all: cbs cares! well today president obama all but endorsed hillary clinton. seven days before the first votes are cast in the race for president. this may be one reason why our new cbs news battleground tracker poll in iowa shows clinton and bernie sanders essentially in a dead heat. here is nancy cordes. >> let's go get them. >> reporter: with a week to go, bernie sanders is trying to emulate president obama's winning formula from eight years ago down to the feel-good ads, and army of young volunteers. >> we are from the bernie sanders campaign. >> reporter: in a pod cast interview with politico, the

president rejected the comparison. >> no, i don't think that is true. >> and gushed about his former secretary of state. saying her skills are being overlooked. >> she has been in the public eye for a long time and in a culture in which new is always better. >> right. >> and -- you know, you are always looking at the bright, shiny object that people don't, haven't seen before. >> reporter: that bright, shiny object has convinced 85% of iowa democrats that he understand how they feel. compared to 65% who say that about clinton. in iowa falls today, kerry aldridge opened to sanders about her struggle to get by. >> i'm waiting for disability to come through. so my parents have to support me. it's just so hard. >> thank you. thank you. >> we are one week away. >> reporter: it is clinton who has won the endorsement of iowa's largest newspaper. she is not a perfect candidate.

"the des moines register" says, but no other candidate can match the depth or breadth of her knowledge or experience. an argument clinton makes at every stop. >> we need a president who understand and can do all parts of the job. >> president obama isn't officially endorsing either candidate. but he made it pretty clear where he stands. calling clinton "wicked smart" and saying "she was a fierce competitor in 2008" who like ginger rogers had to do everything he did just backwards and in heels. >> the old ross perot line from '92. nancy, thank you very much. the race among the republicans nearly as close. our battleground tracker poll shows donald trump ahead of ted cruz, but within the polls margin of error. here is major garrett. >> we're in the final sprint. 172 hours.

>> reporter: ted cruz and donald trump locked in a bitter fight for first in iowa. cruz tried to lighten the mood with a joke about trump's recent erroneous effort to second corinthians as 2 corinthians. >> well, two corinthians walk into a bar. >> reporter: there is nothing light about this ad questioning trump's credentials. >> i'm pro-choice in every respect. >> does this sound conservative. >> i am pro-choice in every respect. >> reporter: trump hid cruz saying he would not support him as the the gop nominee. >> i wouldn't vote for him. i can tell you that. >> reporter: trump reversed course on backing cruz and offered this odd praise of his loyalists. >> i have the most loyal people. did you ever see that? where i could stand in the middle of fifth avenue and shoot somebody. i wouldn't lose any voters, okay, like incredible. >> i will introduce someone who is very near and dear to my heart. >> reporter: iowa, joni ernst appeared with marco rubio. it gave momentum to a campaign vying for a strong third in her

home state. >> she made a promise. i respect that. i was glad she was here to introduce us to the people of iowa. >> rubio supporters, define a strong finish in iowa anything above 15%. scott, that is a figure they argue would separate rubio from bush, christie and kasich and give him a shot at second place in new hampshire. >> major investigate, thanks. another new york billionaire, flirting with the presidential run, former mayor michael bloomberg, democrat turned republican, turned independent. so we will turn to our cbs news political director and anchor of "face the nation" john dickerson. what do we know about bloomberg's plans? >> he is seriously considering jumping into the race. long wanted to run for president. he would run if it looks like it is going to be a general election race between donald trump or ted cruz and bernie

sanders. he believes those representatives of the wings of the two parties would create an appetite for a candidate in the middle who is fiscally conservative and socially liberal. the challenge is to collect the signatures to get on ballot process starts march 1. there may not be a clear signal about either party by that date. >> what are some obstacles? >> he has no party the he has no organization. he would have to build all of that from scratch. democrats and republicans start with a huge lead in electoral college votes in a lot of the states that traditionally vote for those parties. bloomberg would have to compete on a much bigger playing field than democrats or republicans because he starts with no states in his column. and that kind of a campaign would require a brushfire, tended by a charismatic politician who could rouse people and keep them excited for months. that's not the kind of politician he is. he is more known for his policy ideas than his stirring speeches. >> john dickerson, anchor of

face the nation. watching you sunday. thank you, john. late today in houston, a grand jury investigating allegations of wrongdoing by planned parenthood, didn't find any. instead, the jury indicted planned parenthood's accusers. two anti-abortion activists who shot undercover video of planned parenthood employees discussing the sale of aborted fetal tissue for research. the charges include, tampering with a government record, but the da wouldn't say today what that record was. el nino storms leave homes dangling over the pacific. and three inmates make an elaborate escape. the "cbs overnight news" will be right back. ♪

jailers warn the three accused felons should be considered armed and dangerous. investigators say this grainy surveillance video shows the three men on an unguarded area of the roof of the orange county central men's jail. shortly after a 5:00 a.m. friday security check. from there, they were able to rappel down nearly five floors to their escape. >> it appears to be a very sophisticated operation. where they were allowed to go through some security access points. and had some tools that allowed them to do that. >> reporter: jail officials say the inmates cut their way through a steel screen inside their dormitory style cell and made their way into plumbing tunnels. from there the men bypassed three security areas. and gained access to the jail's roof. and used a make shift rope braided to reach the ground. the three men were in county custody facing charges for serious crimes. one was held on $1 million bail for charges including murder.

the obama administration is overhauling the security clearance system used to screen federal workers and contractors. it is opening a new office called the national background investigations bureau which will be designed and run by the pentagon. the overhaul comes after last year's huge data breach where hackers working for a foreign government believed to be china downloaded nearly 22 million personnel files. there is no word on when the new system will come online. meantime, private u.s. companies are also feeling the heat from china's online espionage. lesley stahl reports for "60 minutes." >> they're targeting private companies.

not a fair fight. a private company can't compete against the resources of the second largest economy in the world. >> reporter: the assistant attorney general for cyberattacks and increasingly economic espionage. >> this is a serious threat to our national security. our economy depends on ability to innovate. if there is a dedicated nation state using intelligence apparatus to steal day in, day out what we are frying to develop. >> reporter: what is their ultimate goal, chinese government's ultimate goal? >> they want to develop certain segments of industry and instead of trying to out innovate, outresearch, outdevelop, they are choosing to do it through theft. >> reporter: all you have to do he says is look at the economic plans published periodically by the chinese politboro. they are according to the report, invent ip, in effect blue prints of what industries and what companies will be targeted for theft. >> we see them put out the strategic plan.

then we see actions follow that plan. we see, intrusion after intrusion on u.s. companies. >> do you have of a number of u.s. companies that have been hit? >> it is thousand of actually companies. >> thousand of u.s. companies. >> u.s. companies. >> reporter: getting ceos from the companies to talk is impossible. most have business in china and don't want to be cut of of its huge market. daniel mcgann, head of american super conductor is an exception. his firm spent years and millions developing advanced computer software for wind turbines that mcgann says china looted nearly putting him of business. he is talking because he wants to fight back. >> i am personally never going to give this up. too many lives were affected. too many families were damaged through this. we can never give of on this. >> reporter: you had to fire 600 people. >> yes. >> reporter: out of how many

jobs? >> at the time we were almost 900. >> so how much did you lose in share value? >> total loss is well over $1 billion. >> reporter: today his factory floor is largely silent. a shadow of the once thriving company. >> i think part of the strategy in all of this was to kill us. >> reporter: set out to kill you? >> kill the company. >> reporter: how can he be sure? well his story begins when china passed a clean energy law in 2005 calling for creation of mega wind farms throughout the country. the law made china the hottest wind power market in the world. so mcgann partnered with a small chinese firm, sinovel partly owned by the government. sinovel made skeletons of the turbines and american superconductor, the gadgetry and computer code to run them. they actually built the turbine. >> they make the turbine we make the controls.

>> did they make the turbines with your brains in them? for the entire country of china? >> yes. >> reporter: when he went into business there, china was already notorious for poaching american intellectual property. so he says he did everything he could think of to protect his technology from being stolen. >> we made sure that any software, any, any -- pieces of the code, were restricted and used, to be able to be accessed by a few people within the company. >> reporter: once they got everything over there, couldn't they reverse engineer it? >> we believe that's what nay tried to do. what they learned the encrypted protocol was in the way didn't understand how it worked couldn't reverse engineer it. >> everybody knows if it is on the internet some brilliant hacker can get at it? >> it wasn't accessible through the internet. >> you kept it off the internet? >> yes.

>> it sound look you built a little fortress around your, your precious codes. >> we certainly tried. >> reporter: initially business boomed in china for american superconductor with sales skyrocketing from $50 million a year to nearly half a billion. >> we were going through exponential growth. it is what every technology company wants to get to. is this high level growth. we were there. >> reporter: then in 2011, his engineers were testing the next generation software in china on sinovel's turbines. the software programmed to shut down after the test. but the blade didn't shut down they never stopped spinning. >> so we said why? we didn't really know. the team looks at the turbine and saw running on our hardware a version of software that had not been released yet. >> that's when you realized. >> realized something is wrong. so then we had to figure out how could this have happened. >> reporter: to find out he launched an internal investigation and narrowed it

done to this man, an employee of american superconductor based in austria. he was one of the few people in the company with access to its proprietary software. he also spent a lot of time of in china working with sinovel. >> what they did is they used cold war era spy craft to be able to turn him. >> they turned him. >> and make him into an agent for them. >> do you know any specifics what they offered him? >> offered him women. offered him an apartment, money. a new life. >> reporter: the arrangement included a $1.7 million contract that was spelled out in e-mails and instant messages that mcgann's investigation found on his company computer. in this one, from him to a sinovel executive, he lays out the quid pro quo. all girls need money. i need girls. sinovel needs me. sinovel executives showered him with flattery.

encouragement, you are the "best man like superman." man lake superman." >> did they say we want the source codes? >> all most like a grocery list. can you get us a, can you get us b, can you got us c? >> i have seen one of the messages, text message. in which he says, i will send the full code of course. >> the full code for operating their wind turbine. >> he eventually confessed to authorities in austria. and spent a year in jail. not surprisingly, the chinese authorities refused to investigate. so, daniel mcgann filed suit in civil court in china. suing sinovel for $1.2 billion. he suspected china was still spying on his company. and that beijing had switched from cold war to cutting edge espionage. you can see lesley stahl's full report on our web site. cbsnews.com. the "overnight news" will be right back. ♪ living well your immune system works hard to keep you on top of your game.
