a.m. this morning with a burst of gunfire. the gunman confronted by a police officer on the scene. at around 5:00 a.m., they went in in a rescue situation because hostages had been taken. the police reporting up to 30 people may have been spaichd the headline, this is being treated as an act of terror. >> absolutely, george. an incredible scene described there. shootout at the nightclub. using a bear cat to crash through the wall. hostages taken. 20 people dead. they'll use every available tool to run this down. that struck me. the fbi stating that the suspect appears to have radical islamic lanings. they're investigating that. they want to know if this is a lone wolf situation. do they have ties overseas? every tool will be used to l

so many dead, so many wounded. >> they're not prepared to say whether that person was a citizen or not. they're saying they believe there is no credible indication there is any threat anywhere else, in orlando, florida, or anywhere else in the country. they have no indication of that. one of the other things we learned from the briefing is that this gunman, very well prepared. assault rifle. handg handgun. and some kind of suspicious device. on his person. perhaps in his care. >> it was clear this morning according to sources this person put a lot of time and effort into the kargt and what he was going to do. law enforcement officials, again, because of the scale of this. because of all those people shot, thats a one of the reasons they're looking at this as an act of domestic drichterrorism. we're told by source they have a pretty good idea who this is. they're running

to get a better picture of whether this person had support. >> let's go to brad garrett. former fbi special agent. it sounded like a dramatic scene beginning to unfold around 5:00 a.m. when the police decided to go in with their bearcat and try to take over and end the situation. >> it's one of those situations george, where you have to make a call at a certain point to save lives. think about this, now, maybe three hours into the shooting, we still don't know how this played out. did he come out once, engage the officers, go back in and shoot again then barricade himself? all are unphone known at this p. you have to be decisive if you're the on-scene commander as to when we're going to stop this. nobody else is going to get hurt. >> i want to go one more time to lauren lyster. the

back with more information as they got it. what's happening now? >> reporter: sure. we heard about the possible 30 hostages or people rescued. we did see a few minutes ago, a long line of people mostly men walking down a street that is within this crime scene area. we certainly can't get to this. boarding a bus. and then taking that bus down towards downtown orlando. now, we don't know if these were hostages. or if these were victims. this is what's going on at the scene. we have seen fbi go into the scene as well. there's still a police presence here. it's not what it was in the middle of the night, early in the hours of the morning. still a police presence. interesting, at 5:00 a.m., them saying that that's when they decided to go ahead and begin that hostage rescue. and use an explosive entry. that's right when the time we

explosion. the orlando police say it was a controlled explosion. the police and authorities talked about that shootout and taking out the gunman and 5:15 a.m., around that time is when we heard, there had been silence before. we heard a barrage of gunfire. we saw a number of first responders rushing back and forth between the scene and the the hospital. that's the latest we can tell you. we did have people that were here from the nightclub and police took them to police head quarters. they're asking every one that was there to go to police head quarters. this scene has been cleared out of folks in the nightclub, to our knowledge. just down the street, down the way, at the end of the block is the hospital where some of the 42 people have been transported. it's very close. just at the end of the block. this is the one that's been on lockdown since 2:00 in the morning, right at the time of the shooting. this is where family and friends have been

>> okay, lauren lyster, thank you very much. reports of just a terrifying scene overnight in orlando, florida. shooting and hostage situation. aproximal matly 20 people dead. that would make it the worst terror take in america since 9/ 9/11. for now, returning to our regular programming. for many of you, that's "good thought, what am i going to do? it is a little bit unfair but all of my friends started having kids and you see from the other side how difficult it is for moms going through this and how it's not easy at all. they are doing two jobs. and i don't feel that way ht?more. i'm gonna buy them. thinking? >> yes. i've heard from people dealing with this, too, and they are like, it is unfair. i think there is a sentiment of that. >> the addition of social media and the internet makes

more viralant place when you hit a controversy or a nerve like that. >> why hyes. it was frustrating because the story didn't reflect what i feel but i can understand where moms and people were coming from when they were attacking but at the same time, when you don't see the effect your words are having on the person, it makes it easier to hit send and that's a little difficult and i think maybe before, assuming somebody feels a certain way, maybe you might want to ask them. >> do you think everybody deserve as break from work at some point? >> i don't think people deserve a break necessarily but i think it can be a positive thing. like if you can make it work for yourself or talk to your employer and figure out because you created a great track record for yourself and i'll come back way more creative and productive, it can be a good thing. >> what are you doing now? >> i'm trying to work on my next book. >> any ideas that you can throw out at us? >>

ironically, one of the characters in this book, i was fascinated with her friend bree so i'm going into her life and seeing what she's dealing with. it's about a single woman trying to find love. >> i think you made a lot of people think. thanks for coming on. >> thank you for having me. now here's a look at what is making news as we head into a new week "on the money." oil prices bubble to a new high. crude oil above $50 a barrel because of falling supply, increasing demand and weaker dollar. ka nadier territory was responsible for the rising prices which pushed stocks up in the middle of the week. the market seems to like higher oil prices. the dow closing above 18,000 for the first time since april. the nasdaq and s&p 500 hitting the highest levels since 2016. stocks fell on friday. if it can happen to him, it can happen to anyone. mark zuckerberg had some of his social media accounts hacked

he used the same password for them. it was da, da, da. we're guessing he won't be using that again. up next, we're "on the money." seeing the future. a new experimental medicine that may prevent these children from going blind. and later, are you ready to buy a new car? you better make sure you check your credit report first. why someone else's money mistakes could ruin your deal. take a look at how the stock market ended the week. we were born 100 years ago into a new american century. born with a hunger to fly

better. and what an amazing time it's been, decade after decade of innovation, inspiration and wonder. so, we say thank you america for a century of trust, for the privilege of flying higher and higher, together. ♪ jill: the swedish defense

talking about nato strategies and the potential shift in israel alliances. a new type of medicine is approaching the markets that sounds like it came from a science fiction novel but it

came from a lab by targeting the underlying cause. meg is joining us. it's pretty interesting stuff. >> it's re, really cool. as we learn more about genetic, companies are turning that knowledge into more effective treatments. we met one family whose kids are some of the first people to try this. >> let me see that. >> reporter: caroline and cole carper have been through more of your typical siblings. >> i can't imagine it being any different than the two of them being together and going through this together. you know, they've had to learn braille together and gone to school for the blind together. >> reporter: they were both diagnosed with lca, a rare retinal disease. >> the doctor really said there's nothing -- there's no medical treatments at this time. >> reporter: both caroline and cole were expected eventually to go blind. but their parents found an experimental treatment and two years ago, the kids enrolled together in a clinical trial.

biotech company formed out of the research of children's hospital of philadelphia. >> the idea is we're taking the correct functional copy of the gene and adding it back into the cells that have dysfunctional or missing copy of that gene or blueprint. >> reporter: it's called gene therapy. and it's relatively unchartered territory medicine. the technology uses a modified virus to deliver a healthy copy of the gene to make up for one that causes disease. scientists have been working on it for decades. but only now are the first gene therapies approaching the market. spark is the most advanced. once they are in place, they are designed to do the work of a normally functioning gene, meaning patients only undergo treatment once. in trials of 41 patients, the therapy has shown to improve both vision and light sensitivity with no major side effects. caroline and cole were no exception. before their surgerie

kids had trouble seeing in low light. now, though their vision is not perfect, they say they are noticing big differences. >> good things are to come. >> it was snowing and i'm like, oh, i can see the snowflakes. it was really cool. to actually see something i've never seen in my life before. >> reporter: spark is one of several companies developing gene therapy targeting everything from sickle cell disease to other disorders. if successful, it will be a new paradigm, fighting genetic disease in one treatment. >> i thought it was really cool, how simple it was and how it changed my life. >> so patients only have to receive one treatment. spark is so committed to this idea, it chose once, or o.n.c.e. as its stock ticker. it's getting

this treatment. >> this is amazing. watching those kids to suddenly be able to read, that's amazing. >> he was a braille champion before getting this treatment. it was really incredible. >> when you talk about a one-time treatment, that's phenomenal for the patient receiving it. a lot of times you're going after the drugs that will give you the most money and the most return and that tends to be the ones treated as chronic illnesses. how do they price something like this when it's a one-time treatment? >> that's the biggest question because a lot of rare diseases you're paying $300,000 per patient for the rest of the patient's life. for something given once, do you pay a one-time cost of $1 million up front or do you spread that cost out with new economic models that we haven't even tried before in the drug industry? so this is all being talked about right now. >> it's amazing to see the progress that they've made. it sounds like it's out of science fiction. >> it does.

if you're planning on making a big purchase or changing jobs anytime soon, make

check on your credit report first. the detailed history of your borrowing and spending is often looked at by employers or big banks and if you have bad news on it, it's bad news for any of those. if you don't know where to begin, don't worry, sharon epperson is here to explain. what is a credit history, what is a credit report and how do you go about checking on your own? >> a lot of people know that their credit score is something that a lot of lenders will look into. what goes into that is the history on your credit report. that includes credit card account balances, your loans, mortgage, sometimes rental information will be on there as well as any bankruptcies you must have had and any negative items you might have had. even a collection on a library fine could be on your credit report. >> what? >> as someone who knows that that ha

>> you, right? how far back does the credit history go? where would i go about checking it? >> negative information is on there for seven years. really all you can do is pay your bills on time and wait it out to make sure that has less of an impact. you want to go to the three major credit bur bureaus. go to annualcreditreport.com. get a copy from each of those agencies once a year, once every 12 months. >> for free? >> for free. >> if you find any errors, things that are you pretty sure are not yours, what do you do about it? >> circle the errors and get the supporting documents to dispute why they are errors and then you need to contact the credit reporting agencies, let them know about it as well as the what if you find bad information and you realize it is you, the library book that you

>> you have to fix it. you can fix it yourself and perhaps go to a credit repair service if you think that they can do a job for you that's going to be a legitimate job. don't get scammed by some companies out there that say they are going to fix it, make it go away right away because that's not really possible. >> how do you know a scam from the real thing? >> i think it's best to try to do it yourself first. that's the best rule of thumb. there are websites that will rate credit repair services but it's better to do it on your own. also, if they say they are going to try to change your identity or help you change your identity, that's something to be aware of. if they cause you an up-front fee, pay this and we'll fix it for you, that's likely a scam. >> sharon, thank you. >> sure. up next, "on the money," a look at the news for the week ahead and the mountain climbers facing a life-changing decision near the summit of the world's tallest peak. >> you're there and you're like

uncontrollably. there's no question, i had to turn around and come down because this is more important. life is more important. >> i give you massive kudos for recognizing that it was something that you needed to turn around. that must have been really difficult. >> it was. it's something i'm going through now, feeling that and knowing i made the right decision but i failed on the mountain. >> corey, you made it to the top with no oxygen which is something fewer than 200 people have pulled off. what for you was the most striking thing, the scariest thing, the most concerning thing along this journey? >> the hardest part for me was adrian turning around and for a number of reasons. a, you've spent all of this time being with your partner and investing so much time into the climb and then they leave and that put me in a position of being alone on the mountain in the dark in a storm and that's very scary. but the hardest, you know, sort of -- i guess the most striking thing for me is

actually had. i was there for three minutes and then i was gone. >> few months to climb there. >> yeah. and really a whole lifetime of investment into climbing and thinking about this and wanting to do this and then you are there and you're like, i'm scared and i want to leave. >> you brought the world along with you with snapchat. people were really able to see and it was an unfiltered view of what was happening. >> it really felt like an experiment for us. snapchat posts right away. it's instant and i just loved that because i think a lot of people don't understand what it takes to climb everest. >> was that motivating along the way? >> i think, yes. absolutely. especially on summit day, there is an element of like -- you know, i don't want to say the world's watching but it kind of feels good to have people who have your back and they are invested and excited. >> adrian, you've been doing mt. everest many times. how many times to the

years. >> when is enough enough? >> when is enough enough? >> you know, i'm not sure. i truly love the human struggle that happens on everest. so clients with supplemental oxygen, they push their bodies so far. it takes so much mental strength. i love watching that. and that's what i really felt this year, like finally finding that point of failure and being broken by the mountain. i loved it. >> but you're going back, right? aren't you going back with oxygen? >> i certainly want to try. >> is this just a way of life for you at this point? >> it is a way of life. i've been spending seven to eight months a year living in a yellow tent on mountains on the planet in the last 20 years. certainly it's my way of life. >> i just think there's a misunderstanding that once you do something, you stop. you reached the

especially people who are very passionate about climbing big mountains, there is no box. it's a motion through life that continues to give. >> and i just want to say congratulations to both of you. we're glad you're here safe and we look forward to hearing of your other adventures. thank you both. >> thank you so much. that's the show for today. i'm becky quick. thank you for joining us. next week, how to keep your pets safe and healthy this summer. each week, keep it right here. we're "on the money." have a great week and we'll see you next weekend.
