According to Barkan, the NYO’s endorsement of Trump, which was published without his knowledge or contribution, is just the latest in a series of questionable moves from the newspaper, which is owned by Trump’s son-in-law Jared Kushner.

Without giving specific examples, Barkan said he wasn’t allowed to give full coverage to certain aspects of the Trump campaign. Barkan also revealed that NYO editor-in-chief Ken Kurson  helped Trump prepare the speech he delivered to the American Israel Public Affairs Committee, an important lobbying group, in March.

Barkan told Politico: “The AIPAC situation was very troubling. Anyone knows that an editor in chief should not be reviewing the speech of a presidential candidate. I don’t care if it’s Trump or Bernie Sanders.”

The NYO editorial endorsing Trump was transparent about the newspaper’s relationship to the candidate, but also said this was not the reason for the endorsement. The op-ed began: “Donald Trump is the father-in-law of the Observer’s publisher. That is not a reason to endorse him. Giving millions of disillusioned Americans a renewed sense of purpose and opportunity is.”

The endorsement continued by arguing that Trump is “tapping into the pent-up desire of millions of voters to make America great again. It is not merely a political slogan; it is a vision and an attitude. It depends not on 14-point proposals or an SAT-like cramming of policy details. It depends on faith and leadership. Faith that Americans have the will to craft a brighter future, and the leadership to make it happen.”

Previously, conservative news outlet Breitbart News saw half a dozen staffers quit over its unofficial support for Trump, an internal disagreement that came to a head when one reporter, Michelle Fields, claimed that Trump campaign manager Corey Lewandowski  assaulted her at a campaign event.

Fields later tried to bring charges against Lewandowski, which were dismissed this week.
