Blunt new warning tonight to iran about nuclear weapons. And abcs chief Global Affairs correspondent Martha Raddatz is in the middle east to tell us what happened tonight and what it means. Martha . Reporter good evening, diane. Sharp words today about what the administration sees as americas two greatest threats iran and syria. Secretary of state john kerry came out blasting today, warning more help for the rebels fighting assad could be coming. But then kerry turned to iran, saying time is running out for a peaceful solution to that Nations Nuclear ambitions. Back home, Vice President biden took a swing, too. Warning military options are not off the table. Big nations cant bluff. And president s of the United States cannot and do not bluff and president barack obama is not bluffing. Reporter why the heat . Remember that red line that israels Prime Minister netanyahu drew, warning that if the world didnt step in by spring or early summer, it would be too late to keep iran from developing a nuclear bomb. Secretary kerry arrives here in qatar soon to drive home that message. We will be sitting down with him tomorrow to talk about these world crises. Diane . And everyone can see that interview tomorrow night, right here. Thank you, martha. And tonight, the world is also watching the cardinals in rome. Who are informally talking about a new pope and deciding when they will begin the secret vote. But it was a surprise to learn today that one person walking among them was a complete imposter. Abcs david wright was there. Reporter the arrivals had the air of the red carpet on oscar night. A glimpse of some of the men who would be pope. But who is that guy . An imposter from a bogus group called corpus dei, tried to gate crash. His cassock and crucifix too short. And on closer inspection, his bishops sash was just a purple scarf. The swiss guard promptly showed him out. The cardinals are electing an absolute monarch, in a process where the candidates and the voters can easily fit into one room. To foster a frank conversation, they swore an oath of secrecy. Do these guys, certainly they know of each other, but do they know each other well . By language groups and geography, those ones know each other well. Globally, no. Do all the 115 voters know each other well . No. Reporter as of tonight, about eight voting cardinals have yet to arrive. Only when theyre here will they set a date for the conclave. Today, the papal tailor changed his shop window. Now available . Ready to wear cassocks in three possible sizes. The color . Papal white. David wright, abc news, rome. And now, back here at home, we have the first images from florida of that cavernous sinkhole that swallowed a home and a young man in his bedroom. And abcs gio benitez is there. Reporter this is our first look at the massive sinkhole that swallowed up 37yearold jeff bush while sleeping in his bed. Look closer. Authorities tell abc news, the sinkhole, about 30 feet wide and 100 feet deep, could well extend underneath the two neighboring homes. Both less than 40 feet away. There is no one allowed in those homes and there will be a determination made if they are condemned in the coming weeks. Reporter earlier today, crews used heavy machinery to recover some of bushs personal items from the bedroom, carefully collecting his jacket and hat from the wall. But jeremy bush is frustrated his brother remains buried in the rubble. They got this Big Equipment and why cant somebody be hairnessed up in that equipment and try to rescue him . Reporter Authorities Say thats just too dangerous. Any additional loss of life would have made this tragedy even worse. Reporter so, today, that machine ending the demolition by sending flowers for mr. Bush down into what is now his grave. As crews now fill this sinkhole with gravel to stabilize it, weve learned a new sinkhole opened up just hours ago here in the same town. This one, were told, did not hurt anyone. Diane . All right, gio, thank you. And we know some of the neighbors near that sinkhole where you are have not been allowed back in their homes, either. And tonight, there is a story that has created a lot of hope about aids. And all the babies born with hiv around the world. Doctors say a baby born in mississippi two and a half years ago to an infected mother is now completely free of hiv. They say that 30 hours after this baby was born, they gave her a strong dose of three drugs, not the usual dose of one or two drugs. They believe this big dose knocked out the virus before it could set itself up in her body, so, the next step is to see if it can happen again with another baby. A reminder, every year, there are 300,000 babies around the world born with hiv. And now, to another medical story making headlines tonight. You have heard the 911 calls, an employee at a Retirement Community refusing the plea of a 911 operator to give cpr to an elderly woman who had collapsed. What happened has raised Big Questions about what is right and what is legal. Heres abcs dan harris with some answers. Shes possibly not breathing, okay . Reporter we heard the tape, the desperate 911 dispatcher, trying to convince an employee at this independent living facility to give cpr to 87yearold Lorraine Bayless who had collapsed on the floor. We need to get cpr started. Yeah, we cant do cpr. Are we just going to let this lady die . Well, thats why were calling 911. We cant wait. She cant wait right now. Reporter the passion of the dispatcher and passivity of the employee have created outrage and this question isnt the facility obligated to help . The worker and her boss say no, that this is not a nursing home, but an independent living facility, which, by law, is not licensed to provide medical care. While local police said today they are investigating whether there was any criminal wrongdoing in this case, experts say what happened here was legal. Believe it or not, we dont have to be a good samaritan. Morally, we should be. Reporter back on the 911 call, as bayless continues to lie dying on the floor, the dispatcher tries a different tactic. Is there anybody there thats willing to help this lady and not let her die . Not at this time. Reporter so, the second question. If a stranger had jumped in, could they have been sued . The answer improbable. Most states have laws protecting good samaritans. Lorraine bayless ended up dying in the hospital. But there is this to keep in mind the statistics are as low as 3 , just 3 out of 100 people would survive. You know, cpr, when done properly, does often result in broken ribs, so, it can be very traumatic. Reporter tonight, doctors tell us, just because the odds of success are low, that doesnt mean you dont try to save a dying woman. Dan harris, abc news, new york. And now, we turn to another story, were back in washington, on the first full day after the 85 billion in budget cuts kicked in. Some members of congress have said its time for all of us to tighten our belts. But Abcs David Kerley has been on the lookout. Tonight, its our washington watchdog. Reporter they are iconic. Washington, jefferson, franklin. Oil on canvas portraits. But ed schafer . Remember him . The 29th agriculture secretary . Well, you paid for his painting. The latest for lisa jackson, the outgoing epa administrator. A 38,000 portrait. Thats just ten grand less than what the average american makes in an entire year. How about 41,000 for the air force secretary . And 22,000 for a commerce secretary who served president obama for only eight months. We found, in the past two years alone, almost 400,000 spent on portraits. We wanted to show you some of those portraits that you paid for. But the white house wouldnt allow our camera to go into any federal buildings to see those paintings. Surprisingly, some of the Oil Portraits are commissioned while secretaries are still serving. 22,000 for agriculture secretary tom vilsack, who we tracked down to ask is it time that we stop doing Oil Portraits of former secretaries . You know there are so many questions id be happy to answer about our budget. I just think thats a really small ball kind of question. Reporter small ball . It just shows how washington has just become immune to the cost of things. 20,000 on a portrait . Thats real money and thats real waste. Reporter today, the white house told us theyre spending less on portraits than previous administrations. But what about saving even more . A 21st century alternative. Digital photographs printed on canvas. We took a shot and then we went to our local costco. A week later, for less bucks oh, not bad. David kerley, abc news, washington.
