Hillary clinton and Bernie Sanders targeted hispanic voters last night. Nancy cordes is in miami. Good morning. Reporter good morning, so you can see the effect of that upset in michigan here in miami last night. Suddenly, sanders looks like a threat to pick up a couple of states next tuesday and at the very least, slow clintons march to the nomination. So both of them had a reason to go on offense. Excuse me, excuse me. Did you ask reporter the candidates threw down the gauntlet early. I will match my record against yours any day of the week. Well, lets see, lets talk about that. Reporter both came prepared to do battle on immigration. In a debate hosted by univision. I voted for that bill. Senator sanders voted against i. Just imagine where we would be today if we had achieved comprehensive Immigration Reform nine years ago. Children came from honduras and i said, welcome those children into this country. Secretary clinton said, send them back. Reporter emboldened by the narrow michigan win, sanders also took a harder line on clintons paid speeches to wall street firms. That the gentleman who is head of goldman sachs, he didnt give me 225,000 for speaking fees. He said i was dangerous, and hes right. I am dangerous for wall street.

Reporter sanders was put on the spot about this 1985 interview in which he praised cuban leader fidel casro. He educated the kids, gave them health care. Reporter a view many cuban exile dont share. Cuba is an undemocratic country. On the other hand, it would be wrong not to state that in cuba they have made some good advances in health care. I couldnt disagree more. You know, if the values are that you oppress people, you disappear people, you imprison people, even kill people for expressing their opinions, that is not the kind of revolution of values that i ever want to see anywhere. Reporter sanders says when he talks about being a democratic socialist, hes aligning himself with countries like denmark and sweden. Not communist cuba.

Whats clear, hes on the ropes and donald trump, the gop frontrunner, is not letting up. I will be on that ballot on tuesday. Were going to win. I have never discussed dropping out with anyone on my team or anyone on the planet earth. It is not going or anyone oany planet for that matter. Reporter marco rubio desperate to deflate rumors we were dropping out. We worry about the dirty tricks so if anyone calls you and anyone tells you, oh, marco rubio is getting out, you tell them you heard it from me, they are lying to you. Reporter but a meager crowd just outside miami his political base, fueled the impression hes in the twilight of his campaign. Little marco would say i think hes gone. But you never know.

Reporter trump will spend half of his time before the primary outside the sunshine state. An attempt to shore up support for future primaries and clear a path to 1,237 delegates needed to win the nomination. I see probably getting in the delegates. Like the fighter, the ultimate way of doing it. You knock them out. Reporter rubio acknowledged his recent attempts to knock down trump including this infamous dig at the size of his hands you know what they say about men with small hands. I would do it differently. I dont think it reflects good, thats not who i am. Not what by campaign is going to be about. What do you think is rubios demise . I think he tried to be don rickles, frankly.

Sky news had 22,000 documents of real names and phone numbs of the suspected fighters from at least 51 different countries. A man claim tock a disgruntled former isis member passed on the information. The information reveals the identities of more than 1700 jihadis and the isis Registration Form asks 23 questions like, what is your previous fighting experience . What special skills they have and whether they want to be a fighter, commando, or a martyrdom seeker. David martin has more on the fight against isis. David, good morning. Reporter good morning. If this list of isis fighters is confirmed to be authentic, it would be one of the biggest intelligence victories so far in the war against isis. Intelligence can be a powerful weapon perhaps more powerful even than chemical weapons. According to the pentagon isis has mounted a dozen chemical weapon attacks in iraq and syria. This shows the aftermath of the isis strike using a mustard agent in syria last year. But the Chemical Weapons Program may have been dealt a serious blow. A weapons expert was captured last week and he had once worked for saddam husseins regime. The capturing of someone of this high caliber provides a gold mine of information about what isis is doing, how its structured, and in this case its Chemical Weapons Program. Reporter after interrogating him, u. S. Intelligence located a building in mosul where the mustard agent was believed to be manufactured and loaded into artillery shells. British defense minister released this show describing it as an isis weapons factory by destroyed last weekend. The day before that strike, u. S. Aircraft targeted this top commander, known by the alias omar the chechen who the pentagon considered to be the equivalent of the secretary of defense. A Group Monitoring syria said that omar the chechen was seriously injured but not killed. In this case if it turns out he has not been killed its not a strategic impact. What going to weaken isis is an organization is taking back territory from it. Reporter u. S. Intelligence is still trying to confirm whether omar the chechen is alive or dead. Air strikes have killed about 100 isis leaders but whatever intelligence they had died with them. There are only two known cases in which key members of isis had been captured alive and along with their cell phones and laptops milked for what they know. Charlie . David, thanks.
