rouge, louisiana. the new details just into our newsroom. >> reporter: i'm chris lawrence inside quicken loans arena where we'll bring you up to date information of everything that happens at the republican national convention. the security, the issues and what local delegates from d.c., maryland and d.c. are most concerned about. all that coming your way next. good afternoon on a busy monday in the news. we start this afternoon in the storm team 4 weather center with tom kierein because as we are talking about this heat, we're talking about storms. >> the camera looking in direction of where we've got severe storms. they're going to move in here in a half hour coming into the metro area.

indicating it's a weather alert day. >> we'll have updates as the storms approach. we can see them on storm team 4 radar. areas in yellow and orange, those are the strongest storms and they're now roaring across montgomery county just coming out of loudon into fairfax county and further south, northern prince william county and down toward stafford and spotsylvania as well. they're advancing to the south and east getting closer to the metro area here in about another half hour or so. just about to hit gaithersburg and across the potomac river it looks like to the north and west of ashton and that area and further south across route 50 to northern prince william county. this is coming into fairfax county and montgomery county shortly. these towns will be affected. gaithersburg, rockville, fairfax city, washington itself by 5:00. should be right downtown based on the speed of these storms as they move on through. brief downpours. a lot of lightning with these as well. maybe s

up to around 50 to 60 miles an hour. frequent updates all afternoon. back to you. >> we'll check back with you and lauryn ricketts within the next several minutes to see how the storms are developing. of course you can stay ahead of this with our nbc washington app. jim? >> wild weather day out there. thanks so much. here at the live desk, we're monitoring the latest on what louisiana's governor just called a diabolical attack. yesterday's killing of three law enforcement officers in baton rouge. police just confirmed what nbc news has been reporting that the shooter was 29-year-old gavin long. he served as a marine and now investigators are confident that he was the only active shooter at that scene. they also believe he traveled from his home state of missouri to baton rouge specifically to target police officers. in the wake of the deadly police shooting of alton sterling in that city. >> it's not justice for alton sterling or anything else that happened in this state or

it's not justice for anybody. it certainly is not constructive. it's just pure, unadulterated evil. montrell jackson had served on the police force for a decade. three other officers are still recovering from the shooting at this hour. we'll have another investigation update later on "news4 at 4:00." to the race for the white house, and all eyes are on cleveland, ohio, where delegates for the republican party have gathered to make it official with donald trump. news4's chris lawrence inside the quicken loans arena where the convention is officially under way now. hi, chris. >> reporter: we are down actually on the convention floor to try to give you a real sense of what

one of the most unique political events in recent memory. we're steps away from the main stage where you can see they're showing a lot of tweets and pictures that a lot of delegates have been posting on social media since they got here to cleveland. i can tell you there is lots to talk about here. it was just a couple hours ago where reince priebus, rnc chairman, gavelled this convention into order. take a listen to what we heard. >> this convention will come to order! >> reporter: what we heard right after that was a song, the song "happy together." no coincidence when you remember just how fractured this party was coming into this convention. there's still a movement out there that even this afternoon was trying to deny donald trump the nomination as the republican nominee. there have been protests outside. e

force. we'll dive into all of that including what our local delegates are doing. i want to send things upstairs to my colleague tom sherwood following the virginia delegation all day. tom? >> reporter: hey, chris. you know the polls are showing that donald trump is having trouble with hispanic voters. now, coming up at 4:30, we talked to someone with the virginia delegation from loudon county. a native of puerto rico and says those polls are wrong. chris? >> i had an opportunity to talk to some delegates from virginia. one of them told me that they're not completely together. there's still some dissent out there and some that don't agree with donald trump's platform, the platform of the party in particular. i sensed an overriding need to

beat hillary clinton and delegates are pushing back that to say we need to unite to win the white house in november. we have a lot coming up. ten minutes from now, i'll tell you where the virginia delegation is here on the floor and what state surprisingly enough is getting snubbed. i'll send it back to you. >> all right. thanks, guys. in the opposite corner, hillary clinton called for the end to the "madness." she addressed the naacp's annual convention in cincinnati and condemned the recent deadly shootings of law enforcement officers and proposed criminal justice reforms including new guidelines on use of force and legislation to help end police bias and racial profiling. a judge in baltimore today acquitting the highest ranking police officer charged in freddie gray's death. >> the verdict stated that lieutenant rice committed

crime by not seat belting gray in the van where gray suffered those injuries. >> news4's chris gordon is covering the trial for us once again. >> reporter: lieutenant brian rice was supervising police officer on the scene and today the judge found him not guilty of involuntary manslaughter, reckless endangerment and misconduct. lieutenant rice helped load freddie gray into the back of the police transport wagon and failed to secure gray with a seat belt or order someone else to. in this nonjury trial, judge barry williams ruled that gray sustained his fatal neck injury inside the van but that prosecutors failed to prove how and when gray was hurt. >> the judge did say he did not find beyond a reasonable doubt that lieutenant rice had caused the injury. >> reporter: ahead at 5:00, how this acquittal of lieutenant brian rice is sitting with the

came to court today. that's the latest from baltimore. back to you. relief is coming for some metro riders but for others get ready for more long delays. where metro's next big phase of maintenance will slow things down for days. showers, storms, intense heat. it's getting wild out there, folks. we've got a

fios is not cable. we're wired differently. so we wired the wagner's house with 100 meg internet. which means that in the time it takes mr. wagner to pour a 20 oz. cup of coffee, tommy can download 30 songs, and jan can upload 120 photos. 12 seconds. that's the power of fiber optics. and right now you can get 100 meg internet with equal upload and dowloads speeds, tv and phone for just $69.99 per month online. cable can't offer internet speeds this fast at a price this good. only fios can.

>> we're having storms roll through the area. this is outside the nbc studios. you can see that line. look at those clouds moving right in. the winds have picked up. you're going to see heavy downpours if you haven't seen already all throughout the region. this is right outside nbc 4 studios. that's where we're under a severe thunderstorm warning. just happened until 5:00 p.m. for the entire district and now they expanded it and put it out ahead. severe thunderstorm warning until 5:30 even through charles county and coming down through spotsylvania county. here's the line right here. a lot of lightning. really breezy conditions. winds up to 60 miles an hour. we've had some reports of some

that's been west. so we'll have to watch for that. if you're headed out, watch this line that will sweep through here. >> westbound traffic along i-66 at route 15 still being detoured with cleanup. a tractor-trailer hit a guard rail near that overpass and that caught fire. chopper 4 over that scene in haymarket after it happened. the driver is charged with reckless driving. this is the las metro safetrack phase 4 in northern virginia. no trains are running between pentagon city and reagan national airport. the crystal city station is also closed. crews will then turn their focus on the next work zone. surge 5 begins on wednesday. on orange and silver lines

ballston. again, expect lots of delays. easing congestion along a busy local highway. there's a big new plan in the works. a huge honor for an american hero. why this man just received the

i'm chris lawrence back on the floor of quicken loans arena bringing you live coverage of the republican national convention. i want you to take a look behind me. just a few minutes ago, the delegation from virginia went absolutely ballistic. chairman reince priebus said that the nominating rules had passed. there is a group of delegates here, not just in virginia, but a

felt like they were shut out of the process that donald trump's campaign and rnc colluded to pass these rules and leaving the grassroots out. in that crowd, is virginia's former attorney general. one of the loudest voices raising his hand and shaking his hand and even taking off his delegate badge at one point. we'll turn that video around. you'll see it yourself in a few minutes once we turn it around. sorry about that. again, there is just so much going on here right now. this is virginia. this is where they are stationed in relation to the stage. the thing is, the host state, ohio, usually gets the prime position. whatever state it is. in this case though, ohio is sort of off stage left behind pennsylvania and a lot of that is due to the ongoing feud between governor john kasich who said he's not even going to come to the convention and the donald trump campaign. all th

this fight over how the rules were passed. again, we'll turn that around and stay on top of all of the developments right here on the floor. >> thank you, chris. >> we want to turn to the weather. we are in weather alert mode here at home. you can see the very windy conditions just outside our studios. >> it is getting wicked out there, tom kierein. >> getting dark, too. the sky really looking very dark and ominous coming in from the west and north. that's the leading edge. very heavy rain and lightning that's coming in as well. these storms have a history of producing some damaging winds. they are about to hit the metro area. as we look at storm team 4 radar and live view outside, that's the view from here at nbc 4. you can see the dark clouds about to move in coming in from the west. not much wind here yet, but the winds will quickly pick up as the storms surge on through. look at storm team 4 radar. just about to come right into washington. they're just now crossing the beltway. they end

baltimore down to near fredericksburg. just along the i-95 corridor. leading edge of this is just about to come into washington to braddock, clinton, over toward arno arnold. the other line farther south is tracking off to the east. it will come into southern prince george's county, charles county as well. so here comes quantico, indiana head, waldorf, allenes fresh in far maryland and northern st. mary's county. this is rapidly moving off to the east. as it sweeps through, gusts of wind to around 60 miles an hour. in addition, really heavy downpours. may only last 20 minutes or so but there could be ponding of water. frequent lightning, too. so if you have plans to head out, best idea is stay inside. wait until this passes which is going to be done in another hour or

then things will improve. look at temperatures and how they'll be dropping. right now we're in the 90s in the immediate metro area. dropping down into the 70s within the next hour. it may rebound a bit back into the mid 80s by 7:00 p.m. may get another few thundershowers coming in by late evening back down to the mid 70s. you can see the rain already beginning to start here in upper northwest washington looking into montgomery county. there's that wall of rain you can see in the distance. i don't see lightning with this. storm team 4 radar is showing quite a bit of lightning with these storms as they come on through. live view from our tower camera to the north and west. another tower camera. there's that leading edge of the cloud cover passing over washington. there is the national cathedral. you can see how dark the sky is getting. it looks like nighttime. capitol. dark clouds about to come over the capitol building as well. temperatures are dropping. dulles down to 73 while at

index. for the next several days we'll get a break from the high heat and humidity during the day tomorrow. may get a thundershower noontime. then low humidity. wednesday and thursday looks great. then here comes another heat wave. hottest days may be next saturday and sunday up near 100 degrees. maybe lingering into monday. after that, we'll cool down a bit. storms on saturday and first part of next week. we're back with frequent updates. a weather alert day. >> thank you, tom. zika mystery. first at 4:00, why one of the country's newest countries of this virus has doctors puzzled. thousands of you drive it every single day. why the big plan to speed up your commute along a busy highway is going to need help from you. stay with us.

first at 4:00, it's one of the biggest complaints about living here. we're talking traffic, folks. >> one of the biggest problem spots, i-270. officials are looking at ways to improve the road and are willing to spend big bucks to inspire ideas. >> reporter: it is known as maryland's most congested corridor. i-270. if you drive it, you know what i'm talking about here. the traffic can beta

times. how do you fix it? maryland leaders say they don't exactly know what they should do at this point. today they're announcing that they're offering up $100 million for innovative solutions that can find a way to get around the traffic and the congestion here. sort of an outside the box approach to solving congestion. >> we don't want to put the cart before the horse. we're putting up $100 million to attract the best ideas from transportation innovators and companies from across america to come up with the best ideas. it's not what i want to see. it's what the best ideas are. we'll figure that out when we get proposals. >> reporter: you look at traffic as it continues to move on northbound and southbound 270 in potomac area and what do comp e commuters say they would be willing to do to improve the commute. a medical mystery in utah. health officials are trying to

after being affected by the zika virus passed it to his health care worker. the type of mosquito does not live in the area where they live. this marks the first death of a person infected with the zika virus in the continental u.s. doctors do not know how or whether the virus contributed to the death. the person was elderly and had another underlying health condition. on a mission as the republican convention opens in cleveland, meet the local woman who is trying to do something in cleveland that some might say is going to be a tough job. weather alert. we're keeping an eye on rough weather that has been lighting up storm team 4 radar all afternoon. when the storms could be in your neighborhood first at:00. 4

when you have type 2 diabetes, like me, hi, i'm dominique wilkins. there's a moment of truth. and with victoza®, a better moment of proof. victoza® lowers my a1c and blood sugar better than the leading branded pill, which didn't get me to my goal. victoza® works with your body to lower blood sugar in three ways-- in the stomach, the liver and the pancreas. and while it isn't for weight loss, victoza® may help you lose some weight. non-insulin victoza® comes in a pen and is taken once a day. (announcer) victoza® is not recommended as the first medication to treat diabetes and is not for people with type 1 diabetes or diabetic ketoacidosis. do not take victoza® if you have a personal or family history of medullary thyroid cancer,

or any of its ingredients. stop taking victoza® and call your doctor right away if you get a lump or swelling in your neck or if you develop any allergic symptoms including itching, rash, or difficulty breathing. serious side effects may happen, including pancreatitis. so, stop taking victoza® and call your doctor right away if you have severe pain in your stomach area. tell your doctor your medical history. taking victoza® with a sulfonylurea or insulin may cause low blood sugar. the most common side effects are headache, nausea, diarrhea, and vomiting. side effects can lead to dehydration, which may cause kidney problems. now's the time for a better moment of proof. ask your doctor about victoza®.

now at 4:30, convention in cleveland. the republican national convention officially under way. we'll have team coverage. a storm team 4 weather alert. it turned into a sweltering and stormy afternoon. time for an update from meteorologist lauryn ricketts. how are we looking? >> looking like we're seeing thunderstorms rolling through the area right now. it's gotten dark and windy and those temperatures have dropped if you have seen rain. let's show you what's going on out there. it's a little on the dark side once you step outside. especially if you're in the district and points to the east. severe thunderstorm warnings in orange. severe thunderstorm watch in pink. you can see they continue to trim that severe thunderstorm watch and will continue to trim that as the main line of storms moves out of here. this is the main line coming through the district right now. if we're inside the beltway and think about going for a walk outside, might want to wait a bit. these are traveling east 30 to

if you haven't seen any rain yet, get ready for it. you're not only going to see heavy rain and lightning but you're also going to see some wind. we'll time it out and let you know when you can expect it east of i-95 in just a few minutes. gu guys? >> reporter: i'm chris lawrence back here live on the floor in quicken loans arena for the republican national convention. i can tell you the virginia delegation has now become ground zero. look at this crowd of people crowding around the delegation from virginia. this is the delegation. that's former virginia attorney general ken cuccinelli speaking right now. one of the loudest voices we heard a few minutes ago as chairman of the republican national committee said that the rules had passed. the rules, the nominating process, the rules had passed and this place just erupted. the virginia delegation again with mr.

way. at one point i saw him rip off his delegate badge and toss it in the air. they say that the feelings of grassroots republicans are being ignored and basically the donald trump campaign and rnc got together to pass these rules without a lot of input. they've been demanding a roll call vote. a lot of energy in the room taking place right around virginia as people huddle around to see what happens next. i want to talk now to my colleague, steve handelsman looking at the other big issues happening here in cleveland. steve? >> reporter: first, let me hook back a bit, chris, and talk a little bit about what you were talking about. i just talked to a louisiana delegate, a texas delegate, and they say, yes, this is a disrespecting in their view of the grassroots. this is what it boils down. delegates here who are opposed to donald trump being the nominee, want the ability of trump delegates to change

else. frankly, if that big, big rule were put to a floor vote here, it would lose. the likelihood of delegates being able to vote against trump is less. a floor vote itself would embarrass trump and so that's the fight now to prevent that kind of embarrassing floor vote. as this rnc officially tries to stay on message. >> this convention will come to order. >> reporter: as the republican convention kicked off, today's theme was keep america safe. spotlighting donald trump's promise of law and order. to voters horrified by deaths in dallas, baton rouge, orlando and in europe. >> president trump is the only one who will be tough on terrorists and is going to provide law and order for this country that we badly need. >>thy thi i think people are lo for protection. we're in a world that's scary. we're looking for leadership. >> it's like an

they're finally figuring out who is watching their back and who is not. >> reporter: trump comes to the convention tonight to introduce his wife, melania. big name republicans are not speaking this week or attending because trump is the nominee. no bushes, no mitt romney, no john mccain, ohio governor john kasich won't come to the convention in cleveland angering team trump. >> kasich, who frankly was invited to participate, i can't answer. makes no sense. he's embarrassing his state frankly. >> reporter: to punish ohio, it's a big swing state, delegation got stuck way over here on the side of the floor. 78% of the republicans in the nbc news poll worry their party is not united which the delegates here hope they can fix this week. 38% of republicans say they are no

only 38% of republicans now say they're satisfied with donald trump as their nominee. something that he hopes that melania trump can turn around by her performance here tonight. i'm steve handelsman, news4. >> reporter: all right, steve. we'll pick it up here from the floor of the quicken loans arena. states erupted in anger when they heard that thing about the rules and then the colorado delegation actually walked out. the message its sending is this party is not together. there's still a fracture within it. trump's campaign manager calls it not a movement but just a bunch of rogue delegates. when all of this is settled and convention is over, you have to get people to the polls. that's what tom has been digging into today.

virginia delegation breakfast both food and politics naturally on the menu at this republican convention. joanne chase of loudoun county is an official delegation guest and is proud of her trump for president button. >> i identify with donald trump. >> reporter: the native of puerto rico is on a mission for national coalition for diversity for trump to push back against protests and polls that show trump disliked in large numbers by hispanics for his anti-immigration rhetoric. >> my goodness. those polls are so incorrect. i speak to hispanics everywhere. what they do tell me is they do support donald trump. >> reporter: there are a few hispanic in the virginia delegation but chase says virginia republicans have a hard fight on their hands and need to curb party infighting. >> i'm hoping and praying that all delegates understand the importance of electing donald trump rather than hillary

done to jeopardize the support and the vote and the unity of the party for donald trump will be helping hillary clinton. >> reporter: coming up at 5:00, just how united is the virginia republican party here? in cleveland, tom sherwood, news4. >> reporter: that's just one of the questions tom is going to answer for you as he gets inside and behind the scenes with delegations from d.c., maryland and virginia. we'll send it back to you. >> chris lawrence on the floor there. chris, thanks so much. on the democratic side this week, we still don't know who hillary clinton will choose as a running mate. >> and virginia senator tim kaine isn't confirming or denying his position on clinton's short list. when asked if they had spoken about the vice presidency during their campaign event last week in northern virginia, the former governor told nbc news, "nope. we were talking about the rally and we were talking about

the latest nbc/"wall street journal" poll shows clinton with a nine-point lead over donald trump among virginia voters. this is the best time of year to spruce up your home and give it curb appeal. you want that paint job to last a while. consume e a rain jacket may be in order this evening. storm team 4 is on weather alert mode as we track this rough stuff. it's blowing through right now. maps are

but how did we end up here? his mom thought he had the flu and that he was covered by the meningococcal meningitis... vaccine he had received. until 2014 there were... no vaccines for meningitis b in the u.s. now there are. while uncommon, meningitis b can... lead to death within 24 hours. trumenba is a vaccine for 10 through 25 year olds to help prevent group b meningococcal disease. trumenba should not be given if you had a severe allergic reaction after a previous dose. most common side effects were injection-site pain, fatigue... headache, muscle pain, and chills. ask your doctor about... all the risks and benefits of trumenba and tell them if you've received any other meningitis b vaccines. meningitis b can be spread by typical sharing behaviors. a drink... a spoon... a kiss. it all started here... it might have been prevented with trumenba. ask your doctor about trumenba.

a fresh coat of paint on your house can make a difference but you want it to last. >> these costs a lot of money. we're talking thousands of dollars to paint your house. you want to get it right the first time. we're talking about top house paints. consumer reports tested popular paint brands that show for a variety of prices to find out which ones last

sure. that color you agonized over looks great but will it hold up over time? >> you want a paint that stands up to elements, sun, rain and snow and resists dirt and mildew. >> reporter: that's why consumer reports designed tough tests. exterior paints are placed on the roof of the consumer reports testing headquarters. they're left up on the roof. conditions are so harsh that one year of exposure simulates three years on a wall, door or fence. boards are inspected to see how long they resist cracking, fading, dirt and mildew. >> after three years of exposure on our roof, still has no cracks. dirt and mildew. still intact. >> when you compare it with this paint, you can see the difference. after three years, it's cracking and starting to flake off and this one isn't even the s

>> after one year, just got lighter. after two years even lighter and after three years it changed to a completely different color. >> consumer reports found just two paints to recommend. behr for $40 a gallon and clark and kensington for $35 a gallon. either paint should last about nine years on your house. that's a long time. consumer reports says flat paint with dull finish looks best on exterior walls older and more weather warn. the best time to apply paint, during the day when temperatures are between -- this was surprising -- 50 and 90 degrees with no wind. any mornings this summer would work. >> i wouldn't have thought that. >> even the rain. i would say probably stay away during that time. >> when they're changing the colors like that, that's

dramatic. >> thank you. we have new details coming in about the story that has the nation in shock still. what we're learning about the man who targeted three police officers when we take you live to baton rouge next. >> reporter: parents hugging and kissing their kids good-bye as more than 200 youth from northern virginia prepare to head off to europe for a pilg m pilgrima pilgrimage. we'll look at security concerns ahead of their travel. weather alert. we are tracking storms that are moving through the city right ow.

>> reporter: i'm chris lawrence back on the floor of the quicken loans arena. i can tell you from talking to people here, it's a start to a convention unlike any other. if the republican party was hoping to present a united front after its disagreements, that's not how this

just in the last 30 minutes ago as decisions about rules and nomination committee were read, we saw colorado delegation walk out. virginia erupted in boos. again, this is still a party trying to come together. it's something that i'll be diving into with nbc's chuck todd coming up in the next hour. for now, i'm going to sign off from down here. we'll hustle back upstairs and give you a completely different view of the convention here at quicken loans arena. >> things are getting hot in cleveland. the message in baton rouge today is one of resilience. the community is standing together as it mourns the deaths of three officers killed in that ambush yesterday morning. >> just moments ago we got an update on the accused gunman as another round of deadly violence centered around policing and race rocks our country. >> reporter: police say that

specifically targeting officers even after he was killed by police they found three guns on him which are now being analyzed for ownership. local leaders say with many people on edge here in baton rouge, they're not going to let the latest shooting keep them living in fear. a mission to kill police carried out in baton rouge leaves a community reeling and searching for the reason the lone gunman, 29-year-old gavin long opened fire. his victims, six officers, three of them laid dying in the sunday morning ambush. >> there's no doubt whatsoever that these officers were intentionally targeted and assassinated. >> reporter: now a new glimpse into who the former marine is. an avid social media user who called himself cosmo and posted comments about killings by police officers and murders of those in dallas. >> a lot of moving parts. a large puzzle. >> reporter: overnight federal agents scoured his kansas city, missouri, home for

a possible motive. long served a term in iraq working as a computer specialist and trained with weapons. sunday his gunfire reeked havoc causing officers montrell jackson, matthew gerald and brad garafola. all three husbands and fathers. >> they ran towards danger in order to protect the public. >> reporter: local leaders say they're not going to let this tear their community apart. >> we are resilient. we'll come back even stronger. we're not going to let the city be defined by violence we've seen. >> reporter: a city now dealing with its second instance of violence in mere weeks. investigators say this is far from over. they're going to be looking at long's car rental to figure out everywhere he went and delve deeper into his social media posts because we're told even after he was killed by police, someone else was still posting online for him, which is why st

priority to try to figure out if he may have been working with someone else. reporting in baton rouge, sarah rosario, news4. storm team 4 weather alert day. i want to show you what's going on. this is outside dulles. a lot of ponding on the roadways but most of the rain -- seeing it light right now. east of i-95, national harbor had heavy rain blow through the region. these storms are moving quickly. again, we will see them lighten up throughout the area once they move past the region. after about 6:00, 7:00, 8:00, storms will push east and maybe just a few stray showers and an isolated storm as we get into the overnight. we'll clear through your tuesday afternoon. all right. the latest. still have that severe thunderstorm watch. that's in pink. the national weather service is starting to trim that back. that will go until 8:00. my gut tells me they'll expire that quickly. severe thunderstorm warning has now been canceled for the

william and northern culvert county. i'm sure those go until 5:30. look at where this line of storms is right now just coming through annapolis and then right to the south and west of the district. the district inside the beltway now just getting heavy to moderate rainfall but it continues to lighten up because you can see back edge of that precipitation starting to move through here. we'll see these. headed toward prince frederick after 5:39. i believe that threat will be over after 6:00 tonight. then we rain cool. once the storms roll through the area, temperatures dropping about 20 degrees. they'll go up a little bit and we'll end up in the 70s during the overnight. we have a few showers and thunderstorms during the overnight and maybe tomorrow morning. heat building once again tomorrow afternoon and maybe a shower here or there tomorrow afternoon. i would say about a 30% chance. a mix of sun and clouds. by the time we get into wednesday and thursday, looking good. we're still at 90 degrees mo

your wednesday and thursday upper 80s to around 90. humidity drops. it's going to be comfortable. we still have warnings out there just east of i-95 going until 5:30 but most of these storms moving out of here pretty quickly. >> that's good news. i was promised a pool day at some point this week. thank you, lauren. all right. today a vietnam war veteran was awarded the nation's highest military decoration. the medal of honor. >> charles kettles is credited with changing lives of 44 soldiers during an ambush back in 1967. he flew his helicopter in and out of a heated battle three times. after the last trip, he learned eight soldiers had been left behind. kettles returned to the battlefield without artillery or air support and rescued them. during the ceremony at the white house today, president obama said kettles' bravery is a great inspiration. >> the instant he got airborne, another mortar
