Vivian Schiller, the embattled president and CEO of NPR, has resigned from the radio network. NPR posted a statement from Dave Edwards, Chairman of the Board of Directors, announcing Schiller’s departure: “The Board accepted her resignation with understanding, genuine regret, and great respect for her leadership of NPR these past two years.” The statement also notes that her resignation arrives after “a traumatic period for NPR.” Schiller had been at the center of the controversial firing in October of NPR analyst Juan Williams, who was dismissed after making statements about Muslims on The O’Reilly Factor. (Schiller later apologized for the handling of Williams’ firing.) Yesterday brought more embarrassment: according to the Washington Post, an undercover video filmed by conservative activist James O’Keefe features NPR executive Ron Schiller (no relation to the exiting CEO) saying that Tea Party followers aren’t “just Islamophobic, but really xenophobic… They believe in sort of white, middle-America gun-toting. I mean, it’s scary. They’re seriously racist, racist people.”
