Pelley this may go down as the week the party of lincoln devolved into a crippling civil war of its own. There was nothing grand in the old partys debate last night ht name calling, mocking, attempts at humiliation reached lows that many republicans would say are ub beneath the dignity of the office that the candidates are d seeking. Maybe it reflected desperation, as time runs short before next weeks super tuesday, which is week likely the last chance to catch donald trump. Today, the race was jolted by an impeccably timed bombshell when Trumps Campaign was validated by one of the last people you might have expected. Heres major garrett. There is no one who is better er prepared to provide america with the strong leadership that it needs, both at home and around the world, than donald trump. Reporter Chris Christie said donald trump is the best d candidate to take on hillary hi clinton and praised his executive experience. Hell provide strong, de he will do what needs to be done to protect the american people. Reporter but when he was a candidate, christi questioned trumps fitness for the white house. We are not electing an entertainerinchief. Ma showmanship is fun, but its not rs the kind of leadership that will truly change america. Reporter the highprofile endorsement turned attention away from last nights debate when, for the first time, marco rubio, trailing trump in his home state of florida, pummeled the billionaire frontrunner with personal and policy attacks. Heres a guy that inherited 200 million. If he hadnt inherited 200 million, you know where donald trump would be right now . Selling watches in manhattan. You hired some workers from poland. Im the only one on the stage thats hired people. You havent hired anyone. An let me finish the statement nt you havent hired one person. He hired workers from poland fr and he had to pay 1 million in o a judgment. Wrong, totally wrong. Reporter after the debate, s trump told us this about rubio. The guys a choke artist. Ago with Chris Christie. I never saw anything like it. Hi he melted. Reporter trump continued the theme on twitter with this never let them see you sweat depiction of rubio and stage makeup and at his press conference. But i saw him backstage and he was putting it on with a trowel. Reporter on cbs this morning h rubio trotted out his own new attack line. Donald trump is a con artist. A con artist is about to take he over the Republican Party. But not a con artist like donald trump. Reporter at a rally in n dallas, rubio turned up the heat as even more. He mocked trumps tweets by trumps misspelling. Letswyatt chocker marco rubio looks like a little boy on stage, not president ial material. He meant to say lightweight, but he spelled it leigh. T he got that wrong. Reporter he then resorted to toilet humor. Then he asked for a full length mirror. Podium goes up to here. But he wanted a fulllength mirror. Maybe to make sure his pants werent wet. Reporter trump hit back, imitating rubios 2013 state of the Union Response when he interrupted his speech to take a drink of water. Its rubio cheers reporter the attacks have t led many in the republican hm establishment to throw up their hands in dismay, as former candidate Lindsey Graham did last night. My party has gone bat bleep crazy. Reporter maines Governor Paul Lepage endorsed trump, arguing donald trump could be one of americas great president s if he put together a good team. Scott, trump left open putting christi on that team, either as a running mate or a cabinet member. Pelley major garrett, thanks. Hi Bob Schieffer has been watching all of this play out today, and. Hes joining us right now. Bob. C reporter well, scott, i must tell you, i thought things couldnt get lower than theyd already reached in this campaign. I mean, the political discourse, but last night it went even below where i thought it could i mean, no discussion of the issues, but people arguing, o screaming, hollering. It was like kids out behind the barn rather than a political debate. And then, as he always does, donald trump has this tremendous ability to change the subject. He rolls out Chris Christie today and suddenly, that debate sud seems like it was years ago. Were talking about Chris Christie. Pelley after 2012, bob, the Republican Party realized it needed to reach out to a much broader electorate, including hispanics and african americans. What happened to that effort . T well, ill tell you, that is what is bothering a lot of ot traditional republicans. Donald trump gets big applause when he talks about building that wall along the border with mexico, but what some republicans are beginning to wonder is, is he really building a wall around the Republican Party, making it impossible for the party now to reach out and to try to broaden its base. Growing segment of our society, and trump seems to be trying to run them off with all of this s talk. He says that hispanics love him, but the polls dont back this ck up. And i think i think this is the problem that is really bothering republicans now. E ive got to tell you, scott. If they try to run a campaign that appeals only to people who look like me, that is going to be a very tall wall to climb. Pelley Bob Schieffer, on the campaign trail with us for 2016, bob, thanks so much. Thank you, scott. O pelley now to the democrats n on the eve of their South Carolina primary. Heres nancy cordes. Hey, guys reporter the republican r freeforall overshadowed everything the democrats did today, and that was just fine at with them. He in a statement, the Democratic National committee snickered, a superpac supporting clinton overcome by laughter. This was sanders in minnesota. A there are some people out there, people like trump and others, who want to divide us up. They think they can get votes by making bigoted and racist go remarks about latinos, or telling us that were supposed to hate muslims. Up reporter but democrats admit trump would be an unpredictable general election opponent. N new jersey senator cory booker. How do you go up against a nent candidate like trump . U whenever you hit him, he hits back twice as hard. This is going to be a choice for us as american people. Do we want someone who divides ut or someone who unites . H reporter but as a clinton supporter, he knows if she and trump are the nominees it will not be pleasant. C he will go after her constantly, scott, over benghazi and her e mails, another 1,500 pages of her emails are coming out this evening. Of pelley nancy cordes for us tonight. Nance, thank you. In another important story, we mp off the gunman who shot up that factory in kansas where he worked. More than a dozen coworkers were hit and three of them died. Renee benjamin, joshua higbee, and Brian Sadowsky the rampage yesterday began on the road to the factory, and Manuel Bojorquez is in hesston, kansas. My car stopped. He was already out of the car and had this big machine gun. Reporter edna decker was one of 38yearold cedric fords ed first targets. Et what was he like . Angry. Reporter he tried to carjack her, but shot and missed. I could have been his first victim. That died, because it was ed directed right at my head. Ig reporter you ducked just in time. Yeah, i did. Reporter just up the road, ford shot and carjacked another person, then drove that car to t his job, excel industries, in hesston. Inside this building, armed with an Assault Rifle and a pistol, he shot 14 coworkers, killing just 90 minutes before the shooting, ford had been served with a protective order taken out by his former girlfriend who wrote, authorities believe the protective order triggered fords action. Video from his facebook account appears to show him firing a gun. Ford has a criminal record. State and federal investigators are looking into whether he legally obtained the weapons. T. Walton is the Harvey County sheriff. T this man was not going to stop shooting. S the only reason he stopped shooting is because that officer stopped the shooter. Reporter and it wasnt just j an officer. It was the towns police chief, doug schroeder. Kansas governor, sam brownback. Rather than waiting on rn backup, he went right in and did heroic duty and service. Reporter when the police chief stopped the attack, there inside the building behind us here. Scott, late this afternoon, officials said they would charge a kansas woman for giving ford the weapons, knowing he was a convicted felon. Pelley Manuel Bojorquez in kansas tonight. Manuel, thank you. We learned today that the Governors Office in michigan was concerned about the Drinking Water in flint long before the lo lead contamination. Dean reynolds found the proof in the emails. Reporter problems surfaced d soon after the city, under orders from a government appointed emergency manager, switched its water from lake nt huron to the heavily industrial s flint river. It was cheaper that way, but the water was discolored and foul smelling, and people got sick. Jim ananich is a state senator. Time and time again, members of the highest level of the government have clearly been just lying to the citizens of flint and to everyone else. Reporter and now emails from governor rick snyders own was bad early on. In october 2014, a half year into the plan, snyders policy adviser, valerie brader, wrote that elevated chlorine levels could cause longterm damage if d not remedied. Michael gadola, the governors legal assistant, responded, the states Water Quality experts insisted the river water was fine. But independent researchers said re the heavily treated river water was so corrosive, lead from aging pipes was leeching into the water for homes. Today, a contrite snyder held a press conference. There were red flags in this c in the emails if you look at it and beyond emails. We didnt connect all the dots that i wish we would have. Reporter melissa mays was among the first to complain about the water here. When you read the emails today, how did you feel . Furious. I keep telling myself, nothings going to shock you all this time, these people sat in the office going back and forth emailing about this but t nobody stood up and helped us. Ny today authorized a 30 million aid package to help flint s wa getting. Scott, as he put it, people shouldnt have to pay for water they cannot drink. Pelley Dean Reynolds in flint. Dean, thank you.

Its rare for western reporters lmer to get into syria, but our Elizabeth Palmer traveled there today. Reporter the drive in to Sheikh Miskeen is nonstop wreckage, and when you stop, theres silence. Lived here. Now, no one is left. Opposition fighters, a whole te collection of groups working together, were so entrenched here that the syrian army simply couldnt advance into the town. It was a stalemate that lasted a whole year, until they called in un the russian bombers. Wave after wave of air strikes, starting in december, followed by a Syrian Army Ground un offensive, forced the rebels to retreat. Today, there are a few Soldiers Left guarding the ruins as the battle has moved on. The two friends who were killed. Jafar oleyan is an infantry soldier. How fierce was the fighting . I cant even describe it, he says. The rebels had the advantage because they knew the terrain. You must be tired, though . Oh, yes, he says we are so tired. Victory has brought a lull for t regroup, but what if their lull was replaced by a genuine truce . Put your hand up if you think it r has a good chance. If yeah . Yeah, they are ready for this peace. They are reporter ready for the peace. But one soldier adds, if we see isis or alnusra, we will kill them all. Like his country, syria, hoping for peace but braced for a lot more war. Well, its now after midnight here in syria, scott, and so, technically, this partial cease fire is in effect, but its far too early to know where or even if its going to take hold, and, of course, how long it will last.
