remember that. arctic express. the bitter blast of sub-freezing cold. bone-chilllling and ngerous. the whiteouts. the accidents. and the new winter storm on the move. 100 million people in the way. and, deadly stunt? the zooming car. then the fiery accident, killing three young women. did a new social media trend, an app that clocks your speed, encourage the young driver to go too fast? good evening. thanks for joining us on this sunday. i'm tom llamas. we begin with the developing news a after t sudden death of supreme court justice antonin scalia. he was a powerful conservative voice, dedicated to defending the constitution against what he saw as the nation's liberal drift.

evenly divided on highly-charged issues. tonight, the battle is set. the future a and direction of this branch of government at stake. we begin with jim avila in el paso, texas, tonight. >> reporter: justice antonin scia died behind the drawn curtains o this room. on this ranch in west texas, scheduled to hunt quail saturday. his body diskofcovered when he skipped breakfast and lunch. the high-e hunting lodge and ranch was host to an exclusive group of mostly texan couples. antonin scalia arrived friday about noon, toured the property,

attended dinner. >> at 9:00 p.m., he said, it's been a long day, had a longg week. i'dd like to be cused. >> reporter: others told investigators they heard the 79-year-old justice he had an illness. the doctor in washington told her hd been ill. the scalia family, his wife, she says objected to an autopsy. and she agreed one was not necessary. >> any signs of foul play could have easily caused, that i asked for an aautopsy. >> reporter: instead, the death certificate will read natural causes, due to his heart

>> thank you. and justice scalia fought hard to defend his positions, but he was able to keep the fight from getting personal. terry moran, closely watching justice scalia in action, and reporting on his legacy. >> reporter: for decades, justice scalia fought to take constititutionalaw back, he says, to its original meaning. >> to impede change, to make it difficult to change. >> reporter: perhaps his great greatest triumph, hisuling on the right to bear arms. it's not the role of this court to pronounce the second amendment gone.

for bush versus gore. we did the right thing. so -- so, there. >> reporter: he was binding, caustic, clclear. he sneered, we should start calling this law scotus care. and he challenged the idea that the court could create a right to gay marriage. >> when did it become uncotitutional to exclude homo sexual couples from marriage? when did it become this? >> reporter: friends with ruth bader ginsberg. >> we agree on a whole lot of stuff. >> reporter: leaving the court shorthanded, and sharply

climate change policies. and tom? >> that leads us to our next story. there's so much at stake, but justice scalia's seat looks to be vacant for a while. president ownbama is vowing to move ahead. here's jonathan karl. >> reporter: the battle lines over jusustice scaa's replacement on the supreme court were drawn in no time. republican presidential candidate ted d cruz tweing this five minutes the supreme court or scalia's family confirmed scalia had died. "justice scalia was an american hero. we owe it to him, and the nation, for the senate to o ensure at the next president names his replacement." less than an hour later, senate majority leader mitch mcconnell declared, "this vacancy should not be filled until we have a new president."

scalia as one of the most consequential thinkers ever to serve on the court, made it clear r he's rea to fight over replacing him. >> i plan to fulfill my constitutional responsibilities to nominate a successor in due time. >> reporter: election year supreme court confirmations are extremely rare. the last president to nominate and confirm a justice in an election year was fdr 76 years ago. but even then, his party corolledhe senate. although scalia became a hero to conservatives and a nemesis to liberals, his own confirmation was entily uncontroversial. he was approved 98-0. even joe biden voted to confirm him. the battle to replace him will play out in congress and on the campaign trail. it's already happening. >> we should not allow a lame duck president to essentially pture the supreme court inhe waning months of his presidency. >> it is outrageous that

the campaign trail have already pledged to block any replacement that president obama nomininates. >> reporter: as for who president obama will nominate, he will likely choose a candidate republicans respect. such as merrick garland, chief judge of the d.c. circuit of court appeals, a moderate who has n praise from republicans. jane kelly, confirmed unanimously by the senate as a circuit court judge in 2013. and finally, sri srinavasan, who was confirmed as a circuit judge 97-0 just three years ago and served in the administration of president george w. bush. he would be the first asian justice. >> jon joins us now from the white house. would it make a difference if president obama would nominate a judge that has already been confirmed?

court nomination is much higher, especially for this one. with the replacemt having the potentl to switch the balance of power to the liberals. >> and dan abrams is here. what happens in a 4-4 tie in a decision? >> there would be a tie. the lower court decision would stand. but it's not precedent. that means the case could end up coming before the supreme court again. >> and if the court was about to hear a case about shutting down abortion clinics, what happens? >> if they were to split, then the lower court opinion would stand. the lower courtrt basically sided

that would mean it could come to the supreme court at a later date. >> dan, thank you. so many people that knew scalia talking about h him tonight. the best way to understand him is to listen to him in his own words. >> a man that has made no enemies is probay not a very good man. >> a conseative maverick, antonin scalia was never one to runway from a fight. bold, brash, poetic in his arguments. >> i love to argue. it may be i am something of a shin-kicker. >> unafraid to speak his mind. >> i'm in the business of enforcing democracy.

debate with each otherer and voted on it. just as they've criticized my opinions and we've remained friends. >> and never losing his step i will certainly retire when i perceive i'm not as good as i used to be. i've lost a step. >> tonight, justice ginsberg saying, he was a jurist of captivating brilliance and wit. with the rare talent to make even the most sober judge laugh. and it's a blow to the conservative movement, the opening topict last night's republican debate in south carolina. after that, the candidates moved on to an all-out brl. cecilia vega with the highlights. >> reporter: in a debate filled with fireworks -- >> i'm sick and tired of him going after my family. my dad is the greatest man alive in my mind. [ applause ]

a reality tv show, my brother was building a security apparatutus to keeus safe. and i'm proud of what he did. [ applause ] >> the worldld trade cter came down during your brother's reign. remember that. >> reporter: there was one moment of agreement. >> i do not believe the prpresident ould appoint someone. >> reporter: the battle to name a new supreme urt justice now playing out smack in the middle of the race for the white house. all six gop candidates on that stage calling for justice scalia's repeplacemento come after president obama leaves office. >> it's called delay, , delay, delay. >> i think that we ought to let the next president of the united states decide who is going to run that supreme court with a votey the people of the united states of america. [ bell ] >> reporter: ted cruz vowing to take the fight to senate floor. >> the senate needs to stand strong and say we're not gonna give up the u.s. supreme court. >> reporter: but that agreement over the supreme court coming to a screeching halt, from a cruz/marco rubio grudge match.

how he knows what i said on univision because he doesn't speak spanish. [ speaking spanish ] >> reporter: to o the wordf the night -- >> when you point to his own record he screreams, "li, liar, liar." >> reporter: hurled at one another no less than 13 times. >> you are the single biggest liar. >> he lied about ben carson in iowa. > that'another lie. >> reporter: and now the focus turns back to the campaign trail. tomorrow is a day of ex-presidents. george w. bush hits the road for his brother for the first time this cycle, and bill clinton is right here. his very f first trito florida so far this race. tom? >> thank you. and we do move on to the arctic chill and looming winter storm. temperatures well below freezing in the northeast.
