Reporter by order of the governor, flags in arizona flew at halfstaff today in memory of petty officer firstclass Charles Keating iv. His teammates in the navy seals where his brother also serves called him c4. Since he was the fourth to bear what in arizona is a household name. His grandfather, Charles Keating jr. , a champion swimmer during his College Years was the financier sent to prison in a bank scandal that implicated several u. S. Senators. His father, Charles Keating iii, was a threetime allam can swimmer at indiana university. C4 was a star distance runner in high school. Where track coach rob renwicki remembers him as the the kid with the Million Dollar smile. A big heart. Big smile. Happygolucky kid. He was the kind of kid that walked into a room and, the room lit up. Reporter after high school he ran for indiana, but left college to join the seals. Beginning with the notoriously tough basic training, and going on to serve two combat tours in iraq and one in afghanistan. Ribbons on his chest include a bronze star with valor. He quietly married before he left on what turned out to be his final mission. Back to iraq, this time to fight isis. His commander said he fittingly went down swinging alongside his brothers in a withering fire fight right where he wanted to be. His death got a lot of attention because of his name. But when you find out who c4 was and how he lived his 31 years, you owe him not just attention but as the the governor of arizona said, our thoughts, prayers and eternal gratitude. David martin, cbs news, the pentagon. And thats the overnight news for this thursday morning. For some of you the news continues. For others check back with us a little bit later for the morning news and cbs this morning. From the Broadcast Center in new york city, im scott pelley. Hi, welcome to the cbs overnight news. Im demarco morgan. Last man standing in Donald Trumps path to the republican nomination stepped aside. John kasich dropped out of the race late yesterday, cementing trumps status as presumptive gop nominee. Kasichs decision after ted cruz suspended his campaign tuesday night following trumps victory in the indiana primary. Here is major garrett. Donald trump trounced ted cruz in a race where cruz had the oneonone shot he longed for and backing of antitrump super pacs running ads. Across indiana. In victory, trump asked hostile republicans to accept reality and unite behind his cause. For some republicans reality is a cause for concern. Tonight, im sorry to say, it appears that path has been foreclosed. Reporter after a brutal defeat all that was left for ted cruz was the ugly truth. We are suspending our campaign. Reporter cruz spoke passionately of enduring conservative principles never mentioned trump brooding over antiestablishment voters he failed to win over. Together we left it all on the field in indiana. We gave it everything we have got. But the voters chose another path. Ted cruz, i dont know if he likes me or if he doesnt like me. But he is one hell of a competitor. He is a tough, smart, guy. Magnanimous, subdued, donald trump began to confront reality. Becoming the likely nominee of a party still deeply divided. I didnt expect this. I didnt expect it. We want to bring unity to the republican party. We have to bring unity. Reporter more than half of Indiana Republican voters said the nomination battle divided the party according to cbs news exit polls. A quarter said they would not vote for trump in a general this country which is very divided in so many different ways is going to become one beautiful, loving country. The democratic side, Bernie Sanders defeated Hillary Clinton indiana. Clinton is on track to face trump in the general election. Here is nancy cordes. That sanders win in indiana got overshadowed by the big news about trump. Democrats know certainly who their republican opponent will be. They made it very clear how they feel about that. I feel good. I just feel generally good. Reporter for weeks clinton has been hedging her bets when it comes to her likely opponent. Both trump and cruz. Trdonald trump and ted cruz. When i hear donald trump say what he says or ted cruz say what he says. Reporter last night, 43 minutes after cruz dropped out. She tweeted. Donald trump is the presumptive gop nominee. Chip in now if you agree we cant allow him to become president. Trump spread hate. And we will defeat him in november. Congressional democrats began offering free stickers. Bearing trumps likeness with the slogan, stop bigotry. Im very excited about this. Clinton are gaud sargued she is uniquely qualified. People ask me all the time, how are you going to respond to all of these attacks . Its not like i havent been dealing with that for 25 years. Really . Unlike trump, clinton must still devote time and money to fending off a well funded primary opponent who has significant support. His surprise win in indiana left sanders more determined to see the race through to the end. Secretary clinton thinks this campaign is over. I have got some bad news for her. Good news for clinton is she and sanders have very similar views on trump. This is a man who does not have the demeanor, does not have the policy background, or the ideas to become president of the united states. Reporter trump unifies the democratics like almost no one else. In fact, senator elizabeth warren, who has largely sat out the primary election sent out a blistering series of tweets last night saying she will do everything she can to fight trump. In one she said, norah, there is more enthusiasm for donald trump among leaders of the kkk than leaders of the Political Party he now controls.

Keating group in arizona where he was a star athlete on his High School Track team before becoming a navy seal. He was a tremendous athlete. Tremendous person. Joyful kid. Reporter the death of keating two miles from the front line in the war against isis shows just how close americans are to the fight. And it calls into question the obama administrations claim that the troops are not serving in a combat role. Men and women on the ground in iraq. Do not have a combat mission. But they do have a dangerous mission. Defense secretary ash carter explained their role to charlie rose. We have boots on the ground in iraq. What are they doing . Theyre training iraqi forces. They are assisting iraqi forces. Engaged in search and destroy. To go out and seek out isil. They are, they are. Absolutely are. Reporter keating the third u. S. Service member to die in the country in the fight against isis. Joshua wheeler was killed in a raid in an isis run prison in october. And louis cardin died in march when isis fired rockets into a u. S. Base outside mosul. Americas role is expanding. Last month, 250 troops deployed to syria, another 200 to iraq. Some even fire artillery alongside fighters. Jim jeffrey, president obamas former ambassador to iraq said denying u. S. Forces are actually fighting is just political spin on a failed strategy. This is a misleading, dishonest portrayal of what we are actually doing. It doesnt show the american people, how deeply involved we are as we should be in the fight against isis. Well be right back.

Now a major american manufacturer is accused of knowingly providing defective gear to Health Care Workers in the u. S. And abroad. Andersen cooper takes a closer look in a story for 60 minutes. Reporter if there is one thing that became evident during the Ebola Outbreak of 2014 it is that personal protective equipment properly used could mean the difference between life and death. You probably remember the tragic images from west africa and the workers in biohazard suits trying to help without getting infected themselves. Certain types of gowns were also used during the outbreak. Nurses at this hospital in liberia used gowns and full body suits to protect themselves after two of their top doctors died of the disease. Every day in the u. S. , doctors and nurses rely on some of the same gowns the centers for Disease Control recommended for ebola. One is microcool surgical gown made by halliard health which sells 13 million gowns a year worldwide including a quarter of the u. S. Market. The microcool gown is supposed to provide the highest level of protection available against blood borne bacteria and viruses. Its label says it meets a rigorous Industry Standard known as amy level four. Which means it is impermable so that blood containing viruses like hepatitis and hiv wont get on surgeons skin during an operation. There its just one problem. What was wrong with the level four gowns . They would like. We pressure tested them especially in the seams. Reporter bernard vizzo was global Strategic Marketing manager for microcool from 2012 to 2015 and work ford halyard health, part of Kimberly Clark.

We put a full court press to drive microcool sales. We told hospitals to stock up or microcool product. Told hthem to have eight to 12 weeks of product on hand. Things became gidifficult. Difficult, he knew the gowns were not consistently meeting Industry Standards. Reporter there is a test for this . A test. Reporter did your gowns consistently pass this test . No, they did not. Reporter was the fda aware . No. Reporter were customers warned . No, not either. Reporter why not. Kimberly clark knew if they told customers it would cost us a lot of business. They didnt tell the public. They didnt tell the fda. They didnt tell physicians. They told no one. They kept selling the gun to the tune of millions of dollars every month. Reporter michael
