>> thanks for watching, i'm tony harris, in new york city. john siegenthaler is up now. >> thank you tony. donald trump and hillary clinton, each won seven states and many delegates. it happens the democratic party is rallying behind hillary clinton many the same can't be said for the gop. sharply divided over donald trump. senior correspondent michael shure is in miami, michael. >> john, good evening, donald trump can what he had to do, in a way losing texas was a good thing for him because i.t. kept ted cruz in the race. ted cruz would have dropped out if he hadn't bee been able to wn his home state. trying to get the republican

party endorsers that have backed him, the calendar doesn't favor him nor does the result that he saw last night from super tuesday. but the field made thin a little bit tomorrow, the reports having ben carson leaving the race but the night belonged to donald trump. news that ben carson will be leaving the race, will not attend the debate and sees no path forward. super tuesday propelled donald trump further tort towards closg the biggest deal of his life. >> i have millions and pllts. this is nomillions,not like thi. paul ryan, i don't know him

well, if i don't, he's going to have to pay a big price okay? >> got triple the number of delegates in texas than trump did, getting behind him as the only candidate that can defeat trump. >> for the candidates that have not yet won a state, have not racked up significant delegates, i ask you to prayerfully consider us coming together uniting. >> but cruz's sharpest words were for trump. >> in our nation's darkest hours, fzr told us that we have nothing to fear but fear itself. jfk told us to ask not what our country could do for us but to ask what we could do for our country. america shouldn't have a president whose words would make

you embarrassed if your children repeated them. >> tuesday was anything but superfor marco rubio, though he won his first state, minnesota, it was an otherwise crippling night for the be florida senator. he tried to convince supporters in miami that things still look good. >> the pun zits said we're underdogs, i'll accept that. this is a community of underdogs. this is a state of underdogs. this is a country of underdogs but we will win. and when we do, and when we do we will do what needs to be done. >> reporter: as mi misguided s it may seem, rubio counts on florida to reverse his fortunes much as john kasich feels about

ohio. >> i will tell you we can do it. is. >> reporter: the consensus vote saying marco rubio can lose. >> i have been inunsedated with e-mails and calls. from people all across this country joining our effort. >> reporter: the problem for rubio is he has not been inunsedated with votes and the problem with some republicans, after super tuesday, donald trump seems more inevitable. >> if trump there, i will not vote. >> i will do a write-in for marco rubio and resign from the republican party. >> john, many of those people i spoke to, who would they vote for, none of them said hillary clinton john. >> one of the biggest surprises, the 2012 republican nominee mitt romney is trying to get into this. he's giving a speech tomorrow. what is he expected to say?

>> you know the people i spoke to today, said romney is going to be speaking at the university of utah, he will be talking about the race, not running or endorsing, but to remain in the conversation should the convention that the republicans hold in cleveland fall apart with donald trump as the possible nominee, some might think of turning to romney john. >> president of purple strategies is in washington, d.c. tonight. bruce let me stay with mitt romney for a second. the more mitt romney talks, the more he becomes public, doesn't he just help donald trump? >> that's swearnl you might -- serge what you might think, thanks john it's an honor. if the donald trump campaign is feeding off of this anger at the establishment and the perceived failure of washington to really

deliver on promise he just you know is there a bigger better stronger embodiment of the establishment than mitt romney the party's last nominee who actually failed to defeat the democrat and therefore kind of embodies that republican failure to stop the things that are concerning all these trump voters. >> bruce, you told politico, you don't remember anything like this in your memory of the republican party, people have called in tears over trump's rise to stardom lately. >> i think people you heard it just in michael's report john. people are kind of beside themselves because they don't feel they have a good choice. on the one hand if you are a conservative and you care deeply about the things like human rights issue, the second amendment, you don't want hillary clinton the opportunity to put two or three justices on the supreme court and change the trajectory of those issues for 20 years. on the other hand, you see some of this rhetoric coming out of

the trump campaign and coming out of donald trump specifically and his failure to adequately deal with simple questions whether or not you endorse the kkk, it's an impossible choice for a loat of voters and they're really torn. >> for the gop establishment it would seem that super tuesday was a disaster. not only did trump do well but ted cruz a thorn in the side of republicans on capitol hill is the only candidate out there to beat him. what does all this mean for party? >> for those who have been concerned about the rise of ted cruz, i think some of those people in the establishment may now be moving to the space where your enemy of your enemy is your friend. we heard senator linkedi lindsey

home state, and one of the biggest problems that the establishment has, there are two many strategies, keep the candidates in the race, narrow them to one in the race until there is some coalesce eng coale vote. >> bruce you have disenfranchised voters angry, and it almost sounds like the 1960s when conservative barry goldwater emerged as the nominee in 1564. do you see any comparisons here? >> i think there are -- you know nothing is ever exact john. but i think you nailed it. there are comparisons here. think about how our society was changing in the '60s and our economy and the pace of that chain. it was rapid. we're seeing that same kind of lightning pace of change in our

economy, with things like outsourcing and the closing of low-wage manufacturing and textile jobs here in the united states. but also in our culture with the wave of immigration that's come on, with the changes that we've seen on some social issues. and these voters are angry because they have sort of expected the republican party to stand up for their economic interests, for the positions on the social issues, they have abandoned that call if you will and donald trump is their vessel or the fighting back again. >> bruce thanks for seeing you again. be. >> thank you john. >> bernie sanders won 4. he's not about to give up the fight. john terret is in burlington where he's been covering the candidate. john. >> that's right, john, a very,

very cold night in burlington, vermont, the candidate bernie sanders was much loved by the crowd, he loves them. they woke up with a bit of a hangover and they looked at the seven successes that hillary clinton had and the four they had and they realize the numbers don't apparently add up going forward. they met with journalists to say they are still in it to win it and lay out that strategy. tab divine said, yes we are behind and yes, she has a significant advantage but we still think we can get a decent number of pledge delegates by june by concentrating on a state-by-state strategy. they'll win some, lose others. the candidate himself was in maine, that is a state they think they can win. take a listen. >> next sunday i believe at 1:00 the caucuses will be held throughout maine.

we can win here if there's a large voter turnout please vote. thank you all very much! >> reporter: please vote, you heard him say it and the strategy is for example, in florida, they intend to concentrate on elderly issues, a lot of retired people in florida. and then in the midwest where they certainly feel they can do well they're going to go after the secretary regarding trade issues, deals she signed in the past. john. >> it sounds like hillary clinton is focused on donald trump rather than bernie sanders after this big victory. is that the way you see it? >> reporter: yeah, most definitely and i note this when i was in south carolina last week and she had that huge lopsided win in south carolina last saturday. if you remember john she said then, tomorrow, meaning sunday, this campaign goes national. it has been that way since then.

she barely mentions bernie sanders, not mentioning donald trump too often but clearly that's her attack. the javitz center she gave a speech and it was kind of a bush 41 kind of gentler america kind of speech where she tries to distance herself from the aggressive campaign run by donald trump. take a listen. >> we are going to wage a campaign that's about the future anden about bringing us all together. i've said a few times in the last week, it may seem odd to hear this. but i want you to hear it. i honestly believe we need more love and kindness in our country right now. >> one footnote, her campaign manager said the win on super

tuesday, the loss was prohibitive, speaking of bernie sanders, likely to get larger. they reckon they have the calendar and the math on their side. we shall see john. >> based on what's going on in this campaign we're not headed for love and kindness any time soon. john terret, thank you very much. >> a controversial new law that set tough new standards for abortion clinics, also requires doctors have admitting privileges. roxana saberi reports from washington. >> for about 90 minutes the justices grilled attorneys about a controversial texas law and judging from the questions they asked they appear sharply subdivided. outside the supreme court, the debate over one of the biggest abortion cases in years grew loud. >> texas cares about our women. that is what this is all about.

>> this isn't about increasing women's health and safety. it's about putting them in a precarious situation where they don't have access to care. >> reporter: inside the debate grew spirited, conservative justices asked whether a 2008 text law is as damaging to abortion, to have admitting privileges at local hospitals and also requires clinics to meet costly standards similar to emergency rooms. the law's supporters say the goal is to protect women's health. critics say it's caused half the state's clinics to close complicating women's access to the ones that remain. >> there's waiting periods. there's multiple visits that women need to make, they have to get childcare more than once, they have to get time off work, and travel that can be

complicated. >> samuel alito asked. as to some of them: and liberal justice elana kagan queried. colonoscopies, liposuction on and on. scott keller later responded, public concern. the pivotal justice is likely to be thont kennedy. anthony kennedy, but with one justice short due oantonin scalia's death, it could be 4-4. the court's decision is expected to be in late june. if the texas law is held, be

they're a terrorist group connected to terrorist organizations and have planned to disrupt the security of the country and its people. >> reporter: the operation continued into the monk as security forces sealed roads into the area. the crack down follows the arrest of 13 people a week ago in the same neighborhood. they were allegedly linked to the group that was targeted on tuesday. the camp has been home to palestinian refugees for more than six decades. jordan's news agency said authorities broke up a cell connected to i.s.i.l, destabilizing national security. it's impossible to confirm but the targets were said to be government buildings and businesses. >> it's not a place authorities would expect to find i.s.i.l. followers. >> erbiz is just 20 kilometers

from the syrian border and has 120,000 syrian refugees but those involved in the raid were said to be part of jordan. al qaeda in iraq was from jordan. the armed group attacked hotels in the kingdom in 2005. jordan has closed all but two of its border crossings with syria and its only crossing with iraq. there are now almost 20,000 refugees massed at its eastern border with syria. the government need to make sure there are no i.s.i.l. fighters among them. it is a small country with volatile facebook and pockets of support for i.s.i.l. hundreds of young jordanians have gone to syria and the risk of it spreading to here is one of jordan's biggest fears. javier, al jazeera, anan.

weapons. it would rather grow its nuclear program rather than grow its own children. >> with the launch of a satellite may have helped persuade the chinese to disagree to these new extensive measures, the text of the resolution which is almost 20 pages long was discussed in numerous meetings between the u.s. and china. some parts are clearly directed at the north korean leadership, among the luxury groups banned, aquatic recreational vehicles and also snow mobiles. despite the resolution china is still strongly opposed to u.s. plans to deploy a defense missile system known as thad. >> further aggravate the tension on the ground, china opposes the be thad missile system, because

such an action harms the security interests of china and other countries of the region and goes against the goal of maintaining peace, security and stability of the peninsula. >> reporter: there are now two important questions, the provisions of this resolution go further than before, but will it be properly implemented? and how will the north koreans react? in the past when thea been punished by the u.n. security council it's only provoked them to take further action. james bays, al jazeera, at the united nations. >> official say debris from malaysia airlines 370 may have been found. washed up over the weekend in mozambique. only known missing 777. there's a high likelihood the part came from that plane which disappeared in 2014 with 239 people on board. the european union proposing more than $700 million in

improved but the conditions have not improved. the demolition workers are going about their business with some efficiency here, they have cleared at least another 30 minutes, protected by a large number of riot police. there are resistance on the rooftop, six demonstrate eers are at least hoping to delay the demolition of that particular construction but many people are simply giving up and accepting the french government's offer of acceptance of asylum. the application for asylum here in france. that said, there is a number of people for whom the goal of getting to britain remains very strong and they're moving out from the jungle and spreading along the coast to other places such as dunkirk. the camp is about 40 kilometers from the calais jungle, a short hop considering the distance many of these refugees have traveled in the last months. there are no structures allowed

here, only tents and tarpaulins. a decision has been made to try to evacuate this camp too. a census has been made. there's around 1200, 1500 people who are actually at this camp. a new camp is made by medicins sans frontiers, and the camp is going to be closed and that puts more pressure on the refugees who are here, to decide what their future is. many are confused, many are bewildered. many don't know whether to get to the u.k. or to accept asylum here in france. it is a very difficult problem all around. >> paul brennan, reporting. next, can republicans opposed to donald trump still stop him t receiving the nominations. and the issue of the gas leak in california.

this is america tonight.

>> super tuesday was a tough night for the republican establishment. >> in the wake of donald trump's super tuesday romp the republican establishment seems more divided than ever. many view trump as unacceptable and the question for party chair

and gop law makeers is whether trump can be contained by defeating him or influencing him. >> america shouldn't have a president whose words would make you embarrassed if your children repeated them. >> reporter: texas senator ted cruz is urging everybody to join his effort to defeat trump. >> so long as the field remains divided, donald trump's path to the nomination remains more likely. and that would be a disaster for republicans. >> reporter: but with john kasich and marco rubio pledging to stay in through their home state primaries and ohead to head matchup with trump is at least two weeks away. >> and two weeks from tonight right here in florida we are going to send a message loud and clear. >> reporter: by then trump's delegate math may be impossible to stop so a glowing number of

republican senators like party elder orin hatch, in response to an endorsement by former kkk leader david duke, created distance but never mentioned trump by name. >> senate republicans condemn david duke the kkk and his racism. that is not the view of republicans that have been elected to the united states senate. >> reporter: republican how speaker paul ryan took a similar approach avoiding personal antagonism related to trump. >> i'm going to get along great with congress. and paul ryan if i don't, he's going to have to pay a price,

oklahoma? >> reporter: it's the party that could pay the biggest price. many republicans feel with trump as the nominee the republicans could lose control of house and senate, and running away from republican position he on foreign policy, the economy and social programs. >> donald trump they're afraid could destroy the party. the hard place and the rock of destroying the republican party. that's the question. >> reporter: leaving the republican party unsure as trump be movers dmoves close to the rn nomination. mike viqueria. washington. >> donald trump was absolutely super-dominate on supedominant . >> i'm a super-unifier.

if worse i can do is come in second in the two i might not win, that's not person we want to lead the party, right? >> so i mean, does the republican establishment think donald trump is a unifier? >> no, of course, he has had really no experience unifying anyone. and so you know look, there's -- everybody has their own strategy how we can stop donald trump about but last night i think was a clarifying moment. i'll disagree with your characterization. i don't think he had a great night. in a couple of states he was very, very close to losing. he almost lost vermont, almost lost virginia. trump is at 243 and ted cruz is at 220. that's a statistically insignificant difference. if our party doesn't unite behind the strongest possible nontrump candidate before the win are take all states on march

15th, when florida, illinois and ohio vote, if trump wins those win are take all states, he's going to have a mathematically significant lead and it will make it difficult. >> you said he didn't have a good night last night. but this is a guy in many ways the republican establishment laughed at last summer. the new york times published an editorial, saying last summer as trump began to rise in the polls, party stood aside and said let voters decide. now voters are deciding. so why didn't republicans step in sooner? why didn't the chairman of the republican party do that? >> yeah, keep in mind i mean it's not a good practice for the chairman of the national republican party to play favorites in a primary. that it's that's just really not the role.

you have to be the referee. >> but is he the referee now? i mean, it's clear the party establishment is going after trump. >> that's true but i don't think he's doing that. honestly they're going to support whoever the nominee is, they're going to continue to ensure that it's fair fort the candidates -- for the candidates in the primaries and caucus he. you had a few candidates like rick perry and bobby jindal, they knew it would hurt themselves and benefit someone else. that's why it was so significant last thursday on the debate rubio and cruz teamed up. they knew if both attacked trump, neither would be disadvantaged. it's about the prisoners dilemma that occurred. look there's a huge amount of volume of opposition research on trump.

it's time to start unloading it because it's almost too late. the problem was earlier it was too early now it's almost too late. >> giving the mitt romney phenomenon, giving a speech and tweeting, why is he trying to get involved in all there? >> it's a good question, mitt romney is a statesman, he won more votes than anyone in the history of the country except barack obama in 2012, 60 million votes. he doesn't want to see the republican party get destroyed and he sees trump really as the an at thiantithesis. could romney come in and try win a few states and go to the convention? i think that's possible, but i don't think that's what he's trying to do. i think he is going to try discredit trump as much as possible. putting pressure on him to

release his tax returns and refusal to disavow david deuks e and the kkk. it will be interesting to see what he says. >> i have one other question for you. in addition to your consulting duties you're also the vice chair of the travis county gop in texas. >> in austin, yeah. >> last night people elected your new boss, robert morrow who said things about hillary clinton, bill clinton, the form he governor of texas rick perry and i believe he said the bush family ought to be in jail. can you tell me: how does that -- how does it happen that you elect somebody like that, and what are you planning to do about it? >> yeah, look, we had 47,000 votes cast in that race. it was the 24th or 25th race on the ballot. most people didn't know either

candidate. our sitting chairman james dickey was running for reelection and this person robert morrow was also on the ballot. people vote for the name they like or the name that's first. that's what happened. there was a 6,000 vote margin. there are a lot of people surprised or disgusted about this. i've had hundreds of calls trying to remove him from travis county chairman. slanderous comments he's made about rick perry and the clintons, it goes on and on and on. it doesn't say anything about the elects rat or trump or anyone eps e-else. we are going to do everything we can to remove him from office to pressure him to resign to constrain his ability to be chairman for the next two years if he chooses to go forward and if he does choose to go forward we'll start a new organization,

i'll run against him and defeat him two years from now. >> all right matt great to see you. thanks for taking the sometime to talk to us, we really appreciate.. >> thanks john, take care. with super tuesday behind them, the presidential candidates are focused on key states, one of which is ohio, john hendren reports. >> reporter: every serious candidate who has ever been here and will come again -- >> i always love ohio. i love you folks. >> you do have every kind of the be country represented here in ohio. >> rural and urban, wealthy and poor, known for picking presidents. >> now is one of probably dozen battle ground states for presidency, only adozen, out of 50 states there's only about 12 where there's a real contest going on and that's been ohio for years and years and years

and years. demographically it mirrors the country. >> strikely accurate reflection of what happens in the nation whether all the votes are cast. ohio has become the gateway to the white house. since 1964, every single president and that includes johnson, nixon carter, reagan, the elder bush the younger bush and obama have had to win here first. on average the state votes within 1.3 percentage points of the national tally. this year marks a turning point for ohio and the nation. be millennials will match baby boomers. >> we grow up in a tame wher tin there is economic hardships. >> i represent a white male

straight, they cannot afford four years that is republican. >> the reason i believe it should be bernie sanders as president of the united states is consistent 40 years of consistent policies. >> millennials like me are very, very very invested in making slur we protected gay -- sure we protect gay rights and the ability to marry someone you love. >> i'm for donald trump because i want to make america great again and build that wall, donald. >> donald trump is the plan and he's going to make america great again. >> all of the candidates will campaign here aggressively because they know that if their dream of the white house is to become a reality they must win here. john hendren, al jazeera, columbus, ohio. >> now to southern california where porter ranch residents are finally be allowed to go back home. as a methane gas well has spewed

thousands of tons of gas into the air. >> joanie spears has returned to organize what is left in her home. >> reporter: how do you explain this to your kids? >> they're going through a lot. they know that we have to make the right decision for them. and i think they've been preparing themselves to leave. but i think not knowing where we're going and what we're doing it's frightening. >> reporter: spears is not convinced it's safe to live here anymore. the gas company has sealed the well, and the residents started to return last week, her health has deteriorated and now she feels ill again. >> since i came back these past few days i began feeling sick

again. >> since returning to the porter ranch area count officials say they would really like more time for additional air testing including inside homes. >> what is the residual? what is left over in the air? what's left in the atmosphere what's left in people's homes? what is in sediment rock for almost four months? >> the most damaging leak of gas in u.s. history, most people had no idea there were more than 100 wells just over the hills from their homes. the accident prompted protests. >> shut it down. >> reporter: a demand for accountability and lawsuits. >> you know there are many lawsuits, i've heard up to 75. we've got our own lawsuit that we filed on behalf of the people of the state of california. working very closely but city attorney's office. >> reporter: some residents will move past this and resume life in porter ranch.

but spears says she plans to sell this house. >> i think it's one of the most breathtaking places in laxity county. when he saw -- in l.a. county. i couldn't believe i was going to get olook at this every day. i can't believe this could happen in our country. >> reporter: the consolation for people who plan to move? housing prices appear to be holding steady. in fact construction continues on million dollar homes right below the gas storage site. the disaster not a big factor apparently for some buyers though others may think twice. melissa chan. al jazeera, california. >> the math teacher getting dazzling results from his calculus students.

yom, advance placement cls teacher at lincoln high in east los angeles. >> math to many people is complicated. >> i would be one of them. >> yeah, so a lot of the sometimes you just have to sit and you know, try many, many times, and, you know, for a couple of times you may not get it. but with the proper assistance and support you eventually get it. >> his students affectionately call him yom and his students give him high marks for his teaching style. >> he knows we can do well, he always wants us to do lots of practices. i find it very helpful. >> reporter: it was yom's encourage that led one of his students to an extraordinary result on his advanced calculus

placement exam. >> this is a math exam right. over 2,000 students took this exam. one number 12, only 12 students got a perfect score, yom's student frederick was one of them. >> i felt very confident. yom gave us lot of preparation where he would lecture us and give us lessons. also out of school. he did a lot for us. >> yom said doing a perfect score something isn't he's sure he could even achieve. >> to be honest, i don't think i could even get it perfect. i make mistakes a lot of times. >> ironically enough, when he started teaching things didn't add up. >> i was trying to go through

each day. i couldn't even look at the students. i was busy looking at the notes. >> you were nervous? >> i was very nervous. >> instead of quitting yom followed his own advice. kept going until he got it right. >> i understood what their interest was, what their difficulty and what their strength and weakness was. so it was the kids that actually turned me around. >> if you could avoid it you want to avoid it. >> reporter: he's been known to make things fun. want to talk about instantaneous velocity? here is one way. >> ally jumps off hits the water, we are trying to find out when she would hit the water. >> it will a teacher is as much liked as he is feared. >> is yom a gpa killer?

>> that's typically his reputation around school but just because he's well-known to give a rigorous course. however the people that take it like us it's challenging but at the same time over time you kind of grow to it, it becomes really fun and engaging. >> reporter: in case you missed the subtlety of melissa's answer it was yes. >> this is where you get to show me how much you have learned. >> part of the relationship with yom to his kids, he was an immigrant also, landing as a 12-year-old. 20% of the students are english language learners. yom can relate. >> i share a lot of personal stories, i couldn't speak english when i got here. learning math, excelling in one subject actually changed my life. >> we know that he believes in us and we have someone who believes we can do so much better and we're meant for so

much more. >> reporter: and right now, that more is another tough quiz. >> i wish you guys good luck, okay? >> is the gpa killer about to strike again? for these students the answer may well be yes but they will have to keep trying. >> it was like whoa i solved it! >> jennifer london, al jazeera, lincoln heights, california. next up, a milestone in the restoration of the u.s. capital dome. only on al jazeera america.
