"nightly news" begins now.

good evening. while americans are still absorbing the blunt force of this latest mass shooting, tonight a lot of the details of what we thought we knew about the gun massacre at the washington, d.c. navy yard have changed. the new director of the fbi briefed a group of journalists today including our justice correspondent pete williams and he laid out a version of events that differs from what we were first told and first reported. pete is with us tonight from our d.c. newsroom to start us off. hey, pete. good evening. >> reporter: brian, good evening. the fbi director james comey says the surveillance video and physical evidence show that nearly half an hour passed from the time the shooting started until the police teams found aaron alexis and fired back. the fbi director says alexis began firing his shotgun shortly after 8:00 a.m. in a fourth floor hallway. comey says alexis was wandering

the halls hunting for people to shoot with no signs of targeting anyone in particular. washington, d.c. police say the first call for help didn't come until 8:21 with units then dispatched. >> we had a report on the fourth floor, a male with a shotgun, multiple shots fired. multiple people down. >> reporter: after killing an entrance guard and taking his handgun, officials say, alexis continued shooting in upper hallways. comey said he fired the shotgun until running out of shells he carried in a cargo pants pocket, then switched to the handgun. there is no evidence, the fbi says, that alexis fired from the upper floors down into the atrium below. but it wasn't until half an hour after the shooting started, the fbi says, that the first officers to enter the building found him and had him in their sights. >> they could hear gunfire. because of the size of the building, difficult to pin down where the gunfire was coming from. >> reporter: after walking past the dead and injured, two

officers finally located alexis inside an office, hidden among a maze of cubicles. >> there was carnage everywhere in this building. absolute carnage. when officers have to go past people who are asking for help because they still have yet to neutralize the threat that weighs heavy on your mind. >> reporter: officials praised the prompt action of first responders but a navy police union says its force was understaffed preventing quicker action. members of a u.s. capital police tactical team say they were preparing to enter the navy yard to help, but were ordered back by a superior. >> i asked the capital police board to do an independent fact review of the allegations to find out exactly what happened. >> reporter: also tonight michael isikoff reports the navy security clearance check for alexis was done by the same private firm who did the check for edward snowden to join the nsa where he then stole and leaked hundreds of classified documents. brian? >> pete williams with the latest

from washington tonight. pete, thanks. the new head of the catholic church, pope francis, has given an interview that contains some comments that seem to a lot of people today to skip the catholic church ahead in time many times over. it's been clear from the start he doesn't act like any of his predecessors and this is now confirmation he sure doesn't talk like any previous pope. for starters he said in the first extended published interview that the church has become, quote, obsessed with preaching about gays and abortion and contraception. he says people want pastors, not clergy acting like bureaucrats or government officials. it goes on from there. we get our report tonight from nbc's anne thompson. [ cheers and applause ] >> reporter: in his short papacy pope francis has preached loudest with gestures, drawing tens of thousands to his weekly audience in the vatican, and millions in rio, his first overseas trip. today it's the pope's words making headlines as he spells

out his vision of the catholic church in a remarkably frank interview published in the jesuit magazine "america. we cannot insist only on issues related to abortion, gay marriage and the use of contraceptive methods. he said we have to find a new balance. otherwise even the moral edifice of the church is likely to fall like a house of cards. >> it's certainly a change in tone. and it is certainly a change in approach. we have never had a pope talk to the world like this. it is a remarkable thing. >> reporter: this pope is focused on peace, leading a prayer vigil for syria earlier this month, highlighting the plight of immigrants. now reaching out to lapsed catholics who if they were a denomination would be the second largest religious group in this country, behind practicing catholics. the pope urging clergy to seek out those who have left and listen to their reasons why. this interview followed his

impromptu press conference in july when he said, who am i to judge when asked about a gay priest. now speaking about all gays, the pope says when god looks at a gay person does he endorse the existence of this person with love or reject and condemn this person? we must always consider the person. >> i think that there are a lot of catholics who still go but feel excluded. and now this message that he's given has given an opportunity for them to feel more welcome. >> reporter: despite the new openness, few expect radical change in the 2,000-year-old institution. >> this is certainly not saying there is going to be a historic reversal in the church position or in church teaching. it is just an emphasis that a lot of american catholics are welcoming. >> reporter: the interview wasn't all church business. the peep revealed he watched all the classic italian movies as a child and his favorite is about a young woman sold to a street performer. the pope is an opera buff.

his favorite writers include dostoevsky. and his favorite composer is mozart. but most of all he wants his church to be a church for all, not a chapel for a small few. >> that's a remarkable thing. anne thompson, thanks. there is more news tonight from tehran after ann curry's exclusive interview with the new president of iran. she is the first western journalist to have access to hassan rouhani. the reaction continues today to what he said, especially concerning what he said about nuclear weapons. in a moment some of the reaction. first tonight ann has more from tehran on what happens when he comes to the u.s. next week. ann, good evening. >> reporter: that's right, brian. good evening to you. the strong statements from iran's new president that he would never build a nuclear weapon and has full authority to negotiate a deal has sparked growing anticipation, especially here in iran about what might happen when he goes before the united nations next week.

are you willing to meet with president obama in new york at the united nations? >> translator: i do not have any plan to meet president obama in our agenda. >> reporter: would you be against meeting with president obama in the near future, mr. president? >> translator: well, anything is possible in the world of politics. it depends on the necessary conditions. >> reporter: mr. president, president obama has revealed that you and he have exchanged letters. could you please describe the tone of those letters? >> translator: he congratulated my election and some issues of his interest raised in the letter. i responded to that letter. i thanked him. i expressed iran's viewpoint. from my point of view the tone of the letter was positive and constructive. >> reporter: do you see it as a foundation?

>> translator: it could be subtle and tiny steps for a very important future. >> reporter: president rouhani was careful when asked about iran's recent past. much of what americans think about iran is influenced by your predecessor and some statements he has made. let me ask you. president ahmadinejad said the holocaust is a myth. do you agree? >> translator: i'm not a historian. i'm a politician. what is important for us is that the countries of the region and the people of the world grow closer to each other and that they are able to prevent aggression and injustice. >> reporter: if i might ask you one more time, do you want to decry those statements? >> translator: we are not seeking and looking for war with any nation. we are seeking peace and stability among all nations in the region. >> reporter: president rouhani

also went so far to say if americans have political will, resolving the political issue could be simple and settled in a, quote, short period of time. brian? >> ann curry from tehran again tonight. thanks. there is much more of ann's reporting including her journey within iran. we have put it on the website tonight, nbcnightlynews.com. now to that reaction from washington and around the world. our chief foreign affairs correspondent andrea mitchell at her post at the state department again tonight. good evening. >> reporter: good evening, brian. based in part on those comments to ann curry, u.s. officials are eager to test the new president of iran's seriousness, possibly as early as next week in new york when both leaders will be at the united nations. president obama and rouhani have already broken the ice with a warm exchange of letters mr. obama initiated. as headlines from around the world noted his comments to ann curry disavowing a nuclear threat. the administration acknowledged a clear change in tone from

tehran. is it a positive sign coming in this interview? >> the comments have been very positive, but everything needs to be put to the test. we'll see where we go and at the right moment i think the white house and state department will make it clear where we are heading. >> reporter: though iran usually blocks iranians from twitter now rouhani is tweeting pictures of him with ann, quotations from their interview, even re tweeting a picture of a prominent human rights lawyer his government released along with ten political prisoners wednesday. a key player in syria, rowhani's foreign mister zarif who returned to the u.n. today where he's known well from years as iran's u.n. ambassador. while most of the world reacted positively, israel remains skeptical. >> the iranian president used a lot of sugar-coated words. he did so deliberately in order to deceive. we don't need words from the iranians. we need actions. we need them to stop their

nuclear program. >> reporter: british officials say they are cautiously optimistic that the comments could lead to something serious. france's president hollande will meet with rouhani next week in new york. that raises the stakes for whatever president obama decides to do. brian? andrea mitchell at the state department tonight. thanks. now to a number in the news tonight that's become a sad part of american life. one in seven americans relies on food stamps. there is an intense fight under way over how much taxpayer money should keep going to this longstanding part of what's traditionally been called the safety net. tonight the house of representatives approved deep cuts to the food stamp program though democrats vow to block them. as a part of our series of reports on poverty called "in plain sight," we get the story tonight from john yang in chicago. >> reporter: every thursday audrey goes to a church food pantry on chicago's south side to restock her pantry at home. >> how long will this last?
