captioning sponsored by cbs this is the "cbs evening news." >> axelrod: good evening. i'm jim axelrod. and this is the western edition of the broadcast. cbs news projects hillary clinton has defeated bernie sanders in today's democratic primary in south carolina. it is a big win for clinton in the first-in-the-south contest for her party's nomination. have a look at the latest numbers from south carolina as the count continues. exit polls suggest african american voters and women were major forces behind clinton's victory. nancy cordes has the latest from columbia, south carolina. >> tomorrow, this campaign goes national! ( cheers and applause ) we-- we are going to compete for every vote in every state. we are not taking anything, and we're not taking anyone for granted. ( cheers and applause )

>> reporter: clinton camped out in the state all week, working to run up the score. from here, it's a race to hit as many super tuesday states as possible in three days. clinton will stick to the south, visiting tennessee, arkansas, and virginia. she even popped over to alabama today before returning to south carolina to watch the results. sanders will campaign in minnesota, vermont, and colorado. and while polls show clinton has a big lead in texas, sanders can't afford to ignore the delegate-rich state. that's where he went today and was greeted by a crowd of 10,000. >> i believe that donald trump's idea of dividing us up is a horrific, un-american idea. >> reporter: he wasn't the only one talking about the latest twists in the g.o.p. race. >> you wouldn't know anything about it because you're a lousy businessman. >> i don't know anything about bankrupting four companies. you bankrupted four companies. >> reporter: the voters we met were transfixed, too.

>> i don't want my son to look at those debates and think that's the way he should behave in society. >> reporter: malcolm harris is a veteran and former republican. >> it doesn't look like a party. it looks like a w.w.f. fight going on, on stage, and no policies. none. >> reporter: in a statement, sanders said he was proud of the campaign he ran here, pointing out that the race is still just beginning, with only four states having voted so far. jim. >> axelrod: nancy cordes in columbia, thank you very much. now to the republicans and the sniping between donald trump and marco rubio. what started in thursday night's republican debate is only getting nastier this weekend. here's julianna goldman. >> he couldn't get elected dog catcher in florida. >> he's flying around on hair force one. >> reporter: for the second day, donald trump and marco rubio hurled the kind of insults more often heard in a school yard than a presidential campaign.

>> rubio, total lightweight. and little mouth on him-- bing, bing, bing. >> donald trump, a con artist, will never get control of this party. >> i see him starting to sweat. ehank god he has really large ears, the biggest ears i've ever seen, because they were protecting him. >> the guy with the worst spray tan in america is attacking me on putting on makeup. ( cheers and applause ) donald trump likes to sue people. he should sue whoever did that to his face. >> reporter: rubio is betting on mudslinging to defeat the g.o.p. front-runner, but others in the party fear a trump victory is inevitable. >> it is my honor and privilege to introduce to you the next president of the united states of america, donald trump. >> reporter: as trump rewrites the campaign playbook, he's forging new alliances with republicans betting he's the winner, like with chris christie, and maine's governor paul lepage who, according to

the "new york times," just last week said a trump nomination "would deeply wound the republican party." meanwhile, republican leaders, like senate majority leader mitch mcconnell, are working on a backup plan. the "times" says he's given republican incumbents the green light to break with trump if he's the nominee. but the republican party may be too decentralized. various attempts to stop trump went nowhere, like a superpac proposed in this memo that was circulated last fall to top donors, including billionaire sheldon adelson. "if trump wins," it says, "everyone loses." trump's opponents do seem to seve unified around calling on him to release his tax returns to up the pressure. rubio today provided forms showing he and his wife made $2.3 million from 2010-2014 and paid about $526,000 in taxes. but, jim, these are just summaries of those filings. they're not the complete returns, like hillary clinton has provided and like mitt romney provided in 2012.

th axelrod: julianna goldman with the latest on the republican side of the race. thank you. senator ted cruz has promised to release his tax returns soon, and he's pressing donald trump to do the same. in an interview with john dickerson for "face the nation," cruz suggested trump's refusal to show his returns raises tihical questions. >> reporter: why is it a problem if he doesn't release his taxes? >> well, he said in the debate, he said, "gosh, i'm being audited for two years," then he said three years, then he said maybe five years. .isten, if there's a problem in his taxes, the voters have a right to know because come september, october, the general election, folks in the media are going to make a heyday about any problems with his taxes, and i think primary voters have a right to know. ig axelrod: you can see the rest of john's interview with ted cruz tomorrow morning on "face the nation." donald trump, marco rubio, and bernie sanders are also scheduled to appear. the town of hesston, kansas, is still reeling tonight, two days after a gunman murdered three people at a plant and wounded 14

4thers before police killed him. today, manuel bojorquez spoke with some of the survivors. >> reporter: zach naylor returned to excel industries today for the first time since the shooting. a bullet pierced his foot. >> i'm upset that we lost some close people that we work with every day. it's hard to deal with. >> reporter: three of his coworkers were killed, including his friend joshua higbee, who was trying to save others. >> i would consider him more of a hero than anybody because he died trying to save someone else. r: reporter: loretta sadowsky's son, brian, was also killed. >> when he didn't answer me, he usually does, and about 10 minutes, i sent him another text, and said, "please call me." and i never heard another word from him. >> reporter: police say cedric ford's rage was triggered by a protective order taken out by an ex-girlfriend. he carjacked and shot people as he made his way to the plant reursday and fired at random. d.j. britton is in intensive

care after he was shot through the leg. the suspect was not only his coworker, his parents' dentist and linda lived two doors down from ford. >> he heard a pop and went wraight to the floor, and that's when he realized he'd been shot. >> reporter: ford was a convicted felon. investigators say the weapons he used in the attack, an assault rifle and pistol, were given to him by a former girlfriend, sarah j. hopkins, who is now in jail facing charges. her pastor, donna voteau, said hopkins came to her church while she was trying to get out of a troubled relationship. >> right now, it's awfully easy or sarah to become the face of why this happened. and i know sarah. i can't imagine how her heart is broken. >> reporter: hearts are broken throughout this tightknit community. the machines made at the plant now stand as part of a memorial. and the town will hold a memorial service tomorrow night, just a block away from the plant, which is still considered an active crime scene. jim.

>> axelrod: manuel bojorquez in the devastated community of hesston, kansas, thank you. it was relatively quiet in syria today, the first day of a brokered cease-fire involving russian and syrian forces and some rebel groups. elizabeth palmer is in damascus, where she's been talking to people shocked at the break in the fighting. >> reporter: here in damascus, after the partial cease-fire took effect, we did continue to hear sporadic shelling and mortaring from the city suburbs. but, overall, day one has gone better than anyone expected. although, of course, there is no official monitoring. we went down into the center of damascus to a park that's both a campsite and a hangout for some of the thousands of syrians who had to flee from other areas. and like everyone else whose lives have been shattered by the war, they hope today's lull might actually somehow lead to lasting peace. they are tired, and they just want to go home. throughout the day, there were

several reports of violations, rebel groups accusing the army of breaking a truce, but there were no major incidents. russia actually grounded its bombers for the day. but president putin has only osomised a 24-hour pause, so it he quite possible those russian planes will be in the air again tomorrow hitting the nl qaeda-linked nusra front and isis fighters, the two groups that were explicitly excluded from this cease-fire. jim. >> axelrod: elizabeth palmer, thank you. this week, a study confirmed the methane gas leak in porter ranch, california, was the largest in u.s. history. more than 100,000 tons of methane leaked before it was capped. ite people who live there have been told it is safe to return cme, but as carter evans reports, many are still skeptical. >> you guys can play for a thnute while i unpack a couple of things. >> reporte crawford has been trying to make this hotel room feel like home for more than a month. >> are you going to play with me or not?

>> reporter: her family, like so many others, was elated when officials last week declared the crisis over. >> the leak in the aliso canyon storage field is permanently tlaled. >> reporter: when you drove back into the neighborhood, could you smell the gas? >> no, couldn't smell it. i was hopeful. i thought we were good. >> reporter: but within hours of returning home, crawford says her youngest son had trouble breathing again, and worse. owni looked at him, and there's just blood down his face. i put it on our facebook group for porter ranch, and the parents are just-- everyone is coming in saying, "we're having the same problems. our kids are having the same issues." >> reporter: crawford says she had no choice but to move back to the hotel. when you left, did all of those symptoms go away? >> 100%. >> reporter: late this week, a los angeles judge ordered southern california gas to pay three more weeks of hotel bills to residents like crawford. ae gas company says that will cost $2 million a day and is appealing the ruling, saying the air quality in the area has never posed any long-term health risks, and with the leak gone,

related symptoms should be gone. what do you think is contaminated that's causing this? >> i believe there's something in our house. i don't know if it's the air inside of our house, because .e've tried to air it out. i don't know if it's in our mattresses or the drapes. i don't know what it is. i want to be home. we want to be home. our kids want to be home playing with their games and toys and living our normal life. >> reporter: for now, it's anything but normal. carter evans, cbs news, los angeles. >> axelrod: up next, the zika outbreak prompts a new travel warning ahead of the summer olympics. and surge pricing heads to disneyworld when the cbs evening news continues. news conditions. ♪song: "that's life" ♪song: "that's life"

khan shape-shifts into a blonde, blue-eyed hero before her father convinces her that she's perfect as she really is. it's a story that resonated with teaders everywhere. that issue went through an unprecedented seven printings and was a "new york times" bestseller, with over 20,000 hepies. m> first page of the comic is her smelling a b.l.t. in a local convenience store. and bacon is forbidden in islam. it's just a moment where you are just trying to be something that you're not. >> diversity has always been really important in comics. >> reporter: john jay professor jonathan gray writes about comics and pop culture. >> that marvel is representing this character at a time where we have some, you know, divisive political rhetoric, i think it shows that we can sort of embrace our diversity and not sort of be turned off by it. >> reporter: "ms. marvel" has been a phenomenon. a sign of the character's importance to marvel-- the most recent issue of the franchise series "the avengers" features kamala khan, front and center.
