"nightly news" begins now. >> announcer: from nbc news world headquarters in new york, this is nbc

"nightly news." reporting tonight, lester holt. good evening. our top story is breaking as we come on the air. a suspected accomplice in the new york prison break is now under arrest. joyce mitchell, a prison worker who police say may have developed relationships with both escaped cons, is to be arraigned this evening after she apparently began spilling more details of romance and forbidden items supplied to the men. as for the search for the prisoners themselves, it's been a day of more tantalizing hints and bursts of police activity as anticipation grows that police are drawing closer to their prey. we have it all covered. nbc's ron mott starts us off with this breaking news. ron? >> reporter: lester, good evening to you. joyce mitchell is being held tonight at the state police barracks in malone, new york. that is near her home. she will be arraigned on two counts, one a felony, the other a misdemeanor. now, the felony is for promoting prison contraband. the misdemeanor is for criminal facilitation. and that felony charge

carries a possible prison sentence of one to seven years. under questioning by law enforcement all week about what role she had in the escape, tonight, nbc news has learned joyce mitchell has been arrested and charged in connection with the prison break, helping richard matt and david sweat escape last weekend. the district attorney said mitchell, a civilian employee in the tailor shop, provided contraband to the prisoners. >> she has not brought power tools into the facility, based on our investigation, prior to saturday. >> reporter: d.a. andrew wylie said initially, mitchell only offered minimal information, but as questioning progressed, she provided more details. the d.a. confirmed prison officials had previously opened a formal investigation of her relationship with sweat, concluding there was insufficient evidence to warrant disciplinary action though said the pair were separated for a period of time. earlier, authorities reported mitchell told them matt made her feel special. the clinton county d.a. told cnn today that joyce mitchell's husband, lyle, is being investigated and could have been involved or at least had knowledge of the breakout. despite her alleged involvement,

mitchell's son told nbc's stephanie gosk this week he believes there's more to the story. >> that doesn't make any sense to me. she is not the kind of person that's going to risk her life or other people's lives to let these guys escape from prison. if she was involved in anything, you can rest assured there was a good reason for it and there's more to it than a relationship with an inmate. >> reporter: tonight, investigators say they're looking into the possible involvement of even more people inside this prison, lester. >> all right. ron mott with the new developments. now to the hunt for the men mitchell's accused of helping still on the loose after nearly a week on the run. nbc's miguel almaguer is following the manhunt for us. miguel, what's the latest? >> reporter: lester, good evening. tonight in the steady rain, the exhausting and exhaustive search is far from scaling back. this is where most authorities say the biggest leads have come to. so tonight, they are in hot pursuit. the search team has grown to an army of 800, responding to 700 leads.

today, a neighborhood swarmed, the fbi on the ground, more tactical squads in the air. the police presence focused not far from the prison, scouring the woods for fugitives david sweat and richard matt. police moving in, keeping residents out. >> i own 50 acres up there. it's locked with a gate and they just wanted me to come down and unlock it. >> you see anything? >> no. they won't even let me up there. >> i don't think it will be unsolved. we'll get our men eventually. you know, i'm hoping that they are contained within this perimeter and it is them. everything's leading in that direction. >> reporter: it's not just the search but the scent helping investigators. >> now he's alerting. >> reporter: some of the most promising leads have come from canines. track and trail dogs can follow scents, even footprints, up to several days. but time is working against them, and now, so is the rain. >> the weather obviously plays a big part. the moisture makes a big difference. but the guys on the ground with the teams, the track and trail

teams, they're going to try and pick it up again this morning. >> reporter: the town of dannemora looks like a military state. schools still closed, heavily guarded checkpoints for miles. command posts scan 300 miles along the nearby canadian border. each night, infrared helicopters hover overhead, including the woods behind sierra armstrong's house. >> they said that they were, you know, fairly close. being that they don't necessarily know where they are, they could be in my backyard any night. >> reporter: a town under siege, two killers still on the run. while today's search wasn't the outcome they were looking for, they will continue to work around the clock. lester, we have been here since the very beginning. i can tell you during every search when they go door to door and through the woods, it is intense and heart pounding. officers say the next lead could be the big one they need. >> quite dramatic to watch. miguel almaguer, thanks. just one day after the feds admitted that a hack attack on millions of federal employees was worse than we were first

told, we're learning tonight of a possible second hack, this one compromising the most sensitive types of data on intelligence and military personnel. our justice correspondent pete williams joins us now from our washington newsroom. pete? >> reporter: lester, administration officials say that this second intrusion happened at roughly the same time as the breach of federal personnel records announced a week ago, believed to be from china. this other one got background details on people who hold or were applying for sensitive government positions, the kind requiring security clearances. officials say this other database includes such highly personal details as date and place of birth, social security number, work history, even names of parents and other relatives. although both these breaches were discovered in april, it's still not clear how many federal employee records were obtained. officials say they believe the chinese were most interested in using this data to try to get other government secrets, not to steal identities for financial reasons. lester. >> pete williams tonight. thank you. now to the role

reversal in washington that delivered a stinging defeat to president obama today on an issue near and dear to him. this time it came not from republicans but from dozens of members of his own party. for more, we turn to our capitol hill correspondent kelly o'donnell. hi, kelly. >> reporter: hi, lester. and imagine this. house democrats, including their leader, nancy pelosi, rejected president obama's top economic priority, trade, and they did it right after he made a rare trip to capitol hill. the president wants to get a package of trade proposals that he says will get more u.s. goods sold overseas. and republicans want that, too. but many democrats fear those proposals could eventually cost american jobs. to try to win them over, they added a federal program to retrain displaced workers, but that wasn't enough. democrats blocked it in order to stop the whole trade package. and tonight, the president is calling on congress to try again next week, but he will have to win

over more democrats. lester? >> kelly, thanks very much. this weekend will bring the most critical moment yet in these early days of hillary clinton's presidential campaign. she's holding a much-hyped event here in new york where she plans to get personal and show voters a side they may never have seen before. nbc's andrea mitchell has the details. >> reporter: she's been listening to small, carefully selected groups till now. tomorrow, hillary clinton's first campaign rally will get personal, focusing on her late mother, dorothy rodham, twice abandoned as a child by her parents, forced to make her way across country and work as a maid. >> my mom, who never got to go to college, could see her daughter go to college. >> reporter: clinton credits her mother for her passion and values, especially fighting for women and children, one reason she wants to be president. >> everyday americans and their families need a champion, a champion who will fight for them every single day. >> reporter: the backdrop, a new york park named for franklin roosevelt. challenging her from the left, senator bernie sanders, slamming clinton today for ducking tough issues. what about hillary clinton on the trade

issue? >> it is hard for me to understand how any candidate, hillary clinton or anybody else, cannot have a position on what is a major, major issue facing the american people. you're for it or against it, but you've got to have a position. >> reporter: clinton is dominating the democratic field, but recent polls show a big jump in the number of people who think she's not honest or trustworthy. since the controversies over her e-mails and donations to the family foundation. bill clinton will appear with her tomorrow, his first in this campaign. on cnn, he denied she did favors for his donors. >> i never saw her study a list of my contributors or -- and i had no idea who was doing business before the state department. >> mrs. clinton was the secretary of state for four years under president obama, and she has a record. and it's a record that she'll have to defend. >> reporter: clinton is counting on people caring more about her plans for the future than the past. andrea mitchell, nbc news, washington. >> let's bring in

chuck todd, nbc news political director and moderator of "meet the press." he joins us now. chuck, it's a big legacy weekend. you've got a big weekend not only for the clinton name but for the bush name. right? >> it is, and lester, what's interesting is both know they have the same problem and both are going to try to attempt to deal with that problem frankly, in similar ways, which is they have well-known last names, but both campaigns, the bush campaign and clinton campaign, believe folks don't know the real hillary or the real jeb. so, for instance, tomorrow, you're going to hear a lot about hillary rodham, the woman that was raised by dorothy rodham, her mother, as a way to explain why she wants to be president. the campaign believes that when you hear the story of dorothy rodham and you hear that it will provide sort of the backbone for what drives her on economic issues and drives her on family issues. jeb bush on monday is going to do the same thing. it's all about introducing jeb, the guy from florida, the governor of florida, not the brother of

george w. or the son of george h.w. it's tough for both of them, but it's going to be what they're going to attempt to do, lester. >> let me remind folks you'll have much more on this big political weekend and the clinton and bush campaigns coming up on "meet the press" this sunday. secretary of state john kerry was released from a boston hospital today, 12 days after breaking his leg in a bicycle accident in the french alps. walking with crutches, kerry thanked his medical team at mass general hospital. the break in his right thighbone was reset during surgery. kerry said he'll continue with physical therapy and even plans to get back on that bike. now to the controversy surrounding the naacp and raising difficult questions about race and identity. one of the group's leaders, accused of lying for years about her race. and it's her own parents outing her, claiming she's a white woman pretending to be black. nbc's ron allen reports. >> reporter: she's the head of the naacp in

spokane, an outspoken civil rights activist, part-time instructor of african-american studies at a local college. and rachel dolezal raised a lot of eyebrows with her answer to this question about race from a local reporter. >> is that your dad? >> yeah. that's -- that's my dad. >> this man right here's your father? right there? >> do you have a question about that? >> yes, ma'am. >> okay. >> i was wondering if your dad really is an african-american man. >> that's a very -- i mean, i don't know what you're implying. >> are you african-american? >> i don't understand the question of -- i did tell you that yes, that's my dad. and he wasn't able to come in january. >> are your parents, are they white? >> reporter: but now, dolezal's parents have come forward to say she's white. >> she wants to recreate reality. she wants to just invent it herself. >> reporter: they say their ancestry is czech, swedish, and

german, and that for years, their daughter has been misleading people. >> she's told herself, as well as she's told others, this erroneous identity of hers enough that by now, she may believe it more than she believes the truth. >> reporter: the parents said they've not spoken to their daughter in years. this unusual clash about race and identity has gone viral. amid the criticism, the naacp says it stands behind her and that racial identity is not a qualifying or disqualifying standard for naacp leadership. >> people claiming different ethnicities goes on all the time so much so that what we take as the standard is how people self-identify. >> reporter: still, the city is investigating whether she misrepresented her race on an application to serve on a citizen police commission. and as for dolezal -- >> would you identify yourself as an african-american? >> i actually don't like the term

african-american. i prefer black. >> reporter: no further comment from her today. ron allen, nbc news, new york. still ahead here tonight, imagine not being able to go out into the sun, having to live life like these kids do, in the shadows. but there is a place they can go where they don't have to miss out on summer. we'll take you there. and later, it's only a movie for now. meet the man behind the science of "jurassic world."

we're back with a summer ritual for countless families, sending their kids off to camp. and for most that means long days of fun in the sun without a care in the world. but for some children going to camp is an entirely different experience, one where the fun can't begin until the sun goes down. our national correspondent kate snow has the story. >> reporter: during the day, this summer camp in upstate new york doesn't look much like a camp. the kids are all hanging out inside. but at dusk, everything changes. >> get the ball! >> reporter: this is a camp for kids who can't be in the sunlight. so they play and swim at night. >> where's my goggles? >> reporter: there are more than a dozen rare diseases that force kids to avoid the sun. 10-year-old brady weeden has one known as epp, which affects about 500 people in the u.s. it's a genetic disorder that causes a painful reaction to any sun exposure. do you remember what it was like when you didn't know and you stayed out in the sun? >> yes. it was not pleasant, because i didn't know

it was happening. >> reporter: some patients say the reaction feels like being stabbed by knives. back home in bethesda, maryland, brady just finished fourth grade at his public school, but he stayed indoors during recess on sunny days. when he has to go outside, he wears a long-sleeved hoodie and runs from shadow to shadow. does it ever bug you that you have to sit in the shade? >> sometimes. i wish i could just be like them, my friends. >> throw it as hard as you can. >> if i throw as hard as i can, i'm going to hurt you. >> please don't. >> reporter: there is no cure for epp. but brady's mom, kristen, has been advocating in washington for an experimental treatment that might offer some relief. >> it's his hope. i let him have that hope, that someday, he will get to lead a normal life without this struggle. >> reporter: implanted under the skin, the drug increases pigmentation for two months. >> what it does is give a layer, a protective layer. >> reporter: kind of

like a coat of armor. >> that's a great way to look at it. >> reporter: the drug is available in europe but not approved in the u.s. so for now, brady will spend the summer looking for shadows, except for that one week in july, when he'll return to camp sundown. >> it feels like i'm a normal person. >> reporter: a place where he's not alone in the dark. kate snow, nbc news, new york. >> you can watch more about brady's story and other kids like him this sunday night on "dateline." we're back in a moment here with a crazy takeoff. should a passenger plane be able to do that?

millions of folks are keeping an eye on potentially severe weather tonight from texas to new york. this is how it looked this afternoon in western indiana after one small town got pounded by hail, wind, and heavy rain. lots of trees were down, and at least a foot of water was

reported downtown where the fire station was flooded. three, two, one. zero. all engines armed. we have a lift-off. lift-off on apollo 11. >> his was the voice millions heard in one of mankind's finest moments. now jack king, known as the voice of "apollo," has died. king will forever be remembered for counting down that first moon mission along with so many other space shots. starting as a reporter for the associated press, he joined nasa in 1960 as the agency's spokesman. jack king was 84 years old. and a very impressive flight for a modern aircraft. boeing released this video of one of its new 787-9 dreamliners, making an almost vertical takeoff in washington state, a practice run for next week's paris air show. painted in the colors of vietnam airlines, boeing's customer, the plane showed off some of its moves, the kind of maneuvers you rarely see by a commercial aircraft and certainly won't see with paying passengers on board. am i the only one who reached for their seatbelts for that one? when we come back, how much is science

fiction and how much is science fact in this weekend's big blockbuster, "jurassic world."

next at 6: a south bay home invasion that made national news. ===take vo=== now -- a stunning twist. the person police are calling... "the mastermind" of the crime.. ===janelle/take vo=== plus, blobs on the beach. why these creatures are washing up on bay area shores. ===next close=== next. it's been 22 years since "jurassic park"

thrilled us and terrified us by bringing dinosaurs back to life. this weekend, audiences are lining up for the highly anticipated sequel, "jurassic world." so why do dinos still hold so much fascination for us 65 million years after they went extinct? our joe friar put that question to experts, both young and old. >> reporter: unlike the movie "jurassic world" -- >> is that a t-rex right there? >> reporter: -- there is no pg-13 rating for the dinosaur exhibit at l.a.'s natural history museum. >> that's the nose right next to the big teeth. >> reporter: all ages are welcome here. >> crocodilians are crocodiles that ate birds. >> reporter: take 5-year-old homer hume. dinosaur names were among the first words he ever learned. >> i know velociraptor. >> velociraptor. >> i know pachycephalosaurus.

>> pachycephalosaurus. >> reporter: now comes the latest chapter in the jurassic series, a universal film. in the original "jurassic park," the role of bad guy was played by tyrannosaurus rex. but this time around in "jurassic world," a new villain has come to town. >> what is happening? >> reporter: this is indominus rex. the genetically modified predator is a scary stew of features from different dinosaurs. >> it is the most interesting dinosaur that never existed. that's a fact. >> reporter: paleontologist jack horner helped create the fictitious monster. in fact, he has been an adviser to filmmakers on all four of the jurassic movies, typically dealing with fact, be not fiction. >> my job really is to sort of make sure the science is as accurate as it can be. >> reporter: horner admits the dino depictions are not always perfect, but feels this latest movie is the most accurate yet. >> i'm at the stegosaurus. >> reporter: while homer might be too young to see the film, he's proof you're never too young to immerse yourself in a jurassic world.

joe friar, nbc news, los angeles. that will do it for us on a friday night. i'm lester holt. for all of us at nbc news, thank you for watching. and good night. combination, the heat -- accelerating the drought. tonight, . it's a dangerous combination. the heat accelerating our drought. tonight the bay area is being hit by both. good evening, thanks for being with us on this friday. i'm raj mathai. i'm janelle wang in for jessica aguirre. it's been a sweltering day, some places topping above 100 degrees. in foggy san francisco, you can see the clouds moved out and things heated up. tonight we talk about the coverage of the heat. jodi hernandez is standing by in livermore, one of the hottest spots today but first chief

meteorologist jeff ranieri talks about the weather and how long it will stick around. >> high pressure across the west coast is blocking any kind of colder air and storm systems that could move our way this time of the year the second component that's producing the heat is some very hot air pushing in from the desert. it's more like july and august type of air moving in at the current moment. as we get a look at the current temperatures, we're averaging cooler weather at least from the daytime highs, 77 in the north bay, san francisco 71 and the south bay at 81. but the one spot that is having a hard time dropping right now is the east bay with an average of 94 degrees. you'll be able to see here where it's still warm. lafayette 92. orinda 87. danville 95 degrees. 100 in pleasanton. livermore at a hot 94. here's the thing. we just learned we broke a record in livermore with the official high at 101 degrees. that is a 66-year-old record as we
