The greek government said that just after the plane left its air space, it swerved wildly and plummeted before finally falling off the radar screen. But now egypts head of air Navigation Services has denied that, saying the plane was flying normally when last seen on egyptian radar. Meanwhile, data published by an appears to have show there was smoke on board the plane in the minutes before it crashed. But experts say the smoke alarms could also have been trigerered by a sudden loss in pressure. Even the planes flight recorders, are socalled black boxes, may not tell us what wrong. It depends on the information they contain if theyre recovered. Retired general was chief of staff of the egyptian air force. Well find what happened. God willing, well find out what happened. Yes.

Thanks, holly. Hillary Clintons Campaign is launching a new phase of coordinated attacks on donald trump. A new ad tries to connect the maal estate mogul to the housing but her cam trapaign still f a tough democratic primary fight with senator Bernie Sanders. Nancy cortes is covering the twotrack fight. Good morning. This is the Clinton Campaigns first big coordinated attempt to define donald trump. They and their surrogates are going after one of his biggest selling points, his business experience. If there is a bubble burst, as they call it, you know, you can make a lot of money. Using his own words against him, clinton supporters and lawmakers in more than half a dozen battleground states will all argue today that trump rooted for the Housing Market to collapse. I sort of hope that happens because then people like me would go in and buy. Campaigning in stockton, california, former president bill clinton had this message for democrats, who are worried that polls now show trump pulling even with his wife. Just relax. In the end, the American People they only have so much bandwidth to think about politics. He said he learned that first hand when he won the nomination in 1992. When i showed up at the convention, a majority of the American People didnt know that hillary and i had a child. But Hillary Clinton cant shake sanders, who predicted monday that this years convention could get messy and urged her to debate him ahead of the california primary. The Clinton Campaign said no dice, arguing Hillary Clintons time is best spent campaigning and meeting directly with voters across california and preparing for a general election campaign. I was disturbed but not surprised to hear a few hours ago that secretary clinton has backed out of the debate. [ booing ] back in 2008 when she was the one trailing, clinton sounded a lot like sanders today. Its the toughest job in the world. You should be willing to campaign you should be willing to debate any time, anywhere. The dnc is giving sanders one thing that hes wanted, influence over the Party Platform to be unveiled at the convention this summer. He gets to name five members of the 15member committee. Thats nearly as many as the likely nominee gets. Gayle, she gets six. Allight. Thank you very much, nancy. Donald trump is getting personal with his attacks on the clintons.

Besides senator bob corker, donald trump has also sought advice from two former secretaries of state. Polls are showing most republicans have begun to fall in line behind donald trump. Thats why the presumptive nominee is also attracting more and more support much rather have policy and issues. Donald trump plays issues and attacks with equal emphasis. Theyre dirty players. Theyve been dirty players historically. I have to fight back the way i have to fight back. On monday, trump released an internet video again highlighting unproven Sexual Assault allegations kbens former president bill clinton. The same day, trump sat down with Senate ForeignRelations Committee chairman bob corker, who later acknowledged the uncertainty his foreign counterparts feel towards trumps unconventional, and to some, alarming Foreign Policy proposals. Some of the comments relative toea sprding nuclear arms in japan and south korea i would disagree with. My sense is that he will evolve. That evolution is already evident as trump fumbles with a highprofile gun rights issue. Were getting rid of gunfree zones, okay . That was trump friday after landing the National Rifle associations endorsement. This was sunday. I dont want to have guns in classrooms, although in some cases teachers should have guns in classrooms. Hillary clinton attacked trump as dangerous and radical on the issue. Trump is now shifting, saying he would only get rid of gunfree zones in some cases. And only School Resource officers would be armed. And trumps fascination with conspiracy theories continues. Trump told the Washington Post the 1993 death of Clinton Family confidant vince foster was, quote, very fishy. Investigators ruled his death a suicide. Thanks so much, major.
