captions paid for by nbc-universal television good evening. this is the end of the supreme court's term. on thursday we learn their judgment on the obama health care plan, but today came the other major decision of this late term when the court struck down some key portions of that controversial law in arizona meant to crack down on illegal immigration. it's an emotional issue, a local issue, and political of course especially in an election year. the court said today in effect the federal government gets to deal with immigration not the states. we have it covered tonight from washington to arizona. to the law, itself, we begin with our justice correspondent pete williams at the supreme court. pete, good evening.

>> reporter: brian, this is a narrow victory for arizona, but enough of one for the governor to declare victory today and to vow to start putting the surviving parts of the law into effect as soon as the legal battles are over. while the court today struck down major parts of arizona's tough immigration law, one that inspired state crackdowns around the nation, it unanimously upheld the most controversial requirement -- that police making arrests or traffic stops check the immigration status of anyone suspected of being here illegally and detain them until their status is verified. >> this is the day that we have been waiting for and, make no mistake, arizona is ready. we know the eyes of the world will be upon us. >> reporter: four justices joined anthony kennedy's overall majority opinion. the court's three liberals and chief justice john roberts. the three other conservatives dissented -- justice elena kagan, who worked on the issue before she came to the court, sat this one out. today's ruling came with a

warning for arizona that if police detained people too long to check the immigration status or used the law as a pretext for rounding up suspected immigrants then the part of the law upheld today might cross the line of what is constitutional. >> i think the court is saying there are very strict limitations on how this provision can ever implemented. i think it is also saying there are substantial legal matters to be resolved before any implementation goes forward. >> reporter: the surviving part of the law now goes back to the arizona courts to consider whether it invites racial profiling, something the state strongly denies. today's ruling struck down provisions of the arizona law that made it a state crime for illegal immigrants to look for work or to lack proper immigration papers and that would have let police there arrest without a warrant anyone they suspected of being here illegally. justice scalia spent 11 minutes reading a forceful dissent, saying arizona should be entitled to pick up the slack in lax federal enforcement and he called the obama

administration's new policy, letting children who were brought here illegally, remain, quote, the non-enforcement program. the court will be in session just one more day this term, thursday, and that's when we'll get the health care decision ending this term with maximum drama. brian? >> all right. pete williams, where it all happened today. pete, thanks. now to where this all started. this was the arizona case the court decided today, after all. nbc's mike taibbi is there tonight and has reaction for us to the court ruling. >> reporter: it only seemed like a normal day for leticia ramirez's family, her husband off to his construction job, and her children watching early morning tv. but she and her husband have been in this country illegally for over a decade and when she later watched the supreme court ruling unfold, she said the verdict though it only upheld the so-called show your papers part of the law was still threatening. >> the whole community won't be able to go out, have a normal life.

they're going to be afraid that if we go out we might get stopped just for your color. >> reporter: kelly townsend is a mother, too. >> my daughter is half hispanic. >> reporter: she and other supporters of 1070 saw today's ruling which requires law enforcement to check immigration status as a clear win and a reason to keep pushing for the parts of the bill ruled unconstitutional. >> i do believe that is a victory that was the heart of sb-1070. >> reporter: this is where the rubber meets the road. meanwhile on the front line of the state's efforts to curb immigration local units like pima county's border crimes unit work with federal border patrol agents to try and stem the flow along 120 miles of border. >> they get to this spot, they're almost home free. >> yes. >> reporter: the sheriff's department has detained and arrested hundreds while sb-1070 was drifting in the political winds, and the pima county sheriff says the ruling will change nothing about how this

job is done. >> it doesn't take a genius to determine whether somebody is here illegally, given the reality of our work. >> reporter: it's also a reality that most in this state believe arizona must do what they say the federal government has not done. >> this is the law. we need to enforce it. >> reporter: and the reality, too, that one group, primarily, believes today's ruling leaves them as vulnerable as ever. arizona's already spent about $3 million defending its controversial law. most of it from private donations. there are some questions raised today about whether they'll still have the appetite, the political will to continue to defend the law vigorously if the taxpayers have to start footing the bill. >> mike taibbi in phoenix for us tonight. mike, thanks. now we'll talk about politics and the law. first of all, all of this, of course, taking place in a presidential election year. with us now our chief white house correspondent and political director chuck todd, who is at the white house. chuck, look at this for us vis-a-vis the campaign under way.

>> reporter: well, in crass political terms, today was a day where the obama campaign was pretty happy with what happened and the romney campaign was not very happy. let's start with president obama. you talk to some democratic strategists and they say the part of the law that was upheld will only help them motivate hispanics even more and help them essentially alienate them from the republican party. as for mitt romney, brian, you saw today he doesn't like talking about this issue right now because they know the fine line they have to walk between not looking like they're contradicting what romney said during the primary campaign and not alienating hispanics. he said today he was against the decision, if you will. he wished that the supreme court had given states more leeway, but he's trying not to talk about it much. he wants to talk about the economy. >> all right. chuck todd on the white house lawn. thanks. that's politics. now it's always good to ask a lawyer. with us here in our studios in new york our chief legal correspondent savannah guthrie. savannah, what survives here and where to from here? >> actually, the most

controversial provision, the one that allows state officers to determine the immigration status of anyone they've lawfully stopped. i think we'll see more lawsuits, frankly. this is a law that has never gone into effect because of this supreme court litigation. well, now it will. and that issue about whether that provision of the law leads to racial profiling will now potentially be at issue. that was not something the court decided today but now the law will go into effect and you can expect lawsuits from plaintiffs to say, hey, my constitutional rights were violated. >> as everyone has said we'll be back at this thursday when the next big decision comes down on health care. savannah guthrie, thanks. always a pleasure. there were two other supreme court rulings today, including a case originally brought from montana, a state that has largely managed to keep outside money out of its politics, but not anymore. the justices said their controversial ruling in that citizens united case that opened the big money flood gates applies to montana and every other state. also, the court ruled today that

juveniles can't be given mandatory life sentences without parole. they say that's cruel and unusual punishment and, therefore, unconstitutional. also in the news we are covering tonight a tropical storm in the gulf of mexico pummelling the florida coast line, not notable for its power as much as its size and its slow, meandering track. tropical storm debby has dumped 10 inches of rain in the panhandle in just over 24 hours. 20 counties have been declared disaster areas, and the governor has called up the national guard to help. our report from nbc's kerry sanders. >> reporter: tropical storm debby is now soaking parts of the florida panhandle with up to 5 inches of rain an hour. the u.s. coast guard rescued a family of nine and two dogs stranded in a vacation house on a small island near apalachicola. >> you're all right. >> reporter: and there have been at least three reported tornadoes. in venus, florida a 32-year-old

mother died but saved her 3-year-old daughter as she cradled the girl in her protective arms. >> this is about 400 yards of nonexistent road. >> reporter: in pasco county some flooded roads are closed. homeowners are sand bagging as fast as they can. as those waters recede in other areas, sinkholes have started to open. >> thank god it didn't happen while we were here. it's still emotional. >> reporter: in elvers, florida the river swelled its banks. fun for some kids but not for life-long resident barry huff. i'm concerned about snakes and i know you are. what do you need to do now for your property? anything? or is it too late? >> ha ha. too late. >> reporter: tropical storm debby has hammered more than 300 miles of florida. 50-mile-per-hour gusts have knocked out power to more than 35,000 residents and forced the evacuation of 600 inmates from a jail in pensacola. tonight in florida and southern

georgia there are warnings to expect more of the same. kerry sanders, nbc news, brooksville, florida. now to where this is all headed and when. and for that we check in with weather channel meteorologist jim cantore. he's about 200 miles north along the coast in st. marks, florida. hey, jim, good evening. >> reporter: good evening, brian. we're here at the st. marks lighthouse. you can see it behind me. it's amazing. if this thing isn't coming ashore i'd be very surprised right now because we've had very heavy rain. occasionally winds have gusted 50 even close to 70 miles per hour up in apalachicola. but the event here is rainfall. let me show you what has happened as we set the stage here. first of all clear water over 10 inches of rain. yesterday a rainfall daily record in tampa well over 7 inches. they've had over 9 already with this thing. as we take you up into the panhandle these amounts are coming in so quick we've already gotten up to 15 inches of rain just south of the state capital here in tallahassee. so this is where this band is

setting up tonight and this rainfall event as well. you can see how much more rain is going to fall and we're talking about amounts which could exceed 15 inches. at the rate they're coming down, especially at 3 to 5 inches an hour, one of these is coming in right now. we could get that 15 inches in one night so an area that has extreme drought like we have right now, almost the worst category, this literally in 24 to 48 hours is going to go right out of that and possibly into a massive flood. that is a huge concern across the entire state of florida, specifically this evening the panhandle. back to you. >> so while we have covered bigger and much more powerful storms this sure is a rain maker and a formidible one. jim cantore with us from the florida coast tonight. thanks. overseas tonight decidedly mixed emotions in egypt after this weekend's news that mohamed morsi of the muslim brotherhood was officially declared the winner of that country's first democratic presidential election. this means big changes in egypt

and beyond especially in that region. our chief foreign correspondent richard engel joins us again tonight from tahrir square. richard, people are just coming to grips with how momentous an event this really is. >> they certainly are. big changes could be ahead. supporters of the muslim brotherhood, mohamed morsi, are still here in tahrir square tonight celebrating, playing music as you can hear, hoping that this will be the start of a new islamic state in the middle east. what an incredible change of events. when this revolution began a year and a half ago, in this square, mohamed morsi was behind bars. today morsi was touring president mubarak's old office, even sitting down in his old chair testing it out for size. critics say that the rise of the muslim brotherhood to power will be absolutely disastrous for this country, turning egypt certainly anti-israeli and perhaps anti-american as well. brian? >> all of that will deserve

watching over the coming days. richard engel in tahrir square tonight. thanks. still ahead, as we continue along the way on this monday night the mean season. the fires in the american west so bad now half the nation's firefighting aircraft are all working in one state. later, let the games begin. it looks like michael phelps might have met his match. a great rivalry in the pool. on the road to london.

as we mentioned we've got a dangerous situation in the american west. conditions are bad. red flag fire warnings are posted from kansas all the way west to california and in colorado it's downright urgent. 11,000 people evacuated right

now tonight, 12 active fires burning. look at this smoke plume. this was captured by our veteran cameraman ray farmer on approach into denver's airport. it looked more like the aftermath of a nuclear explosion from the air. nbc's miguel almaguer is covering for us tonight in colorado springs. good evening. >> reporter: brian, good evening. the fire burning in the hills behind me has been described as relentless, what some feared as a worst case scenario after a prolonged drought here came true. it's a blaze that, for now, crews cannot stop. fueled by dry brush, fanned by 30-mile-per-hour winds, the waldo canyon fire in colorado springs is a monster that consumed five square miles in just hours. >> i think it's probably the greatest natural threat we have seen in this community in the last 30, 40 years. >> reporter: the blaze, closing in on homes, forced 11,000 to evacuate sunday. hundreds of tourists left vacation campgrounds to seek shelter in a high school gym.

>> we're used to the hurricanes and evacuating. now forest fires and it's just like reminding us of being back home with the hurricanes. >> reporter: tonight popular campgrounds and state parks are shrouded in smoke and closed. across colorado, at least 12 major wildfires are burning tonight. in estes park, a gateway to the rockies, 22 homes were destroyed by a fast-moving blaze. in fort collins, the hyde park fire has now claimed 248 homes. 3,000 are still evacuated. marco mendoni is living in a motel. >> this is my life right now, and right now we're in limbo. >> reporter: what makes it so difficult to fight? >> you have extreme fire behavior, large, flaming fronts. we can't get right up on the edge of the fire. >> reporter: today fema authorized the use of federal funds to fight fires in colorado and the air force brought in four specially equipped heavy air tankers to join the more

than 70 aircraft already in the fight. >> almost half of all the airborne fire suppression equipment in the country is in colorado. >> reporter: the worst fire season in more than a decade is tonight, nowhere near over. brian, you can probably hear and see the big threat tonight -- wind, a red flag warning in some 11 states across the west. as for the blaze here it's charred some 3400 acres. it is 5% contained. the mean start to a fire season that is threatening both lives and homes. brian? >> a terrible situation out there in colorado springs tonight. miguel almaguer covering for us. miguel, thanks. up next here this evening, too close to call. they've looked at it closely. a race so close even a photo finish wasn't enough.

a government panel is tonight urging doctors to conduct regular obesity

screening during check-ups. they say they should regularly calculate the body mass index for every patient they see. for example, a normal bmi is less than 25 and an obesity bmi begins around 30. well, it started out beautifully. eric and megan had a beautiful wedding in michigan and a reception right there on gun lake in shelbyville but during the wedding photos ended up in gun lake because the quaint, wooden dock there on gun lake just couldn't handle that many people. it was a big wedding party. in the era of digital photography a true photo finish is rare these days but there was a real tie in the u.s. track and field olympic qualifying trials in the women's 100 mile meter race. an exceedingly rare dead heat for third place and a spot on the u.s. olympic team. allyson felix and jeneba tarmoh were both credited with times of

11.06:08 seconds after a review of the photo finish. now it's up to them to decide to break the tie either in a runoff or with a flip of a coin if you can believe it. last week we told you about the hurdler lolo jones who has overcome so much hardship and gotten a lot of attention lately and has overcome heart break at the last olympics. well, she has earned her spot on this year's team, finishing third. up next an exciting day in the fight for who will rule the pool at the london olympics.

we are just 31 days from the start of the summer olympic games in london and tonight the action is in a swimming pool in nebraska and the u.s. olympic swimming trials featuring the top two male swimmers in the world. nbc's kevin tibbles is covering the countdown to london and is with us from omaha tonight. kevin, good evening. >> reporter: brian, there are 1800 swimmers competing here this week, but tonight all eyes will be on two of them -- michael phelps and ryan lochte. he's the greatest swimmer of all time -- is he about to meet his match? michael phelps simply dominated in beijing.

eight events, eight gold medals. never been done before. enter the challenger to the crown, ryan lochte. >> it is lochte! >> reporter: no stranger to world records or the olympic podium, and the first real test of phelps' metal. >> when we step on the pool deck that's kind of our field -- our battlefield. you know, we do everything we can to try to get our hand on the wall first. >> reporter: 27-year-old lochte has trained nonstop for the last four years with a steel-eyed focus on london. he's beaten phelps but never at the olympics. >> i get so excited for stepping on the blocks and trying to race him. i feel like this is my time. >> reporter: the first big showdown? tonight. the grueling 400-meter individual medley. in today's preliminaries, a shot across the bow. lochte beat phelps by 4 seconds. >> we don't have a super bowl. we have an olympic games. it happens every four years. >> reporter: formidible titans

drawing from each other, pushing each other. lochte's coach says racing phelps has made ryan a better swimmer. >> any time you have a chance to race him it's going to be a big challenge, so i think that's helped ryan and by the same token ryan isn't afraid to race and i think that's helped michael. >> reporter: they are bringing attention to the sport like never before from magazine covers to video games. and a myriad of commercials and sponsorships. >> i'm ryan lochte and i'm here to finish first. >> reporter: but in the pool there can only be one winner, and lochte says he's ready. i want to go down in history as one of the world's greatest swimmers ever to swim this sport. >> reporter: to achieve that all he has to do is beat the best there's ever been. >> michael hates to lose more than he likes to win. that's a rare athlete. >> reporter: and with london only a month away, tonight's matchup is bound to be the beginning of an epic rivalry that will continue right to the olympic games. brian? >> all right. kevin tibbles in omaha tonight.

by the way, these olympic trials will be televised tonight here on nbc. that's 8:00 eastern and pacific. and for us for now that's our broadcast on a monday night. thank you for being with us. i'm brian williams. of course we hope to see you right back here tomorrow evening. good evening and thanks for joining us. >> summertime is when you find more families hanging out at local parks. but many in the south bay day one of those very popular parks is off-limits to them. especially after a 14-year-old girl was murdered 2 1/2 months ago by gang members. here's the latest on a park known to be gang turf. >> reporter: you'll often find
