Passing of rene angelil. First the nightline 5. Enough pressure for you . Off. It works fast, liquigels. Youre coming with me. Im gold status dissolves fast to unletter max strength medicine. Lets end this. When cigarette cravings hit relief. Only nicorette mini has a patented formula. Cravings fast. Seconds. Good evening. Were weeks away from the caucus showdown in iowa and the claws manners taking a back seat as candidates slam democrats, attack each other, all fighting for the heart and soul of the republican party. Who scored big . Heres abcs david wright. Reporter tonight donald trump was center stage in every way. Accusing his nearest rival ted cruz of being too canadian. Theres a big question mark on your head. And you cant do that to the party. You really cant. Reporter cruz hit back hard. The constitution hasnt changed. But the poll numbers have. And i recognize i recognize that donald is displayed that his poll numbers are falling in iowa. Reporter now that iowa is less than three weeks away, the gop debate no longer seemed just politely contentious. I have a feeling reporter like the leadup to a rose ceremony on the im probably going home. Reporter now its more like the hunger games. Kill or be killed. Ahead of this debate cruz swore it wouldnt come to this. A lot of folk in the media would love to see donald and me get in a giant food fight. Im not going to engage in that, i hope donald wont either. Reporter but there he was accusing trump of having new york values. Everyone understands that the values in new york city are socially liberal, proabortion, progay marriage, focus around money and the media. Not a lot of conservatives come out of manhattan. Im just saying. Conservatives actually do come out of manhattan, including william f. Buckley and others, just so you understand. And just so if i could, because he insulted a lot of people reporter trump accused cruz of being a canadian. On the campaign trail trump has cruz, who was born in canada, is actually eligible to run for president. He was actually a citizen of canada until 15 months ago, which a lot of people dont understand. And thats a big problem. Reporter cruz was born in calgary, alberta, to a cuban father and American Mother but renounced his Canadian Citizenship in 2014. He insists hes american through and through. Youre one of us, my man. Thats why theyre voting for you. Reporter this new endorsement ad from the duck dynasty patriarch. Our qualifications for president of the united states, is he or she godly . Does he or she love us . Can he or she do the job . Finally, would they kill a duck and put him in a pot and make a good duck gumbo . Ted cruz is my man. He fits the bill. Reporter town halls in iowa, cruz has dismissed the citizenship controversy as a sideshow. I have never breathed a breath of air on this planet i choose him as my Vice President president tial candidate and the democrats sue because we cant take him along for the ride . I dont like that, okay . Donald, you very kindly just a moment ago offered me the vp slot. Ill tell you what. If this all works out im happy to consider naming you as vp. Reporter tonight cruz also took fire on this story, the New York Times breaking cruz and his wife failed to disclose massive loans to his Senate Campaign from Goldman Sachs and citibank. Even as cruz has railed against wall street out on the stump. The federal government has bailed out wall street but somehow seems to abandon main street. Reporter cruz dismissed the times story as a smear. Yes, i made a paperwork error, disclosing it on one piece of paper instead of the other. Reporter jeb bush, who once stood toe to toe with trump, tonight urged him to consider changing his mind on banning muslim immigrants. I hope you reconsider this. That makes it impossible to build the coalition necessary to take out isis. Reporter bush is still among the bestfunded candidates, raising millions from the bush political machine. But support from republican insiders hasnt translated to support in the polls. Tonight trump seemed to take special pleasure in smacking bush down. We dont need a weak person being president of the united states, okay . Because thats what wed get if it were jeb. I tell you what, we dont need that. We dont need that. Reporter his supporters love that about him. The way he takes on anyone who stands in his way. Trump do i agree with what trump says . I certainly do. Reporter trumps supporters delighted this week when he attacked the technicians who did the sound system at his rally. By the way i dont like this mike. Whoever the hell brought this mike system dont [ bleep ] put it in, i tell you. Reporter tonight that trump your comments about banning muslims from entering the country created a firestorm. Is there anything youve heard that makes you want to rethink this position . No. No. Reporter you might think that the democrats watching from home are enjoying all this. But theyre too busy managing their own food fight. The latest polls have Bernie Sanders pulling even with Hillary Clinton in iowa, pulling ahead of her in new hampshire. So the clintons are now in full attack mode. Not just hillary and bill but chelsea too, attacking sanders on health care. Senator sanders wants to dismantle obamacare, dismantle the c. H. I. P. Program, dismantle medicare, dismantle private insurance reporter the Sanders Campaign outraged saying his plan would do nothing of the sort. That is factually incorrect and i hope the Clinton Campaign stops saying that. Bernie sanders is now running a very strong campaign. It looks as though its going to be a very competitive race until the bitter end. Reporter the democrats have it will likely be every bit as contentious as this republican one was. I appreciate your dumping your Research Folder on the debate stage its your record. I will say at least half of the things marco said are flatout false. Reporter the question is did it move the needle for any of the candidates . Donald trump is very happy with his performance tonight. Ted cruz may have some questions. And looking forward to new hampshire, i think christie and rubio are happy with their performances tonight. Reporter well know soon enough. Public 1st february 1st iowa voters will either prove the pollsters wrong or wear them out. David wright for nightline in new york.

Even if its temporary over a long period of time, we dont know what the cumulative effects of that would be. Rise and shine. Nuhuh. Im going to sleep until dinner. It felt like he was a totally different person. I didnt feel like he was my husband anymore. When i watched it i was thinking, what this is guy doing this to himself . Because hes nuts. I get a small glimpse and a new perspective as to the struggles that come from that place that you are in before you you finally understand what its like to be the fat guy . I was in a very, very dark place for most of that 120 days. How are you doing, man . Im doing good. Four months ago j. J. , he was frickin ripped. J. J. Is in the pudgy boys club.

My wife and i are hoping to adopt. Place a kid with us at 400 pounds. You know . I want to be that dad who goes out and goes hiking with his kids. I want my children to be in awe of the man i am. Like i am in awe of the man my dad is. And im not going to do that at 389 pounds. Reporter with basically a food addiction. You think most of this was just what ray was putting into his body . Yeah. Yeah, 80 . All the cliches are true. Its hard work and exercise. And you cannot outwork a bad diet. Reporter with this, a bit of this, a lot of this start off killing it.
