corporate funding is provided by mutual of america-- designing customized individual and group retirement products. that's why we are your retirement company. additional support is provided by: and by the corporation for public broadcasting and by contributions to your pbs station from viewers like you. thank you. from the tisch wnet studios in lincoln center in new york hari sreenivasan. >> thanks for joining us. the fight over funding for the department of homeland security starts all over again on capitol hill tomorrow. congress has given itself until midnight friday to come up with some kind of agreement. but the rift among republicans continues to endanger any deal. a contingent of house republicans is refusing to fund the agency unless the bill moves toward blocking the president's immigration reform plan.

the intra-party division puts house speaker john boehner in a tough position: side with house moderates and senate republicans to fund the agency, or side with more conservative members to challenge the immigration policy. but this morning boehner told“ face the nation” his party is united in its goal to stand up to president obama. >> i made it clear we're going to do everything we could to block the president's executive over-reach, and that's the basis of the problem we're trying to deal with. >> sreenivasan: democrats still hope to vote on a long-term funding bill without ties to immigration. >> we want a clean bill. we have past taken votes on a clean bill, it's well known. and i see nothing else happening, other than a clean bill. >> sreenivasan: israeli prime minister benjamin netanyahu left for the united states this morning, preparing for his controversial appearance before congress on tuesday. house speaker boehner invited netanyahu to speak, and this

morning, secretary of state john kerry called it odd that the administration wasn't included in the process. but he told abc's “this week” the white house doesn't want to turn the visit into a “political football”. >> the prime minister of israel is welcome to speak in the united states. obviously we have a closer relationship with israel right now in terms of security than in any time in history. >> sreenivasan: tens of thousands of russians marched through the streets of moscow today, mourning the death of one of president vladimir putin's most vocal critics. opposition leader boris nemtsov was gunned down just outside the kremlin friday night. today mourners passed through metal detectors, then marched near the crime scene amid a massive police presence. russian officials are investigating several motives including whether nemtsov was assassinated because of his criticism of president vladimir putin. doctors in sierra leone are reeling from a new wave of ebola victims. sierra leone had seen a drop in cases and even planned to lift travel restrictions and re-open schools.

but last month, sick fishermen returned to shore, setting off a new series of 21-day quarantines. the country's own vice president has quarantined himself after one of his security guards died of the disease. here in the u.s., ebola survivor, nurse nina pham, plans to sue the texas hospital where she contracted the disease. attorneys claim the hospital didn't properly train the staff to deal with the outbreak. european counter-terrorism investigators believe at least sixty british women and schoolgirls may have traveled to syria to join isis. five of them are reportedly 15 or 16 years old. three of those british teens were spotted on security video while travelling in turkey last month. turkish police are searching for the girls, but investigators fear they've already crossed the border into syria. we'll have more on the fight against isis here in the united states in a moment. a new report from the united nations says at least 1,100 iraqis were killed in february. more than 600 of them were civilians. the u.n. blames isis and is

calling on fractured iraqi leaders to join forces to fight back. but there's also some good news out of baghdad tonight-- iraq's national museum has officially re-opened, 12 years after it was vandalized in the aftermath of the u.s.-led invasion. looters stole the museum's antiquities during the fighting, but many of the objects have been found and returned. the opening comes just after isis released video of militants destroying statues in mosul. hyundai is recalling almost 205,000 cars because the power steering could suddenly stop working. the recall covers the 2008-to- 2010 elantra and the 2009-to- 2010 elantra touring. hyundai did not mention any accidents or injuries related to the steering problem. you can find the specific cars getting recalled on our website at pbs.org/newshour.

>> sreenivasan: federal investigators believe they've managed to capture three suspected isis sympathizers before they launched an attack. on wednesday, u.s. law enforcement charged three brooklyn men with providing material support to a foreign terrorist organization. two of the suspects allegedly planned to travel thousands of miles to fight under the flag of the islamic state. if that didn't work, they threatened to carry out attacks in the united states. new york city police commissioner william bratton characterized the arrests saying, “this is real. this is the concern about the lone wolf.” we are joined now from washington, d.c. by andrew grossman who has been covering this story for the wall street journal. test so andrew, how did these arrests go down, what kind of tools did they use to get them. >> what we saw here was a fairly common pattern that law enforcementment in. u.s. has been using against people who might be plotting to catch isis or other foreign terrorist groups. they first attracted authorities attention on-line with a post on an uzbek language web site about threatening to kill the president. that got the attention of

the secret service. other law enforcement in new york and they began to keep an eye on these guys eventually put them in touch with an informant without worked with them sort of s, ssed out what their intentions were, as they got closer and closer, at one point one of these men was going to go get on a plane at j-- jfk that is when they came and made the arrests. >> what about the possibility that they didn't make a threat to the life of the president that they could have gone undetected all together. >> that's the big worry here. i think the proliferation of on-line propaganda is really a double eqed sword here. it's luring people like this into-- it gets them interested if going to join one of these groups. but on the other hand authorities can see a lot of that traffic. they can see when people are getting in touch with someone overseas who might want to help them travel. so you know it is -- that is the big worry is these lone wolves as opposed to known wolves as law enforcement started calling

them. the known wolves, at least they can see and keep an eye on. the lone wolfs who might be radicallized about the propaganda and carry out an attack here are the big worry for law enforcement. >> srennivasan: there's also concerned that the known wolves list is so large that we just don't have the bodies to keep up and do surveillance on all these potential threats. >> right. i think it's hundreds of thousands on the u.s.'s terrorist list alone. and the fear also is, you know the u.s. has about 150 people who have attempted to travel or traveled it to fight in syria, not all for isis but for various groups there. the europeans, for werners it's about 3400 and now that's a worry for law enforcement because a lot of those people are from countries that have visa waivers that can easily come to the u.s. or they can carry out attacks in europe is so it's a much bigger problem for law enforcement and allied countries as we saw in france not too long ago.

>> srennivasan: is this a shift in law enforcement approach. we were talking in the newsroom this morning t almost seems like the precrime division from the movie "minority report" trying to figure out, before you commit a crime, stopping you. >> this has actually been somewhat controversy. this use of informants. the fbi has been doing this to some degree since not long after september 11th. a lot of these cases, you know, there have been cases where an informant or an undercover fbi op rattive gets in touch with someone who appears to be interested in doing carrying out some sort of attack. and really walks them through the steps necessary to get them to the point where they're almost in certain cases have their hand on the trigger of what they think is a bomb, as we saw, for example in a case in chicago. and once they go push that trigger it turns out that the whole thing is a settup. and you know, some of that has been controversial. the fbi says they really try to stay-- they do stay on the side of letting the target the suspect drive

the operation. but you know it's a very close fine line between that and entrapment. >> all right andrew grossman from "the wall street journal," joining us from washington thanks so much. >> thanks, hari. >> sreenivasan: we turn now to our signature segment. thieves have been hitting states from california to pennsylvania stealing metal. it's a national problem that's become an increasing threat to public safety. the thefts have caused blackouts and traffic accidents. in this updated segment that originally aired in july newshour correspondent rick karr traveled to ohio where a new state law aims to tackle the problem and prevent the thieves from cashing in. >> reporter: angela day's landline kept going dead in 2012. she didn't have a cell phone she could use instead because cell coverage is spotty in the appalachian region of ohio where she lives.

and at the house where she was living with her daughter and her parents, there's no cell signal at all. so whenever she had to be away from home, she worried especially about her father. >> he had a heart condition, and he had had several open-heart surgeries. he had triple-bypass surgery. >> reporter: a few days after christmas, he said he wasn't feeling well. >> he called over to talk to a nurse, and he was having problems with the phone. >> reporter: his condition deteriorated, and finally he said he needed an ambulance. the family called 9-1-1, but the line was so bad that they finally gave up and day's brother rushed their father to doctors. but it was too late. he died that evening. >> it was really frustrating close to the whole week afterwards we couldn't even call out to plan the funeral. we couldn't even call and tell family that he had passed. i had to go to my workplace to use the phone to even call the funeral home. >> reporter: angela day's phone didn't work because thieves were stealing telephone wires all over the county.

it's one of the poorest in ohio, and the copper in the lines was valuable. there could be hundreds of dollars worth in the cables strung between two utility poles. at the time, thieves were stealing all kinds of metal throughout ohio: parts from farm equipment and electrical substations, manhole covers, grave markers. for five years running, the state has led the nation in metal thefts. and from one corner of ohio to another, thieves have put the public in danger. according to police here in akron, there was an accident on that interstate highway behind me because of an attempt to steal copper wire from the high tension lines beyond it. the would-be-thieves climbed up and cut the line so it dangled over the interstate under thousands of volts of tension. when an s.u.v. got too close, there was a bright flash that blew out the windshield and knocked the driver unconscious. the driver survived, but thieves themselves aren't always so lucky.

i'm struck by the idea of somebody climbing up a utility pole and cutting something like this down. i mean this is going to be carrying a lot of juice. this is going to be a dangerous crime to commit. >> let me be very clear on this. we have people dying regularly for this. >> reporter: commander bob meader's been dealing with metal theft for more than two decades as a columbus cop. metal prices have come down recently, but copper is still more than twice as valuable as it was a decade ago. in 2007, columbus became the first city in the state to crack down on metal theft. police couldn't keep an eye on every piece of metal thieves might steal. but the city could make it harder for them to sell it. >> we know that it's not going to go to the center of the city and put a sign out and say, "i have scrap metal for sale." there's one location in the state of ohio, and throughout the united states, that they can get money for it, and that is a scrap yard. >> reporter: columbus enacted a new ordinance requiring scrap

yards to follow rules a lot like the ones that apply to the city's pawn shops. scrap dealers have to check every customer's i.d. against an online database of convicted thieves, who might be trying to sell what they've stolen. dealers have to record every detail of every purchase they make so that law enforcement can investigate thefts. columbus officials say those steps are helping to reduce metal thefts. last month, there were only 57 thefts reported in the city, compared to more than 100 a year ago. ohio legislators decided to implement what columbus did statewide. the new law fully kicked in last month. now, more than 400 scrap yards from cleveland to cincinnati to toledo are required to record every customer's information in a law enforcement database, and check to see if their names are on a list of more than a quarter million conviction records. ohio scrap dealer josh joseph

says when columbus cracked down, thieves went to scrap yards outside the city limits. now that the whole state is cracking down, they'll just go to scrap yards across the state line. >> for someone to steal it, drive someplace where they know there are really laxed laws or laxed enforcement of the laws, and sell it, is a really easy thing to happen. the uniformity of the law, the uniformity of the way that it is enforced from an industry perspective, we see as paramount to the success of the law. >> reporter: joseph has a lot of other concerns about the law. for one thing, he worries about what the cost of complying with it will do to family-owned small businesses in the industry. >> it's anywhere from probably $20,000 or $30,000 up to hundreds of thousands of dollars. you know, we've spent six figures to, to maintain upgrade, and train our people in order to be compliant. >> reporter: and training might not be enough to keep some employees honest. how can you be sure that if

somebody steals, say, a bunch of copper wire, brings it in, slips one of your employees $100 bucks, how do you ensure that your employee's not susceptible to that? >> i would say that our employees are susceptible to that. we think we've had some instances of that happening in the past. >> reporter: have you ever had to fire anybody? >> we have. >> reporter: there could also be consequences to the environment, according to scrap dealers. they're in the recycling business. the metal they take in gets melted down and reused. the law in ohio makes it a crime for scrap dealers to buy certain items unless sellers can prove something's theirs to sell electrical lines, for instance, and telephone cables. but the list also includes items homeowners might bring in. and that could end up in a landfill if a scrap dealer refuses it to stay on the safe side of the law, according to robin weiner, who runs the scrap industry's washington-based trade group. >> i've gotten e-mails from citizens who've complained that

they've gone to one of our members and the members, and then the member asked for proof of ownership and they don't have that. you know, how are they going to they want to do the right thing and recycle. >> reporter: josh joseph's family's been in the scrap business for four generations. he doesn't like his business being compared to a pawn shop. and he's not sure his industry should have to bear the burden of cracking down on metal thieves. thieves will keep stealing metal, according to angela day, as long as it's valuable. a couple of months after her father died, police arrested two men who were charged with stealing phone lines, including the one that law enforcement officials say affected the call to 9-1-1 the day her father died. she'd known one of the men as a kid. and she understands what motivated the crimes. >> growing up here you realize how desperate people are and how much in need this area is. i mean, there's not a lot of resources. they're still going to be stealing things. i mean, that's just a part of life. i don't care where you live in the united states.

you're going to have that. you're going to have people desperate or stealing, to make you know, to survive. >> reporter: both men are serving prison terms for stealing the telephone lines. >> sreenivasan: how much can you legally make scrapping metal? visit pbs.org/newshour for answers. some cutting-edge research is giving new hope to cancer patients. researchers are zeroing in on the causes of specific cancers and are finding dramatically different ways to fight the disease. to explain the latest findings, i'm joined by dr. david hyman, an oncologist with memorial sloan kettering cancer center. so as we talk about cancer, as we talk about hope let's just kind of clarify, what is the current way we treat cancers and what are some of these new studies showing? >>. >> the historic ways that we've always treated cancers is treating them based on the organ they come from. so treating patients with breast cancer or colon cancer or lung cancer eye dent-- eye dentically am

what these are asking is whether we can target specific mutations which are mystics in the genes that arise in tumors and treat them the same even if they come from different organs. so we recognize that there are certain mutations that we find-- we find across multiple disease types. and so one question is can we really start to think about these diseases as diseases harboring mutation a or b rather than lung cancers or colon cancers. >> and so how effective are these drugs when they target a specific mutation instead of a specific region of the body that the cancer is coming from? >> they can be very dramatically effective in ways that are really previously unprecedented. so we know for example in lung cancers chemotherapy has a response rated best in ot 30% range. we have certain medicines now that target certain mutations in lung cancer where the majority of patients have benefitted and their tumors shrink. so what we are trying to do is take those early

successes in lung cancer melanoma and now extend those to the larger variety of cancers that we see. >> so how much of the sea change is this? i mean when you think b as we began this conversation in my own head i was thinking lung cancer breast cancer colon cancer just like you said. now are you talking about a completely different approach to even looking at and learning these cancers and saying here is what makes you you. >> here is what makes this cancer quick or grow. it's a really big change in the way that we think about cancer. it really is this idea of precision pledz, you know not treating all patients the same but treating their individual cancers based on really detailed analysis. and i think it really represents a sea change. and i don't want to give the impression that the organ which the cancer arises has no importance. and what we have actually seen in these studies is that certain cancer types may not respond the same. so a colon cancer that has a-- mutation may not respond as a melanoma with a b wrap

mutation so i think it's a combination of understanding the genetics in the kanners that we treat and also understanding the effect of the organ where they come from. >> srennivasan: these clinical trials, are they different than the clinical trials we are used to where pun person gets the placebo and they might or might not improve and the other gets the real drug? >> i think they are different in a variety of ways. number one, most clinical trials in cancer have required specific disease types. so everyone that goes on that trial has one type of cancer. the clinical trials that we're doing now, so the called basket studies allow patients from any type of cancer to participate as long as they have a mutation in their tumor that we think suggests they would benefit from the drug being tesd. the other point is that these trials are typically not randomized trials. meaning that everybody that participates gets the drug. we know exactly what they're getting. and the reason for that is that the benefit that we're looking for in the form of

what percentage of patients have significant shrinkage of their tumor, is so high that it's previously unprecedented for those diseases. so we don't really need to do randomized studies because if half of the patients or more are having shrinkage of their tumor there is really no question that that treatment is better than the established care. >> srennivasan: dr. david hyman thanks so much. >> thank you. >> sreenivasan: before we leave you tonight, minnie minoso, known as the “cuban comet” has died. minoso made his baseball debut in cleveland in 1949 and was later traded to the chicago white sox. minoso played for 17 seasons, was a nine-time all-star and won three gold gloves, but he never made the hall of fame. minoso was 90 years old. coming up on the newshour tomorrow, the affordable care act goes back to the supreme

court this week. at stake are subsidies for millions of people in states that rely on the federal health insurance exchange. i need this subsidy. this is what makes me be able to-- to subsist. and it's just no way i could function without it. >> srennivasan: that's it for this edition of pbs fusshour weekend edition >> sreenivasan: that's it for this edition of pbs newshour weekend. i'm hari sreenivasan. thanks for watching. captioning sponsored by wnet captioned by media access group at wgbh access.wgbh.org >> pbs newshour weekend is made possible by: corporate funding is provided by mutual of america-- designing customized individual and group retirement products. that's why we are your retirement company. additional support is provided by:
