American Public Media’s president, Jon McTaggart, won re-election to the NPR Board this summer but won’t be taking the seat after all. McTaggart resigned from the board at NPR’s request after an outside legal analysis determined that his promotion to president of APM and Minnesota Public Radio presented a potential conflict of interest with his service on the NPR Board. Since his first election to the board three years ago, McTaggart had been promoted from chief operating officer to chief exec of American Public Media Group, the parent company of APM/MPR. That put him uniquely and simultaneously on the boards of the two largest producers and distributors of public radio programming. Marita Rivero, v.p. and g.m. of WGBH’s television and radio stations, will fill the NPR Board vacancy instead.
