nbc 10, thanks for watching. i'm renee chenault-fattah. the news tonight continues with "nbc nightly news." on our broadcast tonight, boots on the ground. did the nation's top military officer just open the door to the possibility of american combat troops in this fight against isis despite what the president told the nation? without warning. wildfires explode in california engulfing entire neighborhoods as some families escape only with what they were wearing. money talks but will the nfl listen? along with their customers, now some of the game's biggest advertisers starting to weigh in. and legal weed in colorado where they can't grow it fast enough to keep up with demand, but there have been some scarce along the way that other states are now watching. "nightly news" begins now. >> announcer: from nbc news world headquarters in new york,

this is "nbc "nightly news"" with brian williams. >> we begin with men and women in the u.s. military being sent off to serve overseas on two big fronts. today the president said he's sending up to 3,000 americans into africa to join in the fight against ebola, an enemy they cannot see. but first to an enemy operating out in the open. this fight against isis and the debate that broke out again today was whether or not the u.s. can truly avoid putting troops on the ground. it's where we begin tonight with our chief foreign affairs correspondent andrea mitchell. >> reporter: is this the beginning of mission creep? the president's top general today opening the door to requesting american boots on the ground against isis. >> if we reach the point where i believe our advisers should accompany iraq troops on attacks against specific isil targets, i'll recommend that to the president. >> reporter: and this. >> if there are threats to the united states, then i, of course, would go back to the president and make a recommendation that may include

the use of u.s. military ground forces. >> reporter: but the president has repeatedly promised no boots on the ground. >> these american forces will not have a combat mission. we will not get dragged into another ground war in iraq. >> reporter: and telling chuck todd on "meet the press" -- >> the notion that the united states should be putting boots on the ground i think would be a profound mistake. >> reporter: general dempsey even told congress u.s. troops could be embedded with iraqis on complex missions like retaking mosul. and he said it could take a year to train only 5,000 syrian forces to go up against isis in syria. something critics in both parties say should have been done two years ago. >> was the president right in 2012 when he overruled his secretary of defense, secretary of state and director of the cia and refused to train and equip the modern opposition forces in syria, which, according to your testimony, we're doing today? >> senator, you know that i recommended that we train them.

>> reporter: isis isn't waiting. today in a propaganda video claiming it shot down a syrian war plane, a claim nbc news cannot verify, and two branches of al qaeda tweeted a rare joint message. urging warring militants in iraq and syria to stop the infighting between you and stand as one rank against america's campaign. even as the u.s. escalated its air war, striking isis targets near baghdad. the white house quickly said that general dempsey's comments were only hypothetical. and under pressure from the white house, tonight dempsey's spokesman said american combat forces are not required now, but he repeated if the situation calls for combat troops, he will ask for them. >> andrea mitchell starting us off tonight. thanks. now to the second front, this fight against ebola, which as of today became a military matter. as we said, up to 3,000 american military personnel will be deployed into this hot zone in africa at a starting cost of

$600 million, all of it to combat an outbreak the world health organization called today, quote, unparalleled in modern times. we get our report tonight from our chief medical editor dr. nancy snyderman. >> reporter: the images from west africa are searing. children alone in the streets, men collapse and left to die. with ebola now spiraling beyond a health crisis and into a global security threat, president obama said the united states must do more. >> ebola is now an epidemic of the lines we've not seen before. >> reporter: and so the administration announced today operation united assistance, sending 3,000 troops including medical, engineering and security forces. building 17 treatment centers in liberia, shipping 10,000 sets of protective equipment and supplies. training healthcare workers and assisting with security. >> we've done it in haiti several times. we've done it in south america, we've done it in africa before,

we've done it in southeast asia. >> reporter: but this is an infectious hot zone. >> that is unprecedented. i can't remember a time when we sent troops to do this particular mission. >> reporter: u.s. forces will not have any direct contact with ebola patients, but they will be dealing with people who are scared and suspicious of outsiders offering to help. so the question remains -- who's really in charge? >> the russians the cubans, japanese, chinese, ugandans, canadians, europeans all working on this issue. who will take control? >> reporter: the virus is spreading much faster than efforts to contain it. researchers suspect the epidemic started last december with one case in guinea. now there are nearly 5,000 cases in five african countries. some experts predict that if we don't get control of the virus, the number of infections could mushroom to nearly 55,000 by next month. today ebola survivor and missionary dr. kent brantly met with the president before

testifying before congress. >> i witnessed the horror that this disease visits upon its victims. this is not simply a matter of providing humanitarian aide, it is very much a national security concern. >> reporter: the death toll has climbed to over 2500 cases. if there is a silver lining in this epidemic, it may be that we're finally talking about a real commitment to improving fragile healthcare systems in africa and around the world. >> a national security concern. that's a takeaway quote. now to a state of emergency in california where a dozen wildfires are exploding including one so ferocious it torched half of a town turning neighborhoods into ashes. our own miguel algagger is in the community of weed, california, north of reading, prepared to show us the accident of the devastation there. >> reporter: good evening. this is the biggest neighborhood in weed. we are just off of oak street. it's an eerie example of what we

saw over and over again today. just yesterday children were playing in this front lawn, their toys are still tossed everywhere. now home after home obliterated. 45-mile-an-hour winds. 100 structures, nearly a quarter of this small town, was damaged or destroyed. 1500 people scrambled to get out. >> horrendous. absolutely just devastating. >> reporter: tammy gonzalez ran to evacuate children from a nearby school. as flames barreled down on them. did you think you were going to make it out alive? >> at one point, no. >> reporter: with smoke choking this community of 3,000, it wasn't until today that the full scope of the damage became clear. the holy family catholic church is where corey rodriguez was baptized. >> it's like out of a movie, mm-hmm. sprnl a church where i used to come like every sunday, yeah.

>> reporter: just across the street, the lumber mill, a major employer for the town was fuel for the fire. >> like a firestorm. >> reporter: the bernstein family lost the home their children grew up in. >> a lot of this, you know, just the sentimental stuff is what can't be replaced. >> reporter: at 4,000 feet we can still see hot spots on the ground. this fire is still very active. it could change direction and attack homes at any moment. tonight california's fire season is in full swing. near sacramento, tense moments when a crew of 12 deployed their fire shelters as flames overran their position. >> we'll need to give them support to get out of there. >> reporter: the crew rescued, no injuries, but a close call. but in this small town, the damage is done. everyone knows someone who lost something. >> people's lives are ruined. this town, i don't know if they're going to be able to recover from this.

>> reporter: recovering is hard to imagine when you see so much destruction in such a small place, so many people we spoke to tonight say they're not sure if or when they will rebuild. if there's any good news, this place is roughly 20% contained, but brian, it will cost tens of millions of dollars to clean up and rebuild. >> what an incredible scene there in weed, california, there tonight. well to the south of you in the baja peninsula tonight, herculean effort to clean up after hurricane odile turned places like cabo san lucas into disaster areas. tonight as the remnants of odile move into the continental u.s. millions in the american southwest are bracing for more dangerous flash floods now. weather channel meteorologist jim cantore is in tucson for us tonight. hey, jim, good evening. >> reporter: good evening, brian. the loss that you see behind me here was three-quarters full and flowing rapidly as a result of last week's flood, and they're hoping for not a repeat of that

with this one. unfortunately, all signs is of the atmosphere point to that. as a matter of fact even today in mesa they were handing out sandbags, something they rarely do in the desert where you get less than ten inches of rain. and that's hoping to avoid, obviously, situations like we had last monday in mesa. i mean, we're talking about tremendous flooding. tucson, phoenix, record rainfall there. as you can see, water rescues all over the place. the track brings the remnants right up into arizona. very rare we're in the cone here. roswell, albut keerky, four to ten inches, something they would normally see in a half year. >> jim cantore, tucson, amazing situation, jim, thanks. we turn to trouble in the nfl and some new voices joining in this nonstop criticism of the league, its players, policy and management. while it's true the commissioner roger goodell works for the owners, increasingly the customers and the advertisers are being heard as more details

in this scandal come out every day. we get the very latest tonight from our national correspondent peter alexander. >> reporter: challenging ray rice's indefinite suspension, the nfl players union is filing an appeal tonight on behalf of rice. a union representative tells nbc news they believe there was not a fair and impartial process before the decision to suspend rice indefinitely and they'll ask commissioner roger goodell to recuse himself from overseeing the appeal. >> he has enormous power, enormous discretion, so the very fact that the union is asking him to step aside is a fairly direct challenge. >> reporter: today the minnesota vikings adrian peterson returned home from the team's facility telling nbc news he plans to practice with his teammates again tomorrow. while the star running back disputing charges that he recklessly injured his 4-year-old son while disciplining him, vikings hall of famer fran tarkenton said he was embarrassed by the team's decision the allow peterson to resume playing. >> we're trying to do the right thing. >> reporter: hours after its

logo appeared behind the vikings gem manager, radisson suspended its sponsorship of the team. first sign of erosion from the corporate sponsor spending 1 billion a year. the league's response, we're taking action. >> it is like an aircraft carrier hitting a mine, yes, it blows a hole in the hull but it keeps on sailing and in a few months you won't notice that the hole was there. >> days after cbs sports yanked a rihanna song from its broadcast, the singer blasted the network tweeting, you all are sad for penalizing me for this. cbs responded, pulling rihanna's song permanently. the nfl deciding the best defense is a good offense today drafted another woman to head up its response. her name is cynthia hogan. she's a former aide to then-senator joe biden who helped spearhead the violence against women act. >> so it goes in the world of

professional football tonight. veteran nascar driver tony stewart has returned to the track since that accident that claimed the life of another driver kevin ward jr., in that dirt track race in upstate new york, but he learned today his legal troubles are hardly over and may indeed just be starting. the local d.a. said he will give the case over to a grand jury to decide if stewart should be charged. the prosecutor there could have dropped the charges on his own, could have dropped the case entirely but chose to let it proceed. still ahead for us tonight, edible weed. as the pot business booms in colorado, one particular part of the industry has other states keeping close watch. and later, fresh confirmation of what some veteran married couples have known for years. there may indeed be a secret to wedded bliss. so i can reach ally bank 24/7, but there are no branches?

24/7 it's just i'm a little reluctant to try new things. what's wrong with trying new things? feel that in your muscles? yeah... i do... try a new way to bank, where no branches equals great rates. this is kathleen. setting up the perfect wedding day begins with arthritis pain and two pills. afternoon arrives and feeling good, but her knee pain returns... that's two more pills. the evening's event brings laughter, joy, and more pain... when jamie says... what's that like six pills today? yeah... i can take 2 aleve for all day relief. really, and... and that's it. this is kathleen... for my arthritis pain, i now choose aleve. get all day arthritis pain relief with an easy-open cap.

multiple medications, a dry mouth can be a common side effect. that's why there's biotene. it comes in oral rinse, spray or gel, so there's moisturizing relief for everyone. biotene, for people who suffer from dry mouth. before we craft it into a sandwich. the amazingly tender roasted turkey -- always raised without antibiotics, the zesty cranberry mostarda, the freshly baked flatbread... but here's what you don't always see. the care and attention that goes into it. because what matters most is the simple, delicious ingredients that make up the whole delicious meal made just for you. and this is our turkey cranberry flatbread sandwich, paired perfectly with our autumn squash soup. only at panera bread. the state of colorado would likely like a word with all the other states that are considering going down the path of legalizing marijuana, and in a word, it's caution.

it's been a game changer in colorado where adults can now grow and buy and consume something illegal under federal law. it is a huge statewide industry, but there have been some problems. we get our report tonight from nbc's harry smith. >> reporter: every thursday night there's a party at grove big supply, free drinks, music and dances, even a mace to smoke. it's a way of saying thank you to the customers for making grow big a giant in the pot growing supply business. because in colorado these days, you can grow your own. >> an entry level kit to get into your garden, under 300 bucks. >> reporter: recreational and medical pot sales in colorado have soared past $300 million in just the first six months of the year. pot entrepreneurs like andy williams can't grow weed fast enough. he describes his store, called medicine man, as the costco of pot. all of this weed that you

grow -- and there's an awful lot of marijuana here -- >> yeah wrrt where does it go? >> we sell it out of our store. we don't wholesale anything. we grow 100% of what we sell out of our front end. >> you are clear for takeoff down runway 420. >> reporter: but if the high rolling marijuana business has hit a bump, it's edibles. >> very different from smoking. it takes a lot longer through the body. >> reporter: some first-time adult users have said edibles have made them paranoid and ha lusen tory. they've gotten into the hands of small children. this is crazy. because if you have this in your house and your kid got hold of this stuff -- >> that's the thing about weed, the kid won't know that it's medicated. >> parents need to know and be aware that this stuff is not harmless for children. >> reporter: dr. sam wong works in the emergency room at colorado's children's hospital. >> the worst scenarios we've seen are kids actually unable to be aroused, in a coma for all

intents and purposes. a couple kids that needed to have a breathing tube put down. >> reporter: actually intubated. >> intubated that's correct. >> reporter: wow. bob of ip credible edibles says the industry and the state are working together to make edibles safer. >> we need to now mark these so that people looking at them will know this the cannabis. >> reporter: but he says there's only so much the manufacturers can do. >> eventually the responsibility has to fall back on the consumer to make sure that they keep it in the child resistant package and they keep it out of the hands of children. >> reporter: which one would think is a matter of common sense. harry smith, nbc news, denver. we're back in a moment with a big announcement late today about america's new mission to space. ♪ walgreens knows that heartburn sufferers can sometimes find themselves at the corner of "mmm, home cooking" and "umm, i think that's enough." that's why walgreens offers new nexium 24 hour,

we have an update tonight as part of our coverage on poverty in this country in plain sight. tonight the first good news in a long while in the fight against

poverty. the poverty rate in the u.s. has dropped for the first time since '06. mind you, there are still 45.3 million people living in poverty in this country. that includes nearly 20% of our children, and that's the lowest level since 2000. nasa announced late today it's awarding a dual contract to two company, boeing and spacex to build a rocket to take american astronauts into space and on to the international space shuttle. a couple of points to remember here, sending americans into space is what nasa used to do until the shuttle program was stopped three years ago. these days we pay the russians for rides on board the soy urkz z. relations with them is strained. jay barry who has covered every manned space flight says this is good news indeed for nasa. >> this announcement tells everyone here that they're back in the game, their morale will be lifted and they'll be headed

down the road back in space on our own vehicle. >> truth be told, the nasa rockets of old were the product of many different venders. now two big names will split that job. speaking of space, if you live in the northeast think back to sunday night around 11:00 p.m. eastern time. did you notice anything unusual? we now have the video, this one shot from manhattan looking west toward new jersey shows a confirmed meteor which prompted a number of sightings and calls to police. this one was visible from new england south to virginia. the good folks at the american meteor society put out this map showing where all the sightings were reported and concentrated. they called it a random fireball event. the truth is they happen every day. most burn up to a crisp and many of them go unseen due to daylight. and if looking skyward you see what appears to be a flying highlighter, it's just spirit airlines' new look. paint schemes are called livery in the flying business. southwest and frontier just

changed theirs, and a "usa today" writer has politely called spirit's new livery scheme flamboyant. when we come back on a tuesday night, something some spouses have been saying to the others for years. and now the researchers tell us it's true. so ally bank really has no hidden fees on savings accounts?

that's right. it's just that i'm worried about you know "hidden things..." ok, why's that? no hidden fees, from the bank where no branches equals great rates. you know.... there's a more enjoyable way to get your fiber. try phillips fiber good gummies. they're delicious and an excellent source of fiber to help support regularity. mmmm. these are good! the tasty side of fiber. from phillips that's the way i look at life. looking for something better. especially now that i live with a higher risk of stroke due to afib, a type of irregular heartbeat, not caused by a heart valve problem. i was taking warfarin, but wondered if i kept digging, could i come up with something better. my doctor told me about eliquis... for three important reasons. one, in a clinical trial, eliquis was proven to reduce the risk of stroke better than warfarin. two, eliquis had less major bleeding than warfarin.

and three, unlike warfarin, there's no routine blood testing. don't stop taking eliquis unless your doctor tells you to, as stopping increases your risk of having a stroke. eliquis can cause serious and in rare cases fatal bleeding. don't take eliquis if you have an artificial heart valve or abnormal bleeding. while taking eliquis, you may bruise more easily and it may take longer than usual for any bleeding to stop. seek immediate medical care for sudden signs of bleeding, like unusual bruising. eliquis may increase your bleeding risk if you take certain medicines. tell your doctor about all planned medical or dental procedures. those three important reasons are why eliquis is a better find for me. ask your doctor today if eliquis is right for you.

finally tonight, while no two marriages are alike, you would have thought they didn't need a study to confirm the secret to a happy marriage. but they have done it. turns out there's proof of what a lot of married men have been saying for years. we get our report tonight from nbc's kate snow. >> reporter: the saying has been around so long it's hard to know who started it. >> happy wife is a happy life. >> happy wife, happy life. >> happy wife, happy life. remember that. >> reporter: the whole theme immortalized in movies. >> the man is the head, but the woman is the neck. and she can turn the head any way she wants. >> reporter: but actual science? that's the new part. researchers at rutgers and the university of michigan looked at 394 older couples married an average of 39 years. turns out husbands get an extra special lift in life satisfaction when their wives are happy in the marriage. >> even those men who in their

own eyes saw their marriage as not that great, if the wife views the marriage as really great, that would enhance his overall happiness. >> i agree with that. the wife has to be happy. >> if she's happy, it makes -- we're all happy in the family. >> reporter: we did our own unscientific survey all over the country today. >> how long are we married? >> 27 years. >> we've been married 48 years tomorrow. >> 24 years. >> reporter: so what are the ingredients for a happy marriage? >> be willing to give more than you take. >> there's always going to be a storm. there's always going to be rain. however, the secret is dancing in the rain together. >> and not working the same shift. >> that helps a lot. >> yes. >> reporter: yes, the science points to differences between husbands and wives, but a lot of people today echoed what the researchers called the biggest lesson of their work -- happy family equals happy life. >> i love ya. >> yeah, okay. >> okay. >> reporter: kate snow, nbc news, new york. >> and that is our broadcast on a tuesday night.
