on tuesday. michigan and mississippi are holding their democratic and republican primaries while in hawai'i republicans are ar are casting their votes. flint, michigan, where they are dealing with contaminated water. >> what happened to flint. >> as they vie against each other, they are united for help on the taint tainted water. >> it is my home people look at flint and say never again. >> they campaigned here and clint sent in her top political adviser. >> frustrating? >> absolutely.

things should move faster. if there is anything right now, congress should be working together, republicans and democrats, it really is about flint. >> there is a lot of media attention and put a lot of pressure on politicians in d.c. to do something for flint. >> they switched their water source to save money. flint residents are still bathing in water tainted with lead. they line up at five fire station for drinking water and tally the damage to their children. >> i've lost unborn twins. both of my kids tested positive for high levels of lead. after this campaign what will mr. bernie do to help the city of flint? in five to ten years what is going to happen to my kids? >> the flint residents we talked to said that they're glad politicians are finally paying attention to problems that started when they switched their water source to the corrosive waters of flint river.

but to fix the pipes would cost $1.5 billion, and zoo far no one is offering that. now that flint has returned to buying its water from detroit, simply restoring the anti-corrosive chemicals they should have been using all along will vastly improve the water quality. >> the system through properly adjusting the water chemistry can be restored to the situation where safe water has been delivered. well, that by itself restores confidence? probably not. >> flint residents has not had confidence in their government since water pipes have been deteriorating for decades. in washington congress is debating sending as much as $200 million, a drop in flint's tainted bucket. >> well, kimberly halkett is in washington, d.c. and joins us

now. hi, kimberly. how can the vote change the democrat's current standing? >> well, it would give the opportunity if bernie sanders did win in michigan, which is, of course, the big prize as you pointed out as well as mississippi. it could really give them a chance to try and close that gap that hillary clinton has. she's very far ahead in terms of delegates she has collected three times bernie sanders. that included the superdelegates that holds a lot of sway at the party nominating contest at the convention that will be held in july. so as a result, that's what the sanders campaign is hoping will happen on tuesday. the reality is that hillary clinton has a very solid lead. she's polling in those key states ahead of bernie sanders. he has not been able to make traction on the types of voters that are voting on tuesday, today. that is voters of color, women. this is this is hillary

clinton's chance to cement herself as the presumptive nominee. >> kimberly, the republican party is in turmoil as to stop trump's current lead. what is at stake? >> turmoil is a very nice way of putting it. there is really panic going on when you talk to some of the republican operatives that are sort of privately very concerned about the prospect of donald trump being the party's nominee. as a result we saw a very prominent republican. mitt romney, a former presidential candidate making telephone calls to voters urging them to not support trump in this poll. and in fact,, to go with one of the more established candidates like ted cruz or marco rubio or even john kasich. the concern is that polling shows if trump is the republican nominee, that hillary clinton, she's the democratic nominee, would defeat him. there is not only concern about donald trump as the republican party's nominee, but also the

potential of a loss in november. >> kimberly halkett there joining me live from washington, d.c. thank you. >> the families from the malaysian flight 370 are holding vigil. we have more on the investigation to find the wreckage and the anniversary. >> the second anniversary of the disappearance of flight mh 370 was marked in malaysia in a low-key manner. the politicians held a minute of silence to remember all 239 people who were on board that plane when it disappeared. a team of international investigators also issued an interim report. according to the international civil aviation organization, an interim report has to be issued on each anniversary of the accident until the final report has been issued. this is the second interim report, and unfortunately, it

does not disclose any new information or any information that is not already in public domain. there was issued a statement on tuesday on the anniversary saying officials are doing all they can to find the plane and to solve what is being described as the biggest civil aviation mystery in history. now two rather encouraging pieces of evidence have been found. one piece of di bri debris on union island and the other in mozambique. now they'll investigate whether this comes from the missing mh 370. they expect the operation to come to an end in july this ye year. at that point three countries, china, australia, and malaysia will make a decision whether or not to continue the search

operation. >> lawrence lui reporting there. venezuela is searching for gold miners who failed to return home from work. so far investigation investigation have failed to find any bodies. >> the authorities have begun investigating allegations that 28 miners might have been massacred in the southern state of bolivia. family members of 28 men took to the street, a small town in southern benz to protest the disappearance of their loved ones. they're claiming that these men never came back from work after friday. eyewitness accounts describe a scene of carnage where several of these men were shot and dismembered, and the remaining parts of their body was thrown into a truck that was driven away. the government initially said that these allegations could not be proven, but have now moved to

send in investigators also the ombudsmen to look at the testimonies of the families of these men. this area is very rich in gold and diamonds and has traditionally seen not only legal but also rampant illegal mining. there is illegal mining is said to have gotten worse in the last couple of years when as many as five criminal gangs took control of the area. the opposition said that this possibility of the massacre only highlights how lawless this area is, and has said that these criminal gangs could only work in this area with the cooperation of corruption military force. the government is looking into the allegations, but as of now no official statement has been put forward. >> the so-called dentist of horror has gone on trial in france. he has been accused of assault and fraud after allegedly terrorizing patients and removing healthy feet. he fled to canada when suspici

an artificial system developed by the google project named deep mind. he beat the champion last year 5-0. now it's designer said they want to learn by playing the game's greatest. out of that they want no arguments once they've beaten him. >> we've chosen him because we want--we think this is going to be a very historic match, so we wanted a legendary historic player, somebody who has been at the top of the game, and acknowledged as the greatest player in the last decade. >> the game is quite simple. the complexity especially for a computer lie in the sheer number of options available for each player and helps to determine what makes a good move. to win a game of go you want to control the maximum amount of territory on the board. you'll choose the lines where you place your pieces. trying to avoid at all costs

being surrounded by your opponent. because at that point they vanish. among these young enthusiasts there is no doubt about the likely winner. >> i think there it's more about technical moves. >> i think it will win because when it comes to go humans are more intelligent than computers. >> they tried to find a way to combat human intuition rather than trying to compute over possible outcome in every move. the first looks at the choices and then stimulates the out come at that moment. what if go actually wins? >> if they can do that, that will be a different paradigm of application. >> they say that this will be an historic match. people are hoping that it is an
