until next time, we'll see you online. welcome to al jazeera america, i'm del walters. these are the stories we are following for you. kathleen sebelius says good-bye to the white house and the affordable care act. federal investigators are trying to determine what caused the collision in california killing 10. an inane -- an ancient scrap

of paper causes quite a stir. kathleen sebelius is now the former health and human services secretary. she resigned last night. and today the participate nominated sylvia matthews burwell to replace her. libby casey is in washington right now, and libby did the secretaries resignation come as a surprise or it is more that shelasted as long as she did that surprised a lot? >> well, there was not a lot of heads up, so it was a surprise. but in retrospect it does make sense because she was there for the entire arc of the affordable care act, but she waited to resign until the open enrollment period ended. she told the president in march that once the law was sort of on its way that she would be stepping down from the post. there was a fair bit of

conflict, especially in the last six months or so because of the self admitted botched rollout of the law and the website problems. so many people wanting to find out if they could get cheaper or health care period were unable to do so in the early rollout. so a lot of people saw her as a sign that went wrong. but today she emphasized all of the accomplishments of being a part of creating this new health care law. >> this was the most meaningful work i have ever been a part of it? and i knew it wouldn't be easy. there's a reason that no earlier president was successful in passing health care reform despite decades of attempts. but throughout the legislative battles, the supreme court

challenge, a contentious reelection and years of votes to turn back the clock, we are making progress. >> this is the largest domestic agency in the government, 70,000 employees, and overseeing things like medicare and medicaid. >> libby this may be the understatement but republicans have been calling for her head for quite sometime so how are they reacting now? >> the top republican in the senate, mitch mcconnell said her resignation is cold comfort for americans who have been disappointed by the law. and a lot of republicans used this opportunity to attack the law that they still call obamacare, and they use this moment to attack the law fresh, we heard from people like ore

win hatch. he reminded people that he thinks the law is an unmitigated disaster, so as we see the republican pushback, president obama chose today to talk about the positive aspects. now he did say there were some bumps that he and the secretary both got some bruises over the last few months and years, really. he said although they have had some setbacks, he put a good spin on her tenure. >> but, under kathleen's leadership, her team at hhs t n turned the corner, got it fixed, not the job done, and the final score speak for itself. >> president obama also talked about the challenges the new head will take on. sylvia matthews burwell will have to go before the senate to get confirmation and go through the hearing process, which will

be a chance for democrats to defending the law and for republicans to attack it. >> it was a college trip that turned into a nightmare, a bus crash killing ten. the crash hand yesterday evening, when a fedex truck hit a bus full of high school students. the drivers are among the dead. the students were headed to a university for a tour. here is what one had to say. >> my head was down and i look up and kind of veer off the road. people say it was a truck driver who was asleep at the wheel, and all of sudden slamming together. there was fire at the front of the bus. it was crushed pretty much. the florida man suspected in a hit and run crash at an day care in florida is now is police custody. robert corchado is accused of

running into that day care center. he surrendered to police after witnesses say he fled the scene and abandoned his car. police say he has a long criminal history involving drugs. his lawyer says he was bullied. that's the latest involving the 16-year-old accused of going on that stabbing spree at a school. authorities say he stabbed more than 20 people with kitchen knives at his high school in suburban pittsburgh. he is facing multiple charges including attempted homicide. being charged as an assault. pope francis is asking forgiveness for child abuse that occurred in the catholic church. pope francis promising to sanction those involved. the apology following an un investigation into abuse last january.

>> reporter: he has already been outspoken on the role of catholic priests who abuse children. but now he has gone further at meeting. >> translator: i feel compelled to personally take on all of the evil which some priests, quite a few in number, obviously not compared to the number of all of the priests, so personally ask for forgiveness for the damage they have done. the church is aware of this damage. it is a personal moral damage made by them. they are men of the church. >> reporter: thousands of cases of abuse by priests have come to light over the past decade around the world. francis directed the vatican to act decisively. but in february a united nations report implied the vatican was still not serious in tackling the problem. he has had policies of moving priests to new parishes had not

ended. >> they placed the preserve accusation of the reputation of the church and the protection of any perpetrators above children's best interests. >> reporter: but some vatican watchers say the church failed to take steps. >> this committee was set up not just to look at the procedures that should be in place for zero tolerance of this evil, but how to look after the kids. the -- the abuse was then, back then, the pain is now. >> reporter: in his last two years as pope, benedict the 16th sacked 400 priests. that's nothing compared to the size of the problem. for many activists the real proof will be more criminal prosecution and financial compensation for victims. in eastern ukraine, prorussian protest ers were

barned to clear out of government buildings, but they are still there. in donetsk they continue to call for a referendum. >> reporter: exhausted minors return to the surface after a tragic shift. below ground the methane gas explosion killed nine of their colleagues. a very real reminder of the risks all here face trying to make a living. >> translator: the quality of life is low here. it was the same with the last government and the government which is now in place. we don't recognize them, and we think that they are going to make it worse. there will be no better life for us here is. >> reporter: coal mining is one of the major industries here in eastern ukraine, and the donetsk mines in particular are regarded as some of the most dangerous in the world. people here have long complained about working conditions and

pay, and some believe giving greater power to those in the region could help improve their lives. politicians wrangled over how to do just that, after a minute of silence for the minors, the interim prime minister promised to give more power to the regions, suggesting a draft bill could be put to parliament. >> i would like to state clearly that the central government is not only ready for dialogue, but ready to fulfill lawful requirements in which all of the citizens in our country in the framework of the changed constitution will be able to satisfy specific requests of every single region. >> reporter: they agreed federallization not an option, but there has been a key demand of pro-russian protesters in donetsk still in a state building, still calling for a referendum. >> translator: in our region, federallization means

independence. firstly economic independence to create conditions for a better life. >> translator: it will be better if we are a federation and we will join russia. if there will be a referendum, we will get more money here. >> reporter: an ultimatum for protesters to clear the building has passed. and now they say everything will be done to avoid force. >> translator: more regional power probably will not increase our quality of life, but it will calm our souls if we know we have power here. >> reporter: the one thing all agree on is many are struggling to make ends meet and now wait for the government to act. crews searching for a missing may slan airline say they are still making progress. the chief marshall says the latest signal heard on thursday probably isn't from the flight

recorders, but they have heard several other signals over the past few days, and australia's prime minister say the crews are close to finding the source. and meanwhile they have held a moment of silence to remember the victims. >> we want to know what transpired in the last minutes before the flight lost contact. of course, we want to know. so that's why we say that we -- we are the investigators, and -- and the experts we will be calling to look into the black box. the united states and south korea launching the largest air defense exercises they have ever done together. it involves more than 100 aircraft and 1400 military personnel. north korea sees the drills as a prelude for invasion.

>> reporter: this is part of an annual exercise between the u.s. and south korea. this year is not as contentious as it was this year, north korea has made similar protests again, but just a few days ago during an exercise, north korea chose that day to hold its own live fire drill. firing about 100 shells in south korean walt -- waters, south korea returning fire. one other issue of note, this is also the day that the south korean defense ministry makes public its interim findings on its investigation into a number of drones that have been discovered in south korea in

recent weeks, something which has dominated media headlines and indeed minds in the mill stair and defense ministry. coming up on al jazeera america, an immigration advocate who is not a citizen, but is trying to change the hearts and minds of those on this hot button issue. we'll hear her story next. clear

imagine being 25 and living your whole life inside the united states, only to be told by the government that you are not an american citizen. well, that's the story ofs a and -- of astrid silver, and she joining us today. you are giving an award for being so courageous, and yet you are blocks away from a congress that doesn't consider you a

citizen. what do you say? >> it's bittersweet to know that not ponl my efforts but so many ores were recognized, and the fight that we will continue to have, and to know that congress is there, and i walked by congress yesterday, and to know it could be as simple as scheduling a vote. >> we pointed out the fact that you have lived here almost your entire life since the age of 4. do you consider yourself to be an american citizen? >> i consider myself to be an american. i --you know, i was raised here. i have all of the values and -- and i have my mexican culture and heritage, and i'm very proud of it, because it is my family and where i came from, but at the same time, america is -- is where i was raised and more importantly, it is -- so many other people that i know that are in my same position that america is the only place i

ever know. i was four. and i have friends that were here since they were 7 months old. >> what will it do to you if the only country that you have known forces do you leave? >> i think it would be devastating. it's something that you don't really want to think about it because it is so daunting to think that at any given moment, right now i have deferred action, which means that for the time being i am okay, thanks to the program by president obama, but my parents could be deported at any moment, and i wouldn't be allowed to visit them. my dad has been here for 25 years as well, and he hasn't been back, and it's a really scary of thinking of going to a country that i didn't have any ties to other than being born

there. >> what do you think about members of congresses and experts that say it is politic that keep it from being passed. what do you say to those members of congress? >> to me it isn't about politics. it's about my family and the families i know that are living this every day. parents are scared to leave their kids at school because immigration officials can come pick them up every time. if congress understood that our stories are -- are not numbers, we aren't just something that you can check off on a box, we are human beings and we have our lives and they are built here in the united states. >> and then there is the white house it says it is for immigration reform yet it is

behind record numbers of deportations. what do you say to them? >> well, just one more thing on the congress members. they have been a little awol on it, and hopefully it doesn't get to the president having to take action. i which the president would implement the policies and make sure the directions would get to ice because immigration customs enforcement is where we're seeing so much of the disconnect with not following up on prosecutor's discretion and not going after people that aren't criminals. >> thank you for fighting for those that can't fight for themselves. we wish you well. >> thank you very much. a reminder on sunday our special series borderland premiers. it is very powerful and talks about why people risk their lives to come to this country.

it will change your mind. well two years ago a document was discovered no bigger than a business card. it had a quote allegedly from jesus suggesting he was married. critics cried foul, but now there is mounting evidence that it is real. >> reporter: it's all about this tiny piece of paper. about 1 and a half by 3 inches. the text in a language spoken in ancient egypt. the keywords are, jesus said to them, my wife. the vatican denounced it as a fake, but now a wide range of scientific testing proves it is an an inchenth document. >> it's a moment for us to reexamine what this really talks

about, and the implications for the church back then and of course the church today. >> reporter: bits and pieces of sentences aren't about to persuade everyone that jesus had a wife. >> this means not conclusively that jesus was married, but it means in the early church that was a subject of conversation, which makes it interesting for us today. >> reporter: thing from -- fragment also says she will be able to be my disciple. >> this talks about women not only as perhaps jesus's wife but also as a disciple. >> reporter: one brown university researcher remains unpersuaded. saying it contains gram

mattedical errors. coming up it will take years to tear down the old bay brimming in san francisco.

welcome back to al jazeera america. i'm del walters. these are your headlines at this hour. the president announcing his choice to replace kathleen sebelius as the secretary of health and human services. kathleen sebelius announcing her resignation last night. the president tapping sylvia matthews burwell to the post. medical -- federal invest gators trying to find out what caused this deadly bus crash in california. ten people were killed. and the pope is asking for forgiveness for child abuse that happened within the catholic church. the pontiff promising to sanction priests who were involved. sometimes out with the old and in with the new is not so

easy. that seems to be the problem in san francisco where they are now taking down the old bay bridge. there are concerns it could collapse and fall on to the new one. >> reporter: disassembling the bay braj is just as hard and maybe harder than building a new one. the demonstration project scheduled to take three to five years is a sprint in engineering terms. >> a westbound section has collapsed into the eastbound section. >> reporter: a section collapsed in the earthquake in 1989, but they are far more worried now. the next three to five years while they take apart this bridge, during that time an earthquake could strike and this bridge could tip over and damage the bridge they just finished

building. being on top of any bridge is scary enough. [ laughter ] >> reporter: this laughter is terror. scientists have been detecting small shakes up and down the coast, and it is certain that in a big shake the old bridge would be terribly dangerous, especially to the new bridge. at the far end that way, the two bridges are no further apart than my arms are outstretched. the old bridge uses a classic design, a long span suspended between two tours. the engineers had to use enormous four-ton jacks to pull back on each of the spans separating them. then cut the span in half. while we were on the deck the crews separated one of the joints, causing the whole structure to vibrate and sway.

i'm terrified because the whole thing is moving, and it's a very scary thing to be in an unsupported bridge like this. first the western most span where it touches are treasure eye land, then rest of the bridge, and then the mud line under the bay. until that point san franciscocans will just hold their breath. i'm dave warren. we are watching the cyclone impacting eastern australia. it is continuing to turn to the southeast and stay close enough to the coast where it is still really not losing much strength

yet. right now that's where the sigh -- cyclone is. equivalent to a category 3 now. not much in the way of severe weather across the united states. that will change, though. thanks are happening here across the southern plains. and this is what the weather map will look like this weekend. warmer temperatures across much of the eastern united states, but here is that sharp contrast. this will bring the warm air up from the south and cold air from the north. and this is where we could see that warm weather developing. the white house now saying it will not allow iran's pick for un ambassador to enter the

country because he is linked to the hostage situation where americans were seized for 144 days. i'm del walters in new york. "techknow" is next. i'm phil torres here to talk about innovations that can change lives. we're going to explore the intersection of hardware and humanity and we're doing it in a unique way. this is a show about science by scientists. hard core in other words: marita davidson, is a scientist, specializing in ecology and evolution. testing a meat substitute that claims to taste like the same thing. >> it does taste like chicken.
