[ chanting ] >> reporter: within hours states across the country filed lawsuits challenging the law. >> this is salve liberty. it's not just about health care. >> reporter: led by florida, 26 states argue the law's central provision is unconstitutional. the so-called individual mandate. it requires almost every american to purchase health insurance by 2014 or pay a penalty. opponents say the constitution's commerce clause does not give

congress the power to force individuals to purchase a commercial product like health insurance they may not need or want. paul clement is arguing on pa behalf of the states before the supreme court. >> these issues are central whether the federal government will regulate anything it wants to. >> reporter: the government defenlds the sweeping reforms arguing medical care is not a choice, that every american will need health care at some point in their lives and also say that tens of millions of uninsured americans are costing everyone else more. $43 billion in uncompensated costs in 2008 alone, according to government figures. >> no one is saying there's a right to freeload off one's neighbor when you decide not to choose health insurance. >> reporter: the stakes only grow larger with the supreme court taking the case just monthing before an election. >> we're getting rid of obama care and returning to freedom. >> reporter: and the election year blockbuster has again turned the spotlight on the

justices themselves. [ chanting ] >> reporter: as with the bush v. gore case in 2000, will the justices be criticized for letting politics creep into the courtroom? >> the health care cases have huge political overtones. obviously i think the justices will probably put them to the side. the legal stakes are so high that i don't think they'll pay attention that much, if at all, to the fact that it's occurring in an election cycle. they've just got to get the case right. >> reporter: what we're talking about four separate issues argued for six hours over three days. that rarely happens and shows just how important this case is, but even after these marathon public sessions we still won't know the final outcome for likely three months. kate bolduan, cnn at the supreme court. all right. there are several possible outcome following the health care argument. the supreme court could throw out all of the law, or keep only parts in place. that includes the possibility of tossing out the individual mandate and keeping the rest of

the law as-is. the court could also decide to hold off on making a ruling altogether. u.s. supreme court is expected to issue its decision by late june. all right. turning to the national fury that is growing over the shooting of an unarmed african-american teen in florida. protester are turning out in cities across the country. this is tampa a short time ago. they are calling for the arrest of a neighborhood watch captain who claims he shot trayvon martin in self-defense. also under fire, florida's stand your ground law. florida's governor rick scott, is now calling for a review of that law. but the florida state representative who co-authored it argues there is nothing wrong with the law. dennis baxley says it should not have applied to this shooting. >> in the case in sanford that this doesn't apply. there's nothing in this statute that provides you the authority to pursue and to confront people on the street. >> we get a different

perspective from dan gelber who voted against the stand your ground law when he was in the florida state senate, and is now calling for its repeal. earlier today i asked him if the trayvon martin death is a kind of case that he had feared would happen. >> prior to 2005, we had a perfectly good self-defense law. or had been treat understand fairly. in 2005, governor bush signed into law a bill that essentially have took out of the law any requirement that a person in broad daylight, outside of their home, as this case suggests, has to de-escalate a situation, or walk away, if he can. >> so what precipitated this law, then? if you said everything seemed to be fine and then this new law came into place. what was impetus for it? >> i think really the nra, who has really won every major battle in florida.

does these fringe issues, where they really don't have anything to do with a real victim, and we asked every proponent of the law, just give us that single person who was unfairly prosecuted, unfairly convicted or acquitted who shouldn't have been, and nobody could point to a single person in the state in that category. >> so is it your view this is a shoot-first law, because i heard those words from urban league's who said this is a shoot-first law and ask questions later? and in this case, he and others are exemplifying not enough questions are being asked? >> well, listen, i don't want to throw red meat into something that's not fair. i don't think people do stupid or malicious things because of this law. but people who do stupid and malicious things have a defense that they should not be entitled to because of this law. i mean, mr. zimmerman is going to have the ability to muddle up the waters in this because of this law, and he shouldn't have. he clearly did something wrong.

he clearly, if that young man's life means anything it means that justice has to be done here, but he's going to be able to have a defense in this case, or at least start one, and apparently the detectives initially believed he had one because of this law. >> so now that former governor jeb bush has weighed in and says that this is not the intent of the law. it didn't appear based on all of the public accounts, eyewitness accounts that george zimmerman was being pursued by trayvon martin, but instead it was the other way around, and that this law may have been misused in this case. do you believe that that is impetus enough for a real movement to try to repeal this law, and if so, what will it take? >> well, i think the stand your ground part of the law has to be repealed. we didn't need that law. it was unnecessary. it was a solution in search of a problem. >> join cnn's don lemon at serve cynthia tonight fserve cynthia

new york, with fewer than 1,000 homeowners invited to participate. but if successful it could be expanded throughout the country. this woman with the consumer rights coalition says for many it's a better alternative to foreclosure. >> for families what it does is it keeps families in the homes and particularly people with children it means you can stay in the school. you don't have to deal immediately with looking for a new place to live. you're still part of the community you've been living in for many, many years for lots of families, and for the banks, it helps them as well. they tonight have a vacant property they're supposed to cut the grass, you know, painted and keep up. >> reporter: but minnesota realtor josh palmer says many won't qualify for the program. still other families may be so sick of everything, they just want to walk awanchts it's can't hurt good to hear they're doing something about this mess, but a lot of people are just ready to be done with their house and move on with their lives.

slamming into charleston. we have now four watch boxes in effect. so on the wider scale, the severe weather threat is extended all the way into west virginia. now northward. these storms are really getting powerful going through the afternoon. that's because the heating of the day tends to make the atmosphere more unstable and likely to get more severe weather. this means we could see large size hail with the system and a threat of candidates may exist possibly late other than. look at the line coming up across florida. jacksonville, your weather, intermittent in terms of rain, but we will see heavy downpours along i-10, into your region for the remay finder of the day today. severe storms working in advance of the cold front. seeing slightly cooler air. not much difference. incredibly warm temperature ace cross the south and midwest and even the northeast. as we kind of look further to the west, pointing out a brand new weather featuring we're monitoring bringing snow to the higher elevations of northern california as well as areas of the pacific northwest. a really cool seize sewn fo far.

president obama's health care reform act a constitutional. first the gateway issue. the court will look at whether making people pay for insurance is actually a tax. the law says it can't be challenged until the tax is paid. so bottom line, the court may not even have the authority to decide the case. and still, the justices will have to rule whether opponents can sue. don't look for quick decisions. a decision could be delayed for years. the high court's decision could affect how every american gets and pays for health care. lizzy o'leary explains in a storybook form. >> reporter: meet jack and jill. they're married with two kids and together make $49,000 a year. about the middle american income. but like 15 million people with similar incomes, they don't have health insurance. not good in you're worried about falling down the hill. under the new law, jack and jill

are winners. they can buy private insurance from what's calmed an exchange starting in two years. the idea is that lots of people buying at the same time would get a better price. and the plans have to meet minimum standards set by the government. jack and jill would also get a subsidy to help them buy their plan. mary only makes $13,000 selling little lambs. she's also a winner. she can get insurance under an expansion of medicaid. 17 million americans like her will be eligible for that. and about 51,000 kids with pre-existing conditions, like hansel and gretel are also winners. they can't be denied coverage and all kids stay on parents insurance until 26. that brings us to the losers. the roughly 19% of american whose have high cost gold-plated health care plans. like prince charming here. starting in 2018, that fancy plan he gets from her job at the

castle would be taxed a at 40%. he will see his payroll taxes go up try 3 million other american whose make more than $200,000 a year. also on the lose end companies like fairy godmother industries that employs more than 50 people making glass slippers. so it has to offer insurance or pay a fine. 94% of similar-size companies already do, so only a small number would pay more ounlder the new law. we end the story way toss-up. insurance companies would both win and lose. they'll have to paper the government more than $8 billion a year, but they get up to $40 million new customers, like jack and jill, who by law must get insurance or pay a penalty. lizzy o'leary, cnn. earlier i spoke with our legal guys to get perspective on what the court will take up this week. here's how they see it. >> the justices have to actually

decide whether they have the authority to decide this case. explain. >> that's exactly right. the first of the three days of argument will be whether or not an 18. >> -- 18th century law bars courts from having a frame like this. the big deal on this and i'm so excited about these arguments, on tuesday, we're going to get -- >> you're a constitutional lawyer. >> that's what i do. yeah. that's the big day that will deal with the big issue, whether or not this laundry list of powers given to the congress by our founders under article 1 section 8, the commerce clause can properly hold this law requiring an individual mandate, individual responsibility, the power to hold the law constitutional and that's where this case is really going to turn. the first question you'll ask, fredricka, very legitimate, but the focus will be on tuesday.

>> okay. and that's when we talk about the individual mandate. richard, you say, if it indeed becomes the case, or the argument is successful, that this tax penalty comes with this individual mandate, then that really could mean the demise of the entire health care provision. yes? >> it could be, fred. and, you know, with a 5-4 republican man jort majority, think it's a shoo-in to get blown away. that's not going to be the case and i would be shocked if the supreme court turns down this health care. you know, with roberts and kennedy being the swing votes here, and if you look at some of the earlier decisions that they've made, and we look recently to the d.c. court of appeals which upheld a sixth circuit case addressing health care, now these supremes look very seriously at the d.c. court of appeals. i believe they're going to uphold this legislation, you

republicans have more substantive tweets. 3.5 times as likely to mention specific legislation. i follow a lot of people on twitter. sometimes you see attacks going back and forth. one of the things i like about this study, hall of the tweets in which someone in congress mentioned someone collaborative and not critical. far fewer were critical. this is something lawmakers are working on, how to use the new media, including twitter to try to reach a lot of people. they're saying in 2011, twitter became a political power house, and they pointed to what happened around the world, and also pointed to president obama's twitter town hall not too long ago, and let me show you these, the lawmakers who want to succeed on twitter, the ones who were mentioned the most, tweeted earlier in the day, later in the week, and were more likely to tweet on weekend. and this study suggests people should tweet while they're on the house floor. while things are going on.

obviously, the people's work comes first, but if you tweet it during it, it can humanize the process, make people feel involved on it. >> it's not going to be good if they're caught on camera and they're supposed to be listening and it's looking down at a pda. >> when we look at the live footage, you can see people. >> it doesn't look good. it doesn't look good, but we understand they're, you know, doing the people's work in some other capacity. there are certain members that appear to be active than others? >> yes, they looked at all of the hundreds of members of congress and said who is most influential. they punched new numbers for me yesterday. let's go to the screens. the five most influential twitterers or tweeters, according to this study, bernie sanders, who is an independent, then john boehner, then keith ellison, the one democrat in the top five, number four,

representative darryl issa out of california, and number five, john mccain who is a republican. so he is another -- >> senator john mccain. a little boo-boo on that one. >> we'll fix that up. the idea here is that all of the people, hundreds of them are trying to use social media now. this is the best study i have seen that has looked at how well are they actually doing reaching people, getting messages out there, getting things, messages amplified and having involvement with viewers online and ultimately, with voter said. they're doing a good job on the gop side. >> very good. it's just beginning. >> just beginning. you can see everything i posted the whole study for you on cnn.com. facebook and twitter. i want you all to see it. is there value in it, how do you see it? >> i'm sure you will be deluged with messages.

checkpoints and multiple cameras. >> since it was a secure building, why wasn't it shut down so he was caught before he left. >> the gunman still at large was identified as an intelligence specialist working for the affcan blees. no notive has been identified. with so much focus on the actions of sergeant robert bales, marchanti's children are confused. >> there was, you know, there's always coverage about horrible things this man did, but what about the great things my father did over there for this country? and representing the army the way he did. to us, our dad was like superman. >> love him so much, so proud of him. i wish i would have told him more. >> hundreds turned out to honor major marchanti, a teacher who loved his family, his country, and the people he believed he was helping. >> my dad loved though people and i don't think they realize the loss they have had, the

afghan people, as well as our people. >> that man walked in there with the gun, he had no idea what he was taking from so many people. and what he was destroying. it was just totally senseless. >> the family has received hundreds of letters and e-mails from around the world. but it's this last e-mail from her husband that peggy clings to. >> my heart is right beside yours. i feel you here. i love my life with you. >> a life that ended too soon with many unresolved questions why. and we continue to follow the growing public outrage over the shooting death of trayvon martin. protesters are rallying across the country demanding justice for the death of the unarmed florida team. the demonstrators are demanding police arrest george zimmerman. he was the neighborhood watch nt
