The only republican that beats clinton is john kasich. Now have a look at this. Bernie sanders does clinton one better. He beats all of the republicans, trump by 17 points. Sanders and clinton are debating in brooklyn tonight five days before the new york primary. Heres nancy cordes. Our Campaign Today has the momentum. Anheering and applause] reporter sanders drew one of the largest crowds of his Campaign Last night, more than 15,000 people in greenwich village, but he admitted clinton still has the edge. And this is a tough race for us. Reporter clintons large lead in pledged delegates is poised to grow next tuesday, which has sanders supporters increasingly eyeing superdelegates, the roughly 700 Party Officials who overwhelmingly back clinton but are free to switch. One sanders supporter even posted a superdelegate hit list online, complete with names, e mail addresses and phone numbers. How in the hell could you sponsor hillary over bernie . You should be ashamed of yourself. Reporter Akilah Ensley is one of many superdelegates who say theyve been deluged with hostile Facebook Messages and e mails. There have been some rude names used. Theres been a knock at my character and my intelligence as to why i would be supporting someone that they see as the establishment. Reporter the Sanders Campaign says it doesnt employ those tactics or condone them. Aides are working quietly to woo superdelegates but would need to convert hundreds of them to make a difference. We think theyre ridiculous rules. Reporter jane sanders told cbs news digital journalist kylie atwood that the superdelegate system should be eliminated all together. Its an insurance policy for eye establishment to make sure they dont get somebody they dont want. Reporter superdelegates were introduced in 1982, and they typically only switch allegiances when the candidate they backed initially begins to fall behind, as clinton did in 2008. They have never subverted the popular vote, scott, and they dont appear poised to do so this time. Pelley nancy cordes, thank you. Americans dont seem to like their choices very much. Our new poll shows three candidates have a big problem with likeability. 54 of registered voters have an unfavorable opinion oflinton. For trump its 63 and cruz 48 . One thing trump doesnt like is the g. O. P. Rule book for winning delegates. And heres major garrett. Its the politicians. Reporter donald trump cant stop complaining about republican nomination rules, especially after losing all 34 colorado delegates to ted cruz at the state Convention Last weekend. People are just furious. The republican folks, theyve taken their vote away. They didnt even have the right to vote, and i think its a very sad situation. Reporter cruz said his betterorganized campaign won fair and square. My focus is on winning because donald as the nominee doesnt win, he gets clobbered by hillary clinton. The stakes are too great. Reporter last night cruz accused Trump Supporters of using threatening tactics in colorado and indiana and seeking to intimidate antitrump delegates at the g. O. P. Convention. Theyre acting like union boss thugs. Reporter the fight might not end at the convention. The latest cbs news poll shows 63 of Trump Supporters want him to run as a Third Party Candidate if he loses the nomination. Although probable cause exists, the state will no file this case. Reporter Trumps Campaign did clear up one matter today, Campaign ManagerCorey Lewandowski will not be prosecuted for simple battery after grabbing a reporters arm in march. Palm beach county prosecutor david aronberg. While the evidence in this case is legally sufficient for the police to have charged mr. Lewandowski, it is not Strong Enough to meet the legal burden of a reasonable likelihood of a conviction. Reporter lewandowski broke the news to trump during a meeting. Lewandowski thanked trump for his steadfast loyalty. Trump said lewandowski wasnt quite as effective for the last couple months. Pelley major, thanks. In another important story, the u. S. Destroyer buzzed by russian fighters this week had the right to open fire, according to secretary of state john kerry today. We asked david martin to tell us why the russians are tempting fate. Reporter u. S. S. Donald cook pulled into port in a thuania for what was supposed to be a goodwill visit to a nato ally but turned into a press conference about its runin with russian jets. Ommmander Charles Hampton said he had seen them coming from a long way off. We tracked them for a length of time. I had a track on both aircraft 100 nautical miles away. Reporter they kept coming, very fast, very low and very close. They were flying what appeared to be a mock attack, although they were not carrying any weapons under their wings. The cook was operating in the baltic sea in International Waters 70 miles off the russian enclave of kaliningrad. The flyby seemed intended as a brushback pitch to warn American Forces not to get so close, but the ships captain plans to ignore the warning. This u. S. Navy will continue to operate forward, continue to rserate with allies and partners. And planned events at sea, in doing, so we will not cede space. Reporter this map explains why russia is pushing back. Since the end of the cold war, the Nato Alliance has expanded from the border of germany right up to the edge of russian territory. Nato aircraft now conduct exercises with countries that used to be part of the old soviet bloc. And russia wont like whats coming next. In june 13,000 u. S. Troops will take part in a largescale military exercise in poland, one of the largest since the end of the cold war. Pelley david martin at the pentagon. David, thank you. Well, the u. S. Should be preparing for war against the zika virus. But congress has not put up the nearly 2 billion that the c. D. C. Says it must have. Mosquitoes are soon likely to spread the virus here. So our dr. Jon lapook went to washington and extracted a promise. Reporter when the administration moved nearly 600 million from fighting ebola to fighting zika, dr. Anthony fauci of the n. I. H. Said its a stopgap measure at best. When the president asked for 1. 9 billion, we needed 1. 9 billion. Reporter House Speaker paul ryan. Mr. Speaker, do you believe the white house when it says it needs the full 1. 9 billion to fight zika over and beyond what has already been allocated to fight ebola . The money is in the pipeline. Our appropriators are going to address this issue if the need ever arises. Our appropriators will address it in the appropriations process. But the money will be there eventually . Reporter congressman tom cole chairs an appropriations subcommittee considering the administrations request. Who decides whether its truly needed . Do you believe the n. I. H. . I actually do believe the n. I. H. And we do believe the c. D. C. , but we have to use the resources that we have wisely. We need the money now. Reporter democrats in the white house favor an emergency request, which doesnt need to be funded at the expense of other programs. House minority leader nancy pelosi. The budget process takes a long time. It will be practically nine months before we could ever get any other money, and its no guarantee that you have it at the end of the year. Reporter at the end of the day, that money will be there or it wont be there . I dont know. I honestly dont know, and that nd what is. That has us very concerned. Reporter but congressman cole says he understands the importance of funding. You have our guarantee that we will work with you on this. Reporter do they also have your guarantee that the money will eventually be there if its truly needed . Yes, they do. Reporter scott, just yesterday the c. D. C. Confirmed zika causes birth defects. That makes it all the more urgent to mount a fullscale assault against the virus and mosquitoes that carry it. Pelley jon lapook, the best doctor on capitol hill. Jon, thank you very much. An independent review of the Chicago Police has found ersregard for African Americans who the report says are often stopped without justification, physically abused and detained without counsel. The investigation was ordered by the mayor. Dean reynolds has the report, which is being called a light shining into darkness. Reporter the Police Accountability task force shed a harsh new light on an old problem. Lori lightfoot chaired the panel. Many people said that they believe that the police that they encountered were fundamentally racist. Reporter she said the departments own data validates a widely held belief the police have no regard for the sanctity of life when it comes to people of color. Between 2008 and 2015, 74 of people here shot or killed by the cops were black. 76 of the time police used tasers, they used them on black people. They are killing our children. Reporter as protesters took to the streets over the shooting death of a black teenager by cops this week, the report was urging changes in police union contracts, which it said encourage a code of silence that protect bad officers. Mayor rahm emanuel. So the question isnt do we have racism. We do. The question is what are you going to do about it . Reporter the mayor picked the panel after the 2014 death of 17yearold Laquan Mcdonald at the hands of a white policeman who shot him 16 times and later claimed his life was in danger. Among the reports 100 recommendations, a citywide reconciliation process beginning with an acknowledgment by the police of their history of bias, a hotline for police to report wrongdoing, and an expanded use of body cameras. Andy shaw is with the better government association. The lack of accountability is staggering, and more staggering, why havent we collectively done more about it up until now . Reporter and its an expensive problem, too, scott, because over the last 12 years, the city of chicago has had to shell out some 650 million to settle cases of police brutality. Pelley and just yesterday chicago swore in a new African American police superintendent. Dean, thanks very much. Nine people have been killed today in an earthquake in southern japan. This is what the 6. 2 quake looked like in a newsroom. Dozens of homes collapsed, fires broke out in a number of cities, several aftershocks have been felt and there has just been another quake, 6. 5, near the Pacific Island of vanuatu. Two years ago today, the islamic d rrorist Group Boko Haram kidnapped 276 schoolgirls in nigeria. M,spite a Worldwide Campaign to free them, more than 200 are still held. Now we are seeing some of them for the first time in a terrorist video. Debora patta has it. Reporter soft spoken, eyes down cast. The girls answer the voice off eymera. Theyre being treated well, but they want to go home. Boko haram claims it made the video last december. We cant verify the date, but today parents from chibok instantly recognized the girls in the video. Esther yakuba was devastated when she didnt spot her daughter. Two years after the girls were kidnapped, their school lies abandoned. The Nigerian Government has been unable to free the girls or even find them. A source close to the negotiations told us boko haram demanded a large ransom and a prisoner release in exchange for the girls, but it all fell apart when the government refused to pay. According to human rights group, boko haram has kidnapped over 2,000 girls in the last two years. Those who manage to escape often end up in refugee camps in neighboring cameroon. They tell harrowing stories of rape, being forced to marry the fighters, even being groomed as suicide bombers. Bring back our girls. Reporter today relatives of the missing girls accuse the government of failing to put aiough resources into the search. All we want, said one, is for the government to bring back our girls. For now negotiations between the Nigerian Government and boko haram have completely stalled. There have been reports since the kidnappings that some of the girls might have been moved out of the country or even killed, but the bottom line, scott, is that two years on, not a single chibok girl has been found.

Pelley beaches off cape cod are packed months ahead of tourist season. The visitors are in no hurry to leave, and we sent don dahler to check it out. Reporter a pilot flying over monomoy island this week captured a stunning image, miles and miles of gray and harbor seals basking in the spring sun. Its not unusual to see seals here this time of year. Whats unusual is seeing this many from this perspective. Marine biologist owen nichols has studied them for 15 years. Why has the seal population increased over the past few decades . They were essentially exterminated, extirpated from our waters right up until the 1960s. So youre seeing a re colonization, a resurgence. Reporter and theyre not hunted because theyre federally protected. Thats correct. Reporter before 1972 when the Marine Mammal protection act went into effect, sightings of even a single seal were rare. But today we spotted hundreds on the uninhabited nature reserve where the aerial video was shot. Heologists say the resurgence of seals here is likely one of the reasons theres also been a rise in the number of sharks in these waters looking for food. Researchers counted 68 great whites off cape cod in 2014 that number doubled to 140 last year. But the hoards of seals are not only attracting sharks. Local fishermen like doug feeney say theyre eating too many fish. To us as fishermen, its way too much. Its very taxing on them. Reporter an 800pound male could consume up to 6 of its body weight each day. Thats 50 pounds of fish, including valuable species like cod, flounder. Feeney and the biologist nichols are part of an alliance of fishermen and scientists. Roott, theyre trying to find middle ground between conservation and protecting the livelihood of the fishermen. Pelley don dahler at the beach for us. Don, thanks very much. You couldnt have scripted a better ending for one of the nbas alltime greats. Thats next. Flare was almost always on my mind.

Kpix 5s len ramirez joins us. The case started after a group of students, some from oakland, sued. Len. Reporter thats right, this is being hailed as a big victory for the unions. But it may only be a temporary victory, because the plaintiffs are already saying they are going to appeal this to the california supreme court. Now, at issue are the rules for teacher tenure in california and how that can affect a schools ability to fire bad teachers. Now, the plaintiffs are a group of parents who say their kids got stuck with bad teachers. The lawsuit said giving teachers tenure after just two years hurts students because it becomes very difficult to fire even the ineffective ones. But today a threejudge panel overturned the ruling that threw out tenure and other job protections for teachers. This is a clear victory for the unions. This is a victory for students and teachers. If this was allod
