hello and welcome to newsroom. on our show, a leading latino lawmakers on capitol hill discusses immigration reform and the importance of the latino vote. also, the latest on apple's inscription standoff with the fbi and other top stories coming out of silicon valley. and how safe is california's drinking water? we'll talk to a reporter about why she tested her own water. first, republican candidates squared off in miami last night for their latest debate. as donald trump continues his strong hold in the race for the white house. trump's controversy remarks have l lead to fissures and prompted

concerned. i'm joined by scott schaffer and by sean walsh, a republican strategist who worked with former california0j÷ governors e schwarzenegger. wyiióáát to you both. sean, your reaction to this morning's announcement from@qñ carson that>he is supporting] endorsing donald trump. this is a man who has.k compar carson to a child !molester, s" he's super low energy, among?ç not9! a pfsurprise.6i just as we sawrf governor chrisi endorse donald y7trump, i think they're seeing thekk writing on going.  on a fairly good politicalvtju)urjz and making themselves relevant for the rest of the political process this year. >> scott, prominent republicans like mitt romney are waging an all out campaign against trump. what role is california playing in that? >> at this point, it's sort of low key. because our primary is not until june. you are seeing for example, the former party chair as the national spokesman for ted cruz. but, you know, just coming back

for a moment to that. ben carson, endorsement today, you noticed how reasonable sounding trump was in the debate last night. and i think we're beginning to see sort of a transformation of the kind of message that trump has had. he's been very outrageous, reality show like during the primaries. but i think as ben carson said when he endorsed him there's another donald trump. i think if he can begin to pivot it's going to allay some of the concerns at least. that you're hearing from silicon valley. >> do you agree that he's pivoting towards a more main stream policy oriented position? >> i think -- i'm not sure he's there pivoting towards a policy position. i think he is reaching out to other people as the field winnows he will want to get their supporters along. i agree it's a little bit of a reality tv type of dynamic in this election cycle. he got a lot of media attention for himself. he is driven -- the campaign has

been driven in a reality tv dynamic. he has to keep that up a little bit to attract certain voters at the same time attract more traditional voters. interesting dynamic he'll have to play. >> you've been involved in republican strategy for a long time. you were a white house press aide during the administrations of presidents reagan and first president bush. how concerned is the california republican party that trump will win the nomination? >> i think you have concerns, california republican party is not monolithic. so you've got a lot of grass root activists. thinking trump can pick up four seats in the house. that's interesting particularly in a state that's so gerrymanders to be honest with you. >> it's not because he think by having trump in the race more voters will show up. >> you will get more voters show ing up. more and more people are actually not identifying as republicans and their falling off.

our voter registration thhas fallen. people are going to the independent camp. at the end of the day you need voters to show up and cast a vote for you. he'll believe you'll get independents. >> wouldn't you say that because the republican party in california has been trying to rebrand itself a little bit, after alienating especially latino voters. if you've got somebody like trump at the top of the ticket it's not going to help the republican party do that, to broaden the tent for republicans in california? >> yeah, i think that's a certain extent true. i think people aregb under think immigration isl5 drivinge latino vote.o recent immigrantsuand immigrants medium jqsized. hanging.qsized. i will tell you something, the immigration issue, people tend to think monolithically in the republican side in california sometimes and at the democratic level that everybody's in, love

with we'll let every undocumented immigrant comeli io the country and we need to have amnesty. that's what drove trumpn" earlyn in the process wasám coming out and being opposed to amnesty. a lot of other republicans were all over the map or couldn't get an answer[down on that. you also have, if you look across the world now, immigration issues all across europe and across the united states that's dividing not just our country but our world. until we get our arms around that, there's passion there. when you have passion people come out and vote. i don't think this is the big winning issue that democrats think it is with some latinos. al i -- >> if you look at the rgpolls, wm are-ññáñ)w-]/z] >> they are because he;rñtéq us inflammatory rhetoric when you talk aboutú rapistac and s$)sr'als -- >> building a ywall. >> building a kúwall, i would t' you if you focus that down,k i think you'll find even> a numbe ofqw latinos who aren't as÷ oppd to ñ$pá element.

came here who waited over a .u$ey did it the5i right way an arel bothered by peopleák who c t2p' $xillegally. mr. ftrump's rhetoric i'm not sure you'll be able toké break enou@% of that in the republica: side and lump it all irtogether >> speaking of immigration, let's talk about thexh 1 b1 vis issue. trump has kind of flip-flopped on that. how are those issues playpath out in silicon valley? how are tech leaders viewing trump? >> you've -- both you guys very good. not in the last debate yesterday although he was moderate and seemed to be pivoting to broaden his reach. in the debate before that he said you know what? i've rethought this hb 1 visa thing. he's reaching out. that's sending a message to -- >> reaching out or flip-flopping? >> the truth of the matter is he's not a career politician. and he doesn't have a history of record on that. he's got an ability most of the other republican candidates don't have. and that ability is to actually

flip-flop, change positions. you know, people say flip-flopping is so bad or so wrong, governor schwarzenegger changed his views and the public accepted that. people are willing to take an outsider who hasn't been involved in the political process and give them the benefit of the doubt. i think he can play that for a long way. >> i think business generally tweeted they like stability. he's waged his campaign so far, it gives pause and perhaps concern to especially the business community, wall street, i mean, he is unpredictable and as rubio says you can think those things and if you're not a candidate you can say those things. if you're president and say things that are riling up the world, whether it's muslims or other companies that could be a problem. >> given the level of volatility and unpredictability how much accuracy is there to reports we're starting to hear about how some california republicans are

so concerned about a trump nomination that they're actually now contacting the democratic party saying we will work with you to help you elect hillary clinton. >> i think there are a lot of concerns particular latly among silicon valley with the trump dynamic. we saw in the last debate and what we saw in the prior debate. that they may pull the trigger. i have three concerns. you may get republicans if he goes on and says i'm a republican for hillary in silicon valley. that's an unhealthy thing for republicans and that will outsize its meaning on the election. number two, big concern is, moderate donors in california were known as the atm of the country. candidates come, the money goes out. atm politics. i'm concerned mr. trump won't be

able to draw from a lot of donors as well as moderate donors across the country. hillary clinton i'm 98.9 certain is going to be the nominee. compete against tnher. >> thank you both for beingua here. politics, i want to stay with uhat a little bit. interviewed co about the latino vote. >> i did. i was curious to see what he had to say. >> let's take a look at thezr interview. congressman thank you. you're not as wellgt-9=]9 in t bay area as you are in los angeles. what should people know you. >> i spent several years in the bay area. went to stanford, undergrad in law school. born and raised in sacramento, california. parents are immigrants from mexico. i'm the first in my family to get a first degree at stanford. my wife i met at stanford. we have three wonderful daughters. >> you're a prominent member of here in california we've got

seven million people eligible to vote who do not register the vast majority are latino. what's up with thc)zx/? >>hc a lot of it is underé óx countries where you were afraid eo go vote. u didn't have ao choice of the vfcandida. a lot of people;9 have never really been incorporated into >> we've got two1g leading republicju running÷ñ for presidgu both cuban american se'ñ rubio. both latino yetmi they seem toãe fighting over who has thef< strongest rwanti-immigrant credent>xs. what do you make of zathat? >> this( is84 america. respect showing that you're latino doesn't mean the only thing you care about. at the same time i think it shows that voters becoming more community. simply because you have a last name that says you're latino doesn't mean you'll gain the vote of the community. >> most people feel in order for

the republican to win the white house they have to get 30% of the latino vote. >> the republican nominee for president, garners 30% of the latino vote this november, hillary clinton is our president. you cannot survive and lose -- by losing 70% of the vote on the fastest growing lect trt. >> that means you'll be in the minority for a while. what can you get done as a minority member of congress? >> i think the conventional wisdom was it would be tough for democrats to win back the house. more likely people say to win back the senate, the five seats we would need. we need 30 seats in the house. i must tell you, the way republicans have sucker punched the middle class, and the way these republican candidates for president have talked about people who work very hard and try to build the country.

there's going to be some heavy wind blowing. and i think if it gets underneath the wings of democrats who are running for office, i believe there's a very good chance that we could see, not just a white house stay in democratic hands but congress also flipping, go back to democratic majority rule. >> i know you thought about running for the u.s. senate this time around. you were offered a post in the obama administration. after he got elected you turned it down. what are your ambition? >> i know that i'm closer to my last days in elected office than i am to my first days. i want to make the most of them. i could have been part of the obama administration. i believe that it was important to try to see if we could get immigration reform, tax reform done. >> you only got one of those done, healthcare. >> immigration reform is happening. it's going to happen. i say it to you. it's as good as done. this is the difficulty, the clock. there are a whole bunch of families that are being

separated. there are republicans and anti-immigrants in this country and some in power who are like the kitten in the poster back in the 1970's who had his claws out on the edge, edge of a ledge. it was looking down. knowing it was at some point going to fall from the ledge. they're going to lose the grip. it's going to happen. it's a matter of when, not if. >> i've never heard somebody say that. >> my dad was born in the u.s. but he is essentially a2cñ immigrant because hek( was rais his parents, myf grandparents manfornia my dad as ax youngwlf would tellyd me the storiesq. e signs outside restaurants that said no dogs or mexicans allowed. a man who couldn't walk into a restaurant got to walk into the president of the united states. >> thank you so much. >> thank you very much. and that was our own senior

politics editor scott schaffer. turning to silicon valley, already this year, many tech companies have been starting to see a slow down. you wouldn't know it from the thousands of tech workers being carried to thee[ peninsula each day. uber is facing challenges(v/om drivers who claim they're employees not contractors. apple's legal fight against the fbi over encryption is heating up. and did you go mnmillen. let's :r' with the apple case, the on going>p battle with the encryption on thepu san bernardino mass shooting. the feds9ñ filed a brief this week, a point by point rebuttal against ap >> they said forget about it. everything that apple is saying

suspect from every fact -- they questioned every fact. they said this is not creating a back door. they repeat that charge. they said that apple is relying on first amendment rights and fifth amendment, that's ridiculous. they just took apart apple's argument. even the little rumor that the feds had asked san bernardino to change the -- back up the phone and change the passcode. they're like that wouldn't make a difference anyway. so basically they dug in and the rhetoric was really strong. >> basically it givers apple flouting the law. >> the law using the -- using this moment for marketing reasons. it was very aggressive. >> yet apple themselves have used every platform to can. we're moving up to day of march 22nd when there will be a hearing about this case. apple is going to get to reply one more time and that's it. >> of course apple has been

making the argument that they can't do this because it's a security issue. and if they build a back door now then hackers could possibly get in as well. is their argument weighing public opinion on this? >> interestingly, it sounds like americans are almost equally divided on this topic. the wall street journal published a poll this week that said 40% of registered american voters worried that the u.s. government won't go far enough to monitor terror suspects. vael siding with the government there. 44% worry that the government would go too far in violating privacy of its citizens which is supporting apple. >> this is interesting to me because this is a court case. one judge that will make the decision. why is this all being played in the so publicly. i think it's because we go to congress, there's bills being discussed. i think feinstein introduced a bill making it illegal to

subvert a legal warrant. i feel like we're moving to a crescendo. what's those people feel really matters. >> yeah. >> the court of public opinion, right. i want to talk also about another court case, this one involving uber. an uber driver in san diego received unemployment benefits after uber kicked him off. tell us about the case. >> this driver essentially was kicked off on the app and filed for unemployment and it may be the first time in california at least that a former uber driver was awarded unemployment, which essentially is like saying he was an employee. at least is entitled to unemployment insurance and an employee would. why was that? this regulator found that he -- uber's ability to fire him, take him off the platform kind of at will was a form of control over

how he did his job. so as -- we talked about before different things that t)át y employee and uhcontractors. one ofat thosepñ is your contro over their ability to doo their job. found that[a uberib exercised that job by firingíj him. it's not cleark whether this is going to set any kind of ]ñ precede precedent. it sounds like@fore uber driverk might be trying to foll [ou'employment. and file for@b >> the other thing that'sz"  is mployment. and file for@b eddp has a share drivers. like 100 questions or!i somethi like that. a questionnaire. soev it seems like theat regula different agencies in sacramento are thinking about this. meanwhile this case is going on where a judge is goingca to"b de the issues. >> doug, you kind of touched on this and michelle maybe you can

so is there or is there not precedent. what impact this might have on the class action suit that's pending regarding uber drivers in california. >> similar to theo w> does it affect thatlh -- it's - theirhs%- dataç' point. laborm commissioners wtimes anus, against us. in sacramento whose job it:ç iso figure out óclassification, conclusion some of t1'áq people are ? employees. >> to the váextent that these court of public &[opinion. there has to be some effect on the future cases and potentially on this really big one that is pending, this class action lawsuit. >> another story that continues to make headlines is yahoo and the ceo gave an interview to charlie rose this week. doug, what did she say?

does she expect to be around next year? >> it's a strange time for her to do big tv interview as you know, yahoo is preparing to auction off its core business potentially. they are, you know, facing a proxy battle in which, you know, star board hedge fund might nominate a whole new board of directors who would end up firing her. yahoo continues -- morale continues to tank and the business continues to have poor performance. why is she going on charlie rose to talk about how great she is doing, the company is doing well. it's a head scratcher. >> do you think she might be trying to convince investors that i still lead the ship have confidence in me. >> yeah, i think she's sending a message to shareholders, give me more time, i need more time for the turn around. >> her brand really pumped the stock up the first two years. do you think it has anymore value that brand?

can she say to shareholders stick with me because i got you this far? >> it's a good question. i think that people in the tech community, a lot of people i talk to, you know, i think that she has lost a lot of credibility out here at least. but when she plays on the big national stage on a charlie rose show maybe she's one of the most successful female executives in tech and business. maybe she still can you know leverage the brand. i think her insistence that her turn around is working and people out here look at the numbers and they look at the momentum there's no loss to yahoo the past few years she a lot a lot of credibility. >> whether sheez right or not, the problem is that the momentum's gone. under her leadership. and life is not fair. and not even to marissa meijer. >> real quickly. what are the lessons learned?

yahoo was a pioneering internet search engine company. >> one lesson is if you're going to take on a turn around, you need to act divisively and need to make big bold bets. one of the main ways she could have done this a little bit differently is by cutting more of the work force sooner that can operate more efficiently. >> thank you both. nearly all the drinkingay@r& water in california meets orox exceedsbá federal and"> state ñy÷z4#rds as acc d discovered contamants still lurk in top water. many÷e communities are being exposed to tcp, a cancer causing chemical that has leeched into ground water. neither the state water board nor the epaq] regulates this chemical.é joining me now, sasha to pock

about this. where doesod it come from and h did it end up in drunking water? >> it was injected in the soil over many decades in farm country in california. places where people were growing crops and wanted to keep worms out of the soil. in places where we've grown crops in california it has leeched down into the ground water. it's been shown to cause;?un%iy in laboratory pxanimals,y@ mult tumors in multiple sites. they extrapolate the!q data fro animals. cause2dne cancer. how concerned should we be?" >> good dnquestion.  25 ye%et onc the prop 65 lis4ña of cancer causin chemicals.

neither the state nor the epa have rules about how much of this stuff should be in our drinking water. the state says it's in the process of finally setting a maximum contammainant level. >> until then your water utility doesn't have to test for this, doesn't have to tell you whether it's in the water and we don't know how big of a problem it is. >> so the water utility doesn't have to talk about it, how did you find out about this? >> you know, i live in the city of fresno. i probably read my water bill more closely than most people. >> the only one who reads the water bill. >> i saw this little tiny foot note at the bottom of my bill, it said 29 wells in fresno have detected it and it's been known to cause cancer in laboratory animals. i brought my fresno water and you can't tell just by looking at the water this chemical is in

there. you can't smell it, it doesn't taste any defifferently. i was worried when i heard that a cancer causing chemical could be in my water. i did get my water tested and we did find there was some tcp present in my drinking water. >> were the lervvelled high enoh for you to be concerned? >> my water came in three times above the public health goal set by the state. folks at the state reassured me that means i have a three in a million chance of getting cancer from drinking the water. i'm more likely to get cancer from breathing smog or second hand smoke. still it's a concern. there are wells in the central valley where the numbers are much, much higher. you know, 100 or 150 times higher than the public health goal. those communities are generally small world communities where farm workers live. they cannot afford to pay water rate increases to clean the stuff up. >> who manufactured this stuff?

are there lawsuits? >> there are in fact. so they've traced it primarily to two companies. dow and shell. both of which manufactured the product for a number of decades starting in the 40s and 50s. and it essentially was a chemical by-product that they ended up using as an ingredient. and some of their own scientists have admitted this was not an effective ingredient when it came to killing nethem. they essentially say they should be the ones to clean it up. it's expensive to put in filtration to clean it up. and small rural communities can't afford it. >> meanwhile,q as that litigatin 6y)áh(ending, when will there b some kind of regulation on jqth? can the public weiól in?aú-by n regulation and starting5ñ in th fall they'll be(] taking public commp6ts. if you're concerned whether this is in your drinking water,

especially if y?cy live in an area that used to be farm country or is farm country. check your consumer confidence report and weigh in with the state resources water board about what you want to do. >> thank you for being vigilant and bridging this to our attention. thank you. thanks. and that does it for us. all of the news coverage please go to our website.
