sign her up for the spelling bee, hechilping her study in 20-minute increments. we talked to her. when you're not spelling what do you like to do? >> i like to play hide-and-seek or something like that. >> reporter: but don't hide because you have a lot of spelling to do. >> but there's times to play and times to not play. maybe in times to not play i can spell and the times to play i can go and play hide-and-seek. t -- >> reporter: and for edith, sometimes there's a way to do both. >> a-s -- tapas. >> reporter: cbs news, maryland. that is the overnight news for this thursday. for some of you, the news continues. for others, check back a little later for the morning news and cbs this morning. from the broadcast center in new york city, i'm jeff glor.

this is the "cbs overnight news." welcome to the overnight news. i'm michelle miller. a turning point in the investigation of russian influence on the presidential election could come next week when fired fbi director james comey testifies on capitol hill. comey is expected to confirm reports that president trump asked for his loyalty and pressured him to close the justice department probe. jeff pegues reports. >> reporter: sources tell cbs news that special counsel robert mueller has given his blessing for former fbi director james comey to testify before congress. comey is expected to discuss memos he wrote about meetings with president trump, including one in which comey says the president asked him to drop his

investigation of fired national security adviser michael flynn. according to the memo, the president said of the private meeting, i hope you can see your way clear to letting this go. he is a good guy. flynn is the subject in the russia investigation and today the president tweeted again that the probe was a witch-hunt. he also defended one of his former advisers, carter page, writing democrats have excoriated him. in an interview today, page denied any wrongdoing. >> i think it's going to be such an open and shut case. >> reporter: well before he joined the trump campaign, page was named as male-1 in a fbi case that led to the 2015 arrest of russian spies in new york. court papers allege the russians tried to recruit page. there are now questions about whether he was properly vetted by the trump campaign. >> people knew me very well, going back many years, so, not directly within the campaign, but people i knew.

>> reporter: democrat eric swalwell is on the house intelligence committee. >> carter page is certainly an individual who we would like to hear from, as we would like to hear from any individuals who had contact with the russians during the time of the interference campaign. pentagon officials and military contractors are still t of a new antimissile system and they're planning another test for next year. the military launched a missile carrying a dummy warhead from an island in the pacific. it then launched an intercepter missile from a base in california. and the dummy warhead was destroyed. the test comes amid north korea's increasing threats. david martin has more. >> reporter: since north korea has said it is finishing work on an intercontinental ballistic missile, this was important that the united states has the capability at least under test conditions to shoot down an incoming icbm. lifting off from a tiny island in the middle of the pacific

ocean, the missile was designed to fly at the trajectory and speed that north korea may be able to launch three years from now. vice admiral james searing spoke to reporters from his operations center in colorado. >> this is exactly the scenario we would expect to occur during an actual operational engagement. >> reporter: the plume of the missile was detected by a satellite, which triggered the launch of an interceptor missile from california. the interceptor carried a 5-foot-long kill vehicle which maneuvered into the path of the incoming warhead. this is what it looked like to infrared cameras. >> we have information it was a complete obliteration, a direct hit. >> reporter: this giant sea-based radar helped track it as it raced toward space at four miles per sdechblgt the radar might not have time to get into

position. it's hard to think of the united states in an arms race with an impoverished country like north korea, but that is essentially what's happening. u.s. missile defenses racing to keep ahead of north korea nuclear missiles. if north korea ever does attack the united states, the missile will be tracked by radar in the arctic. the u.s. maintains an air base in green land. jeff glor paid a visit. >> reporter: the air base 750 miles inside the arctic circle is not easy to reach or maintain. but the u.s. did just complete a significant upgrade f and missile defense there. one of several early warning systems being improved worldwide. with developments in north korea and russia coming daily ey, it' not just on top of the world but on top of many military minds. on one of the most isolated misses of land on earth, a base with no roads leading in, an island covered more than 80% in

ice. the air force needs to stay constantly connected to the sky. >> 900 miles from the north pole and five hours flying time away from russia's industrial hub is the american airfield. >> reporter: at the height of the cold war, the air base was a site of symbolism. today we were invited on base by colonel christopher eagan who took control just last year. >> we have a unique access this far north that the department of defense does not have anywhere else. >> reporter: in training sessions, air men learn to surveil the sky, always on alert fort worst-case scenario, a missile fired from's yeah. heat signals from launches are typically first picked up by satellites in space. but radar on the ground remains essential to track after that. and no u.s. base sits farther

north than thule. the location of the 12th space warning squadron. their $20 billion radar just got a $40 million software upgrade. one of six early warning systems like this around the world being improved. more than 3500 antennas here can see 3,000 miles into space. why is this so significant? >> because as the technology changes, it becomes more accurate and with the proliferation we're seeing across the globe there's more interest in being able to take measures against them. with the evolution of time we've gone away from aircraft to radar. the mission may have changed. but the access to location remains the same. >> reporter: thule is now home to only 200 military personnel. they come for a year at a time, climate and conditions are considered too harsh beyond that. >> i got here last june. >> reporter: michael fer ar is

the base chaplain. >> it's an a mazing mission, who else can say you went to the top of the world. you don't hear birds. there's no trees. >> reporter: never mind not seeing daylight for four months. >> i tell you what, when people said not seeing the sun for 100 days was hard, as a chaplain, i was thinking, we can get through anything, but it was hard. >> reporter: those willing to make this trip often cite the brutal beauty of greenland. they're also keenly aware of the mission. when you see how much attention folks are paying to the arctic circle now, especially from a military perspective, it has to put you on edge. >> the increased interest on the political side of the house is interesting. but we've invested for the last 60 years in the capabilities here. when our most important resources are people and they're that trained and they want to be here, the rest goes away. >> reporter: the sun won't set again in thule until august.

. when former president barack obama loosened travel restrictions to cuba, a lot of people expected a flood of tourists. well, that hasn't happened. cuba is still essentially a third world country. hotels and restaurants are overcrowded and expensive. most credit cards don't work. cell phone and wi-fi service is spotty, and now a third airline has decided to ground its flights to cuba. kris van cleave has the story from havana. >> reporter: for americans to come here, they have to meet specific visa requirements, even though those have been loosened. it is confusing. just last week, 55 u.s. senators co-sponsored a bill that would lift the restrictions all together. and that is something the airlines would like a whole lot. when the first u.s. commercial

flight in more than 50 years touched down in santa clara, cuba last august, many here expected a u.s.-driven chick boom to follow. and while the number of americans did surge 74% last year to nearly 300,000, many expected more. how has it been so far? >> amazing. >> fantastic. >> it's been a wonderful experience, yeah. >> reporter: bridget kelly from washington, d.c. met her friends from l.a. in havana. >> i thought there would be more americans. ♪ >> reporter: it's a bit of a cuba contradiction. while hotels are -- did you expect to see more americans than you've seen? >> yeah, i was expect, yeah. because it's so easy. >> reporter: tonight spirit will be the third u.s. airline to drop service to the island. spirit says there are too many

factors that prevent people from traveling easily from the u.s. to cuba and costs of serving havana continue to outweigh the demand. some analysts expect americans visiting cuba to hit2 million annually by 2025. but a survey this month said only2% were likely to plan a trip in the next six months. did the gold rush just not happen? or just not as fast as people thought. >> i think not as fast as people thought. >> reporter: colin organizes tours in cuba. >> the luxury's in the people, the art, the music, the culture. >> reporter: they believe americans will see the appeal in time. but american airlines cut service by 25% as it reduced flights to several cities while still opening a ticket office in havana to katder to cubans. >> the predictions say that there's going to be a tremendous growth. >> reporter: giselle cortez is

jetblue's director of international airports. >> i can't speak for the competitors, but jetblue remains committed to this market for the long haul. >> reporter: the tourist infrastructure is lacking. cell phone service is spotty, so is wi-fi. and most americans can't use their credit cards while they're here. the early winner appears to be cruise ships. they bring all the infrastructure they need. they are reviewing loosened travel restrictions so this all could change again. north of cuba, the everglades is the largest wet land habitat in the united states, covering 2,000 square miles of south florida. but the everglades has been under assault for decades from residential development, water die version and pesticide run off. now a massive project is one step closer to putting more freshwater into the ecosystem. manuel bamore cuss reports.

>> reporter: these massive savannas of saw grass. a bird's-eye view is the only way to truly appreciate the size and scope. some of the rare bird species that call the everglades home are sounding the alarm for the health of america's unique wetlands. the strangely beautiful rosie spoonbill has raised its young in the everybody glades fglades if not thousands of years. this is miles north of their traditional nesting area. they need small freshwater pools to feed, and those are disappearing from the glades. how disturbing a trend is it? >> it's very scary. you know, we see a lot of saltwater intrusion, which is also something that is very it changes the habitat, makes it less productive. >> reporter: jerry says it's more than just birds.

the entire ecosystem is out of balance. what have we done to the everglades? >> biggest thing we've done is drained it. >> reporter: for? >> for our purposes. >> reporter: development? >> development, agriculture. this was the big land boom. there were people who look at that swamp and said what a waste of land. fertile soil, let's drain it. >> reporter: freshwater from the kissimmee river used to flow south. during the rainy season the water would filter through the everglades all the way to florida bay. but development has blocked much of that natural flow. this is what one part of the glade the looked like in 1970, and this is just 30 years later. we've already lost, what, 50% of the everglades? >> that's about right. yes. >> reporter: is the rest of it salvageable? >> yes. the only way to do that is to restore that flow. >> reporter: the die version and disruption of that water are largely responsible for toxic algae blooms in recent years. now nearly 20 years after a

major everglades restoration plan was first agreed upon, the florida senate this month finally approved a $1.5 billion reservoir to collect and send some of the overflow back through the everglades. >> this allows us to restore somewhat of that to provide freshwater to everglades park and florida bay. >> reporter: steve is a wetlands ecologist. it's giving back some of the war water that made the everglades the everglades. >> absolutely. >> reporter: but another danger lurks, sea level rise. more saltwater is seeping in. left unchecked it could one day taint the drinking supply for 8 million people in south florida. >> in is a marsh that has been exposed to saltwater intrusion. >> reporter: dr. tiffany walked us out to one of her projects to show us how saltwater is already

damaging salt grass plants. >> it was three times higher than what we thought we would experience here. >> reporter: he sashe says thats reintroduction of saltwater all more important. and while many think the everglades are beyond the tipping point she remains hopeful. >> i'd like to say we got ourselves into this mess, we can figure out how to get ourselves out of it. >> reporter: to be sure, the reservoir project still has a long way to go. congress must approve the federal share of funding and it must still be built. out of 68 projects, only six are currently under construction. will be right back.ernight news- back. ♪ lysol max cover kills 99.9% of bacteria, even on soft surfaces. one more way you've got what it takes to protect.

for more than a year now, we've been following the story of adrian balancen jer and corey richards, a pair of mountain climbing adventurers who have been trying to snapchat their way to the top of mt. everest. the trick is, they were attempting the feat without the use of cananed oxygen. they made it to the top of the world. >> reporter: this week both adrian and corey reached the peak. but it was adrian who accomplished the ultimate goal of making it without extra oxygen. the highs and lows of it all shared with the world on social media. >> here we are. one year later. >> you did it! >> reporter: their body the pushed to the limit, cory and

adrian spent less than 15 minutes on top of mt. everest, taking in a view few others have seen. >> ladies and gentlemen, not only is my phone not dead, but that is adrian balancen jer with no oxygen. >> reporter: only adrienne did it without supplemental oxygen. high altitude sickness forced cory to turn back. >> the summit is just through the clouds. up above us. >> reporter: on his way down, cory met a group of climbers who supplied him with supplemental oxygen. the oxygen gave cory the energy to reach the summit first, from there he cheered on his friend as he made the final push. >> 3,995 feet right now. i've never seen anybody work so hard for anything in my life. my brother, we leave the summit behind. >> reporter: in 37 days, adrian logged nearly 140 miles while

acclimating to the high altitude. he consumed 22,000 calories on a diet that allowed him to consume air at roughly 8% oxygen. adrian reflected on the experience. >> i feel super emotional. i cried so hard yesterday on the summit. in the last ten meters to the summit. i would never want to climb everest without oxygen again, and i am so proud and happy. >> reporter: he said cory's support gave him the energy he needed. >> it was just so amazing to be up there with cor. we did it together. as it was planned, so. a fitting ending. >> reporter: and that's the overnight news for this thursday. for some of you the news continues. for others we hope you will check back with the morning news a and cbs this morning.
