>> as president and as commander in chief i take full responsibility for all our counter terrorism operations including the one that inadvertently took the lives of warren and giovanni. >> reporter: president obama at times emotional, apology for the accidental deaths of two hostages including an american held by al qaeda since 2011. maryland doctor warren weinstein and giovanni la porte toe were inadvertent victims of a drone strike meant to hit an al qaeda compound. >> as a husband and as a father i cannot gib to imagine the anguish that the weinstein and lo port toe families are enduring today. i realize that there are no words that can ever equal their loss. >> reporter: u.s. intelligence confirms the men died january 14th in a strike that also took the life of ahmed if a ruk, also an american. the white house offered few details about the action declining to say where and when the strike took place and why it took three months to tell the american people. senior intelligence officials tell fox news that the strike was not ordered by the president himself, nor was the january 19th strike that killed adam gadahn a 36-year-old oregon man who appeared in al qaeda videos. u.s. officials said they didn't realize until weeks later that weinstein tied in the initial attack? in the aftermath of a situation like this it raises legitimate questions about whether additional changes need to be made to those protocols smr in a statement weinstein's wife wrote there are no words to do justice to the disappointment and heart break we are going through. those who took warren captive bear ultimate responsibility. neighbors also mourned the loss of a humble doctor whom they said just wanted to serve others. >> our hearts are broken. we have great sympathy and, you know, i just want to let them grieve. >> reporter: along with sorrow there was outrage. maryland congressman delaney said weinstein deserved better. >> we had several years to find him and we didn't find him and because we didn't know where he was we were involved in this tragic accident that resulted in his loss of life. his country let him down. >> reporter: powerful words interest a man who spent several years trying to earn his release. i should point out we learned that the white house will compensate the wine teen and lo port toe families. we also learned the president will dee classify this mission after a thorough review. >> kevin, thank you. tonight we are learning that the clinton foundation bill hillary and chelsea's charity will refile tax returns for the last five years because of quote, errors in reporting about certain contributions. its part of a tail that could spell serious trouble for the hillary clinton presidential campaign. big money, tens of millions of dollars and allegations of influence peddling and even bribery. even russian aggression and iran's nuclear program factors in. much of it is detailed in a new book clinton cash by peter schweizer. i was given early access to the book and talked exclusively with its author. the stories span the fwloeb but perhaps the one with the most geo political consequences starts in kazakhstan. consider the stunning case of kazakhstan and how american uranium ended up in the hands of the russians. >> september 6, 2005 bill clinton shows up in kazakhstan where frank justra a canadian investor has been trying to get control to buy a couple of uranium mines and he became partners in a way with bill clinton working on philanthropic activities. >> i came to him with an idea about creating anish testify to alleviate poverty. >> furthermore frank justra has been involved in helping to facilitate speaking engagements for the clintons. >> they were whisked to the presidential palace of president bayoff in kazakhstan. it's a fascinating story because everybody walked away from the table that night with somebody. >> the story caught the attention of pulitzer prize winning new york times reporter joe becker. >> what the president got was this huge propaganda could you. bill clinton endorse ds the progress that kazakhstan had made in terms of their own democracy which was interesting given that president nazarbiof was elected with 96% of the vote. >> bill clinton has a public press conference with president nazarbiof where he praises his rule and praises his human rights record but the bottom line is after they leave a couple of days later frank justra gets his uranium concessions which end up being enormously lucrative to him and to a small group of canadian mining investors. >> his company was like a bit player and really had gone from worthless shell company overnight got this huge uranium mining deal and then soon after that bill clinton got a huge donation $31 million from frank justra to his charitable foundation followed by a pledge to donate $100 million more. >> our calls to the kazakhstan embassy were never returned. we talked to frank justra who told us he considers this an old story and said that he's not interested in politics. meanwhile, his defenders insist that no undue influence was exerted in kazakhstan because the deal did not require the kazak government's approval. >> the problem is there are corporate records that indicate very very clearly that the kaza government did have to sign off and approve. >> that's what we're looking at here? >> exactly. which is the amended memorandum of understanding that's dated september 15th 2005 between the ministry of energy of the republic of kazakhstan and the atomic agency in the kaza government. there's no way they can argue the kaza government was not a party to the organization. they were signators to this agreement. >> and there's a post script. >> kazak officials wanted to take an equity stake inest i think house which is a u.s. company that works in the civilian nuclear field. >> when you have a sensitive company like westinghouse that requires review by the u.s. government. >> so the potential investors came to america to see the man who could make things happen. >> frank justra arranged for can kaza officials to go to bill clinton's house in chap a kwa. when i first contacted both the clinton foundation mr. clinton's spokesman and mr. justra they denied any such meeting ever took place. then when we told them we had already talked to the head of kaza who told us not only all about the meeting but has a picture of him and bill at the home in chap a kwa and that he proudly displayed on his office wall they then acknowledged that yes, the meeting had taken place. >> so what happened to justra's company that benefited from that deal in kazakhstan? after a merger it became a uranium giant called uranium one and then the russians bought it. >> uranium one became very active in acquiring uranium assets actually in the united states itself. why 2008 2009 they were collateral attractive target for the russian government. >> and the russians acquired that target. >> they would acquire what would amount to 50% of projected uranium output by 2015. >> in other words, russia now controls what was projected to be up to half of america's uranium. >> now, does secretary clinton factor into this? >> for that deal to go through it needs federal government approval and one of those people that has to approve that deal is secretary of state hillary clinton. >> who as senator clinton was vigorously opposed to these kind of buys from countries into u.s. property. >> that's a great point, bret. you remember the dubai ports deal which she was opposed to. >> we believe that no foreign government should control our ports. >> in this particular case we're talking about uranium, we're talking about things that relate to the nuclear industry we're talking about the russian government. >> which already provides equipment, material to iran. >> that's correct. >> just how deeply those uranium interests were invested in the clintons was not disclosed by them or their foundation. schweizer learned about that by scouring canadian tax records. >> so let's go to the fern wood document. >> fern wood foundation is an entity in canada controlled by ian tellfer who ends up being the chairman of uranium one. ian telfer in 2007 made an individual contribution to the clinton foundation. the problem is based on canadian tax records in this particular case made a payment of $250,000 to the clinton justra sustainable growth initiative. they are required to disclose the donation they failed to do that. this is a hidden contribution and over the course of a couple of years you're talking about more than $2 million from the fern wood foundation to the clinton foundation. when you actually go to the clinton foundation website itself on disclosures and type in fernwood you find no contributions listed whatsoever. >> no results match fernwood. >> that's right. >> uranium one and ian telfer declined to comment. what this amounts to in the end is a russia company essentially controlled by vladimir putin will now be in charge of a substantial portion of american uranium. russia sends uranium to its client state iran. so american uranium could well be sent to the very nation we're negotiating with to try to slow its ability to develop a nuclear weapon. thus we see how far reaching the effect of the clinton blur as schweizer puts it can be. neither the former nor the hopeful president clinton has responded directly to the new reports about the foundation's financial connections or the speeches but another clinton was asked about it. chief white house correspondent ed henry is in new york with the response. >> reporter: chelsea clinton who is taking on a bigger role as her family deals with this latest crisis today rushed to the defense of the foundation which has been battered by allegations that foreign governments received favors in exchange for hefty donations. during her mother hillary clinton's time as secretary of state. a revelation in the new book clinton cash that's roilg the presidential cane. >> we will be even more transparent that to eliminate any questions while we're in in time we won't take new government funding, but that the work will continue as it is. i think that's the right choice for the people who are being affected by that work. >> reporter: she was pes pressed at a panel on women's rights why the foundation took big money from countries like saudi arabia with abysmal records on women's right which is a small part of the allegations piling up as the new york times and fox news report the family and its foundation pocketed millions of dollars from donors tied to a business teal that allowed russian president vladimir putin to essentially corner the market on american uranium production a deal signed off in part by hillary clinton, despite an official memorandum of understanding signed by advisors to clinton and president obama to avoid such conflicts. >> i think the goal of the memorandum was to ensure that even the appearance of a conflict of interest was -- was avoided by ensuring that there was greater trans fairnessy. >> reporter: despite those vows the foundation is now planning to refile at least five annual tax returns after a reuters review found major errors in how they reported donations from foreign government's. while the washington post revealed former president bill clinton was paid at least 26 million sooipd in speaking fees from entities that are also major donors to the foundation. leading republican presidential hopeful carly fiorina today to charge it's the clinton way, raking in millions from foreign governments behind closed doors while making promises about transparency that they never intended to keep. clinton campaign folks man brian fallon declared nobody has produced evidence that she took action as secretary of state to help clinton foundation donors and added of the author peter schweizer it is impossible to view this allegation as anything other than just another in the many partisan conspiracy theories advanced in the clinton cash book. that may be undermined by the fact that schweizer isn't just going after clinton or democrats. he says his next project will target jeb bush. >> after hillary clinton she may face heat on another big topic, republican tray gowdy chair of the special house committee on benghazi declaring he wants her to testify either in may or june at the latest not just on the terror attacks, but also on what happened to her e-mail. we will have much more on that book and its

behind. topping the list of leaders of the past vice president joe biden, jeb bush and hillary clinton. rubio bounced on reports that while mrs. cli secretary of state her department negotiated a uranium deal with kazakhstan while the clinton foundation was accepting millions of dollars from russian interests and bill clinton was raking in millions in speaking fees. >> the allegations are serious and troubling, the notion that somehow official u.s. policy was influenced by donations made to a private foundation and through speaking fees to the former president. that's a troubling allegation if proven to be true i think is a disqualifier. >> reporter: kentucky senator rand paul with his appeal to younger voters is the only candidate to virtually tie clinton's within the 3 point margin of error. jeb bush and marco rubio are only a point off the pace in the early polls which rubio tries to downplay les he draw the scrutiny that trips up front runners. >> this campaign will be decided on the basis of a race and a campaign not on what's going on in april of the year before. >> reporter: most of the goep hopefuls track to iowa or to vegas for the republican jewish coalition meeting. he spent $20 million helping newt beginning rich and $30 million helping mitt romney in their 2012 campaigns and it is expected to help rubio. >> we would love to earn his support but that's
