The report severely challenges conventional wisdom that reporters and editors are referees on political playing field and bastions of neutrality who should not root for Team Red or Team Blue, either in word or deed.
As examples, the report cites New Yorker television critic Emily Nussbaum, a Pulitzer Prize winner, who has criticized Trump for running an "ugly and xenophobic campaign," without informing readers that she contributed $250 to Clinton in April.
The report also cites Carole Simpson, a former ABC "World News Tonight" anchor who now appears regularly on television representing Emerson College, where she works as distinguished journalist-in-residence, for giving Clinton $2,800.
On the Trump side, the report mentions Les Waldron, an Emmy Award-winning assignment editor at television station KFMB, the CBS affiliate in the US city of San Diego, for a $28 donation to the Republican candidate.
The report tally excluded donations from radio ideologues and paid TV pundits, who make no pretense of neutrality, focusing instead on reporters and editors at mainstream news outlets that often claim to embrace fair-minded and neutral reporting on political campaigns.
The results of research by the American Press Institute released in April revealed that only 6 percent of Americans trust the corporate media.
