Campaign was approaching the gutter with each side raising questions about the others qualifications for the highest office in the land. 12 days before the critical primary, our cbs news tracking poll Shows Hillary clinton, the former new york senator with a tenpoint lead over brooklynborn Bernie Sanders. Heres nancy cordes. I dont believe that she is qualified. Reporter sanders startled democrats with that tough charge last night and repeated it today. Maybe the American People might wonder about your qualification, madam secretary. Reporter clintons allies said that crossed the line. Sanders Senate Colleague crossed the line, tweeting, come on, bernie, not qualifyed . Remember what we all have to do together in november. I dont know why hes saying that, but i will take Bernie Sanders over donald trump and ted cruz any time. Reporter sanders says she started it. You routinely say you respect Hillary Clinton and her experience. So why do you now believe shes unqualified . Because the Washington Post had a headline which said, clinton questions whether sanders is qualified to be president. That was what was thrown at me. Report clinton never actually called him unqualified, though she has stepped up her attacks. Well, i think he hasnt dunn his homework and he has been talking for more than a year about doing things that he obviously hadnt really studied or understood. Reporter the change in tone has to do with the looming new york primary, which suddenly looks like it could be close. To show shes the true new yorker, clinton ditched her motorcade today in favor of the subway. After an early struggle with her fare card, the former first lady rode the rails for nine blocks in the bronx. It is so convenient. It is just the best way to get around. Reporter a loss for clinton in the state she represented would be humiliating, but for sanders, the stakes are even higher. He needs to turn that race around, charlie to, preserve even a narrow path to the nomination. Rose thanks, nancy. Earlier today senator sanders joined us here in our new york newsroom. You said that secretary clinton isnt qualified because she takes super pac money and has supported trade deals. What i said was in response to what she has been saying. Washington post headline, clinton questions whether sanders is qualified to be president. I thought it was appropriate to respond. Rose but is it tit for tat . Is that what this Campaign Conversation ought to be about . No, it certainly should not be. As you may know, i had tried to run an issueoriented campaign, which is what i believe the American People want to hear. They want to hear about what ideas we have to improve their lives, not just attacking each other every day, but what i do have to say, charlie, if we are getting attacked every single day by the clinton campaign, i want them to know, were going to respond in kind, but i hope that we do not. Meaghan rose do you believe secretary clinton is unqualified to be president . Well, does secretary clinton believe that i am unqualified to be president . Rose why cant you say, yes, she has a firstrate resume in terms of a life in public service. Absolutely. Rose and shes one of the most qualified people to run. She has years of experience. Shes extremely intelligent. You know, i have some experience, too. I have a pretty good record in congress as a senator, as mayor. I think i am qualified to be president. So to answer your question youre right. We should not get into this tit for tat. We should be debating the issues facing the American People. All i am saying, people are going to attack us, if theyre going to distort our records, as has been the case time and time again, were going to respond. Rose people are saying the tenor of this campaign has changed and its sounding more and more like the republican campaign. Well, lets not go that far. No. Rose take a listen to this. This is what you said. You said that clinton should apologize for iraq war deaths. Do you really believe. What . Rose for iraqi war deaths. This is after i was asked to apologize for the tragedy in sandy hook. Rose again, tit for tat. It is tit for tat, but im responding to attacks that are being made against me. Rose im asking where the tenor of this campaign is going, and is that going too far to say she bears responsibility for iraqi war deaths . Do i bear responsibility for the tragedy and the horrors of sandy hook . Lets get off of that. Of course she doesnt bear responsibility. She voted for the war in iraq. That was a very bad vote, in my view. Do i hold her accountable, no. Rose do i hear you saying tonight that im embarrassed by these personal attacks taking place and all i have done is respond to attacks, but im embarrassed and theyre giving a tone to this campaign that i dont like, i dont like the fact i have the participate in it and i wish it would stop on both sides in. Yes. Rose are you willing to say that . Yep, i am. Look, charlie, youre looking at a guy who has been in politics for a long time. There are many elections. I have never run a negative ad in my life. In this campaign, as im sure you can appreciate, every other day people are coming up to me and saying, arent you going to attack Hillary Clinton on her emails . Arent you going to attack the Clinton Foundation . And you know how many times ive done that . Zero. Let me finish. You saw me in the debate, right . When i was asked about email, what did i say . Enough of these damn emails. Rose i want to come back to the iraqi thing one second, one more question. You have made a point that she voted for the iraqi war. Other people did, as well, many other people. Yes. Rose do you hold all of them responsible for the deaths . No. Rose then why say it, senator . Thats the question. I am saying it because i was attacked. Rose thats not a reason. I promise you to say, im saying it because they attacked me. I hope you ask senator clinton, am i responsible. Look, im being asked to apologize, you know. Rose come november 2016, if Hillary Clinton is the nominee, you will be supporting her . I think idea of a donald trump or a ted cruz presidency would be an unmitigated disaster for this country. Ly do everything in my power and work as hard as i can to make sure that does not happen. And if secretary clinton is the nominee, i will certainly support her. Rose thank you for coming. Thank you. Always a pleasure. Rose thank you, senator. Senator Bernie Sanders. I will have more of that interview with Bernie Sanders tonight on my pbs program and tomorrow on cbs this morning. The campaign for the republican nomination took on a decidedly new york flavor today. Major garrett has that. Reporter looking for support in brooklyn, Texan Ted Cruz shook hands with hasidic jews outside a matza bakery. Inside. Would you like to make holes in your matza . I would love to make holes in my matzo. Reporter cruz had a ball. He also made news saying he was cosponsoring a bill with senator Chuck Schumer to recover art stolen by the nazis. Its so alive being in new york. Reporter john kasich devoured an italian subin the bronx as he courted the youth vote near fordham youth. Its all about new yorks 95 delegates. Donald trump stands to win most, but cruz and kasich are trying to pick off delegates in congressional districts with small republican populations. Its great to be home. This is home. Its great to be home. Reporter donald trump doesnt need the food photo op, feasting instead on the adoration of more than 10,000 on long island and pounding cruz for criticizing socalled new york values. Ive got this guy standing over there looking at me, talking about new york values with scorn in his face, with hatred, with hatred of new york. Reporter cruz has maintained that new york values are not conservative values, and he says trump fits right in. Oddly enough our friends in the media are very comfortable with the new york liberal who is has supported andrew cuomo and Hillary Clinton and Chuck Schumer for decades. Reporter trump did pick up the support of one prominent new yorker, former new york city may Rudy Giuliani said today he would vote for the billionaire. Trump also settled an intense power struggle within his campaign, giving new hire Paul Manafort control over all convention preparations and trumps new d. C. Campaign headquarters. Charlie, corey lewandowski, trumps embattled campaign manager, will now be limited to traveling with trump and focusing on future primaries. Rose thanks, major. Belgian investigators released new images today of a key suspect in the brussels bombings. They asked the public for help finding him. Its a sign perhaps that their investigation is coming up short. Heres holly williams. Reporter we dont know his name, and his face is a blur, but if hes caught, the man in the hat, as hes now known, could reveal Vital Information about isis cells in europe. The two other men in this Security Camera image blew themselves up in brussels airport, killing 16 people. But the new video shows the third man walking away, and then into the heart of the city. At one point he breaks into a slow jog, but the rest of the time he appears calm. His distinctive jacket disappears in the later videos and police hope that if its discovered, it could help them find him. Hes last seen here nearly two hours after the airport bombings in the schaerbeek neighborhood where a police raid targeted the apartment the three men set off from, finding bombmaking materials and an isis flag. After missing clues that an attack might be imminent, the belgian authorities are under pressure to find the man in the hat. But he could be hiding in plain sight. Salah abdeslam, the suspected logistics man behind the paris attacks in november, was able to hide out in brussels for four months before he was finally captured. Its thought he relied on friends in the neighborhood where he grew up, an area thats now become infamous as a breeding ground for extremists. Intelligence officials across europe are searching for isis recruits, including those with direct links to the attacks in brussels and paris, and, charlie, today in denmark, Police Arrested four people suspected of traveling to syria to join isis.
