[ cheers and applause ] is this the start of her big move . Bernie sanders responds here live. From abc news, a special super tuesday edition of this week. Here now, chief anchor george stephanopoulos. As we come on the air this week, its getting harder and harder to describe the president ial race sounding more and more like a grade school playground. Hillary clinton and donald trump dominating the race. Clinton trounced sanders in South Carolina. And with donald trump ahead right now in nearly all the super tuesday states, marco rubio and ted cruz have unleashed a barrage of new attacks. Trying to slow the trump steam roller. Jon karl is here to start us off. Good morning, jon. Reporter good morning, george. Donald trump is facing his biggest test yet. Insults, attacks, and mockery that looks like it could have been designed by trump himself. A campaign trail saturday donald trump predicting a super tuesday rout. Tennessee. Were going win everything. I think were even i think we have great chance to win texas. Reporter after his doubledigit wins in South Carolina and nevada, some Establishment Republicans finally agree, he could actually win this thing. Trump, hes got the momentum. I think theres a more than 50 chance hes the nominee. Reporter nowhere was that hammered home more than fridays shocking endorsement. We need a first class president. Were going to have it in donald trump. Reporter Chris Christie, who once mocked trump as the entertainer in chief is now in his corner. With trump on the verge of an insuhr mout. Able lead, marco rubio has decided desperate times call for i dont know anything about bankrupting four companies. And you know why . About starting a yufrt thats fake university. Reporter throughout the campaign, rubio insisted he wouldnt go after his fellow republicans. Theres a craving in the media for people the attack each other. Ive never been a campaign that attacks people. Reporter now hes using trumps playbook. Mocking the frontrunner with personal insults. How can a person with the worst spray tan in america attack me on twitter for wearing makeup. He wants to sue me. He should sue whoever did that to his face. Reporter besides the insult assault, rubio has a new label for the bill nar businessman. Hes a con artist. I will never stop before we keep a con man from taking over the party of reagan. H lightweight rubio. Total lightweight. Little mouth on him. Rubio, you saw what happened. He melted. He melted. Reporter the Campaign Turns into a food fight. The question is, is rubios aggressive strategy too little too late. So much at stake, senator Lindsey Graham had a colorful diagnosis for the state of the Republican Party. My party is going bat [ bleep ] crazy. And jon karl yoins us with the rest of the roundtable. I want to start with hugh hewitt. You were there. Lindsey graham, bat bleep crazy . I cant complain about the ferocity or the velocity. This is the business we have chosen. I like covering thing like that. Were on the verge of a tipping point. The Republican Party could split. Christie finance cochair that does not like that he joined up with trump. Split in the Republican Party . I dont know about that. Its entertaining. But its not particularly inspirational by any of the candidates. We all probably shoulden laugh and do laugh at the things that are said. You hear the audience laugh. The Republican Party has to come to terms that theyre not inspiring. Theyre entertaining. And trying to come to terms with donald trump, the real possibility hes the nominee. Absolutely. Im told two dozen House Republicans have told the colleagues they will not support donald trump as the nominee. If he solidifies this on tuesday and goes on to win the nomination, hell be the leader party. Him. All the candidates can say, all the politicians can say, we wont support him. So far, the voters have. Meantime, democratic side, donna, the win for Hillary Clinton. Africanamerican vote. Now, there were three candidates eight years ago. Higher than barack obama. Emp was surprised by the margin, the depth, the excitement she had in South Carolina. Her southern fire wall is in tact. This is a race about delegates, not just winning states. The real question is, will she be able to replicate that in other Southern States like georgia, mississippi . And katrina vanden heuvel. Does Bennie Sanders have a viable path . I think so. Not so fast. Dont write his obituary. 17 states vote in the next two weeks. Whatever happens, he has and i think he has a path. Hes injected new ideas into this campaign. Transformed the the democratic party. Movements. Convention. This goes through may. Hell fight to shape the plat form. Well talk to him ahead. Right now, to senator ted cruz. Hes in arkansas. Good morning, senator. Good morning, george. Good to be with you. Thank you, senator. Looking good in texas. Donald trump strong in so many other super tuesday states. If he wins everywhere else, how can you prevent him from getting the nomination . Chlgt i think super tuesday will be the most important day of the entire primary. It is now. Texas. Were running neck and neck with domd throughout states on super tuesday. If conservatives come out and vote on super tuesday, well have a strong day. 65 of republicans believe that donald trump not the best candidate to go head to head with Hillary Clinton. Donald trump loses to Hillary Clinton. And the only candidate that has had beaten donald trump, that more and more republicans are recognizing donald trump not the right person for us to nominate. If we come together and stand united on super tuesday, well have a good election. Donald trump is winning among conservatives. Among your strong base of e van jell e van vangelical christians. You saw washington dealmakers its washington dealmakers that have gotten us in this mess. Donald promises more deals with democrats. Hes contributed to jimmy carter, john kerry, Hillary Clinton, Chuck Schumer. Hes funded openborder democrats for 40 years. One of the stiking ing striking things. Donald talks about immigration. In the 2013 battle over amnesty. When i was leading the fight amnesty bill, donald trump was funding the gang of eight. Five of the eight members received over there are 50,000 from donald trump. You cant fund open border democrats and say youre going to secure the border and stop illegal immigration. You have made that point about him supporting democrats for weeks. It doesnt seem to be sticking. Why not . Listen, i think were seeing Real Movement in the polls. We won in iowa. I think on super tuesday, well have a good night. It was striking at the debate this week, when donald trump does agreed with me. Number one, on israel. He said america should be neutral between israel and the palestinians. I strongly disagree. If im president , america will stand unapologetically with israel. He said, ted, you have to be willing to cut deals. Compromise. Ill tell the people at home. Im not going to compromise on the bill of rights. Im not going to bargain away your Second Amendment rights and sit down with harry reid or Chuck Schumer and agree on Supreme Court nominees. We need a president who will invest the Political Capital to defend your constitutional liberties. Donald trump told us at the debate, he doesnt intend to do that. Theres a reason when harry reid was asked about the republican field said the republican he likes the best was donald trump, he said, because i can work with him. Hell cut deals. You have made a big issue of Donald Trumps taxes. Now released summaries of your own returns. If he releases those same kind of summary, will that be enough . What about his statement gnat he believes he might be targeted by the irs because hes a christian . Well, i i think his statement. Nobody had any reaction other than laughter. Listen, aye released now nine years of taxes. Any of his Tax Information. He needs to release his Tax Information and the fact that hes refusing to do so really suggests as mitt romney pointed out, there may be a bomb shell in there. Something hes hiding. What you to think it is . A lot of Media Outlets have reported he doesnt make nearly as much money as he says he does. Maybe mitt romney is richer than donald trump . We dont know. But hes clearly hiding something. On the other hand, it could be donations to liberal groups like planned parent hood. At every debate, it seems, hes praising them. Maybe hes written them a bunch of checks. Maybe other issues. There have been multiple media reports about donalds business dealings with the mob, the mafia. Maybe those tax returns show his with the maf wra . Indeed, abc has reported that. Deals with s a concrete, owned by two of the big crime families in new york. We dont know. But the important point is, george in the general election, Hillary Clinton is going to shine a light on all of this. Republican primary voters deserve to know. And the media will amplify the democrat attacks. The primary voters deserve to know, if theres a scandal, if there is, as mid tt romney put it, a bomb shell in Donald Trumps candidates, the voters deserve to know. Republicans are getting nervous and some are calling on you, representative franks, from arizona, urmgs you to join forces. They can yipt and win together or remain apart and each fail separately. For the sake of our country, the conservative cause, and future generations, i adjure them to i agree with the sentiment that to beat donald trump we have to come together. What donald wants is all of us who are convince donald is not the right nominee to be splintered. Divided. Looking at this race, only one kantd has beaten donald trump. Historically, in modern times, no one has won the nomination that hasnt won one of the first three states. Only two of us have done that. Me and domd. If you look at super tuesday. Were the only campaign in a position to beat donald on super tuesday. If youre at home and you dont think donald is the right conditioned. You think nominating him will end up electing Hillary Clinton, even if prapts you like perhaps you like another candidate, i would encourage you to stand with us. The only way to beat donald is to stanld together on super tuesday. Sounds like youre not ready Chris Christie next in a this week exclusive. Janet . Cough if you can hear me.

You heard hugh hewitt read from the meg whitman statement. Your endorsement of donald trump is an astonishing display of political opportunism. I call on christie donors and supporters to reject the governor and donald trump outright. I believe they will. For some of us, principle and country still matter. Well, i love meg whitman. Great friend to me and mary pat. Always has been. We obviously from that statement have a difference of political opinion. Thats okay. Thats what makes this country great. People can have differences of political opinion. Meg has been free to express her views. I honor her. Her. Some supporters said you promised you wouldnt endorse donald trump. Joe mcquaid said you promised him on a phone call. Me called me two days after the primary. I was just told youre about to endorse donald trump. I said, thats absolutely untrue. Im not about to endorse anybody. You didnt say you never would endorse him . I said i would not endorse him then. I said, joe, its two days after the primary. Were taking a deep breath. We havent thought about what were going to do next. During your campaign, you ran teller. You told voters to question mr. Trump. I tell everybody who goes to a donald trump event, if you get to ask a question, just ask him how . First he says hell build a wall across the entire border between the United States and mexico. How . How is he going to make the mexicans pay for the wall . How . They are a sovereign nation. Youre backing him now. Whats the answer . How . Hell have to answer that he will. Campaign. And lets say this. You look at everyone else on the stage, um, and there have not been many more specifics from a lot of other folks on the campaign. There i am, as somebody running for president , making my argument. The wall shiz signature issue. His goto line when e needs applause. You have had the mexican president , two former mexican president s. The mexican minister calls this a racist, ignorant, absurd proposal. You know mexico is not going to pay. What would you expect them to say . How does donald force them to pay . I think this are great ways to use diplomacy and other tools to come to compromise with nations. Well work on those things. Strong leadership is able to talk to folks about what advantages and disadvantages are of certain policies. The fact of the matter is, there wont be question about mr. Trumps strength and his rez resoluteness in terms of getting things done. How . Its the standard you set . It is the standard i set. Hell answer the question. To me, im not answering it. Its the way hell answer it. He hasnt answered it. Hes talk about the trade relationship and working on the trade relationship. He talk about that yesterday and using that as a lever to get them to do things. Its part of a bilateral relationship. Before you were opposed to tariffs. An appropriate conversation between two countries, there are all types of appropriate conversations to have between two countries. Your signature issue was reforming Social Security, medicare, medicaid are essential. Donald trump is the only kantd saying he wont touch Social Security. Heres what you said about that. Mr. Trump, what would you do on Social Security . When i become president , the entire country is going the get so wealthy, so amazingly wealthy and rich, were not going to have to worry about Social Security. How . Again, the question is how . I think we need to do something on Social Security. Ive made that clear. Donald trump and i are not going to agree on every issue. This is the signature issue of your campaign. Its not. The signature issue of my campaign was National Security, keeping america safe and secure from terrorist attacks and making us a better ally and neighbor around the world. Social security is an poernt issue. Ive laid out my views. Ill share them with the candidate. You look up on that stage, no one else has a plan on Social Security. He said thursday night no up with else has plan on Social Security. I have asked all the candidates lots of questions on that issue. At the debate on thursday night, he says the answer of Social Security is eliminating waste, fraud, abuse. In all of your speeches, you said, thats not an answer. We need hard truths. Im not disagreeing what youre saying. So youre disagreeing with donald trump . Im saying hell give more complete answers. Lets hold every candidate to that same standard. The difference in the race is, some members of the media and others want to hold mr. Trump to a different standard than the other ca
