Headquarters in new york this is nbc nightly news with brian williams. Good evening. The feds say they were onto it early, but tonight theyve announced theyve stopped a plan apparently inspired by isis to attack the u. S. Capitol and those inside it. Its an example, they say, of the kind of lone wolf attack that can get its inspiration from people and movements overseas. We begin tonight with late details from our justice correspondent Pete Williams in our d. C. Newsroom. Pete good evening. Reporter brian, good evening. U. S. Officials say this is precisely what they worry about most someone in the u. S. Becoming inspired by terrorist propaganda to carry out attacks here at home. The fbi says 20yearold Christopher Lee cornell of Green Township ohio wanted to set off pipe bombs at the u. S. Capitol and shoot people as they fled. Investigators say he came to their attention last august when he posted proisis messages on twitter using an alias, raheel mahrus ubaydah. Court documents say he discussed his plans with a man he thought was sympathetic but who turned out to be working undercover for the fbi. According to investigators cornell said the former al qaeda figure awlaki and others had expressed the view this kind of jihad was the right thing to do. Cornell was arrested earlier today after he bought two assaulttype rifles like this and 600 rounds of ammunition. Spent at least enough time with these particular officers to know that i was in good hands. They knew what they were doing and they exuded a lot of confidence. Reporter federal officials insist there was never any danger because the man was under close surveillance for months. He didnt build pipe bombs and didnt even buy the components for them. Pete williams starting us off from our washington newsroom. Thanks. Its taken a full week but one of the most likely suspects in the terrorist attack in paris has finally claimed responsibility for it. Al qaeda in yemen says it was behind the bloody assault on the offices of that satirical newspaper called Charlie Hebdo. But rather than being silenced the paper put out a new edition on the stands today. Clearly its bigger than ever. We have two reports on all of it tonight. We want to begin with Nbcs Richard Engel in istanbul. Richard, good evening. Reporter good evening, brian. The last year isis has been dominating headlines overshadowing al qaeda. Something about dangerous rivalry is emerging a game of oneupsmanship between the two groups. Al qaeda is launching a comeback. The attack on Charlie Hebdo last week was al qaedas most high profile operation in years. And today they bragged about it. In a video al qaeda in yemen claimed it targeted the magazine for insulting the Prophet Muhammad even laying out the chain of command behind the attack. Ordered by alzwarhi osama bin ladens successor. Anwar alawlaki before he was killed in 2007 and carried out by cherif and said kouachi. Reports suggest the brothers got their automatic weapons from this man, Amedy Coulibaly who has now turned himself in to police. Coulibaly also bought the two machine guns he used to attack the kosher market. New images from security cameras show him inside the market wearing a bulletproof vest. His hostages huddled in fear. Some of them order today disable the security cameras. [ gunfire ] reporter coulibaly killed four of the hostages before police stormed the market and killed him. His suspected accomplice hayat boumeddiene, left paris before the attacks and came here to istanbul before disappearing into syria. The investigation is yielding new suspects daily, but the real focus now is preventing the next attack. Richard engel, nbc news istanbul. Reporter this is bill neely in paris where people waited hours to buy the magazine terrorists tried to kill off. It normally sells 50,000 it sold out fast 3 million copies. Many bought it to defy the terrorism. I wanted to buy this one to reporter 3 million copies sold, another 2 million ordered in numerous languages. The cartoonists say this issue of the magazine depicting on its front page a tearful Prophet Muhammad is a triumph for free speech. In muslim areas of paris they disagree. They say showing the Prophet Muhammad is provocative. More provocation. Why you talking about my prophet . Why you talking about this god . I think it will bring a civil war. Reporter you think a civil war is possible . Civil war is coming yes. Reporter police have now charged this famous muslim comedian who identified with one of the killers with advocating terrorism. More than 50 more muslims have been arrested for defending terrorism, mostly on social media. The killings carried out by islamic extremists have resulted in more than 50 revenge attacks on muslims, mostly minor. The french president was talking tough today on an Aircraft Carrier heading to the middle east on air strikes against islamic militants. Striking militants at home without alienating his muslim fellow countrymen is now his biggest challenge. Today, a week after the massacre this magazine became the biggest oneday sellout in french publishing history. Tomorrow secretary of state kerry arrives here to discuss the aftermath of the massacre and how to stop another one. Brian. Bill neely in paris, Richard Engel before that. Our team remains on this story. Gentlemen, thank you both. Word out of washington tonight, a major shakeup on the way in the u. S. Secret service. The agency is removing four highlevel officials from their posts after a series of embarrassing incidents and dangerous lapses. Among the men and women charged with protecting the highest office in the land. We get our report tonight from our White House Correspondent kristen welker. Reporter it is a Major Overhaul for an agency in crisis. Four assistant directors are being tossed out of their current posts and reassigned. Acting director joe clancy saying in a statement, change is necessary to gain a fresh perspective on how we conduct business. Those being replaced come from every part of the Department Paul morsi, investigation,s jane murphy governmental affairs, and mark copanzzi. In an interview with brian last month clancy signalled big changes. We have zero tolerance with misconduct. Weve got training in place. Weve got an integrity board in place. Reporter the agency is trying to come back from a series of security lapses among them agents getting caught with prostitutes during an official president ial trip to colombia in 2012. A fencejumper making it all the way inside the white house late last year. This may be a really critical moment for members of the rank and file who have been clambering for a change in leadership. Reporter brian, each of the four reassigned employees has more than 30 years of service. No word on their new assignments. All of this comes after an independent report described a culture of low morale and poor leadership at the secret service. Brian. Kristen welker on the white house north lawn tonight. Kristen, thanks. Now a tense day in space for the astronauts onboard the International Space station and for Mission Control here on the ground at nasa. The crew two americans, one italian, three russians were forced to take refuge and safety in the russian side of the space station as onboard alarms warned of a possible toxic leak onboard in the section normally occupied by the american astronauts. We get details tonight from nbcs tom costello. Reporter floating 250 miles above the earth, space station astronauts spent much of the day wearing emergency oxygen masks testing the air after Early Morning alarm bells warned of a possible ammonia leak in the cooling system on the american side. The order from Mission Control, don the masks, get to the russian side and close the hatch. Bottom line is we get all the experts coming in now, everybodys poring over the data we have the smart folks taking a look at it. Reporter an ammonia, toxic leak rapid decompression, fire or smoke event are among the most serious emergencies on the space station. Any one could force the crew to abandon the station in a russian capsule. These kinds of emergencies start with protecting the crew then trying to deal with the issue. And then if in the end we cant deal with the issue, some of them can result in evacuating the station. Reporter the six crew members were supposed to spend the day unloading a resupply spaceship launched by spacex. But as they hunkered down in the russian section, Mission Control became more convinced it may have been a false alarm caused by a bad computer card. There is no data at the moment suggesting that there was in fact a real ammonia leak. Reporter veteran astronaut scott kelly is preparing to spend a year on the station with cosmonauts. Especially with the crew members, the cosmonauts were great friends. We have to work together. We have to rely on each other literally for our own lives. Reporter after running air quality tests all day, Mission Control gave the allclear to the as tro naughts just after 3 00 p. M. Tonight it is all resumed normal operations. Tom costello in the safety of washington, d. C. Tonight. Tom, thanks. Over the better part of these last three weeks we have witnessed the test of human skill and endurance really unlike any other on a mountain unlike any other. And tonight we have witnessed the culmination of all of it. Two men have completed whats been roundly described as the most difficult free climb in the world. Nbcs Miguel Almaguer is right there at the very top of el capitan in yosemite forest tonight. Reporter brian, good evening. This is the moment that has been so many years in the making. We were here live when kevin when Tommy Caldwell and Kevin Jorgensen came up the mountain were greeted after climbing 3,000 feet up el capitan. They gave their wives hugs they popped champagne. They are still hugging family at this moment. My colleague Hallie Jackson has been following their journey for the last several weeks. Reporter its a moment seven years in the making but 19 days ago no one knew if it would happen. After Tommy Caldwell and kevin jorg ensen started the hardest free climb in the world. Their shredded fingertips grabbing granite flakes as thin as dimes. Inching up a section at a time, one slip means starting over. Ropes there only to catch them not to help them. Between climbs life suspended on a wall each night sleeping thousands of feet above the valley floor. Think about everything you done in the last two and a half weeks, every time you went to the store, every time you had dinner they were on that cliff. Reporter as momentum builds the meadow below fills with onlookers eager to learn more about the two friends, jergensens childhood climbing competitions caldwells escape after being kidnapped and a freak accident that left him with nine fingers in a sport where sometimes even ten arent enough. All of these hardships hes been through all have led up to this moment for him to be able to say this looks impossible but im going to try it anyway. Reporter from a distance the climbers families feel each triumph and tension. Oh your heart just drops. You know how bad he wants to do it. Talk about tenacious. Reporter jerg ensen slipped again and again until finally he didnt. I couldnt be happier. Reporter thats when they seem unstoppable. This is a view that ill always remember. Reporter two friends climbing into history proving the impossible may not be. The folks up top could probably hear the cheers of joy from the meadow down below 3,000 feet beneath them. And while there is a sense of elation, its also bittersweet. As tommy cold wells mother told me this is a realization of a dream but also the end of one. Hallie jackson at the base before that Miguel Almaguer at the summit miguel might have gotten the better part of this deal. Still ahead tonight, well go back to Miguel Almaguer at the summit and show you how we managed to beat the climbers to the top in just one day. Heres a broad hint there is a back way.

We get our report tonight from our chief medical expert dr. Nancy snyderman. Reporter take a person infected with measles, combined with thousands of disneyland tourists and you have the recipe for the worst Measles Outbreak in california in years. Doctors are scrambling to get ahead of this. Worst situation because lots of people lots of children. Reporter its a serious yet preventable disease that has now spread beyond california with reports of 26 ill people in utah colorado and washington state. It can lead to blindness. It can lead to encephalitis. Reporter symptoms are dry cough, runny nose red, watery eyes and a rash. People can spread measles up to four days even before the rash appears. A significant number of people in this outbreak were not vaccinated either opting out or too young to get a shot. In long beach, california, one infected patient went to multiple stores. This gym posted a sign about the Measles Outbreak prompting questions from customers. Do we need to get in and get another booster . Do we need to worry about it because weve already had the measles. So we called our doctor first. A child gets the first dose of vaccine at 12 to 13 months of age and the second one at 4 to 6 years and right now even adults are considered candidates for getting a booster. This brian, i think is going to take days if not weeks to figure out the entire area. Nancy, thank you as always.

It took them 19 days by hand. Our team made it up to the top in a single day. They made the journey the way a lot of hikers and tourists do which is they went the back way. Which is not without its challenges we should hasten to add. We get our report tonight from nbcs Miguel Almaguer. Reporter our hike to the summit began at 5 00 a. M. Along a treacherous trail through the backcountry. Eight miles and ten hours to the top of el capitan. Its pretty rocky, pretty steep. You can see the terrain were dealing with here. Its also quite breathtaking. Theres the falls right there. You can see it iced over. Shot at the valley. And our crew behind us whos working their way up this hill. The yosemites trail is popular for thousands of hikers each year the view of the waterfall north americas highest at roughly 2,400 feet, is spectacular. Were accompanied by a guide, but once here most hikers turn back. It looks intimidating. Thats the top of the wall were trying to reach 3,000 feet up. Weve come a long way from this valley floor. Its cold up here but thats good for hiking weather. Weve reached a mile marker here. Weve got about four and a half miles to go. Still a lot of distance to cover. A good stretch of the trail is actually covered in snow. Thats where weve reached slowed us down quite a bit. Its really slippery. Its like ice literally. There are a hundred trails up to el capitan. It was first summited in 1958. For those who make it to the top the reward is pure beauty the view of a lifetime. For those who reach the summit whether it was up that shear granite wall or around the back trails like us theres pure joy and celebration going on right now atop here.
