Hillary Clinton — believing leaks by President Barack Obama staff's triggered the federal probe of her private email account — ripped into the commander in chief, telling him, during a tense meeting, "What I want for you to do is call off your f–king dogs, Barack!"The profane attack came during a tense meeting in the Oval Office that was called by Hillary, against the advice of her husband, former President Bill Clinton, according to bestselling author Ed Klein's new book, "Unlikeable: The Problem with Hillary." The explosive tome, published by Regnery, hits bookstores next week and was excerpted Wednesday in The New York Post. During the private meeting, Clinton called the meeting because she felt she was "being persecuted for minor, meaningless violations," Klein writes.But Hillary lost her temper and swore when Obama at first claimed he didn't know what she was talking about."He was almost being deliberately dense. It really angered her," a Clinton source told Klein.After Clinton's tirade, Klein writes that Obama responded, "There is nothing I can do for you one way or another. Things have been set in motion, and I can't and won't interfere. Your problems are, frankly, of your own making. If you had been honest ..."According to Klein, Clinton then interrupted, "There are always haters out there to get the Clintons."Klein writes that Clinton later thought she had been too weak in her response to the president.A Clinton spokesman, Nick Merrill ripped Klein's new tome, telling The Post: "Another book? Someone should do a book about Ed. They could call it 'Bulls–t: The Problem with Anything Ed Klein Writes.'"The only true thing about him is his consistent and utter lack of a relationship with the facts. He has more hair than credibility, and the man is bald. So we're not going to get down in the gutter with him and his outrageous fabrications," Merrill continued.Klein also writes that the former secretary of state and Democratic presidential front-runner has "mounting health issues" and is worried she's too unwell to try to capture the White House.Clinton is "frequently plagued" by "blinding headaches," Klein writes, according to The Post.In addition, Klein writes, Clinton has suffered from insomnia, which has drained "her energy just when she needed it most for the campaign," Klein writes.Clinton suffered from a serious blood clot on her brain in 2012 that has left her "constantly worried" she'll develop another one, Klein writes. Clinton says she's in good health and released a report from her personal physician confirming that assessment.
