we'll be back at 6:00 with more. see you then. i'm david muir. tonight on "world news" from tucson, after the tragedy. the first test in washington now. arizona senator john mccain praising his one-time opponent, president obama, on his push for greater civility. but what will last? climbing back. the congresswoman and her remarkable recovery. what doctors have done here this weekend, and why this next week is so crucial. the town hall. after that meeting outside the safeway was cut short one week ago, the survivors and the heroes who saved them, determined to continue that conversation, all together for the first time. >> this is the hero. if i'm a hero, he's a super hero. the family feud. why one of ronald reagan's children is now lashing out at another. and, here in tucson, christina's gift, to the friends she left behind. the boy in the

stands, the girl on the field. tonight, their simple message for our country. and good evening from tucson. where tonight, a community so tested, having endured such pain is clearly trying to move past this. this morning, a special town hall on "this week." so many of the survivors and heroes who saved them, many who gathered at that safeway one week ago, were back together, determined to continue the conversation cut short. and something we hadn't heard about the gunman before, from a neighbor who was silent until now. tonight, good news about the congresswoman. her condition has been upgraded from critical to serious, now that she's off the ventilator. and here in arizona, senator john mccain for praise for his former rival, president obama, after his call for more civility in our national conversation. but that will be tested this week, and very quickly. and so we start with david kerley in washington tonight. david? >> reporter: good evening, david. it is the talk of the town here. will republicans and democrats actually change the tone of their talking?

the first family went to church this morning, where there were prayers for those in tucson, and praise for the president's leadership, including his speech calling for civility, which both sides heard. >> i think that we republicans and i think democrats alike will realize that if we tone down the rhetoric sometimes, our debate is more effective from our own side. >> reporter: but even the name on the first bill to come up this week contains some fighting words. >> this is a job-killing bill. >> job-killing. >> job-killing legislation. >> reporter: it's right there in the title. the repeal of the job-killing health care law. but this weekend, speaker john boehner dropped the word killing and instead said they will fight democrats' job-destroying spending spread. republicans say don't make too much of the name change. >> republicans want to get a bill before the state of the union. they want to put this marker down. and that the president is going to have to answer to this. >> reporter: at the state of the union, rather than republicans and democrats sitting apart,

there is a call for the two sides to mingle. democrat chuck schumer and republican tom coburn say they will sit town. >> that's symbolic but maybe it just sets a tone and everything get as little bit more civil. >> some of the problems in our country is, we talk past each other, not to each other. >> reporter: john mccain went even further in an opinion piece in "the washington post" this morning, praising the president, saying, quote, i believe he is a patriot. i reject accusations that the president is unworthy to lead america. but experts believe all this civility may be short-lived. >> president obama's speech, as good as it was, won't have a long-term effect. that within a week or two, the parties will be back to fighting against health care, people will be attacking obama as evil and vice versa. >> reporter: the experts point to the time after 9/11. there was an effort to turn down the rhetoric then. it did not last long. politics by their nature are contentious. we'll see if it practitioners can maintain the civility. david? >> david kerley in washington

tonight starting us off. david, thank you. and back here in tucson, it was the meeting they never had. cut short one week ago at that safeway. the survivors and the people who saved them, determined to return to continue that conversation. all in the same room for the first time. i joined christiane amanpour this morning for a special "this week" town hall and we began by asking how many in that room were there or knew someone hurt in the shootings. >> show me by a show of hands. so, practically the whole room. this whole community has been so touched. >> reporter: it was bill heilman's wife who brought that little girl, christina-taylor green, a neighbor's daughter. she was so excited to meet her congresswoman. his wife is still in the hospital, but struggling, now that christina is gone. >> she's a strong woman, and she knows rationally that there's no blame to be apportioned. but the fact of the matter is, she took a little neighbor girl away that morning and was unable

to bring her home. >> reporter: patricia maisch knocked the magazine from the gunman's hand. colonel badger tackled the gunman. >> and yet you're uncomfortable with the idea of having the hero label attached to you? >> this is the hero. if i'm a hero, he's a super hero. >> you gave the shooter a black eye, didn't you? >> he was saying ow, ow, ow, and i, of course, i didn't know roger before this happened, but i said, roger, let up a little bit, and roger said, i don't care. >> reporter: lynn rich, the gunman's neighbor, speaking for the first time. >> i wish that i would have had more courage to have said more to his parents. >> reporter: one of the things that struck me, you spoke of the music. you said there was once beautiful music coming from that house. >> yes, there was. jared played in a jazz band. and i just loved sitting in my house listening to that music

come out of the house. and something changed. >> reporter: and when you asked the family, what was the answer? >> there was no answer. i was just glared at and turned a back on. >> reporter: there were so many in the room who asked, why isn't there more to help detect signs of mental illness long before tragedy? this woman lost her brother, an officer shot and killed, by a man with a history of mental illness. >> i just wonder, how many more of these do i have to attend? we can do better and we can find common ground to stop this from happening. >> the town hall here in tucson. and one more note about that arrest that followed the town hall, we've been reporting on here. james eric fuller, shot twice outside the safeway, he was arrested after authorities say he took a photo of a local tea party official in the audience, telling him, you're dead. tonight, officials say he's been involuntarily committed to receive a psychiatric exam.

that tea party official says this wasn't the only threat he's received. and so i want to bring in rick klein, our washington editor, tonight. i was inside that town hall and i have to tell you, people from all political affiliations had come together for the most part. it wasn't until after the town hall that we saw that flareup. as we look ahead to washington this week, how will politicians stick to policy, keep the fight going and yet change tone as they say they will? >> reporter: that's exactly it, david. the words will change, but the deeds will be exactly the same. republicans jumping right into this in their effort to repeal the obama health care plan. they're going to do so carefully, at least when it comes to the rhetoric. but that will test this truce that seems to have come over washington, to say the least. there's so many high passions around the health care bill. and then you follow that up with next week at the state of the union address. it's going to be an extraordinary scene. there's a mass of lawmakers who say they will sit with a colleague of the opposite party. that will send a powerful signal that while there are deep disagreements between the parties, that doesn't mean you have to be disagreeable about it. >> rick klein, keeping watch there at the white house tonight, rick, thank you. as we reported at the top of the broadcast about that delicate surgery over the

weekend here, doctors carefully removing congresswoman giffords' breathing tube. this will be a crucial week in her recovery. and yunji de nies is at university medical center with more on what the doctors have done this weekend. yunji? >> reporter: good evening, david. the congresswoman is still in intensive care here, though doctors say given she was shot just over a week ago, her progress really has been remarkable. now that that breathing tube is out, the next major milestone will be assessing whether or not she can speak. congresswoman gabrielle giffords is now breathing on her own, without the help of a machine. and doctors have removed the tube that went down her throat. instead, they performed what's called a tracheotomy, inserting a shorter tube directly in her windpipe, below the vocal chords. that will allow her to breathe much more comfortably, and more importantly, will allow her to speak. we do not know yet if she is speaking. >> from a patient's perspective, it's much more comfortable.

therefore, there's less sedation required, if she's more awake, she can participate much more in her own care and physical therapy. >> reporter: doctors also inserted a feeding tube, which is typically routed to the stomach through a small incision in the abdomen. the tracheotomy and feeding tube mean she is still in a very vulnerable state. >> in patients who are critically ill, both of these devices are used frequently, because they are beneficial. they reduce risks to the patient. >> reporter: and doctors say for patients with brain injuries, removing that breathing tube as soon as possible is very important, because our gag reflexes are so strong. any coughing can cause more pressure on the brain, and they said, david, that is the last thing you want. >> all right, yunji de nies at the hospital again tonight for us. yunji, thank you. and we should say that behind the scenes all weekend long here in tucson, diane sawyer has been reporting this story, and this tuesday night at 10:00 p.m. eastern, a one-hour

special. congresswoman giffords' husband, astronaut mark kelly, speaking for the first time. it's a diane sawyer exclusive. tuesday night at 10:00 p.m. eastern. we're going to turn next this evening to the weather, and a pacific storm sweeping through the northwest. flood warnings are posted across western washington and oregon tonight. a number of mudslides have blocked highways and roads. now, to iran this evening, and we're learning more tonight about a secretive effort to damage their nuclear weapons, but not with missiles of bombs, but with a high ly sophisticated computer virus. here's jim sciutto. >> reporter: the announcements came in unusually definitive terms. the normally secretive israeli intelligent chief saying iran would not become a nuclear power until 2015. secretary of state hillary clinton echoing that assessment, saying iran's program had been set back several years. >> iran's had technological problems that have made it slow down its timetable.

>> reporter: many analysts also see is the success of an ambitious u.s. and israeli-led cyber attack. the centerpiece? a computer worm. >> it's really one of the first battles in a new cyber war. >> reporter: in "the new york times," details of a vast program, where the u.s. and israel built centrifuges virtually identical to iran's in this top secret facility in the israeli desert. and then tested the worm that would shut them down. the first step was getting a thumb drive like this, virtually indistinguishable from so many others in common use, into iran and onto an iranian government computer. the virus spreads from computer to computer, but it doesn't do any damage until it reaches the specific computer network it is targeting. in this case, the one running iran's nuclear processing plant. then, it pounces, speeding and slowing the spinning centrifuges so they destroy themselves. and even more impressive, the virus covers its tracks.

the virus secretly records data of the reactor working properly, and plays that back while it is destroying the plant, so operators think everything is okay. success, however, may come with danger. the possibility the virus could be copied and deployed against america's own computer networks. jim sciutto, abc news, washington. >> our thanks to jim tonight. and you might remember the song from the 1970s that said the revolution will not be televised. more modern lyrics might read, the revolution will be tweeted. in fact, the power of social network sites are being credited with the overthrow of a strongman in tunisia. the question now, will this revolution spread? here's alex marquardt tonight. >> reporter: it was an unprecedented revolution that stunned the middle east. in just weeks, the largely young and unemployed tunisian masses overcame bullets, tear gas and beating, toppling a dictator who ruled with an iron fist for 23

years. >> this is the first time in the contemporary arab world that you have a successful popular uprising that has forced the toppling of a regime. >> reporter: they broke through the country's censorship on facebook and twitter, posing videos, rallying others from the region to their cause. "every arab leader is watching tunisia in fear," read one egyptian tweet that shot around the internet. "every arab citizen is watching tunisia in hope and solidarity." the origins of tunisia's protest are simple. high unemployment, high food prices, corruption and lack of freedoms. these are common in countries across the arab world. so, could they leaders suffer the same fate? >> first of all, they're wondering, how did it happen? what went wrong and how do we prevent what went wrong there from occurring in our country? >> reporter: on the list could be some of iraq's most important allies. many egyptians celebrated the news, calling for the ouster of

their president, hosni mubarak, who has been in charge for three decades. in ayman, thousands of jordanians protested high food and fuel prices, and called fur their prime minister to step down. >> we are here to give a message to the government that people will not stay silent. >> reporter: david, people across the middle east have been glued to their tvs and computers for days. memorized by this revolution. tonight, many across the region are asking themselves, can we do that, too? david? >> alex marquardt, thank you. and still ahead as we continue here on "world news" this sunday night, the banks are back. record profits. so, why another number? so many americans out of work for more than 99 weeks now. ronald reagan's sons now feuding tonight, arguing over their father's mind during his presidency. and then later here from tucson, christina-taylor green, the lone girl on the boy's little league team. tonight, the giant words from the stands and the field from some very tiny americans.
