we have now, yesterday we were thinking there wasn't going to be a referendum. now the greek finance minister has told the eu there will be no referendum. but as you alluded to, within about six hours or so there is going to be the final step in a confidence vote on the greek -- in the greek parliament. the prime minister, george papandreou, who's really behind all the drama this week, only has a two-seat lead in parliament. so it remains to be seen what's going to happen in greece. but randi, greece is a tiny country in the grand scheme of things. it is the 32nd biggest country in the world in terms of its economy. t italy is a much bigger country and italy right now is in the focus because right now lenders from around the world, whether they're banks or governments, are looking at europe and saying is this a stable organization? are these 17 countries that use the euro trustworthy that they'll pay their debts? after what we saw with greece they are starting to look at italy now and say there might be more risk here than they first thought. so people are a little more relaxed than they were this time, randi. but they're still pretty much on edge. >> yeah. i would say for our viewers, ali, some perspective from the president, a glass half-full prif, if you will. let's play that. >> make no mistake, there is more hard work ahead and more difficult choices to make. but our european partners have laid a foundation on which to build and it has all the elements needed for success. a credible fire wall to prevent the crisis from spreading. strengthening european banks. charting a sustainable path for greece. and confronting the structural issues that are the heart of the current crisis. >> so ali, you listen to that, but really when i think about it, doesn't a whole lot still ride on what the greeks decide? >> reporter: i would say president is overstating the case a little bit. what he's saying is what he hopes happens. the reality is there's no fire wall around europe at the moment. they're talking about beefing up the international monetary fund. greece is the biggest recipient of money from the international monetary fund right now. it's more hopeful talk. one of the things is that even though we've seen this sort of debt debate in the united states, the key bates goidebate greece go on everywhere but europe is not a federation, they don't have somebody who makes those decisions so the biggest thing that happened this week is on wednesday, sarkozy and merkel, of france and germany, called papandreou, who's not a member of the g-20 to cannes here and told him, if you do this referendum and it goes the wrong way, you might get kick out of the euro. that's probably the biggest accomplishment this week. there's finally a rule that says if you do something that fundamentally affects the euro and the other countries in it, you might actually get kicked out. that's obviously the biggest take-away this week. >> thank you, ali velshi, very much. nice to see you as well. whether it is a g-20 jitters abroad for jobless worries at home, investors are in a funk. the dow, nasdaq, s&p all down more than 1%. right now blue chips are down 145 points there. the big concern here is a small report from the labor front. we learned this morning that u.s. employers added 80,000 jobs last month which isn't terrible but far less than needed. the jobless rate actually fell .1 point to 9%. but almost 13 million americans still looking for work still cannot find a job. deliberations now under way in the involuntary manslaughter trial of michael jackson's doctor, conrad murray. over the course of 23 days the jury heard from 20 witnesses, and the prosecution argues that the evidence is "overwhelming," while the defense maintains it was the acts of jackson himself and not murray that led to his death. stay with cnn. word of a verdict could tomorrow at any time. the hemp hadden cain campaign is said to be mulling a lawsuit against the online news site that first reported sexual harassment allegations from the 1990s. a campaign spokesman tells cnn that nothing's been decided but a suit is being discussed against politico.com which for the record stands by its reporting. we're also waiting to find out whether one of cain's accusers will be allowed to put out a statement giving her side of events that led to her departure from the national restaurant association which cain at the time headed. the sexual harassment storm surrounding campaign continues. his camp blames perry's camp but rick perry says no campaign leaks here. >> no apology needed. we found out about this the same time that i suppose the rest of america found out about it. >> john king joins us live with more on this republican blame game. but first, i want you to meet today's rock star. kelly slater may be the greatest athlete you never heard of. he just captured his 11th surfing title in san francisco giving him bragging rights to being the oldest 19 years ago the youngest to ever hold this title. pretty amazing work there on those waves. my producer, kelly, thinks he's awfully cute. smokin' hot, think were her exact words. kelly slater, total rock star. ♪ back now to the drama surrounding what is still a top tier republican presidential campaign. that, a former restaurant executive and radio talk show host herman cain. one would think cain had a pretty dismal week giving inconsistent answers to sexual harassment questions that haven't exactly gone away. but poll numbers, fund-raising and grassroots recruiting would seem to show otherwise. my colleague john king is watching all of this from his post in iowa. hi there, john. let me ask you first, what do you make of this potential lawsuit against politico? can and should a presidential campaign try to sue over bad press? >> anybody can sue anybody in the united states of america. i view it as a bit of a stretch and i think it is part of the reaction of the cain campaign to push back to try to get people to rally around him to perceive him as somehow a victim here. would you have to prove -- randi, you know the business we work in. they'd have to prove some malice or intent, some libel. politico says mr. cain himself has conceded there were settlement so based on everything i know today i would say it is a legal stretch and a big legal stretch but it is part of the political debate i think more than any legal debate. as you know, john, herman cain isn't just sore at politico, he's also pointing some fingers at rick perry's campaign. you sat down with rick perry yesterday. what did he tell you? >> rick perry was here in iowa. his campaign has been struggling as well. the last thing he needs right now is some character questions. herman cain is saying it was rick perry who did this to me. when i sat down with the governor yesterday i asked him point-blank, has he asked around his campaign and governor perry says it wasn't him. listen. >> the cain campaign and the candidate himself say that you and your campaign owe him an apology. do you? >> no apology needed. we found out this about the same time i suppose the rest of america found out about it, both on the internet or the next day in news. so i don't know how to tell any other way except knew nothing about it, sir. >> you think does mr. cain owe you an an poll gi for pointing the finger at your campaign. >> there's going to be more stuff floating around there in campaigns. as i tell people, this isn't my first rodeo. they're going to say all kinds of things about folks. i'm going to stay focused on how does america get back to working an we've laid out a couple really good plans both on the energy side and the tax side and how to cut spending and that's what americans are interested in. >> it is what americans are interested in. unfortunately, as you know, because it is not your first rodeo, campaigns sometimes do get distracted by these things. just lastly on this point, there have been some in your campaign when we call about this who say it is not us, but maybe you want to look over at ramny land. is that fair? >> look, again, i'm focused on my campaign on the issues that are important to the people and i'm -- this is over. it is gone, done with and i'm pressing on. >> one other thing. he did say he was certain -- he said he was adamant about this -- that no one in his campaign did this. i asked him what if you found out down the road before somebody was responsible. before i could answer the question, he said out the door. he said anybody who would leak what he called hellacious material would be fired. he isn't happy to have the finger pointed at him as as you heard he very much wants to move on and talk about the economy and other issues. >> i'm sure he does. herman cain would like to move on, too. but with all that's going on, it doesn't seem to be hurting his fund-raising. still neck and neck with mitt romney according to recent polling. >> one of the reasons we're happy to be in iowa at this time is we wanted to get a sense right here at the grass rights. iowa votes 60 days from tonight, the first vote that counts in the republican nominating contest. herman cain is tied for the lead near sta pit with deep support among evangelical voters. listen to steve grubbs, a veteran and the vis. is this hurting? mr. grubbs says no. >> we measure the impact by what the voters are telling us and what i know is last week we were signing up 25 to 30 precinct captains a day. right now we're signing up 40 to 50. fund-raising's up. the overnight rasmussen poll since cain's still leading the pack. right now early indications are that herman cain is weathering this storm. >> weathering the storm. early indications. this is "the des moines register" op-ed page today, one of the papers columnists saying cain should fess up to what happened. there's media criticism or at least questioning here as well at the moment. at the moment we see no immediate impact. if you look at polling and deep in it you do see some concerns among republican women, so we'll have to watch this over the next several days. i just had a conversation with the form he pennsylvania senator rick santorum. woe very much like to pick up that evangelical support mr. cain has right now. rick santorum says he's had 20 town halls across this state in the last five days. the last five days we've been talking about these allegations against mr. cain. 25 town halls in five days. rick santorum says not one comment or one question about herman cain. >> wow. i'm sure he'd like to get a little attention about those town halls. john king, thank you. they line security checkpoints at airports across the country. the dreaded poddy scanners. first there were privacy complaints. now cancer concerns. what you need to know about those body scanners.

[ male announcer ] listerine® total care. the most complete mouthwash. we've all been there -- the security checkpoint at the airport. and there it is -- the dreaded body scanner. we fussed, debated, complained and quite frankly, raised hell over the issue of privacy. but what if i told you those ex-ray body scanners may increase your risk of cancer, that the u.s. government may be knowingly exposing passengers to radiation levels considered unacceptable by many experts justifying it with their efforts to stop terrorists. that's just part what have was cover uncovered in a troubling pbs journalist. michael graybell joins us, along with the executive vice president of rapiscan, the company that manufactured x-ray body scanners that you see in the airports. welcome to you both. a lot to cover here. michael, you say in your report there are two types of scanners being used at u.s. airports. there are currently 250 x-ray scanners and 264 millimeter scanners that use radio waves. the secure 1,000 is the x-ray scanner which emits low doses of radiati radiation, but in your report, michael, you go on to say that the government is rolling out x-ray scanners despite having a safer alternative that the tsa says is highly effective. the safer alternative is this scanner, which uses low energy radio wave. why not just use the safer alternative everywhere? why is the government rolling out the riskier, as you call them, x-ray scanners? >> we asked the tsa this and they say, it is important to note this is an extremely low level of radiation so the tsa says that small increased risk you might get is outweighed by the security benefit that you'll get from these machines. the second thing that they say though is that they want to increase competition to try and build a better mousetrap. by having multiple technologies in play, they allow companies to try to improve the detection capabilities of the machines. >> mr. khan, i'd like your response to the report that says your x-ray scanners increase cancer? >> i think this report based on no real science. the technology we've made has been tested over a decade by independent third party experts who know about radiation safety and x-rays. every single one of those tests on the actual system have reinforced that it is safe. the report is based on six scientists who haven't done any of that analysis, never seen a system, never even asked to see a system and did it on paper with math. it is just not true. >> i want to share with you a statement we just got in a moment ago from the fda on this. they're saying that since general use x-racist terms emit ionizing radiation, the societiable benefit of reliably detecting threats must be determined to prevent a risk. the dose from one screening with a general use x-ray security screening system is to low that it presents an extremely small risk o tony individual. the head of the tsa says the agency plans to perform a new independent study on these new body scanners. you also say there was a big swing from the x-ray machines be considered taboo to all of a sudden being safe enough to scan millions of passengers. who you did we get there? >> sure. back in 1998 an fda advisory panel looked at these scanners which at the time were only being used in prisons and the outside medical experts said, we have a lot of concerns about these seeing widespread use, especially being used to the traveling public. and at time and this is a long-held thing in the medical community -- you don't x-ray someone unless there is a medical benefit to doing so. we've certainly seen a growing concerns and increases in attempted attacks and attacks in russia people kind of carrying explosives on to airplanes. that's how we got here but at the same time these machines are classified as electronic products. not the same as the medical x-ray you might find at your doctor's office or hospital. another thing we say in the report, there is no cause and effect to re-assure you, but coincidentally at the same time, rapiscan did increase its robbying efforts from 2006 to 2008 to get its message across, tripping its expenditures, opening plants in the districts of key lawmakers or expanding plants and also hiring key legislative aides to those decision makers. there mr. khamp, i'd like you t respond. >> we've grown our business since 2001 and since we've been in business for over three decades. of course there is more government spending on explosive detection equipment. in fact most of our government funds come from the u.s. military for protecting u.s. troops and soldiers in afghanistan and iraq. so rapiscan certainly needs to spen time talking to lawmakers and policymakers primarily to overtime the misrepresentations and miscommunications and misleading statements such as the one in the article that these systems were unsafe. >> i want to also ask you, mr. kant, why doesn't your company try and make what many consider to be the safer technology? >> we at one time did provide millimeter wave technology. actually uses microwaves. how it is considered safer, don't know. it's never been tested for its health effects. these are microwaves. some are what's used in cell phones and microwave technology. a record from the world health organization questioned the safety of this kind of technology. of course it's never been tested. ours has been tested. and the reason why we use the scanner technology is it provides the highest level of detection with the lowest false alarm rate. so unlike recent tests of the millimeter wave technology in europe which were canceled because of lots of false alarms and lots of people were still getting patted down after going through the system, our system doesn't create those problems. it is faster for passengers and it is easier which is why we've seen in europe and in the united states over 95% of people polled by governments and polling agencies at airports prefer this process to a pat-down. >> we reached out to the fda and tsa. the tsa said, back scanner technology is safe for all passengers and it is ekwifb lent to an amount of naturally occurring radiation received during three minutes of flying at altitude. michael, in your reporting what do you make of this when you see a state like that? >> i want to point out, this isn't six rogue scientists. is ionizing radiation which we know damages dna and increases the risk of cancer. the national academy of sciences has looked at this -- has looked at the issue of low levels of ionizing raid yag and said there's no low level at which the risk -- at which the risk of cancer is zero. so while it is a very small amount relative to the amount of people who get cancer on an annual basis, there is a slight increased risk looking at two reports that were done, these are -- i don't know there have been many more than that that have been done. one estimated six among the 100 million passengers to travel every year and one estimated as high as 100. if you were to consider that we're coming close to 1 billion people traveling through our airports every year. >> mr. kant, i'll give you the final word on this. >> that's just an embarrassing use of poor science. the situation is you got five times more radiation from drinking a sports drink when you work out or more -- almost 50 times sleeping next to your spouse at night. talking about low level radiations as major cancer risks is ridiculous. >> all right. thank you both for coming on. think this is a really important story and certainly doesn't get enough attention. i think the public is certainly very curious about what these machines are all about. so thank you to you both. appreciate your time. it all comes down to seven men and five women. dr. conrad murray's fate is now in the jury's hands. michael jackson death trial coming next. but first, on this day in 1979, islamist students and militants stormed the u.s. embassy in tehran, starting the iranian hostage crisis. 52 americans were held captive for 444 days after multiple failed negotiation attempts. the group took over the u.s. embassy in support of the iranian revolution and that is this shame in history.
