What Dirt does Donald Trump Have on Roger Ailes?

What dirt does Trump have on Roger Ailes?

That's the question that CNN's Brian Stelter is asking after reading another story by Fox nemesis Gabriel Sherman. 

In his self serving newsletter, Stelter about the Sherman article in which Sherman claims that Trump "ran the negotiations" between the Fox News founder and his ex-PR boss Brian Lewis.

Lewis was one of Ailes' MVPs -- until Ailes fired him in 2013. "During Lewis's severance negotiations, Lewis hired Judd Burstein, a powerhouse litigator, and claimed he had 'bombs' that would destroy Ailes and Fox News. That's when Trump got involved," Sherman writes.

Crucially, this info is not anonymously sourced: Trump is on the record saying Ailes "called me" to mediate. Trump brags: "Roger had lawyers, very expensive lawyers, and they couldn't do anything. I solved the problem."

Sherman writes that "Fox paid Lewis millions to go away quietly, and Trump, I'm told, learned everything Lewis had planned to leak."

OK, this might explain why Fox News talent such as Bill O'Reilly, Sean Hannity, Greta Van Susteren  and all of Fox and Friends appear to big Trump supporters. But, Fox News is one of the few networks to call Trump out. The network did release a public statement against Trump and his attacks on Megyn Kelly. 

So, the bigger question......
