Overnight the gop drama starring donald trump taking wild turns. I dont think not showing up at the debate tomorrow night is reporter first trump appearing on the very network whose debate hes boycotting. I was not treated well by fox and i said, you know, how much i have zero respect for megyn kelly. I dont think shes very good at what she does. I think shes highly overrated. In your Christian Faith turning to the bible suggesting trump channel his christian debate instead of hosting his own event at drake university. You know its called an eye for an eye also. You can look at it that way. Thats old testament. No, no, no. Bill, you are taking if youre the christian, the eye for the eye goes out. Heres what it is. Turning the other cheek. Youre taking this much more seriously than i am. Reporter asking trump if hes being too tense tiff. A lot of people thought when you started to that this was a joke, that youre a buffoon. You know it all. But now i dont think they thought i what kind of a statement is that . Reality guy not a nice way of expressing. Reporter overnight another development. In a oneonone debate mano a mano. Reporter the cruz team sending this letter to the Trump Campaign announcing the duel which reads in part, we owe it to the men and women of iowa. So, we have a venue. We have a time all were missing is a candidate. Reporter the Trump Campaign calling this a desperate attempt to gain more publicity and that the Cruz Campaign is failing in iowa. I caught up with cruz after his late night rally. You think donald trump is afraid to debate you personally. Actions speak louder than words. I would welcome him in sioux city saturday night. We have a venue, a town hall and at the end of the day i dont think hes afraid of megyn i dont even think hes afraid of me. I think hes afraid of the people of iowa. Doesnt want to answer their questions or defend his record. Reporter and as for that from that superpac supporting ted cruz if the debate happens between trump and cruz, the Trump Campaign tells me superpac money is dirty money and the superpacs own ted cruz and open to debating but in canada. Thank you. A lot to talk about on the democratic side, as well Bernie Sanders and Hillary Clinton now neck and neck in iowa. A new poll out this morning showing sanders at 45 . Thats within three points of hillary, meaning they are statistically tied. Abcs jon karl has the very latest from des moines. Good morning to you, jon. Reporter good morning, amy. With just four days to go until those Iowa Caucuses, the battle between Hillary Clinton and Bernie Sanders is getting heated and personal. Overnight before an overflow crowd in mason city, iowa, Bernie Sanders took this shot at Hillary Clinton. My opponent is not in iowa tonight. Philadelphia investment firm. Reporter the Clinton Campaign hit back noting that hillary also met with nearly 50 africanamerican ministers from across the country while in philadelphia. Clinton called out sanders for his recent attacks on her high speaking fees. Senator sanders has started to get increasingly personal with his attacks even compared me to dick cheney last week which, you know, is kind of a low blow. Reporter earlier in the day sanders was back in washington traveling to the white house to meet with the man he hopes to the president and i discussed this morning a number of issues. Reporter sanders emerged from the 45minute meeting predicting he can pull off an iowa upset over clinton. If there is a large turnout i think we win. Reporter while president obamas pledged hell remain doing everything she can to embrace him. I dont think president obama gets the credit he deserves. Reporter but there are signs of Bernie Sanders momentum n iowa even at this alley. 60 bernie, 40 hillary right now. Reporter in the final stretch, the Clinton Campaign is hoping for a big boost from bill clinton, in fact, the former president looks like a candidate he has 13 events between now and the caucus. George, that means that bill clinton will actually be doing more Campaign Events in iowa than Hillary Clinton. My goodness. Thats what he loves. Jon karl, stand by. Im here with matt dowd, our political analyst. Yesterday you posed the question on donald trump, would his refusal to go to the debate be seen as a sign of strength or weakness. 24 hours later . His supporters are sticking with him through thick and thin in the course of this. I dont think thats a problem at this point. Its interesting, everybody that opposes donald thinks it was a bad idea. Everybody that supports donald thinks it was a good idea. At a minimum hes owning the news cycle but poses a bit of a and other candidates. No empty podium at the debate tonight but how do the moderators and other candidates stage. This is going to be a fascinating conversation because trump more now than they did if i think ted cruz is more disappointed than fox news that donald trump isnt at the debate because i think ted cruz is now behind donald trump. Ted cruz needs to start worrying about marco rubio. Momentum in iowa. If he isnt careful marco rubio could come up and finish second. You talked about the momentum for Bernie Sanders in iowa right now. But that latest poll out this morning shows Hillary Clinton with a small lead, basically a dead heat, right now in these final days and he had that meeting with president obama yesterday. He pretty much had to do that after seeming to put on the scale for hillary earlier in the week. Yeah, in the timing was interesting bringing him off the Iowa Caucuses but the president had to come out and show he is keeping by his vow that he will be neutral in this race even though clearly the Clinton Campaign believes that if you went into that secret ballot that president obama would be voting for his former secretary of state. Matthew, the Clinton Campaign has to worry about deja vu. Thought they had a lead going into the caucuses eight years ago. If they let Bernie Sanders win iowa he will win New Hampshire and then this race totally resets in a different territory than they ever thought. Matthew dowd and jon karl, to amy.

The action leaving the occupations leadership behind didnt have to happen. We all make choices in life. Sometimes our choices go bad. Reporter the groups supporters claim finicum was murdered while surrendering. They shot lavoy literally murdered him and was ambushed. But an alleged witness in the convoy says thats not what happened. He charged at the law enforcement. He was not on his knees. There was a miscommunication. Reporter this morning investigators here are still sorting it all out and conducting a full investigation.

Across ten states, the World Health Organization is addressing the spreading virus today and joined now by dr. Anthony fauci from the National Institutes of thank you for joining us this morning. Youre calling this a pandemic in progress. Indeed, it is because the outbreak in south america particularly in brazil and the caribbean certainly is expanding at an alarming way and the association and, again, geographically with this birth defect when the virus infects pregnant women although the evidence for that not definitive.
