captions paid for by abc, inc. good evening. president obama is heading into a very big week on two iues that may well define his presidency. tomorrow, it's the economy. mr. obama hes to the scene of the crime, wall street, where he'll give a speech on the first anniversary of the collapse of lehman brothers, which many believe triggered the financial crisis. on thursday, it's health care. reheads to maryland for another rally to push his controversial reform plan. today, more cracks were developing in a central pillar of that plan. here's david kerley. >> reporter: the president is regaining a bit of momentum in the health care debate, according to polling. >> hello, minneapolis. >> reporter: progress he's trying to capitalize on, looking like a campaigner. >> i will not sign a plan that adds one dime to our deficits. either now or in the future.

>> reporter: but this weekend showed the divide in the health care debate looms large. at least 60,000 people marched on the capital, blaming mr. obama is trying to charge too much too fast. >> this is ridiculous. health care, everything. it's ridiculous. >> it's not just one thing. it's a bunch of things. >> reporter: today, the president's caor f a porublic option received another nail in the coffin, from the very republican senator considered essential to pass health care reform. >> i urge him to take it off the table there's no way to pass a plan that includes the public option. >> reporter: while refusing to call the option dead, even the president's men -- >> he refers the option. >> reporter: today downplayed the necessity. >> we should not let it devolve into this one question. >> reporter: tonight, it appears the senate bill will include insurance co-ops, nonprofit organizations owned by the very people they insure. the white house is well aware

that the president's entire agenda could be at risk in this debate. something mr. obama acknowledges tonight in a "60 minutes" interview. >> i own it. if people look and say, you know what, this hasn't reduced my costs, my premiums are still going up 25%, insurance companies are still jerking me around, i'm the one who is going to be held responsible. >> reporter: the nearly trillion dollar cost of this plan continues to be the center of the debate. mr. obama plans another rally on could be that all-important senate plan. the gang of six, as they are known, three republicans and three democrats, are said to be very, very close to their version of health care reform. dan? >> as we said, another big week. david kerley in washgton, thank you. the congressman who interrupted the president's health care speech to congress the other day, yelling "you lie" says he is done apologizing. the house speaker has told joe wilson that he must publicly apologize to congress from the house floor. today, however, the republican

from south carolina said that is not going to happen. >> i am not going to apologize again. i apologized to the president on wednesday night. i was advised then that, thank you, now, let's go to a civil discussion of issues. >> house leaders plan to propose a resolution of disapproval this week if wilson does not publicly apologize to congress. the president heads to wall streetomw torro afor a speech hers c.n brheotrs.ofor cheollap he white house says t president will point out that the economy is now improving, but he will also argue that there needs to be tougher regulation to prevent another collapse. in a moment, we're going to talk abt what, if anything, has been done on that front, but first, a quick look at how our world has changed in the year since lehman went down. one year ago, this weekend, government officials were huddling, trying to decide whether to rescue lehman brothers, a bank previously considered unsinkable. the government decided to let lehman collapse, and that

triggered what is being called the great recession. since then, the economy hashed nearly 6 million jobs, and the value of the average existing home has decreased by about 15%. though many economists say it would have been even worse without the $700 billion bailout of wall street's other major banks. stocks, too, took a nose dive after lehman collapsed, dropping almost 5,000 points at the bottom, but today, they're on a rebound, though still 1800 points lower than they were a year ago. americans have started cautiously to peer at their 401(k) statements once again. >> since the bottom six months ago, everyone should be feeling a lot better about their nest eggs. >> reporter: if you're more than ten years away from retirement, many analysts say it is time to start taking some risks in your retirement account again, including stocks. but what about wall street itself? what has been done to prevent a repeat of this crisis?

>> policy makers have done a lot of good work stabilizing the financial system, but they've not changed anything fundamentally. until they do, the risk of another financial pan nick our future is still very high. >> so, we have with us tonight our business correspondent bianna golodryga, thank you for coming in. what, if anything, has the government really done? >> reporter: a lot of people would be surprised at the lack of change we've seen on wall street. yes, lehman is gone, 8% of the work force is gone, but the banks that have survived are doing better than most have expected by now. they are definitely back in the green. and it's a lot harder to put together any sort of regulatory change or reform when you're seeing banks make profits. and as rahm emanuel is famous for saying, never let a major crisis go to waste. it's tougher to let a crisis really result in any change when banks are coming back. >> when the crisis is resolving. what about the culture on wall street? are people chasing one year after, they have stopped taking

on excessive risk? >> reporter: here's the thing. somebody told me the other day they were surprised, because back then the major issue is, if you are looking at the corporate profits we've seen, wall street took about 30% of that, guess what today, it's still at 30%. a lot of the payackages are tied to stock performance. if stocks are doing well, it's difficult for companies to say, you know what, we have to mine miss your pay. >> doesn't sound like much change. bianna, thank you. and we will continue our reporting throughout this week here on "world news," and a special series examining where things really stand with the economy one year after the collapse. there is a major shift to report tonight at one of the u.s. military's most notorious prisons, the one at the bag ram air base in afghanistan. for the first time, inmates there are going to be allowed to challenge their custody. clarissa ward is in afghanistan tonight. >> reporter: this is the airfield at bagram air base. the closest you're likely to ever get to the ison. the detension facility is kept

completely secret. located just 35 miles north of kaubl, there are approximately 600 detainees at bagram, some who have been held without charge or trial for six years. these men were all held at the prison and claimed to have suffered beatings, sleep deprivation and threats to their lives. "they put a pistol in my ear. they said i had to speak or be shot," this man said. like abu ghraib and guantanamo bay, for many afghans, bagram has become known for horror stories. up nm now, the obama administration has argued that the prisoners at bagram are terrorists suspects and enemy combatants. >> they do not have any access to u.s. courts. they do not have access to their attorneys and theyisave no e stithe i tirnnocence.n >> reporte bnduthe u ter new initiative, ch detainee would be assigned a military-appointed

representative. the new policy is unlikely to change public support for a war which has grown uncreasingly unpopular after eight years. as congress awaits recommendations from the top military commander in afghanistan, more and more democratic leaders are speaking out against more troops. >> the larger our own military footprint the, the more our enemies can seek to drive a wedge between us and the afghan population. >> reporter: and dan, an interesting note. a recent military investigation found that the vast majority of detainees at bagram has never before engaged in hostile action with u.s. troops. dan? >> clarissa ward in afghanistan, thank you. and also in afghanistan, three american troops were killed when their convoy was mbushed in a region tha tt is controlled by militants.s. u.orceu.s launched a furious counter attack that lasted for more than six hours, and killed as many as 50 enemy fighters. and, the iraqi journalist who threw his shoes at then-president bush is spending

his last night in prison, after serving eight months of a three-year sentence. he has reportedly been offered cash, jobs, and even a wife from people who appreciate his defiant act, which was cheered across the arab world, but embarrassed iraq's government. back in this country, today was supposed to be wedding day for annie le, who disappeared sharyn alfonsi has the latest on the search for her. >> reporter: on the day le was supposed to get married, cadaver-sniffing dogs search a waste processing facility in hartford, looking for clues about her disappearance. earlier this weekend, sources say investigators found bloody clothing hidden above the ceiling tiles in the yale lab where le was last seen. >> i'm not going to get into the specifics. the items seized are being examined to determine if there's any association to le.

>> reporter: le was last seen in this video, walking into the lab at 10:00 on tuesday morning. but there are no signs of her walking out. so, today, investigators are reviewing tape from more than 70 cameras like thione, looking for clues. le's family admits they are nervous. >> i feel lost. i don't know what happened to my niece. >> reporter: le's family was accept posed to be celebrate her wedding today on long island. but outside the home of her fiance, wedding gifts wait at the doorstep, and at a nearby florist, they hope for the best. >> this was annie's bouquet. we hope she's found safe. >> reporter: the mystery of le's disappearance reminds someone of another dark chapter in yale history. in '98, a yale student was found stabbed to death in new haven. that crime remains unsolved. investigators don't believe there is any connection between the two cases, but as the days pass, concern on campus deepens. >> we haven't heard anything,

really, and i just want her to be okay. >> reporter: sharon yn alfonsi,c news, new haven, connecticut. and american scientist credited with helping to save more than a billion lives from famine has died. norman borlaug, the father of the so-called green revolution, won the nobel prize for creating a system of crop management that increased harvest. he was 95. and coming up here on "world news" this sunday, are laptops and ipods making books ancient history? we're going to take you inside the changing american classroom. one of the world's most sophisticated anti-terror units, the police department with more arabic speakers than the fbi and cia combined. and, serena williams making a racket at the u.s. open. was her on-court outburst over the line? i never thought it could happen to me... a heart attack at 53.
