meanwhile, the death toll climbs above 200 after one of baghdad's worst bombings. >> a truck packed with explosives was driven into a building. dozens of children were among the dead. whole families died together. >> and in politics, the waiting game as speculation swirls over who donald trump might pick for his number two. >> i love my job and i love my country. but i'm not going to get into hypotheticals. >> so none of you should bet in all of this. >> newt going to do it? >> as hillary clinton gets ready to hit the road with two of her biggest backers, she remains on defense over those e-mails. >> let me just repeat what i have repeated for many months now. i never received nor sent any material that was marked "classified." >> good monday morning to you. i'm craig melvin from msnbc

headquarters here in new york. let's start with politics on this independence day. nbc's kelly o'donnell and kasie hunt both here with the latest on the two major parties' presumptive candidates. kasie, let me start with you. donald trump once again in hot water for his twitter feed. on saturday this tweet widely criticized as being anti semitic, shows an image of hillary clinton and what appears to be a jewish star over hundred-dollar bills. describe how the campaign has reacted. >> well, craig that image going up on saturday over the weekend. immediately the subject of criticism from some who saw it as anti semitic. at that point, someone posted to the twitter feed a modified version of that image. i'm not sure if we have it, but it shows a circle on top of that star. so clearly, something potentially amiss. but then quite a bit of time

went by after that. and we had silence about this from the trump campaign. in the interim, the anti defamation league put out a statement calling on trump to condemn racists and anti-semites in as strong terms as possible as trump has condemned some of his critics, and other candidates he's run against this cycle. we do have just in a new response from the trump campaign on this. donald trump tweeting this morning, dishonest media is trying their absolute best to depict a star in a tweet as the star of david, rather than a sheriff star or plain star. this echoing some corey lewandowski, as well in an interview with cnn yesterday, craig. >> let's talk about the republican convention starting in about two weeks from today, i believe. that's when trump has previously

said he'll announce. what are your sources telling you at this point. do we know which candidate qualities might matter more to mr. trump? >> well, donald trump has said that he would like someone with some government experience who could help fill in a gap in his resume. he thinks he brings leadership from the business world. but would like someone who could navigate washington for him and government to help him on that. so that's some of what he has laid out there. it's also expected he will try to use his pick to reassure different parts of the republican party that have so far not lined up behind him. and that's one of the real opportunities for donald trump with his vp selection. to try to quiet some of the corners of the party that have been very dissatisfied with him. and also on the eve of delegates going into cleveland, having the opportunity to vote, trying to send a signal that might quiet some of the discussion about delegates who would then kind of do their own thing. not voting for trump as they may have been required to by the

votes in state after state. so in terms of where things stand, the 18th is when the convention begins. we have been getting some indications that the campaign wants the flexibility to be able to announce a pick earlier than that. and at the same time, my reporting talking to various sources indicates there are levels of this process not yet completed. there are requirements given to those who would consent to being vetted, to provide documentation, answer a ver len, interview parts of this, as well. not only with trump, but with others who are doing the vetting. those steps take some time. and so our indications are that process is not yet complete. so we don't think we're on the eve of an announcement. there is still a little bit of time. but expect that it could come before the convention starts. craig? >> all right, kelly o. let's pivot to kasie hunt and talk about the clinton campaign. we know she had that three-hour interview with asians investigating her use of a

private e-mail server saturday. what do we know about that meeting? what happens next in terms of the investigation? >> well, craig, that meeting, of course, taking place saturday morning over the course of three-and-a-half hours at fbi headquarters. of when you think about how long things can lass in a case like this, three-and-a-half hours not actually necessarily that long. she spent more time sitting in front of the benghazi committee in public, for example. but her campaign really trying to turn the page. hillary clinton herself attending a performance of hamilton on broadway on saturday night. the same day that she had given that testimony. the question, of course, how will this ultimately be resolved, and whether or not it will -- will it be resolved before the democratic convention? before hillary clinton accepts her party's nomination for president. and there had been some acceptance in the hillary clinton campaign that this was going to continue to drag on, that this cloud was going to be

over her head for quite some time there. is now some optimism the fact that this interview tack place may mean they're nearing the end of this process. the anticipation was that hillary clinton would be one of the final people interviewed in connection with this investigation. so still an open question as to whether that's the case, whether this is going to wrap-up quickly. and, of course, whether she will be cleared of all wrongdoing, and that no charges will be filed. under normal circumstances, the justice department wouldn't necessarily make public that they had decided not to file charges in an investigation like this. but considering the unusual nature of the case, we could expect to see something public from department of justice. we're just not sure when at this point, craig. >> kasie hunt, kelly o'donnell, a big thanks to both of you. howard dean, former governor of vermont, msnbc contributor. susan del percent o, a republican strategist. governor, let me start with you.

we've got this campaign event tomorrow, in north carolina. hillary clinton and president barack obama appearing together in charlotte. the significance of this event. >> president obama won north carolina twice. it was really one of the most extraordinary wins. we haven't won north carolina for years -- excuse me, once. i guess he lost by a very small percentage in 2012. but it is up for grabs, because of local politics. the governor there very unpopular. the legislature very far out of step where most people in north carolina are. so i do think we have a good shot. and president obama was the one that was led the way on that one. so it's not a surprise he would go there and i think it will help. >> let's talk about this tweet, susan. and we just saw the response from the trump campaign. this is what the "washington post" wrote about trump's continued use of symbolism.

for at least the fifth time, trump's twitter account shared a meme from the racist right and offered no explanation why on white supremacist forums, trump cheered for apparently declaring his solidarity through not so subtle code. seems to be a lot of times to share racist tweets. what's happening inside the campaign? how does this keep happening? >> well, bad staffing, i think, was the last tweet. i think that's what it came down to. but it also comes down to now we're seeing bad management in a campaign. that is just not gelling. and that's why donald trump went out and said, i have a lean machine and that's how we won the primaries. there is something about staffing up and something to be said for having professionals. if you're running for president and doing that saying i'm a great manager and i know who to hire, this is not making your point. donald trump's statement just now that you read earlier, he shouldn't have doubled down. he should have had a staffer say

yesterday or even saturday that this was a mistake, we apologize if we offended anyone and let it go. and it wouldn't go into donald trump's narrative to apologize. just let it be a staff member and let it go. and that's the bigger problem facing the campaign. not this tweet. but what it shows in the lack of management. >> governor, do you buy that? i mean, are we talking about a tweet here, or are we talking about continued dog whistles? >> i think we're talking about both. i am reasonably sure that donald trump himself is not anti-semite. it's hard to do that and be a successful -- well, i'm not sure how successful he is, but be a businessman in new york. it was definitely anti semittic because it came from a right wing racist organization. i do think donald trump is dog whistling hispanics, african-americans, even asian-americans. and certainly he didn't mind taking advantage of the disabled community. so i mean, he is a dog whistler.

no question he's a racist. and anti semite, maybe not. >> well, but if you're racist, aren't you also by definition anti-semite? >> his daughter is jewish. she meerd a jewish man, which makes it all the more egregious. this is before the tweet controversy, the latest tweet controversy. here it is. >> everything the clinton campaign is doing to suppress trump will in the short run suppress trump. because he's not trying. trump's job is, frankly, to quit screwing up, get the election down to three or four big issues, all which come down to a single concept. enough. >> does he sound like a vice president to you? >> well, it sounds like really good advice to me. does not sound like a vice presidential candidate. as a matter of fact, i'm willing to bet all the folks we have been hearing who are in the top

four or five potential picks, this is one giant head fake. i think donald trump is going to look at this as a casting call. and who -- how will it look best and seem best for the public to take in. i don't think we're going to see any of those top five mentioned. >> can trump afford to pick somebody that we're not talking about? i mean, can he really afford to roll the dice and pick somebody that's not even on our radar right now? >> given everything that's happened this campaign, we asked that question every week of donald trump when it comes down to something or another. yes, he can. because he wants -- for him to be successful, he has to be able it to do it where he's comfortable and he wants to do it his way. he's not going to be pushed into anything by anybody. and that's -- that's donald trump. >> governor, i want to play something that chuck todd talked to hillary clinton about. this is on friday. this is what she said about that meeting between attorney general loretta lynch and her husband, the former president. >> hindsight is 20/20.

both the attorney general and my husband said they wouldn't do it again, even though it was from all accounts that i have heard and seen an exchange of pleasantries. but obviously, no one wants to see any untoward, you know, conclusions drawn. and they said, you know, they would not do it again. >> that was on saturday, by the way, we should note. this is, governor, a political gift, to donald trump. has the investigation at this point are -- has this e-mail investigation been -- no matter the outcome? >> here's the deal with benghazi and white water and suicide and e-mails and this other stuff. this has pushed very hard and pretty successfully by the right wing. they have legal organizations like judicial watch raising money to pursue in the courts and get it in the headlines every day. i think, you know, this is part of the narrative. this is what they're going to do. the clintons have never been

fond to have been involved in any of these scandals. and i think at the end of the day, she is going to be elected president, because people want a president they know something about, who they think can do the job. and it's pretty obvious donald trump can't. >> but there is nothing right wing about the state department's own inspector general putting out a report saying this should not have happened if she would have asked for permission to do it, she would have been denied. this is far a right wing conspiracy. she is being investigated by john kerry, a democrat, doj, democratic administration. so that being said, yes, will the republicans use it because it shows -- goes to her credibility and her ability to run an organization? yes. as well they should. >> susan del percio. >> but previous secretaries of state have used private e-mail. >> that's not what they criticized previous secretaries of state for. in the report, governor, they specifically go to her using a home server, which none of the other secretaries of state had used. >> ten seconds, governor. >> that's true. because they didn't have the

opportunity to do that. >> but it's true, you agree. >> but the fact of the matter is, this is yet another bunch of hooey dreamed up by people who don't have enough to talk about or are unwilling to talk about issues of the campaign. the real issues of the campaign, the economy, jobs, education, those are big losers for donald trump. and that's why the right wing can only attack hillary personally, because they can't attack her credibility as a president. >> coming exactly from someone who doesn't want to talk about the e-mail scandal. >> we have to leave it there. republican strategist, susan del perc percio, howard dean, always appreciate when you work the word hooey into comments here. a second gator, there were two alligators involved. but first, panic in the park. a man in the hospital this morning after an explosion in one of new york city's most popular tourist spots. the latest and what's being done to protect people celebrating the fourth. ss be ready when growth presents itself?

moments in panic this holiday weekend when fears of a terror attack already high. first, the sound of an explosion, then the panic. a young man was seen being carried out on a stretcher, not a terror attack, police say. but a fireworks mishap. rehema ellis in central park. first of all, what do we know about the victims' condition and what happened? >> reporter: well, what we know is, craig, that young man now is listed in stable condition in the hospital. he's got a long road of recovery ahead of him. you'll hear more about exactly what happened to him in a moment. but all of this is coming after -- in the city where you point out, thousands of people

were celebrating a beautiful sunday morning. and then a frightening incident. in the city on heightened alert for the holiday. chaos and confusion in new york central park. friends up in arms after another friend was badly injured. police say it was small explosion off the beaten path. 19-year-old connor golden from virginia jumping down from a rock, stepping on what police believe was a home made fire work. his left foot severed, his friend in apparent shock. >> our friend getting the ambulance. >> reporter: police say the three friends are not responsible for the firework, but it's not clear when it got from and when. >> there is nothing to indicate this was placed in the area with specific intent to harm any

individual. >> reporter: his grandparents say this is surreal. >> this is a life-changing thing for this poor young man. >> reporter: bomb-sniffing dogs searching for evidence, an unsettling sight to new yorkers and tourists alike. >> this is very sad circumstance. >> reporter: nationwide, cities stepping up security for the 4th of july holiday. in boston, police are monitoring dozens of surveillance cameras, looking for any suspicious activity. in miami, the coast guard keeping a close eye on the waters, making sure boaters are safe at sea. and in los angeles, a noticeable increase in police officers and dogs at l.a.x. behind the scenes, tactical units aimed at preventing any potential attack. the goal nationwide, a safe independence day with no unexpected fireworks. they want to make certain that

doesn't happen, craig. just a little more on this young man injured. his grandfather says his grandson's leg had to be amputated below the knee. so very serious. and today it's a beautiful day, millions of people planning to come out tonight to watch the fireworks. and you can be sure that there will be thousands of officers who will be out here tonight, trying to make certain it all happens safely. craig? >> rehema ellis in central park this morning. thank you. the university of wisconsin has just released a statement, saying they are deeply concerned about a college student who vanished just hours after he landed in italy for a program abroad. 19-year-old bo sullivan seen enjoying his first night in hom at a coffee bar with friends late thursday night when he didn't show up to an orientation friday morning, his roommate called authorities. solomon's parents then discovered that thousands of dollars had been charged to their son's credit card. wisconsin's dean of students is asking all badgers to keep him in their thoughts.

some chilling new details this morning about the deadly gator attack. the father of lane graves told authorities that not one but two gators appeared during the attack. public records show that as the father tried to save his son and a second gator bit him. emergency responders said matt graves required stitches during the 16-hour search for the boy. at least five alligators found and killed. checking the boxes. the presidential picks get thickened in the election process for their number twos. how soon can we expect a big reveal? keep it here on msnbc. it takes a lot of work... to run this business. but i really love it. i'm on the move all day long... and sometimes, i just don't eat the way i should. so i drink boost® to get the nutrition that i'm missing.

. donald trump taking advantage of the holiday weekend to make some in-roads on his vice presidential pick. trump met with one, indiana

governor pence on saturday. now pence is in indiana at a july 4th parade, in the town of lenton, southeast of indianapolis. after his saturday meeting with trump, pence said that, quote, nothing was offered, and nothing was accepted. meanwhile, hillary clinton is thinking on who could be her running mate remains a mystery. and there's just three weeks to go now until the democratic convention in philadelphia. i'm joined now by "time" washington jane newton small. a bit of developing news in the past few moments. donald trump tweeting about that meeting with governor pence. here's that tweet. spent time with indiana governor mike pence and family yesterday. very impressed, great people. and then, right after that tweet, this tweet. i look forward to meeting joannie ernst today in new jersey. she has done a great job as senator of iowa. and we know senator ernst,

freshman senator, tea party favorite. at this point, do you get the sense that she's on the short list, or do you get the sense that governor mike pence is the front runner, or do you get the sense that we don't know what we're talking about, and is donald trump is going to surprise everybody again? >> well, that would certainly be the default position for anything having to do with donald trump. every time we have tried to guess, anyone in the media has tried to guess what he may or may not do, we have always been wrong. so trying to figure out who trump might pick is very difficult, frankly. and, you know, doesn't surprise me he would meet with joannie ernst. she is a very strong woman. he's had had a lot of problems with female voters and appealing to women voters and so that might help him, although certainly historically, picking a female running mate hasn't helped john mccain or back when carly fiorina ran for the democrats in 1984. it didn't actually help. but certainly, just having a

woman stand by your side, out there stumping for you, couldn't hurt donald trump. and she is a very conservative woman who has great tea party credentials in iowa, which is a swing state. so i could see the appeal for her. >> i think you said fiorina in '84 and i think you mean ferraro. >> oh, i'm sorry. geraldine ferraro. >> that's all right. i was trying to save you from the twitter folks. in terms of advantages, do we think that he's just basically looking for someone who can add something demographically, someone who can add something geographically, someone who is going to be a yes man or yes woman, or is he looking for someone, as he has indicated, someone who can help him on the hill? >> well, he has said he wants somebody with a lot of governance experience, somebody who has potentially been in the senate, been in the senate for years, who can help him get bills through congress.

or can really -- because he himself is, you know, never been a politician before, never run for office before. and so this is a new world for him, particularly the world of governance. and so that is something he wants in a vice president, much in the way that joe biden helped freshman senator barack obama november ganavigate the senate. so certainly joannie ernst can help towards that. other names floated, tom codden from arkansas or corker from tennessee. and those are potential picks. fallon, another one of the potential picks, said she is interested in the job. mike pence, before he was governor of indiana, was a very prominent member of the house and so he knows his former colleagues very well. so all of these people do have a fair amount of experience. by all accounts, i've heard that he had thought of -- he really likes newt gingrich, former speaker of the house, but his staff is leery, because he's not that easy to control.

no one has been able to leash newt gingrich, much in the way no one has been able to leash donald trump. >> excellent point. jane newton small, we did not get to hillary clinton's picks but we'll be talking about this add newseum for three weeks so i'm sure we'll have you back. >> thanks so much. hillary clinton taking her strongest surrogate to the ballots ground state of north carolina tomorrow. we'll have a preview of that, and no fly, no buy? democrats vowing to fight the latest nra bat gun bill set for a vote this week in the house. you're watching msnbc. at the beginning of the 21st century, the earth needed to find a new way to keep up with the data from over 30 billion connected devices. just 30 billion? a bold group of researchers and computer scientists in silicon valley, had a breakthrough they called... the machine. it changed computing forever. and it's been part of every new technology for the last 250 years. everything? everything! this year, hewlett packard enterprise

the house floor, demanding a vote on new gun legislation. paul ryan promised to vote this week on several terror-related measures, including one to prevent terrorists from buying guns. loretta sanchez, thanks for being with me on a holiday. >> thank you. >> the last sit-in, the republicans called a house session into recess. is there going to be another sit-in when you get back to work tomorrow? >> i don't believe there will be. obviously, the democrats are discussing what are their next steps in trying to bring some reasonable gun control measures to a vote on the house floor. one of the things it did was to highlight the fact that a majority of americans, whether you're republican, democrat, or any other party, or not in a party, when americans are looking at all of this gun violence, that there is a need to tighten up some of the

regulations. >> as we're having this conversation, we know that at this point, and, again, it's 10:on a monday morning, so far, in chicago, two men killed, more than 30 others have been hurt as a result of gun violence. talk about the legislation republicans are bringing to the floor, and as a member of the house homeland security committee, why, in your view, is that bill not enough? >> well, no fly, no buy. in other words, if you're on the terrorist watch list, the no-fly list, if you will, for airports, then you would have -- and you wanted to go and buy a gun, the government would have 72 hours in which to disclose one way or the other, whether you could get that weapon. and it's all based on what the words in the language -- the language in the bill are actually about probable cause. well, probable cause is a pretty high level. it's not we suspect you, it's

not we have been watching you. et cete it's not we're checking out what you're doing with other people who might be on the list, it's probable cause. there are a couple issues. the first is, if we have high probable cause that you're a terrorist, we probably have got you already. we've arrested you, so there is no reason why you're on the outside trying to buy a gun. and secondly, the reason we have left you out there is because we're actually following you and we're trying to figure out the whole network of what you're trying to do. just as republican susan collins said, this is a problem when the senate said no to that piece of legislation. and, you know, honestly, i've served with spiker ryan for a long time now, and i don't understand why he would bring up a bill that has already not passed in the senate. so, you know, i really want to get to the table with republicans and democrats and find something that really works for americans. >> if you don't like the probable cause language, what

would be more acceptable language? >> there is the probable cause problem. and then there's the second problem, actually getting it done. so think about this. if you look at the judiciary system and the prosecutorial system, one of the things you're going to see is, we have been limiting the funds. in fact, we have a crisis here in california with respect to the moneys that are actually going into the judicial area. people aren't getting trials, they're waiting five years, depending what type of trial it is. there is not a fast due process, if you will. and so what we're talking about in this legislation is 72 hours. 72 hours for the departmedepart justice to get the fact that you're trying to buy a weapon, to get before a judge. you know, plus you have to tell the supposed terrorist that we're not going to let him buy a gun in order for him to have

counsel to come in and to try to say why are you denying me in front of a court. 72 hours, that's not very long to do that whole thing. there aren't the resources, there just aren't the resources in the system. and especially in the judicial system. so i think this is just a lot of bad pieces to this. i think we need to sit down and really need to think about, are we going to augumenaugment, giv additional fund, a department that just does that because every time somebody, you know, goes to buy a gun and they're on the list, how many times are we going to have to go into court on that? also, remember, the fly list -- i've been on that no-fly list. you know -- which i shouldn't have been. deceased senator kennedy was on that fly list. so these fly lists -- are not very good sometimes. and it's very difficult, even if you are an innocent person, and

you're on that fly list, to get yourself off. of i know, because there have been plenty of my -- the people i represent who have been on that list, and i haven't been able to get them off. >> congresswoman loretta sanchez of california. we have to leave it there. thank you. >> thank you, craig name mourning the victims. iraq starting to bury some of the more than 200 killed in sunday's bombing. that attack not the only one worrying american security officials. ana and your doctor to maintain your health. because in 5 days, 10 hours and 2 minutes you are going to be 67. and on that day you will walk into a room where 15 people will be waiting... 12 behind the sofa, 2 behind the table and 1 and a half behind a curtain. family: surprise! but only one of them will make a life long dream come true. great things are ahead of you when your health is ready for them. at humana, we can help you with a personalized plan for your health for years to come. afdave stops working,

saudi arabia and state television reporting a suicide bomber was killed. two other people wounded. and a blast near the u.s. consulate in the city of jedda earlier today. meanwhile, in neighboring kuwait, a number of people arrested for allegedly planning an isis-inspired attack there. these all come after a bloody week in three predominantly muslim countries. turk turkey, bangladesh and iraq.

an attack targeted families, breaking their ramadan fast. chief global correspondent bill neely joins me from london with the latest on all of these attacks. bill? >> reporter: yes. it does look like in one way those attacks are connected, because isis called on its followers to attack foreigners and indeed anyone it sees as an enemy during the holy month of ramadan, just coming to an end. so the groups in iraq and turkey and bangladesh aren't talking to any kind of central command in somewhere like raqqah in syria. they are responding to the isis call. and the month ends with eid, a day of celebration, later this week. and it's fair to say that authorities across the mid east and muslim world will be braced for isis attacks. just to bring you up to date, the latest incident near the u.s. consulate in saudi arabia, second city jedda. a suicide bomber parked his car

opposite that consulate, he was then challenged by two security men, and he detonated his bomb. they were injured, but no one in the consulate was actually hurt. and it does look like that consulate was the target. it's being targeted before. this time the bomber got to within 30 feet of the walls. it's the first bombing there in years. aimed at americans. iraq, of course, all too familiar with suicide attacks, and isis has claimed its worst bombing in many years. one security official telling nbc news the death toll may have risen to at least 200 with more than 200 injured. craig? >> bill neely in london. thank you. despite the recent wave of terror attacks around the world, here in the united states, officials claim there is no credible threats against this country. but security does remain tight across the united states. this july 4th, with airports being a top priority. msnbc's tony dokoupil got a glimpse behind the scenes how tsa actually screens our

luggage. >> she's pulled the image up, looked at it and knows there is no obvious threat. if we saw something that was an obvious threat we thought was an explosive device, at that point we would shut this area down, evacuate it, call for bomb techs. if they couldn't resolve it, then shut it down, call for explosive ordinance team to come in, the bomb squad, basically. >> here to talk more about it, how authorities are protecting travelers this holiday, cribsen king, national security analyst. let's start with measures the tsa is enacting to prevent attacks, like what we saw in istanbul. what are they doing? >> some of the things that tsa is considering include outreaching -- or outstretching the prescreening that occurs. normally right before the security area, past the initial screening areas.

they're also increasing the number of k-9 units and looking at further detection devices being placed throughout the baggage screening areas. they are doing a number of things and quite frankly, tsa, given their history, has been doing a remarkable job at providing security at airports across the united states. >> what should travelers be on the lookout for? >> i think one of the things that travelers should always be mindful of, regardless whether or not it's the 4th of july or not, is suspicious activity. and then really that -- anything that could be out of the ordinary. you know, someone leaving a bag unattended. people who aren't necessarily dressed for the departure location. we saw in istanbul, the individuals who were approaching the terminal area were are remarked by witnesses as being dressed in winter style clothes in an extremely warm weather

environment. of those are things you want to be on the lookout for. >> talking about airports and security. typically, fairly high at airports across this country. what can be done to protect these so-called soft targets? >> there are a number of things we can do to secure soft targets. and i don't always like to point out to people, what we saw with al qaeda, a really emphasis on spectacular attacks. that would be, you know, atagging a structure of significant symbolism. for isis, though, the crux of the attacks has been behind much more soft targets. individuals. and in that -- the focus has been on crowds. and places with limited egress points so they'll hit a nightclub with the idea of funneling the crowd as far back into the club as possible to further the extent of their damage. so one of the things that we'll have to do in security is begin to look at -- not that this is a matter of if, but when. and how we mitigate that.

we can do that through a variety of things, whether or not we're checking for firearms before the entrances of some mass gathering locations or other explosive devices. by considering the deployment of armed guards if needed. these sort of things are things we're going oh to have to have conversations about. i know, for instance, chicago is having a debate currently whether or not they want to arm their airport security people. >> skrichb, thank you. out of this world. it's an enter planetary 4th of july. what we're going to see here on earth and beyond. this is msnbc. [ guitar playing ] ugh. heartburn. sorry ma'am. no burning here. try new alka-seltzer heartburn relief gummies. they work fast and don't taste chalky. mmmm. incredible. looks tasty. you don't have heartburn. new alka-seltzer heartburn relief gummies. enjoy the relief.

fireworks celebration for tonight for the 4th of july. in washington, d.c., celebrations on the west lawn of the capitol, you may have to deal with some storms, rain could move into the area. clear for chicago, but hot and humid for dallas. and the heat building, craig, not just for today, but also for tomorrow and into the rest of the week. dangerous heat across the south. >> bonnie snyder, thank you. a big day for nasa and space fans around the country. a $1.1 billion nasa spacecraft is scheduled to enter orbit around jupiter after speeding toward the planet for nearly five years now. the probe will study jupiter for the next year-and-a-half, hoping to unlock secrets about how the planet was formed. i'm joined now from philadelphia by derek pits, of course, the chief astronomer at the franklin institute. what amazing discoveries, nasa hoping to get today? >> yes, good morning, craig. nasa is really hoping that this

spacecraft will be able to answer a lot of basic questions, not only about jupiter itself, but also about the origins of the solar system. one of the things that nasa scientists are thinking is that the way the solar system was originally formed, first was the sun. and then after that, jupiter was probably the first planet formed from a lot of the material left over from the formation of the sun, so, thus, it holds a lot of secrets about the early history of the solar system. >> we know that there is studying of the famous magnetic field. what's the importance of learning more about that magnetic field? >> well, actually, there are two things about the magnetic field, about the environment, that is going to help nasa understand a lot. that is being able to measure the magnetic field and the flux of the magnetic field and also at the same time able to understand the graph national field of jupiter. what it helps scientists to understand is whether or not jupiter actually has some sort of a solid core at its very

center. as we look at jupiter, most of what we see is atmosphere. so we want to be able to characterize not only the atmosphere, but also figure out whether there is a core at the center of all that mass. >> my understanding is that they also have three of these lego astronauts aboard this spacecraft. what are these things? >> yes. lego actually created three -- if you will, not quite characters, but three travelers on board this spacecraft. they're small models. one is of jupiter, the god jupit jupiter, holding a lightning bolt. the other is his wife, juno, holding a magnifying glass and the reason it's named juno, as a goddess, she could see through clouds, thus the spacecraft looking through clouds. and finally, gallo holding a telescope, a little over 400 years ago that gallo made the

first telescopic observation, revealing the moons we know jupiter above. >> when juno is done studying jupiter, what happens to the spacecraft? >> scientists are a little concerned if they were to allow the spacecraft to just hang around for a while, it might contaminate one of the moons of jupiter known as you're opena. it's thought that europa has a an environment where there is a liquid water ocean. rather than possibly contaminate that moon with any biological hitchhikers from earth, the spacecraft will be plunged into jupiter where it will be completely destroyed, destroying any hitchhikers with it. >> my goodness, it's fascinating. derek pitts, we always learn something when you're on television. chief astronomer, franklin institute. thank you. have a fantastic 4th. check out live footage of juno orbiting jupiter on nasa tv tonight, 10:30 eastern standard time. nasa tv. you can use your guide to find that channel.
