Fox, however, may have given Trump a little help. A pair of Fox insiders and a source close to Trump believe that Ailes informed the Trump campaign about Kelly’s question. Two of those sources say that they know of the tipoff from a purported eyewitness. In addition, a former Trump campaign aide says that a Fox contact gave him advance notice of a different debate question, which asked the candidates whether they would support the Republican nominee, regardless of who won. The former aide says that the heads-up was passed on to Trump, who was the only candidate who said that he wouldn’t automatically support the Party’s nominee—a position that burnished his image as an outsider.

These claims are hard to evaluate: [Roger] Ailes is dead, and they conflict with substantial reporting suggesting that the rift between Trump and Fox was bitter. A former campaign aide is adamant that Trump was genuinely surprised and infuriated by Kelly’s question. A Fox spokesperson strongly denied the allegations, and declined requests for interviews with employees involved in the debate.
