The storms. Several Chain Reaction crashes. Snow and ice sweeping through. The next system were watching already. The cdc now on the scene tonight. The mystery illness in the heartland. A rare infection. More than three dozen cases. 18 people have died. And breaking news in the erin andrews case. What weve just learned. Good evening. Great to have you with us on a friday night. We begin with the new headline in the o. J. Simpson murder case. The l. A. Police confirming they are testing a knife found on his former estate. Chased by police for hours in the white ford bronco. The weapon never found after two the jury finding o. J. Not guilty. But amid reports this is not consistent with the murders, but its being tested. Matt gutman is in brentwood, california, tonight. Reporter tonight that knife, another tortured twist in the o. J. Simpson case. The lapd today saying the knife was allegedly found by a construction worker on o. J. Simpsons property during in the late 1990s, and are investigating whether it could be connected to the brutal stabbing of his exwife Nicole Brown Simpson and her friend ron goldman in 1994. This individual wanted to turn it over to law enforcement. Reporter the lapd says this knife is now being carefully scanned for possible dna evidence, which could take weeks. The shocking part an lapd officer, now retired, was allegedly handed the knife by a construction worker and held onto it for 18 years. Evidence in the o. J. Simpson case . I certainly hope not. But it certainly is very concerning to us. That a police officer, whether retired or active, would not know to submit and turn in evidence or what is believed to be evidence. Reporter during the trial, the lapd was found to have mishandled evidence and never found the murder weapon, believed to be a small knife that played an outsized role in the 1995 trial. This is a rage killing, and hes using a knife because he is there to settle a personal score, a personal vendetta that he has. Reporter ron goldmans father telling the daily news, i hope they test it, i hope it turns out to be the weapon. It would be one more nail in simpsons coffin. The o. J. Frenzy today trending all day on twitter, erupting as people vs. O. J. Simpson is currently airing on fx. Weve got two victims in brentwood. Its pretty brutal. Reporter also reminding us slowspeed chase through l. A. , and of course that yearlong trial. O. J. Was acquitted of the murder, but was convicted in 2008 in an unrelated case, and is eligible for parole next year. Law enforcement official tell us this could be bogus. Investigators checked into and investigated up to 150 knives. None of them had dna matching simpsons or the victims. David . This knife was discovered nearly 20 years ago. Its just now being tested . That would mean that no matter what they found, they would have a real problem using this for anything substantive. You have a guy giving it to more than a decade. Serious chain of custody problems. And if they were able to find dna on the knife, they cant retry o. J. Simpson. Right, double jeopardy. Trial. And voters in five states weighing in tomorrow. And tonight, the fallout from the fiery Republican Debate filled with person attacks. Just minutes into the debate, donald trump shifting focus to his hands and personal attacks on him. But he was also challenged on his shifting positions. And after the debate, appearing to change positions again. Tom llamas in new orleans.

Dont worry about it, little marco, i will. Lets hear big donald. Dont worry about it, little marco. Gentlemen. You ought to better than this. Reporter today, david asking senator rubio if he regrets dishing out the personal attacks himself. You have young children. Do you regret where this has gone . Look, i regret the way the campaign has become, absolutely, because donald trump, for the last year, has made it one of the most vulgar spectacles in american political history. But do you regret engaging on that level . Look, i think sometimes when someone is as offensive as he is repeatedly, he needs to get a taste of his own medicine. Reporter but amid it all, senator ted cruz casting himself as the adult in the room. Megyn, let me just ask the voters at home, is this the debate you want playing out in the general election . The stakes in this election are too high. Reporter but later, cruz sucked right into the fight. Donald, please, i know its hard not to interrupt. Its not what you said in the oped. Breathe, breathe, breathe. Lying ted. You can do it. You can breathe. I know its hard. I know its hard. But just when theyre done with the yoga, can i answer a question . You cannot i really hope we dont see yoga on this stage. You never know. Reporter tonight, trump facing questions about a major flipflop. Asked why he recently endorsed the idea of visas for highlyskilled foreign workers, even though his Campaign Website says those visas would, quote, decimate women and minorities. Im changing. Im changing. We need highlyskilled people in this country. If we cant do it, we will get them in. You are abandoning the position on your website. Im changing it, and im softening the position because we have to have talented people in this country. Reporter but minutes after the debate ended, another reversal. The Trump Campaign declaring the position on their website, the one trump had just run away from, still stands. Quote, no exceptions. The question is, will any of this inconsistency matter . The establishment is trying to wrestle this nomination away from you. What are you doing to make sure that doesnt happen . Well, look, we have a lot of delegates. And well have a lot more i think after this weekend, and i think probably going into next weekend. Tom llamas, with donald trump after the debate. Tom with us from louisiana now.

I just was speechless. Reporter while some democrats are happy the gop spectacle has drawn attention away from clintons email controversy, theres also cause for concern. Just look at super tuesday. A record 8. 5 million republicans turned out to vote, compared to fewer than 6 million democrats. I have not started on hillary yet. Believe me, i will start soon. Reporter clintons advisers privately acknowledge, trump could be tough to beat. And jon with us live. Right now, the Clinton Campaign telling you, theyre prepared to go oneonone with trump . The clinton team is proceeding with the notion that trump will be the republican nominee. Flawed candidate, they believe he could be much tougher to beat than the polls suggest in a general election.
