"Trump privately rages."

Okay, to learn of this private rage I diligently read the story. I was thinking there would be some revelation coming from Trump's inner political circle or close friends. There's nothing. The author's make a unsubstantiated claim, offering not an iota of evidence. 

No one in Trump's camp is going to be happy about the email news. But to claim that he's "raging" about it paints a biased picture. It suggests he's emotionally unstable, and that there's substance to the innuendo flying around about his son's meeting with a Russian lawyer. After all, why would he get so worked up over nothing?

This story's closest relative is tabloid journalism. In the absence of any real news about a person of importance, the reporter makes something up about their personal feelings. The target can't refute the claim, because no one can prove that they never felt the way they were described. And if they challenge the claim, they just draw more attention to it.
