The cbs overnight news will be right back. [ vocalizing ] [ buzzing ] [ tree crashes ] [ wind howling ] now we will turn for insight to Anthony Salvato cbs director of elections expert on delegate math and all of the rules of the primaries and caucuses. Tomorrow, if donald trump wins florida and ohio, will his nomination be inevitable. He will be all but certain. He wont clinch but a commanding lead in delegates and commanding position to get the rest that he needs. First because the rules now start to change the way that states give out delegates with more winner take all contests, tends to favor the leader and make it harder for trailing candidates look cruz and kasich to catch up. But more than that, trump will also be heading into a map beyond tuesday that should favor him politically. There will be contests in the northeast in the west. Places that are full of the kind of bluecollar, suburban republicans voteding for him already. So the thinking will go if they cant find a way to stop him tomorrow, in places like florida, ohio, hard to see huh they suddenly find a way to stop him at all. What happens tomorrow if trump wins florida, as seems likely now, but loses ohio . Which is possible. It will become much harder for him to win the nomination thats what his opponents, cruz and kasich are hoping for. Slow him down if not to catch him. A glimmer of hop to those who want to see this process go on. Into the spring, maybe into the summer, and to the convention. Anthony salvanto, cbs news director of elections. Thank you.

With russian air cover, assads forces have captured considerable territory from the rebels. A partial ceasefire has reduced, but not eliminated the fighting. The ceasefire does not apply to isis, which still controls about including the city of mosul with nearly 2 million residents which has been cut off from the world since isis took over in 2014. Well, tonight. Holly williams has rare insight into what is happening there. Outside of mosul. She met refugees who risked everything to escape.

He told us three men were caught escaping just a few days ago. And isis hanged them in the street. Theyre a criminal gang cried this man. And we have been surviving on water and bread.

The men told this a plan to fight against isis themselves now theyre free. And to smuggle their wives and children out of mosul as soon as they can. This was just one night on the front line. But what we heard suggested people in mosul are growing increasingly angry with isis. And scott, that could make retaking the city a little easier.

But the campus is in an uproar after the team captain was expelled. Jericka duncan is looking into this. When the yale bulldogs celebrated on sunday they were missing star point guard jack montague. Today his attorney confirmed that in february, montage was expelled. Investigation found montague developed a relationship with a female student which led to consensual sex in 2014. But the fourth time they allegedly had sex that is in dispute. She states she did not consent. Montague says she did. The team had to apologize after appearing to support montague wearing shirts with his nickname. Posters appeared on campus warning the bulldogs to stop supporting rapists. Somebody has to be here.

Bob schieffer covered every president ial election since 1964. None quite like this one. What do you make of it, bob . Scott, i will tell you on the republican side. What we are seeing here is a changing of the guard. If trump wins the nomination for the convention and looks like he probably will it is going to turn the Republican Party on its ear. If it goes to an open convention, it will be a bloody fight that could break the party into two parties. And in either case, Republican Party scott, that we used to know it, will be replaced by something new, exactly what that will be, is uncertain. And that is the scariest part of all, because the one thing that always bodes ill in politics, economics or National Security matters is just that. Do you think trump could win the presidency . He could. Historically, nominees from do poorly when republicans split over civil rights in 64. Nominated barry goldwatt r they want down to historic landslide defeat. When democrats kicked out Party Regulars and nominated George Mcgovern in 72 he lost every state but massachusetts.

Lesley stahl reports for 60 minutes. Reporter the terrorists are able to communicate with impunity. Reporter the head prosecutor of paris. He investigated all the big acts of terrorism here. Including charlie hebdo, the kosher supermarket, and now the november 13 attacks where 130 people were killed. More than 350 wounded. Do you have phones in terrorist attacks that you have not been able to get into . Because of encryption . Yes. Yes. With all these Encryption Software programs we cant penetrate into certain conversations. We are dealing with the gigantic black hole. A dark zone. Things going on. Its not just phones. One of the things he is looking into is a texting app favored by isis called telegram. Which like the new apple iphone offers advanced encryption. How often have you run in and all of your investigations into telegram. Yes, very often. Telegram. We cant penetrate. We cant get into it. Usually people, install telegram on their phone. The inventer of pel gram. Telegram. A young man without a country. Russian born. Wanders in exile. He created telegram so he could communicate in complete secrecy. It has taken off, used by over 100 Million People. But it is also used by terrorists now. Is this a concern for you . Definitely. 100 million users, probably this discussing are only a fraction of a fraction of a fraction of the potential usage. Still we are trying to prevent it. Telegram has become a goto site for isis. They use it to widely disseminate propaganda like this video of the paris attackers training in syria. But isis fighters can also use telegram to send private messages to each other. To covertly plan and coordinate attacks. Is there something on your site. On telegram that allows any messages. Emails to disappear . Vanish . Yes, so in private messages we have this secret chat feature. Which provides you with, Self Destruct timer. Self destruct timer. You could set a specific amount of time. Few second or a minute, or a week, up to which, after which his obsession with secrecy and security stems from his own personal history. Long before telegram, he was known as the Mark Zuckerberg of russia because he built a popular equivalent of facebook. In 2011. When antiputin marches filled moscow streets. The kremlin demanded he take down the organizers sites. And i refused to do that. Publicly. Next day i head down to policemen on my doorstep. Wonder why . They tried to break into my apartment. There was continual pressure on him to hand over users personal data. Culminating in 2014. When under kremlin duress, he was ousted from his own company. How long did you stay in russia after that . Not a single day. O. , then you fled . I feel that i am not welcome thats when he created telegram. And encrypted it, he says, so activists could be assured that no government could ever access their personal data. He managed to leave russia with reported 300 million which he uses to singlehandedly fund telegram, costing him, he says, over a Million Dollars a month. This was something that you created to allow democracy to flourish. To allow, dissidents in russia and other countries to communicate with each other thchblt you find out this terrorist group uses your site for completely different reasons. Yeah, we were horrified. There is an irony there . There its. But you, know there is little you can do. Because the if you allow this tool to be used for good, it, there will always be some people who misuse it. Hit paris on the night of november 13th. Isis used telegram to take credit for the attacks. It was a wakeup call for european authorities. It is the First Time Ever in europe. That we had terrorists rampaging through our streets. First time we had terrorist thousands wearing suicide belts in heavily populated public areas. Reporter as head of europol he organizes information from 600 agencies. He set up a new countertrimerrorism center to coordinate. How much is encryption a problem. Generally in these investigations . In most of them. Across the across the tens of thousand of investigations that europol is supporting on terrorism and crime. 3 4 of them have encryption at the heart of the challenge that what about november 13 attacks specifically. From what we see. Encryption played a role in that part. Thats something that we are digging into much deeper at the moment. Why is it still a mystery. Not so much a mystery. I can share details about a Serious Investigation in public. We know that the ringleader of the attack. 28yearold. Was a wanted fugitive. Who golded authorities by bragging in the on line isis magazine how he alluded them. Shuttling between europe and syria. He liked taking selfies of his exploits, often posting them online. In this gruesome video, he and his friend tie body to the back of a truck, abud in the drivers seat. We used to tow jet skis. Now we tow infidels fighting us. On everybodys radar screen. I mean you are right. Abud, he has been one of the major targets for france and belgium. Counterterrorism for many months. Before paris, abud was suspected of guiding jihadis in attacks in france and belgium. The attempts were all foiled. In one of them. An iphone belonging to one of the jihadis was confiscated. It was not useful in finding abud because the is was encrypted. We have been told. I want to confirm it. That the encrypted phone may have prevented you from getting information about the paris attacks. That is a theory that need to be looked into. To do so we really need to be able to get into that phone. You know, i say, all of these smart phones make justice blind. Because they deprive us of information that can contribute to our investigation. See the full report on our website. Back. It added this other level of clean to it. It just kinda like.

Thankfully stopped it. Pierced the vest a little bit. But enough that all i had was a giant bruise. The first commercially available bullet resistant vest was invented in 1893 by a chicago Catholic Priest named kazamir zagland. Proved his garment worked by having himself shot in front of an audience. Soon, highprofile people around the world bought the silk and steel vest including arch buick france ferdinand of austria. To wear his vest, june 28, 1914, when an assassin shot and killed him igniting world war i. Recent experiments, proved the invention could have stopped that fateful shot. Fortunately for detective levae he didnt forget to put his vest on. I am here because the vest saved my life.

Parts of the south are still under water after the latest round of devastating floods. But it could have been worse. The National Weather service says a pair of new supercomputers gave people a lot more advance warning of what was headed their way. Demarco morgan reports. Last falls flooding from Hurricane Joaquin in the south and the winters monster blizzard in the northeast were predicted early and accurately by the computers. Longer lead time gave people a chance to prepare. We know forecasts save lives. And he is the director of the National Weather service. As we get closer to an event we can make the forecast with greater resolution and more accuracy. So people can see where specifically the storms will affect. One half of the governments 44. 5 million improvement to their forecasting system. Trillions of observations are gathered from weather balloons, satellites and buoys among other things. The Super Computers run models off that data to predict the weather. American model known as gfs, miscalculated the path of super storm sandy in 2012. The hurricane killed 150 people and caused estimated 68 billion sandy was certainly a turning point in the entire enterprise. It really brought attention to the, the super computing capacity that we had prior to sandy versus what other Operational Centers around the world had. Five days before the storm, the european model correctly predicted sandy would slam into the new jersey shoreline. Severe weather expert with new york station, showed me how the predictions varied. This green line, the european model forecast. This is a week away from landfall. American model shows a decidedly different route. Can you shoisw us the storm path . Remember the european model track. Look how the storm performed. Took the hard left hand bank. The landfall. Maybe a 50mile difference or so. In 2015, an employee of the National Weather service, tweeted an apology for that turned out to be a bust. So many people looked at the forecast. Head for the hills. Never have seen an apology. The agency believes the new system will help forecasters get a better handle on short term daily, not just big weather events. Wealth of information coming at us over the next year which lend confidence we will produce a bet forecast. Thats the overnight news for tuesday. For some the news continues.

In tampa we asked betty myrick and marsha craig about that as they headed into the third trump rally. Reporter are either concerned about the demonstrators and hecklers . I am very concerned about them. I think the government, them. Because theyre impeding the ability of donald to get out his message and free speech. Reporter trump does more than shout down his tormenters. Go home to mom. Go home to mommy. Reporter he baits them. Look to punch them in the face, i till you. Reporter last week, one supporters did just that to a protester. From temperature said he may pay the punchers legal fees. Another thing that was notable about todays event in tampa, scott, is that trump security detail was considerably larger. Perhaps twice the size of what it has been at previous rallies.

All cbs cares now we will turn for insight to Anthony Salvato cbs director of elections expert on delegate math and all of the rules of the primaries and caucuses. Tomorrow, if donald trump wins florida and ohio, will his nomination be inevitable. He will be all but certain. He wont clinch but a commanding lead in delegates and commanding position to get the rest that he needs. First because the rules now start to change the way that states give out delegates with more winner take all contests, tends to favor the leader and candidates look cruz and kasich to catch up. But more than that, trump will also be heading into a map beyond tuesday that should favor him politically. There will be contests in the northeast in the west. Places that are full of the kind of bluecollar, suburban republicans voteding for him already. So the thinking will go if they tomorrow, in places like florida, ohio, hard to see huh they suddenly find a way to stop him at all. What happens tomorrow if trump wins florida, as seems likely now, but loses ohio . Which is possible. It will become much harder r him to win the nomination t right. Ats what his opponents, cruz d kasich are hoping for. Ow him down if not to catch him. A glimmer of hop to those who want to see this process go on. Into the spring, maybe into the summer, and to the convention. Anthony salvanto, cbs news director of elections. Thank you. Severe storms including a tornado swept through western ohio today.

And said he is ordering the withdrawal of most russian forces. Since september, russian war planes have pounded opponents of syrias assad dictatorship turning the tide of the 5yearold civil war. With russian air cover, assads forces have captured considerable territory from the rebels. A partial ceasefire has reduced, but not eliminated the the ceasefire does not apply to isis, which still controls about a third of syria and iraq. Including the city of mosul with nearly 2 million residents which has been cut off from the world since isis took over in 2014. Well, tonight. Holly williams has rare insight into what is happening there. Outside of mosul. She met refugees who risked everything to escape. It is close to midnight on the front line just outside mosul. And these kurdish soldiers are hundreds of yards into nomans land. So some one coming . Yes, they are not coming. Reporter theyre not isis fighters. But a man and a teenage girl. The man strips to his underwear to be searched. Guarded by the kurdish soldiers. Who fear he could be a suicide bomber. Death to escape isis. Walking for miles through the night. And theyre finally allowed to cross through a trench. And into safety. And then one by one, come 12 more men. Some of them handing over guns. It is an extraordinary site. Leave mosul after isis began sealing it off. Stopping civilians from fleeing. And banning cell phones. Overcome with relief, these men wanted to tell us why they fled. But begged us to hide their identities. To protect family members, still in mosul. These are torture marks, said this man. It to burn me. His only crime was smoking. Harsh interpretation of islamic law. This man said he saw another mosul resident beheaded after being caught with a cell phone sim card. Would have happened . He told us three men were caught escaping just a few days ago. And isis hanged them in the street. Theyre a criminal gang cried this man. And we have been surviving on water and bread. Is there any sign that isis is getting weaker . When they first came, they were tough, said this man. But now they can see that mosul is turning against them. The men told this a plan to fight against isis themselves now theyre free. And to smuggle their wives and children out of mosul as soon as they can. This was just one night on the front line. But what we heard suggested and scott, that could make retaking the city a little easier. When iraqi forces eventually begin their offensive to recapture mosul. Holly nice to have you here r once where nobody is ooting. Lly williams, thank you very much for a remarkable report. In a first, an american citizen fighting for isis.

But the campus is in an uproar after the team captain was expelled. Jericka duncan is looking into this. When the yale bulldogs celebrated on sunday they were missing star point guard jack montague. Today his attorney confirmed that in february, montage was expelled. An independent yale investigation found montague developed a relationship with a but the fourth time they allegedly had sex that is in dispute. She states she did not consent. Montague says she did. The team had to apologize after appearing to support montague wearing shirts with his nickname. Posters appeared on campus warning the bulldogs to stop supporting rapists. Somebody has to be here. Head coach james jones says his players are trying to stay focused. In a situation like this you have to come in closer. Believe in each other. Fight harder. Fighting Sexual Assault is an ongoing battle at yale. In 2015, a survey fund that more than 16 of yale students reported they had been a victim of Sexual Assault. Mary havelin, executive director of new York City Alliance against Sexual Assault. There has been an increase in forward to report Sexual Assaults at yale. What does that say about the culture there . I actually think it says that we are Getting Better at what we are doing, perhaps. And that students are feeling more comfortable coming forward. The University Says students are not expelled without careful consideration. Scott, montague has the not been Bob Schieffer is next. Bob schieffer covered every president ial election since 1964. None quite like this one. What do you make of it, bob . Scott, i will tell you on the republican side. What we are seeing here is a changing of the guard. If trump wins the nomination for the convention and looks like he probably will it is going to turn the Republican Party on its ear. If it goes to an open convention, it will be a bloody fight that could break the party into two parties. And in either case, Republican Party scott, that we used to know it, will be replaced by something new, exactly what that will be, is uncertain. And that is the scariest part of all, because the one thing that always bodes ill in politics, economics or National Security matters is just that. Do you think trump could win the presidency . Historically, nominees from outside their Party Mainstream do poorly when republicans split over civil rights in 64. Nominated barry goldwatt r they want down to historic landslide defeat. When democrats kicked out Party Regulars and nominated George Mcgovern in 72 he lost every state but massachusetts. Under the old rule, scott, what this is coming down to is basically a couple of very flawed candidates. Under the old rules. But in todays politics who knows what that means or where this is going. I certainly dont. Bob schieffer, thank you for the insight. Alexander hamilton showed up at we will have that story next. President obama welcomed Alexander Hamilton to the white house today.

It is an extraordinary sight. Very few people have managed to leave mosul after isis began sealing it off. Stopping civilians from fleeing. And banning cell phones. Overcome with relief, these men but begged us to hide their identities to protect family members still living in mosul. These are torture marks said this man. They heated wire and used it to burn me. His only crime was smoking. Illegal under isis. And its harsh interpretation of islamic law. This man said he saw another mosul resident beheaded after being caught with a cell phone sim card.

Anyone insulting anybody. The stakes tomorrow were highest for marco rubio trailing trump in home state of florida. He also called for unity. Make a powerful statement to the country. That is that the Republican Party is not going to allow itself to be hijacked by make conservatives and people who go around dividing us against each other. Republican establishment has not found a way to slow trumps momentum. Paul ryan who said he would work with trump if he is the nominee said in a raidio interview said that it was unacceptable and amed trump for some unrest. Candidates need to take sponsibility. Ere is never an excuse for promoting violence or a culture that presupposes it. Ryan like republicans wary of trump said republican voter anger is real. But warned against adding fuel to the fire. Ohio may show the nation just how hot that fire burns and whether it can be cooled or contained. Major garrett, cbs news. Sanders is confident he will close the delegate gap on clinton today.

Snapchat, google and twitter are making services more difficult for the government to hack. Law enforcement officials around the world insist security should take precedence over privacy. Lesley stahl reports for 60 minutes. Reporter the terrorists are able to communicate with impunity. Reporter france wa molan is the head prosecutor of paris. Of terrorism here. Including charlie hebdo, the kosher supermarket, and now the november 13 attacks where 130 people were killed. More than 350 wounded. Do you have phones in terrorist attacks that you have not been able to get into . Because of encryption . Yes. Yes. With all these Encryption Software programs we cant conversations. We are dealing with the gigantic black hole. A dark zone. There are so many Dangerous Things going on. Its not just phones. One of the things he is looking into is a texting app favored by isis called telegram. Which like the new apple iphone offers advanced encryption. How often have you run in and all of your investigations into telegram. Yes, very often. Telegram. Cant penetrate. Cant get into it. Usually people, install legram on their phone. The inventer of telegram. Young man without a country. Russian born. Wanders in exile. He created telegram so he could communicate in complete secrecy. It has taken off, used by over 100 Million People. But it is also used by terrorists now. Definitely. 100 million users, probably this illegal activity we are discussing are only a fraction of a fraction of a fraction of the potential usage. Still we are trying to prevent it. Telegram has become a goto site for isis. They use it to widely disseminate propaganda like this video of the paris attackers training in syria. But isis fighters can also use telegram to send private messages to each other. To covertly plan and coordinate attacks. Is there something on your site. On telegram that allows any messages. Emails to disappear . Vanish . Yes, so in private messages we have this secret chat feature. Which provides you with, Self Destruct timer. Self destruct timer. You could set a specific amount of time. Few second or a minute, or a week, up to which, after which his obsession with secrecy and security stems from his own personal history. Long before telegram, he was known as the Mark Zuckerberg of russia because he built a popular equivalent of facebook. In 2011. When antiputin marches filled moscow streets. The kremlin demanded he take down the organizers sites. And i refused to do that. Publicly. Next day i head down to policemen on my doorstep. Wonder why . They tried to break into my apartment. There was continual pressure on him to hand over users personal data. Culminating in 2014. When under kremlin duress, he was ousted from his own company. How long did you stay in russia after that . Not a single day. I feel that i am not welcome at that country anymore. Thats when he created telegram. And encrypted it, he says, so activists could be assured that o government could ever access their personal data. He managed to leave russia with reported 300 million which he telegram, costing him, he says, over a Million Dollars a month. This was something that you created to allow democracy to flourish. To allow, dissidents in russia and other countries to communicate with each other then all of a sudden you find out this terrorist group uses your site for completely different reasons. Yeah, we were horrified. There is an irony there . There its. But you, know there is little you can do. Because the if you allow this tool to be used for good, it, there will always be some people just hours after the terrorists hit paris on the night of november 13th. Isis used telegram to take credit for the attacks. It was a wakeup call for european authorities. It is the First Time Ever in europe. That we had terrorists rampaging through our streets. First time we had terrorist thousands wearing suicide belts in heavily populated public areas. Reporter as head of europol he organizes information from 600 agencies. He set up a new Counterterrorism Center to coordinate. How much is encryption a problem. Generally in these vestigations . In most of them. Across the across the tens of thousand of investigations that europol is supporting on the heart of the challenge that Law Enforcement face. What about november 13 attacks specifically. From what we see. Encryption played a role in that part. Thats something that we are digging into much deeper at the moment. Why is it still a mystery. Not so much a mystery. I can share details about a Serious Investigation in public. We know that the ringleader of the attack. 28yearold abdul hamid albaljiki was a wanted fugiive. Who golded authorities by bragging in the on line isis magazine how he alluded them. Shuttling between europe and syria. He liked taking selfies of his ploits, often posting them line. In this gruesome video, he and his friends tie bodies to the back of a truck, abud in the drivers seat. We used to tow jet skis. Now we tow infidels fighting us. What is astonishing is, you knew he was. I mean you are right. Abud, he has been one of the major targets for france and belgium. Counterterrorism for many months. Before paris, abud was suspected of guiding jihadis in attacks in france and belgium. The attempts were all foiled. In one of them, an iphone belonging to one of the jihadis was confiscated. It was not useful in finding abud because the is was encrypted. We have been told and i want to confirm it that the encrypted phone may have prevented you from getting information about the paris attacks. That is a theory that need to be looked into. To do so we really need to be able to get into that phone. You know, i say, all of these smart phones make justice blind. Because they deprive us of information that can contribute to our investigation. See the full report on our website. Back. Irds whistling music introducing new ky touch gel cr me.

The first commercially available bullet resistant vest was invented in 1893 by a chicago Catholic Priest named kazamir zagland. Proved his garment worked by having himself shot in front of an audience. Soon, highprofile people around the world bought the silk and steel vest including arch buick but ferdinand reportedly forgot to wear his vest, june 28, 1914, when an assassin shot and killed him igniting world war i. Recent experiments, proved the invention could have stopped that fateful shot. Fortunately for detective levae he didnt forget to put his vest on. I am here because the vest saved my life.

But it could have been worse. The National Weather service says a pair of new supercomputers gave people a lot more advance warning of what was headed their way. Demarco morgan reports. My god, the truck is sinking. Hurricane joaquin in the south and the winters monster blizzard in the northeast were predicted early and accurately by the computers. Longer lead time gave people a chance to prepare. We know forecasts save lives. And he is the director of the National Weather service. As we get closer to an event we can make the forecast with greater resolution and more accuracy. So people can see where specifically the storms will affect. One half of the governments 44. 5 million improvement to their forecasting system. Trillions of observations are gathered from weather balloons, satellites and buoys among other things. The Super Computers run models off that data to predict the weather. American model known as gfs, miscalculated the path of super storm sandy in 2012. The hurricane killed 150 people and caused estimated 68 billion of damage. Sandy was certainly a turning it really brought attention to the, the super computing capacity that we had prior to sandy versus what other Operational Centers around the world had.

In 2015, an employee of the National Weather service, tweeted an apology for overestimating the snowstorm that turned out to be a bust. So many people looked at the forecast. Head for the hills. Never have seen an apology. The agency believes the new system will help forecasters get a better handle on short term events. Its tuesday, march 15th, 2016. A day in the race for the white house.
