Woodruff european interior ministers pushed through a crisis plan today to relocate 120,000 migrants and refugees. As they did, throngs of people continued pouring across croatia, hungary and austria by rail, road and on foot. Jonathan miller of independent Television News followed their journey today. Reporter we drove from croatia into hungary by remote Border Crossing early this morning and you would have thought they were preparing for war. Overnight hungarys parliament passed a law ordering troops to handle what the Prime Minister is calling muslim invasion. The humvees arrived, the border bristling with military hardware and soldiers. This countrys rightswing leader had pledged to crack down to end the influx and to defend what he called christian culture, but hes being forced by croatia, in less than a week has dumped 30,000 Asylum Seekers on his doorstep to facilitate their transit to the richer uct. Member states to the north. At a hungarian station this afternoon, way up in the northwestern austrian border, 1,300 people disgorminged from a train that had come from the croatian frontier. From the station, theyre shepherded toward austria. As rather friendlier austrian soldiers received the new arrival, reports from brusselss that the bickering between e. U. Member states on where to put people who have arrived in recent weeks had reached fever pitch. For all the exasperation in brussels, for all the political feuding, the bashed comments and the bad blood, even if they do decide on how and where to resettle 120,000 people, it wont make the blindest bit of difference on not only the exodus from the middle east but on where these people end up. Theyre pouring into europe at such a rate that in 20 days time, it will be another 120,000 people. An austrian soldier, a secondgeneration immigrant himself, offered reassurance and instructions in arabic. As they stood waiting, european interior ministers finally voted for their plan for mandatory quotas to farm out the 120,000 refugees. Four former soviet bloc e. U. Member states were overruled. The u. N. Refugee agency has already branded the plan irrelevant to the worst humanitarian crisis in decades. The aim was to allow e. U. Leaders to prevent a united front at their emergency summit tomorrow. Instead deep risks rifts have been exposed as the human surge continues to build. Woodruff the four nations opposing the resettlement plan are the czech republic, hungary, romania and slovakia. Ifill the exiled president of yemen has returned to his country for the First Time Since shiite rebels forced him to flee. President Abed Rabbuh Mansur hadi spent the last six months in saudi arabia.

Commander in afghanistan, general john campbell, said the sexual abuse of young boys by Afghan Forces will not be ignored. He denied that u. S. Troops have been told to look the other way. Ifill the former u. S. Commander in iraq and afghanistan apologized to congress today. Retired army general David Petraeus is serving two years probation for giving classified information to his former biographer and mistress. His testimony at a Senate Hearing was his first since he resigned as c. I. A. Director in 2012. I made a serious mistake, one that brought discredit on me and pain to those closest to me. It was a violation of the trust placed in me and a breach of the values to which id been committed throughout my life. Theres nothing i can do to undo what i did. Ifill the focus of the hearing was u. S. Strategy against Islamic State forces. Petraeus called for beefing up efforts in iraq and syria.

Shed previously declined to state a position publicly. Appearing in des moines, iowa, clinton also called for capping Prescription Drug costs and cutting tax breaks for drug advertising. Too often, socalled new drugs are really old drugs that have just been tweaked a little bit. But then theyre marketed as breakthrough drugs and theyre sold for high prices.

Ifill still to come on the newshour volkswagen admits to rigging 11 million cars. The painful legacy of sexual abuse in the catholic church. The Navy Secretary on women in combat. And why girls struggle to get an education in india. Woodruff the scandal, and the fallout, over volkswagens cheating of emissions standards grew today. Just last week, the e. P. A. Alleged there was deceitful software in a half million cars. Today, volkswagen raised that number significantly and tried to restore customer trust. Woodruff volkswagen revealed that as many as 11 million dieselpowered cars worldwide could be affected by software that was designed to cheat on emissions tests. Most of those cars are thought to be in europe, the automakers primary market. The revelation caused volkswagen stock to plummet for a second day. The company lost almost 19 of its stock value, or 17 billion, monday. The price plunged another 20 during trading in frankfurt today. The c. E. O. Of volkswagen america, michael horn, gave a frank apology last night at an event in brooklyn. Lets be clear about this, our company was dishonest. We have totally screwed up. Woodruff a yearlong investigation by the u. S. Environmental Protection Agency uncovered the software. It switches on a cars emissions controls when a smog test is taking place. But the controls turn off again when the test is over leaving cars emitting up to 40 times the legal pollution limits. The software is installed in volkswagen jettas, beetles, golfs and passats and audi a3s sold in the u. S. Since 2008. The Justice Department has reportedly opened a criminal investigation of the automaker. Investigations are also being launched in france, germany and south korea. Woodruff for more, we turn to john stoll,he is Detroit Bureau chief and Global Automotive editor for the wall street journal. He has been following developments in this story closely. John stoll, welcome. You have been covering this story closely. Youve covered other Auto Industry problems. Where does this one rank . Its up there. I mean, this is one because of the volume of vehicles were talking about and the sort of transatlantic implications, 11 million is not a maul number when you talk about the u. S. Car park. About 85 million vehicles are sold a year. Thats spread over several years of production, but thats a large sum of cars. Volkswagen right now is the biggest automaker in the world as of the first half of 2015. Huge aspiration and obviously in germany theyre big. Woodruff explain exactly what volkswagen did to these cars to make them game this emissions test. Reporter a lot of this was explained in the story you have. The software is known as a masking device. It works when the Compliance Testing is undergone, when thats ongoing. The emissions information says what the test needed to say. So it passes regulatory tests, and then in realworld condition, it emits far more of the harmful admissions into the air than is legally allowed. So its pretty Sophisticated Software that can detect when its being tested and, you know, im sure theres going to be forensics of who exactly designed the software and authorized it and whether or not this is more widespread, but at the moment the e. P. A. Is explicit on how this things works. Woodruff you raise a question. This was something deliberately done by someone. I mean, who had to know . How high up in the company is it thought that this went . You know, i talked to a lot of people about that. Its hard to believe that. Well, i would say that in order to pull this off, the circle could be relatively tight. You know, the pressure is high when it comes to meeting engineering standards. Diesel is a very important part of volkswagens play, not only in europe but in the United States. And they needed to get these cars back on the market about six or seven years ago in order to keep its momentum going. In order to meet that objective, one can imagine that the circle would remain pretty tight and needtoknow basis. Executives who were at the company at the time who have since left said they knew nothing about this and would imagine this originated in germany, but thats speculation. The silver lineing investigateers will probably be able to answer more as far as who, what, when, where, why, but thats in the coming weeks. Woodruff but were hearing 40 times the pollution level is what these cars were emitting. Thats right. As much as that. This is a very harmful emission. Theres in doubt. I think particularly the people who buy volkswagen diesel, and this is a generalization, but they are not only looking for a fuel economy bump, theyre not only looking for a way to save fuel consumption and money, they are buying into the promise that they are reducing emission, that these are safer for the environment, that the promise of clean diesel emissions is actually what they advertise it to be. Thats what makes this so egregious at least on the surface. A lot of people are saying, this ranks up there with some of the most egregious corporate scandals in recent history because of the length of time that the deception went on, and they went up very far in terms of regulatessors in terms of saying they didnt know it was going on. They didnt know why there was a disparity between realworld emissions and testing. Only about a month ago, within the last month, theyve come mean on this issue. Woodruff john stoll, any evidence . What are people saying about whether this could have extended to other diesel manufacturers . Thus far we havent heard from everyone in the diesel market, but thus far a lot of automakers have come out and said theyve done their forensics. Theyve asked the questions of the engineers internally and theyre pretty confident they are not employing the same software. Ill give you a quick for instance. I called General Motors today. They have a lot of diaz ls on the market in europe. They wanted to popularize a smaller car diesel in the United States. They are 100 confident what theyve displayed to regulators is the truth is actually the truth. I think well see more of this roll on, but you Better Believe there are a lot of automakers, regulators and outside researchers looking into that exact question. I think this isnt the last of that story weve heard, but maybe the worst case of it. Woodruff sounds like theres certainly more to be reported on here. John stoll with the wall street journal. Thank you. Ifill its not yet clear what issues pope francis will directly address during his visit here. But one problem casts a long shadow for the Church Sexual Abuse scandals. This pope has pressured top Church Officials to end abuse involving priests. Just this year, the bishops of st. Paulminneapolis and kansas city have resigned in the wake of new revelations. As part of our special coverage of the popes visit this week, special correspondent chris bury reports on how sex abuse by clergy still haunts american catholics. Reporter for the archdiocese of st. Paul and minneapolis, with more than 800,000 catholics, the sex abuse scandal still resonates in a raw and immediate way. I think by anyones definition of a crisis, were in it. I mean, there doesnt seem to be any way out. Reporter for nearly five years, jennifer hassleburger served as the cannon lawyer and expert in church law for the archdiocese, but in 2013, she resigned in protest after, she says, top Church Officials ignored her cautions about a priests behavior. Hassleburger then tipped off authorities and reporters to a sex abuse scandal. I was personally devastated when i learned of the abuse that had taken place on my watch. And if i had been able to do anything about that, then i would have done everything i could, but theres so much opposition to doing anything that would keep people safe that i couldnt be part of it any longer. Reporter in june, her former boss, and another bishop abruptly resigned less than two weeks after the Ramsey County prosecutor dropped this bombshell. And what justice
