Now get a 189 per month lease on the 2016 nissan rogue. Good evening. Just when you thought the race for president couldnt get any crazier, we saw escalations on several fronts today. From candidates crying liar, liar, essentially, to new threats of a lawsuit to a war of words between donald trump and the former president george w. Bush, who was out on the stump for his brother jeb tonight. And adding fuel to this inferno there is now an epic political battle looming after the sudden death of a Supreme Court justice, antonin scalia. George w. Bush reporter usually when former president s hit the campaign trail its a reasonably poe heat affair. How are you doing, thanks for your service. Reporter hours before george w. Bush went out to stump for his brother jeb in South Carolina, he got hit by a hurricane known as donald j. Trump. Are you ready . Yeah. The World Trade Center came down during his reign, so he was the top. The World Trade Center came down. Reporter in response, w. Didnt call out trump by name but it was pretty obvious who he was talking about. It is not bluster. It is not theatrics. Real strength, strength of purpose, comes from integrity and character. And in my experience, the strongest person usually isnt the loudest one in the room. Reporter the former president also defended his handling of 9 11, talking about how he reacted when he learned, while reading to a group of schoolkids in florida, that a second plane had hit the towers. My first reaction is i was hot. Were going to deal with these people. My second reaction, when i was staring at this young child, is that my job became crystal clear. And that is to protect her, her community, and her country. I thought it was a little strange that a frontrunning candidate would attack the president of the United States who did keep us safe. While he was building a Reality Tv Show reporter trump is fighting a multifront battle right now, with tminus five days until the South Carolina primary. Ted cruz is desperate. Yeah i think teds a very unstable guy. Reporter aside from slamming the bushes he is also spewing venom at texas senator ted cruz. Single worst liar ive ever seen. The lword is not something you see thrown around much in politics. The fact that donald trump went from and has taken this to a personal level, this is no longer about policy, its about personality. Reporter for good measure, florida senator marco rubio is joining the liar pants on fire choir. Both men accuse cruz of distorting their records. Theres no other word for it but liar. I would note when marco rubio and donald trump scream liar, liar, liar, makes you wonder how they would handle dealing with putin. Cruz trump says hes willing to go past name calling to litigation. Im going to bring a lawsuit because in my opinion, based on what ive learned the past two or three days, he doesnt even have the right to serve as president. Or even run as president. He was born in canada. The World Trade Center came down reporter as you absorb the mayhem in the republican race you probably are worse than jeb bush. Reporter consider that it is now playing out against the backdrop of what promises to be a historic battle set off by the sudden death of Supreme CourtJustice Antonin Scalia over the weekend. I, antonin scalia, do solemnly swear reporter scalia was the longestserving justice on the bench, appointed by Ronald Reagan in 1986. He was a pillar of conservative thought known for his biting dissents and his belief that ruling should be guided by the words of the constitution as it was drafted. Was found dead in his room at this hunting ranch in texas. Reportedly of natural causes. He was 79. Word of his sudden passing hit washington, d. C. Like a thunderbolt. We are one justice away from losing our fundamental rights in this country. Scalias death throws a huge unknown factor into this campaign. It has the potential to scramble the entire race for president. Reporter the constitution says the. Sitting president can nominate the next justice, which is what president obama says he will do. I plan to fulfill my Constitutional Responsibilities to nominate a successor in due reporter but that successor u. S. Senate. Republicans. And in an unprecedented statement just an hour after confirmation of scalias death, the Senate Majority leader Mitch Mcconnell said he would block any obama nominee. The American People should have a voice in the selection of therefore, this vacancy should not be filled until we have a new president. Democratic senator Elizabeth Warren making this counterpoint in a nowviral facebook post. Senator mcconnell is right that the American People should have a voice in the selection of the next Supreme Court justice. In fact, they did. When president obama won the 2012 election by 5 million votes. To have a lame duck president with a party thats the Opposition Party in the senate at the same time as you have this volatile, angry, raucous president ial campaign this confluence of factors has never happened before. Reporter with the makeup of the Supreme Court potentially hanging in the balance, republican president ial candidates are pulling no punches. Senator ted cruz wasting no time releasing a new attack ad just yesterday asking South Carolina voters if they trust donald trump to choose a Supreme Court justice. We cannot trust donald trump with these serious decisions. Debate saturday night in South Carolina, just hours after the news of scalias death broke, a moment of silence quickly gave way to the candidates oneupping one another on who could talk toughest on stymieing the replacement. President should appoint someone. Delay. Were not going to give up the u. S. Supreme court for a generation by allowing barack obama to make one more liberal appointee. Reporter meanwhile the democrats are vowing to put up a fight. Hillary clinton signaling shell make the republican effort to block president obamas nominee a campaign issue. Let me just make one point. Barack obama is president of the United States until january 20th, 2017. Reporter the burning question now, who might president obama nominate . 48yearold srinivasans name is at the top of many short lists. Three years ago his nomination unanimously confirm by the senate. He would be the first Supreme Court justice of south asian descent. 63yearold meric garland is the chief judge of the d. C. Circuit, a widely respected moderate whose name has been floated as a possible nominee before. Patricia millet, also the d. C. Circuit court. The eight remaining Supreme Court justices are scheduled to return from a break next week. They are facing a docket filled with controversial issues including abortion, discrepancy contraception, unions, voting rights, affirmative action. Scalias death means the court no longer has a tiebreaking court. If the eight remaining justices are split on a decision that means the lowercourt ruling will stand. The chief justice could also decide to put some of those cases that would be 44 cases over and have them reargued, presumably after theres a replacement for Justice Scalia in place. Reporter Justice Scalias body was returned to virginia in for now his body remains at this funeral home. No plans announced yet about his ultimate resting place. Meanwhile the fate of his vacant seat still an open and seemingly infinitely contentious question. Next, taylor swift, lady gaga, adele, Kendrick Lamar, highlights from the grammys.

Listen to him tell cnn in 2012 the secret of his marriage of more than 50 years. Maureen made it very clear early on that if we split up, i would get the children. Reporter scalia looked at life with a wry smile and a ready quip. And often his quips had a point. A sharp point. For instance, when the court upheld obamacare for the second his quip with scorn. We really should start calling this law scotuscare, when he wrote in his dissent. When he was asked about the bush versus gore decision that awarded the presidency to george w.
