Also here tonight, the Hillary Clinton email scandal, its deepening. It took long enough but at long last, the fbi has begun investigating the security of mrs. Clintons private email server and its purported classified contents. The fbi investigation comes only days after government watchdogs for the state department and Intelligence Community ask the Justice Department to explore whether classified material was improperly shared and or stored on clintons private account . Well have the full report for you and whether it may mean the end of the clinton president ial candidacy. In cleveland tonight, lots of president ial candidates in attendance. The republican kind.

So tonight, well have everything you need to know ahead of tomorrows debate which will be anchored by megyn kelly, bret baier and chris wallace, 9 00 p. M. On the fox news channel. President obama using some of the ugliest partisan rhetoric trying to sell his nuclear deal with iran, mr. Obama declared if congress were to block the agreement next month it would quote result in some form of war, and mr. Obama compared republicans opposed to deal with iran to extremists, iranians, the hardliners who chant death to america. The president s offensive hyperbolic language two days after a wall street journalnbc poll shows opposition to the deal doubling since june. Fox News White House correspondent kevin corke with our report. The choice we face is ultimately between diplomacy or some form of war. Reporter with that, president obama drew the starkest contrast possible between his vision of a nuclear weaponfree iran and one in which an embolden tehran pushes the world toward military conflict. Ive had to make a lot of tough calls as president , but whether or not this deal is good for American Security is not one of those calls. Its not even close. Reporter the president s speech at American University was meant to debunk arguments against the iran nuclear deal, and in many ways mirrored president john f. Kennedys famed strategy of peace speech delivered in 1963 on the same campus. A pursuit of piece is not as dramatic as the pursuit of war. But its so very important. Reporter important and definitely political for the president , who today likened opponents of the deal on capitol hill to rabblerousers in iran. Its those hardliners chanting death to america who have been most opposed to the deal. Theyre making common cause with the Republican Caucus. [ applause ] reporter that Republican Caucus in the senate is 54 votes strong with 44 democrats and 2 independents in the minority, needing 67 vote toefrs ride a president ial veto, gop leaders need to flip 15 senators by september to defeat the agreement. I wont let party, pressure politics interfere with doing what i think is right. Reporter meanwhile three House Democrats including steve israel in a Party Leadership position joined the gop majority in issue onning posing the deal. New yorks nita lowey saying, quote inspection transparency remains a major issue, during his visit to capitol hill, the International AtomicEnergy Agency director general said though portions of the deal reached between the iaea and iran cant be studied by u. S. Lawmakers, that shouldnt be a cause for concern. Im confident we have the expertise and experience to do the job. Reporter of course the hard sell has continued throughout the day, lou. In fact, the president went online on twitter to try to defend the iran nuclear deal. In fact at one point he tweeted this is a strongest Nuclear Agreement ever negotiated. He did not however, i should point out, mention the incendiary language he used to describe opponents on capitol hill. Lou incendiary and offensive. Is there a strong blowback to a president of the United States calling his Republican Opposition akin to extremists in iran . You have to admit, the second you heard it lou, in watching the speech, even here at white house, you heard a gasp, an audible deep breath collectively. Its that language that wont make you friends on the hill, but worse, its not terribly president ial, and as i pointed out in the piece were only talking about 13 senators that have to be flipped for the senators to be able to stop this deal and again, this is not the language that will help the president not far from here. Lou kevin, thank you so much, we appreciate it. Kevin corke from the white house. And as kevin suggested more extreme language today on the part of the iranian leadership. A Senior Iranian official warned of an impending third world war that will be sparked he said, by terrorists. Iran blamed the United States and nato for fostering the conditions that would lead to world war ii i even as this president is pushing, trying push through conditions, a deal that has not thoroughly vetted by his own National Security officials. A federal Appellate Court today struck down texass voter id law. The fifth Circuit Court of appeals in new orleans ruled that the republicanbacked measure violates a Voting Rights act and has as it termed it, a discriminatory effect on minorities. The ruling is a victory for president obama whose Justice Department has argued for years that the texas law would prevent as many as 600,000 voters from casting a ballot. Other republicancontrolled states including wisconsin, north carolina, have all passed similar voter id measures but the texas law signed by then governor rick perry is considered one of the nations toughest. More, more judicial process certainly under way including the prospect of appeal to the supreme court. Throwing the Clinton Campaign into high dungeon and high anxiety whether her president ial ambitions can be fulfilled, the fbi is investigating her private email system to determine whether the former secretary of state compromised classified information, jeopardizing National Security. Two inspector generals state and the Intelligence Community ask for the probe of her conduct. Federal investigators have reportedly contacted now the i. T. Company that helps maintain her private server and contacted mrs. Clintons personal attorney who has a copy of her emails including those with classified information on a thumb driver, a thumb drive again in his possession. Fox news chief White House Correspondent ed henry with our report. Reporter when your team has to again stress technically youre not under criminal investigation, as Hillary Clintons allies did for the second time in three weeks, its a sign your campaign hit major turbulence. Clintons selfinflicted wounds are helping Bernie Sanders. He vaulted to within six points of clinton in New Hampshire. In a new wmur survey. And since the margin of error is 5. 9 points the pollster declared its a statistical tie. They want a movement that stands up and says enough is enough. Reporter sanders made clear he has no plans to attack clinton and may not need to stoke the flames, which were already burning. As fox confirmed, the fbi lunched an investigation into the security of her personal email server, and the fbi asked clintons personal attorney David Kendall about the security of a thumb drive he has with copies of her email. Kendall telling fox in a statement, quote, we are actively cooperating. Advisers to clinton stress shes not the target of a criminal investigation, similar to last month when it was revealed two inspectors general determined there may be hundreds of classified emails in the server. With clintons chief supporter will say. Thats the pastime of republicans. Reporter except republicans are not driving the fbi review. And while it is starting as an investigation of the server, that server was set up by clinton and she could ultimately become the target. At the least, clinton will face political fallout from promises she made at her march News Conference that turned out not to be true. The system we used was set up for president clintons office, and it had numerous safeguards. It was on property, guarded by the secret service, and there were no security breaches. Reporter the Washington Post reported the fbi learned she moved her email to a different server and it was not always reliable. Allies of clinton say that New Hampshire poll shows that sanders support is leveling off and clinton in the end will win the nomination. As for the republicans, aides say clinton will be on a plane she will not be watching, at least not live. Lou . Lou all have the forecast for a distant election. Ed henry as always, great reporting, thank you. Up next, president obama making an urgent appeal to congress to save his nuclear deal with iran.

The secretary of state says it risks, quote screwing irans Supreme Leader. The secretary of state telling the atlantic magazine, quote, the ayatollah constantly believed that we are untrustworthy, that you cant negotiate with us, that well screw them. Congressional rejection, as he put it, will be the ultimate screwing. End quote. Our top diplomat apparently worried about the feelings of the ayatollah. A man who calls america the great satan and has long vowed to annihilate israel. An interesting perspective. Joining us tonight fox news National Security analyst, k. T. Mcfarland and former u. S. Ambassador to the United Nations, American EnterpriseInstitute Senior fellow john bolton, also Fox News Contributor. Thank you, both for being here. Let me start k. T. , with you. The president comparing republicans to iranian hardliners who chant death to america. Has the president gone simply off the rails, over the top and become ultimately offensive in his rhetoric . Not only offensive but irspovenlt hes saying its either this deal or its war. And implying its nuclear war. And when he says well, the republicans in congress are like the hardliners in iran chanting death to america talking about war. Guess who the hardliner is in iran saying. That thats the Supreme Leader. Just last week, after this deal was inked and agreed to. The Supreme Leader issued a pamphlet and had a number of ways he was planning to annihilate israel, trick america and destroy the great satan. So if this is the partner we have, its very unlikely theyre going to keep this agreement. Theyre probably going to cheat. The president and secretary kerry think they have all this snapback provisions, thats not going to happen. Once the contractors let. Thats the end of it. The thing that makes me the most upset is in the president s remarks today and throughout the justification of this by the secretary of state and the president , they dont talk about the most important thing. The most important thing is not what they think or the republicans think or the pundits think, its what the other countries in the region think, theyre look at this deal and saying we dont believe it, we think iran is going to be a threshold nuclear state. Were getting nukes of our own and you have the most dangerous thing of all which is a Nuclear Arms Race in the most unstable part of the world. Lou and john, one of my greater concerns here, if you will, is this is an administration that doesnt understand. Each one of the elements that he decides to attach to great hyperbole and insult all could have been constructed in a good faith bargain with any nation had it been a treaty, had it been above board, had it been transparent. Had it been verifiable, had the facilities been inspected by u. S. As well as global, other global interests. What in the world . I have to tell you, im more concerned about an administration that doesnt have the capacity to understand that basic fundamental truth. What do you think . Well, i think the administration headed down the wrong path from moments after the president took the oath of office on january the 20th, 2009. And he conceded as early as a few months after that, that iran could keep uranium enrichment facilities active. Thats the beginning of the mistake that simply led down hill from there. You know what secretary kerry and president obama are really suffering from, the state department has a word for it, its called going native. And it means that a diplomat accredited to represent the United States visavis a country like iran actually ends up sounding like an iranian diplomat. Thats what we have here. Thats what explains the president s speech and john kerrys remark. Lou k. T. , i think johns exactly right. Yeah. Lou the reality is the secretary of state of this of the United States of america is taking the perspective of the people across the bargaining table from him over the course of some i dont know what the number of meetings has been. Its required more than 70 trips across the atlantic to come up with a document they havent even read, much of it, and a document they insist is absolutely credible, which they took to the United Nations before congress. Why shouldnt the congress of the United States, democrat and republican, in a bipartisan fashion tell this administration to go to hell . That this is no way in which to conduct Foreign Policy. This is the most significant Foreign Policy initiative and agreement of a generation. It will affect our children, it will affect our grandchildrens generation if Nuclear Weapons proliferate around the middle east. This is not a treaty. This is not submitted to the United States congress for ratification. This is an agreement between not the United States of america and the government of iran, its between president obama and the government iran. Fact that he has end run the United States congress boy sending it to the United Nations and giving it to congress not as a treaty but opportunity they get on chat about but not really to disagree with, the fact hes done that and now the fact theyve revealed there are secret agreements, secret protocols nobody is allowed to look at. Congress isnt allowed to look at. It doesnt pass the smell test lou. Lou john bolton, you get the last word, a quick one, if you will. Congress, if they want to have a say in this needs to step up and threaten the administration with cutting off state department appropriations, cutting off funding to the iaea, not confirming administration nominees. You cant remonstraight and say this is terrible. I see no evidence they want to do that. Lou i promised you the last word, i got to say this. This Republican Congress has not delivered on a single, a single promise of action, not a single threat that it has made it connection with Foreign Policy, so i dont envision and want to hear quickly from you, i dont see the
