it's a simple thing to do to mitigate your risk. not asking people to turn their lives upside down. it simply comes down to try to decrease your risk and waiting for more of these studies to come out. that does it for this edition of "sgmd." thanks for watching. you can set your dvr for 7:30 eastern to get our show every week. more news on cnn starts right now. -- captions by vitac -- www.vitac.com you're in the cnn newsroom live this saturday, may 21st. i'm fredicricka whitfield. we begin with the growing list of republican hopefuls. herman cain announced his candidacy at a rally in atlanta. he is the fourth republican now to toss his hat into the ring. >> this day

this hour, this moment i came to declare my candidacy for president of the united states of america. >> her main cain there. mitt romney meantime is in south carolina focusing on jobs and the economy, also a hopeful for the presidency. it's his first visit to the state since gearing up his political machine for possible presidential run in 2012. so far the former massachusetts governor's candidacy is undeclared. peter hand by is at the event and joins us on the phone from suburban columbia. it's presumed he's throwing his hat into the ring. otherwise, why would he put so much mileage to get his message across. >> it's a game we play. mitt romney is not officially a candidate. he came to south carolina obviously because this state is one of the first four states along with iowa, new hampshire and nevada that kicks off the

presidental nominating process. it's a state he lost badly in 2008 when he last ran for president. he came down here today with the simple message about jobs and the economy. he was meeting with small business owners. one interesting thing i did notice today, he talked a lot about states rights and how he believes in the constitution and how he doesn't believe president obama respects state as much as he does. why is that interesting? the tea party that are currently fueling the party, that's language from sarah palin, rick perry and newt gingrich, not necessarily from the mitt romney wing of the party. interesting to see him test drive that message down in south carolina today. >> meantime, something he was encouraging people to talk about would be health care. he's gotten a little flack over being a bit of a hypocrite as it pertains to health care in massachusetts, universal health care that he encouraged.

then when it comes to national health care reform, he has been on record as saying he sees that as very different and he doesn't like it. how did he explain himself today? >> exactly. that dovetails with the states' rights message. romney's explanation is implemented a plan similar to what's called obama care in massachusetts. he said he did it in a state level, different than mandating the entire country buy into obama care. he knows this is an achilles heel for him. he brought up the question before any voter could. he took about four or five questions from a crowd of small business owners and says i know somebody here wants to address health care. he's getting ahead of it because he knows it's something he can't escape. >> almost as if he feels like it's going to haunt him the whole way through, right? >> that's correct. his staff is very aware this could hurt him in the republican primary. that's why you saw him give that huge speech in michigan just a short time ago to try to get

ahead of this problem. >> cnn's political reporter, peter ham by, appreciate that. people along the mississippi delta today still watching the water levels there. now it is pouring in some areas, making an even muddier mess. take a look right there. pretty widespread. the rain comes as the mississippi was cresting in natchez, mississippi, at more than 60 feet. cn thfrnlths's brian cnn's brian todd. >> these floodwaters have not receded. doesn't look like they're about to any time soon. you mentioned the rain we got earlier today. it made things much worse. officials are now saying that doesn't bode well for the next couple days. we're at an off-ramp outside redwood. you can see the road signs over here. all the roads are closed. we had to have a sheriff's escort to get us this far.

our photojournalist is going to pan to the right. we're told we're several miles in from the mississippi river at this point, we were earlier at a levee holding some of this back up north of here from some of the areas over here. millions of square acres are safe for now. but there is a problem with that one particular levee at lake al b march. they have what they call a slide. that is when the sheer weight of the water weakens the underpinnings of a levee. those underpinnings have shifted, slid about five feet from where they should be, and they are frantically now with bulldozers and backhoes and gravel trucks getting in there and trying to fill some of the gaps. if that thing gives way, millions of acres could be flooded, thousands of homes could be flooded. many more people will be displaced. as you can see, a lot of the other places may look a lot like this, fredicka. this is at crest stage near vicksburg, holding at crest

stage right now at natchez. it crested there at just under 62 feet, 14 feet above flood stage. it's still pretty dire proportions right now. >> thanks so much, brian todd in redwood, mississippi. appreciate that. let's check with jacqui injury ras. >> the critical thing in the days and weeks ahead is these levees -- my fik phone is not on? >> i'm hearing you in an indirect way. >> is that better? >> sounds much better. >> sorry. we had a tour group in here earlier. what brian was talking about was the levees holding. that's a big thing in the days and weeks ahead. we talk about crested versus cresting. the best thing i can tell you is all the major gauges along the mississippi river have now crested or are cresting. the only two that are still

cresting is artificial. it's because we've opened the spillways and floodways. we're maintaining this via other measures. there's still a lot of pressure on this big system. in fact, the river is still in flood which means you're above flood stage, all the way up towards cape girardeau, missouri. so this is a long way where we all this water, all this pressure. we've also had record volume of water moving through here. all that causes stress on this main system. certainly we're not out of the woods yet. take a look at vicksburg. we have crested here. but the river remains 13.8 feet above flood stage. 14.8 feet above flood stage at red river landing -- i cannot say that one, can't i -- natchez, 13.7 feet above flood stage. baton rouge cresting at 9.7 above and holding at 17 feet now in new orleans.

hopefully we'll continue to maintain this as we look ahead, fredicka. there is rain in the forecast. some of that could be heavy. specifically talking about the missouri -- middle mississippi as well as the ohio river valleys. we'll talk a little more about that, tell you how much rain we're expecting and what kind of an impact it could have on that river in about half an hour. >> thanks so much, jacqui. other headlines we're following. in oklahoma a manhunt is under way for two men wanted for shooting an off-duty sheriff's deputy. police say the officer was working at a security guard at a restaurant and was walking to a bank when he was shot in the head. the shooting was caught on videotape which may help identify the attackers. the deputy is listed in critical condition. opening statements are set for tuesday in the casey anthony murder trial in florida. the jury was sworn in late yesterday. anthony is charged with killing her 2-year-old daughter caylee back in 2008 and dumping her body in the woods in the orlando area about a quarter of a mile

from her home. anthony has pleaded not guilty. a major drug bust in mexico. this man that you're about to see had a $5 million bounty on his head. how they got him and the punch this delivers to the drug trade next.

police in mexico arrested who they believe to be one of the country's most notorious drug ring leaders.

that's him in the red shirt. barragan balderas was also wanted in the united states with a $5 million reward on his head. i talked to a former dea agent who told me this bust is a big deal. >> this is machblg or. you've got to remember that this gang was responsible for large shipments over a wlong period of time, own ten years coming from mexico to the united states. you're talking about cocaine, marijuana. also, because they were able to free up the borders and get control over the borders, there was methamphetamine and heroin that crossed the border as well. the taliban claims responsibility for a suicide bombing today in afghanistan. at least six people died when explosives detonated at a military hospital in kabul. a taliban spokesman says two of its members carried out the attack. it's election weekend in spain. voters are picking their local

and regional leaders. protesters turned out last night against spain's economic crisis. much quieter today. by law in spain, people are not allowed to gather and demonstrate the day before an election. clear differences remain between president obama and israeli prime minister benjamin netanyahu over israel's borders. the president has called for a middle east peace settlement based on pre 1967 borders. netanyahu rejects that. the disagreement is fueling tension. here is brianna keilar. >> reporter: israeli prime minister netanyahu was about to leave for the u.s. when president obama made an announcement that infuriated him. >> we believe the borders should be based on the 1967 lines with mutually agreed swaps. >> reporter: at the white house saturday, netanyahu panned the proposal. >> these lines are indefensible because they don't take into

account certain changes that have taken place on the ground, demographic changes that have taken place over the last 44 years. >> reporter: after the initial war of words, the white house hoped the meeting would be a time to kiss and make up. >> obviously there are some differences between us in the precise formulations and language, and that's going to happen between friends. >> we have an enduring bond of friendship between our two countries. >> reporter: for all the niceties, netanyahu drew a line in the sand, and not only on a return to pre 1967 borders, he said israel will not negotiate with a palestinian government supported by hamas or house palestinian refugees. >> that's not going to happen. everybody knows that. i think it's time to tell the palestinians forthrightly it's not going to happen. >> reporter: despite tough words, the u.s. and israel will remain allies even past this rough spot.

the tension between the two leaders was palpable. robert deneen is with the council on foreign relations. >> there's not a great deal of mutual affection there. they've met a number of times. nonetheless, they have not succeeded in establishing a close bond, a close working relationship. they have, but there is not a great deal of deep trust it seems. >> reporter: after the president's meeting, white house press secretary jay carney was peppered with questions about the border issue. he said the president made clear the pre 1967 is a starting point, the mutual swaps would be negotiated. what the white house considers a starting point, israel still considers a nonstarter, even after the meeting. brianna keilar, cnn washington. arnold and maria split. why our legal guys say this might not be another messy

celebrity divorce. and more face to face with venus williams. she says she and serena share plenty on and off the court, but some things are simply off limits. >> on the court, like i said, there are limitations, like maybe we can't talk to each other about injuries are happening because, hey, then the other would need to just take advantage. that's just how it happens in sports. you might want to keep your mouth shut on that. >> they're sisters forever, but also competitors forever. that's straight ahead. am. i'm e name your own price division. i find empty hotel rooms and help people save - >> - up to 60% off. i am familiar. your name? > naomi pryce. >> what other "negotiating" skills do you have? > i'm a fifth-degree black belt. >> as am i. > i'm fluent in 37 languages. >> (indistinct clicking) > and i'm a master of disguise >> as am i. > as am i. >> as am i. > as am i. >> well played naomi pryce.

a probe into the evidence against amanda knox was extended for another 40 days saturday. knocks is the american student convicted in the murder of her roommate in italy. the results of new dna tests had been due today. experts say they needed more time to complete their work. one of the big legal stories this week is also filling the gossip pages, talking about the split between arnold schwarzenegger and maria shriver. the announcement came on the revolution that schwarzenegger fathered a child with family housekeeper. that's more than enough to get our legal guys going. >> let's move on to the arnold schwarzenegger maria shriver case. little dribblings come out every day. now we're talking about the case of maria shriver hiring a fairly well known celebrity divorce attorney, avery.

clearly the couple probably had prenup agreements before they got married, but the wealth changed over the years. they've been married for 25 years. isn't california kind of that 50/50 state? after ten years usually the wealth or the assets get split in half. would that apply here even if there were prenups? >> well, ordinarily, the prenup will expire after a certain period of time, 10, 15 years. they've been married 25 years, fredicka. but the fact is that it is -- california is one of ten community property states that's exactly right, look for a quiet discreet resolution. >> how is that possible? >> in fact, i'm remembering, i think it can be done. i'm remembering you did a face to face with one of the children who talked about her struggle. >> with katherine. >> the bottom line is that's the motive to do this discreetly, carefully, thoughtfully and minimize the visibility which of

course is highly visible now. >> interesting, richard. i don't know if there would end up being a bit of a custody battle at least over the two younger kids. i don't even know if that would be an issue that arnold would try to pursue. >> i agree with avery. it's going to be resolved behind doors, but fred, at this point maria shriver has not said she wants a divorce. >> that's right. >> she's got to want it first. >> you can catch our legal guys right here every saturday, noon eastern time. they're always fired up about some case. be sure to tune in tonight for cnn newsroom special, "sex, lies and arrogance" tonight at 10:00 eastern time. building up our wireless network all across america. we're adding new cell sites... increasing network capacity, and investing billions of dollars to improve your wireless network experience. from a single phone call

it's been four months since tennis star venus williams tore three inches of muscle in her abdomen. unable to play in tournaments for now, she's under strict orders from doctors and training. she tells me face to face as a part owner of the miami dolphins, ceo of fashion design and interior design businesses, she's busy. she explains why it's important to be diverse. >> i do a lot of things off the court. i'm in school for interior design. so i've been taking classes. and also, of course, i have an interior design company. >> v star. >> yes, v star interiors.

that keeps me very busy. >> you already have accomplishments under your belt. you designed a television set as well as -- did you also design the dorms for what could have been the new york olympic games had it won the bid? >> yes. had we won the olympic bid, new york 2012, we would have designed the athlete quarters, which would have been something special because now they're -- there's a bed and a table and that's pretty much it. it would have been something special. that was an exciting project to work on. we just got a new project, too, working with howard university, remodeling the gymnasium there. >> that's my alma mater. >> really. >> it's going to look great. working on a new hotel project in miami. so really getting the wheels rolling and doing some great things. >> where did this come from, where you felt it's important to

diversify myself? people think venus williams, monolithic, tennis great. but you felt it was important to demonstrate that there are other interests, other things, other abilities. >> growing up, my parents, they always said you can't just be an athlete. like a lot of other parents, you have to get good grades. we made a joke, we were allergic to bad grades because we knew there would be big trouble. we never brought them home. we were always encouraged to explore ourselves outside of tennis. our parents took us for lessons for music and languages and we were always encouraged to get a higher education and those kind of things. if i say encouraged, it means -- >> you're going to do it. >> you need to do it. i felt like i had a choice, but maybe i didn't. >> you're going to be 31 in

june. >> i'm going to be 31. >> you've got 21 grand slam titles under your belt. do i have that number right? >> i don't know. i don't count them. >> you don't even keep count? >> no. >> it's not that important this. >> i can count them up quickly right now. it's a good sign if you've lost count, but not so important that i need to keep count. i need to add to that count. >> you met up with your sister some eight times in grand slam arenas, is that about right? >> i don't know. >> you don't keep up with that either. >> no. >> so what is that like when you and your sister are opponents versus when you're playing doubles? >> it's completely different. we're on a team in the doubles and playing against each other. for example, i think there was one year, maybe '08, where i was playing -- we had to play each other in the wimbledon final and the semifinal the day before. i sprained my thumb so bad that

i really couldn't hit a back hand. i couldn't tell her that in the doubles because she'd know in the finals. >> you couldn't even share it with her. >> when it's someone other than your sister, is there a lack of eye contact. are you thinking i just want to run them into the ground? what are you thinking about that person on the other side of the net. >> i guess i want her to go down. i don't know. the main thing in singles especially is to be aware of what your opponent is doing, their patterns and weaknesses, but hitting the best shot i can and putting them out of position. >> "face to face" with venus williams. still out on injury. she's not playing in the french open but maybe, she says, wimbledon next month. we've got more "face to face." guess what her favorite past time is when she's not on the court, plus your viewer questions next hour.

it's hard to imagine the kind of grief a family experiences once a member has committed suicide. bottomless grief and forever unanswered questions. i have two family stories and a mother whose heart will never

hear. from cnn's julie peterson, a story of pain and a family's call to take action. >> the north view titans are down a man. in october their teammate, number 13, will troutwein killed himself. he grew up in a tightly-knit family, 15 when he died, the oldest of four kids. he was pd of his class in elementally school, well liked. like his brothers and sisters, a musician, athlete and all-around good kid. >> very nice. >> reporter: dad john played major league baseball for the boston red sox and is a successful businessman. sue is a devoted mother and the family is active in their church. they say they saw no signs of mental illness. sue found her son. he hung himself. >> the family has been embraced by the community and friends. >> these sheets were hung at the

vigil. one day, one day, we'll sit and read them. >> reporter: they are clear about their anguish. >> there are times when i shut my door and i play a video of him knowing it's going to make me cry, knowing it's going to bring me to my knees, but i get to see him. >> we cry a lot. it's not -- >> part of our will time. >> part of our healing and our grieving. >> reporter: john and suzie insist his death must mark a beginning, not just an end. they started will to live, about kidding gets to be there for each other. >> we just know it's more likely that kids will talk to kids first. so we said, you know what? let's promote it. let's really promote it. let's overpromote it. let's talk about loving each other. >> reporter: they've been spreading their conviction to kids and parents while awaiting nonprofit status, raised tens of thousands with a singular

purpose, to get the word out to kids and their families. >> not only do we want you to love each other, we want you to tell each other you love each other, so they do pick up the phone. whatever will was feeling is very common, but he didn't think it was common. suicide and mental health issues and depression, it's a disease, not a crime. >> reporter: many are taking notice. georgia governor nathan diehl met the family. >> the message is spreads about your family and loving each other are some of the most important you'll ever hear. everyone takes that in open heart. everyone misses will. i think that's the best way to remember him, is to just talk about it and be open about it and remember good things. >> reporter: julie peterson, cnn. >> joining me right now is a mother who knows very well what the trout wein family is going

through. her son nathan committed suicide 11 years ago. >> that's right. >> i cannot imagine a mother, a family, can ever really get over that, can ever feel like they've healed after their child commits suicide. >> i think it's something you continue to go through. there is no other side. your normal has changed and you have changed. the dynamics of your family have changed, yes. >> so the troutweins put together this non-profit organization. you heard the father explaining that the idea here is to let children, young people know that they are loved. but sadly, so often that's not at the root of why a child may commit suicide, if they don't feel loved. given what you've been through, what do you say to families, what are the things they need to look for or what alerts them

that something is awry, something has a hold on my child that they just want to -- they've lost the will to live? >> it's really sometimes very difficult to see. in our case nathan was dealing with depression. we knew he was dealing with depression and he went for help. but we had absolutely no idea that suicide was a possibility. not even his therapist knew that. i think the idea of them having children, having teenagers working with other teenagers, i think the way it helps the best is when they are truly taking the mask down and sharing their hurts and their pains so that the other individual feels safe enough to share what they're going through. >> let's talk about some of these peer-to-peer talking points that people can perhaps really identify with. we've built a screen here so

people can see visually the reference as we're talking about it. you know, telling the story, expressing their emotions, telling young people, if you feel like you can't tell your mom or dad or another adult, a family member, a guardian, aunt or uncle, you've got to tell one another what is troubling you. express those emotions, and you say, you know, i guess try to help them explain what the meaning behind the loss or that feeling of loss is all about. >> i think many times they feel very alone in what they're dealing with. and in all honesty, i think it almost starts with with the parents, being able to open up freely with their children when they are going through situations that are fearful and they are scared. i think it almost has to start with the parents. it helps greatly when you have children, when you have teenagers sharing and being able to approach it that way, by

opening up themselves to one another. i think it's the aloneness. he even mentioned it, he thought he was the only one. that's what happens. many times they can start isolating themselves as well. so it's -- those are the visuals. you can see isolation with our son nathan. he slept a lot. he did not like loud sounds. there were a lot of dynamics going on that we did not pick up. but since his death have come to realize there are a lot of dynamics playing out here that we had no idea. because they talk about depression so freely where before it was something you don't talk about, but there are so many young people as there are so many adults that are dealing with depression and feeling isolated and alone. >> that has to help tremendously now that there's acknowledgment

from this day forward that people are not afraid to recognize or not afraid to articulate and say out loud that i'm feeling this. because if there's this on going dialogue, that ultimately is good to help in that kind of communication. thanks so much. it's been a very difficult 11 years with the loss of your son and our hearts go out to you. >> thank you so much. it was really nice to be here. >> thanks so much. we'll be right back right after this.

this week's cnn heroes have spent more than $100,000 on child adoptions. here is a look at how they're helping others to adopt. >> i don't care how you become a mother, it's a miracle. one of them making the other one laugh is just the greatest noise ever. i waited a long time for that kind of noise. jake and brook are both adopted. to adopt our two children it was over $100,000 in after-tax money paid in full, paid up front. adoption in this country can cost between $30,000 and $50,000 depending on the situation. >> there are plenty of loving homes out there. the only obstacle is this cost of adoption. my name is becky fawcett. i started an organization that

helps people complete the cost of their adoptions by awarding financial grants. as a little girl, i dreamed of being a mother. our applicants are hard working, educated americans. >> she's the light of my life. she's everything to me. the expenses were insurmountable and scary. the mother that i received from helpusadopt.org took a lot of weight off my shoulders. we helped to build 43 families since 2007. we're helping people bring their children home. we're helping all types of families. we believe in family, period. we believe in loving a child, period. >> where is brook? >> my journey to adoption is the best thing that ever happened. those speaking adoption, there is a happy moment at the end of your story. it takes us all a long time to get there. but it's worth the wait. >> we always want to hear from

you. tell us about the heroes in your community. send your nominations to cnn.com/heroes. checking our top stories right now. a new name has been added to the list of gop presidential hopefuls. herman cain officially declared his candidacy today. the former ceo of godfather's pizza said he needs to run because the nation is in a crisis, in his words, economically and morally. he's seen as a tea party favorite. dominique strauss-kahn is out of jail, released from rikers island after posting a million dollars cash bail. the former imf chief is confined to a manhattan apartment under the watch of a security guard which he is actually paying for. he faces sex crime charges. a new york hotel employee says strauss-kahn tried to rape her last week. a major drug bust in mexico, not actually drugs but a drug runner.

trying to get their catch before the floodwaters rede stroi them. rob marciano reports from terrebonne bay. >> reporter: greg's family has been farming oysters here for more than 100 years. >> this is basically where the fresh and the saltwater meet. >> reporter: perfect for oysters. but get too much fresh water like during a historic flood and the oysters die. >> being out on the water, there's a lot of unexpecteds. it's very similar to harvesting any crop out in the land or out on the water. >> it's been a lot of back to backs, katrina, gus taf, oil spill, now this stuff. >> ike. you missed that one. >> it's been tough for you guys. >> we just have -- you know what? there's a little bit of pirate in each one of us. i think you figure your way

through it. >> reporter: we tie up to a working boat to check on his crop. >> once everything is on the table, these guys go to town and they start working the oysters. >> they're going to town all right. look at the harvest so far. we're not even mid morning. what kind of take will you have on a day like today? >> we'll probably end up with about 50 sacks which is about 5,000 pounds. >> time to sample the product. >> stick your lips on the meat and slurp and chew all the yummy goodness. what do you think? >> wow. somebody shut the flood gates. save me the oysters. fresh water does not affect the taste which keeps him motivated to get through what will be another tough year. >> you still have that flavor in your mouth of that oyster, and you can taste it. that's what keeps me going in this business, is what we just

did. >> reporter: rob marciano, cnn, terrebonne bay. >> frightening times for so many people along the mississippi. jacqui jeras in the weather center. frightening stuff. impacting commerce on so many different levels beyond other lifestyles and livelihood of people. >> absolutely. you have the fishermen, the farmers, people that ship stuff up and down the mississippi river. lots of different levels we're talking about. the good news is the river for the most part has crested or is cresting. so i think we've seen the peak now or we're in the very tail end of that peak. we need the levees to hold for another couple weeks because so many places are still in flood. one of the other things we're concerned about is the threat for more rain, right? this is something we're going to be watching in the upcoming days. not a lot of heavy stuff today. in the coming days, we'll see this more active weather pattern that's going to bring in showers and thundershowers and some of these individual storms could

bring as much as two inches per hour. we're focusing especially, right up here, talking about the middle mississippi river valley into the ohio river valley. the next five days could see as much as maybe three to six inches of rainfall. that will likely be detrimental. keep in mind, the ohio river goes right into the mississippi, doesn't it? remember the whole thing with the bird's point levee exploding in the cairo area. we'll watch this area. at this time our thinking is it's not going to be enough to make the river go back up, but it could be enough to keep that level higher for a longer period of time. now, something else we have to worry about is that the thunderstorms developing today are likely to be strong, possibly severe. we're watching an area from southern minnesota, stretching all the way down into parts of texas. we have two watches issued here in the last hour you can see one, dry line thunderstorms, possibly supercells possible.
