Over. Now sources say there is a worry the investigation, as well as separate congressional probes, will slow down. Republican richard bird, the chairman of the Senate Intelligence committee. An interruption in any of the access we have to the documents and personnel would be harmful to our investigation. It wouldnt in any way, shape or form preclude us from coming to a conclusion, but it might delay us. Reporter in recent weeks, sources say they have been intensely focussed on following the money, trying to identify who might have paid the hackers involved in russias campaign to interfere in the 2016 election. They are also scrutinizing the activities of President Trumps associates, including former National Security adviser, michael flynn, former campaign chairman, paul manafort, and former campaign adviser, carter page. All have contacts too or ties with russian officials. Ron whose coe worries that comeys firing could have a chilling effect. If the timing of this termination lines up with timing about a slow down in the investigation, the russia investigation, then i think there are serious, serious questions that are going to need to be answered by this white house and by the department of justice. Reporter acting fbi director, Andrew Mccabe met with the president today. The president wanted to discuss bureau morale. Tomorrow mccabe will be on capitol il testifying at a previously scheduled hearing. Earlier we mentioned the memo from rod rosenstein, the white house is pointing to that memo to justify President Trumps decision to fire comey. Rosenstein who has been the number two at the Justice Department for just two weeks specifically criticized a News Conference that comey held last july on the Hillary Clinton email investigation. Chip reid has more on this. Our judgment is that no reasonable prosecutor would bring such a case. Reporter on july 5, 2016, then fbi director james comey in a highly controversial press conference said he would not recommend prosecution of Hillary Clinton, but at the same time, he launched a scathing attack on her private email system, calling it extremely careless. Any reasonable person in secretary clintons position should have known that an unclassified system was no place for that conversation. Reporter comey later told congress he would keep them informed of any changes in the investigation. And on october it 28th. Just 11 days before the election, comey wrote to key congressional leaders, the fbi has learned of the existence of emails that appear to be pertinent to the investigation, and he reopened the clinton case. The emails were found on the laptop of disgraced former congressman anthony weiner, the husband of clinton aide huma abedin. Ach reviewing the emails, Comey Told Congress in another letter just two days before the election, we have not changed our conclusions that we expressed in july. It makes me mildly nauseous to think we might have had some impact on the election. Reporter despite that, comey defended his decision making. He argued he had little choice, because of the need to dispel suspicions of improper influence after thenattorney general Loretta Lynch had an impromptu meeting with bill clinton. Her meeting with president clinton on the airplane was the capper for me. Reporter robby mook, who was Hillary Clintons Campaign Manger tweeted, if members of congress are patriots, they will call for a special prosecutor to take over this investigation and take over this investigation and they will call for it i just saved a bunch of money on my car insurhuh.

The tunnel contains rail cars filled with radio active waste and the ground above them caved in yesterday. So far theres no sign that the radiation has leaked. John blackstone was there. Reporter with a machine blowing mist to keep down dust, workers began filling the gaping fourfoot square hole over the tunnel containing nuclear waste. Basically pouring dirt in, thats the plan . Yes. Reporter it doesnt sound like a very sophisticated solution. Its got to be done carefully. Reporter when the hole was discovered yesterday, much of the vast hanford site was put on lack down. Dirt collapsed into the tunnel. Nobodys involved. Theres no people involved. Reporter sirens go off, youre told to take cover. How unusual is that out there . Very. Ive never experienced it. Reporter this welder was working about a quarter mile away. Then when i see the fire trucks and ambulances and all that, that, that kind of sunk home. Like geez. Reporter the department of energy says no radiation has escaped from the damaged tunnel, hanford has a long history of problems. Plutonium used to make Nuclear Weapons for 40 years left a contaminated mess of buildings and equipment. This includes 56 milliongallons of radioactive waste stored in 177 underground tanks, some of which have leaked. Hanford is often described as the mostpolluted site in the country. A major earthquake, a major fire at the site with all these toxic, much of them flammable liquids, could cause a disaster beyond our imagination. Reporter the cleanup at hanford started more than 25 years ago, but its far from finished, scott, latest estimates show its likely to take at least another 30 years before the work sheer is complete.

But a new Study Reveals the dangers can occur just days after use. Reporter they studied 450,000 patients. The risk of heart attack after taking common painkillers like ibuprofen and naproxen rose. Dr. Steve nisen has studied the link between Heart Disease and nsaids. He says the risk has to be balanced with the been fit of pain re lief. Allowing people to suffer from pain is also not always acceptable. So we try to work with our patients, and we try to find the best pathway to relieving their pain without causing them to have a second heart attack. Reporter a 20 to 50 risk has to be put in perspective. For example, a healthy young man has much less than a 1 annual risk of a heart attack. Would you say then that the home message really applies to people at high risk for Heart Disease rather than the general public . There probably is some risk for everybody. But the absolute degree of risk is much higher for people that have Heart Disease. Its intermediate for people who dont have Heart Disease but have risk factors, and it is particularly low if youre young and healthy. He says nsaids always carry some risk. So people should take the lowest dose for the shortest time. Dr. Jon lapook, thank ,,,, jackson, board of trustees, thank you so very, very much for this great honor and privilege. I am honored to become a wildcat. In daytona beach, florida, many graduating students booed or turned their back on education secretary betsy devos as she spoke today at beth you know university. She said such historically black schools were pioneers in school choice. She later acknowledged because africanamericans were banned from many colleges. At one point, the University President warned the crowd that if the booing continued, their degrees would be mailed to them. It subsided after that. When we come back, with james comey gone, whats next for the fbi and the russia investigation. This portion is sponsored by td ameritrade. One day after the president fired fbi director job. Today, Senate Majority leader Mitch Mcconnell rejected calls for an independent counsel to investigate the russian ties. Vladimir putin told our liz palmer, quote, we have nothing to do with it. And thats the overnight news for this thursday. For some of you the news continues, for others, check back a little later for the morning news and cbs this morning. From the Broadcast Center in new york city, im scott pelley. This is the cbs overnight news. Welcome to the overnight news. Im tony dokoupil. The fallout continues over the firing of james comey. Some republicans are demanding answers, and democrats are demanding a special prosecutor. Major garrett begins our coverage. Reporter as comparisons to watergate swirled, President Trump met today in the oval office with president Richard Nixons secretary of state henry kissinger. President trump offered a brief explanation for his firing of james comey. He was not doing a good job. Very simply. He was not doing a good job. Reporter the white house described it as an erosion of confidence. Deputy press secretary Sarah Huckabee sanders. He had been considering letting him go since the day he was elected. Director comey has shown over the last several months and fra frankly the last year a lot of missteps and mistakes. I have confidence in him. Well see what happens. Reporter the president met monday with Deputy Attorney general rod rose ensteen and Jeff Sessions. Comey was the los angeles Fbi Field Office when he learned of his dismissal from television reports. Rosensteins hem memo to the president criticized comeys investigation into the clinton emails. Today on capitol hill. Vice president mike pence said comeys dismissal had nothing to do with russia. It was time for a fresh start at the fbi. Reporter but sources tell cbs news just last week comey asked rosenstein for more resources for the fbis russia investigation. Something the Justice Department denies. On monday, President Trump tweeted, the russiatrump collusion story is a total hoax. When will this taxpayerfunded charade end . But with the president s decision made without a successor in mind caught his star flatfooted. Why was he fired today . I think the biggest reason is really, really simple. I lost the confidence of the rank and file members of the fbi. Reporter on twitter this morning, the president pointed to democrats who faulted comeys handling of the clinton investigation. The democrats have said some of the worst things about james comey, but now they play so sad. Another tweet today called democrats phony hypocrites. Deputy attorney general rosenstein is held in high bipartisan regard. Attorney general Jeff Sessions recused himself from both the clinton email and russia investigations. But nevertheless played a role in comeys ouster and will help decide his successor. Now former fbi director comey was supposed to testify today on capitol hill. Instead, acting director Andrew Mccabe will take his place. But the Senate JudiciaryCommittee Still wants to hear from comey next week. Nancy cordes has the view from capitol hill. What happened yesterday was truly shocking. Reporter Senate Democrats accuse the president today of courting a constitutional crisis. He feels the dragnet tightening on the russia investigation. I believe thats why he let comey go. Reporter they argued there is now just one solution. We need an independent, special prosecutor. There has to be an independent, special prosecutor. If were going to get to the bottom of it, we need a special prosecutor. Reporter but Mitch Mcconnell said that would impede the russia investigations that are already under way. He accused the other side of shedding crocodile tears for comey. Our democrat colleagues complaining about the removal of a fbi director whom they themselves repeatedly and sharply criticized. Reporter democrats do have a history of slamming comey over his handling of the clinton investigation. The fbi director has no credibility. Reporter but pennsylvania democrat bob casey argues, its the timing of comeys dismissal thats problematic. Once the world knew that this investigation was under way you cant fire the investigator in the middle of an investigation. Reporter several republicans agreed, including the chair of the Senate Intelligence committee, richard bird. I think the timing and the reasons for the decision did, made little sense to me. And i dont think ive heard anything since last night that would clarify that in any way. Reporter he and his democratic counterpart mark warner have asked the now former fbi director to come before the committee next tuesday. I think jim comey ought to have his, if not his day in court at least his day on the hill to be able to lay out his side of the case. Reporter to show that their russia investigation is continuing at pace, the Senate Intelligence committee announced just tonight that they are issuing their first subpoena for documents belonging to the disgraced former National Security adviser, michael flynn. These are documents that the committee requested from flynn last month, but he declined to comply. Despite the controversy engulfing washington, it was all smiles and handshakes at the white house as President Trump played host to two top kremlin officials. Elizabeth palmer reports. Reporter all suited up for an amateur hockey match, president Vladimir Putin took the time to weigh in on washingtons latest scandal. How will the firing of james comey affect u. S. russia relations . Translator there will be no effect. Your position looks very funny to me. Dont be angry with me. We have nothing to do with it. Hes acting in accordance with confidence and the constitution. What about us . We came to play hockey with the hockey fans. Reporter officially, he denies russia even has an opinion. But he as as skilled a player on the world stage as he is on the ice. As the president scored in sochi, Sergey Lavrov was chalking up a win in washington meeting President Trump in the oval office. American reporters were shut out, so it was up to the russians to tweet this picture, and this one, with russias controversial ambassador, Sergei Kislyak who remains at the heart of the alleged collusion of the Trump Campaign and russias meddling in the last election. The pictures would have pleased kremlin spokesman Dimitri Peskov who in a quiet back room at the hockey arena explained that any mention of washington is so toxic in russia that real relations are a long way off. Its quite difficult about mr. Trump to speak about willingness. He is definitely under a huge pressure who still argue his presidency.

Theres been new attention focussed on the worlds oldest profession, prostitution. Police are using new tactics to combat the trade and others are pushing to make it legal. Lee cowen has both sides of the story. Reporter it was like any evening. Mt. Rainier hovered in the distance, and along aurora avenue, business was booming. Every city has its underbelly, where sex is bought and sold. Arrests are being made, but what might surprise you is just whos being arrested. Its not those selling sex, women and young girls, although to be clear, men are prostitutes, too. Instead, seattle has shifted their focus to arresting the customers, those buying the sex. Were not trying to harass women who are caught up in the trade. Were not trying to add to their burdens, were actually trying to help. Reporter six years ago, seattle city attorney, pete holmes adopted whats called the nordic law, a strategy pioneered in sweden that aims to reduce sex trafficking by cutting off demand. What we have been doing historically and what most of the country still continues to do is to further victimize women that are caught up in the life. Reporter according to the International Labor organization, Human Trafficking is a 32 billion a year industry, and many who are trafficked for sex are under the age of 18. Thats how old marin stuart was when she entered the trade. There was always something that kept me in the life. There were always reasons i needed to stay longer. I should have been murdered, many times. I should have died of an overdose, many, many, many, many times. Reporter how did you survive it . I dont know. I dont know. Reporter she considers herself an abolitionist, calling prostitution nothing short of modernday slavery. And the focus on buyers and not the sellers, she says is an enlightened, modern approach. The women are not being treated like theyre bad and dirty, and that this is just who they are. Youre going to need to hang in there though. Reporter she now works for a seattle nonprofit, a group that not only provides services for women, but also helps counsel the men who buy them, too. The men who are buying sex are buying it from a very broken place in their heart where theyre trying to fill a void, theyre trying to numb whatever pain they have, theyre trying to fill powerful, in control and desirable. You know, prostitution is called a trick for a reason. Hes paying for the illusion of concept, the illusion of mutuality, in fact what we know is that its not a mutual sexual experience. Reporter peter works here as well and leads a tenweek class on the consequences of prostitution. Is anyone caught buying sex in seattle is now required to attend that class by law. Until we take on the issue of demand and the issue of why men feel entitled to pay for sex in the first place, were really not going to be able to move the needle in any significant way. Lets gijust see where these girls are going to go for example. Reporter seattle is unique. Most cities have a zero tolerance approach. And you might be surprised to learn that includes the city of las vegas. If we suspected that they were involved in prostitution in this area, theyd be a prime target to watch. Reporter thats right. Prostitution is not legal in sin city. But lieutenant Patricia Spencer of the vice and Sex Trafficking Department says most people seem to think otherwise. Its everywhere. Its not just on the street. Its not just in a casino. Its everywhere. Reporter unlike seattle, las vegas cracks down on everyone, the sellers as well as the buyers. Lieutenant spencer doesnt see that as victimizing the victims. In her experience, the arrests help identify those too afraid to identify themselves. Ive talked to numerous survivors that say it saved their life. Reporter being arrested. Being arrested. We open the door for help. And if we dont do that, whos going to do it. If i dont offer them help, whos gonna . No one. Reporter rethinking just how or whether to crackdown on prostitution has been making headlines. Last year while acknowledging the harm that comes with the sex industry, Amnesty International called for the decriminalization of consensual sex work saying laws against that force women into the shadows, which can compromise their safety. It doesnt help people with no options to take away their source of income. But it sounds good. Reporter Carolyn Mccloud calls herself a sex worker, not a prostitute. Shes a see at many mother of two who despite the fact that its illegal sees it as her right to run her body as a business. I choose this. I say to people when they say no one would choose this, i say, i do. I choose this, because im proud of what i do. Reporter she knows shes largely the exception and sympathizes with those who arent doing this willingly, but she says the best way to protect them and at the same time to preserve her rights is to legitimatize what she does. It would bring it out of darkness and back streets and into the light. Reporter what might decriminalization look like . Carolyn says just the way she practices her sex work now. She has no pimp. She doesnt roam the streets. She works out of a condo she rents with two other women and she says they all have strict safety guidelines. All of my clients need to have references from other sex workers. And if they dont have references, then potential client would have to give me their real first name and their real workplace, and i will call them at work through the main switchbod of that. Reporter her point, and this is controversial, is that sex traffickers dont generally trade in places where buying sex is permitted. And that, she says, keeps everyone safer. Theres a Huge Population of sex workers who are doing this in aay and you dont see us, because were not causi problems. Reporter sharis ranch may be the Halfway Point in this debate over prostitution. Its one of a handful of brothels in rural nevada where prostitution is legal but regulated under state law. Alissa, a single mom left working the streets of seattle left to move here where she feels someone is watching out for her. You come here and sit down and tell me, this is what i want to happen. I want this and this and this and this to happen, and i tell you what im going to charge for that and what im comfortable doing and what the rules are. Theres no gray area. Reporter what do you say to people who think this is just a crazy lifestyle that no single mom should be doing this . I tell them its not their life and you dont walk in my shoes every day. I live a very clean, safe life. I go home, do my cooking, cleaning, chores. You dont grow up thinking i want to be a prostitute when i grow older many but things happen in your life and you make different decisions. Reporter venus, the madam says they give some protection. The states watching us. And theyre not going to play with any funny business. So everything is up and up legit. Reporter still, critics say anything short of outlawing prostitution all together amounts to the legal acceptance of objectifying women. Is there going to be a theme . Yes. Reporter he says thats not what this is about. She sees it as giving women a choice, offering a safe place to make a new start. This is just a means to an end. This should be a steppingstone into something better. And greater. Reporter alissa, caroline, marin. Each a different face of an ageold question, is prostitution an illicit vice . Or a lawful business, sex work . Or sexual exploitation. The divide is deep and the battle lines are being drawn, however uncomfortable, an issue long in the shadows seems to be hiding no more.

More than half the fruits and vegetables sold in the u. S. End up in the garbage, mostly because they go bad before theyre eaten. Well, a company in california has a new technique to extend the shelf life of fresh food by up to five times. The. Reporter on this lush hillside farm, its not just the views that grab your attention but the rare produce on the treeses including these aptly named caviar limes. Once you pick it, theres a tierm going off. Reporter theyre prized because of their acidity and texture, but they only last a week to ten days after picked, making shipping and distribution difficult. Thats where a scientist comes in. Rusky teamed up with him more than two years ago. We use food to preserve food. That simple. That simple. Reporter they start with material like these frozen grape skins, extract molecules and mix them up. The powder is mixed with water and sprayed on fresh produce. When it dries, it leaves behind an imperfect septemberably thin layer of plant material. And that thin barrier slows down the rate that water gets out of the produce and slows down the rate oxygen gets in, and by doing that, we can naturally preserve the shelf life. Reporter how much longer does the average piece of fruit last with your product on it . Each piece of produce has different characteristics. We can get twice to five times the shelf life. Reporter so youre basically monitoring how this lemon is dying over time . Exactly. Reporter this time lapse room is where they study the results. By day five, the untreated strawberries on top rot. But the treated ones on the bottom are still good to eat. Its fda approved, and the thin layer it leaves behind is edible and tasteless. It would replace the wax that is often used on Grocery Store produce. Youre going to have some people who look at this and say this is franken food. I dont want that sprayed on my food, because that reminds me of a pesticide. How do you get over that hurdle with those people . The way we try to do this is be very open with people about what were doing. Were taking stuff youre eating already in every bite of your produce and just reapplying exactly where it is on the produce. Were putting it on the outside. Reporter the Company Hopes their product will help with Global Hunger and places without access to refrigeratoration. It could also reduce food waste. Here in the u. S. , 24 of produce is tossed out before it reaches the Grocery Store. Another it 28 is thrown out at home. No one technology is going to solve a problem this big. Fundamentally, this problem is driven by our habits around food. And so we cant technology our way out of that. I think it needs to be paired with really careful shopping. Reporter epeel is in talks with brands. It remains to be seen whether using the product would pass the cost along. Weve been able to do two to three times the shelf life, and im super happy to see the results. Secretary of state Rex Tillerson is in fairbanks, alaska. They will be discussing the thorny issue of Climate Change. President trump has called Climate Change a hoax and has made conflicting statements about whether the United States will adhere to the paris accord. On the bottom of the world, the largest predators are suffering from a rise in sea temperatures. Our Mark Phillips reports for his series, the climate diaries. Reporter a pod of killer whales is spotted crossing a stretch of open water. Researchers jump into small boats to chase them, just like in the old days. This hunt, though, isnt about killing whales.
