suicide bombers, one on a motorcycle, one on foot, targettarget ed cadets in northwestern pakistan. that happening today. the two explosions killed 80 people. the academy is near the border with afghanistan. now, sources say that bin laden's widows, they're not giving up a lot of information. the three women are described as hostile to their american questioners. the interview took place with pakistani intelligence officers in the room. and a source says only the oldest wife spoke. defense secretary robert gates says he is going to pump up security around the navy s.e.a.l. team that took out bin laden. gates says that the s.e.a.l.s are concerned about their safety and the safety of their families because details of the raid have been made public. rain today across the mississippi delta is only adding to the flood misery. the national weather service says the mississippi river is at the highest level ever recorded at natchez and the second highest at vicksburg. the river is expected to rise another six feet over the coming week. well, up river, farmers were just getting their spring crops in the ground when the floods rolled in. this illinois farmer says that the season is over before it even began. >> we had some corn planted that's history, that's under water. it bothers me because it's going to be a tough year. high water may force workers to shut down the waterford 3 nuclear plant in taft, louisiana. now, if the mississippi river reaches 27 feet at taft, flooding would overrun the water intake system that cools the nuclear turbines. it will be close. the crest right now is expected to be just inches shy of 27 feet. we rarely see this in taiwan. amateur video showing a tornado near taipei, the capital, on the northern end of the island. the twister picked up a van and dropped it on a motorcycle. reports say the tornado was 20 stories tall, lasted about two minutes. libyan opposition leaders are due at the white house in just a couple of hours. the delegation does not expect it to meet with president obama but rather the national security adviser. the opposition wants to be recognized as the legitimate government of libya and wants also access to frozen libyan funds. well, the official field for the republican presidential nomination, it doubled today from one to two. two candidates now. texas congressman ron paul formally announced that he is running for the white house in 2012. he follows former white house speaker newt gingrich who jumped in earlier in the week. >> and i am able to announce in this state, a very special state, because there is so high respect for the spirit of liberty here, so i am very, very pleased that i am once again able to say that i am a candidate for the presidency in the republican party primary. here's your chance to talk back on one of the stories that got all of us talking. today's question, are politicians revealing a little too much? tmi, as you like to say, huh, carol? >> yes, way too much tmi. once upon a time when you heard from a member of congress, it was strictly about policy like taxes, foreign affairs or defense spending. are those days gone. dignity seems to be out the window. welcome to the era of tmi. check out this tweet from missouri senator clare mccaskill. i'm tired of looking and feeling fat. maybe talking about it publicly will keep me on track as i try to be more disciplined. off to the gym. it worked for new york senator kristin gillibrand. they took to "vogue" to show off her slimmed-down figure. it's not just a woman thing. male lawmakers also seem obsessed with their political body, so to speak. take aaron shock, proud owner of these six-pack abs on the cover of "men's health." and while we're at it, do we really need to know that barack obama is stinky and snory in the morning or that he hates picking up his dirty socks? it's hard to believe when there was once a time that americans did not know that franklin delano roosevelt was in a wheelchair. we didn't want them to be like real people and certainly not sex symbols. but now it's a topic that carries a lot of political weight and one we can't get enough of because, frankly, they won't let us. so the "talk back question" today, are politicians revealing too much? facebook.com/carolcnn. i'm eager to read your comments later this hour. >> if you have six-pack abs, i think you ought to show them until you lose them. come on! because they disappear. they go away. >> okay. so if you had six-pack abs, suzanne malveaux, would you pose on the cover of "women's health" magazine in a bikini? >> well, no, i would not. those days are over. i wish i could. let's just say that. all right. i'm looking forward to the responses. >> me, too. here's a rundown of some of the stories that we are covering in the next two hours. twin bombings in pakistan are now killed, dozens. the taliban says it's payback for taking out osama bin laden. also, a tennessee man loses everything to flooding, and it's not even the first time. plus, walmart says most of its products are now made in the usa. well, some industry insiders, they're not so sure about that. and finally, don't you hate it it whthis happens? >> meanwhile, other livestock owners -- >> [ bleep ]. >> get it out. >> oh, no. a reporter deals with the not-so-glamorous world of broadcasting. ouch! that looks like that hurt. my cream is what makes stouffer's fettuccini alfredo so delicious. i think you'll find it's the vegetables. deliciously rich. flavorful!

>> well, suzanne, let's remember, these sort of attacks against police recruits and miss recruiting stations were going on long before the american success in killing bin laden. and so this is not really anything new. they've just now taken to using this as the latest excuse to target these innocent recruits who are trying to protect the country of afghanistan and the afghani people. >> do you think that we are going to start to see americans targeted, whether or not it's in pakistan, afghanistan or even potentially on u.s. soil? >> you know what? i agree with what cia director leon panetta said, and that is, look, we ought to expect that. we ought to plan for it. we ought to try and prevent it. but i think you are going to see attempts at retaliation. remember, that was the statement zawahiri issued, al qaeda issued, after bin laden's death is that they would take revenge. and i think we've got to assume they'll be true to their word, if they can, if they can put together the plans and the capability. >> i want to turn the corner here and talk about the safety of the navy s.e.a.l.s that were responsible for killing bin laden. there has been, fran, amazingly what we have seen an active debate that has spilled out into the public about all of the information being released about these. and this is coming from spokespeople from the administration, the white house. there is concern now that this has put them at risk. i want you to take a listen to what secretary gates said. >> frankly, a week ago sunday in the situation room, we all agreed that we would not release any operational details from the effort to take out bin laden. that all fell apart on monday. the next day. >> and fran, you know, the secretary of defense goes on to say, you know, people are worried. the s.e.a.l.s are worried, they're worried for their safety, for their families. when i covered you in the bush administration, you guys ran a pretty tight ship. there was little information coming out of the white house unless you wanted to release it. does this white house, this administration, have a problem on its hands now that it's released this information? >> well, suzanne, while i'd like to take -- i'd like to take credit, as you suggest, for having had it tighter in the prior white house, i will tell you, we were befuddled and frustrated by leaks of classified information. and as you'll recall, president bush was outspoken about it. do i think they've got a problem? absolutely. do i think too much information is out there about the tactical details of the operation? yes. but i think we've got to be careful. this is very difficult for the white house to control. there are now enough people in enough different agencies who have some measure of detail, not all of it, but some. and it's very difficult to get control of it. and we thrive on it. we look for the people willing to talk to us. and it's a real challenge for the white house. i understand secretary gates's concern for the navy s.e.a.l.s. i share that. but some of this, the stealth technology left behind in pakistan, that was out of our control. and the talking about it, all of the concern about it, once we had to leave it behind, i'm sure the administration understood they were going to have to deal with it. >> and fran, the navy s.e.a.l.s, even their families, do you believe that they potentially are in danger? >> look, as long as their identities, their names, are kept secret, there is not a real discernible to me direct threat against those s.e.a.l.s, right? so there's no question that the taliban, al qaeda, are going to look for special forces and try to take revenge. but the particular s.e.a.l.s who are responsible for the operation, the anonymity of those people is their greatest protection. >> and we're just getting information from our pentagon correspondent, barbara starr, u.s. sent this saying that those s.e.a.l.s were wearing those helmets with mounted digital cameras, and officials describe the digital recording as grainy and fast moving, poor lighting. would it be a problem to have that kind of video released, or is it in the best interest of the pentagon, the administration, to simply old n hold on to that? >> they ought to hold on to it, use it for understand the tactics that were used, what was successful, what could be improved on. but under no circumstances should the videotape from the actual raid be revealed because, of course, our enemies could use it to understand the tactics and the methods of our special operators. >> all right. fran townsend, thank you very much. have a great weekend. >> thank you. you, too. more now on the u.s. finally getting a chance to interview three wives of osama bin laden. the women, they were left behind after bin laden was killed in the raid on the compound in pakistan. i want to bring in our nick paton walsh live from islamabad. nick, first of all, an official describing these women as hostile towards the american questioners, these interrogators. what do we know about what came out of the interview and how it was conducted? what have we learned? >> reporter: well, actually, we don't know really anything about what they said. what we do know is that pakistani officials accept these meetings did happen and that the process, they say, were a number of meetings, these separate meetings will be ongoing. u.s. officials giving more details. they're talking about how these interviews were conducted. the three women all interviewed together, and the oldest one of them, a 29-year-old yemeni, speaking on behalf of all three of them through pakistani interlocutors. the spies in the room helping the americans communicate with these women. u.s. officials also present, not exactly ideal interrogation conditions. i'm sure for the americans who would have obviously have liked to have spoken with them separately and tried to work out inconsistencies between their stories, put greater pressure from them. what we know so far, the process is still going on, but they haven't learned anything particularly new. >> so we don't know about any information coming out of the interview, but what makes them hostile? how do we know they were hostile? were they quiet? frowning? cursing? what do we know about that? >> reporter: i think you can imagine, obviously, the atmosphe atmosphere. their husband has been shot dead by u.s. forces. clearly they'll have their own emoti emotions, their own grief, but they were there with pakistani officials, the people keeping them in custody and also perhaps the people who may be in charge of their future. traced back to their homelands and then agents of the government who killed their husband in that particular room. clearly a frosty atmosphere. >> do we expect perhaps they'll get a little bit more information out of them? >> reporter: we are led to understand that it's a process that is ongoing. there should be more meetings. we're not sure what period of time these will be allowed to continue in the future. at one of the worst points imaginable after the bin laden raid and a little light in cooperation might be what helps bring back some sort of future cooperation. >> nick, thank you very much. appreciate your insights. going from made in china to made in the usa. walmart says that it has made the switch. but is it true?

>> reporter: you know what, suzanne? walmart is selling more american-made goods, and it's less about patriotism and more by default because the mix of goods it's selling is changing as americans' buying habits are changing, too. this chart shows just how much stuff walmart sells. it sells a lot of stuff. we all know if you walk through the stores. but the biggest chunk of what they sell are groceries and household goods like detergent, toilet paper and toothpaste. and those products happen to be produced locally. those other items like electronics, toys and clothing, that stuff is produced overseas. and it looks like shoppers are buying less of those items and focusing more on necessities. it really is by default that walmart is selling more american-made goods. suzanne? >> alison, tell us what this means for folks buying at walmart. they count on low prices. does this mean that you're going to see higher prices now? >> reporter: it doesn't necessarily mean that. those low prices will probably stick around because the reality is walmart still depends on those overseas products. so the china factor will still be in the mix. just because those products are much cheaper. and pricing for walmart, it's really a major focus because their typical consumer is low income, so they want to keep those prices down. and they've had a rough couple years with sales. as far as sales go. so that's why walmart has even been cutting prices even more. so no worries. those china products will still be on the shelves at walmart, suzanne. >> all right. thank you, alison. have a great weekend. >> reporter: okay. you, too. every day in vietnam, an estimated 23,000 children are living and working on the streets. they face a daily struggle just to survive. and that's where this week's "cnn hero" comes in. he's an australian who moved to vietnam and now gives street kids a chance for a brighter future. >> here in hanoi, kids come to the streets hoping that it will be better than living in poverty in the countryside. but often they find things are much worse for them here. you can actually identify kids who are living and working on the streets. they may get detained by the authorities. they may get beaten up. there are ng ga gangs selling h. we find kids being tricked and sold into prostitution. it was just a case of i can help, so i should help. my name is michael. i work in vietnam with street kids, trying to get them back into school, off the streets and into safe homes. when we started out, our goal was to just to get them back to school. to do that, we realized we would have to take that place of providing an income, food, providing the shelter. our center is where the kids know to come. this is where they feel safe. they can join in our activities. they can talk to the staff. and then we've got to make sure they're working towards education or getting a job or improving their health. we've also got to be careful that if the child has a family, the family is as involved as possible. it's an amazing feeling, getting to watch these kids go from being malnourished and just completely lacking confidence to wanting to make a change. i grew up in poverty. and i often used to think i could do something with my life. if only someone would come and give me that chance. now i'm the guy who can help these kids and give them a chance. >> since 2004, michael and his blue dragon children's foundation have helped more than 350 vietnamese kids get off the streets and into safe homes and schools. remember, "cnn heroes" are chosen from people you tell us about. so to nominate someone you think is making a difference in your community, go to cnnheroes.com. a record flood moving slowly down the mississippi. we'll check in live with our own rob maurs yarciano in greenvill. what do you got?
