>> alan: i want one of welcome to "world news." tonight, the race is on. the gloves come off. tonight, president obama unleashes his first review of the brand new romney/ryan ticket. >> it's a vision that i fundamentally disagree with. >> from his own battle lines tonight as the new republican duo hits the battleground states. we learn about the mission impossible. paul ryan's dash in the woods. it worked. crash course. a u.s. navy ship colliding with a giant oil tanker. in one of the most tense waterways in the world. how did it hp? martha raddatz stands by. and the dust, the blinding dust over a major american city. the blinding dust this evening. tonight, we take you inside the storm. and the dramatic dive. the american who wasn't supposed to make the cut and dove into gold. his chinese competitor crushed.

and the olympic images, it takes 3,000 clicks to capture one golden moment. good evening on this sunday night. we begin here as the presidential race takes on a new intensity this evening. the nation introduced to the romney/ryan ticket. this image from wisconsin where supporters gathered to welcome mitt romney and paul ryan right there in ryan's home state. they have the frame there, america's comeback team. they have made tops in virginia and north carolina and now we are hearing from the president, taking the stage a short time ago offering his own review of the ticket, welcoming paul ryan to the race. but it was what he said after that that drew cheers from his own supporters. it's your voice, your voice and we have it all covered with jon karl on the trail with the romney campaign tonight.

>> reporter: for mitt romney, a running mate at his side and some of his biggest crowds of his campaign -- >> this is day two on our comeback tour to get america strong again. we're going to recapture something which some people thought was lost. >> reporter: in mooresville, north carolina -- packed to capacity inside and several thousand more in an overflow area outside. >> they were able to pass their entire legislative agenda, virtually. what we got was stimulus. obama care. you know what, north carolina? we can do better than this. >> reporter: down the road in high point, an even bigger crowd. >> our founders made it really explicit. our rights come from nature and god and not from government. >> reporter: romney's wife, ann,

seemed to be caught up in the excitement. jumping on stage to talk to the crowd for the first time in over a month. >> we are not going to take it anymore. we are taking the white house back. >> reporter: ryan's wife, janna, came onstage, too, but decided not to take the mike. >> reporter: after wisconsin, the ryan/romney show will slit for a while as romney heads to florida and ryan in iowa. two candidates and a chance to cover twice as up. ground. david? >> jon karl, thanks. president obama weighing in on mitt romney's choice. kind words and fighting words. david kerley tonight with that part of the story. david? >> reporter: good evening, david. he did come out swinging but first he welcomed paul ryan to the race. he called him the ideological leader of republican congress. >> i want to congratulate -- no, no, i want to the congratulate congressman ryan. i know him.

i welcome him to the race. congressman ryan is a decent man. he is a family man. >> reporter: but mr. obama quickly attacked what he called the top down romney/ryan economic plan. >> they have tried this before. they have tried to sell us this trickle down fairy dust before and guess what? it did not work. >> reporter: in chicago today, the number of mr. obama's fund-raisers hit 200. but his first stop was campaign headquarters where they plan for the next political landscape. and democrats bombarded the airways. calling ryan radical, extreme, a right wing ideologue. he claims too make medicare and tax cuts to the rich the center of the campaign. the president already has. >> it is a trojan house. disguised as debt reduction plans is really an attempt to

impose a radical vision on the country. >> reporter: while the ryan pick has brought excitement and bigger crowds, they say it makes it harder for republicans in crucial states, among them, florida and ohio. because talk of changing medicare could anger and motivate seniors. >> he is trying to move to the middle and ryan makes it almost impossible to do that. ryan wants a voucher program for medicare. some of the independents -- seniors. >> reporter: over the next three days, the president will campaign in one of the crucial state, iowa. there were five fund-raisers today, $6.5 million. as we mentioned, 200. that is a record. by this time in his first term, george bush had only done 88 fund-raisers, david? >> david kerley at the white house tonight. david, thanks to you. want to bring in abc's cokie roberts in the washington burrow tonight. as we heard david report there. this obama campaign had long planned to tie the paul ryan budget to the campaign. now they have a romney/ryan ticket.

does it make it easier? >> does it ever? and you know the democrats have been running against the ryan budget for a couple years now. they have made paul ryan into something of a boogie man and used his proposals to, as they put it in medicare as we know and in congressional races and think think they have won a couple elections just by going after paul ryan and his budgets. they are dancing in the streets right now. >> on the flip side, we heard you this morning on "this week" saying paul ryan can address the budget with a smile on his face. he got some chuckles. that is an important point. >> absolutely. he is a happy warrior and that in the mold of ronald reagan and jack kemp. and that is why conservatives are excited. that's a big plus for mitt romney, there is excitement now around that ticket and people are turning out now to see them. and conservatives are just singing paul ryan's praises. this is a pick that obviously has its pluses as well as its minuses. >> all right, that to you,

cokie. great to have you with us. and last night, we told you about the mission impossible, the aim to keep the v.p. pick a secret. even with the stake out in front of paul ryan's home. turns out the running mate escaped through the woods. one of our own is staked out in front of paul ryan's janesville, wisconsin, home. it's what we do every four years, tracking the movements of potential v.p. picks. he did appear mid afternoon friday, dropped off by an aide. walking up his driveway. he said his wife wasn't home and he was locked out. he lost his keys. and as it turns out. as we later expected that moment was part of the plan. when ryan went around the back to get in, that was the last we would see of him. the aide was driving to the other side of the neighborhood and waiting for him. he would dash into the woods behind his home, the same

neighborhood where he grew up and went to a truck waiting for him. he talked about that. >> the house i grew up in backs up to the house i live in now. so i know the woods like the back of my hand. it wasn't too hard. i just went out my back-door and i went over the gully and i went over the tree in the fort i built and went out next to the drive way i grew up in. >> in the woods, the house that he grew up in and the truck with his aide inside. he was driven to an airport and flown to elizabeth city, north carolina and driven to norfolk, virginia, to meet up with the romneys. all the while, the team outside his home, the lights on and off, the tv on upstairs. the ryans, long gone. >> it does turn out there was someone in the home when the lights were going on and off. it was ryan's sister-in-law. perhaps helping out with it all. 86 days now until election day.

we'll be there every step of the way. we move on to the other headline overseas. a collision between a u.s. navy ship and an oil tanker. in waterways with so much of the world's oil passes through. abc's correspondent martha raddatz on how it happened. >> reporter: it is a major embarrassment for the navy. "the uss porter," a billion-dollar guided missile destroyer left with a gaping hole. we were on a destroyer earlier in the strait and how then how difficult the transit can be. the shipping lane itself is about two miles wide. so there is very little room to maneuver. that is the "uss abraham lincoln" behind me. but the way the porter maneuvered seemed to break all the rules of navigation. but the navy ship was just exiting the strait in the gulf. the japanese tanker, twice the

size of the destroyer, was entering the strait. ship traffic is much like car traffic. each vessel is stay in the right. instead, the "uss porter" turned left into the bigger tanker. >> it's inexplicable why a warship world turn into a super tanker. >> reporter: fortunately, there are no injuries but the ship's captain will almost certainly be relieved of command. this also takes the destroyer out of commission at a critical time when the u.s. is trying to build up missile defenses in the gulf in case israel attacks iran and iran tries to retaliate against u.s. ships. david? >> martha, thank you. in egypt, a bold move from the first freely elected president. mohamed morsi forced the resignation of the defense minister and the chief of staff. he canceled the amendments the military had imposed.

he wants to get back that power. and iran, the search for survivors came to an end after to back-to-back earthquakes there. they found 250 people dead in the villages. the quakes struck 11 minutes apart. back in the u.s. tonight, trying to keep a huge wildfire from reaching neighborhoods in fresno, california. at least 40 homes have been evacuated tonight. fans flamed by hot, dry winds with temperatures near 100. >> back in this country, the same hot and dry weather, the driving force behind giant dust storm that engulfed phoenix this weekend. tonight, ginger zee takes us inside the storm. >> it's totally dark out. >> reporter: swallowing cities whole. from blue to brown in seconds. >> wow. oh, shoot, that is scary. >> reporter: another blinding dust storm rolled through the phoenix area this weekend. >> yeah, i'm surrounded by it. you see blue, blue, blue, bad, bad. >> reporter: it's a monstrous swirl of dust. we have seen it from afar. what is it like inside?

>> it got really, really dark really, really fast. the more i looked at the dust storm and i realize, it's massively huge. >> reporter: trapped inside a huge cloud, breathing can be difficult. dust can choke visibility to zero. highways come to an absolute halt. the fast moving wall of dust and debris can be miles long and thousands of feet high. here is how it forms. when thunderstorms begin to die out and collapse, rain-cooled air rushes to ground. and that kicks up dust and sends it rolling. may seem like you may have seen more dust storms recently and one of the reasons is extreme heat. phoenix is under heat warnings this whole weekend, that is 110 and above. that is extra fuel for the thunderstorms that make the dust storms. >> extraordinary so see from the skies. ginger zee, thank you. we have good now about congresswoman gabby giffords. a year and a half after that tucson shooting. another hurdle crossed.

giffords is going home to arizona. she and her husband had been living in houston and today a tweet that made us all smile here. her husband tweeting, moving back to tucson today. gabby has been waiting for that day for a long time. we are cheering her on. and in london, the olympic games have come to an end. the after party now under way. and not without a golden moment for the americans. the dramatic drive. look a this. a golden dive right there. jeffrey kofman is in london tonight. jeffrey? >> reporter: good evening to you, david, yes, it is over. for team usa, it was 16 incredible days in sunny london that kept raining gold. >> the lob from lebron. >> reporter: the men's basketball dream team faced sobering reality in a series of tough matches but this afternoon, they triumphed over spain and today got the gold.

no one expected david boudia to get gold. but look a this, a ten meter plunge close to perfection. >> he's got it! >> reporter: not bad for a guy who confessed he had a fear of heights. the champion from china was expecting to wear gold. when he had to settle with silver, he was shattered. the first american diving gold since greg louganis in 1988. in 16 days, 45 american gold medals. phelps, franklin, so many others that are household names. the best medal hold for team usa at a full olympics ever. and what an olympics. remember three weeks an i ago when the olympics were approaching and all the talk was about chaos and congestion and a breakdown of security? what happened? nothing. even the weather cooperated. they are calling these the golden games. >> it's easy to maneuver. there are always people around pointing us this way. i think it was well done. >> smashing success. >> reporter: and tonight a huge

party to celebrate. the athletes, the host city, the world came together to say to london, well done. and over to you, rio. in four years, brazil will host the very first olympics in south america and as original as these games were, you can expect something very different down there. david? >> pack your bags. jeffrey, thanks for your coverage all the way through. still ahead, the dramatic moment in las vegas after a chimp breaks free and it's not the first time the chimp has pulled it off. and later here tonight, the picture perfect olympic moments. they are not as easy to capture as you think. photographers wearing scuba fear and standing on porto potties to capture them. photographers wearing scuba fear and standing on porto potties to catch them. staying active can actually ease arthritis symptoms. but if you have arthritis, staying active can be difficult. prescription celebrex can help relieve arthritis pain

you have heard the saying what happens in vegas stays in vegas. tonight, the biggest challenge is getting a chimp to stay. and it isn't the first time she got free. john schriffen with the story tonight. >> another chimpanzee escape in las vegas. >> reporter: for the second time in nearly a month c.j. escaped from a backyard cage sending fear through a neighborhood. the last time c.j. and her mate, buddy, broke out of their enclosure and even were banging on a police car. >> they are dangerous. bring shotguns. i'm serious. they are wild animals. >> after buddy headed to a group
