drafted for the last convention. >> reporter: the once-fanciful idea of a contested convention is now so real, no interested party can afford not to plan ahead. the rnc is recruiting rules experts. so is trump, so are his rivals. scott, this could be the billionaire real estate developer's biggest art-of-the-deal challenge ever. >> major garrett tonight. major, thank you. by the way, today, illinois state police and the chicago p.d. dropped charges against cbs news reporter sopan deb. deb was covering the unrest at that canceled trump rally in chicago on friday when officers pushed him to the ground and arrested him. deb was charged with resisting, but he was cleared after a review of video and interviews with the officers. late today, bernie sanders conceded the close vote in tuesday's missouri primary, meaning that hillary clinton swept all five states. democrats are looking ahead now to a possible trump nomination and asking themselves whether the billionaire will help them win back the senate.

republicans have a four-seat majority, but they have 24 seats up in november, and the democrats have only 10. here's nancy cordes. >> reporter: arizona senator john mccain has called trump's views uninformed and dangerous. but that hasn't stopped his democratic senate challenger, anne kirkpatrick, from running ads like this. >> no matter what donald trump says, john mccain would support him for president. >> reporter: new york senator chuck schumer warned today that strategy will be replicated in dozens of races across the country. >> donald trump won't make america great again, but he will make republicans minority again. >> reporter: unlike mccain, many republicans have been reluctant to outright denounce trump. they fear that weakening the likely nominee will lead republican voters to stay home in november, hurting gop candidates down the ballot. but today, the senate's democratic leader, harry reid, said that silence is giving his

party fodder, too. >> some of these people are running for reelection. rob portman, roy blunt. i just don't know how these people could run and say why i'm supporting this guy for president. he can't-- and he can't run away from it. he's the nominee. >> reporter: republicans point out they're the ones seeing record turnout in the primaries, while democratic turnout is down. but, scott, democrats insist that if trump is the nominee, their base will flock to the polls in november to vote against him. >> nancy, thank you. an american who joined isis and surrendered in northern iraq this week spoke today about his ordeal. mohamed jamal khweis is a palestinian american from virginia. he says he joined the terror group in december and quickly figured out the lifestyle was not for him. >> at the time, i-- i made the decision to go because i wasn't thinking straight. i didn't see myself living in that environment.

i would -- you know, i wanted to go back to -- to america. >> we don't know when khweis will return to the u.s. but the justice department is preparing to file charges. in iraq today, our elizabeth palmer was told that isis is running short of money because of the u.s. bombing campaign. liz got a rare interview with president obama's special envoy to the region, which said russia may be tired of propping up the syrian dictator. >> reporter: for the past six years, russia's government and its military have shown unwavering support for syrian president bashar al assad. but that, at last, may be changing, says brett mcgurk, the president's special envoy on iraq and syria. >> i think there's an emerging international consensus, and i include the russians on that, that without a very serious political transition, this conflict is going to continue to grind on and that's in nobody's interest. >> reporter: consensus on shutting assad out of syria's

political future would be a breakthrough and give fresh energy to the peace talks currently under way in geneva. while on the battlefield, where an international coalition has joined forces against isis, there's already been steady progress. a new report shows that over the past 15 months, isis has lost more than a fifth of the territory it controlled in iraq and syria. and, says mcgurk, strains are showing in other ways, too. >> so now, cutting salaries for their fighters by almost half. when they store money in mosul, for example, we find out where that is, and we target those sites. >> reporter: bomb the money. >> they can't pay their fighters. they can't communicate with their fighters. they can't move around the battlefield like they could before, and they can't hold territory. >> reporter: isis is still holding a huge amount of land, as well as two major cities, but if the current momentum holds, it's just possible isis territory will continue to

shrink as the outline of a peace deal in geneva slowly takes shape. and, scott, we may get some more details on that peace agreement, or ven maybe an inkling of what's in store for president assad when secretary of state john kerry goes to moscow next week. >> liz palmer with the key interview tonight in northern iraq. liz, thank you. a texas cop has been charged with murder in the death of a 16-year-old. and we'll remember the chairman and we'll remember the chairman of the b i think we should've taken a tarzan know where tarzan go! tarzan does not know where tarzan go. hey, excuse me, do you know where the waterfall is? waterfall? no, me tarzan, king of jungle. why don't you want to just ask somebody? if you're a couple, you fight over directions. it's what you do. if you want to save fifteen percent or more on car insurance, you switch to geico. oh ohhhhh it's what you do. ohhhhhh! do you have to do that right in my ear?

a police officer in a dallas suburb is charged with murder in the shooting of a 16-year-old boy. the officer's lawyer says he fired in self-defense. here's david begnaud. >> reporter: in an emotional farewell, hundreds of people said good-bye today to 16-year-old jose cruz at a small church in addison. cruz was fatally shot four days ago by off-duty officer ken johnson. johnson said he witnessed the teen and his friend burglarizing a car at this apartment complex. officer johnson confronted the boys, who then took off in cruz's vehicle. johnson pursued them in his own car, ramming into the teens at this intersection. eyewitness photos then show johnson getting out of his car and pointing a gun at the two teenagers. moments later, he shot the two

boys, killing cruz and injuring his friend. farmer's branch police chief sid fuller. >> we have policies that deal with off-duty enforcement that we all follow. >> do your policies involve an off duty police officer to chase suspects in his own vehicle? >> no. >> reporter: cruz's mother has been inconsolable, attending community vigils where hundreds of people have been protesting against the police. cruz family spokesman carlos quintinilla. >> what this officer did is he thought he had sovereign immunity. he thought he was in the wild west. he thought he was a vigilante. this is a cold-blooded murderer who murdered a 16-year-old, innocent young man. >> reporter: here's where it happened. that's the intersection where the officer rammed the vehicle, and i am standing in the spot where the shots were fired. scott, that officer who was charged with murder, that arrest happened yesterday, but by this morning, he had posted a $150,000 bail and walked out of jail. >> david begnaud tonight.

david, thank you. there are big changes coming at seaworld, and we'll have them next. today, seaworld said it will phase out its killer whale shows, giving in to pressure from animal rights activists. here's ben tracy. >> reporter: seaworld is ending

the shows that made shamu a household name. the company will also no longer breed its captive orcas. seaworld ceo joel manby on "cbs this morning"." >> so this will be the last generation of orcas at seaworld. obviously, that's a very difficult decision for us, but we feel it's the right one for the future of the organization. >> reporter: seaworld still holds 23 orcas in captivity at its three parks in san diego, san antonio, and orlando. the highly critical 2013 documentary "black fish" was the beginning of the end for seaworld's killer whale shows. it chronicled attacks on seaworld trainers such as dawn brancheau, who was killed by a massive orca in 2010. attendance has been falling at the parks, along with seaworld's stock price. the company is now entering into a $50 million partnership with the humane partnership, the one-time adversary. ceo wayne pacelle. >> we're hoping to partner with them to help with animals in

distress-- stranded whales, stranded dolphins, stranded sea turtles. >> reporter: seaworld was running out of options. the california coastal commission ruled it could not expand its san diego park unless it ended orca breeding. california congressman adam schiff said seaworld does dnot suddenly see the light. >> i think it is mostly a decision based on the fact that people were not showing up at the parks. people did not approve of the continued captivity of these whales. they didn't approve of how they were being exhibited. >> reporter: now, the orcas will still be on display at seaworld parks, such as this one here in san diego, but in what the company calls more natural orca encounters. scott, seaworld made a lot of money selling orcas to theme parks around the world, something they say won't do anymore. >> ben, thanks. frank sinatra, jr. has died. the chairman of the board's son became a singer himself. at 19 he was kidnapped and returned after his father paid the ransom. he went on to become the keeper of his father's flame.

frank sinatra jr. died of a heart attack yesterday. he was 72. and we'll be right back.,,,,,,,,

march madness is under way, and we end tonight with a team that didn't make it in, though they put on quite a show. here's elaine quijano. >> reporter: monmouth university's basketball team had its best year ever. >> we get the battering ram. >> reporter: but it may have been their bench that put them on the map. >> it got pretty legit pretty quickly. >> reporter: greg noack and dan pillari are the unofficial leaders of the bench mob, a bit of sideline theater to get the team and the crowd going. >> bench is never known as a cool place to be. so we kind of revolutionized it

a little bit where it's okay to be on the bench and support your team because it's a group effort. >> reporter: the group rehearses its celebrations before games, playing off current events, pop culture-- >> "star wars." >> reporter: and sometimes a little bit of history. during their victory in december over basketball powerhouse georgetown, they unveiled what they called the sistine chapel. >> look at that. that's the sistine chapel. that's my favorite one. >> reporter: what do your teammates say about it? >> they love it. >> reporter: do you feel like it helps them? >> absolutely. if they look over at the bench and see we're in the game and we're energized and trying to feed energy to them. they'll be like, if they're in it, how can i not be in it. >> reporter: basketball teams across the country have picked up on their antics. high school teams and even nba players have copied their celebrations. coach king rice. >> i really preach having fun, especially to my guys. you should have fun when you're doing what you love. >> reporter: doing what they love while changing attitudes

pabout riding the pine. elaine quijano, cbs news, west long branch, new jersey. that's the "overnight news" for this friday. for some of you, the news continues. for others, check back with us just a little bit later for the morning news and "cbs this morning." from the broadcast center in new york city, i'm scott pelley. -- captions by vitac -- www.vitac.com

this is the "cbs overnight news." >> welcome to the "overnight news." a major victory for animal rights activist. seaworld announced it will end it's killer whale shores and ending its orca breeding program. the shakeup comes after years of controversy about how the whales are treated in captivity and is being praised by the humane society. norah o'donnell has more. >> reporter: for years, animal advocacy groups have argued the family friendly shows at seaworld hide a more troubling

below the surface. the company disputed many of the film's accusations of animal abuse and neglect, but since the film's release, seaworld's stock price and park attendance have plummeted. "blackfish" tells the story of a trainer killed six years ago by an orca named tillicum. since then, seaworld no longer allows trainers in the water with the killer whales. the company has since instituted other reforms. seaworld says it's replacing its shows with shows that highlight the while's natural behaviors in the wild. but critics said the changes do little to improve the animal's living conditions. >> there you go. >> reporter: and the bad press continues for seaworld.

tillicum remains in captivity. the people who run the los angeles zoo say they're forgiving a local mountain lion for eating one of their koalas. it's also the only local predator capable of scaling an eight-foot wall. since the killing, there's been a raging controversy over what to do about p-22. shoot him, relocate him, or leave him alone. the zoo now says just let him be. john blackstone reports. >> reporter: other animals at the los angeles zoo may have witnessed the crime, but they're not talking. the victim was kalarney, a 14-year-old female koala mauled to death. the main suspect is well known to authorities, and most everyone else in los angeles as p-22, the hollywood mountain

lion. zoo director john lewis. >> what we know at this point is it's circumstantial, but he was in the zoo the night that the koala disappeared. certainly would be capable of doing it. >> reporter: but we do know that in griffith park, the 4,000 acre wild land preserve where the l.a. zoo is located, there is only one mountain lion on the loose -- p-22. >> he's an opportunistic animal. if he has an opportunity to have an easy and quick meal, he'll take advantage. >> reporter: not his fault? >> right. >> reporter: part of nature? >> right. >> reporter: but zoo officials aren't taking any chances. moving the remaining koalas under supervised protection. p-22 has never been known to both ear human. if he's guilty at all, it's only for doing what comes naturally. john blackstone, los angeles. the chicago white sox designated hitter adam laroache walked out of spring training

and retired from baseball after a dust-up with management of his son. the 14-year-old was apparently on the field and in the locker room every day. he's walking away from a $13 million contract and considering he only hit .207 last year, he may not get another shot with a different team. jeff glor reports. >> a deep drive, right center field. and it is out of here! >> reporter: for adam laroche -- his sport and his only son have always been inseparable. >> nobody's kid needs to be in a professional locker room. >> i was really unaware of the fact that he was around as much as he was. >> reporter: the 36-year-old abruptly walked away from a $13 million contract on tuesday and the white sox vice president asked him to limit his son's

time in the clubhouse. >> it's not because he was a distraction or wasn't well received or well liked by the players. but in management, sometimes you've got to make some unpopular decisions. >> reporter: 14-year-old drake laroche has been a fixture, alongside his father on the field, and in major league clubhouses for years. complete with his own jersey and personal locker. >> my friends think it's like really cool and everything. but i just think it's normal because i do it every single year since i've been a baby. >> reporter: kids on the field and in the clubhouse isn't uncommon across baseball. but drake's involvement with the white sox was unique. >> you see kids in clubhouses all the time, on a consistent basis. i can't think of a single case where a players' son was in a clubhouse the entire time the player was. >> reporter: the white sox insist their decision had nothing to do with drake's conduct but rather an attempt to focus on winning. >> it's awesome. i'm so lucky to take him to

work. my brothers and i just grew up around the stadium. we always did it, so it's cool to give him the same memories. >> reporter: baseball has long been a family affair for the laroches. adam's dad pitched in the majors for 14 years. family, friends and fans are remembering the life of frank sinatra, jr. he died of a heart attack at a florida hospital. he was 72 years old. the only son of the legendary entertainer, he was a singer himself. but he lived and performed in the long shadow of his father. don dahler looks back. >> maybe you might remember this song, dad. ♪ >> reporter: if frank sinatra was the chairman of the board -- ♪ -- his son, frank sinatra, jr., was the heir apparent. ♪ their relationship appeared as heart felt.

♪ but the road wasn't always so silky smooth. >> for the third night of anguish ended at 3:00 this morning. >> reporter: frank sinatra jr. was kidnapped when he was 19. his father paid the $240,000 ransom. >> his first words when he saw me was "i'm sorry." >> reporter: frank sinatra, jr. pursued his own musical career, but had difficulty finding his own persona. >> for a guy that has to live in the shadow of one of the most important, iconic singers, performers, artists of all-time, those are big shoes to fill. >> reporter: turning to television, he played himself on "the sopranos" and "family guy." but it was only towards the end of his career that he embraced his father's legacy. >> he would introduce me to the audience. he said my son, frank, is

conducting. he said he's almost as good as lawrence welk. choose to move freely. move free ultra has triple-action support for your joints, cartilage and bones in one tiny pill. move free ultra. get your move on. and now try move free night. the first and only 2-in-1 joint and sleep supplement. in our house, imagination runs wild. but at my table, i keep the food real. like country crock's recipe made with real simple ingredients. and no artificial flavors or preservatives. real country fresh taste from real ingredients. welcome to crock country.

you may be one of those people who never forgets a face. even if it's someone you met only briefly years ago. but for some people, it's exactly the opposite. they can't remember any faces. they can't recognize their own parents or each their own children. it's a condition called face blindness. lesley stahl reports for "60 minutes." >> reporter: jacob is one of them. he's 31 years old. he has a college degree, has had great jobs, and he seals p s great jobs, and he seals peems perfectly normal. but just don't ask him to identify any faces. even very famous ones. >> no idea. >> reporter: we showed jacob faces without hair.

a pure test of facial recognition. >> no. nope. can't say if i've ever seen that person. >> reporter: he's seen jimmy carter plenty of times. and knows michael jordan, too. >> oh, lord. >> reporter: he just can't recognize their faces. >> that's just impossible. >> reporter: can you describe my face? you're staring right at it. >> high cheekbones, light eyes. >> reporter: clearly he could see my face, but he says if we happened to run into each other in a few days, he wouldn't know me from any other woman. >> they meet somebody, they have a good time, and a week later they walk past them. >> reporter: brad duchenne has been studying face blindness for 15 years. he said the hardest thing to understand is how someone can see a familiar face with you not

recognize it. so he created a demonstration to give me a taste. faces turned upside down. >> here's some famous faces. you're going to be tempted to twist your head but don't do it. can you identify any of these people? >> reporter: i was completely at a loss. you would think i would know all of these people. >> you've seen them all a lot. >> reporter: i don't know any of these people. i really don't. >> want to see them upright? >> reporter: it was astonishing. with just that click, they became recognizable people before my eyes. i know john travolta. and there was denzel washington, jennifer aniston, sandra bullock. but the one that really got me is the young woman on the lower right, my daughter. i didn't know my own daughter? >> no. >> reporter: i didn't know my own daughter. >> so there she is. >> reporter: am i getting a feeling for what people with

face blindness have? >> when you look at that, there's a face there. there's a nose, mouth, eyes. but you can't put it together. >> reporter: that's stunning. i feel terrible for them now. >> it's really difficult. >> reporter: and largely unknown. rosa only got its name in the 1940s when a couple of soldiers came back from world war ii with head injuries and couldn't recognize their wife or parents. it took another 50 years for science to discover that people could be born face mind like jacob. and joe livingston, a retired teacher. ben, a software products designer. and meg, a doctor. >> if i were your patient, you had spent a long time with me discussing the problem, i come back the next time. >> no, you walk out to the window and i walk out of the room and i don't know who you are. >> reporter: she relies on

patient charts she told us. but there aren't any of those in ben's office, where lunch in the cafeteria can be tricky. >> sitting down at lunch having a discussion with someone about one of my projects and guy across the table gets up and says that's interesting. when you have that meeting, can you invite me? thanks, see you. who is it? i don't know. i have no idea. >> reporter: is it a memory issue? the face doesn't get filed? so they have to rely on other strategies to identify people. hair, body shape. the way people walk, their voice. even style of dress. but jacob told us that it can all fall apart when someone changes their hair, like a colleague named sylvia who he wouldn't find one day until she started putting her hair in her usual pony tail. >> she put it into the pony tail and once that was in place, that was sylvia.

and then she took her hair back out of that pony tail and she disappeared. >> reporter: to him it was show her face changed into someone else's before his eyes. >> now i'm confronted with the situation that got weird. i knew this person was sylvia, but it didn't feel like sylvia. >> reporter: faces mean so much to us. identity, beauty, character. a place to hang all our memories about a person. faces have captivated artists forever. so it may surprise you to learn that the man who painted these faces, renowned portraitist chuck close, is also face blind. say you had dinner with somebody and saw her the next day -- >> wouldn't remember her. >> reporter: yet he's spent his career painting, well, faces. >> yes.

>> reporter: chuck close has face blindness and he paints faces. >> correct. the reason i think i was driven to it was to, to take images of people that mattered to me and commit them to memory in the best way i can, which is to slow the whole process down, break it down with lots of little memorable pieces. >> reporter: which is exactly how he creates these works. he can't make sense of a whole face, so he works from a photograph with a grid on it. and translates what he sees, square by square, onto his canvas. guess what we've done. >> i don't know. >> reporter: we've put together a quiz for you. we brought some of our famous faces to show him. >> from the chin, i think it's leno. >> reporter: and we're surprised he did pretty darn well. >> from the lips, i think it's tiger woods. >> reporter: you're pretty good. but of course, not perfect. >> i don't have a clue.

>> reporter: that's tom cruise. >> right now, my guts are tied in knots because this very activity is a thing that makes me most nervous. oh, now i have to figure out who this person is. >> you can see the full report in a world that's trying to turn you into someone new... ...one hair color wants to help you keep on being you. nice'n easy. natural-looking color... ...that even in sunlight, doesn't look like hair color... it just looks like you. nice'n easy: color as real as you are.

you're not supposed to flush down the toilet. turns out a lot of people flush them any way, and it's causing big problems. contessa brewer reports. >> reporter: in san antonio, they cheered clearing the clog. the problem starts here, when wipes go from the back of the toilet into it. and 7% of wipes are labeled flushable. new york city estimates it spends $3 million a year just dealing with wipes in the sewer system. >> whatever you flush ends up somewhere. it doesn't just disappear. and the sewage passes through -- >> reporter: commission ervin sent s, paenva showed us the screening process but it doesn't catch everything. >> wipes are getting into our gear, clogging them up and we're not able to process as much waste water as we normally

would. >> reporter: kimberly clark told cbs news, our flushable products are tested to ensure they meet the current u.s. industry guidelines for flushability. the industry has firm criteria. wipes have to break down when flushed. but manufacturer compliance is voluntary. no laws regulate how flushable they are. they blame the nonflushable wipes for the clogs. >> there is no evidence presented by anyone at any time that a guideline compliant wipe flushed has caused any issue anywhere. >> reporter: new york city is not alone. >> our preference is, if you're going to use a wipe, that's fine. put it in the trash. >> reporter: that's the bottom line. contessa brewer, cbs news, new york. from the sewers of new york to the streets, where they're

taking out all the old pay phones and installing wi-fi spots. >> reporter: the goal being 7500 of these kiosks stationed around the city. we can have internet access, high speed wi-fi for your own device, even a 911 emergency button here. but the question is, if more people use public wi-fi, does that put more people at risk to hackers? these aren't your daddy's phone booths. in fact, they're replacing them. colin o'donnell helped design the system. >> you've got the internet, browse the web. >> reporter: and it makes regular phone calls? >> yeah, you can make free phone calls, talk as long as you want anywhere in the u.s. >> reporter: at the nerve center, technicians remotely monitor usage.

designed for the rigors of city life, they've been tested to withstand everything from bad weather to dog pee. other cities have tried and failed at public wi-fi, because of a lack of funding. he says new york city will succeed because it will benefit financially from ads on the kiosk sites. >> one of the beauties of this is that it is going to generate ultimately, potentially hundreds of millions of dollars a year for the city that it wouldn't have otherwise. >> reporter: the biggest issue with public wi-fi at this scale is security. >> the main concern for a lot of people, you go on public wi-fi, you're afraid to be hacked. how can they be ensured this won't happen? >> we're a public network. everybody has to have their own encryption key, so it makes for

a very secure and safe network. >> reporter: meaning every time you go online, the system issues a digital key. but there are ways around encryption. >> the first thing you see is an ad that is a spear phishing attack. >> reporter: we asked this cyber expert to show how easily hackers can set up a fake log-in page. >> they think they're connecting to a kiosk but they're connecting to a malicious site and they don't know what they're going to put in their credit card credentials. >> reporter: the best way to be safe is never use public wi-fi for anything with personal information, credit cards or banks. >> we have to be one step ahead of the next threat. >> reporter: they say they have people monitoring any kind of suspicious online activity 24-7 and do not gather your personal information and sell to a third

party. by the way, if you're wondering, if you live within 150 feet of ,

the smog in london is so bad it's blamed for thousands of deaths each year. now some londoners are fighting back with a tiny new air quality monitor strapped to the back of pigeons. charlie d'agata has the story on britain's pigeon air patrol. >> reporter: these pigeons are nothing special. if anything, they're underachievers. they're raising pigeons currently flying at about 120 feet and the little backpacks weigh less than an ounce. or light as a feather. that is princess, the bird, not the guy. princess and a small flock of friends took flight this morning on a mission to save the world. or mostly to raise awareness about all the air pollution in it. >> the reality is that we are all exposed to really toxic

gases in our everyday lives, just by simply going in the streets, everywhere. >> reporter: seven birds, all females, took wing in today's sortie, two with pollution monitoring backpacks. the others are wing men, or wing women. he says his birds prefer to fly in a flock. >> they like to fly together. they do it for security more than anything. that's just like a horse race, you know, the first across the line they'll go off together. >> reporter: the program is partnered with, you guessed it, twitter. to find out how polluted your neighborhood is, you tweet to the birds and they tweet back. pigeons have a long history of serving on britain's battle fronts. notably in world war ii.

>> a street communication is received and deciphered. >> reporter: even a young queen elizabeth supported the air force. today, london faces another threat. an estimated 10,000 people die prematurely in the capital due to air pollution. and the world health organization estimates that globally, air pollution is to claim for the deaths of 7 million people every year. which makes the work of a few good pigeons with cute little backpacks a bit more pressing than just a mere flight of fancy. this morning, we tweeted princess, that pigeon currently on duty, to find out what pollution levels were like here in west london. moments later, we got the response. pollution is currently high in your area. protect yourself. >> that's the "overnight news" for this friday. for some of you the news continues. for others, check back later for the morning news and "cbs this morning." from the broadcast center in new
