we begin with the latest on an in-flight scare that forced a u.s. jet to make emergency landing by fighter jet. it raises fresh concerns for security for airliners headed to the states from africa and europe. u.s. airways flight 787 from paris to charlotte diverted to bangor's maine after a passenger's note warned she had a surgically implanted device. the plane with 188 people on board landed safely and the woman else courted off in handcuffs. officials determined she didn't have a device after all but that leaves plenty of questions. fran townsend is with us, a member of the external advisory committee for the cia and department of homeland security. fran, this is something people have been worried about, somebody with an implant device, perhaps a bomb. >> we saw an aggressive response because what we've heard for months from intelligence and law enforcement sources that they're really worried about this because they heard this threat stream. this goes back to yemen, the al qaeda in the arabian peninsula. the bobmaker is al siri, responsible for the recently foiled plot we've heard so much about, and this is a device, we haven't seen it happen yet, haven't seen an implanted device explode but we know from the 9/11 commission not to have another failure of imagination so they take this threat scheme seriously. they saw no evidence of recent surgical marks but couldn't take the chance they missed something and scrambled two f-15s and put it in bangor, maine, which is consistent with what the protocol would have been with a flight coming in with a threat from europe. >> is there anything turns out not to be the case, no recent surgical marks but if you're the crew on that plane i assume you have basic guidelines if somebody says they have this, you have to assume it's serious, correct? >> that's exactly right. we understand now that they put her to the back of the plane, where she was examined, she was held there. the pilot then notified the air traffic control and they did do exactly what they've been trained to do, and john, while this turned out to be a woman with sort of a false threat, they didn't know that in the air and did everything they were supposed to do to protect the passengers on that flight. >> since this threat it out there and we assume this say false alarm and they acted appropriately, where are we in terms of getting to the point can the devices be detected? >> well this is probably the most difficult challenge we're facing. there's no one single silver bullet that would have detected this. what tsa i think tells us that they rely on is a matrix, a multilayered approach. so you go through, there are screeners who have behavioral training to spot anomalies. they swipe your hands and you go through back scatter and millimeter wave machines. what the hope is that this multilayered approach would allow them to identify somebody that was an anomaly, so they might be able to detect it but right now there's no single screening device that would detect an implanted device. >> fran townsend, thanks. >> thanks, john. we're tracking a potential break-through on iran's disputed nuclear program. the united nations nuclear watch dog says expect a deal in the next few days which could clear for fuller access to controversial sites and scientists many people could be part of an atomic weapons program. >> last time i said progress was made. this time i'm saying decision was made. >> nick burns is the former undertear of state former ambassador to nato and now teaches at harvard university. is this a break-through or another iranian promise soon to be broken? >> well it's one of the two, john. it could be a break-through but we have to see the details of this agreement, if it's finalized by the international atomic energy agency. we've learned with the iranians over the last several years you cannot trust and you have to verify, and this deal, of course, that's now being reported in the press is by no means finished but it is a good sign that they invited the chairman of the iaea for the first time in a couple of years to visit, that they're talking about much more intrusive inspections of suspected nuclear sites, and of current nuclear sites. that's been one of the big issues that the united states and other countries have had with the iranians, their refusal to allow the iaea to monitor exactly what the iranians are doing and of course, john, this coincides with a very important second round of negotiations tomorrow in baghdad, where the united states and the other members will be negotiating with iran. it looks like there's momentum towards at least the beginnings of some agreement but until we see the details, we have reason to be cautious. >> you say reason to be cautious, the israelis are openly skeptical, they have the most at stake you might argue. they believe what iran is doing is agreeing to some technical agreement on paper so they can go into the talks tomorrow and say back off the sanctions, give us a break. should the p-5 plus one, the group that it's called, the united states, should they back off or ratchet up the pressure? >> i think the iranians are at the table in baghdad tomorrow because of the pressure, because of the sanctions, so i would think that we'd want to see a maintenance of the sanctions, if not a reinforcement of the sanctions, and indeed, the eu oil embargo in iran is just now beginning to be implemented and the u.s. central bank sanctions which are so important also just beginning to be implemented. so i'd be surprised if we saw the sanctions taken off iran, because i think that's been the reason, that's what's motivated the iranians, that and force fr israelis, made credible by the toughness of prime minister netanyahu. those are the two reasons why the iranians appear to be moving. . >> former nato ambassador undersecretary of state nick burns thank you for your time tonight. >> thanks, john. let's turn to an important consumer safety story here at home. the stroller brigade invaded capitol hill today. a group of mothers pushing their babies and pushing lawmakers for a crackdown for dangerous chemicals found in everyday products. here's dana bash. >> reporter: strollers, babies, breast feeding pillows, usually women walking around the capitol like this are tourists, not activists. >> hey, hey, ho, ho, toxic chemicals have to go. >> reporter: moms like lisa allen came from all over the country to push regulation of carpets in items for babies that could be health hazards. >> as a mom it's overwhelming. we do the best we can but we still need help and hoping that our senators will help us to protect our children. >> reporter: flame retardant chemicals in many carpets and couches pushed by the smoking industry to prevent fires are toxins that could cause cancer, fetal impairment and fertility problems. that prompted this protest. >> every time you sit down on the couch, you know what happens? when you sit down, you release this fine spray of toxic chemicals right in the face of your baby. >> that's not right. >> that isn't right. >> reporter: at issue a 19 6 law giving the epa authority to regulate chemicals is in need of an update. the epa administrator says because of legal and procedural hurdles of the 80,000 chemicals in its inventory, the agency has tested just 200 chemicals and only banned five because of toxic heal risks. senator frank lautenberg authored legislation to require manufacturers to provide information on health hazards for all chemicals and require chemical companies just like pharmaceuticals to demonstrate product safety before putting products on the market. >> a will require chemical makers to prove their products are safe before they end up in our children's bodies. >> reporter: the chemical industry strongly disputes the epa numbers, but insists chemical companies agree, safety laws need to be updated. it's just the democrats' approach would hurt businesses. >> it will not do the two things that we really need to do, the two goals are to protect health in the environment and also to ensure that american manufacturers can compete in a global marketplace. >> reporter: moms like christine nystadt who flew in to idaho to talk to her senator says she wants information to make smart choices about what she buys. >> you can't read a label on this pillow and know anything other than it's supposed to confer with, you know, rules for fire retardants. that makes you feel like you're doing something safe. it turns out the exact opposite may be happening. so until the labels mean something, we are powerless. >> reporter: now there are 18 democratic senate co-sponsors, those are democrats, no republicans so far, john, and the spokesman for the top republican on the environment committee, james inhoff tells me he does think this issue is important. he wants to work with democrats, but the way this particular piece of legislation was written it would hurt, he says, businesses and business development. >> so help me a bit further on that one, dana, senator inhoff is open to the goals and most republicans don't love the epa so is there a middle ground here? >> reporter: that is definitely another part of it. there's no question, the legislation gives a lot more power to the epa to regulate businesses, which is a political non-starter for a lot of republicans. is there a middle ground? the truth is that there have been private discussions with consumer groups, with industry groups, and with senators and members of congress in both parties for some time. they seem to be at odds right now, but with the kind of effort that we saw from moms today, going from door to door, that's the kind of grassroots effort that actually does tend to matter in the long-term. so could be. >> we'll stay tuned on that. dana bash, thank you. ahead there's a new sign the economy may be picking up, especially good news for homeowners hoping to sell. we'll have the details in a little bit. but next the man who succeeded mitt romney as governor and still deals with romney's old business. you're the governor of a state that bain capital calls its global home. it's right up the street global headquarters. >> indeed. >> are they a bad company?

>> no, they're not a bad company and nobody is saying they are, including the president. it's a remarkable thing. you know, if you take a little step back to watch how good the republicans are at changing the subject. this is not about bain. it's not about private equity in general. it's about a guy who is holding himself out to be a job creator, whose record is fair game at doing that. i can tell you, that when he was, when he was governor before me, we were 47th in the nation in job creation. we're in the top ten today. the numbers of reforms that he talked about, that we actually accomplished, is considerable. he did one profoundly important thing, and that is to lead the reform of the health care system and that's something he wants to talk about on the national trail. >> i'll come back to his time as governor, but member of the house democratic leadership jim clyburn said bain capital rapes companies. he can't support a company that rapes companies. >> the question is whether mitt romney has what it takes, has the preparation and experience and the empathy to serve as president of the united states. it's not about whether bain is good or bad. i have friends at bain. i have people who support it, who supported the other candidate in my own campaign, so i respect what bain does, and its role in the free market system, but we need somebody who understands that there are multiple bottom lines and that's what we have in president obama. >> you are a friend of the president of the united states. >> and enthusiastic support. >> and serve in the office once held by governor romney. odd place to be? >> sometimes. there are a number of people who have been encouraging me to get out there and you know, hammer away at my predecessor. he's always been a gentleman to me and i don't like that kind of politics, but i do think that his record in his one episode in public life is fair game, and it's a record that does not support what he's holding himself out to be. what i think we need instead and what we have tried to do here in massachusetts and i know what the president's trying to do at the national level is to encourage people to turn to each other instead of on each other and come together to solve big problems. >> i assume you have no doubt who carries the election in massachusetts? >> president obama. >> massachusetts is usually an afterthought. people say it's blue, it's democratic, as solid as can be. >> we don't like to think of ourselves that way. >> most people think president obama will carry the state even though governor romney calls it home but you also have the brown/warren race, one of the best senate races in the country. >> really interesting race, too. >> you have the prospect of aiken digoing back to congress in the barney frank district as he retires and we have that lapse now, no kennedys in the congress. interesting state. not normally the case. >> it is and i think we are thought of as being more reliably blue than we are. there are more unregistered independents in massachusetts than there are registered democrats and republicans combined and we've had 16 years before me of republican governors. we've, we have scott brown now in the senate, and in a tight race with the probable democratic nominee, elizabeth warren. >> let's go back then and make clear what is and isn't fair game when it comes to bain capital, where we started. what's fair and what's not fair game? some people attack the company broadly. people say these guys are rapers, they're horrible. >> i get some people think the whole idea of private equity is bad and doesn't contribute. i'm just saying i'm not one of those people but i do think that it is fair to ask whether a person who represents himself as having a record of creating jobs has actually done so. and we've seen a number of examples made public recently of that not actually happening. that doesn't mean that there's something wrong with that dimension of private equity in some absolute sense, but it does mean that what is being represented as a capability of the republican nominee is undermined by the facts. >> i worked in this state many years ago and my first presidential campaign was covering governor dukakis, someone else who once held your job, ted kennedy, michael dukakis. >> where are you going with this?
