cut by 21%. >> don't look now, we are governing. >> reporter: in a show of bipartisanship the house approved the medicare act, the dock fix bill as it's known.

it scrapped what many agree is a flawed way for medicare doctors to get paid. the balance budget act mandated positions be compensated through a formula known as the sustainable growth rate. >> the idea was to keep increases and medicare reimbursements from exceeding gross domestic product. cons yeses voted and spent -- congress voted and spent $150 million to improve a doc fix. >> we have patched the problem 17 times over the last 11 years. i decided i had enough of it. >> the house sent a bill to repeal the sgr transitioning medicare away from a fee for care. >> we will transition medicare

away from volume-based to one that rewards value, ensures payments and improves the quality of care. with this we give american seniors confidence. >> doctors receive rewards and penalties, compared with position-developed thresholds. while there's little argument that the counter payment system needed changes, some are concerned that this may not be the best way to do it. >> the measure passed by the house would cost $214 billion. and add $141 billion to the deficit. >> nancy pelosi agreed to let aflupt seniors put the ball. starting next year: those making between 160 and

214,000 would have to pay 80%, rather than 65%. however, a programme to help lower income care beneficiaries would be extended. chip the insurance health programme would see funding extended for two years, and more than 7 billion would be ear-marked for community health centers. president obama indicated that he would siped bill if it makes it through the -- sign the bill if it makes it through the senate. senator leader mitch mcconnell seemed encouraged. >> i want to reassure everyone interested in the legislation that we'll move to it. >> reporter: conservatives in the senate may demand it be fully paid for before they approve. libby casey joins us live from washington d.c. libby casey, good evening. we saw some surprisingly

bipartisan support with the bill. why is that? >> that's right. it's something that both parties wanted to fix for a long time. they have done temporary fix 17 times. what is unique is they were able to compromise on something in a divided onnilent. it took nancy pelosi and john boehner, the house speaker, coming together and both were able to give up a little more ground. democrats agreed that some of enrollees would foot some of the bill. $35 billion of the more 200 billion price tags. that was a give. republican agreed it won't have to be paid for, and agreed to extending the health insurance programme and funding for health centers, something that democrats wanted. so it wasn't a magical formula. it was a simple process of give a little take a little and being willing to compromise what

is surprising is it doesn't happen pore office why didn't the senate take the issue up before recess? >> that footage from mitch mcconnell we heard from a 3am vata rama. the senate was going through a lot of things. they decided to wait and do this by the light of bay. the center was off. the centers for medicare and medicaid says there's a bit of wiggle room to get the issue resolved or doctors can see a drop. it takes about two weeks for the bill to in or longer if you do it by paper. there was a grace period. the senate doesn't intend to take it up. the crunch will be on.

it sounds like they'll get it done. it's never over until it's over. there are a couple of areas. some do want to see this pat for. some democrats are concerned about an aind apportion in this. nancy is a pro choice legislator said this is not a change in existing law, and a lot of caucus they support this in the mouse. house. we are not likely to see as many democratic defections. if everyone focuses on the idea of give a little take a little they should be able to pass it. you never know if the conservatives and the liberals will find a way to band together to stop something. >> thank you. stay with us as we talk about this issue. medicare of course is one of

the largest government safety met programs in the u.s. along with social security and unemployment. $54 billion elderly and disabled people rely on it. people are being told not to worry about the deadline. while debating the bill senators will focus on 141 billion impact on the deficit over the next 10 years, but a net saving will be noticeable in the following decade. to talk about this we'll bring in dr abdul, a professor at columbia university and a dancer with the robert wood foundation. she's in washington d.c. for us. both of you, thank you. snow i'll start with you here. how important is the issue that it brought both parties together supporting the bill

toot on a level like we have never seen. >> medicare is an important and large issue that we pay for. it's huge. we have known for a long time that folks on both side of the aisle hate the way medicare is paid for. this is app issue, rare issue in the national discourse that brings taght multiple sides on the same conversation. >> what do you think about this. >> it's an important plan. an aspect of this plan is it starts the conversation around how you pay for value. it incentivizes doctors to do things. starting to move the conversation towards how do you make a patient's health better is a good positive ol. the challenge is to define what better is. this is left a little up to depression and in this way is kicking the can down the road.

>> let me bring in ms denser. take us back to 1997. why was it mandated in the first place? >> well the volume of physician services under medicare has been growing. some worried because of the way we pay doctors, in a piece work basis, as if you were paying cobblers to make shoes, regardless of whether people wanted to buy the shoes or regardless of whether they were any good. so the incentives were for doctors to do more and more because they were paid on a piece work basis, and the rates were going up. congress said enough we have to come up with a formula where if the volume of services does go up doctors will be paid less so that the combined expenditure is not as great as it would be

otherwise. that was the rational for the programme. that would have dictated the big cuts in payments 17 different times. congress avoided the cuts as congressman john boehner said in the set up because the degree of cuts would be so big because the expenditures were going up rapidly. >> i want to say with that point. let me bring in libby casey. 17 years you pointed out the band-aid fixes, why did it take so long to tackle this. >> a lot was nuts and bolts trying to figure out how they could find a relaxing solution. congress focuses on a deadline approach. the thing about this ultimate change that is not a patch, but is a fix, is the biggest change in 20 years, that this has been

anti-produce. they are hearing from their doctors year after year i may not be able to serve you as your physician if the payment changes, and so that has been an ongoing lurching problem for medicare patients and frustration for the doctors. you talk to members of congress who are doctors on both sides of the aisle. they long wanted to fix this. it comes down to figuring out the right formula. take us through the counter process to let people know what goes on. how do they get paid. >> they'll see a patient and bill for the services. then medicare will pay the doctor for the services after the fact. this is the way that it works. you can imagine, as ms casey says, this causes a lot of

consternation on the doctors and patients behalf. the duration are thinking if you guys don't pass this we will not get paid for what you already did. doctors think i can find people and pay them they'll pay me for sure to i won't take medicare patients. this limits their access to care. this is why this is a patient and doctor level, a big issue. >> why do they need to tackle the idea of feed per service. the system some say, is possible for fraud, that some doctors would order more tests than needed to bet the reimbursements. >> it's sort of a cobbler making shoes for people that don't want shoes. if you get paid for a certain

thing, it's an analysis. when we go to the mechanic we boep know what is wrong. you don't know if they are telling you what is wrong or they are telling you. doctors who are incentivized getting paid for the shoes they make the incentive may be to upselling you, and that contributes to increase in costs in medicare services and that is something as a society, given the size of medicare that we want to bring down. >> the idea of value based care who determines the outcomes and how does it change? >> what hap sense that after five years where positions are paid the way they are, after the five years physicians have a choice to move to a different

payment plan. they are paid on the health of a catchment area a group of patient that they see. their goal is to improve help rather that to do services. that changes the incentives and the ability to bring down costs. this comes to the question how do you decide what quality is. you can talk to any number of populations and physicians and patients and ask what you value. the question we have to ask is which of those is worked in. that unfortunately is going to come down toed its to the law. that's why in some ways this is a permanent fix, and in some ways it's a difficult can. >> let me bring in ms denser. do you think this is god policy? >> absolutely. it's ridiculous to go though the exercise year after year where congress nose the cuts are

coming and forestalls them. as people said it's a distraction, gets us away from what we need to do as a country, which is shift the way we pay positions under medicare. one in three medicare beneficiaries are not affected because they are in a programme, medicare advantage. two out of three is in a traditional programme where the fee for service dynamic prevails. we need to move away from that. if we spend a lot of time we faent focus on innovative ways to pay positions. there are models that we are testing. we need to test models paying for value, and we really need to

test this out. >> this is going to cost a bit of money. the bill is talking about making resip grents to pay higher premiums is that pair? >> we charge higher income beneficiaries more. we'll charge them a little bit more for the part b of the programme, which is this position payment part and the drug benefit. this continues a trend we had in place for some time and frankly, we have to come up with a way to finance the medicare programme, and some think the fairest way is to ask people that are well off, to pay more. keep in mind 2% are in the category required to pay more. >> overall. do you thing this is worth the

hundreds of billions that this is going to cost. in the best case scenario if we move to a system where we pay doctors and ipp sent vice them we'll -- incentivize them we'll save money. we co get caught up in a narrow fight adding to the deficit, but what we need to do is revamp the programme. we have seen per person medicare spending very low for the last couple of years if terms of the rate of increase. we need to fall because we have so many more enrolling in medicare. over the long haul if we come up with a better way to pay physicians value not volume we'll save money. we'll spend more over the next 10 years to get ourselves to

that point. >> do you agree. one of questions that we have to ask is about the sustainability of the programme. we agree that medicare provides a fantastic service to the elderly, and a service that all wants to benefit from. the question is how do you make medicare sustainable. that is ultimately about lowering the costs. we need to turn to innovative methods, about how to get physicians to do the right thing, best thing by the patients and come out making a good living. this moves us in that direction. thank you all so much. here in new york. thank you all for joining us. before we go let's look at other events coming up in "the week ahead." monday - general election begins in sudan, incumbent president bashir who recalled the country for 25 years is expected to win.
