Dangerous epidemic. Zika cases add up in the u. S. Its spreading explosively, they warn. Our dr. Richard besser goes to the heart of ground zero where there are a million cases. Live in brazil. Just dance a swimmer out of water. Olympian Michael Phelps dancing in his speedo with his medals. How his dance helped the home team soar to a big victory. Dance dance dance just dance and good morning, america. Happy friday, okay, could you make a free throw staring at Michael Phelps like that. Curtain of distraction . You never know whos going to be behind that curtain. What a night in politics. Last debate for the republicans before the first votes and donald trump did follow through on that promise. He refused to take center stage, instead he hired a hall just five minutes away, held his own event to raise money for veterans. Actually it was at one point in the evening there were five as you know, three days until the Iowa Caucuses and its your voice, your vote. We have full Team Coverage starting with abcs jonathan morning. Good morning, jon. Robin. From the moment he got in the race back in june, donald trump has dominated the campaign but for one night, the other candidates took center stage without him. Before we get to the issues, lets address the elephant not in the room tonight. Reporter from the start of last nights debate the republican candidates took on that elephant not in the room. Donald trump. Donald trump. Donald trump. Donald. Donald. Reporter they mentioned his time seven times in the first ten minutes with ted cruz mocking the donalds absence. Im a maniac and everyone on this stage is stupid, fat and ugly and, ben, youre a terrible surgeon. Now that weve gotten the donald [ laughter ] reporter but a debate without trump turned mostly tame, a showdown without the spectacle. The candidates instead dove into policy, the first real fireworks coming over immigration reform. Because you used to support a path to citizenship. So did you. But you changed so did you, marco. Throughout this campaign youve been willing to say or do anything in order to get votes. Now you want to trump trump on immigration. The facts are simple. When i ran in texas i told the people of texas if you elect me i will lead the fight against amnesty. I feel like a need a n English Dictionary converter. Ted can change his mind. Marco can change his mind. Reporter hoping to rise in iowa before mondays first in the nation caucus, marco rubio talked tough on Foreign Policy and also took on the democrats. I think Bernie Sanders is a good candidate for president of sweden. Reporter cruz at center stage for the first time failed open by trumps absence. His tangle with the moderators falling flat. Chris, i would note the last four questions have been, rand, please attack ted, marco, please attack ted, chris, please attack ted, jeb, please attack jeb. [ booing ] let me say in this s if. It is a debate, sir. Gosh, if you guys ask one more mean question, i may have to leave the stage. Well, dont worry, im not leaving the stage no matter what you ask me. Reporter trumps presence or nonpresence was felt even after the debate was over, take a look at this photo i shot at almost midnight as i was leaving, these guys dressed as chickens with a milk carton with Donald Trumps donald. You took that picture, jon. Reporter yes, i did, yes. Cant you tell . I cant tell your photography. Jon, did the moderators have to trump decided to show up during the debate . Reporter well, his event was only five minutes away so there was real uncertainty up until the last minute about whether or not he would come and make a surprise appearance. Megyn kelly said that they had two alternative outlines for questions and that she didnt get final word that he was definitely not coming until 15 started. All right. Thank you, jon. Conversations over the course of of fox news. He was just a few minutes away, donald trump, hired his own hall, had his own crowd along with Mike Huckabee a Rick Santorum. Tom llamas has all the details. Reporter george, good morning to you. As you heard in jonathans piece, trump wasnt there but he did take some fire on that stage and he said last night he actually considered showing up to the debate and that fox up to the last minute was trying to get him to go there. The show must go on, and thursday night it did. Have to be honest. I wanted to be about five minutes away. Reporter trump claiming fox news apologized to him, but it wasnt enough to reconsider. Fox has been extremely nice and the last number of hours actually. [ laughter ] and theyve wanted me and they said how about now . They called a few minutes ago. How about now, i said, hasnt it already started. Reporter in a statement fox news saying on thursday chairman roger ailes had three brief conversations with donald trump today about possibly appearing at the debate. And that trump offered to appear at the debate upon the condition that fox news contribute 5 million to his charities. We explained that was not possible and we could not engage in a quid pro quo nor could any money change hands for any reason. We raised over 5 million in one day. Reporter trump still claiming victory. Telling his crowd they raised more than 5 million for veterans. Debate thats going on while everyone is sleeping . Theyre all sleeping. Reporter the gop frontrunner even wrangling Rick Santorum and Mike Huckabee who debated on the undercard stage to join him. You respect for doing this event . Hes raising money for veterans. You know, his decision as to whether or not to go to the debate is a separate issue. Reporter trumps followers, some who braved freezing conditions in iowa to watch his speech on an outdoor monitor say it was the smart play. I thought it was a great idea. That. You know, when these people dont play fairly then why go. You know, lets go out and support the best. Reporter and trump personally donated 1 million. Thats what he said to the event. Tweet. An unbelievable event in iowa with our great veterans. We raised 6 million while the politicians talked. Now, trump says 22 vets organizations will get that money, many here in iowa and one they said they got a call from the Trump Campaign yesterday who said, quote, it will be better than winning the lottery. George. Okay, tom, thanks very much. Lets talk about this more with matthew dowd, our political analyst and cecilia vega covering the hillary campaign. Okay, we cant know for sure what the 30,000 or 40,000 un undecided voters in iowa think but you got to say at first blush it looks like trumps bet paid off. I absolutely think it dfrment part of the reason why it did, as him as the brash starting quarterback doesnt show up for the game, the trash talking backup quarterback fumbled the first few steps which is ted cruz and i think donald trump benefited by what happened on that stage. It was the second one that fell flat. In the course of that debate you had a better picture of ted cruz and i dont think that did well for him. Who did well. I think the interesting thing, others were able to shine and i think rand paul did very well in the course bush had a pretty good night. I think jeb bush had a good first hour had a good night but in the end donald trump didnt show and won. Hillary clinton came in for a lot of fire last night. She had a bunch of attacks. I think we have one ready to go. Her campaign tweeted this image of donald trump out and with it, there you go, they say, she says trying not to throw my remote at the tv is what they were talking about. This plays into her narrative. Shes even gone to the point where she called Bernie Sanders my friend. Shes not talking about him as much on the campaign trail right now going above the fray and looking at republicans and even looking past iowa, i think, into this general pretty tight race but most polls show she has a slight lead and shes moved into a different phase. Whats the plan for the final three days . Cautiously optimistic, she is bringing in the big guns. Well see her on the trail for the very first time with bill and chelsea this week looking well past iowa. They know the race is tight and i do think they realize this could be a loss and not bracing whats the biggest unknown . I think the biggest unknown is turnout. We dont know. Everything about Bernie Sanders victory is dependent on new voters and so is Donald Trumps and depending if those show up it goes in two different directions. Thanks very much. Were going to have full coverage here at abc news this week on sunday morning, gma and world news both live in iowa and all the results live monday night and next saturday the Republican Debate at 8 00 eastern. Robin. A lot coming up. We turn to that other big story weve been following, the zika virus, boston reporting its first case of the disease. Now more than 30 detected in the u. S. And take a look at this map. You see the outbreak originating in south america and moving north. Abcs dr. Richard besser is at ground zero this morning in brazil to answer some important questions. Good morning, rich. Good morning, robin. You know, when you walk around the streets of rio you dont get going on here of such big health concern, but when you talk to pregnant women, you get a very different picture. We came to brazil, the center of the zika epidemic. The government here spraying the streets. We met fabiola already expecting when some said not to get pregnant. She tells me through a translator she knows zika is linked to babies with tiny heads and brains so she is spending her paychecks on insect repel apartment. The level of alarm is extremely high. The World Health Organization said its pulling together an Emergency Response committee saying the zika virus is, quote, spreading explosively. So far in the u. S. , there are more than 30 cases detected in 11 states in the district of columbia. All brought back from travel abroad. Zika is a relatively inconsequential virus for the general population, but if youre a pregnant woman who gets so, rich, if somebody comes back to the u. S. With that virus, is there potential they could spread it to others . Thats a big concern, robin, because if someone is infected and comes back to the United States and is bit by a mosquito, that mosquito can bite other people and be infected so if you come back and have any symptoms, you need to be seen and definitely need to use repellant. A lot of concern about pregnant women and wanting to know how long does the virus stay in the system and could it possibly affect future pregnancies. When they look at similar viruses similar to zika they find once a person has recovered and when their symptoms are gone, the virus is no longer in their body so they dont think future pregnancies will be at any risk at all. We heard a report there is a pregnant woman here in new york city with the virus. Well, you know, thankfully theres no mosquito activity in new york city at this time so she shouldnt be putting other people at risk. But theyre going to monitor her developing baby to see if the baby has been affected and once that baby is born theyll do hearing tests, vision tests to see if the baby was damaged. We dont know how big the risk is to that baby. We hope all goes well for mother and baby. Be safe coming back from brazil. For full coverage you can go to goodmorningamerica. Com on yahoo we move to that deadly shootout in oregon. The fbi released new video showing the roadside confrontation between an antigovernment protester and Law Enforcement that left one of the groups leaders dead and abcs Neal Karlinsky has the latest.

Moments later he can be seen getting out with his hands raised then critically reaching at least twice with ace right hand towards a pocket on the left side of his jacket. We wont show the Moment Police fire, but thats when finicum is shot by oregon state troopers and killed. Investigators say a loaded 9 millimeter handgun was found inside the very pocket finicum appears to reach for. You know there are various versions of what happened, most of them inaccurate and some of them inflammatory. We want to give the public as much information as possible as to what happened that day. Reporter as for the standoff the count is now down to four. Just four armed protesters left inside. Them and hope to wrap all of this up soon, robin. We all hope that. Neal, thank you.
