According to people close to both sides, Trump has told White House staffers that he feels personally betrayed by CNN chief Jeff Zucker.

Trump complains that Zucker should be programming CNN more favorably toward him because of their long relationship, which can be traced back to 2004 when Zucker put The Apprentice on NBC. Trump has also said to White House staffers that Zucker owes him because Trump helped get him the job at CNN.

According to CNN sources, Trump’s claim that he assisted Zucker in landing the top job at the network is false. Trump seems to have gotten the idea because he praised Zucker to Turner Broadcasting’s then-CEO Phil Kent at a charity dinner in the fall of 2012, a few months before CNN hired Zucker. But CNN sources say Turner had already decided to hire Zucker by that point. “This is entirely personal,” one CNN high-level source said. “Trump thinks just because he’s known Jeff that CNN should be covering him like Fox News does.”
