Steals dozens of weapons. An energy tycoonidize at the wheel one day after his indictment. And the most super of the super tuesday returns. Scottie kelly, back on mother captioning sponsored by cbs this is the cbs evening news with scott pelley. Pelley their taillights are getting smaller as frontrunners donald trump and Hillary Clinton race down an open road toward a nomination in the summer and a faceoffer in the fall. Trump has won 10 states, seven on super tuesday. He now has more than a quarter of the delegates he needs. Today, republican candidate ben carson said he no longer sees a path forward for his campaign. And there is only an Obstacle Course left for ted cruz, marco rubio, and john kasich, a nearly insurmountable course because of the delegate math and the nature of the states remaining. Reporter marco rubio voted early today in florida, state that could be his last stand against donald trump. Its an incredible privilege and honor to be able to vote for myself for president , just a few blocks from where i grew up. Reporter recent polls showed rube no trailing by double digit but he contended trump is in trouble. 65 of the people who voted yesterday across super tuesday does dnot vote for donald trump. Reporter ted cruz won his home state of texas and oklahoma but fell way short of his original goal of a super tuesday southern sweep. Still, cruz urged other republicans to drop out. So long as the field remains divided, Donald Trumps path to the nomination remains more likely. And that booing would be a disaster for republicans. Reporter last night, trump held a president yaldstyle News Conference in his mopulent maralago ball room. I know people will find that a little bit hard to believe, but believe me, i am a unifier. Reporter on cbs news, Lindsey Graham wasnt buying it. I think were about ready to lose to the most dishonest clinton. And how could you do that, nominate somebody who is crazy. I think dishonest beats crazy. Former students say Trump University was a scam. Reporter this antitrump ad is part of an 11th hour, multimilliondollar push from big republican donors to derail trump. The frontrunner did not appear fazed. Theyre going to put 20 or 25 million over the next two weeks from what just came over the wires, and frankly, i think thats fine. As far as im concerned, its fine. Reporter 2012 republican nominee and former Massachusetts Governor mitt romney is expected to be sharply critical of trump in his speech tomorrow. Scottie, the current republican governor of massachusetts, charlie baker, said today if given the opportunity he would not vote for trump in november. Pelley and the turnout on was at an alltime historic high. Major garrett on the campaign for us. Major, thank you. Now, on the democratic side, clinton has won 10 states, including seven on super tuesday, and she now has 44 of the delegates she needs. Heres nancy cordes. Yesterday was one for the history books. Reporter clintons super tuesday wins were supersized. She beat Bernie Sanders by 59 points in alabama, 43 points in georgia, and about 30 points in both virginia and texas. In a memo today, her Campaign Manager noted that clintons delegate lead is now, larger than any lead thensenator obama had at any point in the 2008 primary. Clinton barely mentioned sanders in her victory speech. Instead, she took on trump. And we know weve got work to do, but that work, that work is great. Reporter sanders did win four states by double digits. In the southwest, in oklahoma last night, we won by 10 points. Reporter today, his aides insisted hes still in the hunt and could pick up four more states in the next couple weeks. The clinton team argues, in order to catch up, senator sanders doesnt just have to start winning a few states but he needs to start winning everywhere and by large margins. And that wont be easy because right now, Hillary Clinton is leading in the polls in michigan, ohio, louisiana, and florida, four states that vote this month. Scottie, she is celebrating her big victory here in new york city tonight with a starstudded fundraiser featuring elton john and katie perry. Pelley nancy cordes, to make sense of all of this were going to turn now to john dickerson, our cbs news political director and anchor of face the nation. John, theres a lot of talk trump, but how practical is that . Reporter its a long shot. There is definitely motivation. I asked someone involved with the antitrump effort to rank the republican pan identical a scale of 110, and he said 11. But harnessing that panic requires politicians and Party Regulars to organize themselves quickly and theres no leader of this effort. And it requires them to take a big risk. Normally, they dont like to be on the wrong side of public opinion, and theres no guarantee. Attacks from the establishment could very well make trump stronger. Pelley what is one of the most plausible approaches . Reporter i guess the shortest long shot would be to deny trump the delegates needed for the nomination. By launching a withering set of ads immediately in delegaterich states like ohio and florida, which vote on march 15, the hope would be to tear trump down and give some other candidate a chance to win. Then there would be no clear winner, and the delegates could be persuaded to pick someone other than trump in the possibly pelley and looking quickly at the democrats. Does sanders have a shot against Hillary Clinton at this point . Reporter its a very, very distant shot. Hes winning states, but shes winning more than he is. She has a delegate lead. And unless something changes in the dynamic, shes on her way to the nomination. Pelley john dickerson, well be watching sunday on face the nation. John, thank you. Well, as donald trump was pronouncing himself the winner, Mark Phillips tells us europeans were having trouble pronouncing him at all. Reporter theyre trying to figure out the name. And theyre trying to figure out the man. Donald trump was once seen as a peculiar aberration of american politics, even as vaguely amusing. But nobodys laughing now. Instead, theyre scrambling to learn how to deal with him, taking trump lessons from those well, his behavior was extraordinary, childish. Reporter alex salmond was head of the Scottish Government when trump was promising to build a glittering new golf resort there, a promise he never kept. As soon as you said no to the donald, then things soured very, very quickly. Reporter the European Press has been full of apocalyptic foreboding. Madness screamed the cover of germanys der spiegel. Really . Asked the economist. I think there is the unreckonability of donald trump is really what is spooking people. And that is what hes running on, being changeable and pulling the rug out, and being an event. Reporter but if you want to know what people really think about donald trump, try the bookies, where trumps odds are dramatically improving. Alex donohue sets the odds. The trump has shortened up. Hes now two to one. Reporter two to one, scottie, is a pretty good bet. Hillary clintons odds by the way are even better. And heres the sobering thought in recent elections here and in the u. S. , the bookmakers have been better predictors of the result than the political pollsters. Pelley Mark Phillips reporting tonight from the london newsroom. Mark, thanks. In another important story today, the biggest Abortion Case in a decade was argued before the eight justicessing of the supreme court. This one is a challenge to a texas law that imposes tough standards on Abortion Clinics. Patients. Jan crawford is following this. We support abortion care reporter its the courts first controversial case since the death of justice antonin scalia. Protect life. Reporter but the questions from the justices were no less intense and reflected deep divisions. Liberals appeared united that standards for Abortion Clinics would force many to close, ultimately obstructing a womans right to abortion for no good reason. Justice Ruth Bader Ginsburg the conservatives ask wheres the evidence the law would in fact shut down many clinics . Justice sam alito, as to some of them, theres information that they closed for reasons that had nothing to do with this law. Texas passed the law in 2013 amid National Outcry over a pennsylvania clinic where a doctor was convicted of killing a patient and three infants in botched, lateterm abortion. The law requires clinics to operate more like Surgery Centers and have doctors with admitting privileges at nearby hospitals. Texas representative Jodie Laubenberg sponsored a bill. Texas cares about women. Care. Reporter but amy hagstrom miller, c. E. O. Of the Abortion Clinic challenges the law, said that was a smokescreen. This law is cruel and it is harsh, and it does nothing to advance medical health for women. Reporter now, the key vote here, as in all of these Abortion Cases, is the moderate conservative Justice Anthony kennedy, and today he did not tip his hand. Although, he did ask whether the court should send this case back more evidence. And, scottie, that would delay a decision in this case, until Justice Scalias seat is filled. Pelley today, justice came in two infamous murders near the university of virginia. And kris van cleave is at that courthouse. Reporter a shackled Jesse Matthew left a packed charlottesville, Virginia Court after pleading guilty to the murder and kidnapping of College StudentsMorgan Harrington and hannah graham. We miss her every day. Reporter hannahs father, john. Hannahs enduring gift to us wicked man to be apprehended and convicted. She did change the world, but at a terrible price. Reporter graham was starting her second year at the university of virginia in september of 2014 when she vanished. Her body was found six weeks later. Security camera video showed the last person to see her alive was matthew. D. N. A. Recovered during the graham investigation linked matthew to harringtons murder. The Virginia Tech student disappeared after a cons nert 2009. They say it takes a village to raise a child. I know it takes one to bury a child. Reporter morgans mother, jill, welcomed the plea deal. I would say the primary emotion is relief. This has been finding justice for morgan has been a burden on our family for six and a half years. Reporter in exchange for pleading guilty, matthew is spared the death penalty. Instead, he will serve four life skott, through his attorney, matthew apologized to the family of his victims. Pelley in houst orange the police have released an incredible video today. It shows a team of thieves ransacking a gun store. Manuel bojorquez has this. Reporter the dawn burglary in the southwest houston gun shop was fast and furious. The group of men pulled up to the front of the store with a large pickup truck, smashed the windows, attached a chain to the doors, and pulled them right off their hinges. 10 people then rushed in and ran through the store, smashing a row of glass cases with hammers, grabbing handguns by the sack full. At this angle, we see one man scoop up at least four rifles off the bachrach. An early investigation shows the thieves got away with at least 50 weapons. So far there have been no arrests. Federal Officials Say weapons stolen in this type of burglary will likely end up on the black market and could be used in violent crimes. Reporter manuel, thank you. Killed in a mysterious crash.

He took a tiny company, and with innovations to produce natural gas from shale, he made his Chesapeake Energy second only to exxon in gas production. Well, today, alone behind the wheel, he died in a onecar crash. The timing, suspicious. The circumstances, under investigation. Heres omar villafranca. Reporter it was just after 9 00 this morning when 56yearold Aubrey Mcclendons s. U. V. Crashed into the wall of this Oklahoma City highway overpass and exploded into plaims. Police captain paco balderrama. He pretty much drove straight into the wall. There was plenty of opportunity to the roadway and that didnt occur. Reporter the death of the former c. E. O. Of Chesapeake Energy comes one day after the department of justice charged him with rigging bids on oil leases, a claim he denied. Mcclendon was considered a pioneer in the oil and Natural Gas Drilling business. The boon made Chesapeake Energy billions of dollars. In 2010, he told lesley stahl on 60 minutes that america was sitting on an energy gold mine.

He was forced out as c. E. O. Of chesapeake in 2013. Authorities say mcclendon was going faster than 50 miles an hour and was not wearing a seat belt but do not know if the accident was intentional.

Have pulled out the s. U. V. s black box and, scott, theyre hoping that box will tell them more about the circumstances of the accident. Pelley omar villafranca. Thank you, omar.

Every year, more than 22,000 women in the u. S. Are diagnosed, and because it is often caught too late, more than 14,000 die. Dr. Jon lapook has more on this. Reporter todays report found surprising gaps in what we been ocairn cancer, starting with the basic definition. Even though its called Ovarian Cancer, it can start outside the ovary in the fallopian tubes or the uterus. These are all tumors. Reporter dr. Douglas levine heads the Gynecology Research lab at Memorial Sloan Kettering Cancer Center and was one of the report authors. Different diseases. The subtypes of ocairn vaerns all occur in or around the ovary but they have very different origins. Reporter why is that important . When you start to figure out the origins, it tells you information thats important about treatment, prevention, and mechanisms of developing cancer. Reporter prevention is key because right now there is no effective a of finding Ovarian Cancer early, one reason the disease is so deadly. 34yearold morgan melinkoff, mother of three, got genetic testing last fall and learned she was at increased risk. I was not going to gamble with my life, especially knowing they would not be able to catch Ovarian Cancer in the early stages. Reporter so she opted for preventive surgery. In her case, that meant removing the ovaries, fallopian tubes, and a full hysterectomy. I had to do it. Its very frustratingaise patient. Reporter you can screen for breast cancer. You can screen for colon cancer. The precursor cells turn into cancer, and then spread very quickly. We really have a very limited windo of opportunity to identify the cancer cells. Reporter there are often no symptoms or theyre vague. And heres whats alarming, scott. More than half of women with Ovarian Cancer do not get the recommended standard of care, which includes evaluation and treatment by an Ovarian Cancer specialist. Pelley dr. Jon lapook, thanks, doc.
