Norah odonnell is off so jeff glor of cbsn is with us. One of the worlds most dangerous drug traffickers on the loose. Joaquin El Chapo Guzman escaped saturday from mexicos highest security prison. His cartel supplied huge amounts of Illegal Drugs to the United States. He is believed to be responsible for thousands of deaths. Guzman vanished from the shower near his prison cell. Prison officials founldsd a tunnel underneath. He traveled underground nearly a mile before reaching the surface in a construction site. Omar villafranca is franking the search. Good morning. Reporter good morning. A massive manhunt is under way for joaquin El Chapo Guzman. As head of the powerful sinaloa cartel, he was in a turf battle to control lucrative drug routes like this bridge behind me in south texas in order to flood American Cities with Illegal Drugs. This isnt guzmans first prison break, but it is his most sophisticated. It was another elaborate getaway, with one of the worlds most powerful drug lords slipping out of mexicos most secure penitentiary and emerging from a tunnel in this partially built home just one mile away. Mexicos president called it an affront to the mexican state, but said hes confident they can recapture this criminal. Late saturday, joaquin El Chapo Guzman broke out of a super max prison about an hour and a half west of mexico city. Despite threefoot thick walls and a nofly zone he slipped out through a 20 by 20 inch hatch in his cell with a ladder that led to an underground escape route, a nearly milelong tunnel complete with lighting and ventilation. There is no way that chapo guzman could walk away from maximum security incarceration in mexico without the assistance of people on the inside. Reporter guzmans highprofile arrest last year made headlines around the world and was hailed as a major victory in the world against drugs as was told to 60 minutes. In my world it was like winning the super bowl winning the world series. This was the actual trophy. Reporter the trophy, guzman had escaped before in 2001 with help from mexican guards. After his arrest last year authorities dismissed concerns about corruption and denied requests to extradite him to the u. S. Hes locked up in the most reliable prison we have in mexico and certainly once bitten, twice shy. We will take our precautions in this case. Reporter those precautions, clearly not enough. Dozens of prison workers are being questioned about the escape, but now a dangerous drug trafficker may already be back in business. Thousands of people electrocuted beheaded chopping off limbs, throwing people in acid. He committed some ruthless crimes in mexico. Reporter on sunday the u. S. Attorney general vowed to help mexico catch guzman but the damage may already be done. Its believed guzman is back in control of the powerful sinaloa cartel, controlling routes from california all the way to texas. His son also reportedly tweeted out a message, i promise you soon the general will be back. Omar thank you very much. This morning donald trump says el chapos escape backs up his criticism of mexican immigrants and the countrys government. One poll released last week shows trump leading the gop president ial race with 15 of the vote. Former Florida Governor jeb bush and kentucky senator rand paul each had 11 . Trump did not appear last night at the miss usa pageant he cosponsors. Nbc dropped the broadcast after he said mexican immigrants bring drugs and crime to america. Nancy cordes is in washington tracking what trump and other candidates are saying now. Nancy, good morning. Reporter good morning. That pageant aired on a cable channel called reelz instead and the host made no mention of trumps absence. He spent the weekend instead on the campaign trail where he has clearly decided to ignore private pleas from Republican Leaders to dial back his rhetoric. The silent majority is back and were going to take the country back. Reporter in phoenix this weekend, trump revelled in his new front runner status and the crowd of 5,000 revelled right along with him. There and in las vegas he hit illegal immigration hard. And these people reap havoc on our population. Reporter he even weigh ed in on the escape of el chapo warning in a statement he is possibly in the u. S. And his drugs and drug dealers freely cross into the United States through our pathetic border. All the agilation has left trump with little incentive to he had the head of the republican party, reince priebus, who urged him to tone it down but who has been hesitant to chide trump publicly. Mitch mcconnell turned down a chance to criticize trump. House Speaker John Boehner mostly steered clear too. I dont know if hes helping or hurting, but hes a candidate. When you wres well a pig, you both get muddy. Reporter republican strategist doug high says theres a reason Republican Leaders are trying to avoid giving trump too much attention. Not only does it provide more oxygen, but it provides also a narrative of trump versus some establishment, trump versus this person, and it may be a fight that ultimately you cant win, so why get involved in it. Reporter besides, its clear, rejection doesnt faze the donald anyway. Like when i went on dates, if a woman dropped me which happened often i would always like to say or at least in my own mind that i dropped her. Reporter trump is even refusing to rule out a third party run for president if he loses the republican primary. And that could be the biggest headache of all for gop leaders, because if he pulls even 5 of the vote away from the republican candidate he makes it that much harder for a republican to win, charlie. Nancy, thanks. The crowded gop field just added another candidate. Wisconsin Governor Scott walker tweeted minutes ago, im in. Im running for president because americans deserve a leader who will fight and win for them. He will be the 15th republican in the race. There are questions this morning about whether the governor is ready. Dean reynolds is at the Waukesha County expocentre in wisconsin where walker is speaking later today. Good morning. Reporter good morning. The governor will be announcing here later today and he has a reputation as a man who stands on firm conservative principles but it is his record that will be getting a much closer look now. The state budget he signed into law on sunday includes budget cuts that aggravated not only democrats, but also many of his fellow republicans, and yet walker was having none of it. With this budget the taxpayers come first. Reporter the wisconsin governor has never wavered from his view that an aggressive conservatism works if its spelled out to the voters. Voters are serious when they say they want their leaders to take on tough decisions. Reporter the latest quinnipiac poll gives walker an eightpoint lead in iowa where a speech he made in january catapulted him to the first rung of contenders. Im hopeful to Work Together with you to help us provide that kind of leadership that is new and fresh and bold and aggressive. Reporter but walkers policies, which helped turn wisconsin into a right to work state, have not delivered the jobs he promised. He later kind of backtracked a bit and said well that was really a goal and it was an ambitious goal. Dont you want to elect somebody whos going to be ambitious. Reporter awkward exchanges like this have raised questions about his readiness for primetime. Are you comfortable with the idea of revolutions . Do you believe in it . Do you accept it . For me im going to punt on that one as well. No really . Thats a question a politician shouldnt be involved in one way or the other. Reporter to guard against criticism that he lacks a certain president ial heft the governor has been undergoing weeks of briefings on global issues, everything from Net Neutrality to isis. Gayle. All right, thank you, dean. European leaders in greece clinched a deal overnight to revolve the greek debt criessis. Greece will get billions of dollars in loans and keep using the single currency. Hall eelolly williams is in athens. Good morning. Reporter good morning. Afternoon a marathon 17hour overnight negotiating session, greece has finally reached a deal to avoid bankruptcy. The amount of the bailout has not yet been finalized, but its thought that greece needs 90 billion to avert financial collapse. Greece was just days away from literally running out of money. Its banks have been shut for two weeks now and withdrawals at cash machines are limited to around 60 a day. Last month greece rejected the demands of its creditors, chiefly germany and france in return for an extended financial bailout. Their terms included tax hikes and public spending cuts which greece says radical left wing Prime Minister described as blackmail. Last week those facing bankruptcy greece was forced to capitulate. This new financial bailout is akin to life support. Greeces economy is still moribund, a quarter of the country is unemployed and the country will be even deeper in debt. Charlie. Thanks. A deal to limit Irans Nuclear program may be in reach this morning. Marathon talks in vienna are focused on the final details. An agreement could be announced within hours. Margaret brennan is in vienna following the talks and the challenges that remain. Margaret, good morning. Reporter good morning. Well, this is the 17th straight day of negotiations and diplomats are really anxious to wrap them up. Tonight at midnight the temporary freeze on irans existing Nuclear Program will expire and that means the clock is ticking. There was a sense of heavy anticipation in vienna today as a deal with iran finally seemed possible. All weekend secretary kerry shuttled back and forth to meetings with the iranians and even snuck in time to pray at a historic 12th century church. Reza marashi said a deal is very close. I would put it at 99 . I leave that 1 for the unforeseen complication, but i think if theyre in the process of just drafting and agreeing on words in two different languages, then this is essentially like the banks in 2008, its too big to fail. Reporter irans diplomat javad zarif reviewed the agreement. It now gets approval from people around the world. Hassan rouhani said his team had done Everything Possible to win relief from sanctions that have been choking his countrys economy. But even if the diplomats are successful, there are some in the u. S. Congress that want to block it. Republican senator tom cotton from arkansas a staunch critic told face the nation any deal is a mistake. I think whatever deal comes out this weekend will be dangerous for the United States and dangerous for the world. Reporter but the world is still waiting to see what this final deal looks like. In a strange coincidence, the long delayed trial of jason rezian restarted today in iran the very same day that iran as set for a deadline for a nuclear deal.

There will be many more to come as the probe flies past pluto tomorrow morning at more than 30,000 Miles Per Hour. Elaine quijano of our Digital Network cbsn is here with a look at this first of its kind mission. Reporter good morning. This flyby is a rare feat and new horizons is expected to get within 7800 miles of plutos orbit. Scientists know very little about plutos surface, but a team at the Johns Hopkins university applied physics lab in laurel, maryland will soon find out. Nasas new horizons probe has been flying for more than nine years to get this close to pluto. Its nearly 3 billion miles from earth. New horizons is the size of a piano and is fitted with highly sensitive cameras. Traveling in a region called the kiper dealt, ear first for a spacecraft it will take photos of pluto which is only 1400 miles wide about half the width of the United States. They really have to thread a cosmic needle. When it gets to pluto to make all the science work it has to fly through an imaginary box 60 miles by 90 miles on its side and hit that within 100 seconds. Reporter since its launch, new horizons has traveled nearly one million miles every day. To put that distance into perspective, imagine the sun is the size of a quarter placed on the goal line of the football field. Earth would be three miles away. Pluto would stretch 18 yards beyond the far goal line. Before this mission we only knew it as a point of light and a blurry image from the hubble space telescope. Reporter tom has been with nasa since 1965. Theres nothing like seeing essentially a brand new object right in front of your eyes and it was shrouded in a big cloud of mystery before. Reporter new horizons seven instruments will map pluto and its five moons to analyze their surface. This is the last chance to do Something Like this. Its the last body at the very edge of the southeasterly system that were going to be flying by in anybodys lifetime. Reporter when its done with pluto, new horizons will continue its mission, flying past at least one more kiper belt object before heading out into interstellar space. Gayle. Elaine thank you.
