Morning. Dont you dare look back home run on hometown night on dancing with the stars. Bindi rocking to the top spot. Tamar hot on her heels. And legendary grammywinner chaka khan the first booted from the ballroom. Shes happy to be going home. Shut up and dance with me we do say good morning, america. And chaka, in your words, i feel for you. Man, she gave it her all with keo. But she is the first to leave the dance floor. And another couple will go home tonight. Yeah, they are wasting no time in getting right to it on dancing with the stars. Also this morning, big exclusive right here, kim davis, that kentucky county clerk, you see her there with paula faris, her first interview since all that controversy since her jailing. Well have that coming up. But right now, were just hours away from pope francis arriving here on his historic visit to america. He lands in washington this afternoon arriving from cuba. And abcs terry moran is there with the pope right now as he wraps up an emotional visit. Good morning, terry. Reporter good morning, george. These are pope francis last few hours here in cuba. Its been an incredible trip. The people here greeting the first latinamerican pope almost as a brother, and yet he heads off to america where hes expected to stir up some controversy on inequality and Global Climate change. But here in cuba, francis has carefully avoided creating any controversy. Overnight, a classic pope francis moment. At the end of a long day no limousine for him. Or even a private car. Instead, a minibus to take him to the seminary where he spent the night. All part of this popes simple style like his visit last night to cubas most sacred shrine. And this morning, francis celebrated a farewell mass here. They didnt want to let him go. Everywhere he goes in cuba francis reaches out on their terms in their language like when he celebrated mass in holguin, cubas Third Largest city. And challenged cubans, and their government, which still jails people for being counterrevolutionary traitors. Do you believe it is possible, francis asks, that a traitor can become a friend . A gentle rebuke but no more. And no meeting with any cuban dissidents even as he paid a cordial visit to fidel castro who built the repressive regime here. And francis has faced criticism here and in the United States over those matters. But those who are close to him say this is not a pope who is trying to inspire political change. Hes after Something Else, they say. Hes preaching the gospel. Robin . All right, terry, thank you. The pope arrives in washington this afternoon for his threecity whirlwind u. S. Tour which also includes new york and philadelphia. While here, francis, pope francis will say four masses. And make a total of 24 public appearances including at the national mall, central park and independence hall. Abcs cecilia vega is in washington this morning where they have rolled out the red carpet. Good morning, cecilia. Reporter good morning, robin. Not only is that red carpet out there are a lot of barricades all over the city, too. As you can see right here behind me. This is going to be a historic visit filled with pomp and circumstance but the very first thing pope francis will see when he arrives later today at Andrews Air Force base is the president and the first family. This is a very rare gesture for a president to show up to an airplane, afforded to very few dignitaries. The highlights for washington, d. C. , of course, that white house visit, 15,000 people expected at the white house lawn and, of course, that historic first ever papal address to congress. Now, congress has been warned, there are rules about these things. What you wont see this time around like you do at the state of the union, those fist bumps, those hand shakes. As the pope walks down the aisle. This is the house where the pope is going to be spending his evenings here in d. C. Right across the street from the Vice President s mansion. I havent i know its hard to believe been invited inside. Its supposed to be much lovelier than the digs where pope francis stays back in the vatican. Robin . Im sure your invitation was lost in the mail, cecilia, thank you. Abc news has live coverage of pope francis in america all week long, beginning with his arrival in d. C. , at approximately 4 00 p. M. Eastern time the afternoon. And, george, i know youre heading there right after gma. He lands at Andrews Air Force base. The race for president now. Your voice, you vote. And a big shakeup in the race. Wisconsin Governor Scott walker drops out and calls on republicans to stop donald trump as ben carson defies calls to drop out for his comments about muslims. Abcs tom llamas is on the trail with carsen in shar sharonville, ohio. Good morning, tom. Reporter george, good morning. The Walker Campaign lasting only 71 days. One of the shortest in recent memories. I was actually speaking with donald trump as walker was resigning. And like many others, he couldnt believe it was happening so early. This morning, trump is taking the high road. Not slamming walker. Even though walker says trump needs to be beaten. This morning, a onetime frontrunner dropping out of the gop race for president. I will suspend my campaign immediately. Reporter sources say a Campaign Cash crunch forced wisconsin Governor Scott walker to call it quits. Walker, slamming current republican frontrunner donald trump on his way out. I encourage other republican president ial candidates to consider doing the same so that the voters can focus on a limited number of candidates who can offer a positive, conservative alternative to the current frontrunner. Reporter i spoke with trump about the narrowing field while walker was resigning. Well, im surprised but i think he did the right thing and i think you have others that should drop out. Because if you look at some of the numbers where theyre at zero or 1 . But many are less than 1 . Reporter some calling for dr. Ben carson to drop out after he said this. I would not advocate we put a muslim in charge of this nation. I absolutely would not agree with that. Reporter but overnight changing his tune, saying he meant radical islamists, not moderate muslims. I dont care what religion or faith someone belongs to, if theyre willing to subjugate that to the american way and to our constitution, then i have no problem with it. Reporter Carly Fiorina now in second place according to the latest national poll, coming out strong on this topic late last night. Well, i think thats wrong. Whether its a person of Christian Faith or jewish faith or muslim faith or other faith, i think faith gives us humility and empathy and optimism. And i think those are important things. Reporter now dr. Carson says his comments werent that controversial. He says after he made those comments on sunday morning, his Facebook Page went up by more than 100,000 likes. Thats one piece of evidence. Okay, tom, thanks very much. Lets talk about it with matthew dowd. Scott walker says he ran out of money but there were reasons he ran out of money. This is the first number one seed to get kicked out of the tournament. In homage to the pope, this is like germany losing in the group stage of a world cup. He dominated the polls for awhile. It tells us two things, first a good candidate on paper doesnt always meet reality well. And i think thats scott walker. If youre a. 300 hitter in the minor leagues, it doesnt mean you can visithit a curveball in show. The second thing, i think, how much the debates matter. They took walker in double digits to an asterisk in two debates. Carly fiorina who wasnt in the main event, is now in the top three. Jeb bush was number one and two and now number five. Who is helped most by this . You can see who the vultures picking over the dead carcass of scott walker who is taking what contributors. Right now, ted cruz, jeb bush, marco rubio look like theyre picking up the most support. But keep an eye on kasich. He is the last midwesterner in the race, the midwestern states are all winner take all when we get towards the end of the primary. And he actually could make a play in iowa. Carly fiorina had a light moment on the tonight show. Lets take a look. My name is snick and im lazy please dont take a walk with me id rather stay right here at home instead i want to lie back down in my nice warm bed my name is snick and youre going to have to carry me a different side of Carly Fiorina right there. And we now have two races in the republican party. You have to watch these kind of things. You want to be human but you dont want to look like youre embarrassing yourself. Outsiders versus insiders, fiorina, carson, and donald trump will battle over that. And then the insiders who will battle over that. It will be an outsideinside race. Fascinating race. Matthew dowd, thanks very much. Interesting days. Now to a mystery in the sky. An American Airlines flight from North Carolina to connecticut forced to make an Emergency Landing last night after something caused the windshield to crack. Abcs david kerley is in washington with the latest. Good morning, david. Reporter morning, robin. It is a big question this morning. How did a jets windshield crack, really shatter in flight when it didnt hit birds, didnt fly through weather . The American Airlines flight was from charlotte headed to connecticut. Just south of philly, the first officer sees this crack in front of him and the windshield shattering on the a319. So they asked for an Emergency Landing in philly. Heres what they told air traffic control. Ah, yeah, the right windshield is completely shattered. Reporter they landed safely. The 114 passengers got on another jet to continue their flight. We have seen in the past what hail can and birds can do to windshields. Remember those pictures from denver hail shattering both sides of the windshields. But american says weather and birds were not a factor last night. So they will be looking for other causes. Was it a defect . Something else . But because philly was a hub the windshield was replaced overnight and that jet will be back in service today. Oh, my goodness. Well, hopefully, theyll find out what happened. All right, david, thank you. We turn to an unprecedented punishment for a corporate executive. Former Peanut Company chief Stewart Parnell sentenced to 28 years in prison for knowingly selling tainted Peanut Butter blamed for nine deaths. He could spend the rest of his life in prison. Steve osunsami has the story. Good morning, steve. Reporter good morning, george. This former ceo is already 61 years old. So theyre calling this a virtual life sentence. This morning, a first of its kind decision in a loud and clear message about safety to americas food industry. The food safety lost out to greed. Reporter former Peanut Company ceo Stewart Parnell is in an albany, georgia, jail cell right now. A federal judge sentenced him to 28 years monday after one of his roasting plants was blamed for a deadly outbreak of salmonella in 2008. Nine people died. 714 got sick across 46 states. At trial, prosecutors shared emails where they say parnell pushed employees to sell tainted food, saying, just ship it. I cannot afford to lose another customer. Gabrielle meunier was one of those customers. Her son christopher was 7 years old when he got sick. She spoke at parnells sentencing. I have to tell you, when i first spotted him, i wanted to cry. I feel badly, this should never have happened. This never should have happened to begin with. Reporter theyre holding executives and even farmers responsible for dangerous outbreaks. Two egg executives got sentences after a 2010 salmonella outbreak. Last year two cantaloupe farmers were sentenced to five years probation and six months home detention for a listeria outbreak in 2011. But parnells nearly threedecade prison sentence is the stiffest punishment the industry has ever seen. My mother shirley beat cancer. And died from eating Peanut Butter. Today was a victory. It was justice for her a other families who needlessly suffered and ate food that they believed to be properly processed. Reporter parnell isnt the only former executive at his Company Facing real time. His brother was sentenced to 20 years. Another manager sentenced to five. Robin . All right, steve, those comments from the victims families. My goodness. Flash flooding in the southwest and powerful storms closing roads and knocking out power. And ginger, more rain is in the forecast . Yes, more rain. And the Flash Flood Watch is still on for at least a few more hours this morning. From rio rico, arizona, washes over the roads. Do not drive on through that. Up to 4. 6 inches of rain. Most of it just outside tucson washing over the roads closing several of them. And of course, causing several accidents. So, again, two pockets of Flash Flood Watches in new mexico and southern california. These actually go through this evening so well watch that. On the backlash of that low and all the moisture pools up into the plains. So the next spot well watch for heavy rain is in kansas and nebraska. A whole lot more coming up. Good to have you back and now amy has the other top stories starting with the rising cost of Prescription Drugs. Thats right. Wall street is reacting to a new proposal from hillary clinton. She wants to cap Prescription Drug prices for some patients at 250 per month. Word of that plan sent biotech and drug stocks plunging. It comes amid growing outrage over a 5,000 increase in the price of a drug used by cancer and aids patients. Clinton calls that pricegouging. A texas businesswoman under arrest in china accused of spying. Sandy phangillis has been in chinese custody since march, when she was part of a delegation visiting china. Her husband calling the charges ridiculous and wants president obama to raise the case when chinas president visits washington this week. In california, a navy jet crashed into this field near fresno. You can see there the smoke rising from the site. The pilot thankfully ejected just moments earlier and is okay this morning. The 30 million jet, though, is a total loss. A violent crash at this racetrack in europe. Watch as the car careens out of control, slamming into a fence, launching into the air, and rolling at least half a dozen times. Somehow miraculously that driver was able to walk away from the site. Apple is reportedly speeding up plans to build an electric car. We do not know what it will look like yet. But the internet is full of potential designs, like that one. The wall street journal says it could go on sale in 2019. And finally, whats 468 feet long and costs more than 400 million . Answer, a russian billionaires new recordbreaking superyacht. It is the Worlds Largest sailing ship, the masts climb 300 feet into the sky. It features eight floors. Eight floors, a pool, helicopter pad, and an underwater observation deck. The windows were even made of bombproof glass. And the ship can host 20 people. Thats it . And requires wow. But you need 54 crew members to get this baby on the water. But you know what they say about the two best days of a boat owners life . The day you buy the boat and the day you sell the boat. Is that true for this one . I dont know about this one. You need a lot of champagne too to get that thing started. To crash it. Im with you. Only 20 people for 400 million bucks. Okay, amy, thanks very much. A major scandal at volkswagen. Affecting millions of car owners. What it could mean for you in just 30 seconds. Volkswagen is bracing for billions in fines, possible criminal charges for its executives as the company apologized for rigging 11 million cars to help it beat emission tests. Abcs t. J. Holmes here. And t. J. , volkswagen also facing millions of angry customers. Reporter a lot of angry customers. Thats no reason for us to mince words here, george. Volkswagen cheated and got caught and millions of people have been putting out a much bigger Carbon Footprint than they were led to believe. Overnight volkswagen throwing a huge party to celebrate their new line of passats, including this energetic performance by lenny kravitz. But the other headline at the event, a huge company mea culpa. Weve totally screwed up. Reporter volkswagen ceo michael horn acknowledging the company knowingly sold 500,000 dieselpowered cars in america which intentionally faked emissions tests. Customers in their cars emitting as much as 40 times the legal pollution limit. So lets be clear about this. Our company was dishonest. Reporter now the german automakers face billions in fines, while their executives could face criminal charges. Volkswagen admitted they intentionally put these Software Programs to go to a cleaner mode during official emissions testing. A fact not lost on its loyal fan base thinking they were environmentally friendly. Regardless of how much they have fudged by, its the fact that they lied in the first place because thats going to give me concern. Reporter volkswagen halted all u. S. Sales of the diesel cars and pledged to cooperate with regulators. Still the show went on last night, the company hoping to focus on its future rather than its admitted deception of the past. I know, robin. You threw your hands up at the party going on. You want to distract attention. This is not like recalls we have seen in the past where somebody made a mistake. They did this on purpose. 11 million cars worldwide and theyve already set aside some 7 billion to deal with fines. Could get 18 billion in fines just here. And people might want their cars back. You think youre driving environmentally friendly. Youre out there just putting it out. All right, t. J. Thanks. All right. Ahead this morning, an abc news exclusive.
