spring rains and melting snow. in iowa there's word of a levee breach along the missouri. right now fortunately no reports of any damage or injuries. in arizona, the complete opposite. disaster brought on by flames. several big wildfires burning across the state. right now they've scorched more than a quarter million acres. hundreds of people have been told to pack up and get ready to leave. >> my heart just simply goes out to them and i want them all to know that certainly they are all in our prayers and that we hope that god protects them and -- and their homes and their communities. it's a very tragic situation that they're facing. >> smoke from the arizona fires is affecting air quality in neighboring new mexico. floods, fires and a heat wave. jacqui jeras stris tracking all

them for us. >> we'll start out with fire conditions. unfortunately the weather is going to make things worse there especially as we head into tomorrow. we've had extreme fire behaviob. see the flames grow and how much smoke has enveloped this area. hundreds of miles that smoke has been traveling. we have critically low relative humidity. we have high winds. they've been gusting as much as 35 miles per hour. and the temperatures are very warm as well. when we think about arizona, martin, we think about desert. we think about cactuses. but take a look at that. there are a lot of pine trees in here as well as the scrub. there's a lot of fuel for these fires to continue to burn. there's an area of low pressure, a storm system offshore off california's coast. this is going to be heading up to the north of arizona. unfortunately we don't think it's going to bring in much in terms of relief with rain and showers and thundershowers. but it is going to be increasing the wind. so fire weather watches have been issued across the area for tomorrow as those conditions are

expected to get worse as well. the heat has been a big story. not just in the southwest but really looki ining at the deep south. the heat indices well over 100 degrees in some of these areas. that's going to continue. hot weather, dry weather all continuing. we'll continue to monitor floods in the missouri river as we know the missouri dumps into the mississippi. we'll have to see what kind of impact that's going to have in the weeks and months ahead. >> if only they could divert it over to arizona, we'd have a solution. in other news, they say bean sprouts from central germany likely are the cause behind the e. coli outbreak across europe. at least 22 people have now died and more than 2,000 have become ill. so far that infection has not spread to the u.s. but here's what you need to watch out for. >> well, it comes from three main places for a consumer. number one, it's often present on meat, raw beef particularly. make sure you cook those hamburgers properly, especially as we're heading into the summer season. second risk is on fresh fruits

and vegetables. make sure you wash them. if they come already washed, you're fine. if they've not been washed, wash them. if you can peel them, peel them. the third area of risk is milk. make sure the milk you drink is pasteurized and not raw. >> even though they have a likely cause, european officials are warning the e. coli outbreak may not be over just yet. anger and violence bubbling over in the middle oost. the border between syria and the golan heights. israel says that it fired warning shots to push back the crowd but a report on syrian television said 25 people were killed. more than 300 were said to have been hurt. then to yemen where there is a lot of uncertainty surrounding that country's president. ali abdullah saleh is in the hospital following an attack on

his palace. there's question about his injuries and when and if he'll return to yemen. there's start with the medical condition for the president. what have you learned? >> marty, we do know that president saleh was seriously injured in the attack on his palace on friday where not just he, but his prime minister, deputy prime minister and speaker of parliament were injured. we understand the president suffered severe burns and sla shrapnel wounds from the attack. >> the question may be answered i guess by how he does medically. still, is this a temporary leave of absence or permanent? >> well, as of now it's a temporary absence and he's handed over power to his vice president, abdul rabidhami. just like in the united states if the president was undergoing a medical procedure he would hand over to the vice president. really this is all about whether

president saleh is going to stay outside the country. there's been a lot of pressure on him to sign an agreement brokered by saudi arabia and the gulf cooperation council which would pave the way for him to resign and elections in 60 days. we've seen a lot of violence in recent weeks which led to that attack on the palace yesterday between rival troops of the main tribes against him and also with government troops. so a lot of violence. saudi arabia, the united states really trying to make sure that he doesn't go back to yemen and that they start a process of transition. >> yet there was a cease-fire that was apparently brokered today? >> we understand the vice president did offer a cease fire to the troops. apparently they accepted. they're starting to withdraw their troops from some of the government buildings they've been occupying. this is really interesting, marty. we've seen throughout this ash spring that a lot of these protests were very peaceful. youth, students, activists out

in the streets. that's what started in yemen. then this became more of a civil war in the making between rival troops that are trying to get president saleh out. the vice president wants to stop the violence and deal with the issues of reform. if president salel stays out of the country this would trigger elections in 60 days. >> what's the u.s. attitude? >> the u.s. is obviously working this very closely with the saudis, gulf cooperation council. john brennan, the adviser to president obama, was out in saudi arabia this week trying to get president saleh to sign this deal. the u.s. wants president saleh out. they stood by him for a really long time because he was an ally in the war on ter. >> reporter: this presents an opportunity for al qaeda and extremist groups to exploit the vacuum in the country. this week secretary of state clinton was as emphatic as anybody has been around yemen saying it's time for president

saleh to get out, move out of the way for a transition to democracy, marty. >> i want to turn the corner real quick while we have time to talk about libyan. new developments on the libyan woman who was allegedly gang raped by moammar gadhafi security forces. what have we learned in the new information about her whereabouts? >> this poor women really hasn't been able to get a break. not only after she was claimed that she was raped by libyan forces, then they detained her. she finally escaped to tunisia and on ward to qatar where she was deported back to libya. we understand she has made it out of qatar. she's on her way to mull ta and europe for processing as a refugee status. secretary of state hillary clinton has taken a personal interest in this case and has helped try and get her out of the country. she'll be on her way to europe for processing as a refugee and on ward to a third country.

we've heard she wants to come to the united states. the u.s. isn't saying anything. usually doesn't about asylum cases like this. but we do expect that she'll be in europe and then will be resettled somewhere, possibly the united states. >> thanks very much for the insight. we'll talk to you again. here in the u.s., dominique strauss-kahn is due to be arraigned in a new york courtroom. that's expected tomorrow. the former head of the international monetary fund is expected to plead not guilty to sex crimes charges. a hotel maid has accused him of trying to rape her lant month. skrausz kahn was released a multimillion dollar bond and ordered confined to a secure apartment. well, expect to hear more expert testimony tomorrow in casey anthony's murder trial that resumes in orlando. yesterday there was a forensic scientist who testified that hair taken from the trunk of the defendant's car was similar to that of anthony's daughter, caylee. she was reported missing three years ago. then, of course, later found dead. many businesses are looking to expand.

toronto, san francisco and chicago. here now the top two. los angeles is a surprise and houston. in our financial fix today, many grandparents with extra cash in the bank are gifting it to their children and grandchild. it benefits more than those on the receiving end. financial adviser karen lee tells our richelle carey how it all works for the giver. >> you've got extra money and you want to give it away. you might have a financial adviser or an estate attorney telling you, you need to reduce your estate. but mostly what you'd like to do is give that money while you're alive versus waiting until you die. >> okay. >> that's the why people give. now let's talk about what you can give. >> right. okay. >> be strategic about it. >> of course you can just write a check. first let's go over the rules. every donor is allowed to give up to $13,000 a year to any amount of donees.

if it's a married couple that's two donors. that's $26,000. the number of donees they give to is unlimited. if you need to reduce your estate, you can do a lot there. they don't have to be related to you. but generally you're going to see grandparents gifting to grandkids and my favorite thing for them to do is look at their portfolio, and if they have stocks that they bought 20, 30, 40 years ago and they're highly apprecia appreciated, they don't want to sell them because there's all those capital gains, gift those shares in kind to your grandkid. because if you are single and earn under 34 grand a year you're in the 10% or 15% tax bracket, you pay no capital gains. >> that makes a lot of sense. >> that's my favorite thing for them to do. >> okay. you also -- how do you go about doing this? >> basically, what's the best way now. i'm determined what i'm going to give and how much and to who. where should i have them put it?

the one thing that's pretty common is what's called utma. uniform transfer to minor act. replace the ugma uniform gift. that's an irrevocable gift to a minor. it becomes theirs for any use at all at majority age which here in georgia is 18. in some states it's 18 or when you graduate high school, whichever is later. there's, like, two states that it's 19 still. so that's popular. child can use it for anything. what i love personally is the 529 plan. >> very, very popular now, aren't they? >> they are. they encourage the kids to get higher education. because if you use those funds for college, technical schools, i believe, too, then all the gain in the investment you get tax free. >> wow. >> right. >> very good. >> but there are penalties if you don't. so it encourages the kids. so i like that one. there's still savings bonds -- >> the good old fashioned way. >> they've always been

considered the safest because they're backed by the u.s. government. i think that might be a little bit questionable these days. just a little bit. the interest on those if used for college, also tax free. then, of course, just an outright gift. write a check. >> you can catch financial fix every saturday at 2:00 p.m. that's eastern time. on sundays at 4:00 right here on cnn.

something in a regular school and you don't get it but you take the test and you get a c on the test -- >> can't move on with a "c" here. >> that's right. >> richard julian is a fifth grade teacher in california he uses kahn videos in math class. the software tracks each student's progress. >> by doing that it allows the teacher to know their students very well. it allows them to know their strengths. it allows them to know their weaknesses. >> kahn academy is a nonprofit. it's backed by bill gates and google. you're doing this for free, partner. >> if kahn academy was for a profit it would limit the number of kids that will use it. hopefully when i'm 80 i can say, wow, there's a billion kids that use it and maybe will continue to use it. >> reporter: steve perry, california. the economy is still struggling, but some careers are making a comeback. and with fatter paychecks. take a look at the list from careerbliss.com. which job is the comeback king?

before the break we listed some of the comeback jobs of 2011 and asked which was the comeback king. the answer? according to careerbliss.com tax

specialists saw their average career salary spike from 2009 to 2011 from $20,000 in 2009 to $39,000 today. a bleak job report out friday showing the employment rate is over 9%. what can experienced workers do to try to find that job that may be eluding them? the author of "get a life, not a job" joins us. let's talk about what can you do. how should you get that job? >> right now, martin, the most important thing is skills. skills are king. having great skills that match up to what employers need and then getting through those barriers to entry like the interview and the resumes. right now most important thing, get great skills. try to configure your skills to jobs that are open. most important. >> how do i do that, though? if you're a person in your late

40s, 50s, you've made most of your life doing something else, someone says get great skills, how do i do it? >> there's opportunities for training and education at any age. i'm a strong advocate of job retraining and education. real important thing, though, before you spend any money investing in tuition dollars, be sure you understand the placement rate for the program that you're about to invest your time and yur money in. even though you might be in your 40s and 50s not too late to reinvest in time and talent. the other thing you can do is think about configuring your skills for hotjobs. a wonderful website from the department of labor, great opportunity to look for jobs that really match with your skills. ones that are really hot right now. >> you mentioned targeting your educational investment. by that i presume you mean make sure you find the hot job before you actually invest your time in learning about the job.

>> absolutely. right now, martin, the stem skills are always so hot right now, right? science, technology, engineering, math. the class of 2011, interesting. the class of 2011, if they went to reputable schools, those who graduated with the stem fields, they were able to land multiple job offers and their starting salaries were between $55,000 and almost $70,000. these are 20, 21, 22-year-olds. not a lot of experience, but they had great skills. so s.t.e.m. skills real important. also the skilled trades. so carpenters, engineering, plumbers. those are also in very, very high demand. health care also very important. but also think about education. again, science teachers, math teachers, real important. bilingual education. also those who can teach special needs children. all those are real hot and will be hot for a while. >> you talk about, say, take a temporary job or maybe even a

volunteer job? the reason being, of course, what? you get your foot in the door? >> you get your foot in the door and i know this is really tough to hear at a time when people feel like they're underemployed, those who are working part time or working in temp positions. but it's a nice way to get your foot in the door and to network within the organization in case something should become available. what we found, again, class of 2011, those who had internships, so those who were on those temporary interning positions, 67% of them were offered full-time jobs. so temporary opportunity turned into a full-time one for those interns. real good strategy to break in. >> as my mom always tell s me, you know, it's not who you know, it's who knows you. this goes back to what you just said. networking, networking. very important for people to get out there, meet greet and talk to folks who may have a job. >> right. networking, always critical. so networking online. networking in person. also, too, thinking about

networking, if you do end up engaging in an educational opportunity, network with your professors. network with the trainers. network with fellow students. network with guest speakers. network with alums. lots of people are interested in connecting with you. but oftentimes students and those in training programs don't actually leverage that part of their investment. real important to network. >> author of the book "get a life, not a job." good advice for people who are having a hard time. the republican presidential field is getting a bit more crowded. we'll tell you who is about to enter the race next. ♪

[ male announcer ] wells fargo. the republican presidential field is about to get bigger. rick santorum will announce his candidacy tomorrow. the former senator will throw his hat into the ring in a rally tomorrow in pennsylvania. we're going to talk you about rick santorum next hour, teasing ahead. this hour, let's start with the republican candidate who's not exactly conventional. ron paul. let's listen to what he had to say this morning on cnn's "state of the union." >> we don't have democracy in this country. it's so biased. if you're a third party, i can't

get in debates as a third-party candidate. what i did as a third party, spent over half my money just trying to get on the ballots. we don't have a good democratic process. what happens if you come to the conclusion the parties aren't different. they're the same. monetary policy stays the same. welfare stays the same. foreign policy stays the same. there is one party. people who want to participate, they more or less have to get into one of the major parties. >> you know, mark, i hear that complaint from a lot of people when i'm out in the field and they want to talk about politics. does he have a point? >> he does have a point in the fact that there really are only two parties. the democratic party and the republican party. if you want to run for president and you want to have a shot at winning as you run for president or any elected office, you have to join one of these parties. and when you hear ron paul there saying that, he himself is acknowledging he doesn't agree with the republican party on

many issues. yet in order for him to run for president, for him to be taken seriously he himself has to conform. >> then we also know that ron paul is a republican, but he certainly has a libertarian philosophy. do unconventional candidates like this have a real chance of winning the nomination? >> unfortunately, no. not at this point. what we've seen over the past couple of years is that they can start to steer the conversation. you know, just a few hours ago when he was on "state of the union" he talked about how back when he ran in 2007 and 2008, he talked about his opposition to the wars in afghanistan and iraq. he talked about his opposition to this out of control federal spending. these are two issues that we are starting to hear from republicans as well as some democrats right now who are pretty frustrated with the way washington is working. but by and large, if you want to win, if you want to be taken seriously, you have to be part of the main political operation, whether it's the democrats, whether it's the republicans, martin. >> let's turn the page real quick to john edwards. on friday he pleaded not guilty

to conspiracy and campaign law violations. you covered his campaign when he was running for president. to many of us we're shocked by the turn of events. i'm wondering what your take is. >> yeah. you know, even before he became this national figure, martin, i covered him when i was a reporter up on thrill. i remember about six months after he was elected, remember, he really came on the national scene as our viewers will recall when he gave this impassioned speech in defense of bill clinton on the senate floor when the articles of impeachment had been sent over to the senate. so he was considered this rising star in the democratic party. he had come out of nowhere. but i remember sitting across from him, martin. he talked lovingly about his wife, elizabeth, and how she was such a driving force in his life. and, you know, he was very -- i wouldn't use the word timid. but he was very reserved in about what he thought his future was. well, things have changed, obviously. they changed very, you know, quickly when he was in the senate. then, of course, we find out that he had an affair and really what i think is frustrating to a

lot of people, certainly people who worked on his campaign and people that i've spoken with, is that they're just very disappointed with him. in many ways the word "disappointment" is probably the worst word you can hear from somebody. because they feel like john edwards had so much potential, that he could have done so many good things for the democratic party. not only did he rip apart his personal life, in some ways he potentially could have ripped apart the democratic party had president obama chosen him to be his vice presidential running mate. not a lot of sympathy for john edwards nowadays, martin. >> no. mark preston, thanks very much for joining us. for the latest political news, you know where to go. cnn politics.com. it is his last trip to afghanistan as the u.s. defense secretary. robert gates spoke to u.s. troops today in kandahar answering questions about the war and this summer's withdrawal of forces from afghanistan. then it got personal. >> i just want you to know i

there is a revolution taking place in the war of cancer. people are both surviving at much higher rates and living with the disease longer. dr. bill lloyd joined our richelle carey from chicago yesterday where he was attending the world's largest meeting of cancer treatment specialists. he offered five reasons for the latest successes in the war on cancer. >> without painting too rosey a picture, it is cancer, after all, but since 1970 there's been a four-fold jump in the number of cancer survivors in just four decades, which is an enormous growth. if you look at the ten-year survival for different cancers they're equal to what used to be five-year survivals. people are not only living longer, they're enjoying better lives even though they have cancer. richelle, patients now have more options than ever before. >> dr. lloyd, tell us what some

of the weapons are in the war on cancer that are helping us make these improvements by leaping and bounds. >> let me tell you about five powerful weapons that weren't here just a few years ago. the first one is the internet. it's allowed researchers to collaborate and work together like never before. for patients, they can use the internet as well. i recommend clinicaltrials.gov to find out about the latest research in fighting cancer. also in the past we used to go after the entire organ that had the cancer. it involved a lot of surgery and damage to a lot of healthy tissue. now we use critical targets. we go after specific cancer cell and spare the rest of the healthy body. the discovery of biomarkers. these are small strips of protein. they're like a license plate. they help us target specific areas where we want to treat the cancer and sparing the healthy tissue. we call this individualized medicine. selective radiation. instead of burning an entire lung and damaging other nearby tissues, technology allows us to

target the specific area that will benefit from that radiation therapy. finally, there's a variety of buy logic tools that are available to boost the body defenses. even vaccines made from the patients' own tumor cells. >> some of the strategies do not involve always directly attacking and killing the tumor. talk about some diseases that have benefited from that particular advance. >> sure. sure. what we were saying before, of course, you got a diagnosis of cancer, you're going to have mutilating surgery, lots of radiation. then we're going to poison you with chemotherapy and outcomes weren't good. now with the select individualized therapies, many cancers are experiencing remissions, recoveries and even cures like never before. we talk about diseases like cancer of the liver. leukemia and nonhodgkins limb foe ma at the top of the list. many thousands of americans are diagnosed with these conditions every year, these three important cancerings.

to me now. >> fear spread throughout communities because so little was known about the disease. can france cisco general hospital became a model for aids car. in 1982 dionne jones worked in the aids ward. >> we were in this mentality to prove to the rest of the world it was the right thing to do and safe thing to do. >> reporter: despite years of advances, the stigma is still there. >> what's still happening, if i sit down like i did recently and tell somebody they're hiv positive, they're still reacting in the same way that they did 30 years ago. i'm going to die. i can't tell anybody. >> reporter: norman tanner cofounded black brothers esteem, helping to push african-americans to get tested. tanner himself was diagnosed in 1990. >> they're scared of the unknown. they're scared of the unknown. but they have to realize that we are living longer. now it's about hiv and ageing. >> reporter: the world became familiar with the drug azt which

if they represent the status quo and nothing i believe in, but who knows how things may evolve. >> there are two dynamics that have changed the political landscape. the power of the internet as well as the citizens tea party movement. those dynamics neutralized as having the most amount of money. we'll have enough money to be competitive but we don't have to have the most amount. >> those candidates are about to get more competition. republican rick santorum will announce his candidacy tomorrow. cnn political editor mark preston joins us from washington. what do we know about santorum and really what do we know about his chances of success in this race? >> rick santorum lost re-election back in 2006. but he sees this as an opportunity to perhaps get back in the national spotlight. rick santorum is hoping, what i'm told from people very close to him, to present himself to be the most
