New York Times reporter Sydney Ember has a problem with Bernie Sanders — which may be why the paper has her cover him.

Ember is supposed to write reported articles, not op-eds, but she consistently paints a negative picture of Sanders’s temperament, history, policies, and political prospects in the over two dozen pieces she’s done on him. This makes sense, given the New York Times’s documented anti-Sanders bias, which can be found among both editors and reporters alike.

The paper was caught making significant changes, without acknowledging them, to a 2016 article on Sanders hours after it went up: it changed the headline (from “Bernie Sanders Scored Victories for Years via Legislative Side Doors,” to “Via Legislative Side Doors, Bernie Sanders Won Modest Victories”); deleted a positive quote from a campaign adviser; and added two negative paragraphs.
