Trouble hovering for the hottest gift this holiday season. The battle brewing over the hoverboard. Could this shark be standing in the way of you getting back to the future . And we do say good morning, america and from here in new york we can feel the excitement in the air in washington. Big crowds out to see the pope this morning, and, george, youre smack dab in the middle of it all. Right here on the south lawn. The kr0uds have been gathering for hours. Everyone excited, everyone smiling. Ready to greet pope francis. About 20,000 will be here when president obama greets him in about two hours from now and already there have been such memorable images on this trip. Yesterday the pope touching down around 4 00 p. M. On shepherd one, his plane and going down those steps to set foot on u. S. Soil for the first time in his life. The popes never been to america before. He was greeted, of course, by president obama who brought the whole family with him to Andrews Air Force base and four Young Children chosen from Catholic Schools here in washington, d. C. Presented the pope with flowers before my favorite image of the day yesterday, the pope does not like the trappings of power, drove off squeezed himself into that little fiat before waving goodbye to the crowds. Pope francis with a packed schedule that includes trips to the capitol and the national mall. He is the fourth pope to visit us here in the u. S. And this is the tenth papal visit to america. Hell be the third pope to visit the white house and the first ever to address congress. We are going to have full Team Coverage every step of the way of this historic trip for pope francis. Abcs terry moran has been traveling with the pope, starts us off on the other side of the white house on the north lawn. Hey, terry. Reporter hey, george. The pope is going to arrive here at the white house to a lot of pomp and circumstance and pageantry for a man who we pointed out prefers simplicity but he and president obama share a lot on their agenda and, in fact, the president is hoping the pope can boost his agenda. It was a moment to remember, the popes plane shepherd one its been dubbed touched down. The honor guard and the flags, the president and the Vice President and their families and a crowd that let out a very american cheer. All hey, hey, welcome to the usa. Reporter then francis stepped out removed his sue ket that before it blew away and came down the stairs to a warm greeting from president obama. Your holiness, it is so nice to see you, welcome. Were so glad to have you. Reporter the crowd cheering every smile, every glance from the pontiff. And then this was pure francis. That car, a fiat 500, he squeezed into it and promptly rolled the windows down and then set off sandwiched in that motorcade among the hulking suvs. This is the popes motorcade, the little fiat going along here. Reporter he begins his American Journey knowing full well the controversy hes creating with his Progressive Agenda on Climate Change and inequality. On board the papal plane on route to washington he came back to answer a few questions from reporters and took on the conservative critique of him when he was asked specifically about this newsweek cover, is the Pope Catholic . [ speaking a Foreign Language ] reporter some people think im a bit leftist. I am certain i have not said one thing not within the doctrine. He will chart his own course and one more thing, hes generous on the flight over here, francis sent back some of the special papal lasagna he gets served and it was good, george. Ill bet it was, terry. Thanks very much. Want to go to cecilia vega. She is out on the ellipse where the pope will have the parade, the popemobile and the crowds already gathering, cecilia. Reporter gathering, these guys are so excited. Good morning. Look at all these people. Thousands already this early in the morning. I want to show you theyve been sleeping out here. You got here what time . 5 00 p. M. Reporter they said its better than black friday. If you wait for that you might wait for the pope. Its not just this, all the way across the shadow of the Washington Monument waiting to see pope francis in the popemobile. This crowd goes all the way down here. I asked them, its like you are waiting to see britney spears, better, robin, its the pope all here to catch a glimpse of pope francis. Much better, cecilia, thank you. Ironclad security in place to protect the pope and those massive crowds you see every step of the way and abcs Pierre Thomas is in washington with that part of the story. Good morning, pierre. Reporter good morning, robin. The security is unprecedented. In a couple of hours the pope and the president will greet 15,000 people on the south white house lawn. All those people had to go through magnetometers and background check, Law Enforcement being pushed to the limit. Amtrak seeing huge crowd, tens of thousands expected to flood into the city to glimpse the pope and while hes moving around washington theres heart that heart in the mouth moment for Law Enforcement when he might get out of the car and touch the people. Theres no specific threat. Undercover officers in the crowds, s. W. A. T. Teams standing by. Snipers along the parade route. Authorities are leaving nothing to chance, robin. He is the pope for the people. He likes to get out and be with people. George, of course, is there with you in washington. Pierre, with a special guest. We want to get more on this now from father jim martin from america magazine, our expert for the pope. Father jim, we saw the pope yesterday. Were going to hear from him for the first time today at the white house. And what is the popes core message on this trip . Of course, the core message is the gospel. He wants to kind of proclaim jesus christ to everyone he meets and help the people meet god in a new way but i think his more specifically he might talk about income inequality and the poor which is a theme hes been highlighting and certainly the environment the theme of his encyclical and refugees and migrants a problem not only in the United States but also worldwide thats a Progressive Agenda but the pope does not fit neatly into our political categories. No, he doesnt. The Catholic Church transcends categories like liberal and conservative and certainly democrat and republican. Hes preaching the gospel, what he sees to be jesus call to care for the poor but also the earth and if that has a political bent to it i think he says to himself so be it. Jim, what do you think the pope will enjoy most about this trip . Thats a great question. I think meeting people. He has said obviously hes not been in the United States before. He most gets to know a country when he meets people so i think this will be a learning experience for him too. You will see him, i believe, get progressively more and more comfortable with the United States and certainly with americans so he wants to meet part of his flock in the United States. When you include the trip to cuba shall the three stops here in the United States, this will be the longest papal mission. What a success for the vatican. Success is having more people come to god and have more meet jesus christ but certainly proclaiming his message of the poor, i think through not only words but also deeds, youll see him with the homeless in washington with prisoners in philadelphia and with schoolchildren in harlem so i think to sort of proclaim the gospel by what he does and what he says. Thanks for that, father martin. Youll be with us on the entire trip. Now back to robin. Stay right here for the latest coverage of pope francis here in america. But now to that deadly flash flooding overnight. Powerful storms sweeping through the southwest and, ginger, i know you have your eye on it. Over an inch and a half that did this in albuquerque, new mexico. The creek, this is one of the wettest days theyve had in september. A very dry one. Put that water on the desert land and the fire trucks surrounded by the water. The rescues were on. One person unfortunately found dead in one of the washes. Now were going with the Flash Flood Watches because the moisture has moved up into another system in the plains, parts of nebraska east of omaha under a Flash Flood Warning and more of that will move from minneapolis to north platte. Weve got 1 to 2 inches. 2 to 3 inches in that red bullseye. Flash flooding could become an issue. A whole lot more coming up. For now back to george. Okay, race for president. Your voice, your vote and donald trump back on late night tv last night talking to Stephen Colbert. Also firing back against his rivals. While ben carson is backtracking on those comments, his controversial comments he made about muslims. Tom llamas tracking it all. Good morning, tom. Reporter good morning to you. Some candidates were growing in popularity earlier had stayed out of Donald Trumps way now sharpening their attacks. As the frontrunner just gets stronger and dr. Ben carson still drawing huge crowds and tells me what it would take for him to vote for a muslim to be president. Donald trump. Reporter overnight donald trump taking his campaign to late night. You are setting the world on fire right now. Well, were having a lot of fun and i think were hitting some pretty good issues. Reporter as trump was yucking it up. Anybody youd like to apologize to yourself right now . No. No . Reporter his rivals going after him hard. It might seem that Donald Trumps getting a little nervous, all of us will be revealed over time and under pressure. Up to now he hasnt answered serious questions about National Security and until he does there should be concerns. Reporter trump then slamming rubio over immigration tweeting senator marco amnesty rubio who has worst voting record in senate just hit me on National Security but i said dont go into iraq, vision. Meanwhile, dr. Ben carson trying to clarify what he meant when he said he would not support a muslim becoming president. I have subsequently said if it was a christian running for president but they wanted to impose a theocracy i would not support that either. Why would a muslim not do that. Traditionally islam does not separate church and state. So they obviously are going to have to do a fairly significant departure from what they traditionally do which is fine. Reporter now, dr. Carson tells me his campaign has reached out to muslimamerican groups to discuss any issues they have and, robin, if you were wondering, donald trump still hates fox newss megyn kelly calling her a lightweight on twitter and should take another vacation. Thank you. To that scandal rocking vokou volkswagen. The ceo is under fire as you know facing calls to resign and the company now faces countless lawsuits from angry customers. Abcs david kerley has the latest. Reporter with the vw Board Holding emergency meetings its ceo apologizing again. [ speaking a Foreign Language ] reporter its stock plummeting valued down 35 as authorities consider criminal charges with vw now admitting 11 million diesel cars were built to cheat testing. Here at the emissions stations. Pass, pass, pass, everything. Starting in 2009 models vw inserted software sensed when its hooked up for a check and the controls limiting emissions switch on and after the test the controls switched off meaning the car would perform better but would emit illegal levels of pollutant, up to 40 times higher than allowed. Already some customers are suing. Ari levin bout a yet that in 2009 thinking he was being environme environmentally friendly and now feels guilty about driving his car. Every reason that i bought the car was based on a lie that volkswagen created and advertised. Reporter that one of several class action lawsuits already filed. California and epa officials discovered the cheat. It seems remarkable that a company this big would take this kind of a risk. It is completely incomprehensible to me. Reporter the epa continues to investigate and the department of justice has criminal investigators looking at this case. That big Board Meeting of vw set for friday morning. Dont be surprised if something happens beforehand too, robin. Probably so, david. Thank you. Now amy with the mornings other top stories starting with an emotional reunion. Thats right, robin.

We remember him not just for his hall of fame career with the yankees but also his respected view on life and his world famous sayings known as yogiisms. A towering figure at only 57 he was one of the sports most beloved icons on and off the field. Yogi berra runs out there. Reporter a fierce competitor. The legendary yankees catcher a threetime mvp, 15time allstar and holder of seven world series records. And playing 17 years with the yankees being in 14 world series we won 10 of them. But he was just as famous for his colorful off the field observation, his yogiisms. If you come to a fork in the road, take it. Classic quotes like it aint over till its over and the future aint what it used to be to be repeated for years to come. Deja vu all over again as yogi berra would say. Where do these things come from, yogi. I dont even know. I dont even know i say them myself. I dont make them up. He died of Natural Causes survived by three sons and 11 grandchildren but his legacy will live on and on. We looked up some of his famous yogiisms. When you come to the fork in the road, take it. Like he said, so simple like that. He was always about town. So charitable and an icon. He will be missed. Lived a full, full life. Absolutely. All right.

We have yet to decide what that price will be, but after reviewing all of our costs, we will decide to lower the piece to a point where the Company Makes a small and marginal profit. Reporter the increase got the attention of Hillary Clinton who called it outrageous in a tweet and laid out her plan demanding change. You wont have to pay more than 250 a month for covered medications. Reporter but shkreli says hes making a commitment to the thousands who need the drug.
