Protests a rep in brazil after former president lula the silva is brought in for corruption. A knife allegedly found at the former home of o. J. Simpsons ring invest gated. It puts spotlight on murders committed more than two decades ago. In the shadow where the trade desires where the world trade towers once stood, a new transit hub is a sight to behold. Welcome to our viewers on Public Television in america and also around the globe in the u. S. , we think our politics are full of drama. Brazil was gripped when the countrys former president was questioned by police. This is in connection with the biggest corruptions kindle to ever hit brazil. It involves the countrys state owned oil gile at oil giant. Outside lulas house, police clash with protesters, both supporters and detractors, as news of the former president s detention spreads. He was taken to a Police Station or three hours of questioning over claims he and his family had benefited from illegal payments. Evidence looking at that the former president and his family received advantageous payments. We are still at the investigation stage, but we found no plausible motivation for these payments. Released,er being lula was driven to the headquarters of the governing working party. He denied any wrongdoing. I have been hurt. I feel offended. I did not need this. I feel outraged, as if i was a prisoner. If they tried to get me, they have not succeeded. Julia this corruption investigation have dominated brazilian politics for months, but the investigation of former president lula signals a new stage and indicates danger for her and president s. For the current president. There is a scheme to divert money from petrobras through overpriced contracts. Organization, the lula institute, is under the spotlight. During his eight years as president , lula was the face of the brazilian boom. His detention is a significant moment. Is in asuch a figure criminal investigation, it should send a message to the whole country that nobody is above the law. Developments increases pressure on president rousseff, already presiding over a failing economy. ,he fact that her predecessor the symbol of her party, was brought in by police, it makes it a dangerous moment for her. Laura for more on the events unfolding in brazil, i spoke with eric farnsworth, Vice President of the american society. Lula is this towering political figure. How significant is it that he is even being questioned by the police in relation to this Corruption Scandal . Eric this is a big deal for at least two reasons. Not the least of which, it shows the world brazilian justice will go after whoever they want to go after and nobody is above the law. I think that is a particularly significant development, particularly in this context. Number two, lulas iconic. He is a leader of a movement. He was the first president elected from the working class. He represents the aspirations of the long downtrodden in brazil. Really the impression may be somemer forming among sectors in brazil that by being questioned, he is being made into a target by forces that they would not like to really have to confront. This is really a very interesting time. Laura lula says it is a witchhunt and Brazil Police do not want him to run again for power. Is there any truth in that . Eric you know, there may be truth that some people dont want him to run again, but i think that in a Law Enforcement investigation, you have to divide the legalities of the issue from the politics. It is tough to do. I am not saying it is easy to do. They are all intertwined. This process has to work itself out. There are many people in brazil who are being investigated for corruption. This is something that brazilian public is having to deal with as well. Laura could this affect brazils current president , Dilma Rousseff . Eric it could. She is directly linked to the scandal and there are investigations going on in congress. This gives new life to those in congress who want to impeach her. Yes, it does have a political component. You put it in the broader context, brazil had a difficult year economically last year. This year will be difficult. They have divisions in society. This will paralyze elites in the country and it will be difficult for them to find the path forward to get out of this. Laura the allegations are all about this state owned oil company. Why is it so central and engulfing so many people . Eric there is a lot of money involved, number one. Number two, it seems this money has been used for overtly political\ purposes. Pride foris a real the brazilian people. It is a National Energy company. It is a company that has been world class, and it has done things from a technical perspective and contributed to the brazilian economy. Put all those together it really , does become a complicated political issue. Laura are there lessons for brazil and having strict anticorruption laws . Eric this is a process that a lot of people have said is ultimately going to be good for brazil because, yes, there is corruption. There is probably corruption in every country. To have an independent process that can investigate and profit and prosecute where that needs to occur, but also to clean out corruption as it occurs, this will make a stronger brazil if and when this process concludes. There is a way to go. Laura thank you very much for joining us. Forensics investigators in los angeles are testing a knife reportedly found on a property owned by o. J. Simpson. The former football star was acquitted of murder charges in the stabbings of his exwife Nicole Brown Simpson and her friend, ron goldman. The l. A. Police Department Said the knife came to light last month. James cook has the latest developments. James it was the trial of the century. O. J. Simpson accused of murdering his exwife, nicole, and her friend, ron goldman. A bloody glove which did not appear to fit was at the heart. Orenthal James Simpson not guilty. James it felt like the whole world was watching. At first, simpson had run, fleeing in this white vehicle with police in hot pursuit. A murder weapon was never found. Or was it . When simpsons house was demolished in 1998, a knife was reportedly discovered and handed to a police officer, who kept it to himself until now. I do not know whether he was retired at the time that he allegedly received this item from the person who claimed they found it on the property or he was still in fact an lapd officer and retired sometime after that. It is being treated as we would all evidence, so it has been submitted to our lab. They are going to study it and examine it for all forensics, including dna and hair samples and that is ongoing. , james the law of double jeopardy means o. J. Simpson cannot be tried again, but his Court Victory was hollow. He lost a civil case brought by the victims family and is serving 33 years for armed robbery. He can apply role next year. This extraordinary story, it seems, never ends. James cook, bbc news. Laura in the never ending development in the u. S. President ial race, today ben carson suspended his campaign. That leaves for candidates left running for the republican nomination. Frontrunner donald trump shot back at some recent criticism and left many shaking their heads. Trump i have to say this. No one has ever hit my hands. Look at those hands. Are they small hands . [applause] and he referred to my hands. If they are small Something Else , must be small, i guarantee this. No problem. Laura i spoke a brief time ago with amy. I had to gloss over that hand reference to my nineyearold son this morning when we were watching tv news headlines. How long can this race go . Amy what the brits must think of us. I did not think it would go this low. I did not think we had it in us. It has gotten really bad. The problem with this ross s is when it goes this low, you can never get it. A new low. This is a new level of combatant, degraded combat in politics that even unthinkable a year ago. Laura donald trump did take a lot of incoming fire last night from his opponents. Is any of it going to make a difference when nothing has stuck . Amy i think his supporters are never swayed. When he has a bad debate night, they dont care. When you show him in focus groups flipping and flopping, they never care. Latebreaking deciders, people having a contest coming to their state and they dont Pay Attention until five days before, they had been going largely with marco rubio. That could have an effect for the nontrump candidates. The problem is if that number is nicely split, it is still in advantage for trump. Laura florida, ohio are up for grabs. Is it crucial for marco rubio to win florida . If he doesnt, is the race over . Amy governor kasich said if he does not win the six electoral votes delegates, excuse me, in ohio, he would have to leave, implying that if rubio did not win the 99 in florida he would , have to leave. I am not sure. Are really digging in for a threeway block for trump, slowing his momentum so we cannot reach 1237 delegates before july. It might seem farfetched it , might seem desperate, it might seem impossible, but it is a realistic possibility and i dont know if we will be at this for five more months. Laura the Republican Party establishment seems to be pinning their hopes on their strategy, doesnt that . Amy yes. Theyre willing to burn this down and die trying to stop him. They dont believe he is a republican and they know the party is broken and sort of on the deathbed. He will read it the last rights. They dont want him to be the head of the Republican Party. They are willing to try to block him and fail or rename their party and join another pursuit. It is unthinkable, but they think it is worth burning the house down to save the party from donald trump. Laura one thing this race has shown is a lot of enthusiasm, high turnout on the republican side. How worried is that have Hillary Clinton . Amy it should worry clinton very much because his ability to turn out firsttime voters or voters who have not been engaged in politics for 20 years and create a new coalition is a threat to her. Laura thank you very much for joining us.

There is growing evidence of a link between the zika virus and two neurological disorders. Travel warnings remain in place for many countries. A vaccine for the virus could be ready for human trials by september. Correspondent visited the Research Site in maryland and has this report. It is an enormous challenge, but answers are becoming clear. Scientists are using Genetic Information from the zika virus to make a new vaccine. Put those plasmids inside a bacteria, and the bacteria dr. Barney graham heads up the research team. They are developing bacteria that will be used as the active agent. The challenge is that we dont know much about zika. Vaccines are not made quickly. Typically, vaccines take decades to develop. Once you have discovered a virus, most vaccines, to deploy to the public, would take at least 20 years on average. This is a little image of it. There are little circles. The circles are the zika virus. New technology and techniques are changing that. Scientists are developing a vaccine for a similar virus, which has given them a bit of a head start in this Global Health emergency. It seems to be spreading quite quick, and we dont have that much time. We need to act as quick as possible. It starts off, my early training at the New York HospitalCornell Medical Center this is the man charged with ensuring the u. S. Gets this vaccine fast. There have been 100 imported cases of zika in america. We will have vaccines ready to go into humans to test, not to distribute, but to test, for safety and for whether it induces a response that you would predict would be protective. That phase one trial, i believe, will likely start towards the end of the summer or early fall. When i see pictures of microcephalic babies, it gives me the force and energy to know that is is a very serious problem that we have to have all hands on deck, everyone doing what they need to do. It is already too late for these babies in brazil who are facing a lifetime of disability. Many more will be born this way before a vaccine is available. Despite these scientists efforts, the earliest a vaccine could be widely distributed is 2018 or beyond. It was these scientists who help develop in a active vaccine vaccine vaccine against ebola. They want to do the same for zika. They are racing to get a vaccine ready in the hope they can prevent more babies being born braindamaged. Laura trying to create that the sica vaccine. Zika vaccine.

Its symbolism is lost on some. It has been likened to a turkey carcass the day after thanksgiving. A bird, right . Seagull . I dont really see a bird. What do you think of it . I know its supposed to represent a bird, but i dont know. Thats america for you. For others, it has become instantly iconic and perfectly, and perfectly complements the 9 11 memorial. I think it is a fantastic way for the city and visitors to always look up and be inspired instead of feeling dragged down by the nightmare of 9 11. In lower manhattan, the skyline has in repaired and the station has a cathedrallike home, but it is hard to see a plane in the sky without remembering the monuments that stood here before.

It is also thought he had help from friends. One of the problem with botticelli is he had a large workshop that would paint paintings to his design. How can you tell which are by the master and which ones are by the assistance . To answer this question, i have tracked down the shows curator. Botticelli or assistant . This is one of the masterpiece exhibitions. From absolutely beautiful the early phase of his career. ,he position of the landscape this still life here, everything is absolutely exquisite and of a high degree of finish. This Quality Speaks for botticellis authenticity. Will these portraits are a highlight of the show. They are stunning.

They admired the simplicity of botticellis line and taste in design. Rossetti went as far as im one of his paintings, to which it is said he added a touch or two of his own.
