important thing, finding strength in numbers to celebrate their faith. >> wherever we are, what is important is we're listening to his message and translating it into our lives. >> reporter: at mass he said holiness is tied to little gestures. his gestures here further defining his papacy, stopping hi motorkay to meet a boy with cerebral palsy, blessing an injured philadelphia policeman and 2-year-old jack. >> when he looked at the pope, we had a beautiful moment together. >> reporter: whether up close or far away, francis and america are strangers no more. anne thompson, nbc news, philadelphia. as the pope concludes this remarkable day and week, i'm joined by analyst beneficiary hop robert barron. thank you for being with us. we saw huge crowds through dramatic pictures. we would expect tens of thousands of

catholics to come out for any pope. what did you see that this was different. >> pope benedict was a man of ideas. john paul was a dramatic figure, but this man knows how to use a provocative gesture to symbolize kindness. you've seen the steady line of babies, the pope reaching out to those who are disabled. they see in those gestures christ. you've seen it for about three years, from the very beginning when he bowed down, saying pray for me, paying for his own room, those are the ways he preaches the gospel. >> we think about the airport in philadelphia the other day, reaching out to the young child in the wheelchair, but again, that is something we would expect, that sense of compassion. what did we see in terms of moments? >> one that staying in my mind.

i teared up, i'll confess, when he appeared before congress. here is an event that would have been unthinkable in the 19th century, probably the first half of the 20th century, calling us the land of the free and the home of the brave, and calling upon our best civic principles that align with catholic teachings. as a proud catholic and american, i found that moment deeply moving. >> bishop, good to have you here. >> thank you so much. returning to politics that shows the new poll tightening for donald trump and hillary clinton, as democrat clinton spoke at length today about the e-mail issue that continues to follow her in this campaign, and republican carly fiorina defending what she has said about planned parenthood. kristin welker is at the white house to tell us more on all of this. kristin, good evening. >> reporter: lester, good evening, exclusive interviews on "meet the press" the only two female president yap candidates answered tough questions about recent controversies

and defended their record. >> let me make a couple points. >> reporter: still embattled, secretary hillary clinton acknowledged on "meet the press" today the issue isn't going away anytime soon. >> there is a drip drip drip, and like i said, there's only so much i can control. >> reporter: new signs that the drips are hurting. the latest poll of democratic primary voters shows clinton has lost ground to bernie sanders. she leads him by just seven points, 43 to 35%, a big drop from previous polls. >> i have done all that i can to, you know, take responsibility. >> reporter: but today clinton struggled to explain the discoveries of a string of work e-mails sent on her personal account, earlier than she said she had used the address. >> you said in march that the e-mail system began in march of '09, yet we have the same e-mail address in january. explain that discrepancy. >> there was a transition period.

on my e-mail account, to be clear. >> reporter: she brushed aside the notion that she set up the account to esaid oversight, calling that story ridiculous. she said it was done out of convenience. >> it is the system that my husband's personal office used when he got out of the white house, so it was sitting there in the basement. >> reporter: meanwhile, carly fiorina is rising, while the latest poll shows donald trump still in the lead on the gop side, fiorina has jumped from the bottom rung to third place, tiewood marco rubio at 11%. today fiorina continued to stand by her accusations that planned parenthood officials were caught on camera keeping a fully formed feet actual alive to harvest its brain. >> its heart beating, its legs kicking. >> reporter: several fact checker had determined that the account is not true. >> are you willing to concede that you exaggerated that scene? >> no, not at all.

that scene absolutely does exist. >> reporter: still fiorina continues to gain traction, a reversal of fortunes for the two female candidates in this race. >> i think it means that carly fiorina is doing a lot of things right at exactly the time hillary clinton is either doing things wrong or the things they're trying aren't sticking yet. >> reporter: fiorina also stood by her record as ceo of hewlett-packard which has come under fire because 30,000 people were laid off on her watch. she said those layoffs were necessary to save the company. clinton will spend the first part of the week fund-raising while fiorina will be back on the campaign trail on tuesday. lester? >> kristin, thank you. president obama arrived in new york today for three days of meeting at the united nations on a range of issues, including a highly anticipated meeting with president putin. today the president attended a summit on reducing poverty.

chris jansing is at the u.n. took. >> reporter: this has been often you called the greatest geopolitical show on earth, but also dismissed as no more than that, a show. however, this year world leaders have a number of pressing issues to talk about to the escalating refugee crisis in europe. president obama arrived today for the first of three days, and committed the united states to an ambition 15-year plan to fight poverty and disease. >> we cannot be complacent. many children are just within mosquito bite away from death. that is a moral outrage. it's a profound injustice. it is literally a matter of life and death, and now the world must act. we cannot leave people behind. that speech just a prelude to tomorrow morning when five of the most powerful men in the world will be speaking in a period

of two hours, with often conflicting views of how they see the world. there's anticipation tonight when mr. obama meets fate to face with russian president putin. he hasn't shown up here in a decade and has profound differences over the buildup in syria. also getting buzz tonight, the white house just announced the meeting with a president and raul castro's, castro as first time at the u.n. no shortage of drama this year. one more note. each world leader gets 15 minutes to speak, then a red light goes on, but they often ignore it. moammar gadhafi once famously went six time longer than he was supposed to. lester? >> thank you, chris jansing. at the airport the pop about to leave rome, thanking the organizers here in philadelphia, specifically those who organized the world

meeting the families, which was the centerpiece of his trip to the united states. we'll continue to watch that, and certainly as he travels wherever he goes, pope francis tends to compel listeners to look outside themselves. he challenges them to see their fellow man through a compassionate -- a more compassionate and humble lens. it certainly preceded his american visit and reshaped the way many view and act on their faith, as we found out. even before pope francis set foot in the seminary this weekend, his influence had already made a profound impact. among young men who had answered not just the call of the priesthood, but francis' call for humility and simplicity. some say he walks the walks. >> yes, he does. he is serves others. i want to embody that. >> reporter: phil tran is an 18-year-old immigrant from vietnam who turned down a full engineering

eric tamney is 20. he enrolled shortly after pope francis was named in 2013. >> in grade school and high school, that was the furthest thing from what i wanted. today their paths cross, products of what some have labeled the francis effect, an increase in young men inspired by pope francis psyching to become priests. >> it's a great thing to look up to someone, seeing their characteristics and wanting to apply them to yourself to make you a better person, a better leader. >> reporter: after years of scandal, the seminary head -- >> have you seen it? >> i have. people get excited about pope francis, they hear what he's saying, almost as if it's being heard for the same time. >> reporter: enrollment is up 20% this year, to men from the archdiocese of philadelphia alone,

decade according to bishop senior. nationwide nearly 600 will be ordained in 2015, an increase of more than 100 men last year. is it cool to be catholic again? >> i would say so, yes. >> definitely. >> reporter: while it's impossible to attribute all of it to pope francis, the fascination his visit has generated only reinforces the notion that he is a transformative figure. and one who certainly has raised the bar for these accept seminaryians. >> i wanted to serve the pope in this way. >> reporter: and eager to serve for him. the st. charles seminary has served as the pope's official residence during the philadelphia portion of the visit. there's more to tell you about when we continue on this sunday night. reversing an overdose.

nbc news, thank you for watching, and good night from

in downtown detroit, sunday night football comes to ford field, as the lions look for their first win of the season against the so far undefeated broncos. matthew stafford and his team

lost their first two games on the road. now they hope they can win one at home. to do that, they'll have to defeat the broncos, who despite some rough spots and a new offense have won two straight to open the season. a year after making the playoffs, a 0-2 start has the lions badly needing a win. >> we have not played well consistently. i think against this playoff team it gives us an opportunity to measure up. >> shotgun for machine nning. >> tonight a future hall of famer comes to town with his team at 2-0. >> manning has done it again. >> peyton manning returns to a familiar stage. >> touchdown. 400 career touchdowns. >> number 509. >> he understands now his place in history on sunday night football. and inside ford field now, this is "football night in america."

collinsworth, where about an hour and a half from now we'll be upstairs in the booth with al michaels as they kick it off between the lions and the broncos. we'll kick off with a familiar question. peyton manning always a subject of interest, or fascination. his numbers are unimpressive through the first two weeks. is he in decline at age 39 or is it circumstances surrounding him? >> he has made a few throws where you go what was that, right? and let's just be honest about it. it's not the only thing new that's going on. this is a team with a new head coach, a new offensive coordinator and certainly a new offensive line. there are only three of these guys only in the building a season ago and at the very least every one of these offensive linemen have changed positions, so they're not running the football at all. it doesn't matter if he's under center or in the shotgun, which has also been part of the conversation this year, because you can clearly see that in

decline has been the rushing numbers, whether it's in the shotgun or behind the center. so they have to improve in that area before the passing game will get better. >> if play action is going to work, the running game has to work. averaging 65 yards on the ground through the first two games. c.j. anderson and ronnie hillman have been stopped on losses for 17 of a combined 45 carries. >> remember how well they were running it at the end of last year. everybody thought they were just going to take off and it hasn't happened because of those changes. >> let's check in with michele tafoya who has plenty of good stuff. >> well, the broncos are 2-0 but when peyton manning walked into our production meeting last night, he said with a half smile on his face we're just trying to get our first win on sunday night. no one in denver is happy with the way this offense is playing, so thursday night peyton hosted a dinner for the offense at his home. there was food, lively conversation, including demaryius thomas joking about the fact that after two weeks, a peyton manning-led offense was ranked dead last in the nfl.

but once the dishes were
