It appears the detente between Fox News and Donald Trump is over. 
 
 Last night, Trump blasted Megyn Kelly in a series of tweets and retweets, saying “perhaps she could take another eleven day unscheduled vacation.” 
 
 I liked The Kelly File much better without @megynkelly. Perhaps she could take another eleven day unscheduled vacation! — Donald J. Trump (@realDonaldTrump) August 25, 2015 
 
 He then retweeted another user who referred to Kelly as a “bimbo.” 
 
 "@mstanish53: @realDonaldTrump @megynkelly The bimbo back in town . I hope not for long ." — Donald J. Trump (@realDonaldTrump) August 25, 2015 
 
 Fox News chairman and CEO Roger Ailes fired back in a statement Tuesday, blasting the GOP front-runner’s “surprise and unprovoked attack on Megyn Kelly,” who he said “represents the very best of American journalism.” He also called on Trump to apologize. 
 
 Trump, in a response, said in a statement “I do not think Megyn Kelly is a quality journalist.” He added that he hoped that he “will be proven wrong and she will be able to elevate her standards to a level of professionalism that a network such as Fox deserves.” 
 
 Trump also cited his strong standing in the GOP race, including a poll out Tuesday showing him well ahead in South Carolina. 
 
 Fox commentator Sean Hannity also took Trump to task for his latest attacks on Kelly. In a tweet on Tuesday, he described Trump as “my friend,” but also called on the billionaire real estate developer to lay off Kelly. 
 
 My friend @realDonaldTrump has captured the imagination of many. Focus on Hillary, Putin, border, jobs, Iran China & leave @megynkelly alone — Sean Hannity (@seanhannity) August 25, 2015 
 
 The dispute between Fox News and Trump began following the opening GOP debate in Cleveland on Aug. 6. Trump complained that he’d been treated unfairly by Kelly when she asked him about his past comments on women. He told CNN the day after the debate: “You could see there was blood coming out of her eyes. Blood coming out of her wherever.” 
 
 His comment sparked widespread criticism, including from Fox, though Trump denied he was referring to menstruation. In the days that followed, it seemed as if Trump and the network had mended fences, a truce that now appears to have been short-lived. 
 
 Here’s the full statement from Ailes: 
 
 Donald Trump’s surprise and unprovoked attack on Megyn Kelly during her show last night is as unacceptable as it is disturbing. Megyn Kelly represents the very best of American journalism and all of us at FOX News Channel reject the crude and irresponsible attempts to suggest otherwise. I could not be more proud of Megyn for her professionalism and class in the face of all of Mr. Trump’s verbal assaults. Her questioning of Mr. Trump at the debate was tough but fair, and I fully support her as she continues to ask the probing and challenging questions that all presidential candidates may find difficult to answer. Donald Trump rarely apologizes, although in this case, he should. We have never been deterred by politicians or anyone else attacking us for doing our job, much less allowed ourselves to be bullied by anyone and we’re certainly not going to start now. All of our journalists will continue to report in the fair and balanced way that has made FOX News Channel the number one news network in the industry. 
 
 And Trump’s full response, via Politico: ||||| Donald Trump is the Republican frontrunner for president, a fact that has befuddled just about everybody—except perhaps Trump himself—and spawned countless theories: He's leading because Americans are frustrated with politicians and want a straight-talking outsider. Because he shamelessly caters to paranoid conservatives. Because he's famous. He's not politically correct. He never says sorry. He's unfailingly entertaining. And the press can't resist him. But there's another reason that no one has considered yet, a secret weapon that has propelled past charismatic politicians like Bill Clinton and Theodore Roosevelt to the White House: hypomanic temperament. 
 
 To be clear, I’m not using my authority as a professor of psychiatry to call Trump mentally ill. Hypomanic temperament is not an illness. It is genetically linked to bipolar disorder and manifests the same traits as mania—but crucially, does so to a less severe and more functional degree. Historically, hypomanic temperament has received little attention compared to bipolar disorder, but the founders of modern psychiatry—Eugen Bleuler, Emil Kraepelin, Ernst Kretschmer—first described these personalities around a century ago. "Hypomanics," as I describe them in In Search of Bill Clinton: A Psychological Biography: 
 
 are whirlwinds of activity who are filled with energy and need little sleep, less than 6 hours. They are restless, impatient and easily bored, needing constant stimulation… and tend to dominate conversations. They are driven, ambitious and veritable forces of nature in pursuit of their goals. While these goals may appear grandiose to others, they are supremely confident of success—and no one can tell them otherwise…. They can be exuberant, charming, witty, gregarious but also arrogant…. They are impulsive in ways that show poor judgment, saying things off the top of their head, and acting on ideas and desires quickly, seemingly oblivious to potentially damaging consequences. They are risk takers who seem oblivious to how risky their behavior truly is. They have large libidos and often act out sexually. Indeed all of their appetites are heightened. 
 
 This description doesn't just match Clinton; it also sounds an awful lot like Trump. He reports, for example, “I usually sleep only four hours a night,” which by itself is usually a pretty reliable indicator of hypomania, and something he boasts about: “How can you compete against people like me if I sleep only four hours?” He claims to work seven days a week, and in a typical 18-hour day makes “over a hundred" phone calls and have “at least a dozen meetings.” “Without passion you don't have energy, without energy you have nothing!” Trump has tweeted. Hence his taunt of Jeb Bush as “a low energy person,” by contrast. Like most hypomanics, he is distractible. “Most successful people have very short attention spans. It has a lot to do with imagination,” he once wrote. He is correct. The same rapidity of thought that helps engender creativity makes it difficult to stay on one linear track of ideas without skipping to the next. Like most hypomanics, he follows his “vision, no matter how crazy or idiotic other people think it is.” Trump sees himself as a person of destiny and no one is going to talk him out of it. Trump's inflated self-esteem is illustrated by the fact that his net worth is reported by Forbes to be $4 billion, a fraction of the $10 billion he claims. It’s not just hyperbole: Hypomanics' wild optimism systematically distorts their perceptions. 
 
 Dripping with arrogance, Trump is an uber-aggressive alpha male who gleefully dominates, bullies, and colorfully disparages his competitors and critics. His hypomanic energy gives him that elusive charisma: Whether you love him or hate him (and charismatic figures produce such polarized responses) he makes himself the center of attention, the most exciting figure on the stage, who consumes all the oxygen in the room. But his impulsivity is manifested in his impolitic, unfiltered, outrageous statements, like his remark about Mexican immigrant "rapists." Many assume that one of these gaffes will ultimately bring him down, and they may be right. Leaders who live by their hypomania often die by it as well. ||||| CEASEFIRE OVER 
 
 The Donald renewed his verbal assault on Megyn Kelly last night, and the head of Fox News struck back for the first time in public, demanding an apology. 
 
 Donald Trump—self-avowed “ratings machine” though he might be—has finally gone too far for Fox News Chairman Roger Ailes. 
 
 The Republican presidential front-runner, who has spent the past day tweeting and re-tweeting nasty insults about Fox News star Megyn Kelly, owes her an apology, Ailes demanded in an extraordinary broadside against the reality-show billionaire, issued on Tuesday afternoon. 
 
 
 
 “Donald Trump’s surprise and unprovoked attack on Megyn Kelly during her show last night is as unacceptable as it is disturbing,” Ailes said about Trump, who has been a frequent interview guest on Fox & Friends, The O’Reilly Factor, Hannity, and other Fox News programs since the Republican presidential debate that Fox News broadcast on August 6 at which Kelly asked him a tough question about his history of calling women “fat pigs, dogs, slobs and disgusting animals.” 
 
 
 
 Trump immediately fired back in a statement. 
 
 “I totally disagree with the FOX statement. I do not think Megyn Kelly is a quality journalist. I think her questioning of me, despite all of the polls saying I won the debate, was very unfair. Hopefully in the future I will be proven wrong and she will be able to elevate her standards to a level of professionalism that a network such as FOX deserves.” 
 
 Ailes issued his statement a little more than 12 hours after Trump’s angry tweet storm. 
 
 “Megyn Kelly represents the very best of American journalism and all of us at FOX News Channel reject the crude and irresponsible attempts to suggest otherwise,” Ailes continued, referring to a raging series of Trump tweets in which the candidate claimed Kelly was “off her game” on her first show after a 10-day vacation, and retweeted a crass assertion that the former Washington litigator is a “bimbo.” 
 
 
 
 Ailes, who scheduled The Kelly File at the all-important 9 p.m. prime-time slot, went on: “I could not be more proud of Megyn for her professionalism and class in the face of all of Mr. Trump’s verbal assaults. Her questioning of Mr. Trump at the debate was tough but fair, and I fully support her as she continues to ask the probing and challenging questions that all presidential candidates may find difficult to answer. 
 
 
 
 “Donald Trump rarely apologizes, although in this case, he should. We have never been deterred by politicians or anyone else attacking us for doing our job, much less allowed ourselves to be bullied by anyone and we’re certainly not going to start now. All of our journalists will continue to report in the fair and balanced way that has made FOX News Channel the number one news network in the industry.” 
 
 
 
 Ailes's verbal howitzer against the front-running Republican—a highly unusual deployment for any news organization, let alone one that has been the GOP establishment and home of conservative viewers—comes after what seemed a coordinated defense of Kelly by at least 10 other Fox News personalities today on Twitter and on air. 
 
 According to CNN’s Brian Stelter, the pro-Kelly comments included Fox & Friends co-host Brian Kilmeade opining on Tuesday’s show that Trump is “totally out of control”; The Five co-host Dana Perino tweeting, “The intelligence, class & grace of Megyn Kelly shined last night after her week's vacation with her family"; anchor Bret Baier, Kelly’s co-moderator at the debate, tweeting that Trump "has made his feelings clear. But THIS needs to stop;" and Sean Hannity tweeting to Trump, "Leave @Megynkelly Alone."
– OK, now Donald Trump has gone too far: Though the Republican presidential candidate managed to remain on decent terms with Fox News after he first slammed Megyn Kelly, his latest remarks on the Fox host have apparently, finally, crossed the line as far as the network is concerned. Roger Ailes released a statement today, and he does not sound pleased. An excerpt, per USA Today: "Donald Trump’s surprise and unprovoked attack on Megyn Kelly during her show last night is as unacceptable as it is disturbing. Megyn Kelly represents the very best of American journalism and all of us at FOX News Channel reject the crude and irresponsible attempts to suggest otherwise. ... Donald Trump rarely apologizes, although in this case, he should." And Trump's quick response, per the Daily Beast: "I totally disagree with the FOX statement. I do not think Megyn Kelly is a quality journalist. I think her questioning of me, despite all of the polls saying I won the debate, was very unfair. Hopefully in the future I will be proven wrong and she will be able to elevate her standards to a level of professionalism that a network such as FOX deserves."
