And for the latest on who was shooting and how many were killed, abcs david wright has these breaking details right now. David . Reporter good evening, diane. This is, as you say, a developing story, but heres what we know so far. At least one person killed, possibly more. Others injured, in a mall shooting, a shooting that apparently broke out near the food court of the clackamas town center. Police say the gunman has been neutralized. Unclear if that means hes in custody or dead. Just before 3 30 this afternoon when shoppers heard shots run out and people started running. I got there two minutes early. I walked through the food court. Went downstairs for my kiosk, which is right below the food court. When i got there, i was talking to my employee. We heard a bang. We covered our ears and we got down. In a matter of five seconds later, we heard rapid fire, bang, bang, and i just took off running. I dont know where my employee is. I heard shes still inside the mall. Reporter witnesses described a man what an automatic weapon wearing camouflage ed clothing. Many were on the phone with abcs affiliate k2 in portland, locked inside the mall, describing the terrible skeent of events as it unfolded. One said the mall santa claus dropped to his knees to avoid the gun fire. We actually are currently locked inside of a store in the mall with about ten people. And s. W. A. T. Teams are going around the mall, trying to apprehend the suspect. I saw two. Two people shot . Uhhuh. How serious . We had to bring sheets out of our back room for them. So, it didnt look like they made it . No. One shopper tweeted out this photo from inside a locked store. Police say the gunman has been neutralized, but they are taking precautions, going store to store to see if anyone may still be trapped inside or if there may be any accomplices. At this point, this is no longer an active shooter. We believe the shooter has been neutralized and we are securing the mall, the scene, and treating the wounded. Reporter police say the crime scene has calmed down considerably but no indication yet who this gunman might be or what his possible motives might be or even his m. O. Was he shooting randomly or at targeted individuals . One thing to underscore here, though, this is the Holiday Shopping season across the country and this is sure to send shock waves across america as people absorb yet another shooting rampage. Diane . Thank you, david. And i know youll be tracking the developments tlou s through night on this story. But we move next here to an abc news exclusive. The president sat down with abcs Barbara Walters at the white house this afternoon. And he said something about syria that signals a whole new day for the u. S. Barbara walters is here right now with what happened at the white house today. Barbara . Reporter just a year ago this month, i met with president assad in damascus and i questioned him about the slaughter of his people. Since then, 40,000 people have been killed. Well, today, president obama had some big news. For the first time, he is putting the Syrian Opposition on the path to be recognized as the new government if and when assad falls. Id like to talk about syria. Do you plan to recognize the opposition and give them some legitimacy . Weve made a decision that the Syrian Opposition coalition is now inclusive enough, is reflective and representative enough of the syrian population, that we consider them the legitimate representative of the syrian people, in opposition to the assad regime, and so we will provide them recognition and obviously with that recognition comes the responsibilities on the part of that coalition. Reporter thats a big step. It is a big step. There is a small element of those who oppose the assad regime that are, in fact, affiliated with al qaeda in iraq. And we have designated them, al nusra, as a terrorist organization. And we are going to make clear to distinguish between those elements of the opposition. Reporter for the president , recognizing the Syrian Opposition as the legitimate authority in that country, many are asking what this may mean in terms of u. S. Involvement. But today, a Senior Administration official said that there is still no plan to arm this group. Yet, the government hasnt ruled it out. Meanwhile, the other issue on the forefront of the president s mind today the u. S. Economy and that pending fiscal cliff. Are we going to go over the fiscal cliff . You know, i remain optimistic that there are enough people of good will in this town that recognize our economy will be much better off, American Families will be much better off, if we get this done. The most important thing we can do is make sure the middle class taxes do not go up january 1st and im pretty confident that republicans would not hold middle class taxes hostage to try to protect tax cuts for high income individuals. Reporter prediction. Are you going to be able to raise taxes . Yes or no . Oh, taxes are going to go up one way or the other. Reporter oh, they are . And i think the key is to make sure the taxes go up on high end individuals like you and me, barbara. We can afford it. It is entirely possible for us to come up with a deal. But time is running short. Reporter the president sounded optimistic about avoiding the fiscal cliff. He said, of his meeting with Speaker Boehner, i think the tone was good. I believe both Speaker Boehner and myself and the other leaders want to see a deal happen. But diane, he did warn that the clock is ticking. It is for sure. And i know youre going to have more of this interview, well all be watching, tomorrow morning on gma, tonight on nightline and the full interview with the president and with mrs. Obama will be airing on a special edition of 20 20 on friday night. And, by the way, on that question of the fiscal cliff, i had an extraordinary conversation today in washington, as well. With a group of people who are making history. It has taken 224 years, but for the first time, a record 20 women will be serving in the United States senate. And today, many of them gathered with me and some of them said women do lead in a different way. And women would have already brokered that deal on the fiscal cliff. I think, if we were in charge of the senate, and of the administration, that we would have a budget deal by now. Reporter do you all believe that . Yes, without a doubt. Yes. And what i find, with all due deference to our male colleagues, that womens style tend to be more collaborative. I think by nature we are less confrontational and more collaborative. And having us in the room and, i think, you know, all of us, not only do we want to work in a bipartisan way, we do it. I want you to know that soon, youll see the whole interview with the powerhouse women of the senate. They are here to take action. And you have to see what theyre going to be saying. And now, we turn to that showdown raging in the heartland of the United States. Perhaps no place in america more closely associated with unions than the state of michigan. And today, thousands of Union Workers descended on the capital to protest a new law they believe could be an ominous signal for unions and worker paychecks everywhere. Heres abcs alex perez. Reporter the anger boiling over. Officers turning to pepper spray to control the crowd at least 10,000 deep. But it wasnt enough. Michigan republican lawmakers approving landmark legislation, lifting the requirement that workers in unionized workplaces pay union dues. An army of officers have been guarding the Governors Office all day. Some of these demonstrators have been here since 5 00 this morning. The republican governor has signed the law. With a stroke of a pen, take our rights away. Its offensive. Reporter supporters call it right to work, but unions say its nothing less than an effort to cut their bargaining power. Less dues means less influence. The aflcio says the average worker in right to work states earns 1,500 less than workers in states without those laws. These socalled right to work laws, they dont have to do with economics, they have everything to do with politics. What theyre really talking about is giving you the right to work for less money. Reporter but supporters say the law encourages business. Chris beckering owns a Construction Company and predicts the bill will allow his company to hire more workers. This will attract more businesses to michigan. Those businesses will need space and were here to build it for them. Reporter whats remarkable about what happened today is that it happened in michigan, the heart of union country. Home of the united auto workers. Now michigan will become the 24th right to work state. Alex perez, abc news, lansing, michigan. And we have another milestone tonight for american taxpayers. Perhaps the most infamous bailout of the whole financial collapse was the rescue of Corporate Giant aig. Taxpayers, you may remember, poured 182 billion into the company to keep it afloat. But today, the u. S. Treasury sold its last share of aig stock. And it turns out, taxpayers made a profit of 22. 7 billion. And today, that good news sent a jolt across wall street. The dow closing up, the fifth straight day of gains. The longest rally since march. We want to show you an image that came into our news room today. Imagine seeing this through your front windshield. It was the scene on an interstate highway in West Virginia today. A massive gas line explosion, flames 75 feet high. So intense firefighters couldnt even approach. Eye witnesses say it sounded like a boeing 757. The fire raging for an hour, completely destroying four homes, damaging five others and leaving two people with minor injuries. And now, a major headline for the millions of americans battling depression. 1 in 10 americans take antidepressants, but they can take weeks or months to bring relief. Well, now, the National Institutes of health is saying theyre trying a new kind of medication that may bring relief much faster. Abcs chief medical editor dr. Richard besser tells us more. Reporter a lifetime of depression lifting in just a few minutes. Dennis, suffering for years, had tried pretty much every antidepressant on the market. No response. They never helped me at all. Reporter but at the National Institutes for health, theyre trying out a whole new class of antidepressants. Drugs that may offer a new path to fighting depression, fast. A couple hours . Yes, thats all it takes, instead of a couple weeks, we can achieve the same thing in a few hours. Reporter typical antidepressants target the serotonin in your brain, a chemical that controls happiness. But you cant tell if the drug is working for four to six weeks. But this new drug is working in a completely different way, targeting the glutamate system, working on neurons that control mood. They seem to show results within hours. For dennis, its meant a glimpse of a whole new life. I c get up in the morning, i can return calls, i can do the things that people do without impairment. It doesnt feel like i have to fight in order to do those routine tasks. Reporter dr. Rich 5rd besser, abc news, washington. Now, i want to bring everyone up to date on the former president of south africa, the man who ended about p apartheid, nelson mandela. The 94yearold has been in the hospital since saturday, and until now, we didnt know why. But today, we learned that mandela is receiving treatment for a lung infection. He is said to be responding to treatment tonight and while we await his release, we thought back to that other image, the man who walked free after 27 years in prison.

A manhunt is under way tonight for a gunman who struck in broad daylight, in the middle of a crowded street. A young man killed, execution style. Here with the new images, abcs john schriffen. Reporter this is the chilling image just moments before police say a suspected hit man pulled a gun from his pocket and put a bullet into the back of the head of 31yearold Brandon Lincoln woodard, a father and aspiring lawyer from los angeles. Police are now looking for this man, who somehow managed to slip away, with more than a dozen witnesses nearby in manhattans columbus circle. Heres how the calculated murder went down. Police say around 1 20 monday afternoon, the suspect arrived at the scene waiting for his victim. 30 minutes later, he gets out of the tan getaway car, talks to his getaway driver and scopes out the scene. Watch as multiple people walk by, getting a glimpse of the killer before he pulls his hood up, then begins pacing up and down the block, even passing by his target. Minutes later, as woodard walks down this busy street with surveillance cameras catching his every move, the suspect walking up from behind. Police say thats when the victim looks up from his phone, instinctively turns around, but decides to keep going. Seconds later, around 2 00, thats when police say the suspect pulled out a silver semiautomatic pistol, firing the fatal shot. The hit man then calmly gets into the passenger side of the getaway car and takes off. Nobody saw him. There were 50 people at least on that corner, nobody seen the guy. Reporter abc news has learned woodard had more than a dozen arrests dating back to 2004. But police say they still dont know why someone wanted him dead. John schriffen, abc news, new york.
