Just over my shoulder and out of sight, an accident just happened here within the last five minutes. Those who did venture out on the roads are making their way home slowly tonight. The roads are already icy, and only expected to get worse in the next few hours. The wintry mix, not just messy, but downright dangerous, as drivers struggle to get traction on the icy roads.

And this is only expected to change over to ice. David . Yeah, very dangerous mix tonight. Linsey, thank you.

Well be tracking this through gma. Thank you. In the meantime tonight, we turn now to the race for 2016, and donald trump late today unleashing on his opponents. On ted cruz, calling him a liar, quote, unstable, a basket case. And trump continued to take aim at jeb bush and now his brother, the former president. George w. Bush and former First Lady Laura Bush joining jeb bush on the trail just moments ago there. Tonight, what trump is now saying about 9 11 and the former president , and also threatening to run as an independent again. Abcs tom llamas in charleston tonight. Reporter tonight, in South Carolina, its big brother to the rescue. Thank you for your hard work for jeb. Thank you for what youre going to do, which is to vote for him on saturday. Reporter former president george w. Bush, right there, posing for pictures, signing autographs. His wife, laura, beside him. A jeb sticker on his lapel. But lying in wait donald trump. His brother is coming into town, which is, of course, lovely. Ever ask yourself why his brother went silent for all these years . No, dont ask yourself that. Reporter trump and the bushes locked in a southern brawl that spilled onto the debate stage. While donald trump was building a reality tv show, my brother was building a Security Apparatus to keep us safe. And im proud of what he did. And hes had the gall to go after my brother the World Trade Center came down during your brothers reign. Remember that. Reporter trump ignoring the boos from the crowd, going even further. They lied. They said there were weapons of mass destruction, there were none. And they knew there were none. There were no weapons of mass destruction. Reporter today, the billionaire amplifying his attacks on the former president. Ive heard for years, he kept the country safe after 9 11. What does that mean, after . What about during 9 11 . I was there. I lost a lot of friends that were killed in that building. The worst attack ever in this country . It was during his presidency. Reporter though trump has mocked jeb bush for bringing his mother to campaign in New Hampshire, hes also accused him of running from the bush name. I asked him about that today. You attacked jeb bush for coming out with the jeb logo and yet no bush name on the campaign logo, and now he has his family im not the first. Im not the first. I said from the beginning i said from the beginning, tom reporter what does that tell you about jeb . I think that the name bush would have been better than an exclamation point. Hes jeb bush. I think he should have used his name. I think it shows that he wasnt proud of the family. Reporter but jeb bush not trumps only target today. His feud with senator ted cruz now exploding. Trump even questioning cruzs faith, calling him, quote, unstable. Youre willing to lie about anything, and then you hold up a bible . Its no good. Ive never seen anybody that lied as much as ted cruz. And he goes around saying hes a christian. Reporter is senator ted cruz really the dirtiest politician youve ever come across . Well, no, not the dirtiest. Hes the biggest liar. Reporter cruz today says trump is cracking under pressure. Its not a response, simply to start yelling louder and louder, liar, liar, liar, whenever anybody points to the candidates own record. Truth matters. And were not in grade school where you just get to say liar, liar, pants on fire and not respond to the subject. And tom llamas with us live from charleston, South Carolina, tonight. Tom, trump threatening to sue ted cruz himself, saying hes hired a lawyer tonight, but also, taking aim at the rnc, trump bringing up the notion of running as an independent again . Reporter thats right, david. This goes back to this weekend, when trump was getting booed at that debate. He claims the rnc is stacking the deck against him, putting people in the audience who are against his campaign. Tonight, the rnc saying every candidate got an equal number of tickets, and there were only ten donors in the audience. And david, just behind me, president george w.

Hillary clinton was supposed to be here in florida today. Instead, she stayed in nevada. This is who showed up in her place. We keep rewarding people who tell us things they know they cant do, because it pushes our hot buttons. We cant go forward together. Reporter bill clinton going after Bernie Sanders and coming under fire himself from this trump supporter. You liked his money. You took his money. I certainly did. Reporter the former president , firing right back. I took his money for my foundation, where i used it to better than hes using it now, i guarantee you. Reporter later, i asked clinton about nevada. You seem like you are nervous in nevada right now. Should you be . Its a caucus. Any time you got to caucus, its more unpredictable, so, its better for her to stay there. Reporter sanders feeling so confident, hes leapfrogged ahead to michigan, where he was met with huge lines and nearly 10,000 supporters, all feeling the bern. And cecilia vega with us live tonight. Cecilia, you were telling us the Clinton Campaign signaling its closer than theyd like in nevada. What are they seeing in South Carolina . Reporter well, they see a much more positive outlook there, david, and they are banking on support from africanamerican voters. And Hillary Clinton seems to be starting that push early, tomorrow, meeting with community leaders, including al sharpton, in new york city. David . Cecilia vega from florida tonight. Cecilia, thank you. Now, to the other battle brewing tonight, over the Supreme Court, after the sudden death of justice scalia. The haers car the hearse carrying his casket arriving in virginia, amid a fierce debate over who will replace him, and who will choose his replacement. Republicans vowing to block anyone president obama nominates. Abcs chief White House CorrespondentJonathan Karl tonight, with who the president might nominate, and if they have any chance of getting confirmed. Reporter the flag is at half staff today at a snowy and peaceful Supreme Court, but the epic political battle is just beginning. The 79yearold scalia had been on a weekend quailhunting trip at this ranch in texas, when he was discovered in his bed. He was totally peaceful. Hes a man who went to sleep and just didnt wake up. Reporter even before scalias family and Court Announced his death, senator ted cruz fired off this tweet. Justice scalia was an american hero, cruz wrote. We owe it to him and the nation for the senate to ensure that the next president names his replacement. Within an hour, Senate Majority leader Mitch Mcconnell drew the battle lines, declaring, this vacancy should not be filled until we have a new president. Then, president obama weighed in, paying tribute to scalia, but making it clear, hes ready to fight to replace him. I plan to fulfill my Constitutional Responsibilities to nominate a successor, in due time. Reporter the drama jolted the campaign. The republican candidates taking the debate stage just minutes after the president spoke. I do not believe the president should appoint someone. Its called delay, delay, delay. Reporter now, republicans suggest they may not even hold a hearing on president obamas nominee, no matter who it is. And today, Hillary Clinton signaled shes ready to make that a campaign issue. Im hoping that well get somebody nominated that everybody will say, hey, the only reason to block this is pure partisanship. And so, do your duty. Reporter the list of possible nominees includes merrick garland, chief judge of the d. C. Circuit court of appeals. A moderate who had won praise from republicans. Circuit court judge jane kelly, wellliked by fellow iowan chuck grassley, the republican chair of the Senate Judiciary committee. And sri srinivasan, confirmed by the senate as a Circuit Court judge 970, just three years ago. And jon karl with us live tonight from the white house. Jon, is there precedent here . When was the last time the president nominated a Supreme Court candidate in the last year of his term and then got that nominee approved . Reporter well, Election YearSupreme Court vacancies are extremely rare. The last president to nominate and confirm a justice was fdr, back in 1940. And there was a big difference, david. Back then, the democrats, fdrs party, controlled the senate. All right, jon karl with us tonight. Jon, thank you. And as jon pointed out there, with Justice Scalias absence, just eight justices remain. And take a look at the makeup of the court with scalia. Five conservative justices, four liberal justices. In some major cases, the court splitting 54. But with the death of justice scalia, an evenly split court now. And so, abcs terry moran tonight, who has covered the Supreme Court for years, on scalias legacy, in life and in law, and his unlikely friendship with one of the most liberal justices on the court, ruth bader ginsburg, and her words tonight. Reporter to friends, Justice Antonin Scalia was first a family man, a happy family man, as he noted when he was sworn in back in 1986. Maureen, who is an extraordinary woman and without whom i wouldnt be here, or, if i were here, it wouldnt have been as much fun along the way. Reporter they raised nine children together, five boys, four girls, and dozens of grandkids call along. On the court, scalias loss is incalculable. In some of the biggest cases on the docket, the justices are now likely deadlocked, 44, and that means no ruling. So, Lower Court Decisions remain standing, likely handing huge victories to public unions, representing teachers and other government workers. They now will likely get to keep millions of dollars in mandatory fees from workers that were being challenged. And on voting rights, a republican effort to change how electoral districts are drawn, now expected to fail without scalia. Beyond the cases, there is the personal loss for justices. Especially ruth bader ginsburg, their friendship so evident whenever they were together. We do also have a different style. Id say, people might regard my opinions at rather dull, boring. Yours are really jazzy sometimes. Jazzy. Reporter in a heartfelt statement, Justice Ginsberg saying, he was a jurist of captivating brilliance and wit, with a rare talent to make even the most sober judge laugh. And terry moran with us live tonight, and terry, if we dont have a new justice until the next president takes office, that would obviously be about a year or more, has this happened before . And what does the court do in the meantime . Reporter you know, it has happened, david. Back in the 1950s, Justice Jackson died at the beginning of the term, and the court basically kept on with its work as best it could. They do have the option of what you might call a doover. They can rehear a case, but basically, the bottom line here is, its not a great situation, but the court, on most cases, doesnt need to decide the issue tomorrow. David . Terry moran with us tonight from the court. Terry, thank you. Overseas tonight, and to syria, and just days after the u. S. And russia announced a deal that would pause fighting there, tonight, a search for survivors after deadly air strikes. Hospitals and a school reduced to rubble.
